Question: What determines the inclusion of an Information Element within an Information Element group in RNSAP signalling over the Iur interface?
Option 1: The repetition factor of the group
Option 2: The name of the Information Element group
Option 3: The presence field of the Information Element itself
Option 4: The message type in which the group is embedded
Explanation: Within an Information Element group, each element's inclusion (whether it is mandatory, optional, or conditional) is specifically dictated by its own presence field. This field provides clarity on whether the element must always be present, may appear under certain conditions, or is not required when the group is included in a message. Thus, the presence field of the Information Element itself directly determines its inclusion within the group.
