101, set up and eat dishes without rice or wine to be connected with terminal;
After terminal makes a call connection, BSC and terminal are carried out the configuring negotiation of session attribute, BSC sends Traffic Channel Assignment (TCA according to the state of each channel to terminal, Traffic ChannelAssignment) message, terminal is according to after this TCA message selected data transmission channel, send Traffic Channel to BSC and complete (TCC, Traffic Channel Complete) message, confirm to set up and eat dishes without rice or wine to be connected with BSC.
This terminal can be computer or the notebook computer of radio telephone, wireless networking, can be also mobile station equipment.
102, obtain and set up the carrier number connected of eating dishes without rice or wine;
After terminal receives TCA message, know to set up which carrier wave from this TCA message, launch reverse signal on the carrier wave that terminal is set up at needs, BTS catches this reverse signal on the carrier wave of each foundation, if acquisition success, this carrier wave is successfully established, and BSC obtains the message that the BTS carrier wave is successfully established, and adds up the number that all these terminals and BTS successfully set up carrier wave.
If the carrier number got is 1, the system type that this terminal is used is single-carrier system (as: EVDO REVA), due to the resource-constrained of single-carrier system binding, therefore the user of single-carrier system can not cause excessive seizing to Internet resources when using the P2P business;
If the carrier number got is more than two, the system type that this terminal is used is multicarrier system (as: EVDO REV B), at EVDO REV B in such multicarrier system, bandwidth between whole BSC and terminal is divided into 3 carrier waves, the user of EVDO REV B can bind together the Radio Resource of 3 carrier waves (comprising: channel and time slot), can improve the peak velocity of 3 times; If the user of EVDO REV B uses the P2P business, be equivalent to 3 EVDO REV party A-subscribers and use the P2P business simultaneously, make the suddenly aggravation of seizing of Internet resources, badly influence other users' business experience.

In the prior art, PDSN-AAA notifies the transmission priority A of terminal to after BSC, the scheduler of BSC will determine when be these terminal transmission data according to this transmission priority A, because the PDSN-AAA in prior art can't be known the carrier number of terminal when foundation eats dishes without rice or wine to connect, can only distribute transmission priority according to general precedence, make the terminal of overloading wave number have precedence over follow-up single carrier terminal and carry out transfer of data, once run into the busy period of network, can affect follow-up most single carrier terminal and carry out transfer of data.And in an embodiment of the present invention, BSC is after getting transmission priority A, the carrier number according to this terminal when foundation eats dishes without rice or wine to connect is adjusted transmission priority A, makes the transmission priority A after adjustment
NMore reasonable.
At adjustment unit, 403 couples of transmission priority A are adjusted computing, obtain transmission priority A
NAfterwards, BSC is according to described transmission priority A
NCarry out transfer of data with described terminal; The first transmitting element 404 sends a notification message to terminal, carries the transmission priority A after renewal in this notification message
N, make this terminal use transmission priority A
NUpgrade local transmission priority, thereby, when terminal sends data to PDSN, the scheduler of terminal can mate the order of transmission corresponding with BSC and carry out transfer of data.
When terminal is initiatively initiated the channel renewal, the channel update request that the second receiving element 407 receiving terminals send, and trigger the second transmitting element 405, enter the flow process that Traffic Channel is upgraded.
After the second receiving element 407 receives the channel update request of terminal transmission, BSC analyzes this channel update request, determine channel and the carrier resource of distributing to this terminal, send Traffic Channel Assignment message by the second transmitting element 405 to this terminal, carry channel and the carrier resource of distributing to this terminal in this Traffic Channel Assignment message.This Traffic Channel Assignment message can be TCA message, and this channel comprised in this Traffic Channel Assignment message and carrier resource information can be channel and the carrier resources of fixedly assignment, can be also optional channel and carrier resource.
The Traffic Channel updating message that first receiving element 406 these terminals are returned, confirm that terminal again sets up and eat dishes without rice or wine to be connected with BSC, and trigger the first acquiring unit 401 and obtain the eat dishes without rice or wine carrier number of connection of this terminal foundation in this Traffic Channel updating message.This Traffic Channel updating message can be TCC message.Detecting unit 408 detects with this terminal and sets up the carrier number N that eats dishes without rice or wine to be connected, if this carrier number changes, triggers adjustment unit 403 and again this transmission priority A is adjusted.
In actual applications, except terminal can initiatively be initiated the renewal of Traffic Channel, AN equipment (as BTS) also can be initiated the more new technological process of Traffic Channel, after BTS initiates the Traffic Channel renewal, trigger the second transmitting element 405 and carry out corresponding operation, the specific works flow process is similar to the flow process that above-mentioned terminal originating service channel upgrades, and does not repeat them here.
