Abstract
The embodiment of the invention discloses a method for determining the user state, a device and a system therefor, belonging to the communication field. The method, the device and the system are invented for solving the problem that the home location register can not judge whether the user data is deleted or not in the prior art, therefore, the follow-up invalid flow is generated. The embodiment of the invention provides the technical proposal that the response message used for providing the user information and sent by a visitor location register for a called subscriber is received; and the fact that whether the deleted state mark of the called subscriber is set or not is judged according to the fact whether the enumeration value is included in the response message for providing the user information or not. According to the technical proposal provided by the embodiment, the home location register can judge whether the user data in the visitor location register is deleted or not according to the response message used for providing the user information and sent by the visitor location register, thus avoiding the follow-up invalid flow, reducing the network signaling flow, and reducing the burden of the device.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of methods, devices and systems of definite User Status.
Background technology
When VLR Visitor Location Register (VLR) finds that a certain user in its database does not have activity for a long time, VLR can delete the data of this user in its database, and initiation Purge (deletion) request message, this user's data of notice attaching position register (HLR) has not been present in the middle of this VLR, then HLR will write down this user's Purge Status Flag, and this process is called the MAP_PURGE_MS flow process.When network the user of Purge is called out and to get route, short message when getting operation such as route, just can judge this user by Purge by HLR, thereby save the generation of follow-up invalid flow process, minimizing network signal flow and facility load.
When a certain user alternately surfs the Net in two (or more than two) different VLR, to frequently initiate more new technological process of position, for reducing the network signal flow in this process, can use the Super-Charger characteristic, be the user when a VLR roams into another VLR, HLR will be not initiate the canceling position request message to the VLR at place before the user, when the user comes back to this VLR belonging network, can directly utilize the original user data of this VLR, can remove the flow process of inserting user data again from, thereby reach the purpose that reduces signaling traffic.When HLR and VLR support Super-Charger characteristic, VLR is when the deletion user data, because VLR can not determine that this user whether just in other VLR belonging networks online, does not therefore initiate the MAP_PURGE_MS flow process and gives HLR.
The customization of supporting mobile network's enhanced logic to contracting is used (CAMEL) professional user B and is made a call when getting the route flow process, and the HLR of user B at first can receive and not carry MAP_SEND_ROUTING_INFORMATION (route is got in the calling) request message that the CAMEL inhibition identifies.HLR sends MAP_PROVIDE_SUBSCRIBER_INFO (user profile is provided) request message to the VLR that this user roams the position, waits to receive that responding the back returns the MAP_SEND_ROUTING_INFORMATION response message to calling subscriber A place MSC.
After the MSC at calling subscriber A place receives the MAP_SEND_ROUTING_INFORMATION response message, can send to HLR once more and carry the MAP_SEND_ROUTING_INFORMATION request message that CAMEL suppresses sign, HLR receives this message, beginning sends MAP_PROVIDE_ROAMING_NUMBER (getting roaming number) message to the VLR of user B roaming position, finishes the remaining calling flow process that sends routing information then.
In the network of supporting the Super-Charger function, after deleting user data, VLR can not initiate the MAP_PURGE_MS flow process to HLR.After HLR receives the MAP_SEND_ROUTING_INFORMATION request message, to the MAP_PROVIDE_SUBSCRIBER_INFO request message of VLR initiation to this user, VLR can return error response message to HLR, this error response message carries error code, but can not illustrate be since user data on VLR deleted just lead to errors the sign indicating number generation, HLR will can not upgrade the Purge Status Flag of user B.So, other calling subscribers send routing information when operation when making a call to user B once more, HLR can send MAP_PROVIDE_SUBSCRIBER_INFO or MAP_PROVIDE_ROAMING_NUMBER request message to the VLR of user B roaming position once more, continue invalid follow-up flow process, the waste Internet resources.
