Problems solved by technology

[0005] Furthermore, in network interworking, there is no capability to tell a wireless terminal that it has a dual-mode radio capability, nor is there any capability to rely on one of the networks it communicates with to be aware of its interworking capability so that the wireless terminal has the ability to communicate with both networks. The enhanced ability to communicate with either

Embodiment Construction

[0014] The problem solved by the present invention is a mechanism by which a terminal supporting both GPRS and WLAN or both 3G and WLAN can report its WLAN capabilities to the GPRS / UMTS network it supports. At the same time, the present invention can moreover recognize the mechanism by which the 3G network can indicate that 3G or packet switch domain services via WLAN are available.

[0015] figure 1 A simple block diagram showing a network where UMTS and WLAN are integrated. WTRUs 12, 14, and 16 communicate with the network via respective radio links (RL-1, RL-2, and RL-3). More particularly, the WTRU 12 communicates with a GSM radio access network (RAN), the WTRU 14 communicates with a 2.5 / 3G RAN, and the WTRU 16 communicates with a WLAN access point (AP). WTRUs 12 and 14 may be cellular telephones, while WTRU 16 is a laptop computer, personal digital assistant (PDA) or other similar device with an appropriate card to communicate with the WLAN AP.

[0016] The GSM RAN com...

Abstract

Method and apparatus for enabling a wireless terminal to communicate the dual-mode capabilities and reporting the interworking capabilities of the two networks with which the wireless terminal have the added capability of obtaining services from either one of the interworking networks.

Description

technical field [0001] The present invention relates to dual mode capable WTRUs, and more particularly to methods and apparatus for reporting dual mode capability and for reporting availability of network interworking. Background technique [0002] Wireless Local Area Networks (WLAN) interworking with General Packet Radio Service / Global Mobile Telecommunications System / Third Generation (GPRS / UMTS / 3G) networks has led to its current evolution of WLAN resulting in a common housing containing two radio units Products (for example: cards supporting 802.11b+GPRS air interface and 802.11b+UMTS air interface). These units can be separate cards, or can also be integrated in a common card. [0003] Hereinafter, a wireless transmit / receive unit (WTRU) includes, but is not limited to, user equipment, mobile station, fixed or mobile subscriber unit, paging or any other type of device capable of operating in a wireless environment. And when mentioned below, a base station (BS) includes...
