Abstract: A wireless access point is linked to multiple wireless network cores. The wireless access point wirelessly transmits a multi-role wireless network identifier for a multi-role network. The wireless access point wirelessly receives device attachment signaling indicating a device role from the wireless user device responsive to the multi-role wireless network identifier. The wireless access point processes the device role to select the optimal one of the wireless network cores from the multiple wireless network cores. The wireless access point transfers network attachment signaling for the wireless user device to the selected and optimal wireless network core.

Abstract: A data communication gateway. The gateway comprises a processor, a non-transitory memory, and an application stored in the non-transitory memory. When executed by the processor, the application receives a secure socket layer (SSL) client hello message identifying a server and an application layer communication protocol from a client executing on one of a user equipment (UE), a laptop computer, a notebook computer, a tablet computer, or a desktop computer and determines to deny an application layer communication service access of the client to the identified server. In response to determining to deny service access, sending a SSL server hello message comprising a client redirection extension to the client that identifies a web server configured to provide a courtesy message associated with the service denial in response to a hypertext transfer protocol (HTTP) GET message or a secure hypertext transfer protocol (HTTPS) GET message.

Abstract: An Internet Multimedia Subsystem (IMS) identifies a Long Term Evolution (LTE) network serving the UE. The IMS receives a Session Initiation Protocol (SIP) Invite message for the media session to the UE and responsively transfers a status request for delivery to the LTE network serving the UE. The LTE network identifies a status of an LTE base station serving the UE and identifying an alternative communication network serving the UE. The LTE network determines that the media session should be redirected to the alternative communication network based on the status of the LTE base station and the identified alternative communication network serving the UE. The LTE network transfers a status response for delivery to the IMS indicating media session redirection to the alternative communication network. The IMS then transfers the SIP Invite message for the media session to the UE for delivery to the alternative communication network serving the UE.

Abstract: A wireless communication system connects User Equipment (UE) to Mobility Management Entities (MMEs). The wireless communication system receives a connection message from the UE. The wireless communication system connects the UE to a first MME responsive to the connection message. The wireless communication system performs MME re-selection for the UE responsive to the connection message. The wireless communication system connects the UE to a second MME responsive to the MME re-selection.

Abstract: A mobility server receives a tracking area update from User Equipment (UE) indicating UE Identifier (ID) and current tracking area ID and responsively determines if the current tracking area ID is new tracking area ID. If current tracking area ID comprises new tracking area ID, then the mobility server updates a tracking area database with new tracking area ID. The mobility server translates UE ID and current tracking area ID into candidate Access Point Name (APN) data set and determines if candidate APN data set is a new APN data set. If candidate APN data set comprises new APN data set, then the mobility server transfers an instruction for UE to perform a wireless reattachment to obtain candidate APN data set and receives an attachment request from UE indicating UE ID and current tracking area ID and responsively transfers candidate APN data set to a data network gateway.

Abstract: In an LTE network, an MME processes network status information to transfer aggregated data to an ANDSF. The ANDSF processes a request from a wireless communication device that indicates device location and the aggregated data to generate an information response indicating a priority between the LTE network and a non-LTE network at the device location. The ANDSF transfers the information response for delivery to the wireless communication device. The wireless communication device processes the information response to select between the LTE network and a non-LTE network at the device location.

Abstract: A wireless communication network controls idle-mode handovers for User Equipment (UE). A network controller receives a Tracking Area Update (TAU) from the UE that indicates an idle-mode handover from a source Tracking Area (TA) to a target TA and transfers an authorization request indicating the target TA. An authorization database processes the authorization request to authorize the UE to use the target TA and returns a TA authorization result. When the authorization result is positive, the network controller transfers a create bearer message for the UE to a network gateway. When the authorization result is negative, the network controller transfers a TAU rejection to the UE without transferring the create session message to the network gateway. The TAU may indicate a target Public Land Mobile Network (PLMN), and the authorization database authorizes the UE to use the target PLMN to authorize the UE to use the target TA.

Abstract: A mobility management entity (MME) in a data communication system to facilitate reselection of optimal network elements for a wireless communication device traversing MME regional boundaries comprises a communication transceiver and a processing system. The communication transceiver is configured to receive a context transfer associated with the wireless communication device transmitted from an old MME that previously served the wireless communication device, and receive a tracking area update transmitted from the wireless communication device. The processing system is configured to, in response to the tracking area update, determine whether or not to select a new serving gateway for the wireless communication device, and upon determining to select the new serving gateway for the wireless communication device, direct the communication transceiver to transfer a reattach instruction for delivery to the wireless communication device.

Abstract: An ePDG is configured to receive an attachment request transmitted from a priority wireless communication device over an internet communication network and responsively transfer a create session request to a P-GW. The P-GW is configured to receive the create session request and responsively transfer a credit control request to a PCRF. The PCRF is configured to receive the credit control request and responsively determine that the priority wireless communication device has a priority modification requirement, generate modified priority data for the priority wireless communication device based on the priority modification requirement, and transfer a credit control answer with the modified priority data to the P-GW. The P-GW is configured to receive the credit control answer with the modified priority data and responsively create a default bearer between the ePDG and the P-GW for the priority wireless communication device with priority service based on the modified priority data.

Abstract: A wireless relay attaches to a wireless base station and broadcasts a wireless hop count. Another wireless relay receives the wireless hop count and attaches to the wireless relay. The other wireless relay increments the wireless hop count and broadcasts the incremented wireless hop count. The wireless relays receive attachment requests from User Equipment (UEs) responsive to their wireless hop counts. The wireless relays exchange user data with the UEs after the attachments.
