Abstract: A method and system is provided for periodically and dynamically updating allocation pools of IP address which are reserved for wireless or wireline hosts. A system IP address server controls an entire address pool, contains predictive analysis logic, performs a predictive analysis, partitions the IP addresses into distinct address pools, and maintains “wireless guard bands” of IP addresses for wireless users to ensure that a higher priority address pool is never exhausted before an address pool which has a lower priority.

Abstract: A technique for assigning an address (“shadow address”) to a mobile station that is compatible with the layer-2 address on the wireline network which serves the mobile station. The shadow address is then used as a wireline identifier for the destination address for frames ultimately destined for the mobile station. The shadow address is stored in a watch list for serving base stations, and any base station receiving a frame with a shadow address in its watch list process the frame to forward it the to mobile station. In this way, the shadow address facilitates carrying out soft handoff and smooth handoff.

Abstract: The present invention relates generally to logical telephone numbers. In particular, dynamic number users are able to obtain dynamic numbers and to map those numbers to routable numbers of their choosing. The present invention provides a tool for protecting privacy while sharing and/or publicizing a number for public purposes. The present invention relates to a Dynamic Telephone Number Service (DTNS.) wherein users are provided with a logical temporary telephone number that is mapped dynamically to a physically addressable number. The use of the DTNS allows a dynamic number user to publish the logical number, thus avoiding the need to publish private information and phone numbers for public purposes. Further, the logical number is not permanently assigned, but rather is temporary and provided to the dynamic number user for a relatively short period of time.

Abstract: A Bluetooth-enabled terminal having a radio manager for minimizing frequency collisions between channel hopping patterns transmitted over plural channels established between such terminal and correspondent Bluetooth devices is described. The radio manager extracts successive sets of projected future N—time slot segments of the respective Bluetooth channel hopping patterns. Each extracted set is tested to detect a time slot, if any, where frequency hops of the segments of the set coincide, indicating a frequency collision. When a collision time slot is detected, the radio manager generates a marker which triggers an alteration of the frequency hops that would otherwise be exhibited by a subset of the generated channel hopping patterns in such detected time slot. Such terminal may optionally be provided with an additional network interface to define a collision-resistant Bluetooth access point.

Abstract: A method is provided for IP-based wireless networks to support dynamic assignment of IP addresses to wireless mobile stations without broadcasting messages over the air and without modifications to standard IP for dynamic IP address assignment. When a mobile station enters a new cell, it sends a request to the base station for a new IP address. At the base station, DHCP proxy servers intercept and process broadcast DHCP messages so they are transmitted only to the address server and are blocked from being sent to the other base stations in the wired IP Network for broadcast to other mobile stations. When the address server creates a server-to-client message with the requested address and places it on the wired IP Network, DHCP proxy servers at the base stations convert the broadcast DHCP messages to unicast messages for transport over the air to only those mobile stations that are currently requesting new IP addresses or verifying their current IP addresses.

Abstract: Method, system, and circuitry for successfully completing soft handoff in an Internet Protocol (IP) based autonomous base station wireless Code Division Multiple Access network, wherein processing is done at the serving base station so that target base stations need only set up the channel for transmitting the copied data needed for soft handoff. Concomitant circuitry comprises packet data multiplexers/assemblers and demultiplexers/de-assemblers for performing cross-layer switching. Data packets are sent by a serving base station to a mobile unit while the mobile is in a soft handoff region. The serving base station also sends copies of the data packets to target base stations, the target base stations in turn relay these data packets to the mobile. The mobile synchronizes the copies of the data packets received and combines the packets to recover the data.

Abstract: Methods and systems are provided for facilitating intra-domain mobility. A first network or domain includes a home agent or SIP proxy of a mobile node. A second network includes two or more subnetworks and at least one dynamic tunneling agent (DTA). Each subnetwork includes an associated subnet agent. To communicate, the mobile node first registers with a subnet agent, receives a local care-of-address and a global care-of-address, and then registers with a DTA. The local care-of-address received from the subnet agent may enable communication with the mobile node without determining a specific route to the mobile node. The global care-of-address received from the subnet agent may include the address of the DTA with which to register. On registering with the DTA, the DTA may provide the mobile node with a unique, globally reachable global care-of-address, which the mobile node may then forward to a home agent, SIP proxy, or a correspondent node.

Abstract: Methods and systems are provided for facilitating intra-domain mobility. A first network or domain includes a home agent or SIP proxy of a mobile node. A second network includes two or more subnetworks and at least one mobility agent (MA). Each subnetwork includes an associated subnet agent. To communicate, the mobile node first registers with a subnet agent, receives a local care-of-address and a global care-of-address, and then registers with an MA. The mobile node may then provide the global care-of-address to the home agent. The local care-of-address may enable communication with the mobile node without determining a specific route to the mobile node. The global care-of-address received from the subnet agent may include the address of the MA.

Abstract: Method for selecting IP data packet segments in an all-IP architecture that supports CDMA soft handoff via IP multicasting, wherein both the mobile terminal and IP backbone network receive a plurality of identical, redundant CDMA IP data packets. A best IP data packet is created by first, receiving a plurality of IP data packets from a plurality of corresponding base stations, second, separating those IP data packets into data packet segments comprising separate time intervals, and third, employing different metric standards to determine which of those data packet segments received for each time interval is the best data packet segment. The best data packet segments are determined by creating a quality matrix that represents the quality of each data packet segment for each time interval. A quality function is then computed for each time interval to determine which data segment is the best for that particular time interval.

Abstract: Method and apparatus to generate a dynamic contact list of contact and presence information about contact events in a communication system when a calling entity unsuccessfully attempts to communicate with a called entity. When such a contact event occurs, a routing processor or call agent generates contact information about the contact event, including the calling party, called party, time of the contact event, and purpose of the contact event. A presence management processor also generates the presence information about the calling party's subsequent availability for return communication, including if a calling party is available for return communication, when the calling party is available for return communication, how long the calling party is available for return communication, and how the calling party is available for return communication.

Abstract: Processing of multimedia calls in a packet-based network builds on existing call model processing by maintaining the use of the basic call state models to control the overall two-party call and the use of connection views to associate multiple two-party calls and provide access to advanced supplementary services. Through the use of a multimedia view processor, the system separates multimedia connection handling from call handling. The basic call models are extended to support new messages and enhanced messages for creating, modifying, and deleting multimedia view objects and communicating modifications to the media streams between call state model processors and protocol specific processors.

Abstract: A service architecture for the rapid development of next generation telephony services that overcomes the limitations of the current closed PSTN architecture and service model. In this architecture services are provided by multiple cooperating distributed service providers. This architecture is built upon an object-oriented call model which is defined as a small set of extensions to the standard Java Telephony API call model. This new object-oriented call model hides the detail of the underlying call-state management protocols and hardware from applications.

Abstract: A method and system for dynamic forward assignment of IP addresses in a wireless network wherein a serving base station requests IP addresses of it neighboring cells. The serving base station then provides the requested IP addresses to the mobile stations it serves based on whether the mobile station will be entering a particular neighboring cell. Immediately upon entering the neighboring cell the mobile station establishes over the air communications with the neighboring cell's base station using one of the requested addresses. In another embodiment of the present invention each mobile unit is responsible for attaining IP addresses from the base stations of neighboring cells. Accordingly, the base stations serve as relay points for the IP address requests from the mobile unit to an address server.
