This message is sent optionally on the SACCH by the network to mobile stations within the cell giving information on the extension of the BCCH allocation in the neighbour cells. See table 9.1.39.1.
A mobile station that supports either:
– only the primary GSM band P-GSM 900 (cf. 3GPP TS 45.005); or
– only the DCS 1800 band (cf. 3GPP TS 45.005);
