Abstract: A system and method of accessing services from end terminals disposed in an integrated telecommunications network having a packet-switched network (PSN) portion such as, for example, a network portion using the Internet Protocol (IP) and a circuit-switched network (CSN) portion such as, for example, a wireless telephony network portion. A generalized service invocation and realization architecture includes one or more call control modules modified to include service-related Detection Points (DPs), a Service Access component or instance that is created when a new DP is encountered, and one or several service proxies which invoke services on behalf of the Service Access component and mediate between the call control modules and services. A common Service Logic Environment is implemented for local services, mobile agent services, and remote services. The PSN portion is preferably realized as a Voice-over-IP (VoIP) network having a gateway connected to the CSN portion.

Abstract: A system and method in a General Packet Radio Service (GPRS) network for automatically configuring Network Service Entity Identifiers (NSEIs) in a Base Station System (BSS) and a Serving GPRS Support Node (SGSN) when the BSS is reconfigured. The Gb interface between the BSS and the SGSN is modified to operate using the Internet Protocol (IP), and the BSS and the SGSN are configured to run on IP. Whenever a new Network Service Entity (NSE) is added to an existing BSS, or a new BSS is added to the network, the BSS automatically sends a modified Network Service (NS?)-Reset message to the SGSN requesting an NSEI. The SGSN dynamically allocates a free NSEI from a pool of NSEIs and sends it to the BSS. When an NSE is removed from the BSS, the BSS automatically sends a modified NS?-Reset message to the SGSN to free an NSEI. The SGSN de-allocates the NSEI, and returns the NSEI to the pool of free NSEIs.

Abstract: A method of monitoring a call with a mobile terminal (MT) in an Internet Protocol (IP)-based network having a Gatekeeper that controls the network, a plurality of access routers that provide access to the network, and a Monitoring Station having monitoring facilities and a database of MTs to be monitored. When the MT sends an Admission Request message to the Gatekeeper, the Gatekeeper sends a query to the Monitoring Station asking whether the MT is to be monitored. The Monitoring Station sends a reply to the Gatekeeper indicating that the MT is to be monitored and providing an IP address where monitored packets are to be sent. The Gatekeeper then sends a monitoring request message to the access router associated with the MT. The request identifies the MT to be monitored, instructs the access router to monitor the MT, and provides a unique call identification (Call ID) and the IP address where monitored packets are to be sent.

Abstract: A method in a Code Division Multiple Access (CDMA) 2000 packet data network of negotiating reporting mechanisms for accounting records, and sending accounting records from a Packet Data Service Node (PDSN) to an accounting server such as a Home Radius Server utilizing the Radius protocol. The PDSN sends an Access Request (AR) message to the accounting server, via any intermediate nodes, and includes (a) an Accounting Capability (AC) attribute indicating that the PDSN can accumulate a plurality of accounting records and send the accumulated accounting records in a container in a single message, and (b) an Accounting Handling (AH) attribute indicating a plurality of alternative reporting methods that trigger the PDSN to send a container. The Home Radius Server then sends an Access Accept (AA) message to the PDSN that (a) confirms that the Home Radius Server can receive accounting records in containers, and (b) indicates a preferred reporting method for triggering the PDSN to send a container.

Abstract: A Packet Core Function (PCF) and method of consistently selecting a Packet Data Service Node (PDSN) from a plurality of PDSNs in a packet data network to host a data session for a Mobile Node (MN). In a first embodiment, a static lookup table in the PCF is used to associate a list of identifiers for MNs and a list of the plurality of PDSNs in the network. The PCF obtains an identifier for the MN and utilizes the lookup table and a hash function to associate the identifier for the MN with a PDSN. The PDSN is then selected by the PCF to host the data session for the MN. In another embodiment, the PCF also includes a cache timer and a cache memory that stores the identifier for the MN and the IP address of the selected PDSN for a predetermined time period following the handoff of the MN to another PCF. If the MN returns to the PCF within the predetermined period of time, the PCF reselects the same PDSN to host the data session.

The MT then utilizes a Dynamic Host Configuration Protocol (DHCP) server in the MT to distribute the plurality of unique individual IP addresses to the plurality of devices on the LAN. In a second embodiment, the MT requests a separate PDP Context for each device on the LAN requiring an IP address. The MT utilizes a Point-to-Point Protocol over Ethernet (PPPoE) session between the devices on the LAN and the MT to virtually separate the physical network connection and distribute individual IP addresses to the plurality of devices on the LAN.

Abstract: A method in a 3G.IP network of routing a call from an originating subscriber in an originating network to a mobile terminating subscriber roaming in a visited network, the mobile terminating subscriber having a home network that maintains location information for the mobile terminating subscriber. When the originating subscriber sends a call origination message to a gatekeeper in the originating network, the gatekeeper obtains location information from the home network for the mobile terminating subscriber. An IP address of a media gateway in the visited network (MGW1) is then obtained and provided to a media gateway in the originating network (MGW2). The IP address of MGW2 is then sent to the originating subscriber. Thereafter, the call is routed from the originating subscriber through MGW2 in the originating network directly to MGW1 in the visited network. An MSC Server in the visited network then routes the call to the mobile terminating subscriber.

Abstract: A self-configurable system and method in a cellular telecommunications network for efficiently paging for mobile stations that last registered in a particular cell by automatically adjusting the size of an initial paging area on a per-cell basis. A plurality of sets of cells surrounding the particular cell are identified as Paging Depths (PDs) and are stored in a lookup table in a serving Mobile Switching Center (MSC). The PDs contain varying numbers of cells, and a first PD is selected to utilize for the particular cell's initial paging area. A plurality of paging attempts are then performed for mobile stations that last registered in the particular cell, and a statistical processor compiles statistics regarding the paging efficiency (percentage of mobile stations found versus total system resources used) and the success rate (percentage of paging attempts that were successful at locating mobile stations within the first PD).

Abstract: A method in a Wireless Intelligent Network (WIN) of handling subscriber services when a serving Mobile Switching Center (MSC) does not support all WIN triggers. The WIN includes a Home Location Register (HLR) having a subscriber profile that indicates the WIN triggers required to support a particular subscriber's active services. When an invoke message is sent from the MSC to the HLR, a WIN Capabilities (WINCAP) parameter is included and indicates the WIN triggers supported by the MSC. The HLR identifies a Service Control Point (SCP) for each subscriber service that requires a WIN trigger and is not supported by the MSC. The HLR then queries each identified SCP for call-treatment instructions. If an SCP determines that its service is essential, a response is returned to the HLR with an instruction to deny service to the subscriber.

Abstract: A system and method of providing high-speed wireless local loop access using a wireless access multiplexer disposed in an access network coupled to a plurality of network termination (NT) nodes. The access multiplexer is coupled via an aggregate path to a Point of Presence (POP) switch on a common carrier running at a high aggregate bit rate. A Network Management System (NMS) is provided with a database for storing service subscription profiles for subscribers associated with corresponding NT nodes. The subscription profiles include information regarding subscribers' bandwidth requirements and other Quality of Service (QOS) parameters as per their subscriptions. Using the Label Distribution Protocol (LDP) messages and procedures, the access multiplexer establishes a plurality of wireless access channels to the corresponding network termination nodes based on the service subscription profiles stored in the NMS.

Abstract: A system and method for interactively selecting call treatment in real time for an incoming call in a radio telecommunications network. A modified mobile station includes a display, a browser application that presents call information regarding the incoming call and call-treatment options on a pop-up menu the display, a keypad for a user to select a call-treatment option, and a Client Access Function Teleservice (CATS) handler that packages the selected call-treatment option in an IS-136 R-DATA message and sends the R-DATA message to a modified mobile switching center (MSC). The MSC determines that the R-DATA message is a CATS message from the value of the Higher Layer Protocol Identifier (HLPI) in the R-DATA message, and sends the call-treatment option to a modified service node in a short message service (SMS) message.

Abstract: A system and method in a radio telecommunications network for interactively providing a calling party with a choice of call handling options when a called mobile station (MS) is either busy or inactive. When a call is received for the called MS in the network, a home location register (HLR) determines the status of the called MS (i.e., whether the called MS is available, inactive, or busy). If the called MS is inactive or busy, the status is sent to a service control point (SCP) which generates a plurality of call handling options based upon the determined status of the called MS. The call handling options are provided to the calling party in an interactive prompting process which may be in the form of a menu display or voice prompting. The calling party then selects a call handling option which is forwarded to the SCP. The calling party may instruct the network to automatically set up a call with the called MS if the called MS is reactivated within a specified period of time.

Abstract: A system and method in a radio telecommunications network for reconnecting a disconnected emergency call between a mobile station having an emergency (emergency MS) and a public safety answering point (PSAP). The method reduces the probability that a second MS such as a cloned MS will respond to a reconnection attempt. If a second MS responds to a first reconnection attempt, procedures are implemented to locate and connect the emergency MS. The network includes a serving mobile switching center (MSC) serving the emergency MS that includes a re-paging mechanism and a reconnection timer. The PSAP includes an alarm generator that notifies the serving MSC when a second MS is connected to the PSAP rather than the emergency MS. Upon receiving an alarm from the PSAP, the serving MSC reattempts to page the emergency MS.

Abstract: A method of providing a list of digital control channel (DCCH) frequencies that are in use in a radio telecommunications network to a mobile station operating in the network. Each DCCH includes a superframe having an extended broadcast control channel (E-BCCH) time slot which is broadcast in an E-BCCH cycle. The method begins by dividing the list of DCCH frequencies into a plurality of DCCH subsets, and sequentially or randomly broadcasting the DCCH subsets to the mobile station in the E-BCCH time slot of the DCCH. The next DCCH subset is broadcast when the current E-BCCH cycle is completed. Alternatively, the next DCCH subset may be broadcast when a timer expires. In this case, a broadcast control channel (BCCH) change notification (BCN) indicator is changed whenever a new subset is broadcast.

Abstract: In a radio telecommunications network, a system and method of informing a called mobile station operating in a visited mobile switching center (V-MSC) that an incoming call is a collect call prior to delivering the incoming call to the mobile station. The system obtains in an originating mobile switching center (O-MSC), a collect call prefix from a calling party and determines from the collect call prefix that the incoming call is a collect call. A collect call indication (CCI) is generated and sent along with the calling number to the V-MSC in a Location Request (LocReq) Invoke message and a Routing Request (RoutReq) Invoke message, thereby notifying the V-MSC that there is an incoming call for the mobile station and the incoming call is a collect call. The V-MSC sets a collect call flag to ON, stores the calling number in a subscriber record in the V-MSC, and determines whether the mobile station is a digital mobile station.

Abstract: A coherent illuminator system and method wherein an incident energy beam is directed at an end of image conduit rotating around its axis. The incident energy beam may be generated by a laser, maser, or similar radiation source. A substantially cylindrically uniform radiation spot is obtained from the other end of the image conduit, which may be guided by waveguide means to an application element such as, for example, an emission microscope or a medical instrument.

Abstract: In a radio telecommunications network, a system and method of providing service differentiation for call forwarding based upon the type of call. The system provides network support that allows the forwarding of calls of different types to appropriate devices for each type of call, as identified by the call's service code. The system determines whether a call to a mobile station is a data call, and if it is a data call, provides the network support for forwarding the call to a different number than voice calls. A Service Type parameter is added to ANSI-41 signaling messages to inform various nodes in the network of the type of call. The network includes a home location register/service control point (HLR/SCP) with a database of call forwarding (transfer) numbers for its served mobile stations. The database records at least one transfer number for each type of service. Service logic in the HLR/SCP associates the type of call with the appropriate transfer number.
