Embodiment Construction

[0011] figure 1 A wireless communication system 10 is described that is operable in accordance with aspects of the present invention. The wireless communication system 10 generally includes a plurality of wireless devices (also referred to as remote stations, subscriber units, mobile stations, or user equipment) 12a-12d, a plurality of base stations (also referred to as base transceiver stations (BTS) or Node Bs) 14a-14c , a base station controller 16 (BSC) (also known as a radio network controller or packet control function), a mobile switching center (MSC) or switch 18 , and a public switched telephone network (PSTN) 22 . For brevity, figure 1 Four wireless devices 12a-12d, three base stations 14a-14c, one BSC 16 and one MSC 18 are shown. Those skilled in the art will appreciate that any number of wireless devices 12, base stations 14, BSCs 16, and MSCs 18 are also possible.

[0012] In one embodiment, the wireless communication system 10 is a packet data service network....

Abstract

A method, apparatus, and computer-readable media for accessing supplementary services from a wireless device in a multi-mode environment is disclosed. A master set of service codes for the multi-modeenvironment is provided. The master set of service codes is associated with supplementary services offered by a plurality of wireless networks that are compatible with the wireless device. At least one service code from the master set of service codes is mapped to a corresponding at least one network-specific service code to request at least one supplementary service of one of the plurality of wireless networks.

Description

[0001] Related References [0002] This application claims priority from US Provisional Application Serial No. 60 / 387,157, filed May 29, 2002, entitled "Method and Apparatus For Accessing Supplementary Services With A Multi-Mode Wireless Device." technical field [0003] The present invention relates to data communications, and more particularly to communications using multi-mode wireless devices to access supplementary services. Background technique [0004] Supplementary services are widely used in wireless networks. Supplementary services (referred to as "cellular features" in the CDMA and TDMA specifications), such as call forwarding, call waiting, call blocking, etc., enhance the basic voice calling services of a typical wireless service plan. Supplementary services are accessed by service codes and man-machine interface (MMI) programs. The service code is a special telephone number consisting of 0, 1, . . . 9, * and # in a predefined format according to various wirel...
