Method and device for selecting long term evolution lte network

A method for selecting a Long Term Evolution (LTE) network, comprising:

• receiving, by an LTE base station, a connection establishment request message sent by a UE when a Circuit Switched Fallback (CSFB) service ends, wherein, the connection establishment request message comprises an identity of the UE;
• and
• selecting, by the LTE base station, in accordance with the identity of the UE and identity information of an LTE Public Land Mobile Network (PLMN) registered when the UE initiates the CSFB service, the LTE PLMN corresponding to the identity information of the LTE PLMN.

A 2nd generation/3rd generation (2G/3G) base station, providing service for a Circuit Switched Fallback (CSFB) service, comprising:

• a receiver device, configured to receive a connection release message sent by a serving Mobile Switching Centre/Visitors Location Register (MSC/VLR), wherein, the connection release message comprises identity information of an LTE Public Land Mobile Network (PLMN) registered when a user equipment UE initiates a CSFB service;
• a processor device, configured to select, according to the identity information of the LTE PLMN which is received by the receiver device, target frequency band information, wherein, the target frequency band information is used for indicating the UE to select a cell for residing on a frequency band corresponding to the target frequency band information;
• a transmitter device, configured to send the target frequency band information selected by the processor device to the UE.

A Long Term Evolution (LTE) base station, comprising:

• a receiver device, configured to receive a connection establishment request message sent by a user equipment (UE) when a Circuit Switched Fallback (CSFB) service ends, wherein, the connection establishment request message comprises an identity of the UE;
• and
• a processor device, configured to select, according to the identity of the UE and identity information of the LTE Public Land Mobile Network (PLMN) registered when the UE initiates the CSFB service, the LTE PLMN corresponding to the identity information of the LTE PLMN.
