Embodiment
For making the object, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Main thought of the present invention is: between base station controller (BSC) and radio network controller (RNC), increase a cell reselection notification message.Message direction is from BSC to RNC.This message is used for the identification information of UE, GSM cell identity information, Target Cell Identifier information band to RNC.UE, after RNC side finishing service is set up, in the time of can or processing different system cycle measurement report when issuing isosystem measurement control, increases interim punishment biasing to corresponding GSM adjacent area, makes to adjudicate the possibility reduction that UE reselects to GaiGSM community.
Fig. 1 is the schematic flow sheet of the embodiment of the present invention one, and as shown in Figure 1, this embodiment mainly comprises:
Wherein, described BSC is the BSC of described UE under before described gravity treatment, described cell reselection notification message carry described UE before described gravity treatment under the identification information, the identification information of Target cell and the identification information of described UE of gravity treatment of GSM community.The identification information of concrete UE can be international mobile subscriber identity (IMSI) information.
Here it should be noted that, the present invention is particularly useful for the cell reselection situation of connected state UE.
In actual applications, in subsequent process, Target RNC has the corresponding adjacent area of the relevant information DuiGSM community that cell reselection notification message that sufficient time utilization receives carries independently to setover and punish, be the better opportunity that sends described cell reselection notification message: at described BSC, to described UE, send cell reselection instruction (cell change order) before.
Here, described cell reselection notification message can transmit by the IUR-G interface between BSC and RNC.
The described information that step 102, described Target RNC carry the described cell reselection message receiving and the corresponding relation between described information, be recorded in the 2G-3G system gravity treatment contingency table of self preserving.
Here, the described information that cell reselection message is carried and the corresponding relation between described information are as a record, be recorded in the 2G-3G system gravity treatment contingency table of RNC preservation, to inquire about the identification information of the Target cell of corresponding gravity treatment according to the sign of UE in step 103.
Here, when the Target cell that Target RNC inquires consistent with the community of the current access of described UE, illustrate that UE is before from current area gravity treatment to described GSM community, then again from this GSM cell reselection to current area, now, for fear of ping-pong reselection occurs, need corresponding the punishing for carrying out the parameter (independently setovering in adjacent area) of cell reselection judgement in Dui Gai GSM community, the difficulty that reselects to GaiGSM community to improve UE, concrete method is:
When issuing different system event measurement control or when processing different system cycle measurement report, according to Qoffset2=Qoffset1+QoffsetModify, determine that adjacent area corresponding to described GSM community is independently biased to Qoffset2.
Wherein, the GSM adjacent area that described Qoffset1 configures while the being normal isosystem measurement standard value of independently setovering, its method to set up is identical with the method to set up in existing system, does not repeat them here.
Described QoffsetModify is that default cell reselection is punished biasing temporarily, and this value is greater than 0.As QoffsetModify hour, punishment dynamics is little, and UE gravity treatment is little to the difficulty of this GSM network, otherwise, when QoffsetModify is large, punishment great efforts, UE gravity treatment is large to the difficulty of this GSM network.In actual applications, those skilled in the art arrange suitable value to QoffsetModify according to actual needs.
Further, determine that adjacent area corresponding to described GSM community can also delete recorded information corresponding to UE described in described 2G-3G system gravity treatment contingency table after independently setovering, so that upper when once issuing isosystem measurement and controlling, do not need adjacent area corresponding to Zai Dui GSM community independently to setover and punish, avoid due to adjacent area corresponding to Dui Gai GSM community repeatedly independently setover due to punishing from now on when the signal extreme difference of 3G network cannot provide service UE again gravity treatment to this GSM adjacent cell.
In actual applications, described isosystem measurement is controlled and is comprised: 3A measures and controls and 3C measurement control.The 3C of take below measures and controls is example, and the specific implementation of step 103 is described.
As shown in Figure 2, when UE completes after the business process of establishing at 3G network, UE reselects to behind RNC community, and RNC side handling process comprises the steps:
Step 201: judge whether RNC side needs to issue 3C and measure control, if needed, forwards step 202 to, otherwise finishes.
Step 202: whether judgement can find the IMSI1 of corresponding described UE in 2G-3G system gravity treatment contingency table, if can find, forwards step 203 to, otherwise forwards step 204 to.
Step 203: search the corresponding GSM of IMSI1 community GSM1, independently setovered and be defined as Qoffset2 in the adjacent area of corresponding GSM community GSM1, and fill in 3C measurement control message execution step 205, wherein, Qoffset2=Qoffset1+QoffsetModify.
Step 204: the adjacent area of determining GSM community GSM1 is independently biased to Qoffset1, and fill in 3C measurement control message.
Step 205: issue 3C and measure control message, trigger UE and independently setover according to the adjacent area of the 2G cell GSM1 of this information updating self preservation.
Step 206: delete the corresponding record of IMSI1 described in 2G-3G system gravity treatment contingency table.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
