Embodiment Construction

[0059] As described in the background, in order to establish a dedicated dedicated data radio bearer, an embodiment of the present invention proposes a method for forwarding data transmission through a dedicated data radio bearer.

[0060] Such as Figure 4 As shown, it is a schematic flowchart of a method for forwarding data transmission through a dedicated data radio bearer provided by an embodiment of the present invention. The method specifically includes the following steps:

[0061] Step S401. When the base station receives a dedicated data radio bearer establishment indication message sent by the network side device, the base station establishes one or more dedicated data radio bearers dedicated to transmitting forwarded data between the base station and the relay node.

[0062] Wherein, the network side device specifically refers to a core network device, and in a specific application scenario, it is an RN MME.

[0063] The specific types of specific network-side devi...

Abstract

The embodiment of the invention discloses a method and equipment for transmitting forwarding data by utilizing a dedicated data radio bearer. According to the application of the technical scheme disclosed by the embodiment of the invention, a forwarding channel is mapped into the dedicated data radio bearer for dedicatedly transmitting the forwarding data on an interface between a base station and rely nodes so that the forwarding data transmission is ensured, a longer time delay of forwarding data transmission, caused by the transmission of the forwarding data and normal user data on the same transmission channel, incapability of meeting requirement if switching interruption time delay and the user experience reduction are avoided, and the influences of the forwarding data on the normal data processing, such as hearder compression and the like are also avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for forwarding data transmission through a dedicated data radio bearer (DataRadio Bearer, DRB). Background technique [0002] In future mobile communication systems, such as B3G: Beyond Third Generation or LTE-A (Long Term Evolution-Advanced, Advanced Long Term Evolution), the system will provide higher peak data rates and cell throughput, while Larger bandwidth is also needed. At present, there are very few unallocated bandwidths below 2GHz, and part or all of the bandwidth required by the B3G system can only be found in higher frequency bands, such as above 3GHz. The higher the frequency band, the faster the attenuation of radio wave propagation and the shorter the transmission distance. Therefore, in the same coverage area, to ensure continuous coverage, more base stations are required. Since base stations usually have a higher cost, this wil...
