Abstract
Provided are an indication information sending method, apparatus and system, a storage medium, and an electronic device, where the indication information sending method includes: sending, by a first access and mobility management function (AMF), first indication information to a first target network element, where the first indication information is used for indicating whether a packet data unit (PDU) session is capable of interworking with a target network system.
Claims20
An indication information sending method, comprising:
- sending, by a first access and mobility management function (AMF), first indication information to a unified data management (UDM) directly;
- and
- causing, via the first indication information, the UDM to store data network name (DNN) interworking information, the DNN interworking information being associated with a data session of a UE interworking between accessing at least two different wireless systems and comprising:
- DNN information and at least one of an address of a session management function (SMF) or a packet data unit (PDU) gateway (PGW), wherein the SMF or the PGW in the DNN interworking information is selected as only one SMF or PGW for interworking between the at least two different wireless systems among a plurality of SMFs or PGWs associated with the DNN so that when the UE moves from a first wireless system to a second wireless system of the at least two different wireless systems, the second wireless system uses the selected one SMF or PGW for each DNN to maintain continuity of a session between the first wireless system and the second wireless system.
An electronic apparatus, comprising at least one memory and at least one processor, wherein the at least one memory is configured to store a computer program, and the at least one processor is configured to execute the computer program to perform steps comprising:
- sending, by a first access and mobility management function (AMF), first indication information to a unified data management (UDM) directly;
- and
- causing, via the first indication information, the UDM to store data network name (DNN) interworking information, the DNN interworking information being associated with a data session of a UE interworking between accessing at least two different wireless systems and comprising:
- DNN information and at least one of an address of a session management function (SMF) or a packet data unit (PDU) gateway (PGW), wherein the SMF or the PGW in the DNN interworking information is selected as only one SMF or PGW for interworking between the at least two different wireless systems among a plurality of SMFs or PGWs associated with the DNN so that when the UE moves from a first wireless system to a second wireless system of the at least two different wireless systems, the second wireless system uses the selected one SMF or PGW for DNN to maintain continuity of a session between the first wireless system and the second wireless system.
