Description

METHOD AND APPARATUS FOR HANDLING VAL SERVICE AREA CONFIGURATION IN SEAL IN A WIRELESS COMMUNICATION SYSTEM

[0001] This application is based on and derives the benefit of Indian Provisional Application 202341011372, the contents of which are incorporated herein by reference.

[0002] The present disclosure relates generallyto wireless communication networks, and more particularly relates to a method and apparatus for handling Vertical Application Layer (VAL) service area configuration in a Service Enabler Architecture Layer (SEAL).

[0003] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz (THz) bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0004] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0005] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0006] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0007] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0008] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

[0009] Currently, VAL servers share a geographical area with SEAL servers for following requests. For example, the requests can comprise:

[0010] Get UE Information request from a VAL server to a SEAL Location Management (LM) server to get a list of UEs in a particular geographical area,

[0011] Location area monitoring subscription request from the VAL server to a SEAL LM to get a list of User Equipment's (UEs) as and when they move in or out of a particular location, and

[0012] Location based group creation request from the VAL server to a SEAL Group Management (GM) server to create a group with the list of UEs in a particular geographical area.

[0013] In all the above cases, the VAL server can share a VAL service area identifier (ID) as attribute instead of sharing geographical co-ordinates. The SEAL LM maintains the mapping of VAL service Area Identifier and the corresponding geographical co-ordinates. The VAL server can use the VAL service area ID when consuming the services from other SEAL server like group management server. When the SEAL GM server receives any request from the VAL service containing the VAL service area ID, it needs to get the corresponding geographical co-ordinates from the SEAL LM. Also, whenever the VAL server updates a configured VAL service area ID, add the VAL service Area ID or delete the VAL service Area ID, mapping the other SEAL services needs to be notified of these updates.

[0014] Currently there is no mechanism of how other SEAL servers, other than SEAL Location Management server, gets the details of the VAL service area ID, how they are notified of the updates to the configured VAL service area IDs.

[0015] The above information is presented as background information only to help the reader to understand the present invention. Applicants have made no determination and make no assertion as to whether any of the above might be applicable as prior art with regard to the present application.

[0016] An embodiment provides a method for a location management server in a wireless network. The method includes receiving, from a service enabler architecture layer (SEAL) server, a vertical application layer (VAL) service area subscription request message; and in case that the SEAL server is authorized to subscribe at least one update for at least one VAL service area identifier (ID), transmitting, to the SEAL server, a VAL service area subscription response message.

[0017] An embodiment provides a method for handling a VAL service area configuration in a wireless network. The method includes sending, by a SEAL server, a VAL service area subscription request to a location management server to get notified of at least one change with respect to a VAL service area configuration.

[0068] Definition:

[0069] Vertical Application Layer (VAL) server: a generic name for a server application function of a specific VAL service.

[0070] Service Enabler Architecture Layer (SEAL) service: a generic name for a common service (e.g. group management, configuration management, location management) that can be utilized by multiple vertical applications.

[0071] Embodiments herein propose a wireless network and method for handling a VAL service area configuration in a wireless network. The method includes sending, by a SEAL server, a VAL service area subscription request to a location management server to get notified of at least one change with respect to a VAL service area configuration. The request message includes at least one of: at least one VAL service area identifier and a notification target URI. Further, the method includes receiving, by the SEAL server, a VAL service area subscription response from the location management server based on the VAL service area subscription request, when the SEAL server is authorized to subscribe to at least one update for the VAL service area identifier. The VAL service area subscription response includes a subscription status indicating a subscription result associated with the VAL service area subscription request.

[0072] The VAL service area is configured at the Location management server and is assigned with unique identifier. This configuration is not known to other SEAL servers since the VAL servers can use the VAL service area ID in the requests to other SEAL servers and they cannot infer what is the geographical coordinates associated with VAL service area ID. Through the steps proposed in this invention, the SEAL servers can subscribe to the VAL service area ID related changes to the location management server.

[0073] Referring now to the drawings, and more particularly to FIGS. 1 through 9, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.

[0074] Embodiments herein propose a wireless network and a method to provide procedures for SEAL servers to query the VAL service area IDs and subscribe to changes made for the VAL service area IDs configured at the SEAL LM server. The SEAL servers (100) can be any of the SEAL servers (100) defined in the 3GPP specification technical specification (TS) 23.434.

[0075] A VAL service area refers to a geographical area served by a VAL server. The VAL server may have more than one VAL service area defined. These VAL service areas are configured by the VAL server to a location management server (200) and are assigned with unique identifiers. During the VAL service area configurations in place, the VAL server may use a VAL service area ID as part of the location information in a SEAL application programming interfaces (APIs) requiring location information. These configurations can be updated by the VAL server in order to modify the geographical area associated with the VAL service area ID and the SEAL server can internally manage the updates without requiring the VAL server to re-invoke the APIs where the updated VAL service area IDs are being used.

[0076] In an embodiment, the VAL service area obtain request can be used by other SEAL servers to the SEAL LM server to obtain the list of VAL service area identifiers and the corresponding geographical locations configured at the SEAL LM server. For example, a SEAL Group Management (GM) server can use this request to obtain the list of VAL service area identifiers configured at the SEAL LM server or to query the geographical location mappings of one or more VAL service area identifiers.

[0077] Table 1 specifies the information flow VAL service area obtain request from SEAL servers (100) to the SEAL LM server.

[0078] Information elementStatusDescriptionIdentityM (Mandatory)Indicates the SEAL server identity.VAL service area IDsO (Optional)Indicates the list of the requested VAL service area identifiers. If this information element is not provided, the SEAL server requests all available VAL service area identifiers for the SEAL server.VAL Service IDMIdentity of the VAL service for which the VAL service area configuration is requested

[0079] Table 2 specifies the information flow VAL service area obtain response from the SEAL LM server in response to the above VAL service area obtain request.

[0081] FIG. 1 depicts a procedure for the VAL service area obtain request while handling the VAL service area configuration in the wireless network (1000). As depicted in step 1, the SEAL server (100) (e.g. Group Management server or the like) sends the VAL service area obtain request to the location management server (200) to retrieve the available VAL service area identifiers. In the request message, the SEAL server (100) includes the information as specified in the Table 1. As depicted in step 2, the location management server (200) shall check if the SEAL server (100) is authorized to initiate VAL service area obtain request. As depicted in step 3, if the SEAL server (100) is authorized to obtain the VAL service area identifiers, the location management server (200) sends the VAL service area obtain response. In the response, the SEAL location management server (200) includes the information as specified in Table 2.

[0082] In an embodiment, the VAL service area obtain request can be used by the other SEAL servers to request the SEAL LM server to get the updates or notified about the VAL service area identifiers updates. For example, the SEAL group management server can use this request to get notified if any changes are made to the VAL service area IDs or if any new VAL service area IDs are configured or if any VAL service area IDs are deleted.
