The present invention can effectively shorten the connecting time delay of the service requests.
Description
Technical field
The present invention relates to the service call treatment technology of communication system, relate in particular to a kind of communication system processing method to service bearer when initiating service request.
Background technology
The time delay that continues is an especially third generation wireless telecommunication system of wireless telecommunication system, Wideband Code Division Multiple Access (WCDMA) (WCDMA) system for example, in a major issue, the long meeting of the time delay that continues directly influences user's subjective feeling, influences the loyalty of user to the communication Operation Network.
In the existing technical scheme about WCDMA of third generation collaborative project (3GPP), professional foundation generally is divided into two stages, the one, RRC establishment of connection, the 2nd, the foundation of radio bearer RB.Flexibility in order to keep setting up business, Access Network is issuing all relevant parameter all to be gone down from the transmission of eating dishes without rice or wine when RB sets up at every turn, the message that causes RB to set up like this is very big, add under the situation that the transmission error code of eating dishes without rice or wine certain retransmits, make that the time delay of signaling transmission is very big, thereby had a strong impact on the time delay of professional foundation, QoS (QOS) and user QOE have all been had bigger influence.
At this defective, 3GPP is proposing a kind of new prioritization scheme to circuit domain (CS) and packet domain (PS) call delay.
Described prioritization scheme mainly be pre-configured (Preconfiguration) thought, now comprise: predetermined configuration (Pre-defined configuration), default configuration (Default configuration) and stored configuration (Stored configuration) scheme.The juche idea of these three kinds of schemes is identical, and this scheme of sentencing stored configuration is that example is introduced.
The stored configuration scheme is exactly that the parameter configuration of the business that will set up is stored in terminal (UE) and Access Network (UTRAN) two ends in advance, just directly uses these parameters when business is formally set up, and has transmitted and not be used between UTRAN and the UE.Owing to need different configuration parameters for different RB, therefore the set (being called a RB configuration item) for different RB configuration parameters just need identify, UTRAN directly issues certain RB sign when business is set up, UE sets up RB according to the corresponding RB configuration parameter of this RB sign of the local storage of this RB sign inquiry according to the RB configuration parameter that inquires.
Use stored configuration set identification (SCSI, Stored Configuration SetIdentity) and storage configuration identification (SCI, Stored Configuration Identity) to identify a RB configuration item jointly in the prior art.Fig. 1 is the schematic diagram that utilizes SCSI and SCI sign RB configuration item.Referring to Fig. 1, SCI is an element in the SCSI set, system can produce different SCSI according to different property class, be that relevant high speed downlink packet inserts the configuration set of (HSDPA) such as certain SCSI, and another SCSI is the relevant configuration set that strengthens dedicated channel (EDCH) etc.Management unit for the RB sign is target with SCSI, and SCSI is made up of with a release label relevant with the time a config set numbering.A concrete SCI is made up of SCSI and its corresponding configuration identifier (Configuration Identity).
In the disclosed technical scheme of existing 3GPP 25.331R6 release protocol, at Radio Resource control (RRC, Radio Resource Control) comprises pre-configured state information (Predefinedconfiuration status information) cell in the message, this cell is with pre-configured relevant, if be set to true value (TRUE), it is pre-configured that network side knows that by this IE UE can carry out; If be set to empty value (FALSE), network side knows then that UE is current does not have a preconfigured information.
Fig. 2 sets up the flow chart of SCI and RB information stores corresponding relation between UE and the UTRAN for prior art.Referring to Fig. 2, this flow process mainly comprises:
Step 21, UTRAN are set to very (TRUE) with the transmission preconfigured information field (SendStoredConfigurationInfo) in the RRC Connection Setup message, and notice UE reports the SCI tabulation of being stored.
Step 22, UE send RRC connection setup complete message (RRC Connection setupcomplete) to UTRAN, comprising SCI tabulation, i.e. pre-configured list (Stored Configurationlist included).
Step 23, UTRAN learn the SCI tabulation that UE stores; As RB that UTRAN will set up in the tabulation that UE reports and in the time of non-existent, then UTRAN sets up SCI and the pairing bearing parameter (bearparameters) that notice UE will set up in (RadioBearer Setup) message at radio bearer.
Step 24, UE store the corresponding relation of SCI and bearing parameter, finish the process of setting up of RB; Set up at radio bearer and to finish that informing network has upgraded the SCI tabulation in (Radio Bearer Setup Complete) message, comprising pre-configured list.
Fig. 3 sets up the flow chart of RB for SCI and RB information stores corresponding relation between prior art use UE and the UTRAN.Referring to Fig. 3, this flow process comprises:
Transmission preconfigured information field in step 31, the UTRAN RRC Connection Setup message is set to very (TRUE), and notice UE reports the SCI tabulation of being stored.
Step 32, UE send the RRC connection setup complete message to UTRAN, and comprising the SCI tabulation, UTRAN learns the SCI tabulation that UE stores.
Step 33, when RB that UTRAN will set up exists in the SCI tabulation that UE reports, UTRAN sets up the RB that only adopts SCI to indicate UE to set up in (Radio Bearer Setup) message at radio bearer.
After step 34, UE receive SCI, find the RB configuration item of this SCI correspondence, and set up this RB according to the event memory of UE.Because the pre-configured list of UE is not upgraded, set up at radio bearer and to finish in (Radio Bearer Setup Complete) message the informing network side and do not upgrade the SCI tabulation, promptly do not comprise the SCI tabulation.
But, there is not the cell that is used to identify the RB that builds in existing RRC connection request message, can't notify the UTRAN current business to wish the RB type of handling immediately by UE, UTRAN needs to wait for, after UE and CN consult, and arrives UTRAN by RAB (RAB) assignment message that CN issues, UTRAN could finish the mapping of RAB to RB according to the assignment of this message, learn the RB information that UE will set up or reshuffle, the resource of beginning RB is prepared, and issues corresponding message and give
UE sets up or reconfiguration course to finish RB; Therefore the resource of prior art RB is prepared and sets up to be subject to the RAB assignment when UTRAN receives CN, causes the time delay that continues of existing business request call longer.

Fig. 7 be first embodiment of the invention described when service request to the process chart of RB.Referring to Fig. 7, this flow process comprises:
Step 71～step 72, UE are when the service call flow process of new initiation, when for example initiating the foundation of applied business or revising request, according to the mapping relations of the type of service of being initiated and type of service and PCI, find the PCI of present type of service mapping, and this PCI is sent to UTRAN.
Step 73～step 74, UTRAN are according to the corresponding relation of PCI and RB configuration item, find the RB configuration item of described PCI correspondence, service request according to UE is operated this RB, be specially triggering RB and set up process, or trigger the process that is used to reshuffle RB: for example operations such as reconfiguration course of the reconfiguration course of RB reconfiguration course or Traffic Channel or physical channel; At the operation that is triggered, UTRAN begins the resource of RB and prepares and operating process, issue corresponding operation requests to UE: for example RB sets up request or the reconfiguration request of RB reconfiguration request or Traffic Channel or the reconfiguration request of physical channel etc., and the sign of carrying current handled RB in the request message is PCI.
Step 75～step 76, UE receive the RB configuration item of searching described PCI correspondence after the request, according to the request that UTRAN issues this RB are operated, and for example set up this RB, perhaps revise this RB; Return response message and give UTRAN, for example return RB and set up and finish message or RB and reshuffle and finish reshuffling of message or Traffic Channel and finish reshuffling of message or physical channel and finish message etc.
At this moment, the related RB of current business did not just set up or had revised before UTRAN receives the core net Assignment Command, therefore can shorten the time delay that service request continues greatly.
Step 77, UTRAN receive the RAB Assignment Command from core net.
Step 78, assignment is mapped to RB according to RAB, and compares with RB that step 73 was handled, if RB is identical, and execution in step 79; Otherwise, the RB mistake that determination step 73 is handled, execution in step 710.
Step 79, UTRAN respond successful RAB assignment response, process ends to core net.
The resource of step 710～step 711, modification UTRAN, carry out RB according to the RB of RAB assignment mapping and reshuffle, and the sign that the message (specifically can be the reconfiguration request of RB reconfiguration request or Traffic Channel or the message such as reconfiguration request of physical channel) that RB reshuffles in being used for of issuing to UE is carried RAB RB that assignment is shone upon is PCI.
Step 712～step 713, UE receive the RB configuration item of searching described PCI correspondence after the request, and the request that issues according to UTRAN is operated this RB and promptly reshuffled this RB; Return response message and give UTRAN, for example return RB and set up and finish message or RB and reshuffle and finish reshuffling of message or Traffic Channel and finish reshuffling of message or physical channel and finish message etc., return the RAB assignment after UTRAN receives and respond to CN; UE also is updated to the PCI that UTRAN issues with the PCI of present type of service mapping, so as next time during service request UE can correctly handle RB.
Above-mentioned flow process is a related process in the service request of the present invention, re-executes above-mentioned flow process when new service request.
In the second embodiment of the present invention, similar to the flow process of first embodiment, but the RB that reports as the RB and the UE of RAB assignment mapping is not simultaneously, can also further carry out following special processing: in service request, if the RB of RAB assignment mapping is different with the RB that UE reports, then once to this terminal accumulative total; When the cumulative number of terminal surpasses default value, then Access Network is when N service request of this terminal of processing subsequent, after step 73, do not handle RB by step 74～step 76, but handle RB according to the RB that the RAB assignment that core net issues is shone upon, promptly after step 77 was received RAB assignment request, execution in step 710 was to step 713; Described N is the positive integer greater than zero.The processing intent of this embodiment is that UTRAN punishes the mistake that reports of UE.After greater than N time, UTRAN just responds the PCI that UE reports, and uses this PCI to set up or revise RB as UE.
In the third embodiment of the present invention, similar to the flow process of first embodiment, if but the RNC among the UTRAN has also stored the mapping relations between type of service and the PCI, then after UTRAN receives the PCI that UE reports, from the described mapping relations of self storing, search the PCI of present type of service mapping, according to Query Result the PCI that UE reports is examined,, then continue to carry out subsequent step of the present invention if the same; If different, then the PCI that self is stored and finds is handed down to UE, and UE is updated to the PCI that UTRAN issues with the PCI of present type of service mapping.
Further, the 3rd embodiment is in service request, if the PCI that UTRAN finds is different with the PCI that UE reports, then further to this terminal accumulative total once; When the cumulative number of terminal surpasses default value, then Access Network is when N service request of this terminal of processing subsequent, after step 73, do not handle RB by step 74～step 76, but handle RB according to the RB that the RAB assignment that core net issues is shone upon, promptly after step 77 was received RAB assignment request, execution in step 710 was to step 713; Described N is the positive integer greater than zero.After greater than N time, UTRAN just responds the PCI that UE reports, and uses this PCI to set up or revise RB as UE.
In addition, in step 72, UE sends to PCI and can introduce new cell in the used message of UTRAN and carry PCI, for example, referring to table 1, comprise two newer fields, wherein type field is used to represent that this PCI is predetermined configuration (Pre-defined configuration) sign, default configuration (Defaultconfiguration) sign, still stored configuration (Stored configuration) identifies; The PCI value that the PCI field record is concrete.
| Type | Predetermined configuration sign, default configuration sign or storage configuration identification | The type of PCI is described |
| PCI | Integer type | The RB sign that the UE request is set up or revised, UTRAN finds the RB configuration item that will set up or revise according to this PCI |
Table 1
In addition, newly-increased cell can be the PCI field only also, referring to table 2,
| PCI | Integer type | The RB sign that the UE request is set up or revised, UTRAN can find the RB configuration item that will set up or revise according to PCI |
Table 2
In addition, also can carry out expanded definition at the inner types value of introducing of PCI field, identifying this PCI with three kinds of different values is predetermined configuration sign, default configuration sign, or storage configuration identification.
