specific Embodiment approach 1

[0040] Embodiment 1: Utilize the dual communication modules of the dual-card dual-standby mobile phone, use one communication module to transmit voice in traditional circuit switched data (CSD) mode, and use another communication module to transmit digital video based on IP packets. After the voice information is processed by the voice communication module of the mobile phone (such as the GSM communication sub-module in the GSM / GPRS communication module, the CDMA communication module, etc.), it is transmitted in CSD mode; after the digital video is compressed, it is transmitted through the data communication module of the mobile phone ( For example, the GPRS communication sub-module in the GSM / GPRS communication module, the CDMA communication module, the TD-SCDMA communication module, etc.), transmit based on the TCP (Transmission Control Protocol, transmission control protocol) / IP network. figure 1 Taking two dual-card dual-standby mobile phones in GSM / GPRS+GSM / GPRS mode as an...

specific Embodiment approach 2

[0041] Embodiment 2: Utilize the dual communication modules of the dual-card dual-standby mobile phone, use one communication module to transmit digital audio based on IP data packets, and use the other communication module to transmit digital video based on IP data packets. Digital audio and video will be compressed separately, through two independent data communication modules of the mobile phone (such as GPRS communication sub-modules in two GSM / GPRS communication modules, GPRS communication sub-modules in a GSM / GPRS communication module and a CDMA Communication module, two CDMA communication modules, etc.), based on TCP / IP network for transmission. figure 2 Taking two dual-card dual-standby mobile phones in GSM / GPRS+GSM / GPRS mode as an example, the second specific implementation mode is analyzed.

[0042] Two communication modules work simultaneously on two channels, enabling real-time, synchronous voice and video communication. The traditional voice communication adopts...

Abstract

The invention discloses a method for realizing a video telephone function on dual-card dual-waiting mobile phones, and includes the following steps: A1), If dual-card dual-waiting mobile phone A is not logged in, the dual-card dual-waiting mobile phone A automatically logs in the server; otherwise, executes step B1; B1), the dual-card dual-waiting mobile phone A calls a dual-card dual-waiting mobile phone B; C1), the dual-card dual-waiting mobile phone B receives the notice; D1), the dual-card dual-waiting mobile phone B responds to the notice, so as to establish real-time communication between the dual-card dual-waiting mobile phone A and the dual-card dual-waiting mobile phone B. The dual-card dual-waiting mobile phone utilizes one communication module to carry out voice communication, and meanwhile uses another communication module to carry out digital video communication, and the two communication modules can realize real-time synchronous operation, and meanwhile carry out simultaneous voice and video communication between two communication parties.

Description

technical field [0001] The invention belongs to a method for realizing a videophone, in particular to a method for realizing a videophone on a dual-card dual-standby mobile phone. Background technique [0002] The dual-card dual-standby mobile phone allows the user to insert two mobile phone cards into the same mobile phone, and both cards can be in the standby and activated state, that is, the two communication modules can communicate at the same time. The dual-card dual-standby mobile phone can be a single-mode mobile phone, such as GSM / GPRS+GSM / GPRS (the existing mobile phone GSM sub-module and GPRS sub-module are generally bound together to form a communication module), CDMA+CDMA, GSM / GPRS GPRS+GSM / GPRS / EDGE mode, etc.; dual-card dual-standby mobile phone can also be a dual-mode mobile phone, such as GSM / GPRS+CDMA, GSM / GPRS+TD-SCDMA mode, etc. [0003] At present, due to the bandwidth limitation of general packet radio service (GRPS, General Packet Radio Service) or cod...
