Section: 8.21 User Location Information (ULI)
Content: User Location Information (ULI) is a extendable IE that is coded as depicted in Figure 8.21-1. The CGI, SAI, RAI, TAI, ECGI and LAI identity types are defined in 3GPP TS 23.003[ Numbering, addressing and identification ]  [2]. Figure 8.21-1: User Location Information The ULI IE shall contain only one identity of the same type (e.g. more than one CGI cannot be included), but ULI IE may contain more than one identity of a different type (e.g. ECGI and TAI). The flags LAI, ECGI, TAI, RAI, SAI , CGI, Macro eNodeB ID, and Extended Macro eNodeB ID in octet 5 indicate if the corresponding type shall be present in a respective field or not. If one of these flags is set to "0", the corresponding field shall not be present at all. If more than one identity of different type is present, then they shall be sorted in the following order: CGI, SAI, RAI, TAI, ECGI, LAI, Macro eNodeB ID, Extended Macro eNodeB ID. Only one of the Macro eNodeB ID or Extended Macro eNodeB ID shall be present in the ULI IE. The following clauses specify the coding of the fields representing different identities. For each identity, if an Administration decides to include only two digits in the MNC, then "MNC digit 3" field of corresponding location shall be coded as "1111".
