    Abstract: A wireless communication architecture (100) includes a first wireless communication system (123) operating in the vicinity of a second wireless communication system (173). A System Locator (155) provides at least one operational parameter (330) of the first wireless communication system (123) to at least one dual-mode wireless subscriber communication unit (172) when operating in said second wireless communication system (173) via said second wireless communication system (173). The operational parameter (330) is based on a determined location of the at least one dual-mode wireless subscriber communication unit (172) for use by the at least one dual-mode wireless subscriber communication unit (172) in searching for and/or switching its operation to the first wireless communication system (123). The first system may be a TETRA or iDEN system and the second system may be a GSM system.

    Abstract: A mobile radio communication system has subscriber units 19-22 able to communicate by either full- or half-duplex within a home system 10. If a unit roams to a second system 11, linked to the first by a full duplex link 12, e.g. PSTN, a unit 19 resident in the home system cannot normally communicate by half-duplex. In the invention, a request from MS 19 to initiate a half duplex call to MS 21 is detected by the system in half duplex controller 16. The controller checks HLR 18 and identifies that the called MS 22 is not contactable over half-duplex. A failure message is returned to the calling mobile 19 advising re-try using full duplex Alternatively, the MS 19 can automatically switch to full-duplex on receipt of the message. In an alternative method, the failure message can be sent to the base station 14 handling the call and the format of the half-duplex communication from MS 19 is converted to full-duplex format compatible with link 12. On return, the reverse conversion takes place.
