  • Dynamic allocation of radio resources in a packet switched communications-system
    Patent number: 8463707
    Abstract: Voice and/or image data packets are transferred by a packet handler between user stations in a GSM-type mobile communications system using a General Packet Radio Service (GPRS) data link. Control data for controlling a call is stored in a data store accessible by the packet handler. The control data identifies call participants and the identity of a participant who has currently seized the call. A mobile station capable of video conferencing is operable in a half-duplex video conferencing mode, in which intermittent transmission of video data is controlled by depression of a transmit button.

  • Mobile communications system having a cellular communications network comprising a public network portion and a private network portion using a common radio interface protocol
    Patent number: 6826414
    Abstract: A public mobile communications network is configured in accordance with an established protocol which includes a private network portion to which only a selected set of mobile stations have access. The selected set of mobile stations has a private network identity code which is different from a public network identity code. A base transceiver station of the private network portion broadcasts the private network identity code on its broadcast control channel. A mobile switching center prevents public subscriber mobile stations from registering via the private network portion, while the private subscriber mobile stations are allowed to register over the entire network.
