Embodiment
The characteristic of microcellulor network to allow mobile terminal UE seamlessly switch to Target cell from current area, and wherein current area and Target cell can be homogeneous-frequency adjacent-domain in homologous ray or alien frequencies adjacent area, can certainly be different system adjacent cell.As shown in Figure 1, mobile terminal moves to the edge of LTE community A, suppose that the condition of community A intra-system handover (described intra-system handover refers to that mobile terminal switches between the different districts belonging to same system) is homogeneous-frequency adjacent-domain 3 decibels (dB) (for homogeneous-frequency adjacent-domain) higher than current area level, and mobile terminal does not detect the homogeneous-frequency adjacent-domain meeting this switching condition always; After the signal level of Deng Dao community A drops to certain thresholding, in order to ensure business normally carry out be necessary trigger isosystem measurement, mobile terminal triggers A2 event report, then mobile terminal carries out different system adjacent cell measurement according to the measurement instruction of base station, and different system adjacent cell covers better, mobile terminal measures the community meeting the different system of switching condition very soon, and carries out cell merge.
Because in prior art, homologous ray nearby region measurement controling parameters may arrange unreasonable, cause the generation that some unnecessary different system cells switch.Various embodiments of the present invention are in order to reduce this unnecessary switching, a solution is provided namely to judge whether to there is the homologous ray adjacent area met the demands by the homologous ray nearby region measurement controling parameters reducing current area, and record the number of times of unnecessary different system cell switching accordingly, the base station such as LTE base station of current system is when there is the good community of quality in native system, carry out the adjustment of different system adjacent cell Survey control parameter, as postponed the tangential different system of mobile terminal etc., thus increase the probability of the tangential homologous ray adjacent area of mobile terminal.Various embodiments of the present invention realize than being easier to, and utilize existing procedure, without the need to passing through RAN information management (RANinformationmanagement between system; Be called for short: RIM) carry out information interaction.
Fig. 2 is the schematic flow sheet that the present invention reduces method one embodiment that unnecessary different system cell switches, and as shown in Figure 2, the method comprises the steps:
The base station of step 200, current area receive that mobile terminal sends for after showing the event report that needs to carry out isosystem measurement, Survey control message is sent to described mobile terminal, described Survey control message comprises different system adjacent cell Survey control parameter, and the homologous ray nearby region measurement controling parameters under newly-increased measurement mark ID; Homologous ray nearby region measurement controling parameters under described newly-increased measurement ID is easier than preset homologous ray nearby region measurement controling parameters meets intra-system handover condition, and the homologous ray nearby region measurement controling parameters under described newly-increased measurement ID is not used in intra-system handover judgement, intra-system handover judgement still uses described preset homologous ray nearby region measurement controling parameters;
Mobile terminal resides in current area and carries out in the process of wireless traffic, due to the mobility of mobile terminal, it progressively may move to the marginal position of current area, now due to the limited coverage area of current area, signal strength signal intensity at its marginal position place can lower, therefore the signal quality of current area can be caused can not to meet pre-provisioning request, need to carry out measuring peripheral cell, carry out cell merge with the mode request of the base station reporting measurement reports to current area.
In the process that current cell signal quality reduces, mobile terminal can constantly be measured the homologous ray adjacent area of current area, will meet the adjacent zone information reporting of intra-system handover condition (namely meeting preset homologous ray nearby region measurement controling parameters) to base station.Homologous ray nearby region measurement controling parameters described herein is that mobile terminal is handed down in advance in base station, and wherein homologous ray adjacent area can comprise homogeneous-frequency adjacent-domain, also can comprise alien frequencies adjacent area.Various embodiments of the present invention are only described for homogeneous-frequency adjacent-domain, are certainly not limited thereto.
The switching condition of such as homogeneous-frequency adjacent-domain is event A3(EventA3, comprise the trigger condition of carrying out homogeneous-frequency adjacent-domain switching, triggering this event when a triggering condition is met and carry out intra-system handover) thresholding is 3dB, the triggered time (TimetoTrigger, TTT) is 320ms.If mobile terminal reports base station after the homogeneous-frequency adjacent-domain meeting above-mentioned default switching condition being detected, mobile terminal just can be switched on this homogeneous-frequency adjacent-domain by base station.If base station does not receive the A3 measurement report of mobile terminal reporting, then show that the periphery of current area does not have to meet the homogeneous-frequency adjacent-domain of above-mentioned switching condition.Know that the signal quality of current area can trigger A2(EventA2 when mobile terminal detects, comprise the trigger condition of carrying out different system adjacent cell switching, triggering this event when a triggering condition is met and carry out different systematic evaluation) after event, mobile terminal sends the measurement that A2 Event Report Request carries out different system cell to base station.Base station receive that mobile terminal sends for after showing the event report that needs to carry out isosystem measurement, send Survey control message to mobile terminal.
In the embodiment of the present invention, Survey control message comprises different system adjacent cell Survey control parameter and the newly-increased homologous ray nearby region measurement controling parameters measured under mark ID, wherein, described homologous ray nearby region measurement controling parameters can comprise homogeneous-frequency adjacent-domain Survey control parameter, also can comprise alien frequencies nearby region measurement controling parameters, or the two comprises simultaneously.The embodiment of the present invention is described for homogeneous-frequency adjacent-domain Survey control parameter.The homogeneous-frequency adjacent-domain Survey control parameter of newly-increased measurement ID is easier than preset homogeneous-frequency adjacent-domain Survey control parameter meets intrasystem switching condition.Described preset homogeneous-frequency adjacent-domain Survey control parameter is send for before showing the event report that needs to carry out isosystem measurement at mobile terminal, is received by mobile terminal.The switching condition (also can be called: the switching condition of predetermined homogeneous-frequency adjacent-domain) that switching condition corresponding to the newly-increased homogeneous-frequency adjacent-domain Survey control parameter measuring ID is more corresponding than preset homogeneous-frequency adjacent-domain Survey control parameter is easier to be satisfied.Owing to not detecting according to the switching condition of the homogeneous-frequency adjacent-domain of presetting before the homogeneous-frequency adjacent-domain satisfied condition, the homogeneous-frequency adjacent-domain Survey control parameter reset of the current area under newly-increased measurement ID is issued in the embodiment of the present invention, and the homogeneous-frequency adjacent-domain Survey control parameter reset is easier than preset homogeneous-frequency adjacent-domain Survey control parameter meets cell merge condition, object is the detection chance increasing homogeneous-frequency adjacent-domain, and the homogeneous-frequency adjacent-domain of the switching condition preset before making to meet can meet the lower switching condition reset.Give an example, described same frequency handoff threshold can for meeting the thresholding of the measurement event defined in agreement 3GPPTS36.331, the such as thresholding etc. of A3 event.For example, the switching condition of homogeneous-frequency adjacent-domain before preset is A3 event thresholds be 3dB, TTT is 320ms, then the A3 event thresholds comprised in Survey control message of this configuration is 2dB, TTT is 160ms.Because switching condition reduces, more homogeneous-frequency adjacent-domain will become the alternative of Target cell.
The wherein said homogeneous-frequency adjacent-domain Survey control parameter be included in Survey control message corresponds to a newly-increased measurement ID.That is, base station is after issuing the homogeneous-frequency adjacent-domain Survey control parameter reset, mobile terminal place has two parallel A3 events simultaneously, what the parameter of one of them A3 event adopted is preset homologous ray nearby region measurement controling parameters, and what the parameter of newly-increased A3 event adopted is the homogeneous-frequency adjacent-domain Survey control parameter reset.The measurement ID that two parallel A3 events are corresponding different, also just says it is that the homogeneous-frequency adjacent-domain Survey control parameter reset does not have any impact to preset homologous ray nearby region measurement controling parameters, and the two is also deposited.After any one A3 event is triggered, mobile terminal all can reporting measurement reports.Homologous ray nearby region measurement controling parameters under the newly-increased ID of measurement is not used in intra-system handover and adjudicates, and it is only for the collection to unnecessary different systematic evaluation information; And intra-system handover decision networks side still uses preset homologous ray nearby region measurement controling parameters.
The base station of step 201, current area receives measurement report that described mobile terminal returns and described mobile terminal is successfully switched to the different system adjacent cell meeting described different system adjacent cell Survey control parameter from current area, then this switched to be recorded as once non-essential different system cell and to switch; To be described mobile terminal measure according to the homologous ray nearby region measurement controling parameters under described newly-increased measurement ID described measurement report, reports when homologous ray nearby region measurement controling parameters under having at least a homologous ray adjacent area to meet described newly-increased measurement ID;
After base station issues described Survey control message to mobile terminal, mobile terminal is measured according to the homologous ray nearby region measurement controling parameters (for homogeneous-frequency adjacent-domain Survey control parameter) under newly-increased measurement ID wherein, if there is at least one homogeneous-frequency adjacent-domain satisfied condition, measurement report is reported base station.If this measurement report comprises the cell measurement information of at least one homogeneous-frequency adjacent-domain, then show still there is the requirement that homogeneous-frequency adjacent-domain can meet the basic service quality of mobile terminal in current system herein, substantially can provide service for it.In the embodiment of the present invention, mobile terminal carries out the process of homologous ray nearby region measurement reporting measurement reports, can carry out before this mobile terminal to switch to the Target cell of different system from current area, can carry out behind the Target cell of different system at successful switch, that is it does not affect normal cell merge flow process yet.If carry out before different systematic evaluation, measurement report directly can report the base station of current system, if carry out after switching completes, then measurement report is forwarded by different system base-station.Wherein, the Target cell of described different system should for meeting the different system adjacent cell of different system adjacent cell Survey control parameter.
When mobile terminal be successfully switched to the different system adjacent cell that meets different system adjacent cell Survey control parameter from current area and the base station of current system receives the measurement report that mobile terminal returns, this different systematic evaluation is recorded as once non-essential different system cell and switches by the base station of current system.To be mobile terminal measure according to the newly-increased homologous ray nearby region measurement controling parameters measured under ID described measurement report, reports when homologous ray nearby region measurement controling parameters under having at least a homologous ray adjacent area to meet described newly-increased measurement ID.
" non-essential different system cell switches " described in various embodiments of the present invention specifically refers to, measurement report due to homologous ray adjacent area shows in the system at mobile terminal place before cell merge, there is the basic service requirement that homogeneous-frequency adjacent-domain and/or alien frequencies adjacent area can meet mobile terminal, mobile terminal can be switched in different system adjacent cell originally, and continues to reside in native system community (homogeneous-frequency adjacent-domain or alien frequencies adjacent area); But because arranging of intra-system handover condition is higher, mobile terminal not using the homologous ray adjacent area in the measurement report of homologous ray adjacent area as the Target cell of carrying out cell merge, but be in fact switched in different system cell according to existing procedure, therefore think that this time switching is once " non-essential switching ".
The total degree of non-essential different system cell switching is added up in the base station of step 202, current area in predetermined period, if judge to know the update condition meeting and preset according to the total degree that described non-essential different system cell switches, then different system adjacent cell Survey control parameter is upgraded; Different system adjacent cell Survey control parameter through upgrading is more more difficult than the described different system adjacent cell Survey control parameter issued before meets cell merge condition.
The total degree that the non-essential different system cell that appearance is added up in base station in predetermined period switches, statistic processes can be carried out for multiple different mobile terminal, such as add up all mobile terminals resident in native system community, the total degree that above-mentioned non-essential different system cell switches occurred in 24 hours.Then base station judges whether to meet condition that is default, strangeer system adjacent cell Survey control parameter according to above-mentioned total degree again, if meet, then upgrades different system adjacent cell Survey control parameter; Wherein, the different system adjacent cell Survey control parameter cell merge condition that meet different system more more difficult than the different system adjacent cell Survey control parameter issued before through upgrading.That is, if the total degree that base station switches according to non-essential different system cell knows the coverage and service efficiency that have impact on native system community, the possibility then by the mode adjusting different system adjacent cell Survey control parameter, mobile terminal being switched in the process of carrying out cell merge to different system cell reduces, the different system adjacent cell Survey control parameter after upgrading specifically is made more more difficultly than the different system adjacent cell Survey control parameter issued before to meet cell merge condition, to reduce the probability switched to different system cell, increase the probability of resident native system community.
After base station has upgraded different system adjacent cell Survey control parameter, send to mobile terminal when needs.Mobile terminal receives the different system adjacent cell Survey control parameter through upgrading.Owing to through according to this different system adjacent cell Survey control parameter renewal, the different system cell of part is not easy to meet switching condition, so just, extend the acquisition time of Target cell, this process may have homologous ray adjacent area (comprising homogeneous-frequency adjacent-domain or alien frequencies adjacent area) to meet switching condition, such mobile terminal has just been switched on homologous ray adjacent area, still reside in native system community, efficiently avoid non-essential different system cell to a certain extent and switch.
Update condition described in the embodiment of the present invention comprises any one or its combination in following condition: the ratio of the total degree that described non-essential different system cell switches and the total degree that different system cell switches is greater than the 4th threshold value; And the total degree that described non-essential different system cell switches is greater than the 5th threshold value.Above-mentioned each condition can carry out choosing and combining according to the actual requirements.
In said method embodiment, the homologous ray nearby region measurement controling parameters of the newly-increased measurement ID that base station issues to mobile terminal both together can be handed down to mobile terminal with different system adjacent cell Survey control parameter, also can send to mobile terminal separately.
Fig. 3 is the schematic flow sheet that the present invention reduces another embodiment of method that unnecessary different system cell switches, and as shown in Figure 3, the method is still for homogeneous-frequency adjacent-domain, and the method comprises the steps:
The base station (eNB) of step 300, LTE system is for the UE sending measuring control message triggering A2 event report, homogeneous-frequency adjacent-domain Survey control parameter in this Survey control message under configuration newly-increased measurement ID, described homogeneous-frequency adjacent-domain Survey control parameter comprises one or combination in following parameter: the cell offset amount CIO in the triggered time TTT of shortening, the A3 event report of increase; Also just say it is that TTT configuration can reduce by the new homogeneous-frequency adjacent-domain Survey control parameter configured, increase A3CIO simultaneously, thus allow UE more easily report LTE homogeneous-frequency adjacent-domain, but the judgement of the intra-system handover of UE was still adjudicated according to former homogeneous-frequency adjacent-domain Survey control parameter;
Also comprise different system adjacent cell Survey control parameter in Survey control message, specifically comprise the measurement clearance (GAP) measuring different system cell, the frequency point information measuring frequency and different system adjacent cell, also comprise the information such as the threshold value meeting different system cell switching condition.
Step 301, UE reporting measurement reports, by UE reporting measurement reports, gather to eNB statistical report situation, if the measurement report that now UE reports has LTE community, and this time tangential different system cell of UE (such as UMTS community) success, then eNB counts non-essential different system cell switching times 1 time; The total degree that the non-essential different system cell that eNB statistics meets this condition in predetermined period switches;
After step 302, predetermined period terminate, if the success rate that in predetermined period, different system cell switches reaches baseline requirement and such as reaches the first threshold value, and the total degree that different system cell switches reaches certain thresholding such as reaches the second threshold value, and the ratio of the total degree of different system cell switching and the total degree of intra-system handover reaches certain thresholding such as the 3rd threshold value, then proceed step 303;
It will be understood by those skilled in the art that, each condition in this step is the operation in order to carry out increasing the difficulty switched to different system cell under more reasonably condition, to more be conducive to handover success and the business service of mobile terminal like this, but it is not necessary condition.The ratio of the total degree that step 303, the total degree calculating non-essential different system cell switching and different system cell switch, if ratio is greater than certain thresholding such as the 4th threshold value, then increasing one or more step-length by being biased Hysteresis with this amplitude switched in B1 and/or the B2 event report of corresponding QCI, increasing the difficulty switched to different system cell.
B1 and B2 is different systematic evaluation measurement of correlation, trigger condition and implication as follows:
| Measurement event | The implication represented during triggering | Scene |
| B1 | RAT adjacent area is higher than thresholding | Trigger high priority RA T to switch |
| B2 | RAT adjacent area higher than thresholding and Serving cell lower than thresholding | Trigger low priority RA T to switch |
Such as, before adjusting B1, the threshold value that different system cell switches is-100dB, and after adjustment, the threshold value that different system cell switches is-95dB, and handoff threshold value raises, and difficulty strengthens, switching delay.When finding that there is other homogeneous-frequency adjacent-domains in native system and can providing the business service meeting quality, selection resides in native system community, this avoid unnecessary different system cell to switch, in other homogeneous-frequency adjacent-domains making UE be switched to LTE system or alien frequencies adjacent area.
After eNB adjusts B1, observe the success rate that different system cell switches, if handover success rate declines, then carry out parameters back, the different system adjacent cell Survey control parameter issued before becoming by different system adjacent cell Survey control Parameter reconstruction.
The inventive method embodiment goes in the switching flow of different system community, and be preferably applicable to advanced network system in the different systematic evaluation flow process of low level network system, such as LTE system is in the cell merge flow process of UMTS/GSM etc.Wherein, the process switched to different system cell by current area, owing to can implement according to existing procedure, does not therefore too much repeat the introduction of this part in the embodiment of the present invention.
The method that the unnecessary different system cell of the minimizing that the embodiment of the present invention provides switches, judge whether that there is unnecessary different system cell switches by adjacent area coverage strength information in the switching condition gathering system of reduction homologous ray adjacent cell, the switching of unnecessary different system cell is reduced again by increasing different system cell switching condition, to increase the coverage of current system community, ensure higher QoS, and simple and practical.
