Description
Technical field
The present invention relates to the foundation and the data transmission method of radio bearer in the communication system.
Background technology
In the wireless communication system, signaling message will carry necessary information, in order to set the agreement entity of layer 2 (as Radio Link control, medium access control system etc.) and layer 1 (physical layer), and in order to set up the radio bearer passage of data packet delivery, in the hope of by air interface, between terminal and network, carry out the transmission and the reception of packet.
This radio bearer passage, no matter transmitting therein is business datum, or signaling, all the notion with radio bearer defines it.Radio bearer can be complied with its application target, is divided into several classes:
Signaling Radio Bearer: the radio bearer passage that is used for bearer control signalling;
Business datum radio bearer: the radio bearer passage that is used for all kinds of business data packet such as voice-bearer, Streaming Media, mutual or background.
The process of setting up of Signaling Radio Bearer as shown in Figure 1, terminal sends demand signalling to network, Signaling Radio Bearer is set up in request, network side is set up the Signaling Radio Bearer of what sample by the terminal of setting up the signaling message announcement, carries the necessary configuration parameter of setting up Signaling Radio Bearer in this signaling message.After terminal is set up the Signaling Radio Bearer of network appointment, reply network to finish signaling.
The process of setting up of business datum radio bearer as shown in Figure 2, all kinds of business data packet situations such as the voice of network based required carrying, Streaming Media, mutual or background, set up this business datum radio bearer by setting up signaling message notice terminal, in this signaling message, carry the necessary configuration parameter of setting up the business datum radio bearer.After terminal is set up the business datum radio bearer of network appointment, reply network to finish signaling.
There is following defective in the said process:
Setting up needs to carry the necessary configuration parameter of setting up Signaling Radio Bearer or business datum radio bearer in the signaling message, these supplemental characteristic amounts are huge, and signaling has occupied the major part of call delay in the transmission of eating dishes without rice or wine.The time delay of the first bag business data packet also needs the long period thereupon, and that this is the user is highstrung, directly at the experience of this business, be important Service Quality Metrics;
And the setting up in the process of Signaling Radio Bearer, changes little under the layer 2 parameter overwhelming majority situations of configuration signal radio bearer, preceding once with after once Signaling Radio Bearer set up the layer 2 parameter basically identical of configuration signal radio bearer in the process; Equally, for a kind of business, layer 2 parameter of configuration service Data Radio Bearer, also changes little under most situations.But in said method,, all need time radio bearer of time repeated configuration identical (identical) to set up process as layer 2 parameter configuration even set up the radio bearer (carrier signaling or business datum) of same parameter configuration.Thereby cause handling complexity and inefficiency.
At present existing a kind of optimizing process, this method is come unique identification by layer 2 parameter configuration of several business datum radio bearers of prior agreement and with config. number, in the aforementioned no longer carrying layer 2 configuration parameter information of inciting somebody to action in the signaling message of setting up, get final product and only carry the uniquely identified config. number.Save the signaling transmission of eating dishes without rice or wine like this, but had following defective:
It is arranged parameter configuration in advance and defines the radio bearer identifier, the radio bearer identifier pre-configured for the different business Data Radio Bearer is overlapping, for each business datum radio bearer, its pre-configured radio bearer identifier all is to begin to distribute from identical starting symbol, for example all since 5.Set up in the process at radio bearer, for first business, need explicit signaling set up process, it may be noted that configuration or predefined config. number that each radio bearer uses, and in signaling the mapping relations between configuration service Data Radio Bearer and the RAB.Cause voice and packet data concurrent service so, after just first kind of business (as speech) set up, when setting up the 2nd kind of business (as video telephone) again, the 2nd kind of business just can't be used pre-configured, must be pointed out the configuration that radio bearer uses, and in signaling the mapping relations between configuration service Data Radio Bearer and the RAB.
Therefore, this optimizing process is merely able to be applicable to business datum radio bearer configuration for the first time, and follow-up have business datum radio bearer configuration foundation just can't be suitable for again, just can't optimize for there being a plurality of business datum radio bearers configurations to set up process.
