Page response on existing radio signaling channel

A radio access network, comprising:

• a plurality of network links to establish call traffic communications with a plurality of core networks,
• a plurality of mobile station links to establish call traffic communications with a plurality of mobile stations,
• a page channel monitored by the plurality of mobile stations and in communication with the core networks to receive page requests for the establishment of call connections to the mobile stations,
• a multiplexer for combining call traffic communications from first and second core networks onto a single channel for communication of a plurality of calls to a single mobile station, said multiplexer being initiated by a page request on said page channel from said first core network and a page response on said single channel from said single mobile station.

A system for connecting a second call to a mobile radio engaged in an active first call, comprising:

• a first core network,
• a second core network,
• a generic radio access network in communication with said first core network via a first core network channel and with a second core network via a second core network channel and containing a page channel in communication with said first and second core networks,
• a plurality of mobile terminals in communication with said generic radio access network and monitoring said page channel, a first of said mobile terminals engaged in said active first call with said first core network via a mobile terminal call channel and the first core network channel,
• wherein said generic radio access network includes a multiplexer to receive via the mobile terminal call channel a page response signal from said first mobile terminal and to route the page response signal to the second core network via the second core network channel while continuing to route said active first call from said mobile terminal call channel to said first core network via the first core network channel.
