摘要： A system and method for controlling the flow of data from a data network to a mobile user over a wireless link. A data flow controller is provided in an inter-working gateway between the mobile switch center of the wireless network and the data network. The data flow controller determines the amount of available space in the mobile switch center buffer and ensures that the amount of data sent to the mobile switch center is no greater than the available buffer space. The data flow controller continually updates the available buffer space by determining the amount of data sent periodically to the mobile user according to a given airlink data rate. The data flow controller includes a buffer to store any remaining data that could not be sent to avoid overflowing the mobile switch center buffer.

摘要： A telephone system supports communication with user devices over both a cellular radio network as well as over an Internet Protocol (IP) network, and enables roaming and active call handoff between cellular and IP domains. Approaches to detecting presence of a user near a suitable IP network are used in controlling transitions between the domains, for example, enabling automatic transitions between domains, and delivery of calls to a mobile user to data network devices in the vicinity of the user.

摘要： An apparatus and method for routing data packet connection pathways. A pathway controller monitors all of the packet data service nodes available for the transmission of data packets to mobile nodes in order to allocate the service nodes appropriately. A main call processing node selects an available packet data service node for use for a mobile node based upon the availability of the service nodes. A mobile node may have its data packet pathway deactivated if the network infrastructure determines the need to free-up resources for other mobile nodes. The data packet pathway may be reactivated upon the event of a new data packet arriving for the mobile node. The methods of deactivation and reactivation may be used to solve data packet pathway serving faults. The data packet connection pathways that may be reactivated may be done in a load balanced fashion.
