Embodiment
The present invention is by setting in advance typical performance relevant parameter, and the mobile network is displaced sideways user side and sends and connect when setting up message, directly adopts mutual concession one cover canonical parameter, and the index value of the canonical parameter of approval is encapsulated in to connect sets up in the message.
Referring to shown in Figure 2, realize that method of the present invention may further comprise the steps:
Step 201, set in advance the recommended configuration parameter vector set that comprises the parameter relevant, for parameter vector element in the described recommended configuration parameter vector set is provided with index value one to one with the Connection Service quality; This recommended configuration parameter vector set comprises more than one parameter vector element, each parameter vector element is corresponding to the configuration parameter under the specific wireless environment of being connected of one group of certain quality of service or particular traffic type, and, in order to use conveniently, two identical recommended configuration parameter vector set can be set, a recommended configuration parameter vector set is arranged on mobile network's side, another recommended configuration parameter vector set is arranged on mobile subscriber's side;

The message that step 203, mobile network's side will contain index value at least is sent to mobile subscriber's side, and mobile subscriber's lateral root obtains corresponding configuration parameters according to the set of the recommended configuration parameter vector described in this index value index step 201.
Describe technical scheme of the present invention in detail below in conjunction with the drawings and specific embodiments.
For technical scheme more clearly is described, present embodiment will connect the parameter of setting up in the message and be divided into two classes.
The first kind is for there being the parameter of sign effect in this connection, this class parameter of different mobile subscriber's sides is different.Generally, the number of first kind parameter is less, and mobile subscriber's side must accurately be known these parameter values in a connection, otherwise may obscure with other mobile subscriber's sides.Be designated example with the initial movable user side on the access channel, this connection identifier can be called the temporary mark of this mobile subscriber's side, deletes when connection closed.Mobile subscriber's side need by this initial movable user side sign differentiate this connection message be oneself or other mobile subscriber's side.For another example, the DPCH basic parameter, as frequency, time slot or channel code etc., mobile subscriber's side can be used the DPCH of specific distribution in view of the above, and then uses the specific user profile of DPCH transmission.
Second class is the service quality relevant parameter of this connection.As, mapping relations etc. between transmission block size, transmission block number, sliding window size, retransmission timer, counter, priority of logical channels and logic channel and the physical channel.This class number of parameters is more, and for different mobile subscriber's sides, this class parameter value can be identical, also can be different.In a connection, these parameters and actual needs have certain deviation, but this deviation often just has influence on the service quality of this connection, and can not have influence on establishment of connection.
As can be seen, first kind parameter is less from the above-mentioned parameter classification declaration, and the second class parameter is more.And the second class parameter is the performance relevant parameter, and its error can directly not have influence on establishment of connection.Therefore, the present invention is by setting in advance the typical performance relevant parameter of some covers, mobile network's side needn't dispose various performance parameters when setting up message one by one send connecting to mobile subscriber's side on the forward access channel, but only points out it is which cover parameter of mutual concession gets final product.
Introduce the process of the recommended configuration parameter vector set of the pre-defined second class parameter below in detail.
At first, remember that the second class parameter is a parameter vector
Wherein n represents the second class number of parameters, p
i, i=1,2 ..., n represents i parameter of the second class parameter.If each parameter p
iK is arranged
iPlant value, then the total vector of the second class parameter may the value number
Then, support the characteristics such as type of service, service quality and Radio Resource environment that connect, define the recommended configuration parameter vector set of this mobile communication system according to this mobile communication system
M is the number of vector in this set, each element vector in this set
It is the second class parameter vector
One group of value.Here vectorial
Corresponding one group of particular traffic type, certain quality of service be connected configuration parameter under the specific wireless environment.Owing to only comprised typical parameter set in the S set, removed a large amount of configuration parameter vectors that is of little use, this set sizes m is far smaller than the total possible value number K of the parameter second class parameter usually.
Shown in Figure 3 referring to flow process, after the set that has defined the second class parameter, the process that connects between mobile subscriber's side and the mobile network's side is as follows:
Step 301, mobile subscriber's side send a connection by Reverse Access Channel to mobile network's side and set up request message.And the initialization that carries mobile subscriber's side in this message identifies, and is used for this mobile subscriber's side of sign on Reverse Access Channel.
After step 302, mobile network's side receive that request is set up in the connection of mobile subscriber's side transmission, at first be that this mobile subscriber's side that need connect is distributed a temporary mark; And then distribute the dedicated channel resource of corresponding connection for this mobile subscriber's side, as sign dedicated channels such as frequency, time slot, code channels.By this step, mobile network's side is determined the first kind parameter value of this connection of this mobile subscriber's side.
Step 305, mobile network's side issue packaged connection by forward access channel to mobile subscriber's side and set up message.
After step 309, dedicated channel were set up, mobile subscriber's side by connection setup complete message response mobile network side, connected and sets up on dedicated channel.
Certainly, after connecting foundation, mobile network's side and mobile subscriber's side can be consulted new parameter once more on dedicated channel.
From above-mentioned example as can be seen, receive the connection request of mobile subscriber's side when the mobile network user unit after, mobile network's side is mobile subscriber's side configuration first kind parameter, and chooses one group of second appropriate class parameter vector from predefined recommended configuration parameter vector S set; The index value " j " that to choose vector then in recommended parameter vector S set is encapsulated in to be connected with first kind parameter to be set up in the message, sets up message by connection again the index value of determining is transferred to mobile subscriber's side.This method can reduce to connect the length of setting up message greatly.
This method is by providing the recommendation of the second class parameter in advance, make when mobile network's side is set up parameter for the configuration of mobile subscriber's side connects, only need transmit its index value in this recommended parameter vector set, the information transmitted amount is reduced greatly, and then obviously reduced to connect the length of setting up message, solved the resource bottleneck problem of forward access channel effectively.
