25、A-41-D Chapter 1, page 1-30) A&ocedures for the implementation of the identified intersystem services have been defined with due regard to the following general considerations: I 8) The procedures defined here are based on the assumption that intersystem handoff relies upon dedicated intersystem tru

26、nks. This is required since intersystem handoff is a tightly controlled activity of the cellular systems involved. Intersystem handoff cannot be considered any differently than an inter- cell handoff. 1 I TiA/EiA-41-D Chapter 1 Modifications 3 Functional Overview 3. TIAIEIA-41-D Chapter 3 “Automatic

41、-8) For TIA/EIA-41 applications, the SCCP is defined in ANSI TI.112, with the following exceptions and limitations: SCCP Class O connectionless service is used. The message types are Unitdata (UDT) and Unitdata Service (UDTS). The SCCP shall return a UDTS message when a received UDT message cannot b

42、e delivered to the specified destination and has the return message on error option set. 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. The TIMEIA-41 Mobile Application Part

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

44、O: Authentication Center (AC) - 11: Short Message Service In accordance with ANSI TI.112 an SSN shall be included in all messages even if message routing is based on Global Title Translation (GTT). The null SSN (i.e., value O) should be used when the subsystem is not known (e.g., before a global tit
