Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and system of property performance period positioning service in global inserting of microwave interoperability (WiMAX, WorldInteroperability for Microwave Access) network.
Background technology
WiMAX is based on the wireless access wide band technology of IEEE 802.16 standards, can effectively utilize limited radio spectrum resources and larger bandwidth of air-interface (the data transmission capabilities of the highest 70Mbps) is provided.Its network is by registration terminal/portable terminal (SS/MS), access business network (ASN) and be connected three logic entities of business network (CSN) and form, each logic entity has represented one group of functional entity, and each function can or be distributed in a plurality of physical equipments at single physical and realize.
ASN is mainly WiMAX user corresponding wireless access and control is provided, and under WiMAX network decomposition model, mainly comprises ASN-GW (ASN Gate-Way, ASN gateway) and BS (BaseStation, base station).(authentication device Auth.) is an important network element among the ASN to Authenticator, under the ASN decomposition model, is positioned at ASN-GW.Auth. major function is to provide the access authentication service to terminal when terminal networks.Simultaneously, Auth. also records the contextual information relevant with terminal, the mode of operation current such as terminal (active mode, idle pulley etc.) etc.Be called terminal the Anchor Auth. (anchor point authentication device) of the Auth. of above-mentioned service for this terminal is provided.
CSN provides the IP Connection Service for MS.When the user roamed, CSN was divided into visit CSN (V-CSN) and ownership CSN (H-CSN).AAA (authentication authorized charging server) is an important network element among the CSN, and its major function is to preserve contracted user's files on each of customers; Record a series of contextual informations relevant with terminal, such as current Anchor Auth. of terminal etc.; Authentication Authorization and billing function to various requests are provided.
LBS (Location Based Services, location-based service) is a kind of important service that the WiMAX network provides.The current location of in the WiMAX network, measuring and measuring target terminal, and to carrier network inner or outside authorized entity provides the terminal location that records.LBS function based among the WiMAX can realize multiple value increasing service.
The LBS reference model as shown in Figure 1, main entity comprises the LS (LocationServer that is arranged in CSN, location-server), LC among the ASN (Location Controller, register control) and LA (Location Agent, location agency) and to be positioned at the WiMAX network inside and outside or be positioned at the LR (Location Requestor, Location Request side) of terminal.Under roaming scence, LS can be divided into H-LS (Home-LS, the LS in the home network) and V-LS (Visited-LS, the LS in the visit net), lay respectively among the H-CSN and V-CSN in.LC is responsible for coordinating BS and MS implements location survey, obtains measurement data; LS is responsible for implementing location Calculation according to measurement data, obtains the positional information of MS.
The basic principle that positioning service realizes is when LS receives the Location Request of mandate, at first goes up the Anchor Auth. that AAA inquires about the target terminal that is positioned, and then the positioning reporting request is sent to this Anchor Auth..Anchor Auth. finds current LC for the target terminal service, and issues the positioning reporting request to this service LC, finishes location survey by LC, and to the report of LS restoring to normal position, last by the position of LS according to this report computing terminal.So mutual between LS and the LC, namely how LS obtains the emphasis that positioning reporting is WiMAX LBS research.
Positioning service has two kinds of service modes: disposable positioning service and periodically positioning service.Fig. 2 is disposable positioning service schematic flow sheet in the existing method, is characterized in that LS issues one-time positioning report request, and LC returns the one-time positioning report; Figure 3 shows that in the existing method the periodically realization flow schematic diagram of positioning service, be characterized in that LS issues one-time positioning report request, by LC take cycle T as the time interval repeatedly the restoring to normal position report come property performance period location.
In the scheme of existing property performance period positioning service, periodically realized by LC.There are problems:
Carrying out in the process of periodicity location sessions, LC need to preserve the therewith relevant contextual information of location sessions, such as method of measurement, and measuring period etc.The MS that is positioned can switch between ASN inside or ASN, and the switching of MS often is accompanied by the migration of its service LC, therefore ASN need to have the function of processing the service LC migration, need between new and old service LC, transmit contextual information, by the continue periodicity location sessions of old LC of new LC.This has increased certain complexity for system in realization.Especially, when the locating measurement method that adopts after old LC and the LS negotiation can not be supported in new LC or can not reach the required precision of appointment, LS again can't with new LC again consultation parameter, then periodically location sessions can't effectively continue even be forced to end.
And carrying out in the process of periodicity location sessions, the MS that is positioned can enter idle pulley at any time.After the MS that is positioned entered idle pulley, the LC resource that is arranged in ASN will be released, and LC can't continue to provide positioning reporting to LS periodically, had caused periodically positioning service to be forced to end.If permission terminal without restriction arbitrarily passes in and out idle pulley, terminal can be in the periodicity position fixing process entering and exitting from idle mode repeatedly, particularly in the situation that the cycle shorter, this repeatedly enter and withdraw from can occur very frequent.Not only greatly increase the expense of network and terminal, and can cause the time delay of certain location, even can affect the normal use of terminal, finally cause user's experience to be had a greatly reduced quality; Otherwise, if in the process of periodically locating, force terminal never to enter idle pulley, particularly in the long-term situation of periodicity location sessions, can cause the hydraulic performance decline of terminal, as increase battery consumption, equally also can cause user's experience to descend.Finally causing the LBS business to be carried out meets difficulty.
Therefore be necessary whether decision-making allows terminal access idle mode to carry out in the cycle position fixing process.
In addition, come property performance period location with existing method, in whole process, only allow LS and LC to consult one-time positioning and measure relevant parameter, can't be in the process that location sessions carries out according to the variation of actual conditions and dynamically, revise neatly such as method of measurement, certainty of measurement, parameter and the attributes such as measuring period.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is described in further detail, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
In existing technology, the request that MS enters idle pulley all can be passed among the anchor point authentication device Anchor Auth. of described MS, judges by Anchor Auth. whether MS can enter idle pulley.Therefore, in the cycle position fixing process, the Anchor Auth. of the MS that is positioned has the decision-making resource that MS enters idle pulley that whether allows to be positioned.
Adopt the method for the invention, in the cycle position fixing process, send the positioning reporting request to the Anchor Auth. of the MS that is positioned periodically by LS, comprise in the request and describe periodic parameter; Described Anchor Auth. distinguishes the type of positioning service, and whether decision-making needs to stop terminal access idle mode; LC is responsible for coordinated measurement and reports to the LS restoring to normal position.Reached thus the purpose that solves the problems referred to above with flow process control mode flexibly.
For example in the situation that the cycle is shorter, Anchor Auth. can stop terminal access idle mode; Otherwise in the situation that the cycle is long, Anchor Auth. allows terminal to enter idle pulley between twice location survey.Again for example, even locating periodically is longer, but Anchor Auth. still stops terminal access idle mode according to strategy and the professional needs of carrying out of locality.Perhaps, even locating periodically is shorter, but Anchor Auth. thinks entering of repetition and exitting from idle mode for the resource consumption of terminal and network, and the time delay that causes in this process all can be accepted, perhaps time of continuing of this cycle location sessions is shorter, it is little that Anchor Auth. thinks that in this process terminal repeating enters the possibility that exits from idle mode, and then also can not stop terminal access idle mode.
In addition, the prevention portable terminal that is positioned enters idle pulley and can also depend on strategy among the LS, if LS itself does not wish to stop terminal to enter idle pulley in the periodicity position fixing process, then in the positioning reporting request that it periodically issues, the suitable location relevant parameter of described cycle that arranges, what make that Anchor Auth. do not think current LS request is that the one-period positioning instant can.
In a word, cycle location relevant parameter that LS provides and the strategy of operator are depended in this decision-making fully.
And this decision-making can be carried out when Anchor Auth. receives the positioning reporting request, also can carry out when Anchor Auth. receives the request that the described MS of being positioned request enters idle pulley.
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Embodiment one
Fig. 4 is the cycle positioning flow schematic diagram of the embodiment of the invention one, and as shown in Figure 4, its step specifically comprises:
Step 101: cycle Location Request direction location-server LS initiates the cycle Location Request; LS and aaa server are to the Location Request Authentication Authorization; Location-server obtains the Anchor Auth. of the portable terminal that is positioned by AAA.
Step 102:LS take locating periodically as the time interval, generates the positioning reporting request according to the demand of Location Request periodically, comprises in the request to describe periodic parameter.These parameters comprise the sign (for example describing with Transaction-ID) of the cycle location that can represent uniquely that described positioning reporting request is affiliated; The parameter (for example describing with T) of locating periodically can be described; The parameter (such as describing with C) of required location number of times etc. can be described.Then the positioning reporting request is sent to the Anchor Auth. of the MS that is positioned.
Fig. 5 is that the LS of the embodiment of the invention one processes positioning reporting request schematic flow sheet, and in conjunction with Fig. 5, described step 102 specifically may further comprise the steps 102a to step 102g:
Step 102a: location-server LS generates the positioning reporting request periodically take locating periodically as the time interval.
Step 102b:LS judges the task of current required execution.If will finish a current ongoing periodicity location sessions, execution in step 102e then, otherwise execution in step 102c.
Step 102c:LS judges the task of current required execution.If the positioning reporting request that this sends is the last request in current ongoing cycle location, the type that namely is equal to described positioning reporting request is disposable Location Request, is execution in step 102f then, otherwise carries out 102d.
Step 102d:LS arranges in above-mentioned positioning reporting request and periodically relevant parameter, as above-mentioned parameter T is set, C etc., and carry out 102g.
Step 102e:LS arranges in above-mentioned positioning reporting request and can show the parameter that finishes this cycle location, and carries out 102g.
Step 102f:LS arranges suitable parameter in above-mentioned positioning reporting request, the type that shows current positioning reporting request is last request in this cycle location, and the type that namely shows current positioning reporting request is disposable Location Request, and carries out 102g.
Step 102g:LS increases such as Transaction-ID in the positioning reporting request, the parameters such as the IP address of LS.And the positioning reporting request that assembles sent to Anchor Auth..
In step 102, definable above-mentioned parameter C value is the one-period location greater than the described positioning reporting request of 1 expression; It is a disposable location that the C value equals the described positioning reporting request of 1 expression; The type that the C value equals the described positioning reporting request of 0 expression is to stop the current period location.
In step 102d, can make parameters C＞1 so, what expression was this time asked is take the cycle location of Transaction-ID as identifying.Concrete, for example make T=10, C=50, the expression locating periodically is 10 seconds, and the location number of times is 50 times, and then the duration of the location of the cycle under this positioning reporting request is 500 seconds; In step 102e, make parameters C=0, what expression was this time asked is to stop current cycle location take Transaction-ID as sign; In step 102f, make C=1, what expression was this time sent is the last request of the cycle location take Transaction-ID as sign, namely the type of this positioning reporting request is a disposable location.
Step 103: the Anchor Auth. of the MS that is positioned resolves in the positioning reporting request of being sent by location-server and describes periodic parameter, judge the type of this positioning reporting, whether decision-making stops terminal access idle mode, and the state parameter that is associated with described cycle location that this locality is preserved carries out corresponding operating.
Described state parameter can comprise following some fields: [Transaction-ID, T, C, Termination ID, timestamp when state generation or renewal ... .], wherein Transaction-ID can be used as the index sign of above-mentioned state parameter, by Transaction-ID can be unique a described state parameter and one-period location are mapped.
Described state parameter is not limited only to represent simply allow or do not allow terminal access idle mode, also can represent by the field in the state parameter such as being with permission with good conditionsi or not allowing etc.
Fig. 6 is the schematic flow sheet that the anchor point authentication device of the portable terminal that is positioned of the embodiment of the invention one is processed the positioning reporting request, and in conjunction with Fig. 6, described step 103 specifically may further comprise the steps 103a to step 103i:
Step 103a:Anchor Auth. receives the positioning reporting request from location-server, and resolves and describe periodic parameter.Such as, these parameters comprise Transaction-ID, T and C etc.
Step 103b: by Parameter analysis of electrochemical, if above-mentioned positioning reporting request is the one-period Location Request, execution in step 103c then, otherwise execution in step 103f.
Whether step 103c:Anchor Auth. decision-making needs to stop terminal access idle mode, and decision-making can be according to multiple precondition.Such as, Anchor Auth. does decision-making according to the strategy of configuration in conjunction with describing periodic parameter in the positioning reporting request, and for example the cycle just stoped less than 10 seconds, otherwise did not stop.If determine to stop then execution in step 103d, otherwise execution in step 103e.
Step 103d:Anchor Auth. (for example searches state parameter that local cycle location that preserve and described is associated, search the state take Transaction-ID as index): if exist, then upgrade this described state parameter, for example update cycle T measures the fields such as number of times C and timestamp; Otherwise create a new state parameter, arrange corresponding field and with it and current cycle location are associated, Transaction-ID wherein for example is set, the fields such as T and C.Wherein, use Transaction-ID to be associated with the current period location as index.After this, execution in step 103i.
Step 103e:Anchor Auth. searches the state parameter that local cycle location that preserve and described is associated, if exist, then deletes it.After this, execution in step 103i.
Step 103f:Anchor Auth. searches the state parameter that local cycle location that preserve and described is associated, if exist, then deletes it.After this, execution in step 103g.
Step 103g: if above-mentioned positioning reporting request is a disposable Location Request (for example, showing it is last positioning reporting request in the one-period location sessions), execution in step 103i then, otherwise execution in step 103h.
Step 103h:Anchor Auth. abandons the positioning reporting request, finishes whole positioning flow.Subsequent step 104 to step 108 will no longer be carried out.
Step 103i:Anchor Auth. does necessary processing to the location relevant parameter of the cycle in the above-mentioned positioning reporting request, such as deleting the fields such as T and C, execution in step 104.
Step 104:Anchor Auth. sends to the positioning reporting request on the register control of the portable terminal that is positioned by Anchor ASN.
Step 105: under the coordination of positioning service controller, finish the measurement report collection to the MS that is positioned.
Step 106: register control is reported to the location-server restoring to normal position.
Step 107: location-server calculates the positional information of MS when measured according to the positioning reporting that register control returns.
Step 108: location-server returns to cycle Location Request side with result of calculation.
So far, to step 108, finished the one-time positioning process in the cycle position fixing process by execution in step 101.After this by LS according to the cycle, repeat above-mentioned steps 102 to step 108, but performance period the location, until whole cycle location sessions finishes.For follow-up request, Anchor Auth. can make a strategic decision whether need to stop terminal access idle mode again.
In the implementation of cycle location sessions, when Anchor Auth. received that the requesting terminal enters the request of idle pulley, Anchor Auth. need to check whether terminal satisfies the condition that enters idle pulley.These conditions comprise the local effective described state parameter that is associated with the cycle location that preserve of Anchor Auth..
If location-server finishes the one-period location sessions with the method for abandoning sending the positioning reporting request, and when the end period location sessions, do not point out Anchor Auth. to stop current ongoing cycle location, then can be not deleted with the described state parameter of this cycle positioning associated.Yet this state parameter will be an invalid state parameter, so Anchor Auth. need to know that those state parameters are effectively, and those state parameters are invalid, and state parameter that will be invalid is deleted.Following method can guarantee the validity of above-mentioned state parameter.
Anchor Auth. can take out the current described state parameter that has existed periodically one by one, and these state parameters are investigated, and Anchor Auth. is thought the deletion of invalid state parameter.
Perhaps, Anchor Auth. takes out all described state parameter relevant with target terminal when receiving that the requesting terminal enters the request of idle pulley, and these state parameters are investigated, and AnchorAuth. is thought the deletion of invalid state parameter.
For example, if the timestamp that records in the above-mentioned state parameter and present time difference of the time cycle T of asking much larger than location-server (such as, the former is the latter's twice), can think that then state parameter is invalid.The determination methods that other can certainly be arranged.
Embodiment two
In the first embodiment, whether Anchor Auth. decision-making when receiving the periodicity Location Request needs to stop terminal access idle mode in the process of cycle location.Further, decision-making can occur in Anchor Auth. and receives when the requesting terminal enters idle pulley.Below in conjunction with Fig. 7 the second embodiment of this technical scheme is described in further detail.
Step 201, step 202: detailed step is with step 101 and step 102.
Step 203: the Anchor Auth. of the MS that is positioned resolves in the positioning reporting request of being sent by location-server LS and describes periodic parameter, and the state parameter that is associated with described cycle location that this locality is preserved carries out corresponding operating.
Described state parameter can comprise following some fields: [Transaction-ID, T, C, Termination ID, timestamp when state generation or renewal ... .], wherein Transaction-ID can be used as the index of above-mentioned state parameter, by Transaction-ID can be unique a described state parameter and one-period location is mapped.
Described state parameter is used for supporting Anchor Auth. when receiving that the MS that asks to be positioned enters the request of idle pulley, and whether decision-making stops it to enter idle pulley.For example, state parameter can be periodic one group of parameter of describing this cycle location.
Fig. 8 is the schematic flow sheet that the anchor point authentication device of the portable terminal that is positioned of second embodiment of the invention is processed the positioning reporting request, and in conjunction with Fig. 8, described step 203 specifically may further comprise the steps 203a to step 203g:
Step 203a:Anchor Auth. receives the positioning reporting request from location-server, and resolves and describe periodic parameter.Such as, these parameters comprise Transaction-ID, T and C etc.
Step 203b: by Parameter analysis of electrochemical, if above-mentioned positioning reporting request is the one-period Location Request, execution in step 203c then, otherwise execution in step 203d.
Step 203c:Anchor Auth. (for example searches state parameter that local cycle location that preserve and described is associated, search the state take Transaction-ID as index): if exist, then upgrade this described state parameter, for example update cycle T measures the fields such as number of times C and timestamp; Otherwise create a new state parameter, corresponding field is set and it and current cycle location are associated, setting Transaction-ID wherein for example, the fields such as T and C.Wherein, use Transaction-ID to be associated with the current period location as index.After this, execution in step 203g.
Step 203d:Anchor Auth. searches the state parameter that local cycle location that preserve and described is associated, if exist, then deletes it.After this, execution in step 203e.
Step 203e: if above-mentioned positioning reporting request is a disposable Location Request (for example, showing it is last positioning reporting request in the one-period location sessions), execution in step 203g then, otherwise execution in step 203f.
Step 203f:Anchor Auth. abandons the positioning reporting request, finishes whole positioning flow.Subsequent step 204 to step 208 will no longer be carried out.
Step 203g:Anchor Auth. does necessary processing to the location relevant parameter of the cycle in the above-mentioned positioning reporting request, such as deleting the fields such as T and C, execution in step 204.
Step 204 is to step 208: detailed step with step 104 to step 108.
In this second embodiment, Anchor Auth. is when receiving the periodicity Location Request, be not made at once the decision-making that whether stops terminal access idle mode in the process of cycle location, but simply will be recorded in Anchor Auth. this locality with periodically relevant information with the form of state parameter in this request.
When Anchor Auth. receives that the requesting terminal enters the request of idle pulley, Anchor Auth. just checks associated state parameter, under these state parameters still effective condition, the information such as bonding state parameter and strategy, whether dynamic decision-making needs to stop terminal access idle mode.
The above-mentioned result of decision will enter one of Rule of judgment of idle pulley as the final refusal of Anchor Auth. or receiving terminal.
Anchor Auth. need to know that equally which state parameter is that effectively which state parameter is invalid, and can be with invalid periodic status deletion.Guarantee Status effective method described in the first embodiment here stands good so.
