Specific embodiment
As shown in figure 1, residence reselecting first embodiment includes in group system of the present invention：
S1：Base station sends the first reselecting parameters and the second reselecting parameters to user equipment.
Base station connects core net and carries out radio communication with user equipment, provides communication overlay for corresponding geographic area.
Base station can be macro base station, micro- (micro) base station or slight (pico) base station.In certain embodiments, base station can also be claimed
For wireless base station, access point, B node, evolved B node (eNodeB, eNB) or other suitable terms.
User equipment can be it is fixed can also be it is mobile, can be transmitter receiver, radio station, cell phone etc..
Base station can be set to the user for being in wireless heterogeneous networks Idle state and have group service using cluster specific messages
Preparation send the first reselecting parameters, sends second reselecting parameters to all user equipmenies with broadcast mode.Cluster specific messages are referred to
The message that the user equipment for having group service can just be received.In this case, the user equipment without group service will not connect
Group's dedicated system message is collected, is easy to differentiation to send reselecting parameters.Certainly, base station can also be with broadcast mode to all users
Equipment sends the first reselecting parameters and the second reselecting parameters.
First reselecting parameters are different from the second reselecting parameters.First reselecting parameters are applied in RRC Idle state and have collection
Cell reselection under group business state, the second reselecting parameters are applied under RRC Idle state and no group service state
Cell reselection.
Measurement thresholding in first reselecting parameters and the second reselecting parameters can be with difference, when the Serving cell that UE measurements are obtained
Signal quality less than measurement thresholding when, by start measurement, signal quality typically use Reference Signal Received Power (Reference
Signal Receiving Power, RSRP) represent.In general the measurement thresholding in the first reselecting parameters is higher than the second gravity treatment
The measurement thresholding of parameter.So that in the case of serving cell signal quality difference, in RRC Idle state and there is the user of group service
Equipment is with easier starting up measurement in RRC Idle state and compared with not having the user equipment of group service.
Handoff threshold in first reselecting parameters and the second reselecting parameters can be with difference.When the Target cell that UE measurements are obtained
The signal quality of (typically adjacent with Serving cell) is better than Serving cell, and both differences are more than or during handoff threshold, will weight
Select to Target cell.In general the handoff threshold in the first reselecting parameters is made less than the handoff threshold in the second reselecting parameters
RRC Idle state must be in and had the user equipment of group service and be in RRC Idle state and there is no the user equipment of group service
Compare easily gravity treatment.
S2：In RRC Idle state and the user equipment that has group service is measured using the first reselecting parameters and cell
Gravity treatment, in RRC Idle state and the user equipment that do not have group service is measured using the second reselecting parameters and cell reselection.
Whether user equipment can be had group service, joined using corresponding gravity treatment according to the group service state of itself
Number is measured and cell reselection.
Illustrate with reference to accompanying drawing, as shown in Fig. 2 cell Cell1 and cell Cell2 have overlapping coverage areas, RRC Idle state
And UE1 the and RRC Idle state and the UE2 that do not have group service for having group service is respectively positioned on the overlapping coverage areas and wireless environment
Identical, the signal quality of the Cell2 shown in figure is substantially better than Cell1.UE1 and UE2 resides in Cell1 originally, by making
With different reselecting parameters, UE1 reselects to Cell2 to ensure group service quality, and UE2 still resides in Cell1.
By the enforcement of above-described embodiment, differentiation RRC Idle state and there are the user equipment and RRC of group service idle
The state and user equipment for not having group service measures the reselecting parameters used with cell reselection, can cause RRC Idle state
And the user equipment for having group service is while reside in the more preferable cell of signal quality and ensure group service quality, nothing is not affected
The user equipment of group service, it is to avoid unnecessary power wastage.
As shown in figure 3, residence reselecting second embodiment in group system of the present invention, is in group system of the present invention
