Description
Technical field
The asynchronous wireless links that the present invention relates to mobile communication system is reshuffled (Unsynchronised RadioLink Reconfiguration) process, particularly the synchronization implementation method of the base station asynchronous wireless links reconfiguration course in the third generation mobile.
Background technology
In the third generation mobile system, as TD SDMA (TD-SCDMA) system, radio link reconfiguration is a very important flow process for the third generation mobile system, and the increase that relates to customer service such as deletes at work.Radio link reconfiguration is initiated by RNC (Radio NetworkController, radio network controller), comprises that synchronised radio link reconfigure and asynchronous wireless links reshuffle.
For asynchronous wireless links is reshuffled; because the restriction of physical resource itself; can cause the radio link reconfiguration failure, and according to asynchronous flow process of reshuffling, system can switch directly; for whole system; the base station handoff failure, in most cases, owing to relate to whole base station system; so rollback difficulty behind the asynchronous wireless links reconfiguration failure, the user usually can be deleted.
The asynchronous wireless links of the Iub mouth of RNC is reshuffled normal flow as shown in Figure 1:
Usually under following situation, system can initiate the asynchronous flow process of reshuffling:
Transmission channel is revised;
Transmission channel increases;
The transmission channel deletion;
Physical channel is revised (FDD, Frequency Division Duplexing (FDD));
CCTRCH (CCTrCH Coded Composite Transport Channel, Code Composite Transport Channel) revises (TDD, time division duplex);
CCTRCH deletes (TDD).
As shown in Figure 1, send the asynchronous wireless links reconfiguration request message to the base station, send between the response message to RNC, do not have other any message to the base station at RNC.
Base station response message has two kinds:
Asynchronous reshuffling successfully;
Asynchronous reconfiguration failure, as shown in Figure 2.
Reason at the asynchronous reconfiguration failure of base station side roughly has: other reasonses such as network layer reason, transport layer reason, control overload.
Because in asynchronous reshuffling, the new configuration in the system requirements reconfiguration message comes into force at once, and between each subsystem of inside of base station owing to the relation of having levels, so if certain layer of reconfiguration failure, then other each layer rollback difficulties.For the base station, then mean asynchronous reconfiguration failure, and be expendable.For whole access network, because the irrecoverable property of base station asynchronous reconfiguration failure will cause the user to be released.
Be illustrated in figure 3 as the Message Processing schematic diagram between each layer of inside of base station.Because each internal system effect difference for ease of understanding, is used abstract block representation herein.
As shown in Figure 3, receive the asynchronous wireless links reconfiguration request message of RNC transmission when the base station after, should asynchronous reconfiguration request message send to user's face and base band successively by chain of command, treat base band to user's face respond asynchronous reshuffle the response success message after, user's face responds the asynchronous response success message of reshuffling to chain of command again, the base station just sends the asynchronous response success message of reshuffling to RNC.
Among Fig. 3, for user's face and the base band in the abstract block diagram, if user's face is after receiving the chain of command reconfiguration message, user's face is directly switch to the new configuration of reshuffling, to newly dispose simultaneously and send to base band and switch, in case the baseband switching failure, then the configuration of user's face can't rollback, this directly causes base station asynchronous reconfiguration failure, and the base station is difficult to rollback.
After if user's face is received the chain of command reconfiguration message, user's face elder generation reservation message sends to base band with asynchronous reconfiguration information, responds etc. base band, if respond successfully then user's face switches to new configuration.If the asynchronous reconfiguration failure of base band then returns asynchronous reconfiguration failure to chain of command, and keep old configuration.Although in this case, can be relatively easy to realize the rollback of reconfiguration failure, in this case same, if user's face is received the success response of reshuffling of base band, but the handoff failure of user's face own, base band is difficult to rollback equally.
At present in existing technology, also there is not a cover unified method at inside of base station, prevent the situation that locking system can't rollback behind asynchronous reconfiguration failure, this causes the user by not solution of release problem unusually, makes that also the fault freedom of system is lower.
Summary of the invention

The base station receives the asynchronous wireless links reconfiguration request message from radio network controller;
The base stations control face is according to described reconfiguration request message, and the parameter of Radio Link itself, constructs a synchronised radio link reconfigure and prepares message;

Send described synchronised radio link reconfigure by base stations control towards each layer of inside of base station and submit message to, and handle respectively by described each layer;
Success message is reshuffled to radio network controller response asynchronous wireless links in the base station.
Wherein judge in the step of described each layer to the result of described preparation message,, then send asynchronous wireless links reconfiguration failure message to radio network controller if determine the processing failure of any one deck at described base stations control face.
The present invention also provides another kind of technical scheme, comprises the steps:
The base station receives the asynchronous wireless links reconfiguration request message from radio network controller;
The base stations control face is according to described reconfiguration request message, and the parameter of Radio Link itself, constructs a synchronised radio link reconfigure and prepares message;
Send described synchronised radio link reconfigure by base stations control towards each layer of inside of base station and prepare message, and handle respectively by described each layer;
The base stations control face is judged the result of described each layer to described preparation message, after definite each layer handled all successes, reshuffles success message to radio network controller response asynchronous wireless links, and constructs a synchronised radio link reconfigure and submit message to;
Send described synchronised radio link reconfigure by base stations control towards each layer of inside of base station and submit message to, and handle respectively by described each layer.
Wherein judge in the step of described each layer to the result of described preparation message,, then send asynchronous wireless links reconfiguration failure message to radio network controller if determine the processing failure of any one deck at described base stations control face.
Because the synchronization implementation method that the present invention provides asynchronous wireless links to reshuffle in base station side, wireless link synchronization is prepared message, wireless link synchronization is submitted message to by generating in the inside of base station simulation, thereby reshuffles synchronization process at inside of base station realization asynchronous wireless links.After synchronization process, even the accurate failure of wireless link synchronization in handle the base station, the base station is rollback very easily also, and under wireless link synchronization was ready to complete situation, switching itself can not failed simultaneously.Therefore, the application of the invention can significantly reduce system's rollback difficulty that asynchronous wireless links failure brought, the probability that customer service is deleted unusually, has strengthened system survivability greatly.
