Method, User Equipment and System for Maintaining a Large Number of Connections
First Claim
1. A method for maintaining a large number of connections, comprising:
- when there is no data transmission between a User Equipment (UE) and a network, a network device deleting a radio bearer and reserving UE context information related to link restoration and a default bearer; and
when data needs to be transmitted between the UE and the network, the network device establishing a bearer connection with the UE according to the reserved UE context information related to link restoration.

Abstract
The present invention provides a method for maintaining a large number of connections. The method comprises: when there is no data transmission between a User Equipment (UE) and a network, a network device deletes a radio bearer and reserves UE context information related to link restoration and a default bearer; when data needs to be transmitted between the UE and the network, the network device establishes a bearer connection with the UE according to the reserved UE context information related to link restoration. At the same time, the present invention provides a UE and system for maintaining a large number of connections. By using the method, the UE and the system of the present invention, a large number of UE connections can be maintained effectively, the network load can be reduced and the connection recovery process can be accelerated.

5. A method for maintaining a large number of connections, comprising:
- when there is no data transmission between a User Equipment (UE) and a network, a network device deleting a radio bearer, and reserving UE context information related to link restoration and a default bearer;
after a fault or a power failure occurs in the network device, discarding all reserved context information of the UE and deleting all bearers, or after the network device initiates a detach process to delete all context information of a large number of UEs and all the bearers because a large amount of UE information is not detected within a specified duration, the method further comprises; when a Machine Type Communication (MTC) server needs to transmit data to a group of the UEs, sending trigger information to the UEs by the network device to establish connections with the UEs. - View Dependent Claims (6, 7, 8)

16. A system for maintaining a large number of connections, comprising a network device, a Machine Type Communication (MTC) server and a User Equipment (UE), wherein
the network device is configured to, when there is no data transmission between the UE and a network, delete a radio bearer and reserve UE context information related to link restoration and a default bearer; -
the MTC server is configured to, when all reserved context information of the UE is lost and all bearers are deleted after a fault or a power failure occurs in the network device, or after the network side initiates a detach process to delete all context information of a large number of UEs and all the bearers because a large amount of UE information is not detected within a specified duration and when data needs to be transmitted to a group of the UEs, send trigger information to the UEs via the network device and establish connections between the MTC server and all the UEs; and the UE is configured to, after receiving the trigger information sent by the MTC server via the network device, establish a connection with the MTC server. - View Dependent Claims (17, 18, 19)
