  • Radio link short hold mode for mobile circuit data applications
    Patent number: 5903851
    Abstract: A method and apparatus for providing a call circuit connection between a mobile station and a remote application host is disclosed. Once a call circuit connection is initially established between a mobile station and remote application host to enable data to transfer therebetween, the call circuit connection is monitored for detection of an idle condition. Upon detection of the idle condition, identifying information for the call circuit connection is stored, and a first portion of the call circuit connection is disconnected while maintaining a second portion of the connection. Upon a request for reconnection of the call circuit connection, the first portion of the call circuit connection is reestablished with the second portion to enable continued data transfer.
