Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The LCS system in working order down, can detect and need to judge whether or enable position information application gap not, here whether the enable position information application gap is meant and manually starts the location information request gap operating, usually manually start and also be considered as static enable position information application gap, realize by configuration order; Whether need the enable position information application gap to be meant the congestion detection mechanism dynamic detection system load condition of LCS system self and judge.At needs or under the situation of enable position information application gap, the LCS system can be by issuing location information request gap order (LCS_GAP) to the request end, the overload of its disposal ability of notice request end requires the request end to send follow-up location information request according to the indication in the LCS_GAP order.The LCS system is portability mandatory parameters such as " gap indications " in the LCS_GAP order that the request end issues, and goes back optional parameters such as portability " gap standard ", " control types ", " interstitial treatment " in the LCS_GAP order.The LCS system can send the LCS_GAP order to whole request ends or part request end, handle the flow of location information request to control himself, for example: send a large amount of delaying type position information request if LCS finds certain request end, make system be in overload state, then the LCS system can only send the LCS_GAP order to this request end, to reduce the speed that this request end sends location information request.
Mandatory parameter " gap indication " is used for the characteristic that LCS system indication request end needs the location information request of gap operating, as information such as scope effective time of location information request gap order, clearance gap.For example, the LCS system requires the request end receiving that LCS_GAP orders in the back 5000 seconds time range location information request to carry out gap operating in " gap indication ", and requiring the request end is 100 milliseconds to the minimum time clearance gap that the LCS system sends the position adjacent information request, and promptly the request end sends a location information request every 100 milliseconds to the LCS system at least.Clearance gap is used to represent that LCS requires the request end to its schedule speed that sends location information request, and the location information request in clearance gap will be spaced apart.And for example, scope effective time that the LCS system is provided with the gap order is-1, and clearance gap is 0, then show LCS system requirements request end receiving LCS_GAP order back in the time at endless the location information request carry out gap operating.For another example, scope effective time that the LCS system is provided with the gap order is 0, then shows the previous gap operating of LCS system requirements request end cancellation.
Optional parameters " gap standard " is used for the criterion of identification that LCS system indication request end needs the location information request of gap operating, combination as criterion of identification such as location information request type, object UE sign or a plurality of criterion of identification, for example, the LCS system indicates the request end that type location information request is immediately carried out gap operating in " gap standard ", or the LCS system indicates request end subtend object UE to be designated 123 location information request of initiating of type immediately in " gap standard " to carry out gap operating.Optional parameters " control types " is used for the reason of the current active position information application gap in LCS notifications request end, and possible cause value comprises " overload of LCS system " and " manually starting "." overload of LCS system " shows that the automatic enable position information application gap of LCS system congestion situation appears, in the automatic LCS of discovery of the congestion detection mechanism system in the LCS system; " manually start " and show that service management person or network manager find the congestion situation of LCS system, and some need manually start under the situation of location information request gap operating, by configuration order enable position information application gap.The priority level that " manually starts " is higher than the priority level of " overload of LCS system ", and for example, the priority level of " gap indication " in " manually starting " is higher than " gap indication " priority level in " overload of LCS system ".
Optional parameters " interstitial treatment " is used for the processing mode that LCS notifications request end stops the location information request disposed by the location information request gap operating, and possible processing mode comprises " directly refusal " and " negotiation delay "." directly refusal " shows the location information request that the direct refusal in LCS system requirements request end is disposed by the location information request gap operating, by the unaccepted reason of location information request of the corresponding real current initiation of requestor of request end notice; " negotiation delay " show LCS system requirements request end and the real requestor of the location information request initiating to be disposed by the location information request gap operating between hold consultation, determine to current location information that request postpones to handle still to cancel.If be defined as postponing to handle, then send this location information request to the LCS system in the clearance gap that in " gap indication ", allows.
Fig. 2 is information application gap one embodiment flow chart in position among the present invention, and as shown in Figure 2, the implementation procedure of location information request gap operating may further comprise the steps in the present embodiment:
Step 201～step 202:LCS system is in running order, judges whether to pass through configuration order enable position information application gap, if, execution in step 204; Otherwise, execution in step 203.
The current load condition of congestion detection mechanism dynamic detection system of step 203:LCS system need to judge whether the enable position information application gap, if desired, and execution in step 204; Otherwise, execution in step 205.For example, whether the congestion detection of LCS system mechanism dynamic detection system occupation condition reaches certain proportion, reaches 85% if system resource takies situation, then the automatic enable position information application gap of LCS system; Do not reach 85% if system resource takies situation, then LCS system enable position information application gap is not handled according to the request of normal condition location information.
Step 204:LCS system sends the LCS_GAP order to the request end, carry mandatory parameter in this LCS_GAP order, parameters such as " gap indications " for example, and portability optional parameters, for example, parameters such as " gap standard ", " control types ", " interstitial treatment " require the request end to carry out gap operating according to the parameter location information request of carrying in the LCS_GAP order.
Step 205:LCS system handles the current location information request of receiving.
In subsequent process, if the aggravation of the congestion situation of LCS system, the LCS system can continue to send the LCS_GAP order to the request end, requires the request end to carry out gap operating according to the parameter location information request of carrying in the new LCS_GAP order.For example, it is 85% o'clock that LCS system resource takies situation, and LCS system requirements request end sends a location information request every 100 milliseconds to it at least; When the occupation condition of LCS system became 95% by 85%, the LCS system can send the LCS_GAP order to the request end once more, requires the request end to send a location information request every 500 milliseconds to it at least.
If by configuration order off-position information application gap, or the load condition of LCS system has recovered normal, the LCS system can send the gap order of off-position information request to the request end, this order can be a new order that only is used for representing the off-position information application gap, it also can be the parameter of carrying in the LCS_GAP order by revising, notice request end position information application gap is closed, and gap operating is carried out in request end no longer location information request.
The current load condition of congestion detection mechanism dynamic detection system when LCS system self, judge when needing the enable position information application gap, the automatic enable position information application gap of LCS system, in the LCS_GAP order, can " gap indication " parameter be set by the LCS system is 5000 seconds effective time, clearance gap is 100 milliseconds, show in 5000 seconds time ranges of LCS system requirements request end after receiving the LCS_GAP order all location information request carried out the location information request gap operating that this moment, the request end can not be less than 100 milliseconds to the time interval of LCS system transmission continuous position information request.
Further, go back " gap standard " parameter that portability indication request end needs the location information request criterion of identification of gap operating in the LCS_GAP order, for example, the LCS system can be provided with " gap standard " parameter and be " delaying type position information request ", and then interstitial treatment is only carried out for the delaying type position service request in the request end; Can also carry " control types " parameter of the current active position information application gap of notice request end reason in the LCS_GAP order, for example, LCS can be provided with " control types " parameter and be " overload of LCS system ", and the former of promptly current active position information application gap congestion situation occurs because of the LCS system.In addition, also can be in the LCS_GAP order by carrying the processing mode of " interstitial treatment " parameter indication request end to the delaying type position information request disposed by the location information request gap operating, for example the indication request end directly refuses to initiate the real requestor of this delaying type position information request, and carries corresponding error cause value.
Arrive the load condition of LCS system recovers just often when the congestion detection mechanism dynamic monitoring of LCS system self, the LCS system can send the LCS_GAP order to the request end equally, in this LCS_GAP order, scope effective time that can be provided with in " gap indication " parameter by the LCS system is an invalid flag, for example 0 second, notice request end position information application gap is closed, and gap operating is carried out in request end no longer location information request.If in LCS_GAP orders effective 5000 seconds time ranges, the load condition of LCS system is recovered just often, the LCS system can send similar off-position information request gap order to the request end equally, require the request end no longer the location information request carry out gap operating.
When the administrative staff of LCS system find that the LCS system is in the overload situation, during by configuration order enable position information application gap, it is static enable position information application gap, the LCS system sends the LCS_GAP order to the request end, requires the dip transmission rate of information request of request end.Follow-up implementation procedure and said process are basic identical.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
