Abstract: A wireless data communication network distributes network addresses to wireless relays. The network receives attachment requests from the wireless relay over wireless access points and transfers network address requests to a network address server. The network receives network address responses from the network address server having network addresses for the wireless relay. The network stores the network addresses for the wireless relay in a memory and transfers the network addresses to the wireless relay. The network wirelessly exchanges user data with the wireless relay. The network receives subsequent attachment requests from the wireless relay and retrieves the network addresses for the wireless relay from the memory without re-using the network address server. The network transfers the network addresses to the wireless relay and wirelessly exchanges user data with the wireless relay.

Abstract: As IMS-based sessions are established for UEs served by a relay base station, the IMS platform will signal to a core network to request setup of bearers for carrying traffic of the IMS-based sessions and will identify the relay base station serving the UEs. Based on this IMS signaling messages identifying the relay base station serving the UEs for which the bearers are being set up, the core network will track a count of such bearers established for UEs served by the relay base station. And upon detecting that the tracked count reaches a threshold level, the core network will trigger adjustment of a maximum bit rate and/or other QoS attribute of a relay bearer established for providing aggregate wireless backhaul connectivity for the relay base station.

Abstract: A wireless access point transfers first user data to a first User Equipment (UE) in first carrier-aggregated resource blocks according to an initial UE Carrier Aggregation (CA) schedule. The wireless access point transfers second user data to a wireless relay in second carrier-aggregated resource blocks according to an initial relay CA schedule. The wireless relay transfers the second user data to a second UE. The wireless access point translates the amount of first user data into a new UE CA schedule and a new relay CA schedule. The wireless access point transfers third user data to the first UE in third carrier-aggregated resource blocks according to the new UE CA schedule. The wireless access point transfers fourth user data to the wireless relay in fourth carrier-aggregated resource blocks according to the new relay CA schedule. The wireless relay transfers the fourth user data to the second UE.

Abstract: A Long Term Evolution (LTE) network connects wireless communication devices to an Internet. In the LTE network, a Packet Data Network Gateway (P-GW) exchanges user communications between the wireless communication devices and the Internet. The P-GW determines a number of additional wireless communication devices the P-GW can serve and transfers the number to a Mobility Management Entity (MME). The MME allocates a new wireless communication device to the P-GW based on the number of additional wireless communication devices reported by the P-GW. The MME may redirect one of the wireless communication devices to the P-GW based on the number.

Abstract: A wireless base station receives attachment signaling for User Equipment (UE) from a wireless repeater chain and identifies a number of repeater hops for the UE between the base station and a serving wireless repeater. The base station transfers signaling indicating the UE ID and the number of wireless repeater hops. A network controller receives the signaling and selects data services for the UE based on the UE ID and the number of wireless repeater hops. The network controller exchanges signaling indicating the selected data services for the UE with a network element to deliver the data services to the UE. The network controller transfers signaling indicating the UE ID and the selected data services to the wireless base station. In some examples, the data services comprise Access Point Names (APNs), and the network controller comprises a Mobility Management Entity (MME).

Abstract: A gateway or other entity will detect when the number of relay base stations served by a relay-WCD changes and will responsively modify a configuration of a bearer that extends between the relay-WCD and the gateway. For instance, in response to detecting an increase in the number of relay base stations served by the relay-WCD, the entity could increase a guaranteed minimum bit rate and/or other quality of service level of the bearer. Or in response to detecting a decrease in the number of relay base stations served by the relay-WCD, the entity could decrease a guaranteed minimum bit rate and/or other quality of service level of the bearer.

Abstract: A method and system to help control message routing in a scenario where a client device is registered with a media system via a first network and the media system is configured by default use the first network as a primary route for routing messages to the WCD. Per the disclosure, the media system will detect, while the client device is so registered via the first network, that a second network is serving the client device with a voice call, and the media system will responsively be reconfigured to use the second network as a primary route for routing of messages destined to the client device. Further, the media system may then subsequently detect that the voice call has ended, and the media system may responsively revert to being configured to use the first network as the primary route for routing of messages destined to the client device.

Abstract: A wireless communication network modifies a non-Guaranteed Bit Rate (non-GBR) bearer through a wireless repeater chain into a Guaranteed Bit Rate (GBR) bearer. A wireless access node exchanges user data with User Equipment (UE) over the non-GBR bearer through the wireless repeater chain. The wireless node monitors latency of the user data exchange over the non-GBR bearer through the wireless repeater chain. When the latency of the non-GBR bearer through the wireless repeater chain exceeds a latency threshold, the wireless node transfers a bearer modification request for the UE to a core packet network. The wireless node receives a bearer modification instruction for the UE from the core packet network to modify the non-GBR bearer into a GBR bearer. In response, the wireless node modifies the non-GBR bearer into the GBR bearer and exchanges user data with the UE over the GBR bearer through the wireless repeater chain.

Abstract: A method and system are disclosed for a base station to manage air interface communications with a user equipment device (UE) served by the base station. The base station will determine whether the served UE is a relay-UE that provides wireless backhaul connectivity for a relay base station and whether the relay base station serves at least a threshold extent of delay-sensitive communication traffic. Based on a determination that the served UE is a relay-UE and that the relay base station serves at least the threshold extent of delay-sensitive communication traffic, the base station will responsively cause the relay-UE to be served by the base station on a particular carrier frequency, in an effort to reduce a total delay resulting from the wireless relay arrangement.

Abstract: A wireless network access point and User Equipment (UEs) communicate over Base Station-to-Device (BS2D) traffic links. The wireless network access point receives status reports from the UEs that form a Device-to-Device (D2D) communication group. The wireless network access point filters the UEs in the D2D communication group based on a signal strength threshold and a buffer capacity threshold to identify a candidate set of the UEs. The wireless network access point further prioritizes the candidate set based on buffer status reporting frequency of the UEs to select one of the UEs as the D2D communication master for the D2D communication group.

Abstract: A wireless communication network selects Modulation and Coding Schemes (MCS) for wireless relays. A wireless network controller determines the amount of wireless access Access Point Names (APNs) that are served by a User Equipment (UE) in the wireless relay. The network controller selects an MCS for the UE in the wireless relay based on the amount of the wireless access APNs served by the UE. The network controller directs a wireless base station and the UE in the wireless relay to use the selected MCS. The UE in the wireless relay exchanges user data with the multiple wireless access points that serve other UEs. The UE in the wireless relay exchanges the user data with the wireless base station using the selected MCS. The network controller may comprise a Long Term Evolution (LTE) Mobility Management Entity (MME), and the wireless access points may comprise LTE eNodeBs.

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 wireless communication network controls data services that are delivered over a wireless access point. The wireless access point broadcasts service identifiers for the data services to user communication devices. The user communication devices and the wireless access point exchange the user data for the data services. The wireless access point and a network gateway exchange the user data for the data services. The network gateway processes the user data to determine if one of the data services falls below a Quality-of-Service (QoS) threshold. If one of the data services falls below its QoS threshold, then the network gateway transfers an instruction to stop wirelessly broadcasting the service identifier for the data service. The wireless access point receives the instruction and stops its wireless broadcast of the service identifier for the data service.

Abstract: A method, apparatus, and system, in which a network detects a communication failure between a gateway and a policy server, and the network responsively causes at least one user equipment device (UE) having at least one bearer connection with that gateway to detach and reattach so as to facilitate set up of at least one new bearer connection between the UE and a different gateway. Optimally, the different gateway would not have a similar communication failure with the policy server, so that the at least one new bearer connection can be successfully set up between the UE and the different gateway, and one or more other bearers can be successfully set up between the UE and the different gateway.

Abstract: A wireless communication device (WCD) transmits to a first serving system a data-connection request that requests a packet data connection. A mobility management entity (MME) determines that an authentication procedure for authenticating the WCD for the requested packet data connection is unavailable. In response, the MME initiates a handover of the WCD from the first serving system to a second serving system. The first and second serving systems use different air interface protocols. When the handover has been successfully completed, the MME stores an indication that the WCD has been diverted to the second serving system. The MME may subsequently determine that the authentication procedure has become available. In response, the MME determines whether the WCD is associated with a valid subscriber profile. If so, the MME requests the second serving system to invite the WCD to connect to the first serving system.
