Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system and method for efficient handoff are presented herein. A wireless content switch is placed in the wireless packet data network and detects initiated handoffs. Responsive thereto, the wireless content switch delays completion at the handoff for a predetermined period of time and causes the content source to temporarily stop transmitting additional packets. Each of the packets that were transmitted prior to temporarily stopping the content source are transmitted to the wireless client during the predetermined period of time that the handoff is delayed. Upon completion of the predetermined period of time, the handoff is permitted to proceed to completion. Because each of the packets transmitted during the pendency of the handoff were transmitted to the wireless client, prior to completion of the handoff, there is no requirement for a tunnel between the donor SGSN and the recipient SGSN, or alternatively, the tunnel can exist for a considerably shorter time than the commonly used 20 seconds.

Abstract: A technique as well as associated systems, methods, and apparatuses for preventing an overflow of data packets at a plurality of nodes in a wireless data network is presented herein. The amount of available allocated memory at the plurality of nodes for a wireless client is monitored by a wireless content switch. The wireless content switch also intercepts a signal transmitted from the wireless client which indicates the amount of available memory at the wireless client. The wireless content switch modifies the signal such that the indicated amount of memory does not exceed the amount of memory allocated at the plurality of nodes for the wireless client.

Abstract: A system and method for seamless interaction between a wireless local network (WLAN) and a wireless packet data network is presented herein. A wireless content switch is placed between the WLAN and wireless packet data network. The wireless content switch authenticates the wireless clients of the WLAN and assists nodes in the wireless packet data in authenticating the wireless client.

Abstract: A system and method for establishing a server initiated data connection with a particular wireless client are presented herein. A wireless content switch is inserted into the wireless data service network and receives requests for data connections with particular wireless content switches from content servers. Responsive to receiving the request, the wireless content switch transmits signals to the wireless client causing the wireless client to request a data connection with the content server. During the processing of the request, the wireless network transmits a signal embedded with an address associated with the wireless client which is received by the wireless content switch. The wireless content switch transmits a signal which provides the address to the content server. Upon receiving the address, the content server transmits data with the foregoing address.
