26.14.11 VGCS-VBS / User-to-Dispatcher Information
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
26.14.11.1 VGCS-VBS / User-to-Dispatcher Information / BCC MO call
26.14.11.1.1 Conformance requirement
The request of the calling subscriber to set up a voice group call may specify information to be sent as user‑to‑dispatcher information to the network; in this case the user-to-dispatcher information is included in the signalling for call setup from the mobile station to the network. It is the responsibility of the input function to ensure that the user-to-dispatcher information has a correct format (in particular, an allowed length).
The initial signalling from the originating service subscriber informs the network that a voice group call is required and details the group ID; it may specify user-to-dispatcher information.
The User-to-dispatcher information element is included in the SETUP message.

26.14.11.1.2 Test purpose
1. To verify that upon initiation of an outgoing broadcast call with User-to-Dispatcher information by the user, the MS includes a User-to-dispatcher information element in the SETUP message.
2. To verify correct establishment and clearing of the broadcast call.
26.14.11.1.3 Method of test
Initial Conditions
System Simulator:
1 cell with default parameters for ASCI testing.
Mobile Station:
The MS is in MM-state "idle, updated" with a TMSI allocated.
Specific PICS statements:
–
PIXIT Statements:
– Way to activate User-to-Dispatcher Information
– Way to configure VBS.
– Way to initiate VBS calls.
Foreseen Final State of the MS
"Idle, updated", with TMSI allocated.
Test Procedure
By means of appropriate MMI function, the user enters a string, which shall be included in the User-to-Dispatcher Information.
Then MS is made to initiate a broadcast call. In the SETUP message, the User-to-dispatcher information element shall be present and shall include the requested string. Then, SS releases immediately the call with a TERMINATION message.
Then MS is made to initiate a second broadcast call with User-to-Dispatcher Information including a long string. In the SETUP message, the User-to-dispatcher information element shall be present with the requested string. Then it is checked that the call can be successfully established and cleared.
Maximum Duration of Test
