Patch Set 1:

Also, Wireshark is not smart enough to dissect IMSI in Packet Paging Request:

GSM RLC/MAC: PACKET_PAGING_REQUEST (34) (Downlink)
    01.. .... = Payload Type (DL): RLC/MAC block contains an RLC/MAC control block that does not include the optional octets of the RLC/MAC control header (1)
    ..00 .... = RRBP: Reserved Block: (N+13) mod 2715648 (0)
    .... 0... = S/P: RRBP field is not valid
    .... .000 = USF: 0
    PACKET_PAGING_REQUEST (34) (downlink)
