Embodiment 1

[0064] The system of this embodiment is as figure 1 As shown, the routing service device network in the figure only represents a routing service device network, and the specific network topology depends on the specific implementation. The present invention does not involve how to perform routing service device networking, and only requires softswitch control within the roaming range All devices are added to the routing service device network.

[0065] exist figure 1 Among them, D2 is a subscriber of the softswitch control device S2. When D2 roams from S2 domain to S1 domain, it needs to register with S1. The whole registration process includes the following steps:

[0066] D2 is connected to the network, and after finding the address of the registration server G1, step 100;

[0067] D2 sends a registration request to the registration server G1, step 110;

[0068] According to the user identification in the registration request, G1 judges that D2 is not a subscriber in this ...

no. 2 example

[0078] figure 1 , when D2 returns to the contracted S2 domain from the roaming S1 domain, it needs to re-register with S2. The registration process is as follows:

[0079] D2 is connected to the network, and searches for the address of the registration server G2, step 200;

[0080] D2 sends a registration request to the registration server G2, step 210;

[0081] According to the user ID in the registration request, G2 learns that it is a subscriber of the domain S2, step 220;

[0082] G2 checks the legality of the identity information, if it is legal, registers D2, notifies S2 to allocate resources, and learns the softswitch control device S1 of its roaming place from the registration message, step 230;

[0083] G2 notifies S2 to report location update information (D2, S2) to routing server, step 240;

[0084] G2 notifies G1 through S1: "D2 has returned to the signing place", step 250;

[0085] G1 cancels the D2 information, and notifies S1 to report location update inform...

no. 3 example

[0087] figure 2 In this example, D2 roams from the roaming domain S1 to another roaming domain S3, and D2 needs to re-register with S3. Assuming that G1 contains the address information of G2 in this embodiment, the registration process is as follows:

[0088] D2 is connected to the network, and searches for the address of the registration server G3, step 300;

[0089] D2 sends a registration request to the registration server G3, step 310;

[0090] G3 judges that D2 is not a user in this domain according to the user identification in the registration request, and at first finds the original roaming place S1 of the user to the routing server, step 320;

[0091] G3 queries S1 for the address of its registration server G1, step 330;

[0092] S1 tells G3 the address of G1 and the information that D2 is its original roaming user, as well as the address of the softswitch control device S2 and the registration server G2 in its contracted place, step 340;

[0093] G3 sends the id...

Abstract

The invention discloses a method and system for realizing subscriber roaming through a route server, wherein a route server is employed into accomplish next generation cross-area network architectures, when a roaming device is switched in, the registration server performs authentication and informs the soft swapping control apparatus for registration operation and location refreshing message submitting. For the roaming subscriber related services, the soft swapping control apparatus can accomplish switching and control through the conventional procedures.

Description

technical field [0001] The invention relates to a broadband communication network, in particular to a method and system for roaming in different places under the network architecture. Background technique [0002] The current communication methods are mainly divided into wired communication and wireless communication according to the access method. The user terminal equipment in the wired network is usually bound together with physical lines such as cables, and the relationship between them is one-to-one. If the user migrates to another place, the operator needs to provide the relocation service instead of enjoying the Anytime, anywhere service. In the wireless network, wireless communication systems such as GSM and CDMA inherently provide remote roaming services due to the fact that wireless access does not have the trouble of physical lines, and its realization relies on VLR / HLR and other equipment to realize roaming services. [0003] Due to more and more exchanges, tel...
