receiving a bearer setup request message or a bearer modify request message from the core-network network element, wherein the bearer setup request message or the bearer modify request message carries service indication information for indicating a priority of the service; and

determining, according to the priority which is of the service and indicated by the service indication information carried in the bearer setup request message or the bearer modify request message and the device type of the UE, whether to execute a bearer processing operation corresponding to the bearer setup request message or the bearer modify request message.

5. A service control method for a machine type communications device comprising:

receiving, by a target-access-network network element, a handover request message from a source-access-network network element, wherein the handover request message carries device type indication information of a UE, and wherein the device type indication information of the UE is used to indicate whether the UE is a machine type communications device;

determining a device type of the UE according to the device type indication information of the UE; and

determining, according to the device type of the UE, whether to execute a handover operation corresponding to the handover request message when a current load of the target-access-network network element exceeds a set threshold.

6. The method according to claim 5 , wherein the handover request message also carries service indication information for indicating a priority of the service, and wherein determining, according to the device type of the UE, whether to execute a handover operation corresponding to the handover request message comprises determining, according to the priority which is of the service and indicated by the service indication information carried in the handover request message and the device type of the UE, whether to execute the handover operation corresponding to the handover request message.

7. An access-network network element comprising:

a first receiving unit configured to receive a service request message from a core-network network element, wherein the service request message carries device type indication information of a UE, and wherein the device type indication information of the UE is used to indicate whether the UE is a machine type communications device;

a first determining unit configured to determine a device type of the UE according to the device type indication information of the UE; and

a first service controlling unit configured to determine, according to the device type of the UE, whether to execute a service operation corresponding to the service request message when a current load of the access-network network element exceeds a set threshold.

8. The access-network network element according to claim 7 , wherein if the service request message also carries service indication information for indicating a priority of the service, the first service controlling unit is specifically configured to determine, according to the priority which is of the service and indicated by the service indication information carried in the service request message and the device type of the UE, whether to execute the service operation corresponding to the service request message when the current load of the access-network network element exceeds the set threshold.

9. An access-network network element comprising:

a second receiving unit configured to receive a handover request message from a source-access-network network element, wherein the handover request message carries device type indication information of a UE, and wherein the device type indication information of the UE is used to indicate whether the UE is a machine type communications device;

a second determining module configured to determine a device type of the UE according to the device type indication information of the UE; and

a second service controlling unit configured to determine, according to the device type of the UE, whether to execute a handover operation corresponding to the handover request message when a current load of the access-network network element exceeds a set threshold.

10. The access-network network element according to claim 9 , wherein the handover request message also carries service indication information for indicating a priority of the service, and wherein the second service controlling unit is specifically configured to determine, according to the priority which is of the service and indicated by the service indication information carried in the service request message and the device type of the UE, whether to execute the handover operation corresponding to the handover request message when the current load of the access-network network element exceeds the set threshold.

11. A service control system comprising:

a core-network network element; and

an access-network network element,

wherein the access-network network element is configured to:
