System and method for inserting break-in signals in communication systems

A wireless repeater configured to facilitate channel-specific insertion of break-in signals, comprising:

• a first communication circuit for wirelessly communicating to and from one or more network infrastructure devices;
• a second communication circuit for wireless communicating to and from one or more mobile user terminals;
• a processing circuit coupled to the first communication circuit and second communication circuit, the processing circuit adapted to
• (a) receiving a plurality of downlink wireless signals from the one or more network infrastructure devices, each of the plurality of wireless signals comprising a plurality of different downlink communication channels, wherein the plurality of downlink wireless signals are broadcasted by the network infrastructure device to a plurality of mobile user terminals with which bidirectional communication links have been established with the network infrastructure device;
• (b) divide each of the plurality of downlink wireless signals into its plurality of downlink communication channels;
• (c) insert a break-in signal at the wireless repeater into a subset of all channels of the plurality of downlink wireless signals, where the break-in signal includes a marker tone, and insertion of the break-in signal interrupts, replaces, or mixes with an original signal in each of the subset of channels and the break-in signal includes a content message accessible by receiving mobile user terminals as the original signal, wherein the break-in signal is inserted into the wireless repeater by a party independent of an operator of the one or more network infrastructure devices and broadcasters of the plurality of downlink wireless signals;
• and
• (d) recombine the plurality of different downlink communication channels, including those with the inserted break-in signals, into the plurality of downlink wireless signals for retransmission.
