Traffic control for roaming subscribers

摘要

A method of controlling load within a cellular telecommunications network due to packet data traffic, where packet data traffic associated with subscribers roaming in said network is broken out to respective access gateways in the subscribers home networks. The method comprises, within said cellular telecommunications network, identifying peer networks whose subscribers are currently roaming in the network. Upon detection of a congestion event within the network, a notification is caused to be sent to one or more of said peer networks. Upon receipt of the notification at the or each peer network, a reduction in the packet data traffic bandwidth available to those of said roaming subscribers belonging to the peer network is caused, wherein the packet data traffic associated with those subscribers in said cellular telecommunications is reduced.

1. A method of controlling load within a cellular telecommunications network due to packet data traffic, the method comprising:
receiving from the cellular telecommunications network an overload report that indicates an overload within said cellular telecommunications network and that identifies one or more peer cellular telecommunications networks as having roaming subscribers contributing to said overload; identifying one or more actions to be applied in said one or more peer networks based on inspection of a database containing inter-operator roaming agreements; and sending a notification to each of the one or more peer networks indicating the one or more identified actions to be applied, each notification including an identity of the cellular telecommunications network and a cell identity that identifies a respective cell in which the overload is occurring.
