Abstract

Methods for performing various operations via unlicensed mobile access (UMA) radio link control (URLC) messages in an unlicensed mobile access network (UMAN). The UMAN comprises a first radio access network that may be employed for accessing data services provided by a core network comprising a second radio access network. URLC messages are exchanged between mobile stations (MSs) and UMA network controllers (UNCs) to perform various operations associated with the UMAN. An MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to a UNC via an IP network. The URLC messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.

Claims

1. A method for facilitating operations in an unlicensed mobile access network (UMAN), comprising:

establishing a dedicated connection between a mobile station (MS) and the UMAN via a UMA network controller (UNC);

establishing a TCP (transmission control protocol) session between the MS and the UNC;

sending unlicensed mobile access (UMA) radio link control (URLC) messages between the MS and the UNC to facilitate corresponding operations, each URLC message including,

a protocol discriminator; and

a message type via which the message may be identified; and

paging the MS for GPRS PS services from the UNC using a URLC-PS-PAGE message, the URLC-PS-PAGE message including a Mobile Identity IE from which the MS can be identified.
