Embodiment Construction

[0039] The basic idea of ​​the embodiment of the present invention is to combine the broadcast / multicast with the communication method, and use the network coding method to process the transmission data when the network resources permit, and provide a corresponding coding router, which can combine the existing broadcast / multicast with the communication method. The combination of networks makes the allocation and utilization of bandwidth more flexible, thereby greatly improving the efficiency of system data transmission.

[0040] The backbone network of an embodiment of the communication system of the present invention is as figure 2 As shown, the system includes:

[0041] An encoding router, configured to process the first data from the first terminal group sent from the first terminal group to the second terminal group and the second data from the second terminal group sent from the second terminal group to the first terminal group Encoding, generating network coding data; ...

Abstract

The invention discloses a communication system comprising a coding router, a first cell base station, a second cell base station and a broadcast base station, wherein the coding router is used for coding first data and second data so as to generate network coding data; the first cell base station is connected with the coding router and used for supplying a communication service to the first terminal group; the second cell base station is connected with the coding router and used for supplying the communication service to the second terminal group; the broadcast base station is connected with the coding router, covers the first terminal group and the second terminal group, and is used for transmitting the received network coding data to the first terminal group and the second terminal groupin a broadcast mode. The invention also discloses a corresponding method comprising the step: after the data transmitted from a terminal carries out network coding, the data is broadcast to each terminal by the broadcast base station. The invention also discloses the coding router for carrying out the network coding on the terminal data. The invention improves the effective data transmission ratein a backbone network, the network resource utilization ratio, the system volume and user experience.

Description

technical field [0001] The invention relates to a comprehensive technology of broadcast / multicast and communication, in particular to a communication system and method, and an encoding router. Background technique [0002] In an integrated broadcast / multicast communication network, network resources are usually divided into two parts, which are used for transmission of broadcast / multicast services and communication services respectively. Such as figure 1 As shown, in the integrated broadcast / multicast communication network, terminal 1 is within the coverage of cell base station 1, terminal 2 is within the coverage of cell base station 2, and cell base station 1, cell base station 2, and broadcast base station are interconnected through a router. The broadcast base station covers cell base station 1 and cell base station 2 . Among them, the broadcast base station is used to provide broadcast / multicast services to the terminal, and the cell base station provides communicatio...
