Method for transmitting/responding paging information for dual-mode access terminal and device and method for network switching according to network indication

A device for switching between two networks according to network indications comprising:

• a control module which is adapted to analyzes the network switching indication received through current access network and control switch operation between a CDMA2000 modem and a HRPD modem;
• a keyboard which includes a key “accept” which is adopted to accept an network switching indication received through current access network and a key “reject” which is adopted to reject the network switching indication received through current access network;
• a CDMA2000 modem which is adapted to perform encoding and decoding of service data, encoding and decoding of signaling, spectrum spreading and de-spreading of physical channel, and modulating and demodulating;
• a HRPD modem which is adapted to perform encoding and decoding of service data, encoding and decoding of signaling, spectrum spreading and de-spreading of physical channel, and modulating and demodulating;
• a memory which is adapted to save data necessary for normal operation of the MS/AT;
• a switching unit which is adapted to connect a radio module with the CDMA2000 modem or the HRPD modem respectively under control of a signal from the control module;
• and
• a radio module which is adapted to connect with the modems through the switching unit, perform conversion between baseband digital signals and RF analog signals and receive and transmit the RF analog signals through an antenna.

A method for switching between two networks according to network indications comprising steps of:

• after receive an network switching indication through a current access network, a control module of a dual mode MS/AT analyzing the indication and displaying relevant information to a user;
• if the user depress key “accept”, the control module disabling the control module's control part related to current network and a modem corresponding to current network;
• and
• enabling the control module's control part related to the other network and a modem corresponding to the other network.
• if the user depress key “reject”, the dual-mode MS/AT continuing to use the control module's control part related to current network and the modem corresponding to current network.
