摘要
Provided are a communication network implemented based on a control-plane-and-medium-plane-splitting network architecture, a method for accessing a corresponding communication network by a terminal and a disposal method for off-line terminals. The communication network includes a wireless access network, an access node, a mobility managing node, an identity location register (ILR) and a packet data network. The access node provides access service for the terminal, allocates a routing identifier (RID) pointing to the present access node, maintains mapping information between the terminal and opposite communication end and performs registration, deregistration and query for the terminal RID at the home location ILR of the terminal, thereby implementing routing and forwarding the data packet; the ILR receives a request for registering and deregistering the home user terminal of the present ILR, maintains access identifier (AID)-RID mapping information of the home user terminal, and returns the RID corresponding to the terminal AID included in a query request to the query requestor after receiving the request for the terminal RID. The invention can avoid route bypass without changing the application scene of the terminal.
