METHOD AND SYSTEM TO ASSIGN MOBILE STATIONS TO AN UNLICENSED MOBILE ACCESS NETWORK CONTROLLER IN AN UNLICENSED RADIO ACCESS NETWORK

摘要

The present invention provides a method and architecture on how mobile stations (MS 132) are provisioned about information of an unlicensed mobile access (UMA) network controller (UNC 142). The UNC (142) in accordance with the present invention provides three different logical roles (i.e., provisioning (300), default (302) and serving (304)). More specifically, the present invention provides a method for assigning a mobile station (MS 132) to an unlicensed mobile access (UMA) network controller (UNC 142) in an unlicensed mobile access network (UMAN 102). The MS (132) is connected to a provisioning UNC (402) and discovers a default UNC (404). A serving UNC (406) is then determined to assign the MS (132) to and the MS (132) is assigned to the serving UNC (408). The serving UNC (620) can be the default UNC (612), the provisioning UNC (604) or another UNC.
