Abstract:
1. A method comprising: determining, by a management gateway, a paging priority value associated with a bearer between a mobile device and a forwarding gateway; the management gateway providing the paging priority value to the forwarding gateway; determining, by the management gateway, a paging priority threshold based on a load condition of the management gateway; storing, at the forwarding gateway, (i) the paging priority threshold for at least one packet delivery network with a connection to the mobile device and (ii) the paging priority value; comparing the paging priority value and the paging priority threshold for a given packet delivery network when a packet is received at the forwarding gateway from the given packet delivery network for the mobile device over the bearer, wherein the forwarding gateway communicates with the mobile device via the bearer; and sending a data arrival notification from the forwarding gateway to the management gateway to cause a core network to page the mobile device to receive data queued for the mobile device in the core network if the paging priority value exceeds the paging priority threshold, and delaying sending the data arrival notification until the expiration of a delay value timer if the paging priority value does not exceed the paging priority threshold, the paging priority value and the paging priority threshold thus interacting to produce a desired frequency of paging to the mobile device from the core network for the given packet delivery network, and to reduce paging based on congestion.
