Multi-service link distribution and reorganization device and method

Abstract

The invention provides a multi-service link distribution and reorganization device and method. The device comprises a service multi-link distribution module and a service multi-link reorganization module, wherein the service multi-link distribution module can classify services of different input service streams according to service quality requirements, detect available links, and then distribute the classified service streams to different links, and the classified service streams are sent out through a service multi-link transmission module; the service multi-link reorganization module is used for compensating for the time delay of the different links of the services which are received by a service multi-link receiving module so as to balance link loss, reorganize the service streams and restore original service streams. According to the scheme of the multi-service link distribution and reorganization device and method, link resources are distributed to the different services at the sending end according to link states and the service quality requirements, as a result, service transmission demands are met, and the utilization rate of system channel resources also can be increased; time delay and loss compensation can be conducted on data at the receiving end, and meanwhile, the out-of-order problem in parallel transmission is solved due to the fact that the same service is reorganized according to the type and package number of the service.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a device for distributing and recombining multi-service links and a method thereof. Background technique [0002] Today, the third-generation mobile communication technology (3G) is becoming more and more popular, and the new-generation wireless mobile communication system (4G) is becoming more and more mature. Other technologies such as wireless local area network and wired optical fiber network have also been widely used. On the basis of the full development of these technologies, relying on existing resources to develop special-purpose communication support capabilities is a very important development direction in the future. Typical examples of this special purpose include Wenchuan earthquake emergency command and Olympic security. How to ensure communication security, reliability, stability and flexibility in these scenarios is a problem that must be co...

Problems solved by technology

Although this patent assigns services to different links for transmission according to the proposed algorithm, the allocation algorithm only considers the state information of the channel, and does not take the service quality requirements of the service as a consideration factor. When the required business is transmitted in parallel, this method cannot achieve optimal performance

[0008] The present invention mainly solves the problem of how to efficiently and reliably transmit services with different quality of service requirements on multi-link transmission channel resources. To solve this problem, the following problems need to be overcome: 1) How to: Service allocation channel resources; 2) When using heterogeneous resources for transmission, the same service may be transmitted in parallel through multiple links, and data packets may be out of order

And above-mentioned patent fails to solve these difficult problems uniformly
