US 8,274,982 B2 · Method for packet data session release in ultra mobile broadband access network

Abstract

A packet data session release method for ultra mobile broadband access network is disclosed, and which includes: S402, when releasing the packet data session, an access gateway sends a proxy mobile IP registration revocation message to the data attachment point of the ultra mobile broadband access network and the evolved base station which has one reverse proxy mobile IP tunnel to the access gateway, respectively; S404, after receiving the proxy mobile IP registration revocation message, the data attachment point and the evolved base station which has one reverse proxy mobile IP tunnel to the access gateway, delete their proxy mobile IP tunnels between them and the access gateway, respectively, and send a proxy mobile IP revocation ACK message to the access gateway, respectively, so as to confirm the reception of the registration request messages; and S406, the data attachment point notifies the session reference network controller that the packet data session has been released, via sending a IP tunnel notification message to the session reference network controller.

Dependent claims

A method for packet data session release in ultra mobile broadband (UMB) access network, comprising the following steps:

when releasing the packet data session, sending, by an access gateway (AGW), a proxy mobile IP (PMIP) registration revocation message to a data attachment point of the UMB access network;
after receiving the PMIP registration revocation message, sending, by the data attachment point, a PMIP revocation ACK message to the AGW to confirm the reception of the PMIP registration revocation 1 message;
sending, by the data attachment point, an IP tunnel notification message to a session reference network controller (SRNC) to notify the SRNC that the packet data session has been released;
performing, by the SRNC and after receiving the IP tunnel notification message, sending an IP tunnel notification ACK message to the data attachment point to confirm that the SRNC has received the IP tunnel notification message, triggering a UMB session release, and sending a session release message to the route set members of the AT and the data attachment point;
and
after receiving the session release message, sending, by the route set members and the data attachment point respectively, a session release ACK message to the SRNC to confirm that the route set members and the data attachment point have received the session release message.

when releasing the packet data session, sending, by an access gateway AGW, a PMIP registration revocation message respectively to a data attachment point of the UMB access network and an eBS which has a reverse PMIP tunnel to the AGW;
performing, after receiving the PMIP registration revocation message, by the data attachment point and the eBS, deleting the PMIP tunnels between them and the AGW respectively, and sending a PMIP registration revocation acknowledge message to the AGW respectively, so as to confirm that they have received a PMIP registration revocation message;
and
informing, by the data attachment point, the SRNC that the packet data session has been released, through sending an IP tunnel notification message to the SRNC.
