Abstract
A method of transmitting data packets to a cellular mobile unit, comprising: establishing a data transfer path for providing data from a data network gateway to a base station controller, for a first mobile station identity; and transmitting data received along the established path to at least one mobile station having at least one second identity different from the first identity.
Claims24
A multicast support unit, comprising:
- an input interface adapted to receive messages exchanged between mobile stations and a cellular packet support node;
- a filter adapted to identify in messages received by the input interface, not directed to the multicast support unit, messages which indicate an intent of a mobile unit to receive multicast data;
- and
- a controller adapted to instruct a mobile unit, indicated in a message identified by the filter, to receive a specific multicast channel.
1 more element
A method of establishing a terrestrial mobile connection, comprising:
- receiving a message indicating the intent of a mobile unit to receive multicast data, by an intercepting unit to which the message was not directed;
- and
- generating an instruction to the mobile unit to receive a multicast channel, responsive to receiving the message.
