Figure B.8 illustrates the delivery of a short message to a mobile subscriber.

The short message service center delivers the message to a GMSC or gateway function (1). The GMSC shall create an SMS gateway MT record.

The GMSC then interrogates the HLR of the subscriber to determine his current location (2). The HLR shall create an HLR interrogation record.

The message is subsequently transmitted to the MSC serving the mobile subscriber and finally to the mobile station of that subscriber (3). The MSC shall create an SMS MT record.

The records generated are subsequently transferred to the OS of the HPLMN (A).
