Claim 5:
6. A service transmission apparatus, comprising:
a memory to store a computer program; and
a processor coupled to the memory, wherein when the computer program is executed by the processor, cause the apparatus to:
receive user identifier information of a terminal device from a secondary base station using a master base station; or
send the user identifier information to the secondary base station using the master base station, wherein the user identifier information is used by the secondary base station to determine an association between the user identifier information and a radio bearer;
determine that a master base station is not capable of continuing to provide a service for a terminal device; and

send a mobility management context of the terminal device to the secondary base station, wherein the mobility management context includes at least one of an area restriction, an access technology restriction, or a security context, and wherein the mobility management context is used by the secondary base station to perform mobility management on the terminal device, wherein the apparatus is further to:
send the mobility management context and the user identifier information of the terminal device to the secondary base station, wherein the user identifier information is used to instruct the secondary base station to associate the mobility management context with the radio bearer between the terminal device and the secondary base station.
