摘要:
A method for connection roaming a Mobile Node (MN) to a Network GateWay (NGW) for providing secure data path using Internet Protocol (IP) security procedure. Also Mobile IP (MIP) is required for providing mobility to the user, when the MN moves from one sub-network to another. However, when the Home Address of the network is not known, a cyclic interdependency is observed between the IP Security (Ipsec) procedures and MIP procedures. If the home address of the MN is not known initially during the procedure, IPsec Security Associations (SA's) are formed between the MN and NGW such that only MIP packets are passed through. After the MIP Registration is completed, the Home Address of the MN is known from the MIP registration Reply. MN now forms a data path tunnel with the NGW by exchanging Create_Child_SA messages.

Disclosed is an apparatus and a method for allocating persistent resources in order to support a packet service in a mobile communication system. The method includes acquiring scheduling information including an allocation period of a persistent resource corresponding to a predetermined packet state in a process of call setup between the communication apparatus and the Node B; receiving an allocation period and a size of a persistent resource to be allocated based on the packet state; and receiving a packet through the allocated persistent resource.

Disclosed is a method and system of deriving new keys for accessing a new system. The method enables an optimized authentication procedure during handover form an existing system to a new system by using the existing system access keys. The user equipment that is accessing the new system receives a temporary ID during handover preparation which enables the user equipment to perform a fast re-authentication. The method uses existing system access keys to derive system access keys for the new network.
