         5 . The radio bearer processing method according to  claim 1 , wherein the SRB is a SRB3. 
     
     
         6 . A network device, comprising a memory, a processor, and a computer program stored in the memory and executed by the processor, wherein the processor is configured to execute the computer program so as to implement a radio bearer processing method, comprising:
 releasing or refusing to release, when a second event is detected, a signaling radio bearer (SRB) from a mobile terminal,   wherein the second event comprises at least one of: the secondary network device being released by a master network device accessed by the mobile terminal, configuration of the secondary network device being changed, and the mobile terminal being switched from the secondary network device to another secondary network device.   
     
     
         7 . The network device according to  claim 6 , wherein the releasing the SRB from a mobile terminal comprises:
 receiving second information from the master network device, the another secondary network device, the mobile terminal, the mobile terminal through the master network device or the another secondary network device, the second information being used to instruct or request the secondary network device to release the SRB from the mobile terminal; and   releasing the SRB from the mobile terminal based on the second information.   
     
     
         8 . The network device according to  claim 6 , wherein after the releasing the SRB from the mobile terminal, the radio bearer processing method further comprises:
 transmitting third instruction information for indicating that the SRB has been released to the master network device or the another secondary network device.   
     
     
         9 . The network device according to  claim 6 , wherein after the releasing the SRB from the mobile terminal, the radio bearer processing method further comprises:
 transmitting configuration information of an RRC message to the mobile terminal,   wherein the configuration information is used to indicate: an RRC message that needs to be reported by the mobile terminal to the master network device; or an RRC messages that needs to be discarded by the mobile terminal.   
     
     
         10 . The network device according to  claim 6 , wherein the SRB comprises a SRB3 used to transmit RRC messages Related to the secondary network device. 
     
     
         11 . A non-transitory computer-readable storage medium storing therein a computer program, wherein the computer program is executed by a processor so as to implement a radio bearer processing method, comprising
 releasing or refusing to release, when a second event is detected, a signaling radio bearer (SRB) from a mobile terminal,   wherein the second event comprises at least one of: the secondary network device being released by a master network device accessed by the mobile terminal, configuration of the secondary network device being changed, and the mobile terminal being switched from the secondary network device to another secondary network device.   
     
     
         12 . The non-transitory computer-readable storage medium according to  claim 11 , wherein the releasing the SRB from a mobile terminal comprises:
 receiving second information from the master network device, another secondary network device, the mobile terminal, the mobile terminal through the master network device or the another secondary network device, the second information being used to instruct or request the secondary network device to release the SRB from the mobile terminal; and   releasing the SRB from the mobile terminal based on the second information.   
     
     
         13 . The non-transitory computer-readable storage medium according to  claim 11 , wherein after the releasing the SRB from the mobile terminal, the radio bearer processing method further comprises:
