Wherein, the area coordinate information in required parameter refers to a plurality of coordinate informations of the peripheral extent that asked peripheral distance or decision are asked.
When described area coordinate information is asked peripheral distance, the mode that builds the memory request zone is:
The position coordinates of the mobile terminal of initiating subscribe request of take is the center of circle, and the described peripheral distance of take is made circle as radius and obtained memory request zone (memory request zone A as shown in Figure 2).
When a plurality of coordinate information that described area coordinate information is the decision peripheral extent of asking, the mode that builds the memory request zone is: with described a plurality of coordinate points, as irregular polygon, obtain the memory request zone.
After structure obtains the memory request zone, method of the present invention has also further created its corresponding memory request buffering area according to constructed memory request zone, as the buffer area B in Fig. 2.Wherein, the scope of described memory request buffering area comprises and is greater than the memory request buffering area; The size of memory request buffering area can be arranged as required by the user.On Memory Map, the current position coordinates point that just can judge easily which mobile terminal is in the scope in memory request zone like this, or in memory request buffering area scope.
Step S204: background server initiatively is pushed to satisfactory information the mobile terminal of initiating subscribe request;
Background server will get the current position coordinates point at step S203 and drop in the scope in memory request zone, or the information of the mobile terminal in memory request buffering area scope initiatively is pushed to the mobile terminal of initiating subscribe request.The concrete mode pushed is:
Background server is according to the required parameter (resource class, hierarchical resource) of the mobile terminal of initiating subscribe request, the surrounding resources information (information of mobile terminal) that will meet required parameter is carried out layering, classification processing according to required parameter, surrounding resources information after processing is assembled into respectively to corresponding message bag and sends in the transmission message queue, background server will send the message queue active push to the mobile terminal of initiating subscribe request.
Adopt framing signal (real time position coordinate information) is set up to the memory headroom map in present embodiment, and all mobile terminal locations all are mapped on this memory headroom map, while the neighboring area request of client also being mapped to memory object simultaneously, by region decision on the memory headroom map, thereby obtain fast the situation of surrounding resources.In the situation that the change in location frequency of mobile terminal and surrounding resources is very high, more can show advantage.
