Abstract
The embodiments of the present disclosure relate to the technical field of network communications. Provided is a session establishment method applied to an access network device, comprising: receiving a session request of a UE, and sending the session request to a core network device; receiving a request response message returned by the core network device, wherein the request response message carries a session resource; initiating security activation of an access stratum to the UE; and after it is confirmed that the security activation is successful, sending the session resource to the UE for the UE to establish a session based on the session resource.
Claims14
A session establishment method, applied to an access network device, comprising:
- receiving a session request of a user equipment (UE), and sending the session request to a core network device;
- receiving a request response message returned by the core network device;
- wherein the request response message carries a session resource and a security key, and the session resource comprises an IP address allocated by the core network device to the UE and a Session Management Function (SMF) selected by the core network device for the UE;
- extracting the session resource from the request response message, and storing the extracted session resource in a cache area;
- extracting the security key from the request response message, and initiating security activation of an access stratum to the UE based on the security key;
- and
- after confirming that the security activation is successful, sending the session resource stored in the cache area to the UE so that the UE establishes a session based on the session resource;
- wherein initiating security activation of an access stratum to the UE comprises:
- configuring a Data Radio Bearer (DRB) for the session and performing negotiation of access stratum security parameters.
A session establishment apparatus, comprising:
- a request receiving module, configured to receive a session request from a user equipment (UE);
- a forwarding module, configured to send the session request to a core network device;
- a response receiving module, configured to receive a request response message returned by the core network device;
- wherein the request response message carries a session resource and a security key, and the session resource comprises an IP address allocated by the core network device to the UE and a Session Management Function (SMF) selected by the core network device for the UE;
- a security activation module, configured to extract the session resource from the request response message, store the extracted session resource in a cache area, extract the security key from the request response message, and initiate a security activation of an access stratum to the UE based on the security key;
- and
- a sending module, configured to send the session resources stored in the cache area to the UE after confirming that the security activation is successful, so that the UE establishes a session based on the session resource;
- wherein the security activation module is further configured to configure a Data Radio Bearer (DRB) for the session and perform negotiation of access stratum security parameters.
