Ue assisted paging enhancements for multi-usim devices

Various communication systems may implement network management tools to help manage registration requests from a user equipment. For example, network functions in a communication system with a shared data layer may be used to manage requests from the user equipment. A method may include transmitting a request from a user equipment to a network function. The method may also include receiving at the user equipment a temporary identification from the network function The temporary identification comprises an identifier that helps locate a shared data layer function that stores context information for the user equipment. In addition, the method may include transmitting from the user equipment a subsequent request comprising the temporary identification to another network function or the network function.

Network selection with stateless network functions

In accordance with example embodiments of the invention there is at least a method and apparatus to perform receiving from a network device, by a network node of a communication network, information regarding a secondary packet data unit session request for pairing the secondary packet data unit session with a primary packet data unit session, wherein information comprises an indication of at least one of the packet data unit session pair, a required quality of service or a required redundancy level for the secondary packet data unit session; based on the information, establishing the secondary packet data unit session; based on the establishing, sending towards the network device an indication of the secondary packet data unit session being established; storing the information regarding the secondary packet data unit session request; and forwarding at least part of the information regarding the secondary packet data unit session request to at least one target node during mobility procedure.

Enhanced mobility for URLLC services and redundant PDU sessions

In some example embodiments, there may be provided a method that includes receiving, at a user equipment while being served by a first system and during protocol data unit session establishment or modification procedure, a message including an access point name aggregate maximum bit rate value; and when there is an inter-system change from the first system to the second system, setting, at the user equipment, the access point name aggregate maximum bit rate value of a session management context for the second system to the received access point name aggregate maximum bit rate value received while being served by the first system. Related systems, methods, and articles of manufacture are also described.

Session context conversion

A plurality of interworking functions, which provide interworking between a communication network acting as an access network and a non-public network, is associated with a plurality of sites or network slices hosted by the non-public network (S). A user equipment is configured to select an interworking function of the plurality of interworking functions based on information on a site or network slice the user equipment is associated with, of the plurality of sites or network slices (S).

Non-3GPP interworking function (N3IWF) selection for stand-alone non-public networks (SNPN)

There is provided an apparatus comprising means for: receiving, from a requesting service and/or from a network function, an indication of security credentials for a selected service agent; and transmitting the security credentials to the selected service agent as part of a service request from the requesting service.

Communication system

A method, apparatus, and computer program product provide for adaptive paging for user equipment (UE) with multiple subscriber identification modules (SIMs). A UE may provide, in a registration message to the network, an indication that the UE supports multiple SIMs. The network may allow repeated paging to let a SIM miss a paging occasion without interpreting that the UE is unavailable. The indication from the UE can specify the number of SIMS supported by the UE. The network can adapt the number of paging repetitions to the UE. If the UE is accepting paging from another network or has a SIM that is already active with the network, the UE sends the network a paging control message. If the UE detects a paging occasion conflict, the UE sends the network a registration message with a replacement ID for paging another SIM, and the UE and the network negotiate appropriate paging.
