A wireless network of a first type receives a request for network entry from a mobile station. A service continuity query is sent to a service node. A service continuity response is received from the service node. The service continuity response includes a network access identifier. The network access identifier is determined to be associated with an existing session on a wireless network of a second type. The existing session is using a mobile internet protocol address. On the wireless network of the first type, a session is assigned the mobile internet protocol address.

Cross-technology session continuity

In a Long Term Evolution (LTE) network, an LTE gateway system exchanges registration data with User Equipment (UE) over a non-LTE network. The LTE gateway system transfers networking data to an LTE control system responsive to an IMS media session for the UE, and transfers an instruction to remove the networking data from the LTE control system responsive to termination of the IMS media session. The LTE control system receives an LTE initial access message and if the networking data characterizes the IMS media session over the non-LTE network through the LTE gateway system, then transfers a session transfer message to the LTE gateway system to switch communication access from the non-LTE network to the LTE network. The LTE control system receives an LTE session termination message and responsively transfers an LTE reattach message to the LTE gateway system to force the UE to reattach to the LTE network.

Long term evolution (LTE) communication system to transfer communications from non-LTE to LTE networks

What is disclosed is a method of operating a communication system, where a user device receives wireless access for a communication session over a first wireless communication network. The method includes receiving a registration request transferred by the user device for wireless access from a second wireless communication network, and in response to the registration request, processing an authentication status for the communication session of the first wireless communication network to authenticate the communication session in the second wireless communication network.

Selective authentication of user devices in wireless communication networks

Embodiments disclosed herein provide systems and methods for selectively discarding Diameter protocol messages in an LTE communication system. In a particular embodiment, a method provides receiving a plurality of Diameter protocol messages at the communication control system and determining a measure of Diameter message congestion. If the measure of Diameter message congestion satisfies a congestion criteria, the method provides determining a priority of at least one message of the plurality of Diameter protocol messages. Messages associated with communication sessions participating in a data session have higher priority than messages associated with communication sessions currently establishing and the messages associated with communication sessions currently establishing have higher priority than messages associated with initiating communication sessions. The method further provides selectively discarding the at least one message based on the priority of the at least one message relative to priorities of other messages of the plurality of Diameter protocol messages.

Selective discard of diameter protocol messages

An authorization system in a home wireless network comprises a communication interface and a processing system, wherein a wireless communication device associated with the home wireless network transfers a network service request to a service node to acquire a static packet address for the wireless communication device. The communication interface is configured to receive an authorization request for the wireless communication device, transfer a query for delivery to a user profile system, receive a packet address of a home agent associated with the wireless communication device, transfer an authorization response, and receive an authentication request transferred from the home agent. The processing system is configured to process the authentication request to determine the static packet address for the wireless communication device. The communication interface is configured to transfer an authentication response for delivery to the home agent, wherein the authentication response includes the static packet address for the wireless communication device.
