Abstract
The invention discloses a method for searching a specific user group and a specific service number based on the WiMAX (worldwide interoperability for microwave access) local routing technology. By the method, after a request terminal acquires information, judgment and searching of local routing are skipped on the basis of the local routing technology under a same base station, a communication link with an opposite end is established quickly, and accordingly communication efficiency is improved greatly. The method includes the following steps that a user MS (mobile station) requests to an LS (location server) for commercial tenant information under the same base station, the LS extracts ASN-GW ID (access service network gateway identity) and BSID (base station identity) parameters in a request message sent from the MS, an ASN-GW of the MS is found out, the request of the MS is forwarded to the ASN-GW, and the ASN-GW processes the request of the MS based on location information to obtain a result; the base station feeds back to the request user, and then a user side actively establishes a local routing communication link under the same base station for communication.
Description
Technical field
The present invention relates to computer mobile communication technology field, looked into based on WiMAX local routing technology particularly to one kind
The method looking for particular group and special services number.
Background technology
The today receiving much concern in the development of 3G technology, WiMAX technology is as an emerging wireless broad band technology, Neng Gou
" last one kilometer " broadband connectivity made is provided in the broader territorial scope than Wi-Fi, thus supports that corporate client enjoys IT class
Service and resident have the access ability being equivalent to cable/DSL.Before its excellent performance and preferable development
Scape so as to the communications field at home and abroad all occupies a tiny space, and using as one powerful powered Communication Development.
Nowadays, developing rapidly with mobile communication technology, mobile phone is from simple call instrument to the many industry of support
The information platform development of business, location Based service business provides numerous convenience for people.
For example, mobile terminal holder can easily obtain communal facility near oneself current location or inquiry
Distribution situation：As the hospital nearest from user, bank of surrounding etc..These business are all built upon LBS（Location Based
Service, location Based service）On business.
LBS：Location Based Service, location Based service.It can pass through wireless terminal and wireless network
Network coordinates, and determines the actual position information of mobile subscriber.
Currently, to acquisition mobile terminal in LBS in IEEE802.16e standard（MS refers to mobile terminal）The overall mistake of position
Journey is as shown in Figure 1.
Wherein, the LBS reference model of WiMAX network and being described as follows of each module：
ASN（Access Service Network）：Access service network, its function is the aerial of management IEEE802.16
Interface, provides wireless access for WIMAX user.Generally by base station（BS refers to base station）And gateway（ASN-GW refers to that service accesses
Gateway）Two parts are constituted.MS is connected with BS by air interface, is linked in WiMAX network；ASN-GW is the upper of ASN network
Row outlet, is responsible for the access authentication to terminal, accesses the functions such as route, mobile IP external agent.
CSN（Connectivity Service Network）：Core Service Networks, its function is to define a set of network
The combination of function, the user for WiMAX network provides IP to connect.Generally can be by router, AAA acts on behalf of or server, user
Database, Internet pass equipment etc. forms.
Location Request（LR）：Position requests module, as One function entity, being capable of launch position request letter
Breath, asks the MS positional information that some determines.Can be outside WiMAX network（As：One external application service, is used for
The positional information of collection user）, or just in the MS entity in WiMAX network.
Location Server（LS）：Location-based service module, determines the position of MS and sends out to the entity sending position requests
Send MS positional information.It is located inside CSN, and first signaling that general LR module sends position requests is all to send LS to, comes
Allow LS network startup LBS process.That is, position fixing process is always triggered by LS in WiMAX network.
Location Controller（LC）：Position control module, inside ASN, is responsible for coordinating the measurement of MS position.
After the location measurement request that LS sends, LC should the measurement of correlation of trigger position information collecting position is determined significant
Data.Then LC provides the metrical information of MS to LS.Certainly, as long as MS is open state, LC just should grasp MS always and be connect
Service BS information.
Location Agent（LA）：Location agent module, in BS, is responsible for measurement, is collected by R6 interface to LC
Reporting measurement information.When collecting position measurement, LA passes through R1 interface and MS interactive information, is handed over LA by R8 interface
Mutually.
In conjunction with Fig. 5, the overall flow of LBS is divided into main three part：
LBS identification and licensing process：As shown in figure step 2；
Position decision process：As shown in figure step 4；
Charging process：As shown in figure step 6.
In WiMAX network, information can be provided the user according to the request of the attribute of user and user.Propose
In WiMAX local routing technical foundation, LBS business is had and more easily applies.
It is all that requesting terminal obtains target MS based on the final result of the LBS service being given in IEEE802.16E agreement
Particular location, and be used.And, LR to LS send request when, need the information comprising must have in request：Target
The mark of MS or the mandate statement being able to ensure that LR acquisition positional information.Then, LS and AAA cooperation identification and mandate, more right
The positional information of MS measures and gathers, and is calculated.Finally give the particular location of target MS, this location parameter is transferred to
Concrete application is further used.
But, under common situation, the conceivable particular location being not necessarily target in requesting terminal, and be intended to acquisition and be somebody's turn to do
The contact method of target, or be only to understand whether target close with the distance of oneself.Particularly, when mobile phone users arrive
One strange position, when needing bank or gas station, the even contact method of a garage, is can not
The telephone number of other side or terminal iidentification can be known in advance.Therefore, if energy direct access one is with regard to special service number
Tables of data supply user oneself to select, pass through to provide the particular location that other party number obtains target MS meaningful to LS than directly
Many.Particularly, reach a strange place, run into it is desirable to contact is when the garage being during the situation that car casts anchor suddenly,
If the service number of the class trade company of garage having got with mobile phone users under same BS is it is possible to it could be theoretically argued that obtain
The corresponding trade company of this service number taking and terminal geographical position close.User is receiving the merchant information that BS feedback is come
After table, select from oneself nearest number, with local routing technology for supporting, direct and trade company sets up local routing under same BS
Communication link.For the acquisition of information of trade company, eliminate the mandate after MS initiates to ask and authentication process, LS launch position are searched
The deterministic process of the local routing under the charging process of rope and same BS, saves time and resource, and can be preferably use
Family provides service.And the present invention can solve the above problems well.
Content of the invention
Present invention aim at proposing based on the lookup particular group of local routing technology and the side of special services number
Method, this method solve user send the design parameter having to know request other side during position requests problem it is achieved that
The function of other side's contact method is obtained in the case of not knowing other side's specifying information；Meanwhile, user can get current with from
Oneself is the good friend under same BS；After the method makes requesting terminal acquisition information, based on the local routing technology under same base station,

Specific embodiment
Below in conjunction with Figure of description, the present invention is described in further details.
Embodiment one
The present invention is the lookup special services number based on WiMAX network local routing technology, and it includes：
For a trade company, the geographical position in its shop be impossible the same with common mobile subscriber have ambulant.
Therefore, it can, when manager's application trade company's number of trade company, come for its distribution user name according to COS classification.
For the telephone number of 6, setting front three is COS code clerk in the present invention（Type）, latter three
Number unique mark user（Num）.For example：Set the Type=100 of bank's class；The Type=200 of food and drink class；Gas station's class
Type=300, Type=400 of garage's class etc..
Due to, in WiMAX networking, location Based service being completed by the LS module in CSN.Therefore can initially note
Database is set up in H-CSN, database top priority is telephone number and MAC Address to be mapped, for mapping during volume
Inject the differentiation in row geographical position, also should add the gateway identifier that BS is located therefore in this database（ASN-GW ID is
Refer to gateway identification number）And Base Station Identification（BSID refers to Base Station Identification）As index, to draw a circle to approve the trade company under this BS.But, right
For user, the simple number of no any descriptive information, is insignificant.Therefore, also tackle each in this database
Trade company sets up name of firm descriptive item.
Therefore, it can set up following database list in CSN：
Table 1
When mobile subscriber enters in the cell range of a BS, can be directly by the localization method based on cell ID（I.e.
BSID）, send request to V-CSN, request is in the trade company under same BS.V-CSN can search for using this BSID as search index
Database list shown in upper table, obtains corresponding number of the title+trade company of the trade company in the range of No. BSID corresponding BS of MS request
Code, and return to request user.So, user just can click on the corresponding number of trade company and carry out conversing.
But, for changeless merchant information, WiMAX network does not often need to its access information and positional information
Measure renewal, in the case that its COS and trade company's name are not all changed, when trade company networks first, pass through mirror
After determining and authorizing, subsequently avoid the need for all aliging when each communication link is set up and identified and authorize.Therefore can will be upper
Partial information in table 1 directly sets up storage list in ASN-GW, when user's request, can reducible chain further
Road, improves communication efficiency, makes directly to be transmitted between user and ASN module.One can be set up in ASN-GW individually count
According to list, for storing the merchant information that under this ASN, corresponding each BS covers.The list item of design has：No. BSID, the phone of trade company
Number, name of firm.Taking the corresponding trade company of ASN-GW ID2 in table 1 as a example, with No. BSID and merchant type sequence, newly-built list
As follows.
Table 2
In addition, for trade company's angle, either for commercial interest or other reason, any one trade company always wishes
Hope that the merchant information of oneself is obtained by people.So, the information that can set trade company can be acquired in any domestic consumer.
It is possible to after user sends position request information, solicited message directly being processed by LS, position request information is transmitted to
ASN-GW, skips the authentication process of user, and the user making directly can obtain merchant information from ASN-GW.
Under the local routing technical support based on BS, user and trade company one due to sending request are scheduled under same BS,
Can receive after the merchant information table being provided by ASN-GW that BS forwards in user, the traffic request sending to BS is built
In vertical message, an identification parameter is set, for illustrating that communicating pair is under same base station it is not necessary to BS is to user to BS
The state of terminal local business is judged.Thus, base station directly can be set up under current base station by the required parameter of user
Local routing link, communicated.
Due to WiMAX technology be proposed to solve " last one kilometer " problem.For current development, WiMAX
Three leaf deployment techniques of the lower through-put power of network, intensive net and sector base stations are so that current WiMAX network cell ratio
Cell in GSM network is less.Related data shows, the radius of society in city for the WiMAX base station can be reduced to 500 meters of left sides
Right；In rural subscriber density lower ground area, using line-of-sight transmission, radius of society can be reduced to more than ten kilometers.That is：
In urban and suburban, user obtainable with oneself trade company under same base station again, conservative estimation is not over two kilometers.By
Just know when user place sector number is in access base station, in order that the merchant location information that user obtains is from oneself
Distance have bigger availability, table 2 can be modified, the base station making be transmitted to user merchant information sequence according to
From the distance-taxis of user in this sector.As shown in table 3 below：
Table 3
Based on table 3, after having determined which sector under the BSID and this BS that MS accesses as ASN-GW（It is assumed to BSID3 pair
The sector 2 answered）.So, ASN-GW is first with BSID3 for indexing condition, the merchant information under BSID3 in search trade company table.Again
With " sector 2 " for index condition, the search corresponding merchant information in trade company table BSID3 sector 2 is it is ensured that it is in the first display；Meanwhile,
Trade company for sector 1 and sector 3 then need not especially be ranked up, and directly sequentially feeds back to user with first list.
User receive base station feedback come merchant information table after, rank the first be with oneself under same base station
The trade company of same sector.User can pass through this number, and with local routing technology for supporting, direct and trade company sets up same base station
Under local routing communication link.
Embodiment two
The present invention is the lookup particular group based on WiMAX network local routing technology, and it includes：
After user's start, in order to be able to set up the local routing based on base station, BS sets up data path for MS.Concrete signaling flow
Journey is as described in Figure 4.
Step 1：MS asks connection identifier (CID to BS（CID refers to connection identifier (CID）
Step 2：After BS receives the request message of MS, to ASN-GW request data gap marker symbol, (DPID refers to that data is led to
Road identifier), need in request message to carry the mark BSID of BS and prepare to distribute to the CID of MS；
Step 3：After ASN-GW receives the request message of BS, distribute DPID, and by BSID, CID, the ASN- in request message
GW ID and DPID sets up one-to-one relation, as shown in table 4 below, and DPID pairing BSID, CID parameter of distribution is sent out
Give BS；
Step 4：The CID distributing for user is sent to user by BS, prepares for subsequently setting up communication link.
The table 4 that ASN-GW sets up, stores user's Context form：
Table 4
BS sets up table 5, the corresponding relation of the CID and DPID of storage：
Table 5
In the present invention, after user sends the request of " good friend under same base station " to LS, carry in request message
The XML format file of friendly address list, BSID the and ASN-GW ID parameter of place base station.LS parsing obtains in the message that MS sends
After BSID and ASN-GW ID parameter, forward a request to this ASN-GW.ASN-GW receives the location request message that LS sends
Afterwards, parse and send address list good friend's number and MAC Address in the BSID asking user and XML format file.Upper table 4 is examined
MAC Address in rope buddy list whether there is.If existing, compare the BSID of this good friend and the BSID asking user whether phase
With.If identical, the good friend under the same base station of user's request during this good friend, the XML file that user is sent by ASN-GW are described
In under this same base station of friend state flag bit, and amended XML address list is finally sent to request user via base station.
After user terminal receives this XML form, change state under same base station for the address list good friend day after tomorrow, can be by user communication record
Starve good friend to be highlighted in the stem of list under same base station.
But, as long as being related to positioning or the positional information of mobile subscriber, then have to obtain the positional information of user,
Privacy concern therefore can be related to.Even, when user starts shooting, from the beginning of carrying out initial ranging with base station, just have and determined
The possibility of position.
, in order to ensure the right of privacy of user, for above-mentioned positioning idea, setting user can be on mobile terminals for the present invention
Whether setting oneself can be searched, and adds setting " stealthy " function in the instant communication terminal of subscription client.If setting
Be set to " can not search ", as domestic consumer, when other user to search both whether the function under same base station just banned
With.Although the base station that user accesses still can obtain the positional information of mobile terminal, can be prevented not by this setting
Domestic consumer obtain the positional information of oneself.And after arranging the last time, do not cancelled " stealthy " shape of oneself by user
Before state, will not be changed during the stealthy state of user.So, when user starts initial network entry, just should be in note
When volume, " stealthy " state parameter of oneself is supplied to network.To a certain extent it is ensured that while user privacy right,
Also provide users with the convenient.
On the premise of ensureing user privacy right, ASN-GW is receiving the location request message that LS forwarding comes to the present invention
Afterwards, after friend location information in user communication record being judged, update the XML file that user sends, and will be with user same
User list under base station carries out processing, make temporary table is sent to CSN, is judged with " stealthy " state to user.
Then, ASN-GW modification to this temporary table according to CSN, the modification XML file that sends of user again, this XML the most at last
