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 cellular communications network includes a plurality of cells (100) whos e 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 channe ls 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 antennna, output power backoff values associated with smart antenna a nd sector antenna support of the traffic channels in comparison to the control channel s, and power control attenuation applied to the traffic channels. The resulting adjusted downlink signal strength measurements may then be compared against each othe r (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
