A method operates, in at least one network control mode of operation (preferably NC), for determining in a MS if a cell to which the MS is currently assigned has a first type of broadcast control channel (the PBCCH) and, if the cell does have the first type of broadcast control channel, for sending a PACKET MEASUREMENT REPORT message to the network for reporting on neighbour cells identified in a list received from the PBCCH. If the cell does not have the PBCCH, the method instead sends a PACKET MEASUREMENT REPORT message to the network for reporting on neighbour cells identified in a list received from a second type of broadcast control channel (BCCH). The type of list used by the MS is one of implicitly specified by the PACKET MEASUREMENT REPORT message, or is explicitly specified by the PACKET MEASUREMENT REPORT message.

Method and apparatus providing performance improvement for GPRS neighbour cell measurement reporting when packet broadcast control channel is not available

A General Packet Radio Service GPRS, Global System for Mobile Communications GSM/Universal Mobile Telecommunications System UMTS mobile station ( ) in accordance with these teachings includes a radio frequency transceiver ( ) for communication with a wireless network ( ) and a controller ( ) responsive to a receipt of information from the wireless network for reporting 3G cells when operating in a GSM dedicated mode on a cell that has a Packet Broadcast Control Channel PBCCH. The controller is enabled to report the 3G cells before receipt of the 3G Neighbor Cell list from the MEASUREMENT INFORMATION message. The information includes a 3G Neighbor Cell list received in a PACKET SYSTEM INFORMATION Type quater message on the PBCCH, and a 3G_BA_IND information element received in the PACKET SYSTEM INFORMATION Type quater message. The controller reports the 3G cells using a MEASUREMENT REPORT message that reflects a value of the received 3G_BA_IND information element. In another embodiment a PSI _CHANGE_MARK information element is received in the PACKET SYSTEM INFORMATION Type quater message, and the LSB of the PSI _CHANGE_MARK information element is used by the mobile station as a 3G_BA_IND information element.
