Background technology
In wireless communication system, location-based service is the most important applications after note.The location-based service technology is to obtain terminal user position information (latitude and longitude coordinates) by wireless network, under the support of electronic map platform, provides the value-added service of respective service for the user then.
Some business of carrying out at present all are passive acceptance location, perhaps in needs, just carry out location service request one time.Such as the situation of child, old man in the own residing positional information of inquiry, on every side facility, the families such as food and drink, bank, gas station, cinema, thereby carry out dispatching management or the like.Some business so do not combine the characteristics and the location-based service technology that constantly move of terminal, are unfavorable for integrating the using value chain of upstream and downstream yet, transfer professional provider and professional recipient's enthusiasm.Such as market, eating and drinking establishment, cinema, need improve the use of information to releasing news by active push services apart from the potential customers in its certain limit.The user also wishes when obtaining relevant information, can automatic reception arrive own required information.
But because present technical limitations, the characteristics that portable terminal is constantly moved do not combine with existing location-based service technology, therefore, can't accomplish the current location according to portable terminal, by system to the needed relevant information of terminal active push.
Summary of the invention
Technical problem solved by the invention has been to provide a kind of method that active push services is provided according to terminal location, the location-based service technology is combined with the characteristics that portable terminal constantly moves, according to the current location of portable terminal, by system to the needed relevant information of terminal active push.
For solving the problems of the technologies described above, the invention provides a kind ofly provides the method for active push services according to terminal location, is used for the position service sub system of wireless communication system, and this method comprises the steps:
(1) position, Service coverage and the content distributed information of service distribution end are set at the network side of wireless communication system;
(2) described position service sub system regularly detects the current location of user terminal, and whether the current location of calculating this terminal is in the Service coverage of described service distribution end;
(3) if this terminal is within the Service coverage of service distribution end, then content distributed information is initiatively pushed to this portable terminal by network side;
The positional information of described service distribution end is the latitude and longitude information of service distribution end; Described user terminal current location information is the current latitude and longitude information of user terminal.
Utilize the present invention, the location-based service technology that not only can make wireless communication system can be according to user's needs and the passive positional information that provides, and can when portable terminal moves to diverse location, can initiatively push relevant information according to user's customization to the user.
Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is described in further detail.
Fig. 1 is the implementing procedure schematic diagram, and as shown in the figure, location-based service realizes that the implementing procedure of active push is:
Step 101: positional information and Service coverage that the service distribution end is set at network side.Compare with these 2 indexs and terminal location later, determine whether within the service propelling scope.Positional information determines that according to longitude and latitude Service coverage can be provided with as required, within 100 meters, 50 meters of circumferences or the like.
Step 102: at network side the information presenting substance of service distribution end is set, information can be by autonomous issue of issue end and autonomous the renewal.
Step 103: the business of some type that customization oneself needs, and setting-up time filtercondition.The temporal filtering condition, being last time pushes time gap current time poor of the type business to this user terminal, in 3 days, the business information of the same type that provides of same issue end just can not repeat to receive like this, this is for being avoided in the short time, when passing by the somewhere repeatedly, receive same information repeatedly.
Step 104: the position service sub system in the wireless communication system regularly detects the residing position of terminal of custom service, and regularly sense cycle also can be provided with as required, such as 5 minutes, detects once in 10 minutes.Also the volume of business that can bear according to network and the needs of practical business accuracy are adjusted sense cycle.When the condition permission, also can come according to the needs of volume of business and professional accuracy sense cycle is adjusted dynamically.Sense cycle is short more, and the resource that takies network is just many more, but accuracy is just high more, can reduce the scope of passing by issuing service, but the probability that does not receive information has also increased.
Step 105: more whether the distance between the longitude and latitude of the longitude and latitude of position service sub system computing terminal and service distribution end is within the coverage of service distribution end.
Step 106:,, then can not push this business information if not the type of service of customization if end within coverage, checks then whether the user has customized the type business.
Step 107: if customization such business, reexamine whether meet the temporal filtering condition, if be within the filtration time, such as within 3 days, show that this user has received the same item information that the same issue end provides, and then no longer sends pushed information.
Step 108:, then content distributed information is initiatively pushed to this portable terminal by network side if above-mentioned condition all satisfies.Can push with way of short messages during active push, at present push the business information of its customization with way of short messages to the user, be most convenient and ripe a kind of mode.Active push also can initiatively push to content distributed information PDA (Personal Digital Assistant, personal digital assistant), also can utilize E-mail mode that content distributed information is initiatively pushed to this portable terminal.
In the present invention, the position service function that wireless communication system is provided, the characteristics that constantly move with terminal combine, by position service sub system cycle detection terminal positional information, whether comparison terminal is in professional range of receiving, and and information publisher, informant, the business of customization etc. combines, when making terminal move to different positions, network side initiatively pushes corresponding information to it, and terminal can in time receive the corresponding information of consumer premise.The present invention provides an approach that releases news and platform for the information publisher, and the user also can in time receive Useful Information on one's own initiative, be service supplier, information publisher, made up a complete value chain between the end user, further integrated the resource of the upstream and downstream of location-based service technology, transfer service supplier and information publisher's enthusiasm, attract that a large amount of potential craving for provide fast, the timely user of traffic information services, excavate the huge information of in mobile communication and location-based service technology combine, being contained and unite value.
