In gsm system, because the restriction of paging channel capacity can not be put in order off the net to the beep-page message of UE, has introduced the notion of lane place thus, comprising several sub-districts in the lane place, is to realize by the paging to all sub-districts in the district of UE position to the ICQ of UE.The lane place is the least unit of renewal of UE position and ICQ, with the different lane place of LAC (Location Area Code, Location Area Code) sign, and sends in the system message of LAC on each sub-district BCCH channel.
As UE start, insertion SIM (Subscriber Identity Module, when subscriber identification module) blocking, can notify the lane place at its current place to network by IMSI (International Mobile Subscriber Identifier, IMSI International Mobile Subscriber Identity) attaching process.Along with moving of UE, in the time of in entering a new lane place, also can initiate the position and upgrade, notify new LAC to network.In addition, in order to keep the close ties between UE and the network, allow network in time grasp the positional information of UE, network requirement UE initiates periodic position to network at set intervals and upgrades; The current LAC of storage user terminal when network can upgrade in each position is as the positional information of this UE of paging.When the UE in the lane place is made a call, MSC Server (Mobile Switching Center Server, Mobile Switching Center Server) will pass through BSC (Base Station Controller, base station controller) the paging request is sent in all sub-districts in the correspondence position district, promptly can carry out paging to all UE in the lane place at this UE place.
The embodiment of the invention provides a kind of method of system for notifying user terminal of inter information of adjacent cells, as shown in Figure 1, comprises the steps:
The ability information of S101, reception UE judges according to ability information whether UE possesses different system access capability;
By being provided with at network side, UE is started shooting in the GSM sub-district and after the position upgrades, initiatively report the ability information of this terminal to BSC, whether the concrete finger of ability information possesses different system access capability.
S102, when judged result when being, send the different system information of adjacent cells of storage to UE, otherwise do not send this different system information of adjacent cells to UE;
Wherein, different system information of adjacent cells comprises the corresponding relation of the adjacent sub-district in each sub-district and different system in the district of UE present position, and the configuration information of the adjacent sub-district of different system; And different system information of adjacent cells is by non-broadcast channel, and for example dedicated channel or shared channel send to UE's.
So far, the dual-mode terminal that possesses different system access capability can normally be carried out sub-district gravity treatment and switching between different system according to different system information of adjacent cells, and do not possess the GSM terminal of different system access capability, owing to can not receive different system information of adjacent cells, so can not produce deadlock, anomaly such as restart yet.Adopt this method, promptly efficiently solve current mechanism lower network side when broadcasting different system information of adjacent cells, the problem of anomalies such as crashing, restart appears in certain customers' terminal, has effectively promoted user's impression.
The method of the system for notifying user terminal of inter information of adjacent cells that the embodiment of the invention provides, need not existing a large amount of GSM terminal to be transformed in end side, to the transformation of dual-mode terminal mainly is to make dual-mode terminal can discern and store the different system information of adjacent cells that receives from dedicated channel or shared channel, and carries out interoperability flow processs such as sub-district gravity treatment, switching according to this information.
The scheme that the embodiment of the invention provides mainly relies on network side to realize, a kind of network equipment at network side realization said method as shown in Figure 2, comprising:
