26、nks. This is required since intersystem handoff is a tightly controlled activity of the cellular systems involved.

The message types are Unitdata (UDT) and Unitdata Service (UDTS). The SCCP shall return a UDTS message when a received UDT message cannot b

Whether to set the return message on error or discard message on error option in the Protocol Class parameter of the UDT message is at the discretion of the implementation.

43、has assigned the following Subsystem Numbers (SSN). Use of the following SSN values %se & recommended: - 5: Mobile Application Part (MAP) -6: Home Location Register (HLR) -7: Visitor Location Register (VLR) - 8: Mobile Switching Center (MSC) -9: Equipment Identification Register (EIR) (reserved) -1

The null SSN (i.e., value O) should be used when the subsystem is not known (e.g., before a global tit
