Abstract: A mid-call feature of a voice call server, such as an IP PBX or IP Centrex system, is accessed during a call. During the call with a mobile terminal via a mobile telephone network, a voice call signal associated with a mid-call feature from the mobile terminal is passed over a mobile telephone network to a first communication system. The voice call signal is converted to a data call signal at the first communication system, and the data call signal is transmitted to a second communication system over the data network. The method can also include providing the mid-call feature in response to receipt of the data signal at the second communication system.

Abstract: A telecommunication approach provides telephone service to subscribers on terminals registered on a mobile network that are consistent with the services provided to those subscribers at terminals on a fixed communication network. For instance, the subscriber on the terminals on the mobile network may have access to mid-call features and private dialing plans that are supported using elements on the fixed network, and calls placed to the subscribers at addresses (e.g., wireline numbers or SIP addresses) on the fixed network may be delivered to their terminals on the mobile network.

Abstract: A method and apparatus for a handover of a communication signal (370) associated with a mobile communication unit (116) between a Generic C-based wireless communication system (302) and a MSC-based wireless communication system (304), is disclosed. The handover method includes establishing a plurality of trunks (401) between a landline switch (316) and a MSC (317). The method also includes configuring a landline number routing table (403) and a landline trunk group table (404) in the landline switch (316), a mobile trunk group table (406) in the MSC (317), and establishing a message translation table (405) in the computing platform (312), such that one of the plurality of trunks and an associated signaling path to the computing platform (312) are always selected when the handover is required.

Abstract: Detection of a fraudulent remote unit (113) in a communication system (100) occurs by external fraud detection equipment (103) located external to, and in proximity to a base site (101). External fraud detection equipment (103) communicates with base site (101) via an uplink communication signal (105) and utilizes fraud detection methods not utilized by internal fraud detection equipment (111) to identify the remote unit (113) as being fraudulent. Once the remote unit (113) is identified by the external fraud detection equipment (103) as being fraudulent, the external fraud detection equipment (103) places an origination order to the base site (101) and supplies identification information on the fraudulent remote unit (113). Infrastructure equipment (109) utilizes information supplied to it by the external fraud detection equipment (103) and disconnects the fraudulent remote unit (113).
