Abstract: A wireless communication network aligns gateways for wireless user devices. A mobility controller detects attachment of a wireless user device in a source Tracking Area (TA). The mobility manager transfers a message to a policy engine indicating the source TA. The wireless user device exchanges user data over a source access gateway and a source network gateway in the source TA. The mobility controller detects a handover of the wireless user device from the source access gateway to a target access gateway in a target TA. The mobility manager transfers a message to the policy engine indicating the target TA for the wireless user device. The policy engine transfers a reattach message to the source network gateway for delivery to the wireless user device. The wireless user device reattaches in the target TA and exchanges additional user data over the target access gateway and the target network gateway.

Abstract: 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.

Abstract: Examples disclosed herein provide systems, methods, and software for managing service modification requests in a serving gateway. In one example, a method of operating a serving gateway includes identifying an incoming service modification from a packet data network gateway and determining whether the incoming service modification is permitted based on policy data. The method further includes, if the incoming service modification is permitted, allowing the incoming service modification to proceed across the Long-Term Evolution network. The method also provides, if the incoming service modification is not permitted, altering the incoming the incoming service modification based on the policy data.

Abstract: In a communication system, a session control server receives a session request for User Equipment (UE) over a first network and exchanges signaling with the UE and a transfer control server to establish a media session. The transfer control server sends an association of the UE and the transfer control server to a translation server. The translation server associates the UE with the transfer control server. The translation server receives a transfer request for the UE from a second network and identifies the transfer control server associated with the UE. The translation server transfers the transfer request for delivery to the transfer control server. The transfer control server exchanges signaling with the second network responsive to the transfer request to transfer the media session for the UE from the first network to the second network.

Abstract: A wireless access point supports media conferencing for wireless User Equipment (UE). The wireless access point wirelessly exchanges timing signaling with the wireless UE to synchronize the wireless UE. After the wireless UE is synchronized, the wireless access point wirelessly exchanges connect signaling with the wireless UE to receive an Establishment Cause and a Wireless Network Identifier from the wireless UE. The wireless access point selects a media conferencing Mobility Management Entity (MME) when the Establishment Cause is associated with the media conferencing MME. The wireless access point selects a data MME based on the Wireless Network Identifier when the Establishment Cause is not associated with the media conferencing MME. The wireless access point exchanges network signaling with the data MME or the media conferencing MME. The wireless access point wirelessly exchanges user data with the wireless UE under control of the data MME or the media conferencing MME.

Abstract: Methods and systems are provided for identifying, to an external device, a client device having an external IP address assigned by a Network Address Translation (NAT) device. Initially, the NAT device provides an external IP address assigned to a client device to access an external device. Upon the client device communicating with the external device, the NAT device also provides an internal IP address assigned to the client device in an option field of the external IP address. If the external device later requests to communicate with the client device, and includes in the request the internal IP address in the option field of the external IP address assigned to the client device, the NAT device checks for sessions mapping to the client device. Upon determining there are no sessions mapped to the client device, a new connection is opened to the client device utilizing the internal IP address.

Abstract: A User Equipment (UE) registers with a Long Term Evolution (LTE) network. The UE registers with an Internet Multimedia Subsystem (IMS) over the LTE network. The UE registers with a Wireless Fidelity (WIF) network. The UE receives a status request from the LTE network responsive to a Session Initiation Protocol (SIP) invite for the UE received at the IMS. The UE transfers a status response to the LTE network that indicates the WIFI network responsive to the status request. The UE receives the SIP invite from the IMS over the WIFI network. The UE exchanges user data for the media session over the WIFI network.

Abstract: A wireless network receives a registration from a wireless device. The network identifies an Extensible Mark-up Language Configuration Access Protocol (XCAP) service and establishes an XCAP bearer for the wireless device. The network receives an enabling instruction over the XCAP bearer to enable the mobile data service and establishes a mobile data bearer for the wireless device. The network exchanges user data with the wireless device over the mobile data bearer. The network automatically establishes the mobile data bearer for the wireless device responsive to subsequent registrations when the mobile data service is enabled. The network receives a disabling instruction over the XCAP bearer to disable the mobile data service for the wireless device. The network terminates the mobile data bearer for the wireless device and does not automatically establish the mobile data bearer for the wireless device responsive to subsequent registrations when the mobile data service is disabled.
