The send data without mandatory download procedure allows the receiving MCData client to accept download, defer download (i.e. no response) or refuse (e.g. by the user deleting the notification item) the data sent from the sending MCData client.
The procedure in Figure 220.127.116.11.2-1
describes the case where MCData user selected data is subjected to transmission control prior to transmitting data to the selected recipient user or affiliated members of the selected MCData group for downloading with recipient MCData user consent.
MCData user is configured with permission to transmit data.
Maximum amount of data or time that an MCData user can transmit in a single request is configured.
Time limit for the temporarily stored data waiting to be delivered to a receiving user is configured.
Optionally, MCData client may have an activated functional alias to be used.
The MCData server may have subscribed to the MCData functional alias controlling server within the MC system for functional alias activation/de-activation updates.
MCData user selects the data to transmit and the recipient MCData user or MCData group and does not select the mandatory download indication. The MCData user at MCData client 1 may include a functional alias used within the data transmission.
MCData client has checked for MCData user's permission to transmit data and the data size is within the maximum data size allowed. The MCData client calculates the total transmission request size and determines to select procedure described in subclause 18.104.22.168
, 22.214.171.124, 126.96.36.199 or 188.8.131.52 and without including the mandatory download indication.
Transmission control on the MCData server verifies if the MCData user is authorized to transmit, the data size in the received transmission request is within the maximum data size allowed and is within the maximum amount of time that a MCData user can transmit in a single request. MCData server verifies whether the provided functional alias, if present, can be used and has been activated for the MCData user.
MCData server may send one of the following control indications:
If the MCData user does not have permission to transmit data to another MCData user or MCData group then the "No permission to transmit data" control indication is sent.
If the selected transmission is for a MCData group and there are no affiliated group members, then the transmission control on MCData server sends the "No affiliated members found to the selected MCData group" control indication.
If the data size requested to be transmitted is more than the maximum amount of data that an MCData user can transmit in a single request, the transmission control on MCData server rejects the data transmission requests and sends the rejection control indication "Rejected due to exceeding data transmit size".
If the data transmission time exceeds the maximum amount of time that an MCData user can transmit in a single request (applies to DS only), the transmission control on MCData server rejects the data transmission request and sends the rejection control indication "Rejected due to exceeding data transmit time".
MCData server may queue the data transmit request for later transmission with a control indication "Request to transmit is queued".
Otherwise, continue with step 5.
MCData server transmits the data and, if available, the functional alias of the originating MCData client 1 to the selected MCData user or the affiliated members or all group members (in the case of lossless communication) of the selected MCData group according to the procedures selected in step 2 (where the recipient MCData client may receive the data automatically).
The MCData server may store the data in temporary storage (e.g. if the recipient is not available at the time of data delivery or network congestion or data deferred by the user) and may send MCData indication to notify the recipient of available data for retrieval:
If the timer expired for periodic announcement with the list of available recently invited data communications, the recipient MCData client waiting to receive the temporarily stored data receives MCData indication with the list of available temporarily stored data waiting to download in the Deferred data list .
If the temporarily stored data is expired, the data may be purged from the temporary store and the recipient MCData user may be informed in MCData indication with "Data expired and not available to download anymore" in the Deferred data list.
