Fig. 2 has shown the applied environment according to the paging method of embodiments of the invention 1.
As shown in Figure 2, terminal 1 is arranged in the overlapping covered of WCDMA and WiMAX network.
The following describes specific implementation process according to the paging method of embodiments of the invention 1.
In the present embodiment, terminal 1 can be worked under WCDMA and WiMAX pattern, is dual-mode terminal.WiMAX is as a kind of arbitrary way of WCDMA, so the air interface of WCDMA is in open mode always, just opens the air interface of WiMAX when only being necessary.
When terminal 1 overlapping covered mobile in heterogeneous network, its needs are operated under the WCDMA pattern, and the air interface of WiMAX is in closed condition to save energy.And terminal 1 is carried out the position renewal in the WCDMA network, and the location message of terminal uploads to VLR Visitor Location Register (VLR) and local (HLR) storage by the base station in the WCDMA network, upgrades and needn't carry out the position simultaneously in the WiMAX system.
When the paging request that exists from the WCDMA system, base station and RNC utilize the positional information that is stored among the HLR to carry out paging, utilize this positional information then, find the concrete paging domain at the purpose terminal place of paging request, send beep-page message then, this is consistent with paging mechanism of the prior art, is not described in detail in this.
When the paging request that exists from the WiMAX system, and in the present embodiment for easy, the hypothesis goal terminal is a terminal 1, because the WiMAX pattern of terminal 1 is in closed condition, so network node (SGSN/VLR in the WCDMA system, GGSN, HLR) whether the purpose terminal of searching the paging request of WiMAX system is operated under the WCDMA network schemer, be operated in terminal 1 under the situation of WCDMA network schemer, control subsystem in the WCDMA system (RNC and base station) is carried out the isomery paging by add new information unit in the idle bit of the beep-page message of WCDMA, the beep-page message that is to say WiMAX is to send to terminal 1 by the base station in the WCDMA system, and the notice dual-mode terminal has beep-page message at another network.This process need utilizes terminal to carry out the paging domain at the purpose terminal place of the paging request that the position updated information searches the WiMAX system in the WCDMA pattern.
Here, because the network node in the WCDMA system utilizes terminal to carry out the position updated information in the WCDMA pattern, whether the purpose terminal of searching corresponding to the paging request of WiMAX system is operated in the WCDMA network schemer, so in the present embodiment, network node in the WCDMA system possesses the function of the network node (AG, SS) in the WiMAX system accordingly, that is, can discern the paging request in the WiMAX system, and can in the WiMAX system, carry out the position and upgrade.In simple terms, the function that possesses of the network node in the present embodiment (SGSN/VLR, GGSN, HLR) is the combination of function of the network node of network node among traditional WCDMA and WiMAX system.
Here, it should be noted, because terminal 1 is a dual-mode terminal, so can think directly that also this purpose terminal is to be operated in the WCDMA network schemer; And if purpose terminal (terminal 1) is for multimode terminal and when being arranged in a plurality of networks overlapping covered, network node in then a plurality of networks can be searched this purpose terminal works under any network schemer, if this purpose terminal works is when the 3rd network schemer, then the control subsystem in the 3rd network is carried out the isomery paging by add new information unit in the idle bit of the beep-page message of the 3rd network.
Get back in the situation shown in Figure 2, in the WCDMA system, when endpoint registration after network, this terminal will be assigned to a paging group.When beep-page message need send to any one terminal in this paging group, paging indication (PI, paging indicator) will appear on the Page Indication Channel (PICH) periodically.
In case detect PI, terminal is deciphered next down channel (PCH) frame that sends by auxiliary publish control physical channel (CCPCH) carrying, to confirm whether to have one's own beep-page message; When PI indication decision reliability reduced, terminal also needed the frame coding to PCH equally.
The frequency that paging indication occurs is more little, and then the number of times that wakes up from park mode of terminal is just few more, and the life-span of battery is also just long more.
Fig. 3 has shown the paging channel structure that adopts in embodiments of the invention 1.
As shown in Figure 3, when the paging request that exists from the WiMAX system, paging indication (PI, pagingindicator) appear on the Page Indication Channel (PICH), and then comprise general paging information (UPI) in next down channel (PCH) frame, this UPI information representation paging is from the WiMAX system.For example, the value that can pre-determine in system from the paging information UPI of WCDMA is 0, is 1 from the value of the paging information UPI of WiMAX.If when having a plurality of network in system, UPI also can be made as the value corresponding to each network accordingly.
Fig. 4 has shown the message flow chart according to the paging method of embodiments of the invention 1.
As shown in Figure 4, the node GGSN in the core net of WCDMA system searches the base station at the purpose terminal place of paging request in node SGSN/VLR via HLR by command M T LOOK-UP when the paging request W-PR that receives from the WiMAX network.
Find the base station at purpose terminal place of paging request in node SGSN/VLR after, node SGSN/VLR comprises the information of the base station that is found to node GGSN response MT LOOK UP CONFIRM message.
Node GGSN sends UP MESSAGE to this base station that finds according to the information of the base station that finds under the control of RNC, to transmit paging request W-PR.Here, RNC and base station also are referred to as control subsystem.
Paging indication information UPI (shown in the PCH among Fig. 3) is upgraded according to paging request W-PR in this base station that finds, and sends the PCH frame.
The purpose terminal of paging request W-PR is after to the PCH frame coding, obtain the indication (from the paging of WiMAX network) of isomery paging according to UPI, open the WiMAX air interface, be linked into the WiMAX network then and communicate (wherein, information element is added in ADD IE (add Information element) expression).
Thus, utilize the air interface of WCDMA to realize terminal is carried out the purpose of WiMAX ICQ.The position is upgraded and can be carried out in the WCDMA network simultaneously, also can carry out in the WiMAX network after the WiMAX air interface is opened.
Fig. 5 has shown the structural representation according to the terminal of embodiments of the invention 1.
As shown in Figure 5, terminal 1 comprises processing unit 11, access interface 12, updating block 13 and detecting unit 14.
Updating block 13 is used for carrying out Location Registration and renewal on starting up of terminal or suitable opportunity such as district more to system.Access interface 12 can comprise the interface of a plurality of network schemers, is used for being connected to communicate with corresponding network, and in the present embodiment, access interface 12 comprises WCDMA air interface and WiMAX air interface.
Detecting unit 14 is used for detecting whether there is the paging indication on the Page Indication Channel by the WCDMA air interface, if exist, then the notifier processes unit 11.
After detecting unit 14 detects the paging indication, decipher by the next downlink frame that the auxiliary publish control physical channel carrying sends 11 pairs of base stations of processing unit, to confirm whether to have the beep-page message that belongs to this terminal 1 oneself, if have, then further judge the indication (UPI) whether the paging of expression heterogeneous network is arranged in this paging information, if UPI=1, then trigger and open corresponding network interface (WiMAX air interface), otherwise (UPI=0) still utilize the WCDMA air interface to finish the paging request.Here, for example, suppose that the value that pre-determines UPI in system is that 0 expression is the paging information from WCDMA, the value of UPI is that 1 expression is the paging information from WiMAX.
Certainly, processing unit 11 in the dual-mode terminal can judge directly whether this paging information represents to exist the paging request from the WiMAX network, if have then directly trigger and open the WiMAX air interface, which network and the processing unit 11 in the multimode terminal is judged UPI indication in the paging informations is, and triggers and open corresponding network interface.
Here; when bimodulus or multimode terminal are in the heterogeneous network overlapping region; the position that updating block 13 is carried out is upgraded and can be realized in the WCDMA system, also can realize in the WiMAX system after opening the WiMAX air interface, upgrades and needn't all carry out the position in WCDMA system and WiMAX system.
