Abstract
The method comprises: subscriber equipment sends cell updating message comprising service ID information to radio network controller (RNC); according to service ID information, RNC determines the parameters of configuring subscriber equipment dedicated channel; RNC sends the configuration parameters to the subscriber equipment by using cell updating message; according to the configuration parameters, subscriber equipment turns to CELL_DCH status from CELL_PCH status. The invention informs RNC to initiate the NSAPI or RAB identity of data transmission service in order to make UE directly turn to CELL_DCH status from CELL_PCH status in cell updating process.
Description
Technical field
The present invention relates to the Wideband Code Division Multiple Access (WCDMA) access technology, relate in particular to a kind of state transitions method of wideband CDMA access equipment.
Background technology
WCDMA (Wideband Code Division Multitple Access, the Wideband Code Division Multiple Access (WCDMA) access) in the system, be in UE (the User Equipment of connection mode, subscriber equipment) there are three kinds of state: CELL_PCH (Paging Channel, paging channel) state, CELL_FACH (Forward AccessChannel, forward access channel) state, CELL_DCH (Dedicated Channel, dedicated channel) state.Wherein, the UE that is in the CELL_PCH state adopts DRX (Discontinuous Reception, discontinuous reception) mode monitoring seek channel, in the information of specific calling time monitoring PCH channel, can not carry out transfer of data; The UE that is in the CELL_FACH state monitors the FACH common signal channel continuously and belongs to the data of this subscriber equipment with reception, and transmitting uplink data is used RACH (Radio AccessChannel, wireless access channel); The UE up-downgoing that is in the CELL_DCH state is assigned DPCH, uses the resource of monopolizing to carry out transfer of data.
For saving local resource, for the UE of mutual background business, system can be in data volume hour with UE from CELL_DCH state transition to the CELL_FACH state; If be not activated through data service after a while, UE will be moved to the CELL_PCH state.When UE will go up the line number biography or receive UTRAN (UMTS Territorial Radio Access Network, UMTS Terrestrial radio access network) beep-page message, initiate cell updating course, move to CELL_FACH state or CELL_DCH state again.
Before the R6 version, do not allow UE to directly migrate to the CELL_DCH state from the CELL_PCH state, and must move to the CELL_FACH state earlier, (the value overflow that is RLC BufferOccupancy is measured the 4a threshold value Deng reporting the 4a incident, network should distribute bigger bandwidth to give the user) the measuring business volume report after, network is moved to UE the CELL_DCH state again.In order to shorten the time delay of UE from CELL_PCH state transition to the CELL_DCH state, in cell update message Cell Update, increase IE traffic carrying capacity indication information Traffic volume indicator in the R6 version, when UE initiates cell update, if the trigger condition of the 4a incident of certain measuring business volume is satisfied, then this IE is made as TRUE, otherwise is made as FALSE.If this value is TRUE, network is configure dedicated channel resource in cell update acknowledge message CellUpdate Confirm just, directly UE is moved to the CELL_DCH state.
For downloading this class as file to the business that delay requirement is not high, the data throughout real-time change is bigger that continues, existing scheme can satisfy its demand, and network can report by measuring business volume, and the bandwidth that takies according to the variation adjustment business of business throughput is to save resource.But, also can carry as mutual background business as PoC (Push-to-talk over Cellular, push-to-talk over cellular), VoIP speech businesses such as (Voice over IP, IP-based voice) along with the development of business.But these business are very high to the requirement of time delay, and data throughout changes not quite, does not generally need the dynamic rate adjustment.If adopt existing scheme, the dedicated channel parameters that possible network disposes in Cell Update Confirm message can not accurately satisfy the service bandwidth demand, cause UE to move to the CELL_DCH state and also need to carry out afterwards RB (Radio Bearer, radio bearer) reconfiguration course, the professional time delay that continues increases, and influences user's result of use.
Summary of the invention
The problem to be solved in the present invention provides a kind of state transitions method of wideband CDMA access equipment, originally can't require business high, that data throughout changes little mutual background classes to processing delay to solve prior art, the dedicated channel resource that needs of distribution service exactly, and then reduce the continue defective of time delay of user.
In order to realize above purpose, the invention provides a kind of state transitions method of wideband CDMA access equipment, may further comprise the steps:
A, subscriber equipment send cell update message to radio network controller, comprise professional identification information in the described message;
B, described radio network controller are determined described subscriber equipment dedicated channel configuration parameter according to described service identification message;
C, described radio network controller send to subscriber equipment by the cell update acknowledge message with described dedicated channel configuration parameter;
D, described subscriber equipment are the CELL_DCH state from the CELL_PCH state transitions, and obtain the maximum transmission bandwidth of this service needed according to described dedicated channel configuration parameter.
In the steps A, subscriber equipment is a calling terminal when carrying out transmitting uplink data or receiving network side paging for terminal called, sends cell update message to radio network controller.
The detailed process that subscriber equipment obtains service identification information by network side paging comprises:
Serving GPRS Support Node sends beep-page message to radio network controller, comprises the RAB ID of called service in the described message;
Described radio network controller is converted to the RAB ID of described called service the identification information of called service;
Described radio network controller is issued subscriber equipment by paging Class1 message with the identification information of described called service.
Step B further comprises:
B1, radio network controller are determined the RAB context that this is professional according to described service identification;
Obtain the maximum data bit rate in B2, the QoS parameter from the RAB context;
B3, determine described dedicated channel configuration parameter according to described maximum data bit rate.
Described service identification comprises: Network Service Access Point Identifier NSAPI or wireless access bearing sign RAB identity.
Described dedicated channel configuration parameter comprises: radio bearer parameter and/or transport channel parameters and/or physical channel configuration parameter.
Compared with prior art, the present invention has the following advantages:
The present invention is by RNC (Radio Network Controller, radio network controller) NSAPI (the Network Service Access Point Identifier of the business of initiation transfer of data, Network Service Access Point Identifier) or RAB (Radio Access Bearer, RAB) identity, in cell updating course, make UE directly move to the CELL_DCH attitude from the CELL_PCH attitude, and by this professional maximum data bit rate configuration suitable R B, transmission channel, physical channel parameters, avoid the RB reconfiguration course, shorten the state transition time delay when continuing, improve user's service efficiency.
