Embodiment Construction
[0025] In order to solve the problems of large bandwidth occupation and low system performance in the process of returning data when satellite communication is used in the prior art. In the embodiment of the present invention, when the gateway agent receives the voice data sent by the first Femto base station, according to the locally carried identification information mapping table, when it is determined that both the first Femto base station and the second Femto base station are connected to the above-mentioned gateway agent, the gateway agent Transmit voice data to the second Femto base station. By adopting the technical solution of the present invention, a gateway agent is added in the wireless communication system. When both the first Femto base station and the second Femto base station are connected to the gateway agent, the gateway agent is used to transmit the voice data sent by the first Femto base station to the second Femto base station. The base station can realize...

The invention discloses a data transmission method and device. The method includes the steps that after a proxy gateway determines that voice links are established between a calling mobile terminal and an MSC and between a called mobile terminal and the MSC respectively, voice link identifying information of voice data sent by a first Femto base station on the gateway proxy side is searched for in an identifying information mapping table, and when it is judged that the first Femto base station and a second Femto base station are both connected into a gateway proxy, the voice data sent by the first Femto base station are transmitted to the second Femto base station. According to the technical scheme, the gateway proxy is additionally arranged in a wireless communication system, when the first Femto base station and the second Femto base station are both connected into the same gateway proxy, the voice data are transmitted between the first Femto base station and the second Femto base station through the gateway proxy, the data postback process can be achieved without satellite equipment, hence, the satellite communication bandwidth is saved, and the system performance is effectively improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] With the rapid development of mobile communication technology, the network structure of the wireless communication system has also changed from the complex open network structure of GSM (Global System Of Mobile Communication) to the IP (Internet Protoal, interconnection protocol) between the entire network. The flat network architecture is gradually evolving. [0003] refer to figure 1 As shown, it is a schematic diagram of the wireless communication system architecture in the embodiment of the present invention. In the wireless communication system, mobile device A and base station A accessed by mobile device A, mobile device B and base station B accessed by mobile device B, and a gateway , and MSC (Mobile Service Switch Center; Mobile Switching Center). When mobile device A is the calling mob...
