A kind of method that is in the colony terminal switching that receives service condition, this method may further comprise the steps,
Colony terminal detects from the signal strength signal intensity of source cell base station with from the signal strength signal intensity of target cell base station, judge whether to satisfy handover triggering condition, if satisfy handover triggering condition, judge then whether Target cell supports the cluster group that this colony terminal belongs to, if support, the forward shared channel information of this cluster group of intercept target Cell Broadcast CB then, directly switch to the forward shared channel of this cluster group of Target cell from the forward shared channel of cell-of-origin, if do not satisfy handover triggering condition or do not support that then colony terminal stops to switch.
Wherein, described signal strength signal intensity is a pilot signal strength, the described step that satisfies handover triggering condition that judges whether comprises, judge whether pilot signal from target cell base station is better than the pilot signal from source cell base station, and whether the result who compares reaches a threshold value.
Describedly judge whether Target cell supports the step of the cluster group that colony terminal belongs to comprise, the cluster group group number of colony terminal intercept target Cell Broadcast CB judges that the cluster group number of the cluster group whether the cluster group group number listen to is belonged to this colony terminal is consistent.
For terminal switching method in the prior art digital cellular network communication system, the present invention is according to the characteristics of group service, allow and be in the colony terminal that receives service condition according to triggering switching from the signal strength signal intensity of source cell base station with from the signal strength signal intensity of target cell base station, and the forward shared channel information of the cluster group that colony terminal belonged to by the intercept target Cell Broadcast CB, directly switch to the forward shared channel of this cluster group of Target cell from the forward shared channel of cell-of-origin, in whole handoff procedure, need not the mutual of signaling between network equipment, and need not the base station and rebulid radio traffic channel, save the Radio Resource of system, simplified the colony terminal handoff procedure that is in the reception service condition.
Description of drawings
Fig. 1 is in the prior art, is receiving the process that switches to Target cell under the professional state from the cell-of-origin when digital cellular network communication system terminal moves.
Fig. 2 shows the present invention and is in the colony terminal that receives service condition switches to Target cell from the cell-of-origin process.
Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below by specific embodiment with reference to accompanying drawing, the present invention is described in more detail.
The colony terminal of authority or VGCS business or the VBS business that the dispatcher initiates this cluster group are arranged in certain cluster group, base station system in the group calling scope is according to mobile switching centre (MSC) or Visited Location Registor (VLR) or Group Call Register (GCR, Group Call Register) the signatory service area information of this cluster group is set up forward shared channel in, and broadcast the group number of current group calling and the forward shared channel information of this cluster group by paging channel, wherein forward shared channel information comprises the frequency range of forward shared channel, demodulation parameter etc.Under the same sub-district of base station covering, may exist a plurality of cluster groups to carry out group calling simultaneously, the base station is set up forward shared channel respectively for each the cluster group under this sub-district, and the information of the forward shared channel of each cluster group is all broadcasted by paging channel.
As shown in Figure 2, Fig. 2 shows the present invention and is in the colony terminal that receives service condition switches to Target cell from the cell-of-origin process.When colony terminal is moved from target approach sub-district, cell-of-origin, colony terminal detects from the pilot signal strength A of cell-of-origin less than from a certain threshold value of pilot signal strength B of Target cell the time, colony terminal passes through the intercept target cell base station in the group number of the current group calling of paging channel broadcasting and the forward shared channel information of this cluster group, if the cluster group group number of Target cell broadcasting is consistent with the cluster group number of the cluster group that this colony terminal is belonged to, then obtain the forward shared channel information of this cluster group of Target cell, directly switch to the forward shared channel of Target cell from the forward shared channel of cell-of-origin.Above-mentioned cell-of-origin and Target cell can belong to same BSC, also can belong to the different B SC under the same MSC, also can belong to different MSC, when belonging to different B SC or different MSC, switch the forward shared channel that does not need MSC or BSC to participate in and directly switch to Target cell from the forward shared channel of cell-of-origin.
Because colony terminal all is to share radio traffic channel in each Serving cell, be not at the independent assignment of certain colony terminal, when some colony terminal in the cluster group switch the cell-of-origin after, forward shared channel originally still can not be removed, may also have other colony terminals using this shared channel this moment, equally, existing this cluster group forward shared channel in the Target cell, need not newly-built radio traffic channel, can be directly switch to existing wireless sharing channel continuation business in the Target cell, be that MSC or BSC participate in so do not need network side in the process of switching.Certainly, if Target cell is not supported the group service of this cluster group, that is, the cluster group number of the cluster group that is belonged to when the cluster group group number of colony terminal intercept target Cell Broadcast CB and this colony terminal is inconsistent, and colony terminal will not switch.
In group service, no matter be the VGCS business, or VBS business, all have the characteristics that a plurality of colony terminals of cluster group receive promoter's group calling simultaneously, these are in the colony terminal that receives service condition when the cell-of-origin switches to Target cell, use method provided by the present invention, not only need not the participation of network side during switching, and target cell base station need not to have saved the Radio Resource of system for colony terminal rebulids radio traffic channel, improved the speed of switching.
