3GPP Rel-13 Interworking discussions Group Name: TP #18 Source: Rejesh Bhalla, ZTE Corporation, rabhalla@ztetx.com Meeting Date: 2015-07-21 Agenda Item: TBD

Background Information Incoming LS from 3GPP SA2 TP-2015-0732 Incoming LS from OMA ARC WG TP-2015-0749 oneM2M WI #0037: 3GPP Rel-13 Interworking TP-2015-0694R02

Incoming LS from 3GPP SA2 Incoming LS from 3GPP SA2 informs about work done during Rel-13 on MTC features: Features that allow an application to take advantage of the service capabilities provided by the 3GPP system AESE, MONTE, GROUPE and HLCom features 3GPP TS 23.682 (version 13.2.0 or later) includes Stage-2 aspects for these features. Stage-3 work will be progressed by 3GPP CT WGs LS is addressed to GSMA, OMA and oneM2M

3GPP AESE Feature Architecture Enhancements for Service capability Exposure Service Capability Exposure Function (SCEF) entity provides a means to expose the services and capabilities provided via 3GPP interfaces Specifically, solutions have been provided for the following: Support for setting up an AS session with required QoS Support for changing the chargeable party at session set-up or during the session Support of 3rd party interaction on information for predictable communication patterns Support for informing a 3rd party about potential network issues Support for 3GPP resource management for background data transfer

3GPP MONTE and HLCom features Monitoring Enhancements (MONTE) Monitoring of specific events in the 3GPP system and making such monitoring events information available via the SCEF High Latency Communication (HLCom) Solution for downlink access for devices that are not reachable for a long period e.g. due to device applying Power Saving techniques

3GPP GROUPE feature Group based Enhancements (GROUPE) Solutions for group level NAS congestion control (internal 3GPP function – no action by oneM2M) Solutions for message delivery for a group of devices using MBMS SCS/AS uses an API to the SCEF to access MBMS services

3GPP architecture for Service Capability Exposure

Possible areas of focus SCEF internal architecture and APIs to expose 3GPP service capabilities via SCEF have NOT been specified by SA2 3GPP SA2 has defined some expected behaviour of SCEF though SA2 has invited GSMA, OMA and oneM2M to consider the creation of APIs The need to define and specify SCEF internal capabilities also for using the APIs

3GPP architecture for Service Capability Exposure Areas of Focus Target SDOs

Incoming LS from OMA ARC WG Incoming LS from OMA ARC WG informs about a new work item (ENCap-M2M) regarding Network APIs that would expose network capabilities to oneM2M and other applications APIs (and SCEF) per 3GPP requirements

oneM2M Work Item oneM2M Work Item # 0037: 3GPP_Rel13 Interworking Objective: To produce an interworking specification between oneM2M architecture and 3GPP Rel-13 architecture for Service Capability Exposure defined in TS 23.682 Different deployment scenarios such as SCEF hosted by MNO, hosted by oneM2M Service Provider or hosted by a 3rd party service provider to be considered IN-CSE provides SCEF functionality and interfaces directly with the 3GPP network (Arch Option 1) Addresses scenario when SCEF is hosted by trusted oneM2M service provider IN-CSE interfaces with the SCEF using OMA defined other APIs (Arch Option 2) Addresses scenario of SCEF hosted by MNO or by a trusted 3rd party service provider

Scope of work ... Architecture framework IN-CSE: Support for all deployment scenarios Support for relevant OMA specified APIs Support for other APIs Access control IN-CSE: Arch Option 1: Southbound interfaces: 3GPP exposed interfaces. Possible input to 3GPP. Northbound interfaces: TBD. Arch Option 2: Southbound interfaces: OMA specified or other APIs. Possible input to OMA for other APIs. Northbound interfaces: TBD Other exposure function: For supporting other APIs (Arch Opt 2), Southbound interfaces: 3GPP exposed interfaces or other underlying network exposed interfaces. Northbound interfaces: other APIs.

Scope of work .. Identify use cases related to AESE, MONTE, GROUPE and HLCom features as in 3GPP TR 23.682 that need to be supported by oneM2M Each such use case identified as a ‘Key Issue’ Leverage solution guidelines in 3GPP TS 23.682 for developing oneM2M specific solution(s) for each Key Issue For agreed solution(s), progress normative work Identify other use cases for service exposure from 3GPP network (timeline TDB) Develop solution(s) for each such Key Issue
