A mobile station for transferring delay-sensitive data to a wireless communications network is provided with an uplink resource release controller that selectively inhibits release of an uplink resource in order to meet requirements of a delay-sensitive data application, such as a VoIP or streaming application. In one embodiment, the uplink resource release controller causes dummy blocks to be written to a data buffer to prevent initiation of a countdown process. By intelligently controlling resource release, delay-sensitive data may be transmitted in a more reliable fashion, thereby increasing application performance.

Architecture for playing back personal text-based messages such as email and voicemail over a vehicle-based media system. The user can use a cell phone that registers over a cellular network to an IMS (IP multimedia subsystem) to obtain an associated IP address. The personal messages are then converted into audio signals using a remote text-to-voice (TTV) converter and transmitted to the phone based on the IP address. The phone then transmits the audio signals to the vehicle media system for playback using an unlicensed wireless technology (e.g., Bluetooth, Wi-Fi, etc.). Other alternative embodiments include transmitting converted message directly to the media system, via a satellite channel, converting the messages via a TTV converter on the cell phone, and streaming the converted messages to the phone and/or the media system for playback.

Vehicle-based message control using cellular IP

A mobile station for receiving delay-sensitive data from a wireless communications network is provided with a data buffer and cell reselection controller. The data buffer receives data from the network and stores the data for communication to a delay-sensitive data application. The cell reselection controller selectively inhibits cell reselection in order to meet requirements of the delay-sensitive data application. By intelligently controlling cell reselection, delay sensitive data may be received in a more reliable fashion, thereby increasing performance of the data application.

System and method for providing intelligent cell reselection for delay sensitive data applications

A server subsystem is presented for mobile communication that provides for efficient and logical movement between applications on different servers. Multiple applications may be used simultaneously and interactively using the server system presented herein.

Dynamic event server subsystem utilizing session initiation protocol

The present invention provides systems, methods, and devices adapted to notify a communications network that an application is present on a communication device by sending a feature tag that identifies the application to the communications network. The communications network can register, re-register, or de-register an application with an application server in response to receiving the feature tag. The invention provides a method by which an application can be registered in accordance with a feature tag and satisfaction of predetermined registration conditions. A further method of the invention can include updating a presence server in response to receiving a feature tag. The systems, methods and devices of the invention facilitate registration of applications in way that conservers network resources and decreases signaling traffic over the air interface.

Systems and methods for delivering a converted message to a vehicle media system

An authentication and validation architecture utilizing a P-CSCF (proxy-call session control function) service to validate a source IP address against a registered contact IP address upon receiving an initial request for a dialog or a standalone request (except REGISTER) from a registered user. This provides a security measure to prevent IMS (IP multiemdia subsytem) identity spoofing, when SIP security (IPsec) access security is not enabled, or not used, between the user equipment (UE) and P-CSCF service.

User equipment validation in an IP network

The present invention is directed to a system and method for providing services, such as location-based services, in a GPRS network. In a preferred embodiment of the present invention, a database including local geographical information is stored in a BSS (Base Station System). The BSS transmits data in the database to at lease one MS on dedicated DPCHs in idle packet frames. The MS populates its database with the data while in idle mode and provides the location-based services to a subscriber using its database.

System and method for providing information services to subscribers in a GPRS network

A system and method for coordinating network operation modes of a GPRS network is disclosed. The system includes a database storing a preferred list of network operation modes of the GPRS network that a mobile subscriber registered for. A SGSN detects the status of an interface for GPRS packet data services and reports the status to a BSC. BSC in turn decides which network operation mode to use based on the preferred list. The GPRS network is then switched to the preferred network operation mode.

A system and method that provides remote access to nodes in a wireless telecommunication system comprises sending a first message from an operations node in the wireless telecommunication system to a packet interface. The first message may be dynamically directed to a first of the nodes in the wireless telecommunication system. This may be accomplished by dynamically directing the first message using an unallocated channel, using an allocated but inactive channel, using an active channel, or prioritizing the first message in the active channel.
