Description

A kind of UE moving method between RNC

Technical field

The application relates to communication technology, particularly to a kind of UE moving method between RNC.

Background technology

In existing mobile communication system, UE switching between different RNC is called migration.Fig. 1 was for migrating Schematic diagram behind Cheng Qian.At present, RNC is receiving measurement report that UE reports and judgement needs to carry out between RNC After migration, start the migration flow process shown in Fig. 2.In this transition process, if SRNC is sending physical channel weight Migrate unsuccessfully before configuration message, or receive physical channel reconfiguration failure, can not affect communication with rollback；? After SRNC sends physics Channel reconfiguration message, no matter migrate successfully or migrate failure, it is necessary to release SRNC Neutralize the relevant all resources of this UE.

In transition process, if TRNC lost before receiving wireless link recovery instruction (becoming SRNC) Lose, then send and migrate failed message, and be released in transition process all resources of distribution；Receive wireless at TRNC After link-recovery instruction (becoming SRNC), if it occur that migrate unsuccessfully, the most directly release RRC connects.

In any stage of transition process, it is likely to receive the IU release command from CN.If SRNC is sending out Receive IU release command before going out physical channel reconfiguration message, stop to migrate and rollback, IU release command is given RRC submodule processes；If SRNC receives IU release command after sending physics Channel reconfiguration message, then Resource in release SRNC；TRNC receives IU release command, stops to migrate, discharges resource；TRNC receives thing After reason channel reconfigures completion message, become SRNC.From above-mentioned, UE can when migrating between different RNC Can cause migrating failed generation by multiple situation.

In existing mobile communication system, before carrying out business data transmission, need to initially set up RAB.At present, exist Do not allow (before i.e. RAB has set up) before business has been set up to carry out migrating between RNC, thus avoid by RNC Between migrate the business that unsuccessfully causes and set up and access procedure failure.From the beginning of business has been set up, RNC can be carried out Between migration.But, in actual applications, although being also found that after business is successfully established and just carrying out migrating between RNC, But the problem that success rate of business insertion is relatively low still occurs.

Summary of the invention

The application provides a kind of UE moving method between RNC, it is possible to increase the success rate of service access.

For achieving the above object, the application adopts the following technical scheme that:

A kind of UE moving method between RNC, including:

RNC is after receiving RAB Assignment Response, if current only one of which RAB, then startup is preset Intervalometer is forbidden in migration；

When RNC receives the measurement report of UE and judgement needs to migrate between RNC, if intervalometer is forbidden in described migration Having been turned on and have not timed out, the most described RNC retransmits to measure to UE and controls message；If described migration forbids that intervalometer does not opens Moving or have timed out, the most described RNC initiates to migrate flow process.

It is preferred that set up the time started to NAS end of signaling according to business, described migration is set and forbids The timing length of intervalometer, it is ensured that described migration forbids that intervalometer is the most overtime before described NAS end of signaling.

As seen from the above technical solution, in the application, RNC after receiving RAB Assignment Response, if Current only one of which RAB, then start default migration and forbid intervalometer；The measurement report of UE is received also at RNC Judgement need between RNC migrate time, if described migration forbids that intervalometer has been turned on and has not timed out, the most described RNC to UE retransmits to measure and controls message；If described migration forbids that intervalometer is not actuated or has timed out, the most described RNC initiates Migrate flow process.By the way, before timer expiry is forbidden in the migration set after business has been set up, do not allow Carry out migrating between RNC, thus avoid when business has set up laggard row service access, lose owing to migrating between RNC Lose the access failure caused, then improve the success rate of service access.

Detailed description of the invention

In order to make the purpose of the application, technological means and advantage clearer, below in conjunction with accompanying drawing to this Shen Please be described in further details.

Being successfully accessed, for current operation, the problem that rate is relatively low, applicant is to migrating between existing RNC and business foundation And access procedure analyzes as follows:

Set up and in access process in current business, as stated in the Background Art, although during business is set up Forbid carrying out migrating between RNC, but business i.e. can carry out after having set up migrating between RNC.But RAB Foundation completes also to have NAS signaling, during as the CS calling procedure of Fig. 3 and Fig. 4 activates with PS PSDP RAB sets up shown in process, has NAS signaling after RAB Assignment Response, as Alerting, Connect, Connect Acknowledge, Activate PDP Context Accept etc..

After business has been set up, start to perform access procedure, if initiating to migrate flow process in access procedure, And there occurs before NAS signalling terminates and migrate unsuccessfully, then this migration unsuccessfully can cause access procedure to occur Failure, consequently leads to the problem that success rate of business insertion is low.

By above-mentioned analysis it can be seen that just because of business set up after, NAS signalling terminate before carry out Migrate between RNC, thus result in the problem that success rate of business insertion is low.Based on this, the application uses Fig. 5 RNC between moving method, thus improve success rate of business insertion, as it is shown in figure 5, the method includes:

Step 501, RNC is after receiving RAB Assignment Response, if current only one of which RAB, Then start default migration and forbid intervalometer.

Here, start migration when only one of which RAB and forbid intervalometer, such that it is able at utmost simplify RNC Process.

Step 502, RNC receives the measurement report of UE, and decides whether to carry out migrating between RNC.If judgement Migrate, then perform step 503, otherwise repeat this step.

RNC, after the measurement report judgement receiving UE needs to carry out migrating between RNC, continues executing with follow-up Process, if judgement is made without between RNC migrating, then continue waiting for receiving the measurement that UE next time reports Report, and make decisions.

Step 503, it is judged that currently whether starting migration forbids intervalometer, if having been started up and having not timed out, then performs Step 504, if not actuated or have timed out, then performs step 505.

Step 504, RNC does not initiate to migrate between RNC, and retransmits measurement report to UE, returns step 502 The measurement report next etc. UE to be received is also adjudicated.

In this step, before timer expiry is forbidden in migration, do not carry out migrating between RNC, thus avoid by RNC Between migrate unsuccessfully cause service access failure.Wherein, migrate and forbid that the timing length of intervalometer presets, Preferably, can set up according to business the time started to NAS end of signaling, described migration has been set Forbid the timing length of intervalometer, thus ensure to migrate before NAS end of signaling to forbid that intervalometer is the most overtime.

Step 505, initiates switching flow between RNC.

Concrete switching flow is same as the prior art, the most just repeats no more.

So far, the method flow shown in Fig. 5 terminates.By said method, the setting time after business has been set up In, forbid migrating between RNC, thus avoid occurring to migrate unsuccessfully to cause service access to be lost before NAS end of signaling Lose, then improve the success rate of service access.

Method shown in above-mentioned Fig. 5 is applied and tests in the rnc, obtain the test result shown in Fig. 6.Specifically Ground, in figure 6, starts " intervalometer is forbidden in migration " after (1) place RAB Assignment Response；In (2) Being in the measurement report receiving UE before NAS signaling does not terminates, RNC needs to initiate to migrate according to measurement report judgement, But owing to having been turned on " intervalometer is forbidden in migration ", so do not initiate to migrate；Retransmit at (3) place to measure and control to UE； The measurement report RNC receiving UE at (4) place needs to initiate to migrate according to measurement report judgement, and now " migration is forbidden Intervalometer " have timed out, so having initiated to migrate, migrate successfully.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention Spirit and principle within, any modification, equivalent substitution and improvement etc. done, should be included in the present invention protect Within the scope of protecting.

Claims

1. the UE moving method between RNC, it is characterised in that including:

Method the most according to claim 1, it is characterised in that set up according to business and started to NAS to believe Make the time till terminating, described migration is set and forbids the timing length of intervalometer, it is ensured that at described NAS end of signaling Front described migration forbids that intervalometer is the most overtime.
