Description
Technical field
The present invention relates to a kind of implementation of positioning service interface in wireless telecommunication network system, relate in particular to the implementation of PHS wireless local telephone system positioning service interface.
Background technology
Along with growing stronger day by day of PHS Personal Handyphone System(PHS) market, China Telecom and China Netcom have begun to consider to provide the value-added service service of radio local telephone network.The location-based service business becomes the focus of new business gradually along with the development in mobile communication technology and market.In order to help the business development of PHS network site, make things convenient in the business of PHS network site interconnected between each network element device and make things convenient for business function to provide, China Telecom has worked out the interface specification of each network element device in the business of PHS network site in succession.As the communications protocol-Le interface protocol between location service management platform (LSMC) and the location services client (Location Service Client comprises the location service application content SP of provider).Communications protocol-Ln interface protocol between location service management platform (LSMC) and the location gateway (GLC).
Interface protocol has been stipulated protocol transmission carrying employing http protocol, and message content adopts the XML form.But do not do regulation for the concrete connected mode between the network element device.
There are two kinds based on the connected mode between the interconnected network entity of ICP/IP protocol, long connected mode and short connected mode.So-called long the connection refers to can send a plurality of packets continuously on a TCP connects, and during the TCP connection keeps, if there is not packet to send, needs both sides to send out the link detecting bag to keep this connection.And short the connection is meant when communicating pair has data interaction, just sets up a TCP and connects, and after data are sent completely, then disconnect this TCP and connects.
Http protocol is the application layer protocol that is carried on the TCP/IP, is a kind of stateless agreement, and its 1.1 regulation and stipulation acquiescence adopts long connected mode, and its 1.0 regulation and stipulation acquiescence is to adopt short connected mode.
Adopt the long following advantage that is connected with:
A, reduced each establishment, closed the system resource overhead (CPU, internal memory) of connection.
B, can in a connection, send, receive a plurality of requests, save time.
C, because TCP connect to reduce, reduce network congestion.
But adopt long connected mode, system need increase the management for connection resource, need to take some system resources, and the concurrent performance of system is bad more.
Adopt short connected mode, can make and realize simply, after the intact once-through operation of each connection processing, connection closed is got final product, and can obtain reasonable concurrent performance.Shortcoming is all to want newly-built TCP to connect at every turn, causes a bit influence on performance time response.
Through retrieval, do not find that positioning service interface length connects the document and the patent of self adaptation correlation technique at present as yet.
Summary of the invention
The objective of the invention is in order to overcome the drawback that employing merely in the prior art " the long connection " mode or simple employing the " weak point connects " mode exist, the present invention proposes a kind of business interface length and connects adaptive implementation, no matter it still is " the short connection " that client is initiated " the long connection ", system can both transparent processing.User (operator) can dispose the access connected mode of SP neatly according to the environment of reality use, solves the inflexible problem of access connected mode that exists in the prior art.
Implementation method of the present invention is as follows:
The first step: positioning service interface receives Location Request there from location service application content provider;
Second step: the HTTP message header that the positioning service interface analysis receives, determine the connected mode of being asked;
The 3rd step: the connected mode authentication, whether consistently see with the connected mode that allows; If inconsistent, then directly refuse;
The 4th step: the routing self-adaption distribution, if comprise " Connection:Keep-Alive " content, then walk long connection processing mode; Otherwise walk short connection processing mode;
The 5th step: long connection processing mode is handled or short connection processing mode is handled.
Adopt business interface length to connect adaptive processing method, can allow user (operator), adopt different strategies flexibly according to the actual conditions of using.The SP of Jie Ruing is fewer if desired, can consider to adopt the access way that connects based on long.If SP is many, can adopt the access way that connects based on short.Also can adopt long connected mode by wherein a part of SP, all the other SP adopt short connected mode.Compared with prior art, need not increase new investment, just can reach the purpose that differentiation inserts, for carrying out of location-based service business provides strong assurance.

Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
Fig. 1 is a wireless network location system business interface logic diagram, as shown in the figure, SP carries by HTTP, send the locating request message of XML form to navigation system, navigation system is resolved after receiving message, then message is mail to Radio Network System, the infinite network system returns to navigation system to positioning result, by http protocol the result is returned to SP again by navigation system.
What Fig. 2 described is that business interface length connects the self adaptation realization flow, and treatment step is as follows:
The first step: that receives Location Request to positioning service interface from SP;
Second step: the HTTP message header that the positioning service interface analysis receives;
The 3rd step: the connected mode authentication, whether consistently see with the connected mode that allows; If inconsistent, then directly refuse;
The 4th step: the routing self-adaption distribution, if comprise " Connection:Keep-Alive " content, then walk long connection processing mode; Otherwise walk short connection processing mode;
The 5th step: long connection processing mode is handled or short connection processing mode is handled.
What Fig. 3 described is long connection processing flow process, and treatment step is as follows:
Step 1, from HTTP message body, isolate locating request message to be processed, do not close the bottom communication and connect.
Step 2, communication is connected handle be saved in the connection pool, generate connection identifier ID simultaneously.Connection pool is a data structure, preserves connection identifier ID and connects handle, also has other some timers etc.
Step 3, preservation user ask ID, connection identifier ID in user data area.User data area also is an internal storage data structure, the state of user information of in store current active.
Step 4, send Location Request (carrying request ID) to wireless network.
