Description

AAA realizes the method for MS location capability negotiation

Technical field

The present invention relates in the wireless communication system, be kept at when the MS stationkeeping ability in the situation of ownership place (being designated hereinafter simply as Home) authenticated/authorized/charging (being designated hereinafter simply as AAA), realize a kind of method of MS location capability negotiation.

Background technology

At present, WiMAX Forum (being designated hereinafter simply as WiMAX forum) group of networks (being designated hereinafter simply as NGW) is being formulated WiMAX positioning service (being designated hereinafter simply as LBS) second stage (being also referred to as Stage-2) standard, and the WiMAX LBS network reference model of defined as shown in Figure 1 in its standard rough draft.At first, the network configuration of existing WiMAX is done explanation, assign to from large functional areas, WiMAX comprises three parts: travelling carriage (being designated hereinafter simply as MS), access business network (being designated hereinafter simply as ASN), connection business network (being designated hereinafter simply as CSN).Wherein, ASN comprises base station (being designated hereinafter simply as BS) and access business network gateway (being designated hereinafter simply as ASN GW).

ASN is the set of a cover network function, for WiMAX user provides wireless access.Major function is Network finding and selection function, Internet protocol (being designated hereinafter simply as IP) address assignment, RRM etc.An ASN can be shared by one or more CSN.CSN is defined as the combination of a cover network function, connects for WiMAX user provides IP.The CSN function is included as the user and sets up session connection, gives mobile management between building tunnel between terminal distribution IP address, internet (being designated hereinafter simply as Internet) access, ASN and the CSN and management, the ASN etc.

In the WiMAX LBS network reference model, the module relevant with LBS comprises under non-roaming state shown in Figure 1:

(1) location-server (Location Server is hereinafter to be referred as LS)

LS is a functional entity that is positioned on the CSN, and the pass between the positioning client terminal of outside is the relation of " client＜-〉 server ", and the function of authorization check is provided for the travelling carriage of the client of outside and location request.In addition, LS also can have the function of location Calculation.

(2) register control (Location Controller is designated hereinafter simply as LC)

LC is responsible for determining and reporting positional information and the positional parameter of travelling carriage, LC can provide these positional informations and the positional parameter entity to LS, MS or other ASN inside, such as RRM (being designated hereinafter simply as RRM) module and mobile management (being designated hereinafter simply as MM) module.In case receive the request from MS, LS or ASN internal module, the measurement that LC is relevant with triggered location is collected the needed parameter of location Calculation and is carried out location Calculation.LC generally is positioned at the ASN network, if for the ASN that decomposes, then be positioned on the ASN GW.

(3) location agency (Location Agent is designated hereinafter simply as LA)

The major function of LA optionally also can be collected the parameter relevant with reporting the location to LC for carrying out the relevant measurement in location.The function of LA can be positioned at BS, MS or both have.If have the function of LA on the MS, corresponding BS also has the function of LA.

Interface between the LA on LC and the BS is the interface of ASN inside, i.e. R6 interface, and the interface between LC and the LS is Interface R3, and the interface between ASN and the ASN is Interface R4, and the interface between BS and the BS is the R8 interface.

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 standard;

202 LS and authenticated/authorized/charging (being designated hereinafter simply as AAA) are mutual, carry out the Authentication and authorization inspection.

203 because CSN connects a plurality of ASN networks simultaneously, and LS need to 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 process;

204 find the service LC of target MS after, LS sends the positioning reporting request to service LS;

205 carry out the location positioning process of ASN inside;

After 206 successful execution are finished, can obtain the positional information of target MS, LC reports this locating information to LS;

(MS or positioning client terminal) sends location response message to 207 LS to Location Request side, returns the actual position information of target MS;

208 LS send metering data to accounting server and upgrade, the professional needed expense of this LBS of deduction from requestor's account, and this process is an optional process, for some particular request, such 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 202 in the message flow be the authentication and authorization inspection.After LS received Location Request from LBS client or MS, LS sent authentication request to AAA, carried out LBS business authentication and authorization check at AAA.In AAA, preserve user's information (being called user profile in the agreement), comprising 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 (such as the time of advent poor (being designated hereinafter simply as TDOA), the time of advent (being designated hereinafter simply as RTD) etc.;

● for the CAMEL-Subscription-Information (such as the rank/type etc. of contracting) of positioning service.

Travelling carriage (being designated hereinafter simply as MS) need to be by authentication to guarantee correct contracting, and in addition, outside client also needs certified to guarantee WiMAX network and user's safety.

From only finding out that here AAA preserves the stationkeeping ability of MS with the CAMEL-Subscription-Information of locating information, how explanation does not consult and to preserve the stationkeeping ability of MS in AAA.The CAMEL-Subscription-Information of locating information is when the signatory LBS of user is professional, generally is manually at the AAA pre-save by the operator of operator.Only from here, the stationkeeping ability of MS is preserved with its CAMEL-Subscription-Information CAMEL-Subscription-Information.If 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), when in case the user has changed with the mobile terminal device of other stationkeeping abilities, the stationkeeping ability that all needs artificial regeneration MS, so unusual inconvenience.

In addition, when portable terminal by basket tooth (bluetooth) or other external equipments external during the GPS receiver module, change has namely occured in the stationkeeping ability of MS, how again to consult and upgrade stationkeeping ability not explanation in standard of MS in AAA.Do not consider that more MS is under the different conditions, be under free time (being designated hereinafter simply as IDLE) and movable (being designated hereinafter simply as ACTIVE) state such as MS, adopt which type of signaling procedure in AAA, to consult, preserve and upgrade the stationkeeping ability of MS.Need to carry out according to the stationkeeping ability information of MS owing to position the selection of algorithm, so only have the problems referred to above of having solved, could provide for the selection that in the WiMAX network, positions algorithm necessary foundation.

In addition, Huawei Company has also also proposed a kind of method of MS location capability negotiation in the manuscript of submitting to the LBS subgroup of NWG in June, 2007 in the WiMAX plenary session that Spain holds.The method of Huawei is: carry out the negotiation of MS stationkeeping ability by layer 2 or layer 3 message when MS registers to network, when MS was in the ACTIVE state, the MS stationkeeping ability was kept among the LC; When MS is in the IDLE state, the MS stationkeeping ability is kept in anchor paging controller (being designated hereinafter simply as APC) or the location register (being designated hereinafter simply as LR).When MS switches to new service ASN network, the stationkeeping ability of MS will be transferred among the new LC, when MS changes its stationkeeping ability, in being registered to the process of network these information updatings in LC.

Even in the situation that the problem of a maximum of the method for Huawei is the stationkeeping ability at MS not to be had to change, MS stationkeeping ability information also will ceaselessly shift along with the movement of MS.In addition, move to another one LC or when the IDLE state moved to another one PC/LR from a PC/LR, MS stationkeeping ability information also needed to transfer in the new entity at the ACTIVE state from a LC as MS.And work as MS and transfer under this state of ACTIVE from IDLE, the ability information of MS also needs to transfer to service LC from PC/LR.When transferring to IDLE from ACTIVE, also need to transfer to PC/LR from service LC, even so the user is not activated the LBS business, also need ceaselessly to shift in other the signaling procedure position capability information of MS, this brings certain burden to network undoubtedly.So this method of Huawei neither a simple and efficient method, does not meet the simple and practical principle of WiMAX network.
