Claim 0:
1. A modem for a 5G New Radio (5G-NR) non-standalone network, the modem comprising a 5G-NR modem configured to receive radio frames from the 5G-NR network, the modem including a 5G-NR cell search module configured to:
determine first timing information, the first timing information comprising one or more first times, tk, indicative of the time of receipt of a respective one or more first radio frames, nk, from a first base station of the 5G-NR network, each radio frame having encoded therein a first system frame number (SFN), the one or more first times tk measured relative to a network time established by the 5G NR network and derived by the modem using, at least in part, information encoded in the radio frames; and
provide for sending of system frame timing difference (SFTD) information for the first base station to a network controller by sending said first timing information to a second modem for an Evolved Universal Terrestrial Access (E-UTRA) network, the second modem comprising an E-UTRA modem for determination and forwarding of the SFTD information by said second modem to the network controller using said first timing information and second timing information determined by the E-UTRA modem, the second timing information comprising one or more second times indicative of the time of receipt of a respective one or more second radio frames, m, from a second base station of the E-UTRA network, each radio frame having encoded therein a second system frame number (SFN).
