After time reaches, established PDU session is deleted, and establishes new PDU session；Wherein, the entry-into-force time is to come into force
Or it comes into force in terminal idle state.
However in specific implement, PCF entity is sent to terminal to be used to indicate immediately or deletes in terminal idle state
The PDU session of foundation and when establishing the instruction information of new PDU session, first can be sent to AMF entity for instruction information, by AMF
Entity command information is sent to base station, and base station is sent to terminal after receiving instruction information, then by instruction information.Therefore, originally
Inventive embodiments provide a kind of system diagram that terminal routing strategy updates, referring specifically to shown in Fig. 2.
In embodiments of the present invention, since PCF entity is after determining that terminal needs to update URSP, it can send and use to terminal
Immediately or established PDU session is deleted in terminal idle state and establish the instruction information of new PDU session, and meeting in instruction
Established PDU session is deleted according to the time in instruction information and establishes new PDU session, ensure that network side and terminal pair
In when deleting established PDU session and establish time of new PDU session and be consistent, and after the PDU session of update
It will use the URSP of update, it is possible to guarantee that network side and terminal enable the PDU of update for when and be consistent, to drop
Low there is the probability that upstream data can not be routed normally.The method updated below to terminal routing strategy is situated between in detail
It continues.
PCF entity determines that terminal needs to update URSP, and wherein PCF entity can be according to carrier policy or other factors
