Description
Technical field
The present invention relates to wireless communication field, relate in particular to the measurement changing method of a kind of WCDMA (Wideband CodeDivision Multiple Access Wideband Code Division Multiple Access (WCDMA)) system to GSM (Global System ForMobile Communications global system for mobile communications) system.
Background technology
The WCDMA system is a kind of of 3-G (Generation Three mobile communication system) (3G), in the area of the adjacent covering in sub-district of the sub-district of this system and gsm system, in order to realize the smooth transition of customer service, has introduced between the system between WCDMA and GSM and has switched.Specifically be when the user after 3G sub-district initiation business, along with gradually mobile meeting away from this 3G sub-district near the GSM sub-district, in this case, need carry out the switching of gsm system, otherwise may cause conversation loss.And the GSM adjacent area of 3G sub-district has a plurality of under many circumstances, CS of WCDMA system (Circuit Service circuit domain business) or PS (Packet Service packet switch domain service) need the GSM adjacent area is measured before switching to gsm system, decide specifically according to the measurement report of UE (User Equipment subscriber equipment) and to carry out switching between system to which sub-district, if the quality of certain GSM adjacent area is enough good, then SRNC (Serving Radio Network Controller service wireless network controller) order UE switches to this adjacent area, and user's business can continue like this.Because multiple GSM frequency range and depositing under the network environment of complexity, as GSM900 (Global System For Mobile Communications at900MHZ), DCS1800 (Digital Cellular Network at 1800MHz digital cellular network, frequency range is at Global System for Mobile communications), PCS1900 (Personal Communication Systemat 1900MHZ PCS Personal Communications System, frequency range is at the gsm system of 1900MHz) etc., UE is to measurement capability (referring to whether up-downgoing needs to open compact model and the carry out system's measurements) difference of different GSM frequency ranges, needs SRNC to take all factors into consideration according to the general status of neighbor cell configuration between the ability of UE and system when order UE carries out system's measurements.
GSM adjacent area type with the 3G sub-district is that GSM900 and DCS1800 are that example is carried out, because UE to different GSM frequency range measurement capability differences, may need start compact model to certain GSM frequency range and measure.As shown in Figure 1, present measurement changing method of the prior art is: dropped to certain thresholding when UE reports the carrier frequency quality of this 3G sub-district, if the measurement meeting of not opening the GSM adjacent area causes call drop owing to the deterioration of this carrier frequency, SRNC order this moment UE starts the measurement to the GSM adjacent area, but before opening system's measurements, need to consider the tenability of UE to the GSM nearby region measurement, as long as the measurement capability of UE need need start compact model to any measurement among GSM900 and the DCS1800, then when carrying out system's measurements, start compact model, and the GSM sub-district of GSM900 and DCS1800 type is all joined in the GSM Neighboring Cell List of system's measurements; If the measurement capability of UE does not need to start compact model for any measurement among GSM900 and the DCS1800, then do not open compact model, direct command UE starts the measurement to the GSM adjacent area, the adjacent area that comprises GSM900 and DCS1800 in the GSM Neighboring Cell List, handover event between the UE reporting system then, SRNC order UE switches to corresponding GSM adjacent area.
There is following problem in existing WCDMA system to the measurement changing method of gsm system: 1, because UE may not need open compact model measures and can find the sub-district that can switch, there is no need these sub-districts are started the measurement of compact model, prior art is not distinguished the GSM cell type when measuring, and causes unnecessary overhead.2, UE may fail in return measurement control, causes follow-up call drop.Reason is may have only a kind of adjacent area type to need compact model to come the executive system measurements in GSM900 and two kinds of GSM adjacent areas of DCS1800, as long as measure and when having a kind of GSM adjacent area to need compact model to measure, just carry out compact model in the prior art, caused and also used compact model to measure to the GSM adjacent area that does not need to carry out the compact model measurement, such contradiction may be failed UE in return measurement control.3, the unlatching compact model interweaves to user's quality of service, physical layer, rate-matched, and the power control and treatment all can produce certain influence, and the processing of prior art may bring the unnecessary harmful effect to system.

Embodiment
The invention will be further described in conjunction with embodiment for the contrast accompanying drawing below.
Embodiment one: measurement changing method of the present invention is according to GSM frequency range difference, the GSM sub-district that the 3G sub-district is contiguous is measured the GSM frequency range by UE not to be needed compact model and needs compact model to divide into the first frequency band GSM system sub-district and the second frequency band GSM system sub-district, it is GSM900 that first frequency range can be set, second frequency range is DCS1800, it is DCS1800 that first frequency range perhaps is set, and second frequency range is GSM900; It is GSM900 that first frequency range also can be set, and second frequency range is PCS1900, and it is PCS1900 that first frequency range perhaps is set, and described second frequency range is GSM900.
As shown in Figure 2, the process of this schematic diagram may further comprise the steps:
1, the gsm system sub-district is divided into the first frequency band GSM system sub-district and the second frequency band GSM system sub-district by the measurement capability of UE, the first thresholding D1 and the second thresholding D2 of service wireless network controller setting and sending measuring control give subscriber equipment; The first thresholding D1 is higher than the second thresholding D2;
2, the WCDMA carrier frequency quality of subscriber equipment dynamic monitoring self use; When the carrier frequency quality is higher than the first thresholding D1, jump to step 3; When the carrier frequency quality is between the first thresholding D1 and the second thresholding D2, jump to step 4; When the carrier frequency quality is lower than the second thresholding D2, jump to step 5;
3, service wireless network controller is not handled, and returns step 2;
4, service wireless network controller control subscriber equipment carries out kinetic measurement to the first frequency band GSM system sub-district, and the first frequency band GSM system sub-district that whether judgement is switched and switched to according to the measurement situation, service wireless network controller control subscriber equipment is finished switching, finishes;
5, service wireless network controller control subscriber equipment carries out kinetic measurement to the second frequency band GSM system sub-district, and the second frequency band GSM system sub-district of whether switching and switching to according to the situation judgement of measuring, service wireless network controller control subscriber equipment is finished switching, finishes.
Can see that the WCDMA carrier frequency quality that this method is used by user equipment monitors self according to the comparative result of the WCDMA carrier frequency quality that monitors and the first thresholding D1 and the second thresholding D2, is selected to operate accordingly.If be higher than the first thresholding D1, then SRNC does not process, and UE continues monitoring WCDMA carrier frequency quality.If between the first thresholding D1 and the second thresholding D2, begin measurement to the first frequency band GSM system sub-district, whenever measure the GSM carrier frequency quality of a gsm system sub-district, whether the GSM carrier frequency quality of adjudicating this sub-district according to the measurement situation by SRNC reaches the switching requirement, if reach, then switch to this sub-district, finish by SRNC control UE; If do not reach the switching requirement, continue the first frequency band GSM system sub-district is measured.If being WCDMA carrier frequency quality, monitoring result is lower than the second thresholding D2, begin measurement to the second frequency band GSM system sub-district, whenever measure the GSM carrier frequency quality of a gsm system sub-district, whether the GSM carrier frequency quality of adjudicating this sub-district according to the measurement situation by SRNC reaches the switching requirement, if reach, then switch to this sub-district, finish by SRNC control UE; If do not reach the switching requirement, continue the second frequency band GSM system sub-district is measured.As seen, all be a kinetic measurement process for the measurement of two frequency band GSM system sub-districts, when not switching incident, underway all the time for the measuring process of this frequency range.
Same, UE also is a dynamic process for the monitoring of the WCDMA carrier frequency quality that self uses, and does not only proceed when returning step 2 when SRNC does not process, and monitoring is operated and also carried out in the kinetic measurement process of step 4 and 5.When monitoring result changes, be that this WCDMA carrier frequency quality that monitors is different with the comparative result of last time with the comparative result of the first thresholding D1 and the second thresholding D2, if produced the kinetic measurement operation in last time handling, for example last time monitoring result is carry out step 4, also comprises the step of turn-offing last time kinetic measurement operation so before this is handled.Promptly for example last time monitoring result be carry out step 4, this monitoring result is carry out step 5, then the beginning step 5 the kinetic measurement to the second frequency band GSM system sub-district before, at first turn-off kinetic measurement to the first frequency band GSM system sub-district.
The present invention adopts non-compact model according to the measurement capability of UE to the kinetic measurement of the first frequency band GSM system sub-district, and compact model is adopted in the kinetic measurement of the second frequency band GSM system sub-district.Thus, select different measurement patterns by WCDMA carrier frequency quality.Switch decision in step 4 and the step 5 is carried out according to the measurement report of UE by SRNC.
Embodiment two: as shown in Figure 3, the flow process of present embodiment is as follows:
Step 201, UE initiates professional in the 3G sub-district, after professional the foundation, SRNC issues the inter-frequency measurement control gate and is limited to UE, measure control gate and limit the use of, initial measurement control gate is set is limited to the first thresholding D1 in judge whether to report SRNC to initiate to measure for subscriber equipment with request;
Step 202 judges whether UE reports the WCDMA carrier frequency deterioration of self using to reach or be lower than the first thresholding D1, if do not report, SRNC does not process, and repeats this step;
Step 203, if UE reports this carrier frequency to reach or is lower than the first thresholding D1 to SRNC, SRNC measures and adopts non-compact model to the control of UE transmitting system measurements, the GSM cell list in system's measurements control has comprised the adjacent area of a plurality of GSM900;
Step 204, SRNC controls thresholding with inter-frequency measurement and is revised as the second thresholding D2, and the second thresholding D2 is lower than the first thresholding D1;
Step 205, judge whether UE reports handover event between the system of GSM900 sub-district, be whether to find GSM carrier frequency quality to satisfy in the measuring process to switch the gsm system sub-district that requires, if do not report SRNC not process, continue the gsm system sub-district of measure GSM 900 frequency ranges, and jump to step 207;
Step 206, if handover event between the UE reporting system, SRNC order UE switches to corresponding GSM adjacent area, promptly satisfies and switches the gsm system sub-district that requires, handoff procedure finishes;
Step 207 judges that whether UE reports the deterioration of this carrier frequency to reach or be lower than the second thresholding D2, if do not report, then returns step 205;
Step 208, if UE reports the deterioration of this carrier frequency to reach or is lower than the second thresholding D2, system's measurements control in the SRNC release steps 203, order UE starts compact model and new system's measurements control, and the GSM cell list in new system's measurements control has comprised the GSM adjacent area of a plurality of DCS1800;
Step 209 judges whether UE reports incident between the system of DCS1800 sub-district, if do not report, SRNC does not process; Continue to measure the gsm system sub-district of DCS1800 frequency range; If report then go to step 206, UE switches to corresponding GSM adjacent area by the SRNC order, and handoff procedure finishes;
Said process adopts non-compact model for the measurement of GSM900, and compact model is adopted in the measurement of DCS1800, and this only is to be first frequency range with GSM900 in the present embodiment, and DCS1800 is second frequency range, and as previously mentioned, first frequency range and second frequency range are not to be defined in this.Can first frequency range be DCS1800 also, second frequency range be GSM900 or the like.
The specific embodiment of the invention two consider UE may return measurement the control failure, according to UE the tenability of GSM nearby region measurement is divided into two groups to the GSM adjacent area, list in different system's measurements control messages, measure respectively.When the carrier frequency deterioration of 3G sub-district during to first thresholding, directly open system's measurements, the GSM Neighboring Cell List that comprises in system's measurements control is the sort of GSM adjacent area type that UE measures does not need compact model, if UE reports handover event between the system of such GSM adjacent area subsequently, then order UE to switch in such GSM adjacent area, switching flow finishes between system; If not having the carrier frequency quality of reporting events between the system of such adjacent area and 3G sub-district continues to worsen and reaches second thresholding, at this moment discharge system's measurements earlier with front opening, start compact model then and open system's measurements again, the GSM Neighboring Cell List that comprises in this system's measurements control is the sort of GSM adjacent area type that the UE measurement needs compact model.Embodiment two has at first been opened the measurement to first frequency range, just open measurement afterwards to second frequency range, this is based on avoids starting the purpose that compact model is measured as far as possible, because might just can find the gsm system sub-district that meets switching condition and can carry out switching between system the measurement of first frequency range, avoid embodiment once may directly having opened the compact model measurement to D2 in the carrier frequency deterioration.
The present invention distinguishes by UE the GSM adjacent area of WCDMA system to the difference of nearby region measurement ability, when opening measurement, once only the GSM sub-district of a frequency range is measured, thus, can save overhead, also avoid the measurement control failure that may cause, reduced cutting off rate because UE is different to the measurement capability of the gsm system sub-district of different frequency range; Preferentially carry out system's measurements of non-compact model and can save system resource to a certain extent, can reduce the harmful effect that compact model brings to system, thereby reduce risk of dropped calls, promoted the overall operation performance of 3G system.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention, and modification or distortion for the present invention's design also all belong to protection scope of the present invention.
