Abstract: After receiving a message that defines an initial target area for distribution of an alert, a wireless carrier network may identify a first set of one or more coverage areas that are fully encompassed within the initial target area and a second set of one or more coverage areas that are partially encompassed within the initial target area. For each partially-encompassed coverage area, the network may then define a respective target area that is less geometrically complex than the initial target area. In turn, the network may broadcast the alert (1) in each fully-encompassed coverage area in a manner that directs a recipient device to output the alert regardless of the device's location and (2) in each partially-encompassed coverage area in a manner that directs a recipient device to output the alert only if the device's location is encompassed within the respective target area for the coverage area.

Abstract: A method and corresponding system is provided to help mitigate the potential quality-of-service degradation associated with fast-moving UEs operating in a network that provides higher-bandwidth frequency channels in some but not all wireless coverage sectors. In accordance with the method, a base station may evaluate a UE's current speed and, when that speed exceeds a threshold speed, the base station may instruct the UE to register on a low-bandwidth channel rather than a higher-bandwidth channel. Registering for service on a low-bandwidth channel instead of a higher-bandwidth channel may help ensure that the UE maintains a consistent quality of service as the UE moves from coverage area to coverage area. Further, the base station may also query nearby base stations to determine whether there exists a sufficient number of base stations that operate on higher-bandwidth channels. If so, the base station may instruct the UE to use a higher-bandwidth channel.
Abstract translation: 提供了一种方法和相应的系统，以帮助减轻与在一些但不是全部无线覆盖扇区中提供更高带宽频率信道的在网络中操作的快速移动UE相关联的潜在服务质量下降。 根据该方法，基站可以评估UE的当前速度，并且当该速度超过阈值速度时，基站可以指示UE在低带宽信道而不是较高带宽信道上注册。 在低带宽信道上注册服务而不是较高带宽信道可能有助于确保UE随着UE从覆盖区域移动到覆盖区域而保持一致的服务质量。 此外，基站还可以查询附近的基站，以确定是否存在在较高带宽信道上操作的足够数量的基站。 如果是，则基站可以指示UE使用较高带宽信道。

Abstract: A mobility management entity (MME) may receive a request that identifies an access point name (APN) for a packet data connection for a wireless communication device (WCD). The APN may be authorized by the WCD according to a service profile in a home subscriber server (HSS), and the APN may be associated with a subscribed packet data policy. However, if the MME determines that it cannot validate the request (e.g., because the HSS is unreachable or non-responsive), the MME may send to a packet gateway a session request that identifies the WCD and includes a dummy APN. The dummy APN is associated with a substitute packet data policy that differs from the subscribed packet data policy. Based on the session request including the dummy APN, the packet gateway may establish a packet data session for the WCD in accordance with the substitute packet data policy.
Abstract translation: 移动性管理实体（MME）可以接收标识用于无线通信设备（WCD）的分组数据连接的接入点名称（APN）的请求。 APN可以根据家庭用户服务器（HSS）中的服务简档由WCD授权，并且APN可以与订阅的分组数据策略相关联。 然而，如果MME确定它不能验证该请求（例如，因为HSS不可达或不响应），则MME可以向分组网关发送识别WCD并包括虚拟APN的会话请求。 虚拟APN与不同于订阅分组数据策略的替代分组数据策略相关联。 基于包括虚拟APN的会话请求，分组网关可以根据替代分组数据策略为WCD建立分组数据会话。

Abstract: Disclosed herein are systems and methods for dynamically controlling active-to-dormant timers in radio access networks (RANs). One embodiment takes the form of a method that involves a system detecting a triggering event, and responsively identifying a current access-channel occupancy (ACHO). The method further involves the system increasing an active-to-dormant timer for at least one access terminal when the identified current ACHO exceeds a first threshold, and decreasing an active-to-dormant timer for at least one access terminal when the identified current ACHO is less than a second threshold.

Abstract: A method to dynamically configure a base station based on evaluation of whether nearby and/or neighboring base stations operate on a preferred coverage frequency. For instance, the base station could be configured to broadcast as a start-scanning threshold value a relatively high value in response to determining that a base station operating on the preferred coverage frequency is located within a predefined threshold distance. Further, the base station could be configured to broadcast as the start-scanning threshold value an intermediate value in response to determining that no nearby base station operates on the preferred coverage frequency but at least one base station that is a handover neighbor operates on the preferred coverage frequency. And the base station could be configured to broadcast as the start-scanning threshold value a relatively low value in response to determining that no nearby base stations or handover neighbors operate on the preferred coverage frequency.

Abstract: Embodiments described herein may help to provide a delayed zone-update process. An exemplary method may involve a user entity, which is initially operating in a first of a plurality of multi-coverage-area zones in a radio access network (RAN), subsequently determining that the user entity has moved into a second multi-coverage-area zone of the RAN, wherein the user entity is located in a first coverage area of the second multi-coverage-area zone. In response, the user entity may refrain from sending a registration message to register in the second multi-coverage-area zone until the earlier of: (i) a threshold period of time elapsing and (ii) the user entity moving into another coverage area in the second multi-coverage-area zone that is different from the first coverage area.

Abstract: Disclosed is a method and apparatus and system for managing frequency use in a system where multiple air interface protocols are in use. When a wireless communication device (WCD) is operating under a particular air interface protocol on a particular frequency channel, the WCD detects a threshold signal under another air interface protocol, and the WCD responsively transitions from operating under the particular air interface protocol on the particular frequency channel to operating under the particular air interface protocol on a different frequency channel. The method may thereby help to reduce likelihood of interference.

Abstract: Systems and methods are provided for an optimized mobile-IPv6 encapsulation. A mobile node sends packets to a correspondent node by encapsulating a packet using an IPv6 routing extension header, and reverse tunneling the packet to a home agent. The home agent modifies the packet and forwards it to the correspondent node. When the correspondent node sends packets to the mobile node's home address, the home agent intercepts the packet, encapsulates the packet with an IPv6 routing extension header, and tunnels the packet to the mobile node. Consequently, because packets are tunneled using IPv6 routing extension headers, the amount of overhead in each encapsulated packet is reduced, thus increasing the available bandwidth in a network.
Abstract translation: 为优化的移动IPv6封装提供了系统和方法。 移动节点通过使用IPv6路由扩展报头封装分组，将分组发送到对端节点，并将分组反向隧道传送到归属代理。 归属代理修改数据包并将其转发给对端节点。 当通信节点向移动节点的归属地址发送数据包时，归属代理拦截数据包，用IPv6路由扩展报头封装数据包，并将数据包隧道传送到移动节点。 因此，由于数据包使用IPv6路由扩展头隧道化，所以每个封装数据包中的开销量减少，从而增加网络中的可用带宽。

Abstract: A radio access network (RAN) may receive a call setup request from a wireless communication device (WCD). The call setup request may indicate that the WCD supports a first media codec. The RAN may obtain a set of candidate wireless coverage areas for serving the WCD. A first subset of the candidate wireless coverage areas may support the first media codec, and a second subset of the candidate wireless coverage areas might not support the first media codec. The RAN may assign traffic channels to the WCD, such that the assigned traffic channels include traffic channels from at least two of the first subset of the candidate wireless coverage areas, but do not include traffic channels from any of the second subset of the candidate wireless coverage areas. The RAN may communicate with the WCD substantially simultaneously via the assigned traffic channels using the first media codec.
