EMBODIMENTS

The present invention is directed to conveying notifications via accessories that are not in use with the device determining an event that triggers the notifications. For example, a device may have previously been paired with an accessory capable of conveying a notification, but the accessory may, when the event occurs, be in use with a different, second, device. The devices may be correlated with each other via a storage entity, such as, for example, a cloud storage storing a subscription or account. The device determining the event may send a notification to the storage entity, which may be capable of notifying the second device. The second device may, in turn, notify the user via the accessory.

The inventor has realised that certain aspects of communication and operation may be improved upon. To this effect, the following describes several aspects and embodiments, which may be implemented in isolation or in combination with each other, for achieving the advantages described hereunder.

Accessories in general cover a wide range of devices designed for different purposes, for example, a detachable lens mechanism may enhance optical performance of a user camera, a virtual reality headset may enable virtual immersion of a surgeon into a blood vessel of a patient, based on image data obtained from a video sensor inserted in the blood vessel. To enable interoperation of generic accessories with devices produced by a diverse set of manufacturers, industry standards have been developed. Such standards may define physical and/or operational characteristics of accessories that are to be capable of interoperation in accordance with these standards. For example, a standard headphone connection may define a 3,5 millimetre physical connector, as well as electrical characteristics of an audio signal that is to be provided via the physical connector. Other type connectors exist too.

Certain accessories enable notification of a user concerning an event. For example, when a user listens to a radio broadcast with headphones, the headphones may relay information concerning an incoming telephone call, in case the software radio is comprised in a cellular telephone apparatus. The user may handle the incoming call, and then return to the software radio broadcast, without removing his headphones. Likewise a user driving a car may receive and even initiate telephone calls or social media updates using a hands-free accessory, which may be voice-directed, for example, without letting go of the steering wheel.

FIGURE 1 illustrates an example system in accordance with at least some embodiments. Device 110, which may comprise, for example, a user device, user equipment, mobile phone, smartphone, tablet device, laptop computer, desktop computer or another suitable device, may be in wireless communication with base station 120.

In some embodiments the user may have different devices registered as his own devices like one or more smart phones, laptops or tablets. The user may have a control or a limited control of some other smart phones, laptops or tablets or some other electronic devices which are registered in different accounts.

To achieve interoperability, mobile 1 10 and base station 120 may be configured to operate in accordance with a same communication technology, such as, for example, a cellular or non- cellular technology. Examples of cellular communication technologies include wideband code division multiple access, WCDMA, long term evolution, LTE, and fifth generation, 5G, also known as new radio, NR. Examples of non-cellular communication technologies include wireless local area network, WLAN, and worldwide interoperability for microwave access, WiMAX, technologies. However, in some embodiments, the base station may also operate under different radio access technologies, RATs, such as LTE and 5G. Radio link 112 connects device 110 with base station 120. Radio link 1 12 may be arranged in accordance with a same communication technology as device 110 and base station 120, to achieve interoperability. As said, base station 120, as well as device 110, may be capable of communicating also with other communication technologies. The expression "base station" is a terminological choice by which it is not intended to limit the present disclosure to any specific technology. Depending on a communication techno logy used, the expression "access point" may be used alternatively to "base station". The expression "access node" may comprise either a base station or an access point. Base station 120 may be a virtual base station, or function as a virtual base station.

Base station 120 is operably connected, via connection 124, with network node 141, which may comprise, for example, a mobility management entity, MME, switch or base station controller. Network node 141 may communicate with further networks via connection 147, an example of such a network being provided in the system of FIGURE 1 as network 170.

Although described herein in connection with FIGURE 1 as a wirelessly connected device, in general device 110 may comprise, for example, a desktop computer with a wire-line Ethernet connection to the Internet. Such a desktop computer may receive, for example, incoming internet protocol telephony calls as events.

Accessory 140 may be, in the system of FIGURE 1, in one of two positions, A or B. In position A, accessory 140 is in use with device 110 via connection 114, and in position B, it is in use with unit 150 via connection 154. Accessory 140 may comprise, for example, a headset, earplugs or a virtual reality headset. A headset, and likewise earplugs, is usable in emitting sound to the user's ear or ears, such that the user may listen to music, for example, without disturbing persons around him. A virtual reality headset enables at least partial immersion in a virtual landscape by providing a visual experience of being in the virtual landscape. A virtual reality headset may comprise an audio headset. A common factor in these three kinds of accessory is that they decrease the user's concentration in audio cues present in his surroundings. The virtual reality headset decreases the user's concentration also concerning visual cues, since the virtual landscape provided thereby obscures the real surroundings of the user. Connection 114 between accessory 140 and device 110 may comprise an electrically conductive wire or a low-power wireless connection, such as Bluetooth, BLE, or corresponding technologies, for example.

The system of FIGURE 1 further comprises a storage entity 160. Storage entity 160 may comprise, for example, a cloud storage or cloud server farm configured to store account or subscription information. For example, a service provider providing or coordinating a device ecosystem may gather information on devices in use by a specific user, to facilitate access to a cloud data storage directory from different devices of the user, for example. A subscription account may be physically at storage entity 160, for example. Transmitting information to storage entity 160 may thus comprise transmitting information for storage in the account of the user, the account comprising information of devices the user has in use. Storage entity 160 may communicate with device 110 via connection 167 and network 170, and storage entity 160 may communicate with unit 150 via connection 186, network 180 and connection 158. Networks 170 and 180 may be optional, they may be the same network and/or storage entity 160 may be disposed in at least one of these networks. When in use with device 110, accessory 140 may be used by device 110 to notify the user concerning an event of device 110, such as an incoming telephone call or social media update, for example. A further example of an event is a carbon monoxide alarm, in embodiments where device 110 is interfaced with an optional carbon monoxide sensor 111. In general, the event may be determined in device 110 independently of other network nodes, as in the case of carbon monoxide or carbon dioxide level alarm, or the event may be determined in device 110 responsive to a signal received in device 110 from another network node , for example network node 141, as in the case of an incoming call.

When in use with unit 150, accessory 140 may be used to provide sensory inputs relating to operating unit 150, which may comprise, for example, a gaming console or radio. Connection 154 between accessory 140 and unit 150 may comprise an electrically conductive wire or a wireless connection, such as Bluetooth, BLE, for example.

When initially paired with device 110, accessory 140 may participate, together with device 110, in generation of pairing information. Pairing information may comprise identifiers of paired devices and, optionally, encryption keys used, such that when the devices are subsequently used together, the initial pairing process need not be repeated, which facilitates using the accessory. Alternatively, device 110 may simply inform storage entity 160 that accessory 140 is paired or in use with device 110.

Device 110 may provide the pairing information to storage entity 160, which may store it in connection with an account of the user. When the user later uses accessory 140 with unit 150, the pairing information may be retrieved from storage entity 160, for example, to facilitate taking accessory 140 into use with unit 150. Unit 150 may inform storage entity 160 that accessory 140 is being used with unit 150, when accessory 140 is being used with unit 150.

As accessory 140 is used with unit 150, the user may have a reduced concentration to receiving notifications from device 110. For example, an audible alarm from device 110 may be difficult to hear over a sound level produced by earplugs used with unit 150. Thus the user may miss events that are notified by device 110.

Device 1 10 may be configured to notify storage entity 160 of an event in device 110. Storage entity 160 may, responsive to the notification from device 110, determine whether an accessory 140 is in use with another device than device 110, and responsive to a determination in storage entity 160 that accessory 140 is in use with unit 150, storage entity 160 may notify unit 150 concerning the event in device 110.

The notifications from device 110 and from storage entity 160 may comprise information concerning the event, for example, at least one characteristic of the event. Such a characteristic may comprise an event type and/or data concerning the event. For example, the characteristics may comprise an event type "Alarm" and associated data "carbon monoxide". Another example is an event type "Incoming call", which may be accompanied by a caller-ID of the calling party, and/or a picture of the face of the caller.

Unit 150 may be configured to notify the user, via accessory 140, responsive to the notification from storage entity 160. For example, in case of carbon monoxide alarm, an alarm sound may be played, accompanied by a spoken notification "Carbon monoxide danger". As another example, a spoken notification "Your phone is ringing, Joe is calling" may be provided. As a yet further example, an e-mail message incoming in an email account associated with device 110 may be notified using a same audio signal as device 110 uses to notify an incoming e-mail.

In some embodiments, device 110 is configured to query, for example responsive to determining the event, from storage entity 160, whether accessory 140, or more generally any accessory, is in use. Device 110 may then be configured to notify storage entity 160 responsive to an indication from storage entity 160 that an accessory is indeed in use.

In some embodiments storage entity 160 may have a status information of the accessory 140, for example in the form "in use" or "free". In other embodiments storage entity 160 may have also information that accessory 140 is in use with unit 150. In yet further embodiments the storage entity 160 can have information about the time stamp of last used of accessory 140 and by which device, such as, for example, unit 150, used at that time. That might help user to find accessory faster. That information can be shown in connection with a call to or from device 140 or by a request of the device 140 as a way of notification, icon or so.

In some, embodiments, device 110 will refrain from notifying storage entity 160 of the event in case device 110 has not been paired with an accessory of a first type in the past. In other embodiments, device 110 is configured to attempt to find out, if an accessory of the first type is in use with another device of the user regardless of whether one has been in use with device 110 before.

The first type may comprise a type which decreases a user's concentration in audio and/or video cues present in his surroundings, for example. Accessories may comprise, in an identifying data field, an indication as to whether they are accessories of the first type. This indication may be provided to device 110 and/or unit 150 when the accessory is taken into use with them. The indication may be provided onward to storage entity 160 in connection with informing the storage entity the accessory is in use, to enable the storage entity to advise other devices that an accessory of the first type is in use, and/or in deciding whether to provide a notification to a specific device. In detail, the storage entity may be configured to decide to notify a device that is using an accessory of the first type.

In some of these embodiments, device 110 will refrain from notifying storage entity 160 of the event in case device 110 is currently using the accessory of the first type with which it has been paired.

In some embodiments, device 110 is configured to query, for example responsive to determining the event, from storage entity 160, whether an accessory of the first type is in use by the user, and to notify storage entity 160 of the event responsive to being informed that an accessory of the first type is in use by the user. Thus the accessory that is in use need not necessarily be one that has been paired with device 110 in the past.

In some embodiments, device 110 is configured to notify storage entity 160 without querying from storage entity 160 responsive to the event. For example, device 110 may notify storage entity 160 simply responsive to the event occurring at a time when the user is not using an accessory of the first type with device 110 itself.

Once storage entity 160 has been notified by device 110, it may decide on a further apparatus, such as unit 150, to notify. In detail, storage entity 160 may decide to notify a further apparatus that is using an accessory, for example an accessory of the first type. In case storage entity 160 cannot determine any suitable apparatus to notify, it may discard the notification it has received from device 110. Device 110 may be configured to provide contents of the event to unit 150, via storage entity 160 or by otherwise routing it. For example, storage entity 160 may, in addition to notifying unit 150 of the event, advise device 110 concerning an internet protocol address of unit 150 to enable device 110 to forward contents of the event to unit 150. The internet protocol address may comprise an IPv4 or IPv6 address, for example. In detail, where the event is an incoming call, device 110 and unit 150 may be configured to route the call to unit 150, such that accessory 140 is used with unit 150 to convey the call.

FIGURE 2 illustrates example notifications. The notifications may be transmitted from device 110 of FIGURE 1, for example. In some embodiments, storage entity 160 forwards the notifications it receives from device 110 to unit 150, or in general to an apparatus that is using an accessory, such as, for example, an accessory of the first type. Notification 201 comprises two characteristics, event type 210 and event information 220. As described above, the event type may comprise an incoming call and event information may comprise a caller identity.

Notification 202 comprises three characteristics, event type 230, event information 240 and a media part 250. Event type 230 may be similar to event type 210 and event information 240 may be similar to event information 220. Media part 250 may comprise, for example, a media file, such as audio clip, the user of device 110 has selected for notifying an event of event type 230. This enables the user to be notified of an incoming e-mail, for example, with the same chime as usually, from device 110. Alternatively, in case the user is of impaired hearing and has configured device 110 to notify himself with a visual flash, unit 150 may provide the same visual flash, enabling successful notification. Media part 250 may comprise information describing the visual flash. Media part 250 may comprise an image of the face of the caller associated with a caller ID. In one embodiment, media part 250 may comprise an Internet address. In some embodiments media part 250 may comprise a request to open a chat or messaging window. Storage entity 160 may comprise plural accounts of users. The users may be linked to send messages or video calls through one or more applications in devices 110, or units 150, when connected to a suitable communication network. Thus, for example, in case of incoming call which is notified by storage entity 160, the storage entity may start an application for communication between users, that is, between a caller and a called person.

In some embodiments storage entity 160 may work together with other entities which are administrated by other entity owners. In one embodiment the interface between different storage entities may be interoperable to facilitate communication, forexample, to exchange relevant user information.

The event may comprise a communication event, such as, for example, an incoming call. Alternatively, the event may comprise an alarm. An alarm may relate to, for example, carbon monoxide or smoke. The storage entity may comprise a cloud computing entity, for example. Notifying may comprise transmitting a notification which comprises at least one characteristic of the event.

FIGURE 6 is a flow graph of a method in accordance with at least some embodiments. The phases of the illustrated method may be performed in unit 150, for example, or in a control device configured to control the functioning thereof, when installed therein.

Phase 610 comprises notifying a storage entity that an apparatus performing the method is using an accessory. Phase 620 comprises receiving from the storage entity an indication of an event relating to a second apparatus. Finally, phase 630 comprises providing a sensory indication of the event via the apparatus, the accessory, or a combination thereof.

In some embodiments, after the event notification has reached a current device using the accessory apparatus, a connection between the current device using the accessory apparatus is stopped and/or the presentation of a current presentation is stopped. A connection between the accessory and the second apparatus may be established. This might facilitate avoiding a missed call. After the call has been finished, the operation with the apparatus may continue as it was before the event.

FIGURE 7 is a flow graph of a method in accordance with at least some embodiments. The phases of the illustrated method may be performed in storage entity, for example, or in a control device configured to control the functioning thereof, when installed therein.

Phase 710 comprises receiving, from a first apparatus, information relating to pairing an accessory with the first apparatus and receiving, from a second apparatus, an indication the second apparatus is using the accessory. Phase 720 receiving from the first apparatus a notification of an event relating to the first apparatus. Finally, phase 730 comprises notifying the second apparatus, the accessory, or a combination thereof of the event.

FIGURE 8 illustrates signalling in accordance with at least some embodiments. On the vertical axes are disposed on the left, device 110, in the centre, storage entity 160 and unit 150, and on the right, accessory 140, each of FIGURE 1. Time advances from the top toward the bottom. Phase 810 illustrates an ongoing media stream, for example a music stream, from unit to accessory 140. Phase 820 is a notification from device 110 concerning an incoming call as described herein above. Storage entity 160 notifies unit 150 concerning the call in phase 830, responsive to which unit 150 queries from the user 840, whether he will accept or reject the call. In the illustrated example the user accepts the call, responsive to which the music may be paused, for example, and a redirection process 850 may be performed. The user may participate in the call via accessory 140 in phase 850. The redirection process may comprise conveying content of the call via a packet-based connection between device 110 and accessory 140, for example. Thus unit 150 provides contents of the incoming call to the user via accessory 140, the contents being routed to the apparatus from device 110.

Once the call ends, the redirected connection of phase 850 may be disconnected, after which a connection 860, similar to connection 810, is built, or resumed, between unit 150 and accessory 140. The media session of phase 810 is continued in phase 870.

While an incoming call is used as an example of an event in connection with FIGURE 8, other kinds of events are also applicable.

FIGURE 9 illustrates signalling in accordance with at least some embodiments. On the vertical axes are disposed on the left, device 110, in the centre, storage entity 160 and unit 150, and on the right, accessory 140, each of FIGURE 1. Time advances from the top toward the bottom. The signalling of FIGURE 8 relates to connection redirection, as was used in the process of FIGURE 8, for example. Phase 910 comprises a disconnect, for example relating to the media session of phase 810 of FIGURE 8. Phases 920 and 930 may comprise a notification of the disconnection being relayed to storage entity 160 and device 110, respectively.

Phase 940 may comprise a request to create a connection for the redirection, for example a packet-based connection, such as real-time transport protocol, RTP, or transmission control protocol, TCP, connection, for example. The connection is established in phase 950. Establishing the connection may comprise an end-to-end handshake and/or ciphering negotiation, for example.

Phase 960 comprises a notification of disconnection of the call, which may be conveyed over the connection of phase 950, for example. Storage entity 160 is notified of the disconnection on phase 970, and storage entity 160 may notify unit 150 of the disconnection in phase 980. Phase 980 may comprise a "140 disconnected" message, for example. The message of phase 990 may trigger re-establishment of a media session between unit 150 and accessory 140, for example. It is to be understood that the embodiments of the invention disclosed are not limited to the particular structures, process steps, or materials disclosed herein, but are extended to equivalents thereof as would be recognized by those ordinarily skilled in the relevant arts. It should also be understood that terminology employed herein is used for the purpose of describing particular embodiments only and is not intended to be limiting.

Reference throughout this specification to one embodiment or an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment.
