Abstract
The invention provides a method and system for remotely accessing. A mobility management device receives a remote access requesting message sent by User Equipment (UE), determines whether the UE possesses right for accessing a home network under the control of a home base station according to contents in the remote access requesting message, when determining the UE possesses the right, selects a GateWay (GW) device. Technical scheme of the invention enables a subscriber to remotely access a home network, even if the subscriber is not in the home network.
Claims12
A method for remotely accessing a home network, comprising:
- receiving, by a mobility management device, a remote access requesting message sent by User Equipment (UE), wherein the remote access requesting message comprises UE identifier, type identifier of a service for remotely accessing a home network and identifier of a home base station;
- querying, by the mobility management device, according to contents in the remote access requesting message, to determine whether the UE possesses right for accessing the home network under the control of the home base station, when determining the UE possesses the right, selecting, by the mobility management device, a GateWay (GW) device, and sending the contents in the remote access requesting message to the GW device;
- or
- selecting a GW device by the mobility management device firstly, sending the contents in the remote access requesting message to the GW device, wherein whether the UE possesses the right for accessing the home network under the control of the home base station currently accessed by the UE is determined by the GW device,
- wherein when determining whether the UE possesses the right for accessing the home network under the control of the home base station, a scope of an available IP address for the home network under the control of the home base station is obtained from an Access Control List (ACL) server according to the identifier of the home base station, and an IP address for the UE is allocated according to the scope of the available IP address by the GW device.
A method for registering an available IP address in a home network in, the method comprising:
- establishing, by a home base station, a secure tunnel with a security GateWay (GW), after the home base station starting up and initializing;
- and
- reporting, by the home base station, an IP address allocated for the home base station and a scope of the available IP address to an Operation Administration Maintenance (OAM) server,
- wherein the IP address allocated for the home base station is allocated after authenticating the home base station successfully, the scope of the available IP address is provided by the security GW, and the IP address allocated for the home base station and IP address in the scope of the available IP address belong to one address pool,
- wherein the IP address of the home base station and the scope of the available IP address is reported to an Access Control List (ACL), server by the OAM server.
A method for remotely accessing a home network, the method comprising:
- receiving, by a Gate Way (GW) device, contents in a remote access requesting message from a mobility management device, wherein the remote access requesting message is sent by User Equipment (UE) and comprises UE identifier, type identifier of a service for remotely accessing a home network and identifier of a home base station;
- determining, by the GW device, whether the UE possesses right for accessing the home network under the control of the home base station currently accessed by the UE;
- when determining the UE possesses the right for accessing the home network under the control of the home base station, searching in an Access Control List (ACL) server by the GW device according to the identifier of the home base station, to obtain a scope of an available IP address for the home network under the control of the home base station, and allocating an IP address for the UE according to the scope of the available IP address;
- and
- sending, by the GW device, the allocated IP address to the UE, to enable the UE to remotely access the home network under the control of the home base station according to the allocated IP address.
