1. A base station subsystem (BSS) (102) configured to interact with a plurality of mobile stations (1041, 1042, 1043, 1044 . . . 104n) and perform a procedure to improve an Access Grant Channel (AGCH) (106) capacity, the BSS comprising:

  • a processor (110); and

    a memory (112) that stores processor-executable instructions where the processor interfaces with the memory and executes the processor-executable instructions to enable the following operations;

    broadcast (202b) a new system information (SI) (120) to the plurality of mobile stations, where the new SI includes an indicator (302) which indicates to the plurality of mobile stations that the BSS is configured to perform the procedure to improve the AGCH capacity;

    receive (204b) at least one access request (124) from at least one of the plurality of mobile stations (1041 and 1043), where the at least one mobile station is requesting to establish an uplink Temporary Block Flow (TBF) (128) to transmit a small data transmission (SDT) (130a) or an instant message transmission (IMT) (130b); and

    in response to the received at least one access request, send (206b) an immediate assignment message (132) on the AGCH for the at least one mobile station, where the immediate assignment message includes static radio parameters (134) and at least a portion of dynamic radio parameters (136) which are to be used along with the static radio parameters by the at least one mobile station when establishing the uplink TBF to transmit the SDT or IMT.
