摘要:
A system, method, and apparatus for maintaining the status of communications between a wireless client and a content source is presented herein. During periods where the wireless link at the wireless client has deteriorated, a wireless content switch prevents timers at the content source from expiring by transmitting an acknowledgment message to the content source. The acknowledgement also stops the content source from transmitting data packets to the wireless client by indicating a zero window size. Additionally, during the time period that the wireless link to the wireless client is deteriorated, the wireless content switch responds to communications from the content source for the wireless client.

A real-time exchange (RTX) interfaces to a wireless communications system to provide enhanced features for advanced voice services (AVS), which include instant messaging interworking.
摘要:
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.
摘要:
A system and method for transmitting data packets to a wireless client is shown. The data packets are received by a wireless content switch in the wireless network. The wireless content switch determines a quality of service value for the wireless client. The wireless content switch assigns the priority of transmission for the data packet based on the assigned quality of service value. The data packet is transmitted according to the priority.

A system and method for transmitting data packets to a wireless client is presented herein. The data packets are received by a wireless content switch in the wireless network. The wireless content switch assigns the priority of transmission for the data packet based on both the purchased level of service by the subscriber receiving the data packet, as well as the application the data packet is transmitted.
摘要:
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.
