sending, from the communication processor, a second request to a network device, wherein the second request comprises a request for establishing a session, and the second request comprises the at least one parameter of the route selection descriptor.
9 . The method according to claim 8 , wherein the first parameter is the same as a parameter comprised in a traffic descriptor in the URSP rule.
10 . The method according to claim 8 , wherein the first parameter comprises at least one of the following parameters:
a destination address parameter of to-be-transmitted data;
a data network parameter corresponding to the to-be-transmitted data;
an application descriptor corresponding to the to-be-transmitted data; or
a connection capability parameter corresponding to the to-be-transmitted data.
11 . The method according to claim 9 , wherein the traffic descriptor comprises at least one of the following parameters:
a destination address parameter;
a data network parameter;
an application descriptor; or
a connection capability parameter.
12 . The method according to claim 8 , wherein the at least one parameter of the at least one route selection descriptor comprises:
a parameter of a network slice;
a data network name (DNN); or
a session type.
13 . The method according to claim 8 , wherein the first AT command comprises at least one of the following:
