Network interworking
First Claim
1. A method of operating a mobile terminal for network interworking, the method comprising:
- receiving, from a first network, a first parameter associated with a preference for offloading a data flow from the first network to a second network;
receiving, from the second network, a second parameter associated with a network load level of the second network through a beacon packet;
performing a first determination of whether to offload at least one data flow according to a first criterion of comparing the first parameter to a random value or a pseudorandom value and a second criterion of comparing the second parameter to a threshold; and
if a timer associated with offloading evaluation expires, performing a second determination of whether to maintain the offloading of the at least one data flow according to the first and second criterion using a third parameter associated with a preference for offloading a data flow from the first network to the second network, and a fourth parameter associated with a network load level of the second network,wherein the third parameter corresponding to the first parameter is received from the first network after receiving the first parameter, andwherein the fourth parameter corresponding to the second parameter is received from the second network after receiving the second parameter.

Abstract
A method of operating a mobile terminal for network interworking is provided. The method includes receiving at the mobile terminal a first parameter from a first wireless communication network indicating a preference for offloading a new or current data flow to another network, the first parameter comprising a value within a first range. The method further comprises obtaining at the mobile terminal a random or pseudorandom value within a second range that at least partially overlaps the first range. The method further comprises determining whether to initiate or maintain at least one data flow between the mobile terminal and the first network or another network according to the first parameter and the random or pseudorandom value.
