Abstract: A cell base station includes a first directive antenna array (104) (to form one beam (106) per cell sector) and a second directive antenna array (110) (to form a plurality of narrow (112) beams per cell sector). Location verification modules (132, 134) are further included for operation in connection with each of the first and second directive antenna arrays. To identify and characterize any difference in gain between the first and second directive antenna arrays, mobile station azimuth orientation with respect to the base station is determined and various signal strength and power related measurements and settings are collected from the mobile station and base station. The collected data is then mathematically processed (206, 228, 246) to determine a value indicative of the difference in gain between the first and second directive antenna arrays as a function of the azimuth orientation.

Abstract: A system and method of service provisioning in an integrated telecommunications network (402) having a packet-switched network portion (PSN) (102) and a circuit-switched network (CSN) portion (404) with a gateway (108) disposed therebetween. A service node (408) comprising a Service Control Point (SCP), a Service Data Point (SDP), or both is provided with an interface operable with the PSN portion (102). A first entity (e.g., served entity) is capable of accessing the service node (408) for the purpose of invoking a service. A return result (706, 726) from the service node (408) is provided, based on the decision of what action is to be taken with respect to the service request (704, 724), to the first entity which then determines how the action is to be effectuated. An indication is thereafter provided by the first entity to a second entity (e.g., re-routing entity) preferably using H.450.X messages. In response, the second entity (i.e., re-routing or switching entity) takes an appropriate service action based on the return result obtained from the service node (408). In a presently preferred exemplary embodiment, legacy service nodes built on the basis of WIN/IN service architecture are utilized for the provisioning of Value-Added Services (VAS) or Supplementary Services (SS) in VoIP networks operable with the H.450.X Recommendations.

Abstract: A D-AMPS+ cellular communications air interface (50) is presented wherein a packet data control channel (40, 60) and packet data traffic channel (42, 62) are supported in addition to the conventional digital control channel (20) and digital traffic channel (22, 64). In particular, the packet data control channel, packet data traffic channel and digital traffic channel support multiple modulation level operation (high versus low). Procedures are provided for intracell (76, 80, 82) and intercell (92, 94, 96, 98) modulation transition of mobile station communications carried by a traffic channel. In particular, these procedures facilitate intracell and intercell modulation transition to a traffic channel using the same level of modulation, as well as intracell and intercell (fall-forward and fall-backward) modulation transition to a traffic channel using a different level of modulation.

Abstract: A system for determining when a radio telecommunications network should swit ch between a first grade of service and a second grade of service based upon a highly accurate and reliable estimate of the b it error rate BER. The system estimates (65) the BER on an uplink and a downlink on a user channel, and determines (66) whether the BER on the uplink and the downlink on the user channel are below a first set of thresholds. The system then measures the residual SFET RBER and the frame erasure rate FER on the voice channel uplink, and determines (74) whether the downlink BER, the uplink RBER, and t he uplink FER are lower than a second set of thresholds. If lower, the system sends and receives a data message on a Fast Associated Control Channel (FACCH). The system obtains a highly accurate estimate (83) of the BER on a downlink on the FACCH channel, and reports (88 ) the downlink BER in a message on the FACCH channel uplink. The system then estimates the BER on the FACCH channel uplink. Finally, the system switches the radio telecommunications network from the first grade of service to the second grade of service in response to determining that the uplink and downlink BER on the FACCH channel are below a third set of thresholds.

Abstract: Utilizing a sequential local search optimization algorithm (30), a determination is made of the cell/transceiver retunes (32) needed to implement, given a current frequency plan, a better frequency plan for a certain cellular communications system. Each of the individual cell/transceiver retunes is evaluated (34) to determine if it meets certain save criteria, and if so, is saved as an intermediate frequency plan (74) in a sequence of saved intermediate frequency plans necessary to migrate from the current frequency plan to the determined near-optimal frequency plan. A sequential implementation (36) of these intermediate frequency plan revision s is then made to gradually reach, in a known and controlled manner, the bette r frequency plan.

Abstract: A cellular communications network includes a plurality of cells (100) whose base stations have both sector (104) and smart (110) antenna capabilities. While engaged in a call (200), mobile station (114) downlink signal strength measurements (202, 204) are made on its own serving traffic channel and the control channels of neighboring cells. These measurements are then adjusted (210) by one or more factors which take into account the operational and physical differences between sector antenna and smart antenna. For example, the signal strength measurements may be appropriately adjusted by measured differences in gain between the smart antenna and sector antenna, output pow er backoff values associated with smart antenna and sector antenna support of t he traffic channels in comparison to the control channels, and power control attenuation applied to the traffic channels. The resulting adjusted downlink signal strength measurements may then be compared against each other (as off - set by any imposed hysteresis value) to more precisely locate the mobile station and uniformly, predictably and accurately identify when it is appropriate to authorize a hand-off.

Abstract: A system for determining when a radio telecommunications network should switch between a first grade of service and a second grade of service based upon a highly accurate and reliable estimate of the bit error rate (BER). The system estimates the BER on an uplink and a downlink on a user channel, and determines whether the BER on the uplink and the downlink on the user channel are below a first set of thresholds. The system then measures the residual BER (RBER) and the frame erasure rate (FER) on the voice channel uplink, and determines whether the downlink BER, the uplink RBER, and the uplink FER are lower than a second set of thresholds. If lower, the system sends and receives a data message on a Fast Associated Control Channel (FACCH). The system obtains a highly accurate estimate of the BER on a downlink on the FACCH channel, and reports the downlink BER in a message on the FACCH channel uplink. The system then estimates the BER on the FACCH channel uplink. Finally, the system switches the radio telecommunications network from the first grade of service to the second grade of service in response to determining that the uplink and downlink BER on the FACCH channel are below a third set of thresholds.
