Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of methods, devices and systems of judging roaming location of mobile communication equipment.
Background technology
For the mobile communication equipment services of roaming, mobile operator will take different charging policy according to the roaming agreement of signature according to the difference of roaming location of mobile communication equipment.In WCDMA (Wideband Code Division Multiple Access (WCDMA)) network, user's charging is gone up realization at GGSN (Gateway GPRS Support Node), so just need on GGSN, can get access to user's the roaming place network information.
In the WCDMA network, mobile communication equipment activates on GGSN by SGSN (Serving GPRS Support Node), and GGSN distributes the address for mobile communication equipment and the service of accesses network is provided.When mobile communication equipment when its local carrier network is inner, connect the activation mobile communication equipment by the SGSN in the local network and GGSN; When mobile communication equipment roams in the network of other operators, set up GTP (GPRS Tunnel Protocol) by SGSN in other carrier networks and local GGSN and be connected and activate.At present, mainly judge the roaming place information of mobile communication equipment by following dual mode:
One, use the RAI/ULI attribute in the GTP message that SGSN carries up to judge roaming location of mobile communication equipment.But because RAI/ULI is the non-essential attribute of GTP agreement regulation, therefore might not appear in the GTP message, can't guarantee that the SGSN of all roaming places can carry RAI or ULI.
Two, use SGSN IP to identify (differentiation) roaming location of mobile communication equipment, on GGSN, set up and safeguard the mapping table of SGSN IP and roaming place operator by configuration mode.But the roaming partner of signature can get more and more, and SGSN IP also can get more and more thereupon; And because network change, SGSN IP also may change.Based on this 2 point, the mapping table by configuration mode manual maintenance SGSN IP and roaming place operator on GGSN is very difficult, and is difficult to satisfy because the real-time update requirement of network change.
Therefore, adopt existing roaming location of mobile communication equipment judgment technology, exist applicability wideless, the problem that real-time and accuracy are not high.

Embodiment
Wideless in order to solve existing roaming location of mobile communication equipment judgment technology applicability, the problem that real-time and accuracy are not high.The embodiment of the invention provides a kind of method of judging roaming location of mobile communication equipment.
As shown in Figure 1, the method for the judgement roaming location of mobile communication equipment that the embodiment of the invention provides comprises:
101, obtain the IP address of the Serving GPRS Support Node SGSN of roaming location of mobile communication equipment;
When mobile communication equipment carries out talk business in the roaming place, need elder generation on the GGSN of this locality, to activate by the SGSN of roaming place, and be after mobile communication equipment distributes the address by GGSN, mobile communication equipment just can be conversed, when GGSN receives the active information that roaming place SGSN sends, the IP address that obtains roaming place SGSN according to the source address of described active information;
102,, obtain the autonomous system number of described SGSN place network according to described IP address;
103,, determine the roaming place of mobile communication equipment according to the corresponding relation between autonomous system of setting up in advance number and the roaming place.
The mobile communications network of each operator all is made up of one or several autonomous systems, each autonomous system can be distributed an autonomous system number unitedly by the whole world, the described autonomous system whole world is unique, and, therefore can utilize autonomous system number to identify the roaming place of mobile communication equipment in case can not change substantially after distributing.
As shown in Figure 2, according to described IP address, the step of obtaining the autonomous system number of described SGSN place network comprises:
201,, obtain BGP (Border Gateway Protocol) routing iinformation of SGSN place, roaming place network according to described IP address;
Intercom mutually by operation BGP Routing Protocol between the different networks; After local GGSN has obtained the IP address of roaming place SGSN, in the routing table of self, find the route of its coupling, be SGSN place, roaming place network B GP routing iinformation according to described IP address;
202, obtain the autonomous system number of SGSN place network according to described routing iinformation.
Write down in the AS_Path attribute in the network B GP routing iinformation of place, roaming place from roaming place SGSN to local GGSN by way of all autonomous systems number; From described AS_Path attribute, obtain the autonomous system number of roaming place belonging network correspondence.
As shown in Figure 3, suppose that roaming place SGSN is positioned at autonomous system AS10, local GGSN is positioned at autonomous system AS50.
When network carries out initialization, operation BGP Routing Protocol, D=8.0.0.0 is communicated to other AS with network segment route, at first the AS of AS10 numbering 10 is put into (10) in the AS_Path attribute; Through behind the AS20, AS20 numbers own AS 20 Far Lefts (20,10) that are put into the AS_Path attribute again, by that analogy.
When the GGSN in the AS50 obtains this route, just can know according to the AS_Path attribute, arriving the AS path that the address of this network segment of 8.0.0.0 need pass through is (30,20,10), AS according to last process is numbered 10, and the AS numbering that can judge 8.0.0.0 network segment place network is 10.
Set up the corresponding relation of autonomous system number and roaming place information in advance, because the autonomous system whole world is unique, each operator only uses limited several autonomous systems number of distributing to oneself separately, and in case the characteristic that can not change substantially after distributing, therefore described corresponding relation relative fixed and clauses and subclauses are limited, safeguard also comparatively simple.
After the autonomous system that obtains roaming place belonging network correspondence number, can inquire roaming place information according to the corresponding relation of being set up, thereby take corresponding charging policy.
In concrete enforcement, the embodiment of the invention provides two kinds of specific implementations, is described respectively below:
One, corresponding relation is disposed among the GGSN, GGSN inquires corresponding roaming place information after obtaining autonomous system number, then described roaming place information is sent to counting equipment, takes corresponding charging policy by counting equipment.
Two, corresponding relation is disposed in the counting equipment, after GGSN obtains autonomous system number, described autonomous system number is sent to counting equipment, number in corresponding relation, obtain roaming place information by counting equipment according to described autonomous system, and take corresponding charging policy according to roaming agreement.
