Thereafter, second or subsequent talkbursts or volleys are transmitted by the RTX from the originating mobile to the terminating mobiles on the circuit channels.
A converged mobile-Web communications solution interfaces to both a mobile phone network and an Internet or Intranet network, so that services that are provided to mobile phones in the mobile phone network are also provided to Web clients in the Internet or Intranet network.
A real-time exchange (RTX) interfaces to a wireless communications system to provide enhanced features for advanced voice services (AVS), which include Voice Activated Floor Management, Voice Short Message Services (SMS) and Address Book Backup.
A system for providing advanced voice services (AVS) in wireless communications systems includes a Real-Time Exchange (RTX) that interfaces to a wireless communications network to provide the AVS therein, wherein the AVS comprise Closed User Groups and Limiting Mobility. The Closed User Groups allow a group of users to make and receive calls only to other members of a group, and calls outside of the group are disallowed. The Limiting Mobility uses location information to restrict a mobile unit to service within one or more specified systems, cells or location areas.
A client application that provides advanced voice services (AVS), such as Push-to-Talk (P2T), Push-to-Conference (P2C), Upgrade to Conference (upgrade from P2T to P2C), Push-to-Message (P2M) and group SMS (Short Message Service), on wireless handsets and networks using a Binary Runtime Environment for Wireless (BREW™), which is an open architecture that serves as a common platform for wireless applications. The functionality provided by the BREW™ AVS client application includes menu displays for the handset, as well as user interaction with the menu displays. Specifically, the functionality includes One-to-One Conference Calls, One-to-Many Conference Calls, Dynamic Conference Calls, One-to-One Messaging, or One-to-Many Messaging.
A real-time exchange (RTX) interfaces to a wireless communications system to provide enhanced features for advanced voice services (AVS), which include location-based information, voice portal integration, push ring tones and voice message screening.

Press-to-connect for wireless communications systems
An advanced voice service known as “Press-to-Connect” for wireless communications systems. A real-time exchange interfaces to the wireless network to provide a Press-to-Connect (PTC) call between an initiator and one or more recipients, wherein the PTC call comprises a time-limited Press-to-Talk (P2T) call. The real-time exchange uses a Talk Timer to limit how long the user may press a button and talk (i.e., the Talk Timer limits the length of each continuous “Talk” session of the call), before a “Talk” session of the call in the wireless network is ended, and the real-time exchange uses a Call Timer to limit how long the call can last (i.e., the Call Timer limits the overall length of the call), before the call in the wireless network is ended.
Subscriber identity module (SIM) enabling advanced voice services (AVS) including push-to-talk, push-to-conference and push-to-message on wireless handsets and networks
A Subscriber Identity Module (SIM) that stores the logic and data for providing advanced voice services (AVS) including Push-to-Talk (P2T), Push-to-Conference (P2C), Upgrade to Conference (upgrade from P2T to P2C), Push-to-Message (P2M) and group SMS (Short Message Service), on wireless handsets and networks. When inserted into a handset, the AVS functionality is available for use on the handset, wherein the functionality includes menu displays for the handset, as well as user interaction with the menu displays. The SIM also stores logic and data for providing presence and availability functions on the handset. In addition, the SIM stores the logic and data for providing contact and group management on the handset.
Advanced voice services, such as Push-to-Talk (P2T), Push-to-Conference (P2C), Upgrade to Conference (upgrade from P2T to P2C), Push-to-Message (P2M) and group SMS (Short Message Service), are provided for wireless networks. These services are provided by an architectural framework that interfaces into the wireless network in order to provide group call setup and messaging. Handset pre-provisioning reduces customer interaction in the process of activating handsets for use in the network. Presence messages are communicated between handsets and a real-time exchange using the Short Message Service (SMS), but without having to transmit the messages through a Short Message Service Center (SMSC) gateway, but instead the messages are transmitted using Mobile Application Part (MAP) interface connecting the real-time exchange directly to a mobile switching center.
Group voice services are provided in a wireless network, such as a cellular telephone network (104, 108, 116), by a dispatch gateway (102) that interfaces to the wireless network to provide the group voice services therein, wherein both the dispatch gateway and mobiles (120) that use the group voice services communicate with each other using cell setup and in-band signaling within the wireless network.
A roaming gateway for support of advanced voice services while roaming in wireless communications systems. The roaming gateway supports push-to-talk (P2T) calls, or other advanced voice services, when P2T subscribers roam from their home network (i.e., a network operated by their service provider where the subscriber's profile resides) into a foreign network (i.e., a network operated by another service provider). The roaming gateway is a specialized version of a real-time exchange that is located in the home network and is connected to mobile switching centers in foreign networks, so that the mobile switching centers in the foreign networks need not be programmed for the advanced voice services.
Architecture, client specification and application programming interface (API) for supporting advanced voice services (AVS) including push to talk on wireless handsets and networks
An architecture, client specification and application programming interface (API) for supporting advanced voice services (AVS) for use in handsets in order to support advanced voice services (AVS) for wireless communications systems. The handset or mobile unit executes a client application therein for performing the call setup and in-band signaling with the wireless network for the group voice services, and executes a presence/group management application therein for performing presence and group management functions related to the group voice services in the mobile unit.
