A point to multipoint channel extension protocol and system are disclosed. More particularly, the system includes an extension protocol for extending a point to point radio link between a primary station and a secondary station to a point to multipoint radio link in which the primary station broadcasts to the secondary stations. This is done by first informing the handset to which a point to point radio link has been set up that an extension is to be done so that the handset can switch off its transmitter, and then transmitting extension messages to all handsets. Furthermore, a transfer and skipping protocols are proposed with a reliable connection establishment by using a double checking protocol for seizing a pair of free channels.
A telecommunications system comprising at least one primary radio station and a plurality of secondary radio stations, wherein at least one secondary radio station is matched to a primary radio station, each station has a transmitter and a receiver, characterised in that the primary station is arranged for setting up a point to point full duplex communication link to a matched secondary station or vice versa, and that the primary station is arranged for issuing a extension request to the matched secondary station and to further matched secondary stations after the setting up of the point to point communication link, and the secondary station to which the communication link has been set up switches off its transmitter, and the matched secondary station and the further matched secondary stations have their receivers ready for receiving a broadcast message from the primary station.
A channel extension protocol for use in a telecommunications system comprising at least one primary radio station and a plurality of secondary radio stations, in which system a secondary radio station is matched to a primary radio station, whereby the stations have a transmitter and a receiver, characterised in that the primary station sets up a point to point full duplex communication link to a matched secondary station or vice versa, and that the primary station issues a extension request to the matched secondary station and to further matched secondary stations after the setting up of the point to point communication link, that the secondary station to which the communication link has been set up switches off its transmitter, and that the matched secondary station and the further matched secondary stations have their receivers ready for receiving a broadcast message from the primary station.
A primary radio station for use in a telecommunications system. the telecommunications system including at least one primary radio station and a plurality of secondary radio stations. wherein each secondary radio station includes a transmitter and receiver, wherein a secondary radio station is matched to a primary radio station, the primary radio station comprising:
A telecommunications system comprising at least one primary radio station and a plurality of secondary radio stations, in which system at least one secondary radio station is matched to a primary radio station, whereby the stations have a transmitter and a receiver, characterised in that the primary station is arranged for setting up a point to point full duplex communication link to a matched secondary station or vice versa, that the secondary station to which the full duplex communication has been set up is arranged for transmitting a transfer message to the primary station for transferring the link to another matched secondary station, that the primary station transmits a release request to the secondary station to which the link has been set up, and that the primary station issues a link establishment request for establishing a full duplex communication link with the other matched secondary station.
A telecommunications system comprising at least one primary radio station and a plurality of secondary radio stations, in which system at least one secondary radio station is matched to a primary radio station, whereby the stations have a transmitter and a receiver, characterised in that the primary station is arranged for setting up a point to point full duplex communication link to a matched secondary station or vice versa, that the secondary station to which the full duplex communication has been set up is arranged for transmitting a channel skip message to the primary station for skipping the link to another channel, that the primary station transmits a release request to the secondary station to which the link has been set up in response to which the secondary station enters a channel scanning mode, that the primary station issues a link establishment skip request for establishing another full duplex communication link with the secondary station, and that the primary station transmits a skip off message to the secondary station after having set up the other communication link.
