Section: 8.106 Node Number
Content: Node Number shall be coded as depicted in Figure 8.106-1. Figure 8.106-1: Node Number The Node number shall carry an ISDN number. If the Node Number carries the SGSN Number, then the SGSN number shall be coded according to the contents of ISDN-AddressString data type defined in 3GPP TS 29.002[ Mobile Application Part (MAP) specification ]  [41]. The SGSN Number shall be in international format and the "nature of address indicator" shall indicate "international number". The SGSN Number is defined in 3GPP TS 23.003[ Numbering, addressing and identification ]  [2]. The Length of Node Number shall not be zero. If the Node Number carries the MME number for MT SMS, then it shall be coded according to the contents of ISDN-AddressString data type defined in 3GPP TS 29.002[ Mobile Application Part (MAP) specification ]  [41]. The MME number for MT SMS shall be in international format and the "nature of address indicator" shall indicate "international number". The MME number for MT SMS is defined in 3GPP TS 23.003[ Numbering, addressing and identification ]  [2]. The Length of Node Number shall not be zero. If the Node Number carries the MSC Number, then the MSC number shall be coded according to the contents of ISDN-AddressString data type defined in 3GPP TS 29.002[ Mobile Application Part (MAP) specification ]  [41]. The MSC Number shall be in international format and the "nature of address indicator" shall indicate "international number". The MSC Number is defined in 3GPP TS 23.003[ Numbering, addressing and identification ]  [2]. The Length of Node Number shall not be zero.
