20080293389Method and system of forwarding SMS messages - A method of forwarding messages in a wireless network is provided. The method comprises receiving a message destined for a first mobile station, processing the message based on call forwarding data to make a determination as to whether the message is to be forwarded to different mobile station, and transmitting the message to a message center responsive to the determination determining that the message is to be forwarded to a different mobile station.11-27-2008
20080305811STORING ACCESS NETWORK INFORMATION FOR AN IMS USER IN A SUBSCRIBER PROFILE - IMS networks and methods are disclosed for storing information on the access network of a user in a subscriber profile for the user. When a communication device of a user attempts to register with an IMS network, a P-CSCF receives a register request message from the communication device, and identifies access network information for the user. The P-CSCF then transmits another register request message to an S-CSCF that includes the access network information, and the S-CSCF in turn forwards the access network information to an HSS. The HSS then stores the access network information in the subscriber profile for the user. Nodes in the IMS network that retrieve the subscriber profile may acquire the access network information to provide services based on the access network information.12-11-2008
20090037540NOTIFICATION OF WAITING VOICEMAIL MESSAGES BETWEEN DIFFERENT TYPES OF COMMUNICATION NETWORKS - Systems and methods are disclosed that provide notification of waiting voicemail messages between different types of communication networks. A first communication network as described herein includes a voicemail server to store voicemail messages for a user of a communication device. A second communication network provides phone service to the communication device but uses a different signaling protocol than the first communication network. In order to notify the user of the waiting voicemail message in the voicemail server, a subscriber server (e.g., an HLR) in the first communication network receives a voicemail waiting indicator in the signaling protocol of the first communication network, identifies the signaling protocol of the second communication network, and converts the voicemail waiting indicator to the signaling protocol of the second communication network. The second communication network may then provide notification of the waiting voicemail message to the user.02-05-2009
20100003971REPEAT DIALING IN WIRELESS NETWORKS TO BUSY CALLED PARTIES - A wireless network is disclosed that provides repeat dialing to busy called parties. The wireless network includes an originating MSC system that serves a calling party, and a terminating MSC system that serves a called party. The calling party initiates a call to the called party through the originating MSC system, and the terminating MSC system determines that the called party is busy on another call. The originating MSC system then receives a repeat dialing instruction from the calling party and transmits a repeat dialing indicator to the terminating MSC system. The terminating MSC system identifies when the called party becomes available in substantially real time. When available, the terminating MSC system attempts to set up a call between the called party and the calling party.01-07-2010
20100009701METHOD AND APPARATUS FOR DATA MESSAGE DELIVERY TO A RECIPIENT MIGRATED ACROSS TECHNOLOGY NETWORKS - A method of providing SMS delivery to recipients migrated across different technology networks. The method includes receiving a short message service (SMS) text message from a sender at a short message service center (SMSC), wherein the SMS text message includes a destination number for a recipient of the SMS text message. A first routing request is sent to a database in a first network for SMS routing information for the destination number via a first signal transfer point (STP). The first STP determines whether the destination number is a migrated or a non-migrated destination number based on data received from the first database. An an error indication is provided to the SMSC if the destination number and the first routing request are for different communication networks. Finally, a second routing request is sent to a second database in a second network for SMS routing information for the destination number via a second STP.01-14-2010
20100267382REPEAT DIALING IN WIRELESS NETWORKS TO CALLED PARTIES THAT ARE POWERED OFF - A wireless network is disclosed that provides repeat dialing to called parties that are powered off. The wireless network includes an originating MSC system, a Home Location Register (HLR) system for a called party, and a serving MSC system that serves the called party. Responsive to identifying that the called party is powered off, the calling party transmits a repeat dialing instruction to the originating MSC system. The originating MSC system then transmits a repeat dialing indicator to the HLR system for the called party. The HLR system for the called party identifies when the called party powers on. When the called party does power on, the HLR system transmits an instruction to the serving MSC system to attempt to set up a call between the called party and the calling party.10-21-2010

20090268749ENHANCED CMTS FOR RELIABILITY, AVAILABILITY, AND SERVICEABILITY - A Cable Modem Termination System (CMTS) is partitioned into Line Cards, I/O Cards, and a midplane to provide enhanced Reliability, Availability, and Serviceability. Each I/O Card provides a cabling interface for coupling an assigned Line Card to other portions of a Hybrid-Fiber-Coax Network. A plurality of RF signals is coupled via connectors between each Line Card and a corresponding I/O Card, via the midplane. This permits a Line Card to be removed for servicing without requiring recabling of the corresponding I/O Card. Preferably, a rectangular-multi-pin collinear connector-cascade (Line Card jack, midplane double-plug, and I/O Card jack) is used to couple the plurality of RF signals. The connector-cascade is configured with protective RF ground pins adjacent and surrounding each of a plurality of RF signal pins. This approach permits each Line Card to be removed or inserted in a single action, without attention to individual RF interconnects, yet meets all system RF requirements while using relatively inexpensive connectors. The I/O Cards preferably include a distributed backup bus that permits one of the Line Cards in the CMTS to serve as a designated backup. The backup bus enables assignment of the designated backup Line Card to the I/O Card associated with a failing Line Card, without requiring recabling of any I/O Card. In conjunction with a signal processing architecture that permits dynamically programmable channel assignments, the backup bus facilitates rapid and fully automated failover. The Line Cards are preferably further partitioned into easily replaceable sections, including IF-to-RF and signal processing modules.10-29-2009
20100031305ENHANCED FIBER NODES WITH CMTS CAPABILITY - Enhanced Cable Modem Termination System (CMTS) functionality, including programmable digital domain modulators and demodulators for dynamic channel assignment, is incorporated into Fiber Nodes (FNs) or mini Fiber Nodes (mFNs), yielding enhanced Fiber Nodes (eFNs). These eFns distribute CMTS functionality deep into Hybrid-Fiber-Coax Networks (HFCN) rather than centralizing the CMTS functions within a single location. Moving the cable modem terminations closer to the subscribers shortens the analog RF paths required to support cable modems. Communication of both subscriber data and CMTS control data is performed over Ethernet-compatible packet networks between the field-based CMTSs and an upstream facility (e.g., the Head End), which includes an Internet gateway. Packet data for multiple subscriber cable modems is easily compressed and merged over common network paths, reducing cabling plant complexity and increasing bandwidth utilization. This approach dramatically reduces the infrastructure cost per cable modem. Distributing CMTS functionality among multiple eFNs also reduces demands on already stretched resources at the Head End for space, power, and HVAC. For HFCN channels containing signals with modulation or encoding schemes that are unknown or best processed upstream, the invention also provides for tunneling their spectrum over the same packet network as used for the cable modem data. The channels to be tunneled are isolated using digital receivers, translated to baseband, their data framed, merged with cable modem subscriber data, and transmitted over the packet network. Upstream, the framed channel data is parsed and the original channel spectrum reconstructed to permit information recovery.02-04-2010
