Broadcast Information Update 2.1.5.
When changing broadcast information, the UE must be notified of the change using one of the following methods.
The method differs according to the UE in use.
A) Execute RRC Connection Reconfiguration
Notify the broadcast information update using the RRC Connection Reconfiguration message.
It updates information without ending a call. Use this procedure.
1. Execute RRCUPDATE RRCMSG to set Call Processing Parameter - radioResourceConfigCommon
Update to RRC Message.
NOTE 1: This setting is required once at the beginning of the measurement sequence.
B) Execute Paging
Notify the broadcast information update using Paging.
It updates information without ending a call. The MT8821C waits until the Paging information is reflected.
Use this procedure when procedure A cannot be used.
Waiting time at MT8821C
modificationPeriodCoeff [n] x defaultPagingCycle [rf = 10 ms]
NOTE 1: Setting both to the minimum value before position registration minimizes waiting time.
(Example) modificationPeriodCoeff (n2) × defaultPagingCycle (rf32) = 640 ms
1. Execute RRCUPDATE PAGING to set Call Processing Parameter - radioResourceConfigCommon
Update to Paging.
NOTE 2: This setting is required once at the beginning of the measurement sequence.
C) Turn UE power OFF and ON
Turn the UE power OFF and ON to update the broadcast information.
Use this procedure when procedures A and B cannot be used.
1. Disconnect Test Mode (2.1.4).
2. Turn off UE power.
3. Turn on UE power.
4. Execute CALLSTAT? to confirm the call processing status is 2 (= Idle (Regist)).
Repeat steps 4 when the checked status is not 2 (= Idle (Regist)).
5. Connect to Test Mode (2.1.4).
NOTE 1: This procedure is required to update the broadcast information.
