Abstract

The invention discloses a control method of obtaining timing time in a drift radio network controller, which solves the problem of poor system performance and low user service quality caused by obtaining no accurate re-configured timing time in the prior art. The control method includes the following steps: (1) when information from SRNC received by DRNV contains activating time and needs configuration activation in DRNC, DRNC takes a continuous frame number value at the current UE moment from a framing protocol layer; (2) DRNC calculates the activating time in the information and corresponding time of the obtained continuous frame number value and sets up the re-configured timing time from the current moment according to the corresponding time. Thereby, the invention can obtain the accurate re-configured timing time, reduce the possibility of business quality reduction and data loss in new and old configuration switching caused by incorrect timing and improve the system performance and the user service quality.

Description

Obtain the control method of timing in the floating radio network controller

Technical field

The present invention relates to the radio network controller in WCDMA (the Wideband Code Division Multiple Access) system, particularly obtain the control method of timing in the floating radio network controller.

Background technology

The descending on-air radio of the Uu of WCDMA system mouth (logic interfacing between land radio access web and the user) sends strict sequential requirement, system wishes that data are in the orderly transmission of descending aerial strictness, so before data were sent out away, NodeB (base station) wished that the data that RNC (radio network controller) sends also are orderly; And the buffer memory of NodeB itself is limited in one's ability, and another aspect is also in order to reduce the time delay of whole system transfer of data, so NodeB does not wish a large amount of and arrival too early of data that RNC sends; NodeB does not wish that data are next too late yet simultaneously, because too late, may make NodeB that these frame data are had little time to handle, can't be on time from sending in the air, and the result is that these frame data are dropped.Downlink data is at a large amount of buffer memorys of NodeB side or be dropped, and is exactly that speech quality descends or the system transmissions time delay increases to the influence of whole system, has reduced the performance of system.The sequential relationship of all these frames embodies by CFN (Connection Frame Number).The CFN value is and a counter that UE is relevant that its maintenance is carried out in SRNC (service wireless network controller), because Frame all is transparent transmission in DRNC generally, so DRNC generally can't obtain this value.

For many flow processs of RNC, to reshuffle such as wireless link synchronization, it need be at all configuration take-effectives of chien shih when specific, and this just needs activationary time; Since CFN at a UE being fixing unique sometime, so the activationary time in the agreement generally all provides with the CFN value; But generally, in the DRNC be the current CFN value that to know a UE; Though SRNC can bring DRNC activationary time in the signaling of radio layer because DRNC do not know the current time, so in DRNC for some operations that needs activationary time, just deal with relatively difficulty.Common situation all is according to do not influence under the prerequisite of original business, estimate a time, activate new configuration constantly at that and discharge old configuration as far as possible.The time that estimates like this is very inaccurate, generally may cause the decline of loss of user data and voice service quality, has had a strong impact on the performance of system, has reduced offering quality of services for users.

Summary of the invention

For defective and the deficiency that overcomes prior art, the object of the present invention is to provide the control method of obtaining timing in a kind of floating radio network controller, can provide timing accurately for DRNC activates the flow process that reconfigures, and improve systematic function and quality of services for users.

In order to achieve the above object, obtain the control method of timing in a kind of floating radio network controller of the present invention, may further comprise the steps:

(1) receive activationary time is arranged in the message that source radio network controller sends and need activate when disposing when floating radio network controller in floating radio network controller, floating radio network controller is got the Connection Frame Number value of portable terminal current time from frame protocol;

(2) floating radio network controller calculates the activationary time in this message, and obtain the portable terminal current time value from frame protocol, calculate described current time value to the needed relative duration of described activationary time, the timing of reshuffling according to this relative duration setting.

As a further improvement on the present invention, described step (1) is preceding also comprises:

(A) floating radio network controller obtains the Connection Frame Number value of portable terminal in each Transmission Time Interval, and this Connection Frame Number value is stored in frame protocol.

As a further improvement on the present invention, described step (A) is specially:

(A1) floating radio network controller has judged whether downlink data frame at each Transmission Time Interval, if judged result is for being then to enter step (A2); If judged result then enters step (A3) for not;

(A2) floating radio network controller is got the downlink data frame of portable terminal, and unties the Connection Frame Number value that this Frame acquisition is wherein carried, and overrides former Connection Frame Number value in frame protocol, enters step (1);

(A3) floating radio network controller adds up to the connection frame value of original record in the frame protocol, enters step (1).

As a further improvement on the present invention, described step (1) is specially:

(11) floating radio network controller is received the message that source radio network controller is sent, and the cell of detect-message judges whether that according to whether including activationary time in the message needs activate configuration in floating radio network controller, if desired; Then enter step (12); If do not need, then step finishes;

(12) after floating radio network controller is got the Connection Frame Number value of portable terminal current time from frame protocol, enter step (2).

As a further improvement on the present invention, also comprise after the described step (2):

(3) this timing of reshuffling arrives, and floating radio network controller activates new configuration, and discharges old configuration.

After adopting above-mentioned method, owing in the flow process of DRNC activationary time, obtained the datum mark time accurately, and the relative duration of computing activation time and datum mark time, accurately activated the timing of reshuffling, the quality of service that produces when joining descends, loss of data because the inaccurate the old and new of causing that hold opportunity dispose thereby can reduce, and improves the performance and the quality of services for users of system.

Embodiment

In DRNC, the user plane protocol layer relevant with UE has only FP (Frame protocol) protocol layer.Iur FP (the wireless network layer protocol of the logic interfacing user's face between RNC and the RNC) receives the Frame that SRNC sends, directly be transmitted to IubFP (the wireless network layer protocol of the logic interfacing user's face between RNC and the NodeB), directly send to NodeB after it is received; For uplink data frames, directly be transmitted to Iur FP after Iub FP receives equally, directly send to SRNC after it is received.All in SRNC and NodeB, carry out because actual up-downgoing Frame is handled,, can not operate, but these Frames that transmit in real time include the current CFN value of UE frame structure itself so be transparent transmission in the process of this forwarding.

In order to obtain the CFN value of a UE, (Transmission Time Interval, a TTI) interior descending FP Frame selecting UE are untied the CFN value that this Frame acquisition is wherein carried at each Transmission Time Interval.Because UE may maintain a plurality of business simultaneously, transmitting so have a plurality of Frames, but the CFN value that they wherein carry should be the same, so an optional therein frame gets final product at each TTI.If do not have Frame in certain TTI, then the CFN to original record in the frame protocol adds up.If next TTI has obtained the CFN value again from Frame, then override old value in the frame protocol with this new acquisition value.

When DRNC receives in the message that SRNC sends activationary time is arranged, and need in DRNC, activate in the configuration, then DRNC obtains the current CFN value of UE to frame protocol, it is used as this absolute time of UE constantly, calculate its relative duration according to the activationary time in the message then with respect to this absolute time, constantly according to this relative duration timer is set again at this, waits for the arrival of activationary time.Behind the timer expiry, new configuration take-effective, old loss of configuration.

Below in conjunction with accompanying drawing concrete enforcement of the present invention is described in further detail:

As shown in Figure 1, thus the current time reaches the processing procedure of accurate activation configuration more accurately in order to obtain UE in the DRNC;

Step 101, DRNC receives the message of SRNC;

Step 102, DRNC checks the cell of message, finds wherein to comprise activationary time, needs DRNC to activate configuration again, then it needs current time UE correct time point;

Step 103, the CFN value that DRNC gets current time UE to frame protocol, it as current time UE precise time point;

Step 104, in the message of coming according to SRNC with activationary time and from the UE current time value that frame protocol obtains, calculate the needed relative duration of activationary time;

Step 105 is provided with according to this relative duration and activates the length of timer that comes into force, and the duration that described timer comes into force is exactly this duration that calculates;

Step 106, DRNC receives and activates the overtime message that comes into force;

Step 107, DRNC activates new configuration, discharges old configuration.

In a word, adopt this method can obtain more accurate activationary time in DRNC, the quality of service that produces when the inaccurate the old and new that cause that hold owing to opportunity dispose handing-over descends, the problem of loss of data thereby can reduce, and improves the performance of system.
