Section: 10.5.4.7 Called party BCD number
Content: The purpose of the called party BCD number information element is to identify the called party. The called party BCD number information element is coded as shown in figure 10.5.91/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.118/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The called party BCD number is a type 4 information element with a minimum length of 3 octets and a maximum length of 43 octets. For PCS 1900 the maximum length is 19 octets. Figure 10.5.91/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  Called party BCD number information element NOTE 1: The number digit(s) in octet 4 precedes the digit(s) in octet 5 etc. The number digit which would be entered first is located in octet 4, bits 1 to 4. NOTE 2: If the called party BCD number contains an odd number of digits, bits 5 to 8 of the last octet shall be filled with an end mark coded as "1111". Since the information element must contain the complete called party BCD number there is no need for an additional complete indication. Table 10.5.118/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] : Called party BCD number NOTE 1: For the definition of "number" see ITU-T Recommendation I.330 [48] and 3GPP TS 23.003[ Numbering, addressing and identification ]  [10]. NOTE 2: The type of number "unknown" is used when the user or the network has no knowledge of the type of number, e.g. international number, national number, etc. In this case the number digits field is organized according to the network dialling plan, e.g. prefix or escape digits might be present. NOTE 3: Prefix or escape digits shall not be included. NOTE 4: The type of number "network specific number" is used to indicate administration/service number specific to the serving network, e.g. used to access an operator. NOTE 5: The international format shall be accepted by the MSC when the call is destined to a destination in the same country as the MSC. Table 10.5.118/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] : Called party BCD number (continued) - When an MS is the recipient of number information from the network, any incompatibility between the number digits and the number plan identification shall be ignored and a STATUS message shall not be sent to the network. - In the case of numbering plan "unknown", the number digits field is organized according to the network dialling plan; e.g. prefix or escape digits might be present.
