System and method of network access security policy management for multimodal device
First Claim
1. A system for network access security policy management of multimodal access to a converged network, the system comprising:
- an inter-technology change-off monitoring entity (ICME) for detecting an inter-technology change-off of a multimodal device from a first access technology to a second access technology, and for transmitting an inter-technology change-off message;
a policy database for storing a plurality of access technology policies; and
a policy manager for receiving said inter-technology change-off message from the ICME, for searching said policy database for an access technology policy corresponding to said second access technology, for determining appropriate policies to be enforced, and for distributing said appropriate policies to at least one policy enforcement point (PEF) for enforcing said appropriate policies in respect of access by the multimodal device to the converged network.

Abstract
A system and method are provided for management of access security for access by a multimodal device to a converged fixed/mobile network. An inter-technology change-off monitoring entity (ICME) is provided to monitor an inter-technology change-off of the multimodal device and to notify a policy manager of the inter-technology change-off. The policy manager looks up in a policy database, security policies applicable to the user of the multimodal device and the particular technology being used by the multimodal device. The policy manager conveys to various policy enforcement points throughout the converged fixed/mobile network the applicable security policies which take into account the user'"'"'s identity and the access technology being used.

10. A method for network access security policy management of multimodal access to a converged network, the method comprising:
-
detecting at an inter-technology change-off monitoring entity (ICME) occurrence of an inter-technology change-off of a multimodal device from a first access technology to a second access technology; transmitting an inter-technology change-off message from said inter-technology change-off monitoring entity (ICME) to a policy manager; searching a policy database by said policy manager for an access technology policy corresponding to said second access technology; determining at the policy manager appropriate policies to be enforced; distributing from said policy manager to at least one policy enforcement point (PEF) said appropriate policies; and enforcing said appropriate policies at said at least one PEF in respect of access by the multimodal device to the converged network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
