Abstract: 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.

Abstract: A method of processing short message service (SMS) calls for a subscriber's communication device in a communication network is provided. The method comprises: receiving an SMS request involving the communication device at a short message service center; accessing a family access control database storing family access control information received for the communication device; and determining whether the short message service request should be allowed or denied based on the information found in the database.

Abstract: Systems and methods are disclosed that allow for storing of data messages (e.g., text messages or multimedia messages) in a data message mailbox. If a data message is sent from a sender to a recipient, then the communication network receiving the data message attempts to deliver the data message to the recipient. If unsuccessful in delivering the data message, then the network stores the data message for the recipient. If the communication network later receives a request to retrieve the stored data message from the recipient, then the communication network delivers the stored data message to the recipient.

Abstract: SMS messages are delivered to non-SMS devices (e.g., wireline devices in legacy communication networks). Upon receiving an incoming SMS message, a message application server (e.g., SMSC) can detect, based on the directory number of the destination terminal, whether the destination terminal is a non-SMS device. If the destination terminal is a non-SMS device, the SMSC initiates delivery of the SMS message according to a delivery profile appropriate to the destination device. Exemplary delivery profiles include a spoken text message format, an ISUP-compatible text format or a caller ID message format.

Abstract: This invention provides an innovative way of providing voice and data registration of multimode (voice and data) handset subscribers at a common place. The unified subscriber data server provides a flexible mechanism to provide concurrent registration for voice and data on the same platform, to store the subscription data (for voice and data subscribers) at a common place, and to perform call-processing either on the same box where the data is stored.

Abstract: Communication networks and methods are disclosed that provide call forwarding between different types of wireless networks. If a wireless device is being served by a first wireless network and a call is initiated in a second wireless network, then a common or shared subscriber server is used to provide call forwarding. If a call forwarding condition (e.g., a busy condition or no answer condition) is detected in the first wireless network, then the first wireless network transmits a first call forwarding request message to the subscriber server. The subscriber server converts the first call forwarding request message in a first messaging protocol to a second call forwarding request message in a second messaging protocol. The subscriber server then transmits the second call forwarding request message to the second wireless network, and the second wireless network initiates forwarding of the call responsive to the second call forwarding request message.

Abstract: Message spoofing is detected by an anti-spoofing application comparing a trusted switch address (i.e., corresponding to an originating switch having processed an incoming message) to an “affiliated” address (i.e., corresponding to a switch serving the location of the identified sender). Message spoofing is detected if the trusted address differs from the affiliated address.

Abstract: Systems and methods are disclosed that determine whether a sender/recipient using an electronic messaging service (e.g., SMS messaging service or MMS messaging service) is located in a defined home zone. A communication network in one embodiment includes a messaging system, such as an SMSC or an MMSC, and a home zone system. If the messaging system receives an electronic message from a sender to a recipient, then the home zone system determines a location of the sender/recipient. The home zone system also determines whether the sender/recipient is located in a home zone. If the home zone system determines that the sender/recipient is located in a home zone, then the messaging system forwards the electronic message to the recipient. If the home zone system determines that the sender/recipient is not located in the home zone, then the messaging system blocks the electronic message.

Abstract: Systems and methods are disclosed for selecting a preferred foreign wireless network from a plurality foreign wireless networks. One embodiment of the invention comprises a home wireless network that includes an HLR and a managed roaming system coupled between the HLR and a plurality of foreign wireless networks. The managed roaming system receives registration messages for roaming subscribers being transmitted from the foreign wireless networks to the HLR. The managed roaming system monitors the number of registration messages received from the foreign wireless networks and forwards the registration messages to the HLR. The managed roaming system selects a preferred foreign wireless network based on the number of registration messages received from the foreign wireless networks over a time period. The managed roaming system then forwards subsequent registration messages from the preferred foreign wireless network to the HLR, and blocks registration messages from non-preferred foreign wireless networks.

Abstract: Communication networks and methods are disclosed that provide call delivery to a dual mode wireless device served by a wireless data network (e.g., WiFi/IMS network) and a wireless voice network (e.g., cellular network). A call control function in the wireless data network is adapted to receive a call to the dual mode wireless device. The call control function transmits a ping message to the dual mode wireless device over the wireless data network to determine if the device is available over the wireless data network for the call. If the call control function receives a response to the ping message from the device, then the call control function attempts to set up the call over the wireless data network. If the call control function does not receive a response to the ping message, then the call control function may attempt to set up the call over the wireless voice network.

Abstract: Systems and methods are disclosed that control whether a recipient of an electronic message (e.g., text messages, multimedia messages, email messages, etc) is allowed to forward the electronic message to third parties. When an electronic message is created or selected for transmission to a recipient, a forwarding control indicator is included in the electronic message. The forwarding control indicator indicates whether this electronic message is allowed to be forwarded by the recipient. If the recipient of the electronic message subsequently attempts to forward the electronic message, then the forwarding control indicator is processed to determine if the electronic message is allowed to be forwarded. If a determination is made that the electronic message is not allowed to be forwarded to the third party, then the electronic message is prevented from being forwarded to the third party.

Abstract: This invention relates to a method and apparatus for blocking spam messages originated in a different network. An anti-spam check is made in response to an initial Send Routing Information (SRI) message received in a destination network of a message. The result of this check is sent back to the originating network along with a destination address of a switch in the destination network, and SRI spam code and Mobile Terminated (MT) Routing Address Correlation ID. If SRI spam code indicates a spam, then subsequent transmission of the MT message with the same Correlation ID is blocked in the interworking switch or SMSC.

Abstract: Communication networks and methods are disclosed that provide call delivery to a dual mode wireless communication device served by a wireless data network (e.g., an IMS/WiFi network) and a wireless voice network (e.g., cellular network). A common subscriber database includes subscriber data for the dual mode device. A call received to the dual mode device is routed to a call control function in one of the wireless networks. The call control function then queries the common subscriber database to determine in which network the dual mode device is currently registered. The call control function then routes the call to the dual mode device through the proper network.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A wireless network that provides notify me service for calls directed to called stations not currently registered on a network. A wireless network includes a network interface that serves a call from a calling station, and a called station network that serves a called station. The calling station initiates a call to the called station through the network interface to the called station network. The called station network determines that the called station is not currently registered on the network. Responsive to the called station not being registered, the network interface receives a notify me dialing instruction from the calling station and transmits a notify me dialing indicator to the called station network. The called station network determines when the called station registers, and transmits an indication for receipt by the calling station that the called station is registered.

Abstract: 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.
