Redirection in heterogeneous overlay networks
First Claim
Patent Images
1. A method for network redirection in overlay heterogeneous networks, the method comprising:
- receiving a call connection request from user equipment;
identifying a user preferred network based on predetermined network access priority information associated with the user equipment;
determining network redirection based on the user preferred network; and
creating network redirection information based on the determined network redirection,wherein the determining the network redirection includes;
determining whether a current serving network is the user preferred network;
determining whether a network load of a next serving network has not reached a first reference value when the current serving network is not the user preferred network;
determining that performing the network redirection is necessary when the network load has not reached the first reference value; and
determining that performing the network redirection is unnecessary when at least one of the current serving network is the user preferred network and the network load reaches the first reference value.

Abstract
The disclosure is related to distributing a network load in overlay heterogeneous networks. A call connection request may receive from user equipment. A user preferred network may be identified based on predetermined network access priority information associated with the user equipment. Network redirection may be determined based on the user preferred network. Network redirection information may be created based on the determined network redirection.

12. A method for network redirection in overlay heterogeneous networks, the method comprising:
-
receiving a call connection request from user equipment; determining availability of network redirection information associated with the user equipment; and performing a network redirection determination procedure at least one of (i) when the network redirection information is unavailable and (ii) when the network redirection information is available and a time limit included in the network redirection information is expired, wherein the network redirection determination procedure includes; identifying a user preferred network based on predetermined network access priority information associated with the user equipment; determining whether a current serving network is the user preferred network; determining whether a network load of a next serving network has not reached a first reference value when the current serving network is not the user preferred network; determining that performing network redirection is necessary when the network load has not reached the first reference value; and determining that performing the network redirection is unnecessary when at least one of the current serving network is the user preferred network and the network load reaches the first reference value. - View Dependent Claims (13)

14. A method for network redirection in overlay heterogeneous networks in user equipment, the method comprising:
-
receiving network redirection information from a first base station when connection between the user equipment and a current serving network is released; and transmitting a call connection request message to a second base station for a new communication service based on the received network redirection information, wherein the received network redirection information indicates the second base station of a next serving network, wherein the network redirection information is created through a network redirection determination procedure including; identifying a user preferred network based on predetermined network access priority information associated with the user equipment; determining whether the current serving network is the user preferred network; determining whether a network load of the next serving network has not reached a first reference value when the current serving network is not the user preferred network; determining that performing network redirection is necessary when the network load has not reached the first reference value; determining that performing the network redirection is unnecessary when at least one of the current serving network is the user preferred network and the network load reaches the first reference value; and creating the network redirection information based on a network redirection determination. - View Dependent Claims (15, 16)

17. An apparatus for network redirection in overlay heterogeneous networks, the apparatus comprising:
-
a receiving unit configured to receive predetermined network access priority information associated with user equipment; and a redirection determination unit configured to determine network redirection based on the predetermined network access priority information, and to create network redirection information based on the determined network redirection, wherein the redirection determination unit is configured to; identify a user preferred network based on the predetermined network access priority information; determine whether a current serving network is the user preferred network; determine whether a network load of a next serving network has not reached a first reference value when the current serving network is not the user preferred network; determine that performing the network redirection is necessary when the network load has not reached the first reference value; and determine that performing the network redirection is unnecessary when at least one of the current serving network is the user preferred network and the network load reaches the first reference value. - View Dependent Claims (18, 19, 20)
