A communication system known as evolved UTRAN (E-UTRAN, also referred to as UTRAN-LTE or as E-UTRA) has been specified within 3 GPP. The DL access technique is OFDMA, and the UL access technique is SC-FDMA.

One specification of interest is 3 GPP TS 36.300, V10.4.0 (2011-06), "3rd Generation Partnership Project; Technical Specification Group Radio Access Network; Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Access Network (E-UTRAN); Overall description; Stage 2 (Release 10)".

Figure 1 reproduces Figure 4-1 of 3GPP TS 36.300, and shows the overall architecture of the E-UT AN system. The E-UTRAN system includes eNBs, providing the E-UTRA user plane (PDCP/RLC MAC/PHY) and control plane (RRC) protocol terminations towards the UE. The eNBs are interconnected with each other by means of an X2 interface. The eNBs are also connected by means of an SI interface to an EPC, more specifically to a MME (Mobility Management Entity) by means of a SI MME interface and to a Serving Gateway (SGW) by means of a SI interface. The SI interface supports a many-to-many relationship between MMEs/S-GW and eNBs.

Reference can also be made to 3 GPP TS 31.102 V10.2.0 (2011-06) Technical Specification 3rd Generation Partnership Project; Technical Specification Group Core Network and Terminals; Characteristics of the Universal Subscriber Identity Module (USIM) application (Release 10).

3G cards are UICCs and store a SIM/USIM application. Previous 2G cards are referred to simply as SIM cards. A conventional UICC card or SIM card is issued by an operator and is used with one radio instance. As such, no problem is presented for the operator or some requestor to locate a needed application on the card.

Various devices may allow a user to access multiple subscriptions from the same device via a smart card platform (SCP). This smart card platform may be hosted by a removable module like today or be embedded. Another example is a new phone that may include additional card slots which enable the additional subscriptions. Some UICC (e.g., eUICC, a universal integrated circuit card, etc.) even allow several applications on the same card (e.g. USIM and ISIM or multiple USIMs/ISIMs). In other devices, a subscription may be downloaded to the device over the air or over other bearers like WLAN. An eUICC present in the terminal may store applications from multiple operators and/or different security modules in the same terminal that hold the same application. See further: 3 GPP TR 33.812 V9.2.0 (2010-06), "3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Feasibility study on the security aspects of remote provisioning and change of subscription for Machine to Machine (M2M) equipment (Release 9)". Such a download mechanism would enable users to choose the best operator, e.g., depending on their location or service need.

What is needed is a means for older, legacy systems, which may not be fully compatible with an eUICC and/or has a limited number of card slots, to be able to access functionality available in newer phones.

DETAILED DESCRIPTION

Exemplary embodiments in accordance with this invention enable an existing phone (e.g., a legacy phone) to be "enhanced" in order to support multi-SIM, for example, by a downloaded subscription. This enhancement can take place at a physical shop, or could be an application downloaded or pushed to the device. Exemplary embodiments in accordance with this invention also allow a legacy phone to use an eUICC. The phone may be equipped with an additional card (e.g., a memory card) or an UICC card which supports downloading of subscriptions. Exemplary embodiments in accordance with this invention also provide a downloadable application which can upgrade a legacy device so that an eUICC can be inserted in a legacy phone and operate as a legacy UICC.

An eUICC may refer to additional functionality available on a (reasonable) secure element. The element can be a UICC card or a secure memory card. Alternatively, an eUICC may refer to the element which provides eUICC functionality. Thus, a single subscriber identity module may appear to a terminal like multiple identity modules, e.g., by means of virtual modules. The terminal may have one physical reader.

Before describing in further detail various exemplary embodiments of this invention, reference is made to Figure 2 for illustrating a simplified block diagram of various electronic devices and apparatus that are suitable for use in practicing exemplary embodiments of this invention.

In the wireless system 230 of Figure 2, a wireless network 235 is adapted for communication over a wireless link 232 with an apparatus, such as a mobile communication device which may be referred to as a UE 210, via a network access node, such as a Node B (base station), and more specifically an eNB 220. The network 235 may include a network control element ( CE) 240 that may include the MME/SGW functionality shown in Figure 1 , and which provides connectivity with a network, such as a telephone network and/or a data communications network (e.g., the internet 238).

The UE 210 includes a controller, such as a computer or a data processor (DP) 214, a computer-readable memory medium embodied as a memory (MEM) 216 that stores a program of computer instructions (PROG) 218, and a suitable wireless interface, such as radio frequency (RF) transceiver 212, for bidirectional wireless communications with the eNB 220 via one or more antennas.

The eNB 220 also includes a controller, such as a computer or a data processor (DP) 224, a computer-readable memory medium embodied as a memory (MEM) 226 that stores a program of computer instructions (PROG) 228, and a suitable wireless interface, such as RF transceiver 222, for communication with the UE 210 via one or more antennas. The eNB 220 is coupled via a data/control path 234 to the NCE 240. The path 234 may be implemented as the SI interface shown in Figure 1. The eNB 220 may also be coupled to another eNB via data/control path 236, which may be implemented as the X2 interface shown in Figure 1.

The NCE 240 includes a controller, such as a computer or a data processor (DP) 244, a computer-readable memory medium embodied as a memory (MEM) 246 that stores a program of computer instructions (PROG) 248.

At least one of the PROGs 218, 228 and 248 is assumed to include program instructions that, when executed by the associated DP, enable the device to operate in accordance with exemplary embodiments of this invention, as will be discussed below in greater detail.

That is, various exemplary embodiments of this invention may be implemented at least in part by computer software executable by the DP 214 of the UE 210; by the DP 224 of the eNB 220; and/or by the DP 244 of the NCE 240, or by hardware, or by a combination of software and hardware (and firmware).

The UE 210 and the eNB 220 may also include dedicated processors, for example memory controller 215. In general, the various embodiments of the UE 210 can include, but are not limited to, cellular telephones, tablets, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wireless communication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback appliances having wireless communication capabilities, Internet appliances permitting wireless Internet access and browsing, as well as portable units or terminals that incorporate combinations of such functions.

The computer readable MEMs 216, 226 and 246 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory. The DPs 214, 224 and 244 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on a multicore processor architecture, as non-limiting examples. The wireless interfaces (e.g., RF transceivers 212 and 222) may be of any type suitable to the local technical environment and may be implemented using any suitable communication technology such as individual transmitters, receivers, transceivers or a combination of such components.

Figure 3 illustrates further detail of an exemplary UE in both plan view (left) and sectional view (right), and the invention may be embodied in one or some combination of those more function-specific components. At Figure 3 the UE 210 has a graphical display interface 320 and a user interface 322 illustrated as a keypad but understood as also encompassing touch-screen technology at the graphical display interface 320 and voice-recognition technology received at the microphone 324. A power actuator 326 controls the device being turned on and off by the user. The exemplary UE 210 may have a camera 328 which is shown as being forward facing (e.g., for video calls) but may alternatively or additionally be rearward facing (e.g., for capturing images and video for local storage). The camera 328 is controlled by a shutter actuator 330 and optionally by a zoom actuator 332 which may alternatively function as a volume adjustment for the speaker(s) 334 when the camera 328 is not in an active mode.

Within the sectional view of Fig. 3 are seen multiple transmit/receive antennas 336 that are typically used for cellular communication. The antennas 336 may be multi- band for use with other radios in the UE. The operable ground plane for the antennas 336 is shown by shading as spanning the entire space enclosed by the UE housing though in some embodiments the ground plane may be limited to a smaller area, such as disposed on a printed wiring board on which the power chip 338 is formed. The power chip 338 controls power amplification on the channels being transmitted and/or across the antennas that transmit simultaneously where spatial diversity is used, and amplifies the received signals. The power chip 338 outputs the amplified received signal to the radio-frequency (RF) chip 340 which demodulates and downconverts the signal for baseband processing. The baseband (BB) chip 342 detects the signal which is then converted to a bit-stream and finally decoded. Similar processing occurs in reverse for signals generated in the apparatus 210 and transmitted from it.

Signals to and from the camera 328 pass through an image/video processor 344 which encodes and decodes the various image frames. A separate audio processor 346 may also be present controlling signals to and from the speakers 334 and the microphone 324. The graphical display interface 320 is refreshed from a frame memory 348 as controlled by a user interface chip 350 which may process signals to and from the display interface 320 and/or additionally process user inputs from the keypad 322 and elsewhere.

Certain embodiments of the UE 210 may also include one or more secondary radios such as a secondary cellular radio chip, a wireless local area network radio WLAN 337 and a Bluetooth® radio 339, which may incorporate an antenna on-chip or be coupled to an off-chip antenna. Throughout the apparatus are various memories such as random access memory RAM 343, read only memory ROM 345, and in some embodiments removable memory such as the illustrated memory card 347. The various programs 218 are stored in one or more of these memories. All of these components within the UE 210 are normally powered by a portable power supply such as a battery 349.

Embodiments of this invention are most relevant to the UE 210, DP 214, MEM 216 and memory controller 215, though it is noted that other embodiments need not be disposed there but may be disposed across various chips and memories as shown or disposed within another processor that combines some of the functions described above for Figure 3.

Processors 338, 340, 342, 344, 346, 350, if embodied as separate entities in a UE 210 or eNB 220, may operate in a slave relationship to the main processor 214, 224, which may then be in a master relationship to them. Any or all of these various processors of Fig. 3 access one or more of the various memories, which may be on-chip with the processor or separate therefrom. Similar function-specific components that are directed toward communications over a network broader than a piconet (e.g., components 336, 338, 340, 342-345 and 347) may also be disposed in exemplary embodiments of the access node 220, which may have an array of tower-mounted antennas rather than the two shown at Fig. 3.

Note that the various chips (e.g., 338, 340, 342, etc.) that were described above may be combined into a fewer number than described and, in a most compact case, may all be embodied physically within a single chip.

Figure 4 shows another simplified block diagram of an exemplary electronic device that is suitable for use in practicing various exemplary embodiments of this invention. UE 210 may include one or more card 252. A card 252 may be an UICC or a SIM. A card 252 and/or MEM 216 may be removable. A subscription may be active on a card 252 or the subscription may reside on the UE 210 and be bound to the presence of the card 252.

Two cards 252 are shown, however, there may be more or less depending on the number of slots available. A first card 252 (e.g., UICC 1) may be designated as a primary subscription and a second card 252 (e.g., UICC 2) may be designated as secondary. These roles may be assigned by which slot is used for the card 252 and/or by system/user settings. Depending on the system configuration both the primary subscription and the secondary subscription may be able to receive calls and/or incoming data. Likewise, the primary subscription and the secondary subscription can individually make calls and/or establish data connections.

Various exemplary embodiments in accordance with this invention outline methods to "upgrade" an existing device (e.g., a legacy device) to enable multi-SIM use. In a first non-limiting exemplary embodiment, the user may receive a card (e.g., an UICC card or a memory card) that supports downloading of subscriptions. The upgrade may be done via an application. In a second non-limiting exemplary embodiment, a method provides for an eUICC to be used in a legacy phone by implementing the eUICC using one of the standardized "SIM" card form factors.

An application as used in the first exemplary embodiment can detect whether a physical component (e.g., a card) supports downloading of subscriptions (e.g., an eUICC) or a legacy UICC which does not support downloading. When detecting that the component is an eUICC, the terminal informs the eUICC that it is capable of handling the eUICC, with a virtual UICCs (e.g., each operator would have his own virtual UICC on the eUICC).

The terminal can detect whether or not the physical component supports downloading of subscriptions based on an AT or by issuing a command sequence (e.g. PPS). The ATR is a set of bytes that are delivered to the terminal when the component is powered up and exit reset. The eUICC indicates in the ATR, e.g., at power up, that it is an eUICC and supports subscription download functionality. The ATR can be presented directly to an interface. It can additionally be represented in a file. Alternatively, the terminal could use a command sequence, e.g., a PPS procedure, to see if the card accepts the download of subscriptions. If the UICC doesn't accept the PPS procedure the terminal knows that the card does not accept downloading of subscriptions. If the terminal is able to support multi-SIM use (e.g., from the radio side), then the terminal may use a PPS procedure to indicate to the eUICC that the terminal is an eUICC capable terminal. The PPS allows the terminal to tell a component (e.g., an eUICC/UICC) how to behave. The terminal can select if the component behaves like an eUICC or an UICC. A default for the physical component may be to behave as an UICC until instructed differently.

When operating as an UICC, there may not be any provisioning network access application (NAA) available or if the provisioning NAA is available it may have a separate application identity (AID) different from the operational NAAs so that it doesn't get used (e.g., in a legacy terminal). Which applications are shown to the terminal when operating as an UICC may also depends on a configuration used in a previous session. Alternatively, there may be an NAA application on an eUICC but this NAA may not be visible to the terminal when operated in the UICC mode. Thus, the NAA of the eUICC may be considered as not available.

When the eUICC detects that the terminal is eUICC enabled (e.g., in a protocol and parameter selection (PPS) procedure), the eUICC may indicate that the eUICC has a provisioning capability (e.g., by changing the content of EFQ _IR SO that the provisioning NAA AID is now part of the EF _D1 R content and is thereby shown to the terminal). The content of the EFQ _IR are changed so that "new" or more applications are visible to the eUICC enabled terminal. Thus, the terminal and the eUICC are aware of each other's capabilities. The eUICC may reside on an UICC card or in a second element in the terminal (e.g., a memory card).

Section 13 of 3 GPP TS 31.101 VIO.0.1 (2011-06) Technical Specification 3rd Generation Partnership Project; Technical Specification Group Core Network and Terminals; UlCC-terminal interface; Physical and logical characteristics (Release 10), "Application independent files", states that there are four EFs at the Master File (MF) level specified in ETSI TS 102 221 clause 13 (EF _ICCI D; EF _DIR , EF _pl and EF _ARR ), for 3 GPP. The EF _DIR file contains the application identifiers (AIDs) and the application labels of the 3GPP applications present on the card. The AIDs of 3GPP applications are defined in ETSI TS 101 220. The 3GPP applications can be selected by means of the AID selection, as specified in TS 31.101. The EFDIR entry is specified as not containing a path object for application selection, and it is recommended that the application label does not contain more than 32 bytes. See further ETSI TS 102 221 V8.2.0 (2009-06) Technical Specification; Smart Cards; UICC-Terminal interface; Physical and logical characteristics (Release 8).

Once an eUICC is detected and the terminal has set the eUICC into "eUICC mode", the terminal may use the new or enhanced commands (e.g., usage of multiple application numbers, multiple radio instance iteration, enhanced user interface, etc.).

Thus, a legacy terminal running such an application and with the eUICC inserted becomes a multi-SIM terminal (e.g., by using virtual UICCs (vUICC) rather than multiple applications, e.g., SIMs, USIMs, or a combination of SIMs and USIMs). This allows UICC management mechanisms to be used by network operators which rely on multiple UICC.

Figure 5 depicts a block diagram of various profiles usable by an exemplary electronic device that is suitable for use in practicing various exemplary embodiments of this invention. The service control point is divided in several vUICC, each subscription manager manages one or more vUICC. The subscription manager can access the vUICCs to which the subscription manager is in possession of the relevant vUICC specific credentials. The subscription manager assists in downloading the subscriptions to the vUICC.

As shown, a first mobile network operator (MNOl) provides a first profile, MNO 1 profile. This profile is usable under a first subscription manager (SMI). This profile will allow downloading of further network access credentials. The SMI provides eUICC access credentials and SMI specific data. A profile includes credentials for the MNO and enable network access by containing a NAA. In addition the profile may contain credentials for the donating (MNO). NAA with network access credentials are also included in the profile. Control mechanisms (e.g., for deletion, updating, etc.) may be part of a profile's control policies and also stored in the profile.

A second mobile network operator (MN02) provides two profiles, MNO 2 profile. These profiles are usable under a second subscription manager (SM2). The SM2 provides eUICC access credentials and SMI specific data. One or both of these profiles may be active (e.g., if allowed and possible) while the other is inactive. Two or more profiles from different MNOs may be active at the same time to simulate a "dual or multiple SIM" terminal.

As shown, a third mobile network operator (MN03) provides a third profile, profile 3, and a fourth profile, profile 4. These profiles are also usable under SMI . Both may be active.

Based on the foregoing it should be apparent that the exemplary embodiments of this invention provide a method, apparatus and computer program(s) to enable use of multiple subscriber identity module applications in UICCs. It should be noted, that the embodiments contains several vUICC which are bound to specific SMs. The role of the SM can also be taken by an operator. The device may then contain one or more active subscriptions that do not interfere with each other, e.g., MN02 has no management possibility over the MN03 profile and vice-versa.
