Wireless communication terminal, method and system

Abstract

The invention discloses a wireless communication terminal, comprising: a first communication module which is used for building a speech communication link with a called terminal, carrying out the speech communication with the called terminal, sending a data communication request to the called terminal through the speech communication link, receiving a data communication response sent by the called terminal, and transmitting a data communication control command according to the data communication response; and a second communication module which is used for receiving the communication control command, building a data communication link with a network side according to the communication control command, and implementing the data communication with the called terminal by the data communication link. The invention also discloses a corresponding wireless communication method, the called terminal and a wireless communication system. The invention has the advantages that: voice services and data services can be offered simultaneously, the video telephone is realized, and the invention can be applied to the current mature network and will not impose additional burden to the network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless communication terminal, method and system. Background technique [0002] CDMA2000 (multi-carrier division multiplexing spread spectrum modulation) is the name used by the TIA standard organization to refer to the third generation of CDMA. The first phase of CDMA2000 is also known as 1x. At present, the CDMA network is basically based on the CDMA2000 1X Release 0 standard. Its main feature is to continue to use the core network based on ANSI-41D, and add network entities supporting packet services to the radio access network and core network. This version has been stabilized, and the single carrier is the highest. The uplink and downlink rates can reach 153.6kbit / s. The CDMA2000 1X network can be used as a platform for carrying voice services, or as a platform for wirelessly accessing Internet packet data. It can not only provide users with traditional voice services,...
