Cell update for optimized system access procedures between base station subsystems and mobile stations

摘要

One embodiment is directed to a method implemented by a mobile station for establishing a downlink temporary block flow (TBF) from a base station subsystem (BSS). Cell re-selection is performed while a READY timer of the mobile station has not expired. A cell update message that includes a radio link control (RLC) data block containing a remaining ready timer value indicating a remaining time of the READY timer, which has not expired, is sent to the BSS for use in determining when a mobile station supports the assignment of a TOI, sending an assigned TOI to that mobile station and establishing subsequent downlink TBFs using the assigned TOI instead of a legacy mobile station identity. Another related embodiment is directed to a method implemented by a BSS for establishing downlink TBFs to a plurality of mobile stations.

1. A method implemented by a mobile station for establishing a downlink temporary block flow (TBF) from a base station subsystem (BSS), the method comprising the steps of:
performing cell re-selection while a READY timer of the mobile station has not expired; following cell re-selection, receiving system information (SI) that is broadcast by the BSS; determining from the SI whether the BSS is capable of assigning a temporary optimized system access procedure identity (TOI) to the mobile station for use in establishing downlink TBFs; and responsive to determining that the BSS is capable of assigning a TOI to the mobile station, sending a cell update message comprising a radio link control (RLC) data block containing a remaining ready timer value indicating a remaining time of the READY timer, which has not expired, to the BSS for use in establishing subsequent downlink TBFs.
