Abstract
The invention advances a method for calling user terminal in wireless communications system; with the method, calls are classified according to the mobility of UE; the system starts calling all communities in the position area for calling the mobile UE, and the system starts calling in the community in which the UE is located first for calling static UE and then calls all communities in the position area if the UE could not be called. By adopting the method, calling information flow volume could be reduced to decrease the load of every base station controller and the blockage of information is deduced to promote the call completion rate; at the same time, a large amount of call channel resource could be saved, especially for most users in prosperous downtown or office buildings who are static with limited wireless resources, the effect is obvious.
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 in 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 in the 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 LocationRegister, 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 overcoming 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 wireless communication system that is used for realizes that to user terminal the method for paging comprises, user terminal is conversed or the position is upgraded, after the Wi-Fi controller is received beep-page message, judge that according to the cell history information of user terminal in the certain hour of preserving user terminal remains static or mobile status, if user terminal is in mobile status, then the Wi-Fi controller starts the paging to all sub-districts in the paging lane place; If user terminal remains static, then the Wi-Fi controller is initiated paging to this sub-district, user terminal place.
In the method for realization paging of the present invention: the cell history information of user terminal in the described certain hour is saved in the dynamic data base of Wi-Fi controller setting; User terminal should upgrade the cell history information of user terminal in the described database conversing or position when upgrading.
In the method for realization paging of the present invention, described cell history information according to user terminal in the certain hour of preserving judges that user terminal remains static or mobile status, specifically be meant: according to the cell history recording of information, judge user terminal carry out several times conversations or position when upgrading whether all in the sub-district of same base station administration, if, then user terminal remains static, otherwise user terminal is in mobile status.
In the method for realization paging of the present invention, described 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, the beep-page message flow can be reduced and the load of each base station controller can be alleviated with this, reduce message congestion, improve the called paging call completing rate, and save paging channel resource in a large number, particularly be in inactive state in bustling commercial center or the most of user in office building the inside, and the Radio Resource anxiety, reduction effect is obvious.

S104, if UE is in mobile status, then RNC starts the paging to all sub-districts in the paging lane place; If UE is in inactive state then initiates paging to this sub-district, UE place;
S105 judges whether RNC receives that called UE replys, if receive then continue to finish the call proceeding flow process of back;
S106, if do not receive and reply, then beep-page messages are initiated in all sub-districts in this paging lane place, continue to judge whether to receive called subscriber answer, receive the call proceeding flow process of finishing the back after replying.
Below in conjunction with Fig. 1 and 2 the specific embodiment of the present invention is elaborated, should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1 be the paging principle sketch of existing WCDMA system, the CN management RNC1 and the RNC2 of WCDMA system, RNC1 manages two base stations: NODE B1 and NODE B2, UE are user terminal, and paging lane place LA1 comprises RNC1, RNC2.
In existing WCDMA system, by the called party information that transmits in public switch telephone network, the WCDMA net, after the CN parsing, determine which paging lane place this called user terminal belongs to, then beep-page message is sent to the radio network controller (RNC) of the relevant paging band of position, this radio network controller all community user terminals in this paging lane place are carried out paging.
With the WCDMA system is example, in conjunction with Fig. 1 and Fig. 2 the specific embodiment of the present invention is described in further detail.
Step (1) respectively is provided with the cell history information that a dynamic data base is preserved Thr0 (such as 8 hours) UE in the sub-district that manages in the time at radio network controller (RNC) 1, RNC2;
Step (2) is in the time of user UE1 conversation or position renewal, and radio network controller (RNC) 1 dynamically updates the cell information of this user UE1;
Step (3) radio network controller (RNC) 1, RNC2 receive the CN call signaling, require UE in the LA1 is carried out paging, and RNC1 and RNC 2 are to data base querying separately, and RNC1 obtains this user's historical cell information, such as preserving two cell history information; Here suppose the not cell history information of (such as 8 hours) in the nearest Thr0 of this UE1 hour of RNC2, so RNC2 starts paging to all the LA1 sub-districts in this RNC2 institute compass of competency.
Step (4) judges according to the historical record of UE1 in the RNC1 whether UE1 is in inactive state, such as, if twice UE1 in certain sub-district of Node B1 administration, can conclude that so thus UE1 is in inactive state, RNC1 initiates beep-page message to certain sub-district of Node B1 administration; If conclude that UE1 is in mobile status and that is to say and upgrade twice position or to call out the subdistrict position at place different, RNC1 then starts pagings to all sub-districts in the LA1 in itself institute's compass of competency;
Step (5) RNC1 judges whether to receive called subscriber answer, if receive, then continues to finish the call proceeding flow process of back;
Step (6) is if RNC1 does not receive to be replied, and then beep-page message is initiated in the sub-district in RNC1 all LA1 in itself institute's compass of competency, and follow-up flow process is then handled according to standard code.
In sum, this method judges whether UE is in inactive state, if in inactive state then carry out UE is carried out paging in cell-level, has saved the paging bandwidth effectively.
