7、the development of a TIA/EIA Standard. TIA/EIA Interim Standards should be reviewed on an annual basis by the formulating Committee and a decision made on whether to proceed to develop a TIA/EIA Standard on this subject. TIA/EIA Interim Standards must be cancelled by the Committee and removed from t

17、r TIA/EIA-664)Roamer Database Verification (RDV) enables a home system to verify that a roaming partnersVLR database is correctly loaded for the MSID number ranges that “belong” to the homeservice provider. At the request of the HLR, the VLR examines its roamer database to verifythat subscribers wit

An MC query to an MC regarding an MDN range.In any of these cases, the INVOKING NE requests the RESPONDING NE to examine

25、theindicated message routing database and to verify that the data stored for the indicated MSID orMDN range enables the routing of MAP messages to the INVOKING NE. The INVOKING NEcan request that contiguous blocks of MSID or MDN entries be examined by theRESPONDING NE. For backward compatibility, HL

If the INVOKING NE is authorized, the RESPONDING NE determines whichmessage routing database to examine based on the type of the INVOKING NE and the type ofrange (MSID or MDN) that has been provided for examination.The RESPONDING NE then examines that message routing database for the

29、 indicated range ofMSIDs or MDNs to determine whether the data needed to send a MAP message to theINVOKING NE is stored in the entries corresponding to that range. The RESPONDING NEresponds with a positive confirmation if every entry corresponding to that range is populated forthe INVOKING NE, or if
