Abstract: A node in a telephone network such as a switch stores associations between called and calling parties and colored ringback media played by the called party. Later, when the same calling party calls the called party, the node retrieves the stored ringback media and forwards the media to the calling party on behalf of the called party. In one embodiment, the node comprises a switch. In other embodiments, the node is a central server caching called/calling party combinations and associated ringback media and provides the ringback media forwarding function for a distributed population of called parties. Such called parties may comprise wireless phones.

Abstract: A wireless communication device (WCD) may determine that the WCD has bearer traffic queued for transmission to a radio access network (RAN). The WCD may be configured to transmit the bearer traffic and neighbor reports over a reverse-direction channel of the RAN. The neighbor reports may contain information related to wireless coverage areas. One or more characteristics of the bearer traffic may also be determined. Based on the one or more characteristics of the bearer traffic, the neighbor reports may be scheduled to be transmitted over the reverse-direction channel at a particular rate. The WCD may transmit the neighbor reports over the reverse-direction channel at the particular rate.

Abstract: A method and system for preserving context records is disclosed. The method is operable in a communication system including a wireless network serving user equipment devices (UEs), where the wireless network stores, for each UE served by the wireless network, a context record for the UE. The method involves the wireless network detecting a trigger condition comprising a condition selected from the group consisting of (i) a threshold number of context release messages being transmitted between at least two network entities in the wireless network, wherein the threshold number is greater than one and (ii) a network entity beginning a shut-down process. The method further involves, in response to detecting the trigger condition, the wireless network (i) detaching from the wireless network each UE being served by the wireless network at the time of detecting the trigger condition but (ii) preserving the context records for the detached UEs.

Abstract: A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

Abstract: Disclosed is a method and corresponding system for managing CSFB pre-registration. A first network serving a UE releases the UE from being served by the first network and redirects the UE to transition from being served by the first network to being served by a second network. The first network then detects that the UE has returned to be served by the first network. In response to detecting the return of the UE, and based on the previous releasing and redirecting of the UE, the first network then initiates a pre-registration of the UE with the second network to inform the second network that the UE is now reachable via the first network.

Abstract: Disclosed is a method and corresponding system for dynamically activating a relay in a radio access network (RAN) that includes a plurality of base stations. Each base station may radiate to define one or more respective wireless coverage areas, and each coverage area may operate on one or more carrier frequencies. The RAN may be arranged to receive, from a user equipment device (UE) that is being served by a base station of the RAN on a first carrier frequency, a report indicating threshold low wireless performance on the first carrier frequency. In response to the report indicating threshold low wireless performance, the RAN may be arranged to then activate a relay that functions to communicate with the base station over a relay backhaul interface, and communicate with the UE on a second carrier frequency that is different from the first carrier frequency.

Abstract: Disclosed herein is a mechanism for dynamically varying the process of selecting cell sites to broadcast an alert message. The mechanism involves using the type or other characteristic of the alert message as a basis to choose a particular cell-site selection process or level of precision for defining cell site coverage. For example, given one type of alert message, a particular cell-site selection process and/or level of precision may be used to determine the cell sites in the target area, and given another type of alert message, a different cell-site selection process and/or level of precision may be used to determine the cell sites in the target area.

Abstract: A mobile location system (MLS) may receive a request to provide a representative location of a user equipment device (UE). In response to receiving the request, the MLS may apply a location determination process so as to determine a location of the UE. The MLS may then determine that the determined location of the UE coincides with an existing location of another entity, such as a private address. In response to determining that the determined location of the UE coincides with the existing location of the other entity, the MLS may adjust the determined location to not coincide with the existing location of the other entity. The adjusted determined location may be a road segment, geodetic marker, or property boundary. The MLS may then provide a response to the request, in which the response identifies the adjusted determined location of the UE as the representative location of the UE.

Abstract: A RAN may be configured to receive a first call setup request relating to a first WCD, and a second call setup request relating to a second WCD. The first WCD may communicate using a first air-interface or a second air-interface, and the second WCD my communicate using the second air-interface and not the first air-interface. The RAN may determine that the first WCD and the second WCD are contending for a resource of a wireless coverage area defined using the second air-interface. Based on the first WCD and the second WCD contending for the resource, the first WCD communicating using the first air-interface or the second air-interface, and the second WCD communicating using the second air-interface and not the first air-interface, the RAN may assign the resource to the second WCD.

Abstract: In normal operation, a primary signaling controller in a first RAN manages bearer connectivity and tracking area updates for a UE and further interfaces with a second RAN over a primary signaling interface to facilitate inter-RAN signaling related to transition of the UE from being served by the first RAN to being served by the second RAN, such as circuit-switched fallback signaling. Upon detecting failure of the primary signaling interface, the first RAN is dynamically reconfigured to have such inter-RAN signaling for the UE pass over a secondary signaling interface between the second RAN and a secondary signaling controller of the first RAN, while the primary signaling controller continues to manage bearer connectivity and tracking area updates for the UE.
