Abstract: Circuitry and method for effectuating low power read operations in a memory circuit, e.g., a memory instance having a banked architecture. When a memory read cycle is initiated with respect to a particular memory cell in a selected bank based on a plurality of address signals, a specific wordline associated with the memory cell is driven high. Upon waiting until the bitline coupled thereto reach a predetermined sense level, the wordline is shut off based on a reference memory cell structure, which wordline thereby stops driving the bitline. Subsequently, after waiting for a select time, the sense amplifier senses the data stored in the particular memory cell based a charge distribution between its internal node(s) and the bitline after the selected wordline is deactivated.

Abstract: A method and system for determining whether at least one telephone subscriber participating in a communication session is marked for monitoring by a Law Enforcement Agency (LEA) and, if so, for automatically marking for monitoring all remaining participants in the communication session. In a presently preferred exemplary embodiment, the subscribers are marked for monitoring their communications for a selected period of time by a starting the timer each time a new subscriber is marked.

If so, the corresponding subscriber is marked for monitoring and the subscriber's subsequent communications are monitored.

Abstract: An apparatus (10) and method for selectively monitoring radar signals impinging on a vehicle is disclosed. The apparatus (10) comprises a speed determination circuit (20) that determines vehicle speed and provides a speed signal representative thereof to a comparator (22) that compares the speed signal to a preselected speed and provides an on signal when the vehicle speed exceeds the preselected speed and an off signal when the vehicle speed is at or below the preselected speed. When the comparator (22) provides the on signal, a radar detecting circuit (14) is powered to detect incoming radar signals and provide a radar detected signal to an alarm (18) that provides an alert in response to the radar detected signal. When the comparator (22) provides the off signal, the radar detecting circuit (14) is not powered and does not detect incoming radar signals.

Abstract: A system and method for effectuating selective triggerless local number portability (TLNP) processing in a telecommunications network having a cellular network portion and a wireline network portion. When an IAM message is received at a signaling node from an MSC on a TLNP-enabled link set, a determination is made at an STP associated therewith whether the NPA-NXX of the received dialed number is marked as portable. If not, the TLNP processing is discontinued and the message as originally received is forwarded to the wireline network portion for further processing. Otherwise, another determination is made if the dialed number is a ported number. If it is determined that the dialed number is not a ported number, the IAM message is marked as dipped and forwarded to the wireline network portion based on the Destination Point Code (DPC) associated with the message.

Abstract: Circuitry and associated method for resetting a memory storage cell without a dedicated write cycle therefor. Preferably, the storage cell is provided as part of an age_array employed for monitoring the usage of a Content Addressable Memory (CAM). When a match between search data and contents of a particular location of the CAM is found, a Match signal is generated to set a memory storage cell (referred to as an age_cell) corresponding to the particular CAM location. When the age_array is read, the wordline associated with the age_cell is driven high. Upon developing a voltage separation between the data and data bar nodes of the age_cell, a sense amp senses the data value on the corresponding bit and bit bar lines coupled thereto. A suitable data out signal is generated for outputting the sensed data. Also, a reset control signal is generated to indicate that the read operation is substantially complete with respect to that age_cell.

Abstract: A circuit for selectively erasing a semiconductor memory instance on a per I/O basis. The circuit is provided as a tilable architectural element in a memory compiler for the semiconductor memory instance. A plurality of pass gates are disposed between global wordlines provided by the row decoder of the memory array and local wordlines that select memory bit cells in a particular I/O. One or more memory clear signals are used to decouple the local wordlines from the global wordlines and to connect them to a high voltage node, VDD. The I/O is cleared by placing a predetermined logic state (typically 0) on the bitline nodes of the I/O and selectively coupling the local wordlines to the VDD node.

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: A method of writing additional foreign data either to a blank magnetic card and/or to an existing magnetic striped card is used to consolidate information from possibly multiple credit type cards onto a single card. The additional data that may be from multiple cards or that may be generated or gathered from other sources can then be written to a single card for example to consolidate the information.

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.

Abstract: A row and column accessible memory having a plurality of memory cells organized as an array of N rows and N columns with a built-in multiplex. A control logic block and decoder block are operable to effectuate either a row access operation for accessing a selected row or a column access operation for accessing a selected column based on a plurality of address signals supplied to the memory. Each memory cell is provided with a first pair of read and write ports for effectuating the row access operations (controlled through row read wordline select and row write wordline select signals, respectively) and a second pair of read and write ports for effectuating the column access operations (controlled through column read wordline select and column write wordline select signals, respectively). A single I/O block is utilized for sensing and data I/O operations, which requires less silicon area and avoids extra routing required in the conventional solutions.
