  • Patent number: 5926469
    Abstract: A disconnect time in accordance with the Global System for Mobile (GSM) Phase 1 standard is reduced within a particular base station controller (BSC) serving a particular mobile station. In response to a Layer 2 Disconnect message from a first mobile station and after the expiration of the reduced disconnect timer, the serving BTS releases the indicated logical channel from the first mobile station and enables the connected base station control (BSC) to more efficiently allocate the released logical channel (SDCCH or TCH) to a second mobile station. Thereafter, additional Layer 2 Disconnect messages transmitted by the first mobile station are ignored and no acknowledging Disconnect Mode (DM) message is transmitted over the indicated logical channel. Thus, collision over the same logical channel between the first and second mobile stations is avoided and the second mobile station is able to communicate over the allocated logical channel.
