7.4 Short data service p. 53
7.4.1 General p. 53
There are several procedures how an SDS message can be transported from the sender to the recipient. All of the following factors are used by MCData client for selecting appropriate SDS procedures:
- Whether the data to transfer is within or outside the SDS data size limit to transport over signalling control plane;
- Whether the MCData user has only one SDS transaction or multiple SDS transactions;
- Whether MCData user, optionally using its associated and activated functional alias, is targeting SDS transaction to another MCData user or MCData group;
- Whether MCData UE is on-network or off-network; and
- Security reasons.
