1. A network apparatus configured to operate in a Long Term Evolution (LTE) network, the network apparatus comprising:

  • a processor;

    a wireless interface communicatively coupled with the processor; and

    a non-transitory computer readable storage device communicatively coupled with the processor and storing instructions that, when executed by the processor, cause the network apparatus to;

    determine whether a client device, which is in communication with the network apparatus via the wireless interface, is capable of hybrid operation on at least two distinct wireless networks, which operate using different radio access technologies (RATs), wherein;

    one of the at least two distinct wireless networks includes a Code Division Multiple Access 2000 (CDMA2000) wireless network from which the client device monitors pages by conducting tune-away events, the LTE network and the CDMA2000 wireless network operate independently, and the network apparatus is unaware of the client device'"'"'s connections to the CDMA2000 wireless network, anddetermination is based at least in part on a client identity of the client device, the client identity including at least one of;

    (a) user-related information and subscription-related information corresponding to the client device, wherein at least one of user-related information and the subscription-related information is available from a Home Subscriber Server (HSS) belonging to the LTE network, or(b) device-specific information comprising at least one of an International Mobile Equipment Identity (IMEI), a media access control (MAC address), or original equipment manufacturer (OEM) information specific to the client device; and

    when the client device is determined to be capable of hybrid operation;

    identify a CDMA2000 wireless network with which the client device can communicate;

    determine at least one scheduled tune-away event to be conducted by the client device to monitor pages from the CDMA2000 wireless network with which the client device can communicate, wherein the at least one scheduled tune-away event is determined based at least in part on an identifier of the client device and a schedule of tune-away events that is provided to the network apparatus by a mobile management entity (MME) of the LTE network; and

    during the at least one scheduled tune-away event, place an operational aspect of the client device, the operational aspect being associated with scheduling of network resources in the LTE network, in a suspended state in order to avoid loss of data from the LTE network, wherein the at least one scheduled tune-away event comprises the client device tuning away from the LTE network to the CDMA2000 wireless network.
