| Downlink signal receiving quality | 6.2 | 5.6 | 4.8 | … | 2.6 | 2.2 |
Wherein, above-mentioned level value and signal receiving quality value are statistic, and are the numerical value after power control compensation.
Further, the uplink and downlink signals quality of reception is except characterizing with the form of table 1, all right HQI (High Quality Identity, high-quality identifies) characterize, wherein, the total degree * 100% of up HQI=(number of times of the number of times+upward signal quality of reception 3 of the number of times+upward signal quality of reception 2 of the number of times+upward signal quality of reception 1 of the upward signal the quality of reception 0)/upward signal quality of reception 0 ~ 7, the ratio namely shared by the upward signal quality of reception 0 ~ 3; The total degree * 100% of descending HQI=(number of times of the number of times+downlink signal receiving quality 3 of the number of times+downlink signal receiving quality 2 of the number of times+downlink signal receiving quality 1 of downlink signal receiving quality 0)/downlink signal receiving quality 0 ~ 7, the ratio namely shared by downlink signal receiving quality 0 ~ 3; If characterize the uplink and downlink signals quality of reception with HQI, then go up table 1 and can be replaced following table 2.
Table 2
| Up level value (decibel millivolt) | <-108 | -108 | -107 | … | -56 | -55 |
| Downlink electrical level values (decibel millivolt) | <-100 | -100 | -99 | … | -48 | -47 |
| Up HQI | 90％ | 92％ | 93％ | … | 99％ | 99.5％ |
| Descending HQI | 90％ | 92％ | 93％ | … | 99％ | 99.5％ |
Wherein, above-mentioned level value and up-downgoing HQI are statistic, and are the numerical value after power control compensation.
It should be noted that, the BSC of GSM community is when sending the mapping table between its uplink and downlink level value and uplink and downlink signal receiving quality value to the RNC of UMTS community, both the form of above-mentioned table 1 can have been adopted also can to adopt the form of above-mentioned table 2, and concrete which kind of form the present embodiment that adopts is not construed as limiting this.
In addition, because UMTS community and GSM community belong to different communication network, can not directly communicate, so BSC is when sending the mapping table between its uplink and downlink level value and uplink and downlink signal receiving quality value, mapping table between this uplink and downlink level value and uplink and downlink signal receiving quality value need be transmitted by centralized control network element.Wherein, all there is correspondence in the BSC of RNC and the GSM community of centralized control network element and UMTS community.BSC is when sending the mapping table between its uplink and downlink level value and uplink and downlink signal receiving quality value, first this mapping table is sent to centralized control network element, by centralized control network element, this mapping table is passed to RNC again, RNC, after obtaining this mapping table, just can continue to perform follow-up processing flow.
203:RNC obtains up level value and the uplink and downlink signal receiving quality value of each GSM community according to the downlink electrical level values of each GSM community mapping table inquired about between the uplink and downlink level value of each GSM community and uplink and downlink signal receiving quality value;
Be-99 decibels of millivolts for the downlink electrical level values of a certain GSM community got, then RNC is after the numerical value getting this descending level, just can according to the up level value of GSM community, mapping table uplink and downlink level value and uplink and downlink signal receiving quality value between of this numerical value inquiry as shown in table 1 in above-mentioned steps 202, to obtain the up level value of GSM community, uplink and downlink signal receiving quality value that uplink and downlink level value is corresponding.If signal receiving quality adopts the forms of characterization of above-mentioned table 1, then as shown in Table 1, the up level value corresponding with downlink electrical level values-99 decibels of millivolts is-107 decibels of millivolts, the upward signal reception quality value corresponding with up level value-107 decibels of millivolts is 4.8, the downlink signal receiving quality value corresponding with downlink electrical level values-99 decibels of millivolts is 4.8, thus obtains up level value and uplink and downlink signal receiving quality value according to downlink electrical level values;
In addition, if signal receiving quality adopts the forms of characterization of above-mentioned table 2, then after the numerical value getting descending level, just can according to the mapping table between the uplink and downlink level value of the GSM community of this numerical value inquiry as shown in table 2 in above-mentioned steps 202 and uplink and downlink signal receiving quality value, to obtain the up level value of GSM community, uplink and downlink signal receiving quality value that uplink and downlink level value is corresponding.As shown in Table 2, the up level value corresponding with downlink electrical level values-99 decibels of millivolts is-107 decibels of millivolts, the upward signal reception quality value corresponding with up level value-107 decibels of millivolts is 93%, the downlink signal receiving quality value corresponding with downlink electrical level values-99 decibels of millivolts is 93%, thus obtains uplink and downlink signal receiving quality value according to uplink and downlink level value;
204:RNC carries out switch decision according to the uplink and downlink level value of each GSM community and uplink and downlink signal receiving quality value;
For this step, RNC carries out switch decision according to the uplink and downlink level value of each GSM community and uplink and downlink signal receiving quality value, includes but not limited to as under type:
When the uplink and downlink level value that RNC judges arbitrary GSM community all higher than the first pre-determined threshold and uplink and downlink signal receiving quality value all lower than the second pre-determined threshold time, judge that the uplink and downlink level value of this arbitrary GSM community and uplink and downlink signal receiving quality value meet switch decision condition.
Wherein, the first pre-determined threshold specifically can be-65 decibels of millivolts, and certainly, the size of the first pre-determined threshold, except above-mentioned numerical value, also can be other numerical value, such as ,-70 or-75 decibels of millivolts, the size of the present embodiment to the first pre-determined threshold does not specifically limit; The forms of characterization of the size basis signal quality of reception of the second pre-determined threshold and determining, if signal receiving quality directly characterizes with the form of table 1 in above-mentioned steps 202, then the size of the second pre-determined threshold specifically can be 4.5, the size of certain second pre-determined threshold is except above-mentioned numerical value, also can be other numerical value, such as, 4 or 5, the size of the present embodiment to the second pre-determined threshold does not specifically limit equally; If signal receiving quality characterizes with the form of table 2 in above-mentioned steps 202, then the size of the second pre-determined threshold specifically can be 80%, the size of certain second pre-determined threshold is except above-mentioned numerical value, also can be other numerical value, such as, 85% or 90%, the size of the present embodiment to the second pre-determined threshold does not specifically limit.
205: if the uplink and downlink level value of arbitrary GSM community and uplink and downlink signal receiving quality value meet switch decision condition, then RNC issues switching command to UE, switch to this arbitrary GSM community with control UE.
Wherein, after judging that this arbitrary GSM community meets switch decision condition, just issue switching command by air interface to UE, UE, after receiving switching command, just from UMTS cell merge to this arbitrary GSM community, and then ensure that the continuity of communication.
In addition, situation when simultaneously meeting switch decision condition for the uplink and downlink level value and uplink and downlink signal receiving quality value that there is multiple GSM community, the method that the present embodiment provides also comprises: the switching cell of GSM community as UE selecting uplink and downlink level value optimum or uplink and downlink signal receiving quality value optimum or uplink and downlink level value and the equal optimum of uplink and downlink signal receiving quality value, and control UE switches to this community.Wherein, it is maximum that uplink and downlink level value optimum refers to uplink and downlink level value, and it is minimum that uplink and downlink signal receiving quality value optimum refers to uplink and downlink signal receiving quality value.Such as, if 3 GSM communities all meet switch decision condition, with symbol GSM1, GSM2 and GSM3 identifies 3 GSM communities, GSM1's is upper, downlink electrical level values is-85 decibels of millivolts and-88 decibels of millivolts, on, downlink signal receiving quality value is 4 and 5, GSM2's is upper, downlink electrical level values is-80 decibels of millivolts and-85 decibels of millivolts, on, downlink signal receiving quality value is 3 and 4, GSM3's is upper, downlink electrical level values is-75 decibels of millivolts and-80 decibels of millivolts, on, downlink signal receiving quality value is 2 and 3 is example, if and more than, downlink electrical level values is optimum as choice criteria, then select GSM3 community as the target handover cell of UE.
Below in conjunction with a concrete example, in detail explanation is explained to the switch determining method that above-mentioned steps 201 to step 205 provides.
Be in talking state so that a certain UE is current, and to be in UMTS cell edge be example, then in order to ensure the continuity of this UE, need to carry out cell merge.Suppose that the GSM community contiguous with this UMTS community has 2, identify with symbol G1 and G2 respectively, and unification is controlled by BSC1, then before carrying out switch decision, BSC1 just for each GSM community generates the mapping table between corresponding uplink and downlink level value and uplink and downlink signal receiving quality value, and deposits in self.When RNC is when carrying out switch decision, first can obtain via centralized control network element the mapping table between uplink and downlink level value and uplink and downlink signal receiving quality value being stored in 2 GSM communities in BSC1, and the downlink electrical level values of each GSM community reported according to be switched UE, mapping table between the uplink and downlink level value that inquiry is corresponding and uplink and downlink signal receiving quality value, obtains up level value and the uplink and downlink signals quality of reception of each GSM community.
Suppose that to be switched UE has reported the descending level of G1 and G2, and the downlink electrical level values of G1 is-70 decibels of millivolts, the downlink electrical level values of G2 is-80 decibels of millivolts.Afterwards, RNC inquires about the mapping table between the uplink and downlink level value of G1 and G2 and uplink and downlink signal receiving quality value respectively according to the downlink electrical level values of the two, and the up level value obtaining G1 is-82 decibels of millivolts, downlink signal receiving quality is 5, and the upward signal quality of reception is 6; The up level value of G2 community is-88 decibels of millivolts, downlink signal receiving quality is 2, up quality is 1, be-85 decibels of millivolts with the first pre-determined threshold, second pre-determined threshold is 4 is example, then because the uplink and downlink signals quality of reception of G1 does not meet pre-determined threshold, G1 therefore can not be selected as the target handover cell of to be switched UE, and select G2 as the target handover cell of to be switched UE at UMTS cell edge place.
In addition, the community at the current place of UE is except the UMTS community shown in the present embodiment, also can be LTE community, GSM community, TD-SCDMA (Time Division-Synchronous Code Division MultipleAccess, TD SDMA) community, CDMA (Code Division Multiple Access, code division multiple access) community, Wimax (Worldwide Interoperability for Microwave Access, micro-wave access global inter communication) community; The to be switched community of UE, except the GSM community shown in the present embodiment, can also be LTE community, UMTS community, TD-SCDMA community, CDMA community, Wimax community; Namely the control method of cell merge that provides of the present embodiment, both can realize the switching between different communication network, also can realize the switching between same communication network.And no matter UE is by which cell merge to another community, switch decision mode is all consistent with the switch decision mode of above-mentioned steps 201 to step 205, repeats no more herein.Such as, when UE by LTE cell merge to GSM community or by TD-SCDMA cell merge to GSM community time, the controller of LTE community or the controller of TD-SCDMA community are when carrying out switch decision, and its switch decision mode all can adopt the RNC of above-mentioned steps 201 to step 205 to carry out the mode of switch decision.
It should be noted that, the controller of the to be switched community of UE is sending on it, downlink electrical level values and upper, after mapping table between downlink signal receiving quality value to centralized control network element, this corresponding relation can not be forwarded to the controller of community, UE current place by centralized control network element, and directly according to this mapping table and on, downlink electrical level values carries out switch decision, and centralized control network element is when carrying out switch decision, the mode that its switch decision mode carries out switch decision with the RNC of above-mentioned steps 201 to step 205 is consistent, after obtaining court verdict, again court verdict is sent to the controller of community, UE current place.
The method that the present embodiment provides, after the uplink and downlink level value obtaining to be switched community and uplink and downlink signals mass value, switch decision is carried out according to uplink and downlink level value and uplink and downlink signal receiving quality value, therefore, judgement mode is more rigorous, improve the success rate of cell merge, and after the uplink and downlink level value and uplink and downlink signal receiving quality value that judge arbitrary to be switched community meet switch decision condition, issue switching command control UE and switch to this to be switched community, thus ensure that the continuity of communication.
