Abstract
Embodiments of this application disclose a communication method and a related apparatus. The method includes: A UDM receives a plurality of authentication vector obtaining request messages from one or more AUSFs for same UE, where the plurality of authentication vector obtaining request messages are for obtaining authentication vectors corresponding to the UE; and the UDM sequentially processes the plurality of authentication vector obtaining request messages, to avoid a problem that subsequently an intermediate key Kausf stored on the UE and an intermediate key Kausf stored on a network device side are out of synchronization because the UE receives a plurality of NAS SMC messages or EAP-Success messages whose receiving time sequence is uncontrollable.
Claims20
A communication method, comprising:
- receiving, by a terminal device, a first authentication request message from a first access and mobility management function entity in a first communication network and a second authentication request message from a second access and mobility management function entity in a second communication network;
- and
- sequentially processing, by the terminal device, the first authentication request message and the second authentication request message.
A communication apparatus comprising a processor and a memory, wherein the processor is coupled to the memory, and the memory stores instructions which, when executed by the processor, cause the processor to:
- receive a first authentication vector obtaining request messages from a first authentication server function, wherein the first authentication vector obtaining request messages is for obtaining an authentication vector corresponding to a terminal device;
- receive a second authentication vector obtaining request message from a second authentication server function, wherein the second authentication vector obtaining request message is for obtaining an authentication vector corresponding to the terminal device;
- and
- sequentially process the first authentication vector obtaining request message and the second authentication vector obtaining request message.
