Embodiment
The characteristic of microcellulor network is can allow mobile terminal Cong Yuan community seamlessly switch to community, ,Qi Central Plains, Target cell and Target cell can be homogeneous-frequency adjacent-domain, can certainly be different frequency/different system adjacent area.As shown in Figure 1, mobile terminal moves to Long Term Evolution (long term evolution; Hereinafter to be referred as the LTE) edge of community A, the condition of supposing community A intra-system handover be homogeneous-frequency adjacent-domain than high 3 decibels of current area level (dB), and mobile terminal does not detect the homogeneous-frequency adjacent-domain that meets this switching condition always; By the time level drops to after certain thresholding, for what guarantee business, be normally necessary to trigger different frequency/different system measurement, mobile terminal carries out different frequency/different system nearby region measurement according to the measurement indication of base station, and different frequency/different system adjacent area covers better, mobile terminal measures the community that meets switching condition different frequency/different system very soon, and carries out community switching.
Owing to controlling parameter with the frequently measurement of switching condition in prior art, arrange unreasonablely, cause the generation of some unnecessary switchings.Various embodiments of the present invention are in order to reduce unnecessary switching, provide a solution at mobile terminal reporting for before carrying out the cell measurement results of switch decision, by issuing in advance the measurement of the homogeneous-frequency adjacent-domain of current area, control the mode of parameter, reduce the switching condition of homogeneous-frequency adjacent-domain, make more homogeneous-frequency adjacent-domain can become the alternative of Target cell, expand range of choice and optimize community switching.
Fig. 2 is the schematic flow sheet of cell switching control method embodiment of the present invention, and as shown in Figure 2, the method comprises the steps:
Step 101, receive that mobile terminal sends for showing that the signal quality of current area can not meet after the message of pre-provisioning request, to described mobile terminal, send and measure control message;
Mobile terminal resides in current area to carry out in the process of wireless traffic, mobility due to mobile terminal, it may progressively 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 can cause the signal quality of current area can not meet pre-provisioning request, need to carry out the peripheral cell to measure the mode request of the base station reporting measurement reports of ,Yi Xiang current area and carry out community switching.
Mobile terminal is known in the process that current area signal quality reduces in detection, can constantly to the homogeneous-frequency adjacent-domain of current area, carry out cell measurement, by the information reporting of homogeneous-frequency adjacent-domain of switching condition that meets homogeneous-frequency adjacent-domain to base station.The switching condition of homogeneous-frequency adjacent-domain described herein is that mobile terminal is handed down in base station before this step, and for example the switching condition of homogeneous-frequency adjacent-domain is event A3(Event A3) thresholding is 3dB, the triggered time, (Time to Trigger, TTT) was 320ms.If mobile terminal detects behind the homogeneous-frequency adjacent-domain that meets above-mentioned default switching condition, report base station, just base station can be switched to mobile terminal on this homogeneous-frequency adjacent-domain.If base station does not receive the measurement report of mobile terminal reporting, show that the periphery of current area does not have to meet the homogeneous-frequency adjacent-domain of above-mentioned switching condition, therefore in the embodiment of the present invention when receive mobile terminal transmission for showing that the signal quality of current area can not meet after the message of pre-provisioning request, just carry out immediately handover optimization, specifically to mobile terminal, send and measure control message, allow mobile terminal carry out cell measurement according to the indication of this measurement control message.
In the embodiment of the present invention, measure the measurement control parameter that control message comprises the homogeneous-frequency adjacent-domain of current area, this measurement is controlled parameter and is comprised triggered time TTT, and with frequency handoff threshold, and described measurement control parameter more easily meets community switching condition than preset measurement control parameter; Described preset measurement is controlled parameter for sending at described mobile terminal for before showing that the signal quality of current area can not meet the message of pre-provisioning request, by described mobile terminal, received, that is to say that switching condition corresponding to this measurement control parameter (also can be called: the switching condition of predetermined homogeneous-frequency adjacent-domain) more easily meet switching condition than preset switching condition corresponding to measurement control parameter.Owing to not detecting according to the switching condition of before default homogeneous-frequency adjacent-domain the homogeneous-frequency adjacent-domain satisfying condition, in order to carry out handover optimization, parameter is controlled in the measurement that issues the homogeneous-frequency adjacent-domain of the current area resetting in the embodiment of the present invention, and the measurement re-issuing control parameter more easily meets community switching condition than preset measurement control parameter, object is the detection range that increases homogeneous-frequency adjacent-domain, makes the homogeneous-frequency adjacent-domain of switching condition default before can not meeting can meet the lower switching condition resetting.Give an example, described same frequency handoff threshold can be for meeting in agreement 3GPP TS 36.331 thresholding of the measurement event of definition, such as the thresholding of A3 event etc.For instance, the switching condition of default homogeneous-frequency adjacent-domain is that A3 event thresholding is 3dB before, and TTT is 320ms, and the A3 event thresholding comprising in the measurement control message of this configuration is 2dB, and TTT is 160ms.Because switching condition has reduced, more homogeneous-frequency adjacent-domain will become the alternative of Target cell, has more been conducive to community and has switched.
Step 102, receives described mobile terminal and carries out according to described measurement control message the measurement report reporting after cell measurement, and according to described measurement report, described mobile terminal is carried out to community switching controls.
Base station is after mobile terminal sending measuring control message, and mobile terminal is controlled parameter by the measurement of the homogeneous-frequency adjacent-domain of basis current area wherein and continued homogeneous-frequency adjacent-domain to carry out cell measurement, obtains measurement report, and this measurement report is reported to base station.Base station is after receiving this measurement report, just can to this mobile terminal, carry out according to the content of measurement report the control of community switching, be mobile terminal and select applicable community as Target cell, and control mobile terminal and be switched on this Target cell, complete community and switch.
The cell switching control method that the embodiment of the present invention provides, before mobile terminal reporting is used for carrying out the cell measurement results of switch decision, the mode of parameter is controlled in the measurement that issues in advance the homogeneous-frequency adjacent-domain of current area, reduce the switching condition of homogeneous-frequency adjacent-domain, make more homogeneous-frequency adjacent-domain can become the alternative of Target cell, expand range of choice and optimize community switching, reduced unnecessary but changing.
In the above-described embodiments, when mobile terminal can't detect behind the homogeneous-frequency adjacent-domain satisfying condition according to the switching condition of default before homogeneous-frequency adjacent-domain, can trigger different frequency/different system measurement, base station will send the measurement control parameter of different frequency/different system adjacent area to mobile terminal, mobile terminal controls according to the measurement of this different frequency/different system adjacent area the cell measurement that parameter is carried out different frequency/different system.The measurement of the homogeneous-frequency adjacent-domain of the current area that therefore in said method embodiment, base station issues to mobile terminal is controlled parameter and both can be sent to separately mobile terminal, also can preferably control parameter with the measurement of different frequency/different system adjacent area and together be handed down to mobile terminal, be that base station sends to the measurement of the homogeneous-frequency adjacent-domain that had both comprised current area in the measurement control message of mobile terminal to control parameter, also comprise that parameter is controlled in the measurement of different frequency/different system adjacent area.Accordingly, mobile terminal receives after this measurement control message, when carrying out cell measurement, should measure homogeneous-frequency adjacent-domain, again different frequency/different system adjacent area is measured.Particularly, parameter is controlled in the measurement of different frequency/different system adjacent area can comprise that measurement clearance (GAP), the measurement frequency of measuring different frequency/different system adjacent area are the frequency point information of different frequency/different system adjacent area, also comprises the threshold value that meets different frequency/different system switching condition.
The step that said method embodiment Zhong, base station is carried out community switching controls according to the measurement report of mobile terminal to this mobile terminal specifically can comprise following several situation:
The first situation: Jin You homogeneous-frequency adjacent-domain satisfies condition, particularly: if only comprise the cell measurement information of Yi Ge homogeneous-frequency adjacent-domain in measurement report, mobile terminal is switched to this homogeneous-frequency adjacent-domain; If measurement report comprises the cell measurement information of a plurality of homogeneous-frequency adjacent-domains, mobile terminal is switched to the best homogeneous-frequency adjacent-domain of signal quality.
The second situation: only have different frequency/different system adjacent area to satisfy condition, particularly: if only comprise the cell measurement information of a different frequency/different system adjacent area in measurement report, mobile terminal is switched to this different frequency/different system adjacent area; If measurement report comprises the cell measurement information of a plurality of different frequency/different systems adjacent area, mobile terminal is switched to the best different frequency/different system adjacent area of signal quality.
The third situation: existing homogeneous-frequency adjacent-domain satisfies condition, there is again different frequency/different system adjacent area to satisfy condition, particularly: if both comprised the cell measurement information of homogeneous-frequency adjacent-domain in measurement report, the cell measurement information that also comprises different frequency/different system adjacent area, according to preset rules, for mobile terminal is selected the Target cell of switching for community.Described preset rules can, for using the best homogeneous-frequency adjacent-domain of signal quality as Target cell, preferentially select homogeneous-frequency adjacent-domain as alternative; Or, can also Wei Jiang homogeneous-frequency adjacent-domain and different frequency/different system adjacent area in signal quality best as Target cell, be about to all adjacent areas that can meet switching condition all as alternative.

Step 201,Xiang base station sends for showing that the signal quality of current area can not meet after the message of pre-provisioning request, receives the measurement control message that described base station sends;
In embodiment of the method as shown in Figure 2, mobile terminal detection knows that the signal quality of current area can not meet reservation and require Hou,Xiang base station to send a notification message.Base station is to mobile terminal sending measuring control message, and parameter is controlled in this measurement of measuring in control message homogeneous-frequency adjacent-domain that can current area, also can comprise that parameter is controlled in the measurement of different frequency/different system adjacent area.As mentioned above, the measurement control parameter that parameter and different frequency/different system adjacent area are controlled in the measurement of homogeneous-frequency adjacent-domain can issue separately, also can be included in the lump to measure in control message to issue.Described measurement is controlled parameter and is more easily met community switching condition than preset measurement control parameter, described preset measurement is controlled parameter for sending at described mobile terminal for before showing that the signal quality of current area can not meet the message of pre-provisioning request, by described mobile terminal, received, make more homogeneous-frequency adjacent-domain more easily meet switching condition.Parameter is controlled in the measurement of homogeneous-frequency adjacent-domain can comprise measurement triggering time T TT and same handoff threshold frequently.
Step 202, carries out cell measurement according to described measurement control message, and the measurement report of cell measurement is reported to described base station;
Mobile terminal carries out cell measurement according to measuring control message, measures the measurement of the homogeneous-frequency adjacent-domain that only comprises current area in control message control parameter if specifically comprise, mobile terminal only carries out the measurement of homogeneous-frequency adjacent-domain; If both comprised the measurement of the homogeneous-frequency adjacent-domain of current area in measurement control message, controlled parameter, parameter is controlled in the measurement that also comprises different frequency/different system adjacent area, mobile terminal should be measured homogeneous-frequency adjacent-domain when carrying out cell measurement, again different frequency/different system adjacent area is measured.Particularly, parameter is controlled in the measurement of different frequency/different system adjacent area can comprise that measurement clearance (GAP), the measurement frequency of measuring different frequency/different system adjacent area are the frequency point information of different frequency/different system adjacent area, also comprises the threshold value that meets different frequency/different system switching condition.

Step 301, mobile terminal UE are to base station eNB reporting measurement event, and this event shows that the signal quality of current area does not meet predetermined requirement;
The signal quality of mobile terminal UE detection current area knows that can not meet pre-provisioning request Hou,Xiang base station sends a notification message.Inventing the base station relating in each example can be the eNB(evolved NodeB in LTE), or universal mobile telecommunications system (universal mobile telecommunications service; Be called for short: (the radio node controller of the radio network controller UMTS); Be called for short: RNC), or global system for mobile communications (global system for mobile; Be called for short: (the base station controller of the base station controller GSM); Be called for short: BSC) etc.
The measurement event that UE reports, can be the Reference Signal Received Power (RSRP, reference signal received power) in LTE, (the received signal code power of the received signal code power in UMTS; Be called for short: RSCP), the receiving level strength in GSM (Rxlev, received signal level); Also can be signal quality, as the Reference Signal Received Quality (RSRQ in LTE, reference signal received quality), signal to noise ratio (Ec/N0 in UMTS, Ratio of energy per modulating bit to the noise spectral density), incoming level quality in GSM (RxQual, received signal quality).The judgement cell signal quality of mentioning in the embodiment of the present invention, can characterize by above-mentioned each parameter, or parameter that also can reflected signal quality by other characterizes.
Described pre-provisioning request can be configured by signaling message in advance by the current serving BS of UE.

The different measuring report reporting according to UE, eNB can correspondingly carry out switch decision:
Case1: if UE only reports the cell measurement information of Liao Yige homogeneous-frequency adjacent-domain, carry out with frequently switching as switching target small area ZeeNBJiang Gai homogeneous-frequency adjacent-domain; If UE has reported the cell measurement information of a plurality of homogeneous-frequency adjacent-domains, eNB can select RSRP or the best community of RSRQ to carry out with frequently switching as switching target small area.
Case2: if UE has reported the cell measurement information of homogeneous-frequency adjacent-domain and the cell measurement information of alien frequencies adjacent area simultaneously, or the cell measurement information of the cell measurement information of homogeneous-frequency adjacent-domain and different system adjacent area, in the measurement report that eNB reports according to UE, whether the signal quality of the signal quality of homogeneous-frequency adjacent-domain and different frequency/different system adjacent area is adjudicated and is carried out with frequently switching, or carries out the different system switching of alien frequencies.For example, if the signal receiving strength of alien frequencies or different system adjacent area or signal receiving quality are than the high 3dB that surpasses of the threshold value of setting, illustrate that the signal quality of alien frequencies or different system is fine, still carry out alien frequencies or different system and switch.
Case3: if UE has only reported the cell measurement information of an alien frequencies or different system adjacent area, eNB initiates to switch to this alien frequencies or different system adjacent area; If UE has reported the cell measurement information of a plurality of alien frequencies or different system adjacent area, eNB can select the signal receiving strength of alien frequencies or different system adjacent area or the best community of signal receiving quality to carry out alien frequencies or the switching of different system as switching target small area.
