Abstract
Provided is a method for transmitting 1x paging information through an HRPD network and responding to the 1x paging information by a dual-mode MS/AT. After the MS/AT turns to an HRPD network and informs an MSC of related information, if some 1x paging information arrives, the MSC sends a message indicating 1x service arrival to the PCF. An HRPD AN bears the 1x service arrival message that carries calling information sent from the PCF in the 1x service packet to send to the MS/AT. If the user, receiving the 1x service arrival message, chooses to accept a 1x call, the MS/AT terminates the service in the HRPD network and turns to the 1x network to send a “paging response” message to a 1x BS.
Claims12
A device for switching between two networks according to network indications comprising:
- a control module, configured to analyze a network switching indication, received through a current access network and control a switch operation between a Code Division Multiple Access 2000 1x (CDMA2000) modem and a High Rate Packet Data (HRPD) modem;
- a keyboard, including an “accept” key, which is configured to accept the network switching indication received through the current access network and a “reject” key, which is configured to reject the network switching indication received through the current access network;
- a CDMA2000 modem, configured to perform encoding and decoding of service data, encoding and decoding of signaling, spectrum spreading and de-spreading of a physical channel, and modulating and demodulating;
- a HRPD modem, configured to perform encoding and decoding of service data, encoding and decoding of signaling, spectrum spreading and de-spreading of the physical channel, and modulating and demodulating;
- a memory, configured to save data necessary for normal operation of a dual-mode Access Terminal (MS/AT);
- a switching unit, configured to connect a radio module with the CDMA2000 modem or the HRPD modem under control of a signal from the control module;
- and
- a radio module, configured to connect with the modems through the switching unit, perform conversion between baseband digital signals and Radio Frequency (RF) analog signals and receive and transmit the RF analog signals through an antenna,
- wherein the MS/AT receives a 1x call arrival message from a Mobile Switching Center (MSC) and the MSC starts a timing clock while sending the 1x call arrival message to a Packet Control Function (PCF), the timing clock is divided into a first clock and a second clock, the first clock stops after the MSC receives a 1x call response message from the MS/AT through an HRPD network and the second clock stops after the MSC receives a 1x call rejection message through the HRPD network.
A method for switching between two networks according to network indications comprising steps of:
- after receiving a network switching indication through a current access network, a control module of a dual mode Access Terminal (MS/AT) analyzes the indication and displays relevant information to a user to control a switch operation between a Code Division Multiple Access 2000 1x (CDMA2000) modem and a High Rate Packet Data (HRPD) modem;
- if the user depresses an “accept” key, the control module disables the control module's control part related to the current network and a modem corresponding to the current network;
- and
- if the user depresses a “reject” key, the control module disables the control module's control part related to the second network and a modem corresponding to the second network and the dual-mode MS/AT continues to use the control module's control part related to the current network and the modem corresponding to the current network, wherein the MS/AT receives a 1x call arrival message from a Mobile Switching Center (MSC) and the MSC starts a timing clock while sending the 1x call arrival message to a Packet Control Function (PCF), the timing clock is divided into a first clock and a second clock, the first clock stops after the MSC receives a 1x call response message from the MS/AT through an HRPD network and the second clock stops after the MSC receives a 1x call rejection message through the HRPD network.
