Signalling method for communication networks, corresponding network, devices and computer program product
First Claim
1. A method comprising:
- implementing a signalling mechanism between an Access Service Network and a Connectivity Service Network in a communication network;
signalling a status of a mobility binding procedure between a Mobile Station and a Home Agent in said communication network with said signalling mechanism,said status including Binding Update and Binding Acknowledgement status; and
allowing the Connectivity Service Network to send specific signalling messages to an Access Service Network Gateway to inform said Access Service Network Gateway of the status of the mobility binding procedure, and to allow said Access Service Network Gateway to avoid parsing each U-plane message between said Mobile Station and said Home Agent to obtain said status of said mobility binding procedure.

Abstract
A method is proposed, for use e.g. in the context of WiMAX networks supporting the CMIPv6 function, for allowing the ASN-GW to become aware of the status of a control procedure, the CMIPv6 mobility binding procedure. The ASN-GW is not directly aware of its result since the procedure implies a message exchange at the U-Plane level, where the ASN-GW implements only a routing function. Nevertheless the ASN-GW needs to know the status of the procedure since it has to perform some subsequent actions depending on that status. The method includes signalling the status via a signalling mechanism between the Access Service Network and the Connectivity Service Network, thus avoiding packet inspection at the U-plane by the Access Service Network Gateway.

8. A computer program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising code for performing the following:
-
implementing a signalling mechanism between an Access Service Network and a Connectivity Service Network in a communication network; signalling a status of a mobility binding procedure between a Mobile Station and a Home Agent in said communication network with said signalling mechanism, said status including Binding Update and Binding Acknowledgement status; and allowing the Connectivity Service Network to send specific signalling messages to an Access Service Network Gateway to inform said Access Service Network Gateway of the status of the mobility binding procedure, and to allow said Access Service Network Gateway to avoid parsing each U-plane message between said Mobile Station and said Home Agent to obtain said status of said mobility binding procedure.

9. An apparatus comprising:
-
one or more processors; and one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the apparatus to perform at least the following; implementing a signalling mechanism between an Access Service Network and a Connectivity Service Network in a communication network; signalling a status of a mobility binding procedure between a Mobile Station and a Home Agent in said communication network with said signalling mechanism, said status including Binding Update and Binding Acknowledgement status; and allowing the Connectivity Service Network to send specific signalling messages to an Access Service Network Gateway to inform said Access Service Network Gateway of the status of the mobility binding procedure, and to allow said Access Service Network Gateway to avoid parsing each U-plane message between said Mobile Station and said Home Agent to obtain said status of said mobility binding procedure.
