Embodiment Construction

[0036] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0037] The present invention will reuse the P-Access-Network-Info header field to describe the geographical access point of users accessing through the fixed network, so that the fixed access terminals accessing the core network of packet telecommunications using SIP as call control signaling The user can use the access geographic point carried in the header field to accurately query the geographical location information such as the nearest emergency call center to the user or the time zone where the user is located. It should be noted that the newly added description of the header field in this embodiment is only to highlight the parameter information it must carry, and it does not mean that this is the only way of description.

[0038] In this embodiment, an access type field (access-type) needs to be added in the P-Access-Network-Info ...

Abstract

A method for querying geographical position information of packet domain includes launching logon or call by fixed access terminal and setting access type field and access information field in P-Access-Network-Info head domain of SIP message in said logon or call, judging geographical position information of terminal to be queried according to said call or attribute of varied service data when SIP message of call or request to very service data of terminal user is received by network service node, picking up said access information from SIP message and sending said access information as parameter of query message to geographical position information databank.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for querying geographic location information in a packet domain. Background technique [0002] The geographic location information query service is a basic telecommunication service, and the packet domain telecommunication network currently under development must also support it. Including wake-up services with time element requirements, scheduled calls, schedule reminders, scheduled conferences, etc., need to trigger related services according to the time set by the user. It also includes emergency call services with space elements, etc. We take emergency business as an example, and other businesses are similar. [0003] In the application of emergency services, it is a key issue to query the emergency call center (ECC Emergency Call Center) closest to the calling user who initiated the emergency call. Usually, there are two ways to realize this query: [0004] 1) The acces...
