Problems solved by technology

It takes about 15 seconds to complete the above-mentioned data service to voice switching on the WINCE4.0 operating system, which leads to too long waiting time for incoming calls, and even causes the other party to think that no one answers and interrupts the incoming call, causing inconvenience to the user

Embodiment Construction

[0010] A preferred embodiment of the present invention will be further described below.

[0011] For the flow chart of a preferred embodiment of the terminal handover method of voice short message priority in a kind of CDMA network data transmission process of the present invention, take CDMA mobile phone as example explanation, figure 1 The flow chart of establishing data transmission service and responding voice or short message priority service by mobile phone CDMA module, mobile phone operating system and CDMA network is given. It should be noted that this process is mainly described for the CDMA module of the mobile phone, the operating system of the mobile phone and the control process of the CDMA network. Other processes unrelated to the control process should be clear to those skilled in the art, so no detailed description will be given.

[0012] First, when the mobile phone dials through the CDMA network, it requests data services;

[0013] Step a1: The mobile phone ...

Abstract

The invention discloses a terminal switching method for a voice short message with priority in a code division multiple access (CDMA) network data transmission process. The terminal switching method comprises the following steps that: when a mobile terminal receives an incoming call or a short message in the data transmission process, the data carrier detection (DCD) signal of a terminal operating system is set to be invalid, so that the operating system judges that data transmission connection with the CDMA network is disconnected, immediately stops data transmission and enters voice talking or short message communication connection; and simultaneously, the data terminal ready (DTR) signal level of a terminal CDMA module is increased first and then reduced, so that the terminal CDMA module judges that data transmission is finished, interrupts the current data transmission service, and automatically enters the voice talking or short message service with priority. By the terminal switching method disclosed by the invention, the flow for realizing response to the voice or short message service with priority when the mobile terminal performs data transmission in the CDMA network is simpler, the flow processing speed is increased, and the response time of the mobile terminal is shortened.

Description

technical field [0001] The invention relates to the technical field of CDMA communication, in particular to a technical solution for terminal switching of data service and voice service in the field of CDMA communication. Background technique [0002] In the mobile communication network adopting CDMA (Code Division Multiple Access, code division multiple access) system, for users, voice and data services are the two basic services of CDMA2000 1X, but in CDMA2000 1X Release0 version, for users You cannot have both: you cannot use data services while making voice calls; you cannot perform voice communication while using data services. During the actual commercial use of CDMA2000 1X Release 0, some operators proposed the requirement of VPOP, that is, pseudo-concurrent voice and data services to ensure that a user can receive a call from another user when using data services, but this is not true concurrent business. However, the CDMA2000 1X Release A system realizes concurren...
