Abstract
The invention provides a method for paging a user terminal used for a radio communications system. The method comprises the following steps: a dynamic database used for saving the update information of the location of the user terminal in a certain period of time is arranged in a radio network controller; when a CN (Core Network) starts paging in a paging location area in the wireless network controller, the paging message is started at the same time at all location updating cells with histories; and if the terminal is not found, the CN stars paging all the cells in the whole paging location area of the radio network controller. When paging the user terminal, the method firstly paging the location updating cells in a certain period of time, thus effectively saving the paging bandwidth.
Description
Technical field
The invention belongs to wireless communication field, relate in particular to and be used for wireless communication system is realized paging to user terminal method.
Background technology
In wireless communication system, always having some UE (user terminal) to be in does not both have up transmitting business not have the descending professional idle condition that receives yet.When with network that the base station is associated on when having at certain idle UE professional, such as there being the voice service request of initiating to UE, the base station often needs the mode by paging, the UE that notice is in idle condition starts and prepares to receive corresponding voice service.
Wireless communication system is divided into different paging lane place with base stations different in the coverage, and dozens of even hundreds of sub-districts may be contained in a paging lane place, and the part base station can belong to two different paging lane place.
The paging lane place mainly contains following function:
1, in this zone, CN (Core Network, core net) initiates the calling to UE, and paging all can be carried out in all base stations in this zone;
2, when UE enters the service range of a new paging lane place, must initiate position updating request, be updated in the position record in the wireless communication system.
In the position is upgraded, at first, when the UE of free time (promptly, do not have between this UE and the current C N to connect) when moving into a sub-district of the paging lane place that belongs to new, UE notifies its whereabouts by sending the message that is referred to as the position renewal first, must send feasible HLR (the Home Location Register that is used for the UE maintenance of this location update message, attaching position register) and VLR (Visitor Location Register, VLR Visitor Location Register) have suitable current information about this UE and its whereabouts; Then, at CN and UE need connect or during swap data, CN paging UE in last paging lane place of UE notice then, UE replys this paging by sending a call message to CN from the sub-district at its current place.
When UE when being idle (for example, do not participate in lasting calling), can use above-mentioned location updating method, and, when UE is the free time, the position is upgraded and not only be may be used in the circuit-switched service (it can comprise voice service and or data service), and may be used in the packet switching service equally.
When paging is initiated in the CS of CN (circuit switching) territory, CN be to UE all RNC (the Radio Network Controller in the resident paging lane place, radio network controller) sends beep-page message, after RNC receives beep-page message, can in paging channel, send a class beep-page message to all sub-districts of inside, whole paging lane place, after UE receives this beep-page message, judge the response paging according to the state of self.
If paging is initiated in the CS territory of WCDMA system, CN obtains the area code of UE present located paging lane place earlier from VLR after, then by all Node Bs (the Node Base Station of RNC in this paging lane place LA (Location Area), the base station) sends call signaling, after Node B receives call signaling, send paging request message by wireless channel, UE is after receiving paging request message, send page-response message, RNC is transmitted to CN with page-response message, finishes once successful radio call.
If RNC is after sending beep-page message, in the time of default, in 4 seconds, do not receive page-response message, RNC then can send one time beep-page message again, if still do not receive page-response message in 4 seconds, the then failure of radio call this time.
By as seen above-mentioned, system is when carrying out paging to UE, the scope of paging is determined by the paging lane place, the paging lane place is big more, the Node B that covers is just many more, if the Node B number of a paging lane place covering is too much, then the user terminal number is too much, and a large amount of pagings will cause the beep-page message flow of Node B excessive, and make system loading excessive, thereby influence the problem of system's call completion ratio, if it is too small that the paging lane place is provided with, the paging lane place number of network is too much, can cause the frequent position of user terminal to upgrade, waste corresponding signal resource, the uplink load of network increases.Therefore, the method for processing beep-page message is difficult to solve paging load overload and frequent this a pair of contradiction of position renewal in the prior art.
Summary of the invention
The objective of the invention is to propose a kind of method that is used for wireless communication system to user terminal realization paging, be used for solving the paging load overload and the frequent contradiction of position renewal that prior art exists.
In order to realize the foregoing invention purpose, the present invention specifically is achieved in that
A kind of method that is used for wireless communication system to user terminal realization paging: user terminal carries out the position to be upgraded, after radio network controller is received beep-page message, whether the cell history information of judging the user terminal of collecting within a certain period of time has location update message, if have, then the sub-district is upgraded in the position that has historical record and initiate paging, otherwise, do not have, then paging is initiated in all sub-districts in the paging lane place to described user terminal place.
In the method for described realization paging, the cell history information of user terminal in the described certain hour is saved in the dynamic data base that the Wi-Fi controller is provided with;
User terminal should upgrade the cell history information of user terminal in the described database when carrying out the position renewal.
In the method for described realization paging, if the cell history information of not preserving user terminal in the described radio network controller then starts paging to this radio network controller all sub-districts in the paging lane place.
In the method for described realization paging, the Wi-Fi controller is not received replying of user terminal after paging is initiated in this sub-district, user terminal place, and then paging is initiated in Wi-Fi controller all sub-districts in the paging lane place.
Adopt method of the present invention, when user terminal is realized paging, earlier the sub-district is upgraded in position in the certain hour and carry out paging, saved the paging bandwidth effectively, therefore, not only can reduce the beep-page message flow and can alleviate the load of each base station controller, reduce message congestion, and improve the called paging call completing rate with this.
