Patent Images
1. A method for releasing a connection between a mobile station (MS) and an unlicensed network controller (UNC) initiated by the MS, comprising:
- sending a CLEAR REQUEST message from the MS to the UNC to initiate release of resources corresponding to a connection established between the MS and the UNC, the CLEAR REQUEST message including a plurality of information elements (IEs) including;
a protocol discriminator;
a skip indicator; and
a message type identifying the message as the CLEAR REQUEST message.

Abstract
Techniques for performing messaging between mobile stations (MSs) and UMA network controllers (UNCs) in an unlicensed mobile access network (UMAN). URR (UMA radio resource) messages are exchanged between an MS and one or more UNCs to perform various operations associated with UMAN. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.

8. An unlicensed mobile access network controller (UNC) to operate in an unlicensed wireless network comprising a first radio access network, comprising:
-
a first network interface comprising an Internet Protocol (IP) network interface; a second network interface comprising an Up interface, via which messages are to be transmitted to and received from a mobile station (MS) via an access point communicatively coupled between the MS and the UNC, the Up interface including a plurality of layers implemented over the IP network interface; a third network interface, via which the UNC may be connected to a core network that is accessible to a second radio access network; and one or more modules for generating and/or processing a plurality of messages transmitted over the Up interface to support server-side communications with one or more MS clients in the unlicensed wireless network, the messages comprising; a RELEASE message generated by and sent from the UNC to the MS to initiate release of resources corresponding to a connection established between the UNC and the MS; a RELEASE COMPLETE message received at the UNC from the MS in response to the RELEASE message and processed by the UNC, wherein each of the RELEASE and the RELEASE COMPLETE messages includes a plurality of information elements (IEs) including; a protocol discriminator; a skip indicator; and a message type via which the message may be identified. - View Dependent Claims (9, 10, 11)
