The embodiment of the present invention provides a kind of location information acquisition method, as shown in Figure 8, comprising:

Step 801, requesting service send request to create to LOCCSE, and this request to create comprises: the initial alignment cycle.

OneM2M agreement is one of ISO of the M2M communication specification that industry is generally acknowledged, the initial alignment cycle can adopt the locationUpdatePeriod parameter in oneM2M agreement to identify, this locationUpdatePeriod parameter corresponds to the interval parameter of MLP (MobileLocationProtocol, mobile location protocol).

The initial alignment cycle is normally arranged by requesting service.Concrete, requesting service can point out cycle options by user interface to user, as 10min (minute), 20min and 30min etc., user selects the locating periodically wanting to use in this cycle options, then requesting service receives the corresponding cycle options that user triggers, and locating periodically is set according to this cycle options, example, suppose that parameter corresponding to initial alignment cycle is for " locationUpdatePeriod ", the cycle options that user selects is 10min, the locating periodically that then request to create comprises is: locationUpdatePeriod=10min, this locating periodically instruction LOCCSE obtained the positional information of a target device every 10 minutes and stores, the initial alignment cycle also can input the satisfactory time by user oneself.

Step 802, LOCCSE send to requesting service and are successfully established response.

Requesting service receive that LOCCSE sends be successfully established response after, the service connection of LOCCSE and requesting service is set up.

Step 803, requesting service send adjustment indication parameter to LOCCSE.

Step 804, LOCCSE obtain cycle dynamics adjustment parameter according to adjustment indication parameter.

This adjustment indication parameter can have various ways, example, this adjustment indication parameter only can comprise indication parameter, and this indication parameter can be dynamicUpdate, there are ture and false two kinds of parameter values in this indication parameter, ture represents the adjustment allowing to position the cycle; False represents the adjustment not allowing to position the cycle, then when the indication parameter in the adjustment indication parameter that LOCCSE receives is dynamicUpdate=ture, just can position the adjustment in cycle, in the case, when indication parameter instruction allows the adjustment positioning the cycle, LOCCSE can obtain cycle dynamics adjustment parameter according to this adjustment indication parameter in this locality, it should be noted that, the parameter that the local cycle dynamics adjustment parameter obtained normally is pre-set by operator.

This adjustment indication parameter only can comprise cycle dynamics adjustment parameter, and in the case, the instruction of acquiescence adjustment indication parameter allows the adjustment positioning the cycle, and LOCCSE can directly obtain cycle dynamics adjustment parameter in adjustment indication parameter.

This adjustment indication parameter both can comprise indication parameter, comprise again cycle dynamics adjustment parameter, in the case, if indication parameter instruction allows the adjustment positioning the cycle, LOCCSE can directly obtain cycle dynamics adjustment parameter in adjustment indication parameter, if indication parameter instruction does not allow the adjustment in the cycle that positions, then cycle dynamics adjustment invalid parameters.

Cycle dynamics adjustment parameter can comprise predetermined threshold value, as threshold speed or distance threshold, also can comprise preset range, as time range and regional extent.

Step 805, LOCCSE are according to cycle dynamics adjustment parameter adjustment locating periodically.

As shown in Figure 9, LOCCSE can comprise the steps: according to cycle dynamics adjustment parameter adjustment locating periodically

Step 8051, LOCCSE obtain particular parameter value.

Cycle dynamics adjustment parameter comprises predetermined threshold value, also can comprise preset range.

When cycle dynamics adjustment parameter comprises predetermined threshold value, predetermined threshold value can comprise threshold speed, particular parameter value can be velocity parameter values, comprise: the instantaneous velocity of target device, target device are in the average speed of current locating periodically and at least one of target device in the average speed of top n locating periodically, and N is more than or equal to 1.Wherein, the instantaneous velocity of target device is the speed of target device at current time, above-mentioned threshold speed can adopt parameter velocityLimit to represent, as velocityLimit=60km (km), instruction threshold speed is 60km/h (kilometer per hour).

When cycle dynamics adjustment parameter comprises predetermined threshold value, predetermined threshold value can comprise distance threshold, particular parameter value can be distance parameter value, comprise: target device is in the distance of the finish time in M cycle and the start time in M cycle, with at least one in the average distance in M cycle, this distance can be air line distance, also can be actual displacement, M is more than or equal to 1, this M cycle can be the cycle obtaining Rule according to predetermined period, example, suppose to obtain rule according to predetermined period, this M cycle is M the cycle before current period, as M=3, average distance=(distance in the 3rd cycle before the distance+current period in the 2nd cycle before the distance+current period in the 1st cycle before current period)/3 in M cycle.Above-mentioned distance threshold can adopt parameter d istanceLimit to represent, as distanceLimit=60km, instruction distance threshold is 60km.

When cycle dynamics adjustment parameter comprises preset range, preset range can be regional extent, and particular parameter value is location parameter value, is specifically as follows the position of current target equipment.Above-mentioned zone scope can adopt parameter areaLimit to represent, this parameter areaLimit can be longitude and latitude, regular figure region, community (cell) ID (Identification, mark) and appointed area identifier in any one, wherein, regular figure region can be border circular areas, elliptical region, and appointed area identifier can be the identifier " shanghai " in Shanghai etc.

Such as, when regional extent is appointed area identifier, suppose that this appointed area identifier is " beijing ", then regional extent can comprise:

<area>

<name_area>beijing</name_area>

</area>

Now, areaLimit=beijing, inside, represent that this regional extent is that Beijing is inner.

When regional extent is regular figure region, suppose that this regular figure region is that latitude is the point of " 1393524.754 " is the center of circle, the border circular areas that 100m (rice) is radius, then regional extent can comprise with longitude for " 353524.139 ":

Now, areaLimit=is centered by specific longitude and latitude point, and radius is the border circular areas of 100m, outside, and represent that this regional extent is for centered by specific longitude and latitude point, radius is the region outside the border circular areas of 100m.

When cycle dynamics adjustment parameter comprises preset range, preset range can be time range, and particular parameter value is time parameter values, is specifically as follows current time.Above-mentioned time range can adopt parameter d urationLimit to represent, as durationLimit=9:00-12:00, inside, instruction time, scope was within 9:00-12:00.

When cycle dynamics adjustment parameter comprises predetermined threshold value, compare the size of particular parameter value and predetermined threshold value; When cycle dynamics adjustment parameter comprises preset range, compare particular parameter value whether within preset range.

Step 8053, LOCCSE determine the first locating periodically according to comparative result, and this first locating periodically is more than or equal to the initial alignment cycle.

First locating periodically can be identical with the initial alignment cycle in embodiments of the present invention, also can be different.When cycle dynamics adjustment parameter comprises predetermined threshold value, when particular parameter value is more than or equal to predetermined threshold value, determine that the first locating periodically equals the initial alignment cycle; When particular parameter value is less than predetermined threshold value, determine that the first locating periodically is greater than the initial alignment cycle.

In embodiments of the present invention, LOCCSE can set Dynamic gene, and according to the comparative result of particular parameter value and predetermined threshold value, the product obtaining this Dynamic gene and initial alignment cycle T obtains the first locating periodically.As, when particular parameter value is more than or equal to predetermined threshold value, Dynamic gene is 1, then the first locating periodically equals the initial alignment cycle; When particular parameter value is less than predetermined threshold value, Dynamic gene is 1.2, then the first locating periodically initial alignment cycle of equaling 1.2 times.Dynamic gene both can be set by operator, also can send to LOCCSE by requesting service.

It should be noted that, when predetermined threshold value is threshold speed, LOCCSE can divide different speed intervals according to this threshold speed, and corresponding each speed interval arranges corresponding Dynamic gene, and the interval of every two Dynamic gene can be identical.

Example, when threshold speed is K, corresponding particular parameter value V is compared from the different speed interval that division obtains, determines corresponding Dynamic gene B according to this comparative result, product according to this Dynamic gene and initial alignment cycle T obtains the first locating periodically T1, concrete as table 1.In Table 1, when speed interval be [K ,+∞), Dynamic gene is the 1, first locating periodically T1=T; When speed interval be [2/3K, K), Dynamic gene is the 1.2, first locating periodically T1=1.2T; When speed interval be [1/3K, 2/3K), Dynamic gene is the 1.4, first locating periodically T1=1.4T; When speed interval be [0,1/3K), Dynamic gene is the 1.6, first locating periodically T1=1.6T.Particular parameter value V is compared from the different speed interval that division obtains, works as V>=K, get B=1, then the first locating periodically T1=T; Work as 2/3K<=V<K, get B=1.2, then the first locating periodically T1=1.2T; Work as 1/3K<=V<2/3K, get B=1.4, then the first locating periodically T1=1.4T; Work as 0<=V<1/3K, get B=1.6, then the first locating periodically T1=1.6T.Wherein, particular parameter value V can comprise the instantaneous velocity of target device, target device in the average speed of current locating periodically and at least one of target device in the average speed of top n locating periodically, and N is more than or equal to 1.

[2/3K,K)	1.2	1.2T

[1/3K,2/3K)	1.4	1.4T
			[0,1/3K)	1.6	1.6T

Example, when distance threshold is H, compares between the different distance regions that corresponding particular parameter value D and division are obtained, determine corresponding Dynamic gene B according to this comparative result, product according to this Dynamic gene and initial alignment cycle T obtains the first locating periodically T1, concrete as table 2.In table 2, when distance range be [H ,+∞), Dynamic gene is the 1, first locating periodically T1=T; When distance range be [0, H), Dynamic gene is the 1.2, first locating periodically T1=1.2T.Compare between the different distance regions that particular parameter value D and division are obtained, work as D>=H, get B=1, then the first locating periodically T1=T; Work as 0<=D<H, get B=1.2, then the first locating periodically T1=1.2T.Wherein, particular parameter value D can comprise: at least one of target device in the average distance in a Distance geometry M cycle of the finish time in M cycle and the start time in M cycle, M is more than or equal to 1.

When cycle dynamics adjustment parameter comprises preset range, when particular parameter value is outside preset range, determine that the first locating periodically equals the initial alignment cycle; When particular parameter value is within preset range, determine that the first locating periodically is greater than the initial alignment cycle.Preset range is regional extent, and particular parameter value is the position of current target equipment; Or preset range is time range, particular parameter value is current time.Example, when preset range is regional extent, this regional extent is set within " beijing ", when the position of target device is " changanjie ", because particular parameter value " changanjie " is within preset range " beijing ", then determine that the first locating periodically is greater than the initial alignment cycle, suppose that the initial alignment cycle is T, Dynamic gene is 1.5, then the first locating periodically is 1.5T; When preset range is regional extent, this regional extent is set within " beijing ", when the position of target device is " shijiazhuang ", outside particular parameter value " shijiazhuang " at the regional level " beijing ", then determine that the first locating periodically equals the initial alignment cycle, suppose that the initial alignment cycle is T, then the first locating periodically is T; When preset range is time range, this time range is set within 9:00-12:00, current time is 10:20, because particular parameter value 10:20 is within time range 9:00-12:00, then determine that the first locating periodically is greater than the initial alignment cycle, suppose that the initial alignment cycle is T, Dynamic gene is 1.3, then the first locating periodically is 1.3T; When preset range is time range, this time range is set within 9:00-12:00, current time is 8:00, because particular parameter value 8:00 is outside time range 9:00-12:00, then determine that the first locating periodically equals the initial alignment cycle, suppose that the initial alignment cycle is T, then the first locating periodically is T.

It should be noted that, LOCCSE can arrange default adjusted value, be used for adjusting the interval of adjacent Dynamic gene, this default adjusted value can be 0.2, when initial alignment cycle T is larger, if T is 30min, the interval of adjacent Dynamic gene can be adjusted to and be less than or equal to default adjusted value, in order to avoid the overlong time that locating periodically elongates, cause bad Consumer's Experience; When initial alignment cycle T is less, if T is 10min, the interval of adjacent two Dynamic gene can be adjusted to and be greater than default adjusted value, both reduce the impact on Consumer's Experience, various resource can have been saved further again.It should be noted that, for different cycle dynamicses adjustment parameter, as threshold speed, distance threshold, regional extent, time range, LOCCSE can arrange different Dynamic gene, and the embodiment of the present invention does not limit this.

Optionally, it should be noted that, requesting service also can send the corresponding relation of predetermined threshold value interval and locating periodically, or, the corresponding relation of preset range interval and locating periodically is to LOCCSE, LOCCSE is according to the corresponding relation of predetermined threshold value interval with locating periodically, or preset range corresponding relation that is interval and locating periodically determines the first locating periodically.Example, also can be arranged by requesting service with the relation of the first locating periodically between the relation of the speed interval shown in table 1 and the first locating periodically or the distance regions shown in table 2, be then sent to LOCCSE, LOCCSE positions the adjustment in cycle according to corresponding relation.

It should be noted that, cycle dynamics adjustment parameter can comprise at least one in threshold speed, regional extent and time range, or comprises at least one in distance threshold, regional extent and time range.When cycle dynamics adjustment parameter has multiple, LOCCSE needs acquisition to adjust particular parameter value corresponding to parameter with the plurality of cycle dynamics, particular parameter value corresponding with it for the plurality of cycle dynamics adjustment parameter is compared, locating periodically is adjusted according to the common factor of multiple comparative result or union, example, when cycle dynamics adjustment parameter comprises threshold speed K and regional extent " beijing ", when adopting the common factor of multiple comparative result to adjust locating periodically, when velocity parameter values is less than this threshold speed K, and this location parameter is at the regional level within " beijing ", determine that this first locating periodically is greater than the initial alignment cycle, can determine that the first locating periodically or the comparison according to location parameter and regional extent determine the first locating periodically according to the comparison of velocity parameter values and threshold speed, other situations, determine that described first locating periodically equals the initial alignment cycle.

When adopting the union of multiple comparative result to adjust locating periodically, described threshold speed K is less than when meeting velocity parameter values, and any one situation of described location parameter " beijing " at the regional level, determine that described first locating periodically is greater than the initial alignment cycle; Other situations, determine that described first locating periodically equals the initial alignment cycle.

Especially, when cycle dynamics adjustment parameter has multiple, requesting service or operator also can arrange the priority of each cycle dynamics adjustment parameter, LOCCSE only can compare the highest cycle dynamics adjustment parameter of the priority particular parameter value corresponding with it, then adjusts locating periodically according to comparative result.

Especially, LOCCSE can set up Resource Unit <locationPolicy>, this Resource Unit <locationPolicy> is provided with cycle parameter dynamicPeriod, the value of the first locating periodically is stored in the cycle parameter dynamicPeriod of this Resource Unit <locationPolicy>, such as, first locating periodically is 30min, then dynamicPeriod=30min.Further, target device registered in this LOCCSE and requesting service can obtain the first locating periodically after authorizing, the i.e. value of this dynamicPeriod, target device or requesting service can show this first locating periodically to user, so that user understands the current actual location cycle.

In prior art, there is target device in one or more locating periodically, its position is the constant or very little situation of change almost, such as, target device is integrated on automobile, and this automobile runs into traffic congestion, speed limit in the process of moving, rugged hill path, sleet, the phenomenons such as fault, make this automobile be in the state of parking or low speed driving.Or target device is carried at it student, target device may most of time all only stay in certain fixed area, such as this student at 8:00-15:00 substantially all in school, then target device in the position of 8:00-15:00 almost constant or change very little.And in practical application, for user, it wishes long-term follow target device by requesting service, periodically obtain the positional information of target device, but be more concerned about the shift in position of target device, do not have vicissitudinous positional information to have little significance for certain user; For target device, if repeatedly obtain the positional information of target device, but each positional information is substantially constant, adds target device insignificant location number of times, and this location also causes the electric energy loss calculating and consume and bring in vain; For operator, in the positional information acquisition process of each target device, have repeatedly Signalling exchange, and substantially constant positional information causes the waste of network signaling overhead.Therefore, when there is target device in one or more locating periodically, its position is the constant or very little situation of change almost, and existing location information acquisition method causes the waste to computational resource, energy consumption and network overhead.

In the embodiment of the present invention, because LOCCSE determines the first locating periodically according to cycle dynamics adjustment parameter, this first locating periodically is more than or equal to the initial alignment cycle, then illustrate that the first locating periodically is compared to the elongation or constant of initial alignment cycle, within the identical time period, comparatively prior art, can reduce the acquisition number of times of the positional information of target device, when target device position almost constant or change very little, effectively reduce the waste of computational resource, energy consumption and network overhead.

Step 806, LOCCSE send position request information to target device.

LOCCSE sends position request information to target device, can comprise the first locating periodically in this position request information, in practical application, in Fig. 1, the concrete structure of M2M system 00 can be different, in different M2M system 00, the method that LOCCSE sends position request information to target device is also different.

When M2M system is the first structure, the environmental structure of M2M system 00 can be as shown in Figure 10, this M2M system 00 comprises: requesting service 01, LOCCSE02, target device 03 and location server 04, then LOCCSE can send position request information to location server, location server is after have received position request information, target device is transmitted to after this position request information is carried out protocol conversion, example, location server carries out inter-process to position request information, it is become SUPL (SecureUserPlaneLocation by MLP information, secure user plane is located) protocol information.It should be noted that, M2M system 00 environmental structure as shown in Figure 10 time, LOCCSE needs to be converted into any information that location server sends the protocol information that this location server can support, in embodiments of the present invention, position request information can be the MLP information that OMA (OpenMobileAlliance, Open Mobile Alliance) defines.The form that this position request information can increase message newly with MLP sends to location server, this MLP increases message newly and is used to indicate the numerical value of interval parameter is updated to the first locating periodically, numerical value by the interval parameter in LOCCSE and location server message is updated to the numerical value of the first locating periodically, this position request information can also comprise the ID of requesting service and the ID of target device, location server, when forwarding this position request information, can determine target device by the ID of target device.This MLP increases newly after message carries out protocol conversion and sends to target device by this location server, corresponding, the SUPL agreement between location server and target device also arranges newly-increased message, and the numerical value of locating periodically is updated to the first locating periodically.The newly-increased message of this MLP and SUPL is used to indicate the numerical value upgrading locating periodically, makes the numerical value after renewal be the numerical value of the first locating periodically.

It should be noted that, after location server receives position request information, location server can perform the initial flow process of orientation triggering with target device, by many round signalings, set up the connection of location server and target device, and carry out corresponding capability negotiation, as location capability negotiation etc.

When M2M system is the second structure, in the M2M system 00 shown in Fig. 1, be provided with GPS (GlobalPositioningSystem, global positioning system) receiver in target device 03, then LOCCSE can send position request information directly to the GPS of target device.It should be noted that, when M2M system is the second structure, requesting service, LOCCSE and target device can be integrated on same equipment, this equipment can be automobile, LOCCSE needs to be converted into any information that GPS sends the protocol information that this GPS can support, in embodiments of the present invention, position request information can be system call or JNI (JavaNativeInterface, Java call this locality) information.

When M2M system is the third structure, in the M2M system 00 shown in Fig. 1, communication unit and GPS is provided with in target device 03, then LOCCSE can send position request information to the communication unit of target device, position request information is sent to GPS by this communication unit, the function of this communication unit can be realized by application software, as M2M applications client.It should be noted that, when M2M system is the third structure, communication unit all needs to be converted into any information that GPS sends the protocol information that this GPS can support, in embodiments of the present invention, position request information can be system call or JNI information.

Step 807, target device obtain the positional information of target device according to position request information.

When M2M system is the first structure above-mentioned, target device can in the first locating periodically start time, according to position request information, by obtaining the positional information of target device with the Signalling exchange of location server.

Example, when the start time of arrival first locating periodically, the SUPL client instruction needs on target device start to position, and set up data cube computation between this SUPL client and location server.Concrete, target device can send localization message by SUPL client to location-server, instruction starts position fixing process, session id (session-ID) is carried in this localization message, position ID, the such as ability parameter of GSM community ID and SUPL client, this ability parameter comprises the method and agreement etc. of supporting location.

In concrete position fixing process, it can be the determination that target device carries out the positional information of self.When target device carries out the positional information timing really of self, mainly located by the SUPL client of target device, location server carries out assist location, target device, after the assist location parameter receiving location server transmission, calculates the positional information of self in conjunction with the main positional parameter self obtained.

When M2M system be above-mentioned the second structure or the third structure time, the GPS of target device in the first locating periodically start time, according to position request information obtain satellite information, calculate the positional information of target device according to this satellite information.

It should be noted that, this first locating periodically start time can be the moment that target device receives position request information, and also can be the moment that target device and LOCCSE arrange, the embodiment of the present invention limit this.This first locating periodically is a time cycle, and target device just obtains a positional information every this time cycle, and if this first locating periodically is 10 minutes, so target device obtained the positional information of a target device every 10 minutes.

Step 808, target device send the positional information of this target device to LOCCSE.

When M2M system is the first structure above-mentioned, in step 807, when the positional information of being undertaken self by target device timing really, the positional information of target device can be sent to location server by target device, location server, after receiving the positional information of this target device, carries out protocol conversion and is transmitted to LOCCSE.

When M2M system is above-mentioned the second structure, the positional information of acquisition is sent to LOCCSE by the GPS of target device.

When M2M system is the third structure above-mentioned, the GPS of target device sends the positional information of acquisition to communication unit, sends to LOCCSE by this communication unit.

In the standard criterion of oneM2M, if requesting service needs the positional information obtaining target device at set intervals, can in LOCCSE certain time value of parameters locationUpdatePeriod=, as locationUpdatePeriod=10min, the parameter that such LOCCSE will be arranged according to this obtains object device location information every 10min and stores.LocationUpdatePeriod is one of property parameters of Resource Unit <locationPolicy>, when Resource Unit <locationPolicy> is successfully created, corresponding memory cell <container> also creates immediately automatically, this memory cell <container> is used to the positional information storing target device, when LOCCSE receives the positional information of the target device that target device sends, just according to the information stored in this updating location information memory cell <container>.

It should be noted that, after step 806, when M2M system is the first structure above-mentioned, the positional information of target device also can be that location server carries out determining, now, mainly located by location server, the client of target device carries out assist location, location server, after the assist location parameter receiving target information transmission, calculates the positional information of target device in conjunction with the main positional parameter self obtained.Accordingly, location server sends the positional information of this target device to LOCCSE, and performs step 809.

Step 809, LOCCSE send the positional information of target device to requesting service.

As can be seen from step 806, position request information can also comprise the ID of requesting service, when then in step 808, target device returns the positional information of target device to LOCCSE, the ID of this requesting service can be carried, LOCCSE determines corresponding requesting service according to the ID of this requesting service, and sends the positional information of target device to this requesting service.

In sum, requesting service sends adjustment indication parameter to LOCCSE, LOCCSE determines the first locating periodically according to this adjustment indication parameter, according to this first locating periodically, LOCCSE obtains the positional information of target device, and because locating periodically can be determined flexibly, the triggered time point namely obtaining positional information can change flexibly, then the acquisition of positional information also can be determined flexibly, therefore improves the flexibility that positional information obtains.Simultaneously, because LOCCSE is according to cycle dynamics adjustment parameter adjustment locating periodically, first locating periodically is more than or equal to the initial alignment cycle, then illustrate that the first locating periodically is compared to the elongation or constant of initial alignment cycle, within the identical time period, comparatively prior art, can reduce the acquisition number of times of the positional information of target device, when target device position almost constant or change very little, effectively reduce the waste of computational resource, energy consumption and network overhead.
