1. A method of operating a wireless terminal, UE, connected to a network node associated to a serving cell of a radio access network, RAN, the method comprising:
receiving a request from the network node to report a cell global identifier, CGI, of a neighbor cell of the serving cell;
starting a timer responsive to receiving the request to report the CGI;
receiving system information from a neighbor cell;
determining from the system information if the neighbor cell does or does not broadcast the CGI of the neighbor cell;
transmitting a CGI report to the network node;
wherein if the neighbor cell does not broadcast the CGI, including into the CGI report a cell identifier field and an indication that the neighbor cell does not broadcast the CGI of the neighbor cell; and
transmitting the CGI report before expiration of the timer.
