Bei den ersten zwei Ziffern der U-CID handelt es sich um die ID des "Controlling RNC" (CRNC-ID).
Nachzulesen in 3GPP TS 25.401:
...
6.1.5 Cell Identifier
The Cell identifer (C-Id) is used to uniquely identify a cell within an RNS. The Cell-Id together with the identifier of the controlling RNC (CRNC-Id) constitutes the UTRAN Cell Identity (UC-Id) and is used to identify the cell uniquely within UTRAN. UC-Id or C-Id is used to identify a cell in UTRAN Iub and Iur interfaces.
UC-Id = RNC-Id + C-Id.
The C-Id is defined by the operator, and set in the RNC via O&M. The C-Id is set in a Node B by its C-RNC.

Interessant wäre nun, ob bei den einzelnen Betreiber eine Location Area mehrere RNC's beinhaltet, oder ob die Regel RNC=LAC gilt?
Hat hierzu irgendwer eine Info?
