Abstract
A wireless network including a wireless access gateway (WAG) and methods are provided for routing traffic between non-cellular and cellular networks. The WAG interconnects at least one non-cellular network and at least one cellular network in an at least one-to-many relationship. The WAG receives a first IP address for the UE in the cellular domain and the WAG allocates a second IP address for the UE in the non-cellular domain. The WAG creates a routing rule including the first and second IP addresses for the UE and an additional data path identifier.
Claims22
A method of controlling a wireless access gateway (WAG), the WAG interconnecting at least one non-cellular network and at least one cellular network in an at least one-to-many relationship, wherein each non-cellular network allocates IP addresses for use across a domain of the respective non-cellular network and each cellular network allocates IP addresses for use across a domain of the respective cellular network, the method comprising:
- a WAG receiving a first IP address for a User Equipment (UE) from a first cellular network, the first IP address being allocated by the first cellular network for use across the domain of the first cellular network;
- the WAG allocating a second IP address for the UE and sending the second IP address to a first non-cellular network, the second IP address being different from the first IP address and being for use across the domain of the first non-cellular network;
- and
- the WAG translating between the first and second IP addresses for the UE and based on a data path identifier, wherein the data path identifier uniquely identifies a data path between the UE and the cellular network.
A device adapted to interconnect at least one non-cellular network and at least one cellular network in an at least one-to-many relationship, wherein each non-cellular network allocates IP addresses for use across a domain of the respective non-cellular network and each cellular network allocates IP addresses for use across a domain of the respective cellular network, the device comprising:
- a communications interface adapted to receive a first IP address for a User Equipment (UE) from a first cellular network, the first IP address being allocated by the first cellular network for use across the domain of the first cellular network;
- and
- a processor adapted to allocate a second IP address for the UE, the second IP address being different from the first IP address and being for use across the domain of the first non-cellular network,
- wherein the communications interface is further adapted to send the second IP address to the first non-cellular network, and the processor is further adapted to create a translation rule to translate between the first and second IP addresses for the UE based on a data path identifier, wherein the data path identifier uniquely identifies a data path between the UE and the cellular network.

- a processor adapted to allocate a second IP address for the UE, the second IP address being different from the first IP address and being for use across the domain of the first non-cellular network,
- wherein the communications interface is further adapted to send the second IP address to the first non-cellular network, and the processor is further adapted to create a translation rule to translate between the first and second IP addresses for the UE based on a data path identifier, wherein the data path identifier uniquely identifies a data path between the UE and the cellular network.
