In addition, message flow is as shown in Figure 2 end to end in the Wimax network of defined in the Wimax LBS Stage-2 standard rough draft.Its step comprises:
201 MS or LBS client are initiated positioning service, can send locating request message to location-server LS by positioning client terminal or MS, and the message between positioning client terminal and the location-server does not define in this standard;
202 LS and authenticated/authorized/charging (being designated hereinafter simply as AAA) are mutual, authenticate the inquiry with security information.
203 because CSN connects a plurality of ASN networks simultaneously, and LS need look for a service ASN at MS (the being designated hereinafter simply as target MS) place that is positioned, and transfers to the LC that is positioned at service ASN GW and handle;
204 find the service LC of target MS after, LS sends the positioning reporting request to service LC;
205 carry out the position deterministic process of ASN inside;
After 206 206 successful execution are finished, can obtain the positional information of target MS, LC reports this locating information to LS;
207 LS send location response message to Location Request side (MS or positioning client terminal), return the actual position information of target MS;
LS sends metering data to accounting server and upgrades, the professional needed expense of this LBS of deduction from requestor's account, and this process is an optional process, for some particular request, as emergency services, Lawful Interception etc., do not need to pay, thereby do not need to carry out this step yet.
In the Wimax LBS Stage-2 standard rough draft in the Wimax network of defined end to end the step 205 in the message flow carry out the position deterministic process of ASN inside, mainly be at first to select corresponding location algorithm according to the stationkeeping ability of request type, required precision and the target MS of positioning service by the LC (perhaps LS) that serves, and then execution position fixing process, promptly Fu Wu LC (perhaps LS) need know the stationkeeping ability of MS, mainly comprises following information:
● whether each mobile station equipment has the GPS receiver;
● the Wimax stationkeeping ability whether each mobile station equipment is supported to strengthen is (as the time of advent poor (being designated hereinafter simply as TDOA), the time of advent (being designated hereinafter simply as RTD) etc.;
Need know the stationkeeping ability of MS at the LC/LS the process of providing of positioning service as can be known from foregoing description, the stationkeeping ability of MS also may change in addition, if for example mobile terminal device and Subscriber Identity Module are separable words (at present the Wimax terminal of Samsung be exactly mobile terminal device and Subscriber Identity Module are separable), in case the user has changed other mobile terminal devices, the stationkeeping ability of MS also may change so; In addition, when portable terminal by basket tooth (bluetooth) or other external equipments external the GPS receiver module, the stationkeeping ability of MS also can change.
Therefore network need be preserved the stationkeeping ability of MS, and also can upgrade the stationkeeping ability of MS when the stationkeeping ability of MS changes accordingly.Intel proposes the stationkeeping ability of MS is kept at AAA, and Huawei proposes when MS is in the IDLE state, and the stationkeeping ability of MS is kept at APC, when MS is in ACTIVE, the stationkeeping ability of MS is kept at the LC of service.But they only are the descriptions that provides notion, do not provide concrete method and corresponding flow process.The stationkeeping ability that how to upgrade MS does not in addition illustrate in standard yet.
