Exemplary methods and apparatuses are provided for throttling wireless traffic during congestion in radio access networks. Embodiments are provided that may assist service providers to reduce new requests for network resources during congestion and allow existing lower priority traffic to be pre-empted with a backoff time to allow a new request with higher priority traffic to be served. In response to a request for an additional connection to a radio access network from a terminal device that has one or more existing connections in the radio access network, an access network controller will compare a priority level of a requested connection to a priority level of other existing connections in the radio access network. The access network controller may reject or grant the request based on the comparison and send the terminal device a backoff time value and a congestion indicator.
1. A method comprising:
receiving at an access network controller a request from a core network component to provide an additional connection to a mobile communications device that has one or more existing connections to a radio access network managed by the access network controller;
determining at the access network controller whether at least a portion of the radio access network is in an overload condition; and
sending at the access network controller a first message to the core network component, the first message comprising a time value that specifies an amount of time required before the mobile communications device can initiate another request for network resources.
