Abstract: An apparatus and method for enhancing packet transfer in a network using duplicated copy of data packets are disclosed. Upon classifying a data packet in accordance with a set of predefined packet identifiers, the method for enhancing packet transfer, in one embodiment, generates a replicated packet which is substantially similar to the data packet in response to the result of classification of the data packet. The replicated packet is subsequently forwarded to an application component via a route of non-bearer traffic for facilitating parallel processing.

Abstract: A method, apparatus, system, and computer program for providing selective advertising. The method includes providing an advertisement request specifying that advertising content be provided and automatically providing the advertising content on at least one network service in response to the advertisement request. The advertising content provided is based upon advertising content preferences pre-specified by a subscriber. Also provided is a method for exchanging payments, which includes determining a payment payable to a network service provider from a subscriber and providing the payment to the network service provider from the subscriber. The payment is determined as a cost for access to a selective advertisement service and/or a provisioning of selective advertising.

Abstract: An integrated overlay card, an optical line terminal with an integrated overlay card, and a method for operating an optical network. The integrated overlay card may fit at least partially within the optical line terminal. The integrated overlay card includes a wavelength dimension multiplexer/demultiplexer that overlays first signals at a first wavelength onto second signals at a second wavelength, so as to combine signals. The combined signals may be routed to an optical network. In example embodiments, the invention may be used to provide an IP television service.

Abstract: A multi-access network terminal includes first and second communication interfaces. The first interface is configured to communicate with a first service provider providing services to a user through the first interface with a first type of signal and/or a first type of communications protocol. The second interface is configured to communicate with the first service provider providing services to the user through the second communication interface using a second type of signal and/or a second type of communications protocol. Alternatively, the second interface is configured to communicate with a second service provider providing services to the user through the second communication interface using the first or second type of signal and/or the first or second different type of communications protocol.

Abstract: When an optical network terminal (ONT) is rebooted, for example, after being upgraded, the ONT may be not be ranged and provisioned for some time. This may disrupt services, such as video services provided to a customer. As such, a method and corresponding apparatus of ensuring continuous receipt of video services based on certain conditions in a passive optical network (PON) are provided. The method may include detecting at a PON element a condition indicating a change of states in receipt of video services, starting a timing mechanism having a default value stored in the PON element, and enabling receipt of video services at the PON element for an amount of time defined by the default value. Receipt of video services is enabled by maintaining video services at a second PON element and sending the video services to the PON element. In this way, disruption to video services is reduced.

Abstract: Disclosed is a novel Packet Voice Gateway (PVG) that is adapted for the line side of the communication network, such as for example in a Digital Loop Carrier Terminal, which provides functionality that can effectively bridge service between a circuit switched based access network and a packet based public network. The ability to so bridge service using the PVG of the present invention allows service operators to extend their circuit switched capital investment by enabling such equipment to be used in connection with a packet based public network.

Abstract: In a multi-point mobile radio broadcast network, the multiple mobile radios can have personality information reprogrammed via a broadcast method, rather than on a one-to-one basis. A communications manager, which controls the communications between the various mobile radios can change the personality information contained in each radio by broadcasting that information to the radios as a group. After receiving the new personality information, a processor within the mobile radios can remove the unique identification codes associated with that particular radio from the old personality information, imported into the new personality information communicated to it by the communication manager, and store the new personality information with the newly incorporated unique identification codes into a local memory. The protocol for broadcasting the personality information to the mobile radios is important to ensure that the mobile radios receive the new personality information.

Abstract: An improved private radio communication system and method for routing data signals to multiple remote devices connected to a common remote receiver and for routing data signals to applications both within the remote devices and within the common remote receiver is disclosed.

Abstract: A mobile radio communication system is disclosed in which personality information for a radio can be modified in order to permit the radio to roam from one broadcast region to another. Since each broadcast region is serviced by a different gateway, the radios within that region use particular personality information in order to communication with it. When the radios roam from one region to another, the radios request new personality information relevant to the destination region. Each radio uses local identification data to uniquely identify the radio within the system. When the radio roams, the gateway provides the radio with new local identification data relevant to the destination region. The local identification data for each radio in a given region is mapped by the gateway in a memory such that available local identification data can be re-assigned to radios that roam into the gateway region.

Abstract: The present invention recovers data utilizing information from previously received data packets to reconstruct a data packet with an ever increasing probability of reconstructing the actually transmitted data packet. With each new reception, the accumulated information brings the receiver closer to obtaining the actually transmitted data packet. This use of information which might otherwise be discarded permits highly efficient and effective bit error correction particularly useful in hostile communications environments by transceivers with limited data processing and/or memory resources.

Abstract: A radio communication system having a host computer and at least one remote, mobile, two-way radio communicating with the host computer by exchanging data packets. A communication gateway between the host computer and the remote radios mediates the exchange and maintains an address table containing both the physical address and an internet address for the various components. The gateway translates between the physical and internet addresses, allowing more flexible communication between the various interconnected components.

Abstract: A digital radio has standardized "key" storage for several different cryptosystems (DES, VGE, VGS, etc.). Cryptographic keys are stored in a table in non-volatile memory such as EEPROM. The "keys" are stored in an "encrypted" form such that their identities are not readily revealed by a "dump" of memory contents. Additional security is provided in accordance with the present invention by extracting the "keys" from the stored table and re-"encrypting" the entire table each time a key loader device is attached to the radio. Multiple key banks are used to provide enhanced voice security by increasing the number of encryption keys available for use by a radio.
