Title

Optimizations for cloud storage related data flow

Field

The present invention relates to optimizations for cloud storage related data flow. More specifically, the present invention exemplarily relates to measures (including methods, apparatuses and computer program products) for realizing optimizations for cloud storage related data flow.

Background

The present specification generally relates to optimization and synchronization of data traffic to a backend cloud storage like shared data layer (SDL) for example in the Internet- of-Things (loT) and 3rd Generation Partnership Project (3GPP) 5th Generation (5G) networks to cater to explosive data traffic growth and reduce latency to virtual zero.

Currently, data generated by loT devices (machine type communication (MTC) and device-to-device (D2D)) in 4th Generation (4G) and 5G networks take data flow paths which terminate at the loT application server/Proximity Services (ProSe) application server, which resides behind the application enablement platform AEP. The applications (at the respective application server) then decide to store the data within a cloud storage like SDL for further analysis and retrieval at a future time.

However this is non optimal and introduce unnecessary delays and involvement of unnecessary elements. Also, this known approach requires the active participation of the application servers themselves in storage of the network elements.

Hence, the problem arises that storing data in cloud storages underlies noticeable delays. This is the more relevant and the more noticeable the more devices are trying to access the cloud storages via the application servers. In this regard, it is noted that it is in the nature of the things of the loT concept that there will be plenty of respective devices, such that a significant run on the cloud storages can be expected. Hence, there is a need to provide for optimizations for cloud storage related data flow.

Detailed description of drawings and embodiments of the present invention

The present invention is described herein with reference to particular non-limiting examples and to what are presently considered to be conceivable embodiments of the present invention. A person skilled in the art will appreciate that the invention is by no means limited to these examples, and may be more broadly applied.

It is to be noted that the following description of the present invention and its embodiments mainly refers to specifications being used as non-limiting examples for certain exemplary network configurations and deployments. Namely, the present invention and its embodiments are mainly described in relation to 3GPP specifications being used as non- limiting examples for certain exemplary network configurations and deployments. As such, the description of exemplary embodiments given herein specifically refers to terminology which is directly related thereto. Such terminology is only used in the context of the presented non-limiting examples, and does naturally not limit the invention in any way. Rather, any other communication or communication related system deployment, etc. may also be utilized as long as compliant with the features described herein.

Hereinafter, various embodiments and implementations of the present invention and its aspects or embodiments are described using several variants and/or alternatives. It is generally noted that, according to certain needs and constraints, all of the described variants and/or alternatives may be provided alone or in any conceivable combination (also including combinations of individual features of the various variants and/or alternatives).

According to exemplary embodiments of the present invention, in general terms, there are provided measures and mechanisms for (enabling/realizing) optimizations for cloud storage related data flow.

As discussed above, currently there is no differentiation in the data flow intended for the application and the storage and both tend to take the same approach leading to unnecessary delays.

Figure 8 shows a schematic diagram of an example of a system environment with known signaling variants.

Figure 8 illustrates the current flow of data in the above-mentioned scenario.

In such scenario according to Figure 8, the user equipment (UE) which may e.g. be an loT device having data for the cloud storage (also cloud backend storage, data storage function, shared data layer (SDL)) may be connected to the application server (AS) via an evolved Node B (eNodeB, eNB), a mobility management entity (MME), a service capability exposure function (SCEF), and an application enablement platform (AEP).

Currently, both the intended control data (dashed arrows, control data towards AS) and (payload) data (solid arrows, data towards SDL) flows in the same path towards the SDL and the application server. The data is transmitted via the eNodeB towards the core elements of the network. The AS residing behind the AEP receives the data via the SCEF and then stores the data into the cloud for future use or analysis.

In this procedure, there is unnecessary involvement of lot network elements and the AS itself for the part of the data which is not control information but intended only to be stored and processed within the SDL.

Particularly in the loT scenario, when there are billions of devices sending the data to cloud (like eHealth, smart device, etc.), the mentioned transaction burdens a lot of intermediate network nodes and network functions. Similarly, the same burden is generated when data is pushed from the SDL towards the UE(s).

According to exemplary embodiments of the present invention, the control information from the data intended for the cloud storage (also cloud backend storage, data storage function, shared data layer) is decoupled. This separation allows for the data intended for cloud storage to take more optimized and variant paths towards the storage itself.

This is achieved by introduction of "Data Agents" which may be logical extensions of the cloud storage, i.e. SDL, itself. That is, data agents may be enhanced extension of the SDL which provides the SDL view closer to the device (i.e. lot/ProSe device) itself.

According to exemplary embodiments of the present invention, SDL may introduce layers of the storage at various points like the (loT/ProSe) device itself and in Edge Agents, to ensure that the data is transmitted in a secure and optimized way to the SDL cloud storage.

The major advantage of such approach according to the present invention is that the SDL or cloud storage can be directly available to the device (i.e. UE) via application

programming interfaces (API) which may be standardized.

A basic architecture and data transmission possibilities of this approach according to exemplary embodiments of the present invention is illustrated in Figure 7.

Namely, Figure 7 shows a schematic diagram of an example of a system environment with signaling variants according to exemplary embodiments of the present invention. Figure 7 particularly shows the introduction of new Data Agents according to exemplary embodiments of the present invention.

In Figure 7, a general arrangement of an exemplary UE, an evolved packet core (EPC) which embodies the architecture of the core network of e.g. a Long Term Evolution (LTE) network and allows operation and coordination of several radio networks and thus guarantees mobility, handover and roaming between participants, and the cloud data storage (SDL) is shown. Below, the above-mentioned data agents according to exemplary embodiments of the present invention are described in relation to the arrangement shown in Figure 7.

Here, the Device Data Agent is an enhanced extension of the SDL itself which resides on the device/UE itself and which works with or without local storage. All data that needs to be stored or transmitted by the UE/device is handed over to this agent that ensures that the most optimized path for the data to be stored in the cloud storage is selected. In a mode with local storage the device data agent can also act as a local agent of SDL for reducing latency in particular in time critical services

Further, the Edge Data Agent is an enhanced extension of the SDL which resides on edge elements like e.g. (components of) mobile edge computing (MEC) and which acts as an aggregator towards the cloud storage. The edge data agent also acts as a closer view of the SDL itself so that the latencies involved can be reduced in particular in time critical services.

In this scenario, according to exemplary embodiments of the present invention, the data may flow between the SDL and the Data agents, conventionally from the device (i.e. UE) to SDL, and from SDL to pre-fetch data closer to the device (i.e. UE), namely, either directly onto the device with the Device Data Agent or to the edge elements (e.g. MEC) via the Edge Data Agent.

In Figure 7, four ways for data flow between the device and SDL are shown.

Namely, on the one hand, a User Plane Data Sync is illustrated (arrows hachured diagonally from top left to bottom right). According to this approach, the data transmission utilizes a current user plane method for synchronizing the data with the SDL, i.e., via the EPC towards the SDL.

Further, a Direct Data Sync is illustrated (arrows not hachured). According to this approach, the device (i.e. UE) transfers the data via the device data agent directly to the SDL e.g. using an independent interface like WLAN, Bluetooth, and ZigBee, etc., thereby avoiding/bypassing the complete EPC. This enables a more heterogeneous set of types of devices including e.g. on-cellular WLAN enabled devices to interwork with e.g. vendor storage and loT/ProSe applications. Further, a Control Plane Data Sync is illustrated (arrows hachured horizontally). According to this approach, enhancements for utilization of control plane for transmission of data intended for loT applications may be used. In particular, while according to this approach the data is transferred via the device data agent towards the EPC, the data is redirected to the edge data agent and then transferred directly to the SDL. Particularly, according to exemplary embodiments of the present invention, the data may be routed directly from the MME/ serving GPRS support node (SGSN; GPRS: General Packet Radio Service) as examples for edge elements to the SDL.

Finally, an Edge Plane Data Sync is illustrated (arrows hachured checkered). According to this approach, the data is transferred via the device data agent and the edge data agent directly to the SDL, thereby avoiding/bypassing the complete EPC. In particular, this approach allows for the utilization of the edge data agents to transmit and aggregate the data intended towards SDL.

In the following, exemplary embodiments of the present invention are described in more general terms.

Exemplary embodiments of the present invention are described in more detail in relation to Figures 9 and 10, both showing schematic diagrams of an examples of a system environment with signaling variants according to exemplary embodiments of the present invention.

In particular, while Figure 9 illustrates data flows (solid arrows, data towards SDL) and control information flows (dashed arrows, control data towards AS) in contrast to the respective flows discussed in relation to Figure 8, Figure 10 depicts working of the above introduced data agents.

In contrast to Figure 8 and in line with exemplary embodiments of the present invention as shown in Figure 9, when there are billions of devices (e.g. UEs, loT devices) planning to send data to the cloud storage (like eHealth, smart devices, etc.), the respective device can push the data into the edge SDL, so that the above mentioned transaction (via the core network elements) can be avoided for billions of devices and the data of these billions of devices. Similarly, the same mechanism can be used to push the data to the devices from SDL, where the data was moved to SDL which is located in a central/any other location.

In particular, Figure 8 shows the alternative paths the separated data flow can take to optimize the operations according to exemplary embodiments of the present invention.

One option is for the data flow intended for SDL to take a direct path towards the SDL itself, as already mentioned above. In addition, a second path is for the MME to separate out the SDL intended traffic and directly transfer this data to the SDL to enable direct storage to the SDL.

Both options remove the data flow in unnecessary hops, i.e., the SCEF, AEP and AS itself. Subsequently, the AS can retrieve the data from the SDL directly as required. As mentioned above, according to exemplary embodiments of the present invention, this behavior facilitated by usage of data agents at the device and edge elements. The data agents may be enhanced extensions of the SDL, which provide the SDL view closer to device itself.

According to further exemplary embodiments or the present invention, in case the device cannot have a data agent as explained above, then the next hop may have the data agent to understand and push the data (e.g. via the edge data agent) to the SDL.

According to exemplary embodiments of the present invention, the various data agents (device and edge) act as abstraction points to the SDL (cloud storage) to enhance the transmission experience and latency. This view is also closely augmented by the network optimizations as described above.

In sum, as is derivable from Figure 10, according to exemplary embodiments of the present invention, the device agent may choose the most appropriate mode for data transfer and may define a life time scope and aggregation capability of the data (101 ). The edge agent may aggregate and/or forward the data based on parameters specified by the device agent (102). The cloud storage may push relevant data closer to the device e.g. to enable time critical services (103). The edge agent or cloud storage may choose to prefetch data onto the device itself, if storage exists and is permitted e.g. to enable time critical services (104).

Hence, according to exemplary embodiments of the present invention, virtual zero latency may be provided. The present invention may be implemented by utilization of the data agent configuration at the device or the next hop.

The above-described procedures and functions may be implemented by respective functional elements, processors, or the like, as described below.
