Description
Technical field
This application involves the communication technology, in particular to moving method of a kind of UE between RNC.
Background technique
In existing mobile communication system, switching of the UE between different RNC is called migration.Fig. 1 is before transition process
Schematic diagram afterwards.Currently, RNC starts Fig. 2 after receiving measurement report that UE is reported and judgement needs to carry out to migrate between RNC
Shown in migrate process.In the transition process, if SRNC migrates failure before issuing physics Channel reconfiguration message, or
Person receives physical channel failure, can retract, not influence to communicate；SRNC issue physics Channel reconfiguration message it
Afterwards, no matter migrate successfully or migration fails, it is necessary to discharge SRNC and neutralize the relevant all resources of the UE.
In transition process, if TRNC fails before receiving wireless link recovery instruction (becoming SRNC),
Migration failed message is sent, and discharges all resources distributed in transition process；Wireless link recovery instruction is received in TRNC
After (becoming SRNC), in case of migration failure, then RRC connection is directly discharged.
In any stage of transition process, it is likely to receive the IU release command from CN.If SRNC is in exhalation
IU release command is received before reason Channel reconfiguration message, stops to migrate and retract, IU release command is given at RRC submodule
Reason；If SRNC receives IU release command after issuing physics Channel reconfiguration message, the resource in SRNC is discharged；TRNC
IU release command is received, migration is stopped, discharges resource；After TRNC receives physical channel completion message, become SRNC.
From the foregoing, it can be seen that UE may be caused migration to fail by a variety of situations generation when migrating between different RNC.
In existing mobile communication system, before carrying out business data transmission, need to initially set up RAB.Currently, in business
Establishing before completing does not allow migrate between RNC (i.e. before RAB establishes completion), to avoid unsuccessfully being caused by migrating between RNC
Business establish and access procedure failure.Since business establishes completion, the migration between RNC can be carried out.But it is actually answering
In, just carry out migrating between RNC although being also found that after business is successfully established, still occur success rate of business insertion compared with
Low problem.
Summary of the invention
The application provides a kind of moving method of UE between RNC, can be improved the success rate of service access.
To achieve the above object, the application adopts the following technical scheme that:
A kind of moving method of UE between RNC, comprising:
RNC is after receiving RAB Assignment Response, if only one current RAB, starts preset migration
Forbid timer；
When RNC receives the measurement report of UE and judgement needs to migrate between RNC, if the migration forbids timer to have been turned on
And have not timed out, then the RNC retransmits measurement control message to UE；If the migration is forbidden timer inactive or is had timed out,
Then the RNC initiates migration process.
Preferably, establishing the time for completing to start until NAS signaling terminates according to business, the migration is set and forbids determining
When device timing length, guarantee before the NAS signaling terminates it is described migration forbid timer not overtime.
As seen from the above technical solution, in the application, RNC is after receiving RAB Assignment Response, if currently
Only one RAB then starts preset migration and forbids timer；The measurement report of UE is received in RNC and judgement needs to move between RNC
When shifting, if the migration forbids timer to have been turned on and have not timed out, the RNC retransmits measurement control message to UE；If described
Migration is forbidden timer inactive or is had timed out, then the RNC initiates migration process.By the above-mentioned means, being established in business
Before timer expiry is forbidden in the migration set after the completion, do not allow to carry out to migrate between RNC, to avoid after the completion of business is established
When carrying out service access, due to access failure caused by migration failure between RNC, the success rate of service access is then improved.

Specific embodiment
In order to which the purpose, technological means and advantage of the application is more clearly understood, the application is done below in conjunction with attached drawing
It is further described.
It is successfully accessed the lower problem of rate for current operation, applicant establishes and connects between migration existing RNC and business
Enter process to be analyzed as follows:
In current business foundation and access process, as stated in the background art, although forbidding in business establishment process
Migrate between RNC, but business can carry out migrating between RNC after the completion of establishing.However RAB is established and is completed also to have NAS
Signaling, as Fig. 3 and Fig. 4 CS calling procedure in and PS PSDP activation when RAB establishment process shown in, in RAB
Have NAS signaling after Assignment Response, as Alerting, Connect, Connect Acknowledge,
Activate PDP Context Accept etc..
After the completion of business is established, start to execute access procedure, if initiating migration process in access procedure, and
Migration failure has occurred before the NAS signaling end of transmission, then the migration can unsuccessfully cause access procedure to fail, thus causes
Success rate of business insertion low problem.
From the above analysis as can be seen that having carried out RNC after the completion of establishing just because of business, before the NAS signaling end of transmission
Between migrate, so as to cause the low problem of success rate of business insertion.Based on this, the application using Fig. 5 RNC between moving method,
To improve success rate of business insertion, as shown in figure 5, this method comprises:
Step 501, RNC is after receiving RAB Assignment Response, if only one current RAB, starting are pre-
If migration forbid timer.
Here, in only one RAB, timer is forbidden in starting migration, so as to utmostly simplify the processing of RNC.
Step 502, RNC receives the measurement report of UE, and decides whether migrate between RNC.If judgement is migrated,
Step 503 is executed, this step is otherwise repeated.
After RNC is migrated between the measurement report and judgement for receiving UE need to carry out RNC, subsequent processing is continued to execute, such as
Fruit judgement does not need migrate between RNC, then continues waiting for receiving the measurement report that UE is reported next time, and make decisions.
Step 503, currently whether starting migration forbids timer for judgement, if having been started up and having not timed out, thens follow the steps
504, if inactive or have timed out, then follow the steps 505.
Step 504, RNC does not initiate to migrate between RNC, and retransmits measurement report to UE, under the UE to be received such as return step 502
Secondary measurement report and judgement.
In this step, before timer expiry is forbidden in migration, without being migrated between RNC, to avoid being lost by migrating between RNC
The failure of service access caused by losing.Wherein, migration forbids the timing length of timer to preset, it is preferable that can be according to industry
The time for completing to start until NAS signaling terminates is established in business, the timing length for migrating and forbidding timer is arranged, to protect
Card migration before NAS signaling terminates forbids timer not overtime.
Step 505, switching flow between initiation RNC.
Specific switching flow is same as the prior art, just repeats no more here.
So far, method flow shown in fig. 5 terminates.By the above method, in setting time after the completion of business is established,
Forbid migrating between RNC, to avoid that migration failure occurs before NAS signaling terminates and service access is caused to fail, then improve
The success rate of service access.
Above-mentioned method application shown in fig. 5 is tested in the rnc, obtains test result shown in fig. 6.Specifically,
In Fig. 6, start " timer is forbidden in migration " after RAB Assignment Response at (1)；NAS signaling is in (2)
The measurement report of UE is received before not terminating, RNC is adjudicated according to measurement report needs to initiate migration, but " migration is prohibited due to having been turned on
Only timer ", so not initiating to migrate；Measurement control is retransmitted at (3) to UE；The measurement report RNC of UE is received at (4)
According to measurement report adjudicate need initiate migration, " timer is forbidden in migration " has timed out at this time, thus initiated migration, migration at
Function.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
