Optimized system access procedures

摘要

A base station subsystem (BSS) and a method are described herein for improving an Access Grant Channel (AGCH) capacity when mobile stations establish an uplink Temporary Block Flow (TBF) triggered by a small data transmission (SDT) or an instant message transmission (IMT). Plus, a mobile station (MS) and a method are described herein for improving the AGCH capacity when the mobile station establishes an uplink TBF triggered by a SDT or an IMT.

1. A base station subsystem (BSS) configured to interact with a plurality of mobile stations and perform a procedure to improve an Access Grant Channel (AGCH) capacity, the BSS comprising:
a processor; and a memory that stores processor-executable instructions where the processor interfaces with the memory and executes the processor-executable instructions to enable the following operations: broadcast a new system information (SI) to the plurality of mobile stations, where the new SI includes static radio parameters which are to be used by any one of the plurality of mobile stations when establishing an uplink Temporary Block Flow (TBF) to transmit a small data transmission (SDT) or an instant message transmission (IMT); receive, during an access time interval, multiple access requests from multiple mobile stations of the plurality of mobile stations, wherein the multiple mobile stations are each requesting to establish their respective uplink TBF to transmit the SDT or the IMT; in response to the received multiple access requests, send an immediate assignment message on the AGCH addressed to the multiple mobile stations, wherein the immediate assignment message includes multiple instances of at least a portion of dynamic radio parameters, wherein each one of the multiple mobile stations are to use their respective instance of the at least a portion of dynamic radio parameters along with the static radio parameters when establishing their respective uplink TBF to transmit the SDT or the IMT, and wherein the immediate assignment message has a constant format and a constant number of octets when addressing a variable number of the multiple mobile stations; and send multiple instances of a remaining portion of the dynamic radio parameters in a message on a Packet Associated Control Channel (PACCH) to the multiple mobile stations addressed by the immediate assignment message, wherein each one of the multiple mobile stations are to use their respective instance of the remaining portion of the dynamic radio parameters along with the static radio parameters and their respective portion of dynamic radio parameters included in the immediate assignment message when establishing their respective uplink TBF to transmit the SDT or the IMT.
