Method for negotiating location capability, system and equipment in the microwave access global intercommunication network

Technical field

The present invention relates to the communications field, particularly the location capability negotiation technology in the communications field.

Background technology

IEEE802.16 is (the Institute of Electrical andElectronics Engineers of Institute of Electrical and Electronics Engineers, be called for short " IEEE ") in promulgation in December calendar year 2001, the standard that provides last kilometer WiMAX to insert at metropolitan area network is provided.

Meanwhile, numerous equipment and establishment supplier have formed micro-wave access to global intercommunication (WorldwideInteroperability for Microwave Access, abbreviation " WiMAX ") tissue of forum, its purpose is to accelerate the deployment based on the broadband wireless network of above-mentioned IEEE802.16 series standard by guaranteeing broadband wireless access compatibility of apparatus and interoperability.Therefore, under normal conditions, the system that uses the realization WiMAX access of stipulating in 802.16 series standards is called the WiMAX system.

WiMAX network wireless side is based on the wireless MAN access technology of IEEE 802.16d/e standard.What now mainly follow is IEEE 802.16-2004 (802.16d) standard of formulating in July, 2004.IEEE802.16-2004 (802.16d) standard operation frequency range be 2GHz to 11GHz, be to authorize and unauthorized mixing frequency range.Adopt OFDM (Orthogonal Frequency Division Multiplexing, be called for short " OFDM ") and OFDM access (Orthogonal Frequency Multiple Access, abbreviation " OFDMA ") physical layer, effectively anti-multipath decline.Under the optimum channel decline situation, transmission rate can be approached 75Mbps.IEEE 802.16-2004 (802.16d) standard is used for the non line of sight point-to-multipoint technology of metropolitan area network, mainly is the form of fixing and nomadic network, has added the technology of supporting simple mobile communication and full mobile communication among the IEEE802.16e that is discussing.

Fig. 1 shows the end-to-end reference model of WiMAX.As can be seen, WiMAX mainly comprises travelling carriage (Mobile Station, be called for short " MS ")/subscriber station (Subscribe Station, abbreviation " SS "), access service network (Access Service Network, be called for short " ASN ") and connectivity serving network (Connectivity Service Network is called for short " CSN ").

ASN is defined as the network function set that the wireless access service is provided for the WiMAX user terminal, ASN has comprised base station (Base Station, be called for short " BS ") and ASN gateway (ASN Gate Way is called for short " ASN-GW ") network element, an ASN may be shared by a plurality of CSN.

The major function of ASN comprises the function of base station and the function of ASN-GW.Wherein, the function of base station has: provide that the base station is connected with the L2 of subscriber station SS/MS, the compression and the encryption of RRM, measurement and the power control and the data of eating dishes without rice or wine.The function of ASN-GW has: for SS/MS authentication function provides agency (proxy) function; Support the network of NSP to find and selection; For SS provides relaying (Relay) function of L3 information, as IP address assignment.

CSN is defined as to the WiMAX user terminal IP is provided Connection Service.CSN mainly provides the IP address assignment of following function: SS/MS, Internet inserts, checking, mandate, charging protocol (Authentication, Authorization, Account, be called for short " AAA ") agency (proxy) or service (server), authorization control based on the user, ASN is to the tunnel of CSN, WiMAX user's charging and the clearing between the operator, tunnel under the roaming condition between the CSN, switching between the ASN and various WiMAX service (as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business).

MS/SS is (moving) subscriber equipment, and the user uses this devices accessing WiMAX network.

Wherein, the R1 interface is a wireless air interface, is mainly defined by IEEE802.16d/e.All the other interfaces are wireline interface.

More than the WiMAX network is introduced, below the wireless location technology of more and more widely being used at present is introduced.

The research of wireless location technology starts from the automatic vehicle location system of the sixties in 20th century, and this technology is widely used in scopes such as public transport, taxi dispatching and public security tracking subsequently.Afterwards, along with the Requirement Increases of people to location-based information service, wireless location technology obtains more researchers' concern, global positioning system (Global Position System, abbreviation " GPS ") appearance makes that more wireless location technology has produced qualitative leap, positioning accuracy is greatly enhanced, and can reach in 10 meters.

Along with the development of mobile communication industry, professional innovation has become the basic motive force of network and technical development.Simultaneously, the operation mode of new business changes, and healthy value chain then is the basic assurance of new business development.At present, voice service is still the main body of mobile communication business, and various novel mobile value-added service and mobile data services then are the powerful points of economic increase in mobile communication market.Moving communicating field is one of most hotly competitive in recent years industry, operator more and more needs the business of otherness to enhance competitiveness, a kind of mobile value-added service that location service (LoCation Services is called for short " LCS ") is generally had an optimistic view of, and will obtain to develop rapidly.

Though directly utilize GPS can reach a kind of comparatively desirable locating effect, he needs special receiving equipment, is not very convenient concerning most of users.In recent years, along with popularizing of cellular mobile system, location technology begins to be used for aspects such as cellular system design, switching, service area are determined, traffic monitoring.

Location-based business (Location Based Service, be called for short " LBS "), claim shift position business or positioning service again, be meant that the mobile network obtains the geographical location information (latitude and longitude coordinates) of user terminal by specific location technology, offer user, communication system or third party, and by the support of certain electronic map information, for the mobile subscriber provides relevant with its position, calling or non-calling class service.The professional initial U.S.'s 911 urgent calls that are applied as in shift position.In June, 1996, U.S. Federal Communications Committee (FCC) requires each mobile operator that the user position information of all-calls 911 numbers must be able to be provided.The commerce of location service is applied to develop in recent years comparatively fast, the many operators such as the SPRINT of the U.S., Japan and Korea S, AT﹠amp; T Wireless, NTT DoCoMo, KDDI, J-Phone, SKT, KTF, H3G etc. have begun the commercialization of shift position business.The positioning service based on the sub-district has also been carried out in Europe, as E-plus, and Orange.The two big mobile operator of China are also disposing mobile location service separately energetically, wherein adopt UNICOM's CDMA positioning service of GPSone also to start operation.Expectation is in the coming years, and the mobile location service market scale of China will present the sustainable growth of acceleration.

Simple location-based service can be provided in the 2G system of early deployment, and at present along with the quickening of the commercial process of 3G network, location service can rely on broadband, the characteristic at a high speed of 3G network, become more rich and varied.According to the progress curve of Japanese NTT DOCOMO WVAS, data service 5% with relevant with positioning service.

In 3G network, the positioning service that Japan and some company of Britain provide can be for the user provides in detail, the numerical map of real-time update is informed user's particular location, and can guide the user to seek hotel, dining room, shop and some other user's interest commercial facility by electronic chart.

At present, at third generation partner program (3rd Generation Partnership Project, be called for short " 3GPP ") and 3GPP2 in for the location capability negotiation of terminal in the localization method and network clear and definite and perfect flow process has been arranged all, can make network or terminal can know that in decision the other side has or not the located in connection ability before the other side sends Location Request, thereby can select suitable localization method according to the ability that the other side supports, perhaps directly refusal sends locating request message to the opposite end that does not possess stationkeeping ability, reduces the unusual and meaningless wait in the position fixing process.

Though in the WiMAX network system, SPWG (service provider working group) agreement also requires to support the user is positioned, do not propose as yet at present a kind of in the WiMAX network terminal and network position the method for capability negotiation.

Embodiment

For the purpose, technical scheme and the advantage that make embodiment of the present invention is clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.

In embodiment of the present invention, terminal need be passed through medium access control (Media AccessControl, being called for short " MAC ") message, L3 (layer 3) message of layer or the high level set up between the network entity of this terminal and ASN be connected, the stationkeeping ability relevant information of self is sent in the network entity of ASN, as ASN-GW.Because the contextual function of the terminal of preservation is just arranged among the ASN-GW originally, be only so the terminal positioning ability is kept at ASN-GW.Network side can pass through corresponding response message, the common factor information of the stationkeeping ability of the stationkeeping ability relevant information of answer network side or the stationkeeping ability of network side and this terminal.Following several mode is specifically arranged:

(1) terminal is by mailing to network entity (promptly serving ASN-GW) with the stationkeeping ability relevant information of terminal as a message part in SBC-REQ message.Network entity (service ASN-GW) is after having received SBC-REQ message then, with the common factor information of the stationkeeping ability of the stationkeeping ability of the stationkeeping ability relevant information of network or network and this terminal, be included among the SBC-RSP (terminal basic capacity response) and feed back to terminal.Thereby finish the capability negotiation between terminal and the network.This SBC-REQ and SBC-RSP message are carried the stationkeeping ability relevant information by extended field.

(2) terminal is by mailing to network entity (service ASN-GW) with the stationkeeping ability relevant information of terminal as a message part in REG-REQ message.Network entity (service ASN-GW) has been after having received REG-REQ message then, with the common factor information of stationkeeping ability with the stationkeeping ability of this terminal of the stationkeeping ability relevant information of network or network, is included among the REG-RSP (registration responds) and feeds back to terminal.Thereby finish the capability negotiation between terminal and the network.This REG-REQ and REG-RSP message are carried the stationkeeping ability relevant information by extended field.

(3) terminal mails to network entity (service ASN-GW) with the stationkeeping ability relevant information of terminal in by L3 message in ISF (business initial stream) passage.Network entity (service ASN-GW) has been after having received this L3 message then, informs the common factor information of the stationkeeping ability of the stationkeeping ability of the stationkeeping ability relevant information of terminal network or network and this terminal by replying message.Thereby finish the capability negotiation between terminal and the network.The stationkeeping ability relevant information is carried in the field of expansion.

(4) terminal in " MO-LR (Mobile Origination-Location Request) " locating request message that network entity (service ASN-GW) sends carried terminal the stationkeeping ability relevant information, network entity (service ASN-GW) carries the common factor information of the stationkeeping ability of the stationkeeping ability of the stationkeeping ability relevant information of network or network and this terminal in the feedback message of replying then.Thereby finish the capability negotiation between terminal and the network.The stationkeeping ability relevant information is carried in the field of expansion.

(5) set up a high level that is used to transmit carry the stationkeeping ability related information messages between network entity (service ASN-GW) and terminal and connect, by this connection, terminal will comprise the stationkeeping ability relevant information and mail to network entity (service ASN-GW).Network entity (service ASN-GW) carries the common factor information of the stationkeeping ability of the stationkeeping ability of the stationkeeping ability relevant information of network or network and this terminal in replying message then.Thereby finish the capability negotiation between terminal and the network.

After network entity (service ASN-GW) is received the stationkeeping ability relevant information of terminal, this stationkeeping ability relevant information is preserved.

Need to prove, if by SBC process or REG process interface stationkeeping ability relevant information, then after BS has received the message of stationkeeping ability relevant information of carried terminal, need inform service ASN-GW to the stationkeeping ability relevant information of this terminal, service ASN-GW tissue is replied, again by BS the common factor information of the stationkeeping ability of the stationkeeping ability of the stationkeeping ability relevant information of network support or network and this terminal, feed back to terminal.

Wherein, the stationkeeping ability relevant information of terminal comprises: the localization method of support and the relevant ability in location, when estimating ability, the support of round-trip delay (Round Trip Delay, be called for short " RTD ") or not being supported in Idle state the report measurement result ability, Location Request notified the tenability of flow process.Wherein, localization method comprises with the relevant ability in location: the terminal supplementary observation time of advent poor (Observed TimeDifference Of Arrival is called for short " OTDOA ") method, the OTDOA method based on terminal, terminal agps system GPS method, the GPS method based on terminal, traditional GPS method.

The stationkeeping ability relevant information of network comprises the localization method and the relevant ability in location of support, localization method comprises with the relevant ability in location: the terminal supplementary observation time of advent poor (Observed Time DifferenceOf Arrival is called for short " OTDOA ") method, the OTDOA method based on terminal, terminal agps system GPS method, the GPS method based on terminal, traditional GPS method.

After terminal is moved, the stationkeeping ability relevant information of this terminal is by the transmission between network entity, guarantee that the current service ASN-GW of this terminal obtains the stationkeeping ability relevant information of this terminal, and the stationkeeping ability relevant information that current network is supported or with the common factor information of the stationkeeping ability of this terminal, be notified to this terminal.

Such as the stationkeeping ability relevant information of terminal is kept among the service ASN-GW, and each terminal moves to after the different ASN-GW, by context transfer message the stationkeeping ability relevant information of this terminal is passed to new service ASN-GW.If the stationkeeping ability relevant information of this terminal also is kept at Anchor (anchor point) ASN-GW, then this terminal moves to after the different ASN-GW each time, in the contextual information of Anchor ASN-GW requesting terminal, the contextual information by terminal brings new service ASN-GW with the stationkeeping ability relevant information of this terminal.After terminal under the activated state moved under the new service ASN-GW, new service ASN-GW can inform the stationkeeping ability relevant information of terminal about this ASN-GW by RNG-RSP (ranging response) message through expansion; Perhaps by SBC or REG process and this terminal interaction stationkeeping ability relevant information; Perhaps in the ISF passage, carry out stationkeeping ability relevant information mutual between terminal and the new service ASN-GW by L3 message; With this allow stationkeeping ability relevant information that terminal knows that current network is supported or with the common factor information of the stationkeeping ability of this terminal.

Say that for another example terminal is switching to following time of target ASN-GW, target ASN-GW obtains the stationkeeping ability relevant information of terminal and the stationkeeping ability relevant information of informing this ASN-GW of this terminal by BS by the end message request message that is used for request contexts.In this process,, then need between BS and target ASN-GW, position ability request-related information and information exchange if BS does not temporarily also know the stationkeeping ability relevant information of target ASN-GW.BS is by initiatively sending SBC-RSP/REG-RSP message to terminal, in this message, comprise target ASN-GW the stationkeeping ability relevant information or with the common factor information of the stationkeeping ability of this terminal, inform the stationkeeping ability relevant information that this terminal current network is supported; Perhaps the stationkeeping ability relevant information by in RNG-RSP (ranging response) message, carrying network or with the common factor information of the stationkeeping ability of this terminal, position the mutual of ability relevant information; Perhaps in the ISF passage, position the mutual of ability relevant information by L3 message.

After terminal and network side position ability relevant information mutual, if terminal transfers Idle state (idle) to from activated state (active), then network side is saved to paging controller (Paging Controller with the stationkeeping ability relevant information of this terminal, be called for short " PC "), when terminal under Idle state, when a paging domain under PC management moves under another paging domain, if migration (relocation) process of Anchor (anchor point) PC has taken place, then new anchor point PC obtains the stationkeeping ability relevant information of terminal to original anchor point PC.After this terminal transferred activated state to from Idle state, the stationkeeping ability relevant information of this terminal that anchor point Anchor PC will preserve sent the current service ASN-GW of this terminal to.That is to say, if outer room begins to call out this terminal, in order to allow this terminal and new service ASN-GW can know the other side's location correlation energy force information as soon as possible, in re-networking process, finish the mutual of stationkeeping ability relevant information, PC tells new service ASN-GW stationkeeping ability relevant information about terminal, BS goes into MAC layer message in the network process by terminal then, and as RNG-RSP/SBC-RSP/REG-RSP etc., or L3 message is informed the stationkeeping ability relevant information of terminal about network.

After network moves, particularly serve ASN-GW had change after, the stationkeeping ability relevant information of network side need be handed down to terminal again, specifically can be by following several modes:

If the current activated state that is in of terminal, then in the Perodic ranging process of this terminal, notify by RNG-RSP message, or in the message of MAC layer or L3 message, notify, or be connected with high level between the current service ASN-GW of this terminal by setting up this terminal, notify;

If network side does not possess stationkeeping ability, then after receiving the stationkeeping ability relevant information of terminal, mistake occurs or do not return corresponding response message by returning the response message indication, do not possess stationkeeping ability so that allow this terminal judges go out the current network side, such as, as terminal by " MOLR " locating request message (L3 message a kind of) or network again or the stationkeeping ability relevant information of this terminal of REG-REQ/SBC-REQ message informing network side, network side mistake occurs or does not return corresponding response message by returning the response message indication, makes this terminal judges draw network side and does not possess stationkeeping ability;

If the current Idle state that is in of terminal, then transfer to the process of activated state from Idle state in this terminal, by notifying through the RNG-RSP message of expansion, or after this terminal transfers activated state to, in the message of MAC layer or L3 message, notify, or the high level of between terminal and current service ASN-GW, setting up be connected in message transfer, notify.

If the stationkeeping ability relevant information of terminal changes, the stationkeeping ability relevant information after then will changing is notified to network side.Such as terminal by the mode of online updating, makes terminal have new ability after access network.The stationkeeping ability relevant information that this moment, terminal needed the informing network side to have about this terminal.So that can carrying out suitable locate mode at terminal, network selects, to satisfy the QoS requirement of positioning service.

The mode that terminal can adopt has: the stationkeeping ability relevant information of the L3 information carried terminal by the ISF passage, perhaps be connected the message that transmission carries the stationkeeping ability relevant information, perhaps when terminal is initiated " MOLR " Location Request, send to network side by the high level of setting up between current service ASN-GW and the terminal.If terminal after having upgraded ability, can be initiated to network again, then the ability of this terminal just can send to network side by the signaling procedures such as SBC-REQ/REG-REQ when networking again.

More than be that network entity with ASN serves as that service ASN-GW is that example describes, the network entity of ASN can also be anchor point ASN-GW.If terminal sends to anchor point ASN-GW with the stationkeeping ability relevant information of self, and do not send to service ASN-GW, then this anchor point ASN-GW needs the stationkeeping ability relevant information of this terminal is sent to service ASN-GW.

Below by each execution mode, various situations described above are specifically described respectively.

First execution mode of the present invention relates to method for negotiating location capability in the WiMAX network, and idiographic flow as shown in Figure 2.

In step 210, the SBC-REQ message of terminal by sending in going into network process is notified to network side with the stationkeeping ability relevant information of this terminal self.Specifically, by SBC-REQ message is expanded, extended mode is as follows: the different bits of each that will expand are used to represent different stationkeeping abilities, the concrete numerical value of each bit wherein is used to represent whether the support of corresponding stationkeeping ability (is not supported as 0 expression, 1 expresses support for), the stationkeeping ability relevant information of terminal self is sent to network side by the SBC-REQ message in going into network process.Wherein, the localization method that the stationkeeping ability relevant information comprises support and the relevant ability in location (as terminal supplementary observation difference time of advent OTDOA method, OTDOA method, terminal agps system GPS method, GPS method, traditional GPS method) based on terminal based on terminal, when estimating ability, the support of round-trip delay RTD or not being supported in Idle state the report measurement result ability, notify the tenability of flow process to Location Request, more complete sum is comprehensive to make the negotiation of stationkeeping ability.

Then, enter step 220, BS by and the interacting message of service between the ASN-GW, notification service ASN-GW is about the stationkeeping ability relevant information of terminal.If also do not serve the stationkeeping ability relevant information of ASN-GW on the BS, then also obtain the stationkeeping ability relevant information of service ASN-GW by interacting message.The stationkeeping ability relevant information of service ASN-GW comprises the localization method and the relevant ability in location of support, as terminal supplementary observation time of advent difference OTDOA method, OTDOA method, terminal agps system GPS method, the GPS method based on terminal, traditional GPS method based on terminal, more complete sum is comprehensive to make the negotiation of stationkeeping ability.

Then, enter step 230, BS carries the stationkeeping ability relevant information of service ASN-GW in SBC-RSP message.Similarly, by SBC-RSP message is expanded, each different bits of expansion are used to represent different stationkeeping abilities, the concrete numerical value of each bit wherein is used to represent whether the support of corresponding stationkeeping ability (is not supported as 0 expression, 1 expresses support for), the stationkeeping ability relevant information of network side is sent to terminal by SBC-RSP message.

Need to prove that what carry in SBC-RSP message can be the stationkeeping ability relevant information of all supports of network side, also can be the common factor information of the stationkeeping ability and the stationkeeping ability that terminal is supported of network side support.

Because the Signalling exchange of SBC-REQ/SBC-RSP is the signaling process that terminal and network side need carry out, therefore, what can make stationkeeping ability need not extra signaling process alternately, has saved system resource.And owing to realized the location capability negotiation between the terminal and network side in the WiMAX network, make the positioning control functional entity and/or the terminal of network side send locating request message to the other side in decision, or before a certain localization method is taked in decision, can know localization method and stationkeeping ability that the other side supports, thereby location quality of service requires and the localization method of terminal support to select suitable can satisfying, or require the terminal of location under network side entity has the situation of the localization method that support asks, just to initiate Location Request, avoid meaningless Signalling exchange flow process, saved the communication resource.

And because the Signalling exchange of SBC-REQ/SBC-RSP is to carry out in going in the network process of terminal, therefore, network side and terminal can more promptly obtain the other side's stationkeeping ability.

Second execution mode of the present invention relates to method for negotiating location capability in the WiMAX network, and idiographic flow as shown in Figure 3.

In step 310, terminal is by sending the REG-REQ message of expansion in going into network process, and the stationkeeping ability relevant information of this terminal self is notified to network side.

In step 320, BS by and the interacting message of service between the ASN-GW, notification service ASN-GW is about the stationkeeping ability relevant information of terminal.If also do not serve the stationkeeping ability relevant information of ASN-GW on the BS, then also obtain the stationkeeping ability relevant information of service ASN-GW by interacting message.

Then, enter step 330, BS sends to terminal by the REG-RSP message of expansion with the stationkeeping ability relevant information of network side.

Be not difficult to find, the present embodiment and first execution mode are roughly the same, its difference is, in the first embodiment, terminal and the network side SBC-REQ/SBC-RSP signaling message by expansion mutual positions the negotiation of ability, and in the present embodiment, REG-REQ/REG-RSP signaling message by expansion mutual positions the negotiation of ability.What make stationkeeping ability need not extra signaling process alternately, has saved system resource.Owing to realized the location capability negotiation between the terminal and network side in the WiMAX network, make the positioning control functional entity and/or the terminal of network side send locating request message to the other side in decision, or before a certain localization method is taked in decision, can know localization method and stationkeeping ability that the other side supports, thereby location quality of service requires and the localization method of terminal support to select suitable can satisfying, or require the terminal of location under network side entity has the situation of the localization method that support asks, just to initiate Location Request, avoid meaningless Signalling exchange flow process, saved the communication resource.

And the Signalling exchange of REG-REQ/REG-RSP equally also is to carry out in going in the network process of terminal, and therefore, network side and terminal also can more promptly obtain the other side's stationkeeping ability.

The 3rd execution mode of the present invention relates to method for negotiating location capability in the WiMAX network, and idiographic flow as shown in Figure 4.

In step 410, terminal is after going into network process, by the relevant capabilities message in location of carried terminal support in the L3 message that sends in the ISF passage.Specifically, by L3 message is expanded, each different bits of expansion are used to represent different stationkeeping abilities, the concrete numerical value of each bit wherein is used to represent whether the support of corresponding stationkeeping ability (is not supported as 0 expression, 1 expresses support for), the stationkeeping ability relevant information of terminal self is sent to network side by L3 message.Wherein, the localization method that the stationkeeping ability relevant information comprises support and the relevant ability in location (as terminal supplementary observation difference time of advent OTDOA method, OTDOA method, terminal agps system GPS method, GPS method, traditional GPS method) based on terminal based on terminal, when estimating ability, the support of round-trip delay RTD or not being supported in Idle state the report measurement result ability, notify the tenability of flow process to Location Request, more complete sum is comprehensive to make the negotiation of stationkeeping ability.

Then, enter step 420, service ASN-GW carries the stationkeeping ability relevant information of service ASN-GW by L3 message in the ISF passage.Similarly, by L3 message is expanded, each different bits of expansion are used to represent different stationkeeping abilities, the concrete numerical value of each bit wherein is used to represent whether the support of corresponding stationkeeping ability (is not supported as 0 expression, 1 expresses support for), the stationkeeping ability relevant information of network side is sent to terminal by L3 message.

Wherein, the stationkeeping ability relevant information comprises the relevant ability of localization method and location, as differing from terminal supplementary observation time of advent OTDOA method, OTDOA method, terminal agps system GPS method, the GPS method based on terminal, traditional GPS method based on terminal.

Need to prove that what carry in L3 message can be the stationkeeping ability relevant information of all supports of network side, also can be the common factor information of the stationkeeping ability and the stationkeeping ability that terminal is supported of network side support.

Mistake do not occur if service ASN-GW replys the message content indication of message or answer, then terminal judges current service ASN-GW does not possess stationkeeping ability.

In the present embodiment, realized location capability negotiation between terminal and the network side by L3 message, make the positioning control functional entity and/or the terminal of network side send locating request message to the other side in decision, or before a certain localization method is taked in decision, can know localization method and stationkeeping ability that the other side supports, thereby location quality of service requires and the localization method of terminal support to select suitable can satisfying, or require the terminal of location under network side entity has the situation of the localization method that support asks, just to initiate Location Request, avoid meaningless Signalling exchange flow process, saved the communication resource.

The 4th execution mode of the present invention relates to method for negotiating location capability in the WiMAX network, and idiographic flow as shown in Figure 5.

In step 510, terminal is after going into network process, and the high level of setting up between terminal and the service ASN-GW that transmits the message that comprises the stationkeeping ability relevant information that is specifically designed to connects.

Then, enter step 520, terminal sends the stationkeeping ability notification message in service ASN-GW, carry the stationkeeping ability relevant information of this terminal in this stationkeeping ability notification message.Specifically, each different bits in this stationkeeping ability notification message are used to represent different stationkeeping abilities, the concrete numerical value of each bit wherein is used to represent whether the support of corresponding stationkeeping ability (is not supported as 0 expression, 1 expresses support for), the stationkeeping ability relevant information of terminal self is sent to network side by this stationkeeping ability notification message.

Wherein, the localization method that the stationkeeping ability relevant information comprises support and the relevant ability in location (as terminal supplementary observation difference time of advent OTDOA method, OTDOA method, terminal agps system GPS method, GPS method, traditional GPS method) based on terminal based on terminal, when estimating ability, the support of round-trip delay RTD or not being supported in Idle state the report measurement result ability, notify the tenability of flow process to Location Request, more complete sum is comprehensive to make the negotiation of stationkeeping ability.

Then, enter step 530, service ASN-GW carries the common factor information of the stationkeeping ability of the stationkeeping ability of the stationkeeping ability relevant information of network side or network side and this terminal in stationkeeping ability is replied message.Similarly, each different bits in this answer message are used to represent different stationkeeping abilities, the concrete numerical value of each bit wherein is used to represent whether the support of corresponding stationkeeping ability (is not supported as 0 expression, 1 expresses support for), the stationkeeping ability relevant information of network side is sent to terminal by this answer message.
