Abstract: Disclosed is an arrangement in which a radio access network detects a trigger such as the RAN being threshold loaded, and the RAN responsively causes each of one or more served UEs to transition from operating in a mode in which the UE would engage in call initiation signaling via the RAN to set up the call extending through the RAN, so the UE would then engage in the call served by the RAN to operating in a mode in which the UE would engage in call initiation signaling via the RAN to instead set up the call extending through another RAN and would transition to be served by the other RAN, so the UE would engage in the call served by the other RAN. As disclosed, one RAN may be an LTE RAN, and the other RAN may be a fallback RAN such as a CDMA or GSM RAN.

Abstract: In accordance with the disclosed methods and systems, while providing a service that enables user equipment devices (UEs) being served by a first network to engage in signaling with a second network via the first network, a controller or other network entity may detect an error condition associated with the service, such as a threshold-high level of signaling or an interface failure. In response to detecting the error condition, base stations in the first network may then direct one or more UEs being served by the first network to refrain from using the given service. As a result, the one or more UEs may refrain from using the given service and may instead use another approach to engage in signaling with the second network, which may enable the one or more UEs to circumvent the error condition until it gets remedied.

Abstract: A first service request, on behalf of a wireless communication device (WCD) may be received. The first WCD may be served by a first base station of a first wireless network provider, and may be subscribed to a second wireless network provider. A home packet gateway (PGW) device, with which to establish an inter-provider bearer path for the first WCD, may be identified. The inter-provider bearer path may include the first base station, a first serving gateway (SGW) device, and the home PGW device. The home PGW device may be operated by the second wireless network provider. In response to determining that the home PGW device is unresponsive, a backup PGW device may be identified. The backup PGW device may be operated by the first wireless network provider. The first SGW device may be instructed to establish intra-provider bearer paths that include the backup PGW device.

Abstract: To help manage resources in a cellular wireless communication system, a base station may track air interface resource allocation for each UE the base station is serving with a call and may identify one or more of the UEs or calls as candidates for handover from the base station on grounds that air interface resource allocation to each of the identified one or more UEs is high. Upon receipt of a request from a UE to initiate a new call, the base station may then predict based at least on that UE's channel quality what the air interface resource allocation rate will be for the requested call. And if the predicted rate for the given UE is threshold low, the base station may select one of the candidate UEs and force a handover of the selected UE's call from the base station.

Abstract: A first home packet gateway (PGW) device may receive a binding update message on behalf of a wireless communication device (WCD). The first home PGW device may be associated with a first pool of Internet Protocol (IP) addresses, and the WCD may be assigned a particular IP address. It may be determined that the first pool of IP addresses does not include the particular IP address, and that the particular IP address is included in a second pool of IP addresses that is associated with a second home PGW device. Possibly in response to determining that the particular IP address is included in the second pool of IP addresses that is associated with the second home PGW device, the first home PGW device may forward the binding update message to the second home PGW device.

Abstract: A method and system for responding to a call-teardown request generated, for instance, as a result of a user equipment device (UE) losing coverage of a first serving radio access network (RAN) while the UE is engaged in a call with another party. A signaling intermediary receives the call-teardown message en route from a first call server to a second call server and responsively determines whether the UE is now served by a second RAN. Responsive to determining that the UE is served by the second RAN, the intermediary arranges for establishment of a new call connection with the UE via the second RAN and for linking of the new call connection with an existing leg of the call with the other party, and the intermediary discards the call-teardown message rather than forwarding it along to the second call server.
