Abstract
The present invention relates to a method for processing measurement information in a global system for mobile communications (GSM), which comprises the steps that on an activated dedicated channel, BTS carries out up run measurement to various signals of MS on the dedicated channel in a measuring period according to a frame structure on a wireless interface to obtain an up run measured value; simultaneously, after occupying a channel, MS carries out down run measurement to various signals of BTS in the same measuring period to obtain a down run measured value and reports a result to the BTS. The present invention is characterized in that BTS preprocesses the measurement information obtained in the measuring period to reduce the interface signaling load between BTS and BSC to generate a measuring result message, and finally, the preprocessed measuring result message is outputted to BSC.
Description
The present invention relates in global mobile communication (GSM) system metrical information be carried out pretreated method.
Referring to Fig. 1, in existing gsm system, measurement report utilizes each possible chance to go up at the SACCH of dedicated channel SDCCH (Separate Dedicated Control Channel) or TCH (Traffic Channel) (channel associated signalling channel at a slow speed) by mobile station MS and sends, and per second once at least.In the basic scheme of the ETSI of European Telecommunication Standard Institute regulation, on a dedicated channel that activates, base transceiver station BTS carries out out-hole run according to the frame structure on the wave point (approximately per second twice) in measuring period to the various signals of the MS on this dedicated channel, obtain the out-hole run value, simultaneously, MS carries out down-run survey to the various signals of BTS in same measuring period after having taken a channel, obtain the down-run survey value, and the result is reported BTS (because complicated radio conditions, this result might not guarantee correctly to be sent to BTS).BTS to the processing of various measured values is: (waiting for the fixing time less than measuring period again) detected whether receive a new down-run survey value after BTS at first produced an out-hole run value, if then the result that up-downgoing is measured sends to base station controller BSC with a measurement result message; If also do not receive the down-run survey value of MS, BTS directly send BSC with up measured value with a measurement result message.All these data are handled by BSC then, through-put power control are provided and switch to prepare.
There is shortcoming in above-mentioned standard scheme, be exactly that measurement result on the SACCH causes very big signaling load when being sent to BSC on BTS/BSC interface (Abis mouth), and wherein most signaling load causes significant wastage less than effect to the bandwidth on the Abis mouth.
The object of the present invention is to provide the processing method of metrical information in a kind of gsm system, this method not only meets the GSM related specifications, and can reduce Abis message and make load.
To achieve these goals, the present invention, it is the processing method of metrical information in a kind of gsm system, it comprises the following steps: in gsm system, after having activated a dedicated channel, base transceiver station carries out out-hole run according to the various signals to the travelling carriage on this dedicated channel in measuring period of the frame structure on the wave point, obtain the out-hole run value, simultaneously, travelling carriage carries out down-run survey to the various signals of base transceiver station in same measuring period after having taken a dedicated channel, obtain the down-run survey value, and the result is reported base transceiver station, be characterized in: what base transceiver station will obtain in above-mentioned measuring period comprises, the metrical information of down-run survey value reduces the preliminary treatment of base transceiver station/base station controller interface signaling load, generates the measurement result message; Export pretreated measurement result message to base station controller at last.
The processing method of metrical information in above-mentioned a kind of gsm system, wherein, preprocess method is: be discarded in the uplink and downlink measured value that dedicated channel activates the back starting stage.
The processing method of metrical information in above-mentioned a kind of gsm system, wherein, preprocess method is: when arrive in each measuring period after the starting stage, judge at first whether base transceiver station has received the down-run survey value:, then produce current down-run survey value by handling according to history if do not receive the down-run survey value; If received the down-run survey value, then directly use; And then, judge whether need to report preliminary treatment measurement result message:, further judge whether to carry out layering and switch if do not need to report according to reporting the frequency indication: if, then reporting the preliminary treatment measurement result, indication inside need be switched; If not, then do not report any message to base station controller; Report if desired, then report preliminary treatment measurement result message, and indicate whether within it and need switch.
The processing method of metrical information in above-mentioned a kind of gsm system, wherein, preprocess method is: remove the nuisance parameter in the described metrical information; Parameter useful in the metrical information filled up lose measured value, remove the measured value burr.
Adopt above-mentioned method, that is: introduced scheme in the agreement, in BTS, more handle, reduce the Abis interface amount of redundant information, thereby reduce BTS and BSC inside and the information flow between them, reach the saving operation cost with circuit switching.
The present invention is further illustrated below in conjunction with the embodiment of the invention and accompanying drawing.
Fig. 1 is the schematic diagram that has the metrical information processing procedure that provides in the standard now;
Fig. 2 is the schematic diagram of metrical information processing procedure in the gsm system of the present invention.
As shown in Figure 2, the processing method of metrical information in a kind of gsm system, it comprises the following steps: on a dedicated channel that activates, BTS carries out out-hole run according to the various signals to the MB on this dedicated channel in measuring period of the frame structure on the wave point, obtain the out-hole run value, simultaneously, MS carries out down-run survey to the various signals of BTS in same measuring period after having taken a channel, obtain the down-run survey value, and the result is reported BTS, be characterized in: BTS will receive in above-mentioned measuring period that metrical information reduces the preliminary treatment of BTS/BSC interface signaling load, generate the measurement result message; Export pretreated measurement result message to BSC at last.
The processing method of metrical information in the above-mentioned gsm system, wherein preprocess method is: be discarded in the uplink and downlink measured value that dedicated channel activates the back starting stage.
Measurement report transmits on SACCH, and its main channel may be SDCCH and TCH.For TCH,, lose the initial several measurement reports of channel flow is not had much affect because life cycle is longer.For SDCCH, its particularity makes and reduces a lot of flows like this.Some basic conditions of SDCCH are as follows:
The most common situation: the i.e. general SDCCH-that we see under the normal condition〉situation of TCH.The life cycle of SDCCH channel is generally in 3 seconds in this case.Begin to calculate from the channel activation, the measurement report number is at 4～6 till discharging to channel.Lose initial several measurement reports under this situation without any relation (even think terrifically not reporting measurement reports all it doesn't matter).
Direct assignment situation (more rare): but in the sub-district, do not have under the TCH distribution condition, and BSC directly assigns to MS in another sub-district by the form of switching according to measurement report.In this case, if in direct assignment length of timer, do not receive the measurement report of MS, will cause that channel discharges and causes call drop.The life cycle of SDCCH channel is generally also about 3 ~ 5 seconds in this case.BSC only needs to receive an effective measurement report in the life cycle of SDCCH channel just can finish this function, so not influence of several measurement reports before losing.
Switch instances (not occurring substantially): the life cycle of SDCCH in particular cases may be kept long time at some.At this moment may occur in the switching on the SDCCH.This situation and TCH do not have difference, not influence of several measurement reports before losing.
So, only channel initially need be set up the measurement report of back in 2 ~ 3 seconds in base station side and be abandoned, the Abis message that each SDCCH/8 channel can reduce about 2KBits/ second under peak condition makes load.
In the processing method of metrical information, preprocess method wherein also can adopt the reduction measurement report to report frequency and hierarchical control to switch in the above-mentioned gsm system, and its process is:
When arrive in each measuring period after the starting stage, judge at first whether BTS has received the down-run survey value:
If do not receive the down-run survey value, then produce current down-run survey value by handling according to history;
If received the down-run survey value, then directly use;
And then according to reporting the frequency indication, judge whether need to report preliminary treatment measurement result message:
If do not need to report, for avoid some in emergency circumstances network side do not obtain measurement result and can not in time initiate to switch the consequence that causes the travelling carriage call drop, further judge whether and need switch:
If, then reporting the preliminary treatment measurement result, indication inside need be switched;
If not, then do not report any message to base station controller;
Report if desired, then report preliminary treatment measurement result message, and indicate whether within it and need switch.
In the processing method of metrical information, preprocess method wherein also can adopt simplifies the measurement result content in the above-mentioned gsm system, and its process is:
Remove the nuisance parameter in the described metrical information;
Parameter useful in the metrical information filled up lose measured value, remove the measured value burr.
