Problems solved by technology

[0005] However, the existing OSA technology cannot realize the opening of these PDP CONTEXTS attribute network capabilities. Currently, devices within the network can directly access the home location register HLR to obtain this information, but cannot open it to applications.
Therefore, the application server cannot use these network capabilities to implement services, which limits the scope of the application server's business

Embodiment Construction

[0013] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0014] System structure of the present invention and relevant interactive process schematic diagram are respectively shown in figure 1 , 2 , the query method of the packet data protocol context attribute expressed by it includes the following steps:

[0015] 1) The application party APPLICATION invokes the application programming interface QUERYPDPS API for querying the packet data protocol context attribute PDP CONTEXTS to the service capability server SCS, and uses the user's mobile phone number to specify the user;

[0016] 2) The service capability server SCS sends a message to the home location register HLR to query the user's packet data protocol context attribute PDP CONTEXTS attribute; this message belongs to internal signaling and is determined by each equipment manufacturer.

[0017] 3) The home location register H...

Abstract

The present invention discloses an inquiry method of block protocol context attribute and its system. Said metho dincludes the following steps: the application side calls the applied programming interface for inquiring block data protocol context attribute from service power server; using user's handset number code to show clearly user; the service power server can transmit a message for inquiring user's block data protocol context attribute to attaching position register; the attaching position register can feed back the response message; returning the result into applicatino side by servicepower server; and then completing the calling of applied programming interface. Said invention can implement opening of PDP CONTEXTS network capacity, so that the server can utilize these network capacity to implement various services of GPRS terminal user.

Description

Technical field: [0001] The invention relates to a query method and system for packet data protocol context attributes (namely PDP CONTEXTS). Background technique: [0002] In the future, users will have more and more demands on services and require faster and faster service provision. In order to provide services quickly and effectively, it is necessary to provide third parties (application parties, or application servers, APPLICATION for short) with network-capable interfaces. As a result, the 3GPP standardization organization launched an open service access (OSA) architecture to provide an open interface to network capabilities. The implementation method is as follows: Service Capability Feature Sets (SCFs) representing network capabilities provide an open interface of OSA through a service capability server (SCS), and service developers use different SCFs through service development tools to realize services. For OSA, the core entity is the SCS. [0003] OSA adopts obj...
