Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] figure 1 It shows a schematic diagram of a control device for implementing data transmission between terminal devices in a BBU pool system according to one aspect of the present invention; wherein, the control device includes acquiring means 11, determining means 12, forwarding means 13, and sending means 14 . Specifically, the acquiring means 11 acquires the data transmission request sent by the source terminal equipment to the target terminal equipment, wherein the source terminal equipment corresponds to the first BBU in the BBU pool system; the determining means 12 determines that the BBU pool system and The second BBU corresponding to the target terminal equipment; the forwarding means 13 forwards the data transmission request from the first BBU to the second BBU; the sending means 14 transmits the data transmission request via the second BBU se...

The invention aims to provide a method and equipment used for realizing data transmission between terminal equipment in a BBU pool system. A data transmission request is obtained in a BBU pool, and according to a first BBU, corresponding to the source terminal equipment, in the BBU pool system and a determined second BBU, corresponding to the target terminal equipment, in the BBU pool system, the data transmission request is transmitted to the second BBU from the first BBU, and finally, the data transmission request is sent to the target terminal equipment through the second BBU. Compared with the prior art, the method and equipment used for realizing data transmission between the terminal equipment are based on the BBU pool, so that resources between base bands can be shared mutually, and therefore when two or more pieces of terminal equipment corresponding to BBU equipment in the BBU pool conduct data exchange, data exchanged between the source terminal equipment and the target terminal equipment can be completely exchanged in the BBU pool and do not need to be transmitted back to a progressive packet core network to be transmitted. By means of the mode, delay of data transmission between the terminal equipment can be lowered rapidly, and data transmission loads in back-transmission can also be reduced.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a technology for realizing data transmission between terminal devices. Background technique [0002] Generally, in the process of LTE data transmission, the data transmission between two terminal devices needs to go through two eNBs (evolved Node B, evolved base station), backhaul link, serving gateway, PDN (public data network, Public DataNetwork ) gateway and multiple nodes including some additional routes as required, wherein the terminal device is connected to the two eNBs. Since multiple network elements are involved in data transmission and a long link is required, a corresponding long transmission delay is unavoidable. Contents of the invention [0003] The purpose of the present invention is to provide a method and device for realizing data transmission between terminal devices in a BBU pool system. [0004] According to one aspect of the present inventio...
