Abstract: A method and system for performing adaptive compression in a wireless communication network includes monitoring a link quality of a signal transmitted via an air interface using, for example, a telecommunications node. Next, it is determined whether the link quality deteriorates below a first link quality threshold. A compressor associated with the transmitted signal is disabled in response to a determination that the link quality has deteriorated below the first link quality threshold.

Abstract: An interfacing method and Virtual Internet Protocol (VIP) Framework that provides high fault tolerance and linear scalability of servers and network interfaces. The Framework has minimal impact on the surrounding network infrastructure. The preferred embodiment operates at the IP level, thus enabling the Framework to operate with any application that runs on top of IP. Incoming data packets and packet fragments are received from the Internet in a plurality of network terminations. Routing processes provide external routers with addresses of the network terminations. Each network termination is associated with one of a plurality of forwarding processes, and each forwarding process is connected to a plurality of fragmenter/de-fragmenters. Each forwarding process selects a single fragmenter/de-fragmenter to receive all of the incoming data packets and packet fragments having a common source address.

Abstract: A Radio Network Server (RNS) is modified to function as a policy server providing radio network resource allocation rules in an integrated third generation wireless IP network. The RNS determines a level of availability of radio network resources, and determines whether the level is sufficient to satisfy requests for resources in accordance with policy rules. The RNS informs a Bandwidth Broker (BB) whether the radio network resources are available. The BB functions as a Policy Decision Point (PDP) for its domain, and either allows or denies requests from users for network resources based on the input from the RNS. A plurality of edge routers in each domain interface with the BB utilizing the Common Open Policy Service (COPS) protocol interface. The edge routers function as Policy Enforcement Points (PEPs) for their domain to enforce policy decisions made by the BB. The BB may interface with BBs in other domains for calls that span multiple domains.

Abstract: Routing nodes that are interconnected within a communications network are not configured to utilize a single type of switching technology in the context of a single type of networking topology. Responsive to data input and the operation of an expert system, the routing nodes are configured to implement a certain switching technology type and networking technology type, and thus optimize portions of the communications network to handle different types of traffic. Traffic of the various different types may then be efficiently handled through the network by its correspondingly optimized portion.

Abstract: A method and system for increasing compatibility among telecommunications networks using different types of signaling systems. Current location information for a mobile station is stored in a register. Subsequently, a telecommunication node attempting to access the mobile station requests current location data from the register. It is determined, however, that the stored location information is incompatible with a signaling system used by the telecommunication node. As a result, a physical address that corresponds to the stored location information is identified as being compatible with the signaling system. The identified physical address is then used to perform the access of the mobile station. In accordance with one embodiment of the invention, the attempted access of the mobile station is for purposes of delivering a short message service (SMS) message. In another embodiment, the attempted access comprises an attempt to set up an international call connection.

Abstract: In a cellular telecommunications network, a method and system allowing a Message Center (MC) to receive an indication of the periodic broadcast SMS capability of co-operating Mobile Switching Centers (MSCs) when a periodic broadcast SMS is initiated. According to the invention, when a periodic broadcast SMS request is sent from an MC to one MSC for broadcast to the Mobile Stations (MSs), the MSC detects its own capability to handle the periodic broadcast SMS request. Therefore, an indication of the MSC's capability is sent back to the MC. If the MSC accepts to handle the periodic broadcast SMS request on its own, the MSC records the message and periodically broadcasts it to the destination MSs. If not, the MC periodically sends a regular broadcast SMS request along with an instruction for delivery to the MSC, which in turn forwards the SMS body message to the destination MSs.

Abstract: In the context of a completed inter-exchange handoff of a mobile station communication, an anchor exchange may request certain call related information from a currently serving exchange. This request is made through use of an inter-exchange information request message issued from the anchor exchange and sent (perhaps through one or more tandem exchanges) to the serving exchange. Responsive thereto, the serving exchange processes the request, obtains the requested call related information, and returns the requested information in an inter-exchange information request return result message. The information request message may comprise a newly defined ANSI-41 message, a vendor proprietary extension to the ANSI-41 message set, or an enhancement to an existing ANSI-41 message.

Abstract: A system, method, and apparatus for providing subscriber services to a mobile terminal are provided. The mobile switching centers (MSCs) transmit an MSC capabilities message which informs the Home Location Register (HLR) of the services the MSC supports. When a mobile terminal roams to a particular MSC, the HLR compares the subscriber profile and the MSC capabilities message to determine whether the MSC can support a particular subscriber service. Where the MSC cannot support a particular subscriber service, the HLR determines a comparable service which the MSC does support and modifies a copy of the subscriber profile to include the comparable service as a replacement for the subscriber service that is not supported.

Abstract: Control is exercised over a tap connection made for law enforcement agency monitoring of mobile station communications in response to an inter-exchange hand-off. Where such a tap connection does not yet exist at hand-off, pre-hand-off actions taken at the target exchange trigger an analysis of whether a party to that communication is marked for monitoring followed by an establishment of the tap connection at hand-off if the party is so marked. If the tap connection is already in place, pre-hand-off actions taken at the target exchange trigger an analysis of whether law enforcement agency monitoring of that communication is lawfully authorized with respect to the target exchange followed by instructing the anchor exchange to terminate the tap connection at hand-off if monitoring is not lawfully authorized.

Abstract: A method and system for automatically adjusting charges to a pre-paid account in a telecommunications or distributed processing network following a failure in the network. After a service that is chargeable against the pre-paid account is initiated in the network, a failure in the network is detected. The failure prevents a charging node from receiving event data relating to the pre-paid account. After recovery from the failure, a message is sent to the charging node containing service status information. The charging node adjusts the account balance in accordance with the service status information.

Abstract: An integrated radio telecommunications network which integrates an ANSI-41 circuit switched network and a General Packet Radio Service (GPRS) packet data network to support a mobile station which operates in both the ANSI-41 network and the GPRS network. An interworking function interfaces a mobile switching center (MSC) in the ANSI-41 network with a serving GPRS switching node (SGSN) in the GPRS network by mapping circuit switched signaling utilized by the MSC into GPRS packet switched signaling utilized by the SGSN, and mapping GPRS packet switched signaling into circuit switched signaling. An interworking GPRS base station controller interfaces the SGSN with a GPRS/ANSI-136 base station which supports both ANSI-136 operations and GPRS operations. The interworking GPRS base station controller adapts the traffic signaling format utilized by the SGSN into an air interface traffic signaling format utilized by the GPRS/ANSI-136 base station.

Abstract: A method of supporting functionality for roamer port calls in a radio telecommunications network in which Number Portability (NP) is implemented, the network having a plurality of mobile switching centers (MSCs) and home location registers (HLRs). The network includes a roamer port MSC having a roamer port which is shared with at least one neighboring MSC. A number portability database (NPDB) associates a location routing number (LRN) with each distinct MSC/HLR pair in the network. When a roamer port call, which includes the mobile directory number (MDN) of the called mobile station, is received in the roamer port MSC, the roamer port MSC determines whether the MDN falls within a ported range. If so, a request is sent to the NPDB to retrieve a LRN for the called mobile station. From the LRN, a HLR associated with the mobile station is identified.

Abstract: The present invention is a method and system for managing frequencies allocated to a cell within a cellular network to assign certain ones of those allocated frequencies for use by channel equipment within that cell. The method measures at least one quality metric for each of the allocated frequencies. At least one measured quality metric for the unassigned frequencies are compared against at least one quality metric for the assigned frequencies. An unassigned frequency is swapped for an assigned frequency based upon the comparison step. Additionally, a voting step is used to indicate that either the unassigned frequency or the assigned frequency has a higher signal quality for communication.

Abstract: A method and apparatus for generating a billing identifier for a subscriber from a first network roaming within a second network is disclosed. A node interconnecting the first and second networks receives a call message that does not include a billing identifier from the first network. A billing functionality within the node responsive to the call message generates a billing identifier enabling billing records within the second network to be associated with the subscriber from the first network. Messages containing the billing identifier are then transmitted to the second network from the interconnecting node.

Abstract: A system and method of reducing control message signaling load in a radio telecommunications network. When an authentication request is issued by the mobile switching center (MSC), the home network performs authentication of the visiting subscriber. When authentication fails the home network determines if a threshold value is reached. If so, a suitable authentication code portion is included in the return message so that local authentication of the visiting subscriber may be performed. The MSC is able to locally authenticate a visiting subscriber trying to access the network thereby suppressing the transmission of additional authentication requests and failure reports to the home network. For failed authentications, the VLR transmits authentication failure reports to the home network. If a threshold value is reached the MSC locally authenticates the mobile subscriber's subsequent attempts so that the VLR is precluded from sending additional authentication failure reports to the home network.

Abstract: A system and method of transferring data to and from a mobile station (MS) in a cellular telecommunications network. When the MS originates a data transmission, the MS simultaneously seizes additional voice channels or control channels from the serving cell or adjacent cells, fills time slots with data packets, and asynchronously transmits the data packets over the plurality of channels in order to increase the data transfer rate. For data calls terminating at the MS, the serving mobile switching center (MSC) reserves a plurality of channels having sufficient signal strength to maintain a connection with the destination MS. The MSC informs the involved base stations that an asynchronous transmission is to be made to the MS. The MSC then assembles the data packets and starts transmission through the involved base stations to the MS over the reserved channels. The MS assembles the packets in numerical order and delevers the data to the user.
