A first base station receives, from a first core network entity, one or more packets for a wireless device in a radio resource control inactive state. The first base station sends, to a second core network entity and in response to a failure of a radio access network (RAN) paging procedure for the wireless device, a first message indicating the failure of the RAN paging procedure. The first base station receives a second message comprising a tunnel endpoint identifier of a third base station. The first base station sends, to the third base station, the one or more packets based on the tunnel endpoint identifier.

A location area management method and a device, the location area management method including receiving, by a single radio controller, a first request message, where the first request message is used by user equipment UE to request a location update, generating, by the single radio controller, a paging area list of the UE according to the first request message, where the paging area list includes a location area identity of a location area of at least one network standard, adding, by the single radio controller, the paging area list of the UE to a first response message, and sending the first response message to the UE.

Systems, methods, and computer-readable storage media providing highly scalable and fault tolerant notification systems are disclosed. Disclosed notification systems may be configured to: receive a plurality of notification requests including message content and recipient information, which may be allocated to at least one notification engine for processing. A notification engine may be configured to: generate a plurality of attempts corresponding to notification requests allocated for processing by the first notification engine and assign each generated attempt to a particular attempt queue. A plurality of connectors may be configured to: select a set of attempts for transmission from the plurality of attempt queues, transmit the set of attempts via at least one communication network.
