    摘要： Efficient delivery of subscription content over a wireless network is described herein. In one implementation a device may receive load information regarding network traffic load at radio interfaces for a cellular network. The device may maintain subscription information relating to subscribers that have subscribed to receive content items and to availability of the content items. The device may determine whether a quantity of mobile devices, that are attached to the base station and are associated with subscribers that have subscribed to the first content item, is above a threshold. Finally, the device may transmit, when it is determined that the quantity of mobile devices is above the threshold, the first content item to the quantity of mobile devices as a multicast transmission over a radio interface associated with the base station.

    摘要： A device, provided at a network edge, receives a radio frequency signal from a user equipment, and converts the radio frequency signal into an electrical signal. The device also receives, from a network controller, at least one of control information, schedule information, or congestion management information. The device performs baseband signal processing on the electrical signal, based on at least one of the control information, the schedule information, or the congestion management information, to create a modified signal. The device provides the modified signal to the network controller.

    摘要： One or more devices determine uplink signal strength for a machine-to-machine (M2M) device using a wireless access network. The one or more devices identify a default uplink transmission mode that requires the M2M device to employ transmission time interval (TTI) bundling, when the uplink signal strength is below a particular threshold, and identify a default uplink transmission mode that requires the M2M device to not employ TTI bundling, when the uplink signal strength is not below the particular threshold. The one or more devices store, in a memory, the default transmission mode for the M2M device. The one or more devices retrieve, from the memory and during a wake-up time window associated with the M2M device, the default transmission mode for the M2M device and construct, for the M2M device, an uplink scheduling grant based on the stored default transmission mode.

    摘要： A device classifies access or control channel signals into a first class or a second class, initializes a dormancy timer associated with the device, and sets the dormancy timer to a default value. The device also sets a signal target utilization threshold, receives actual signals via the access or control channel, and identifies, when a number of the actual signals exceeds the signal target utilization threshold, a particular signal, from the actual signals, as belonging to the first class or the second class. The device further increases the default value of the dormancy timer when the particular signal belongs to the first class, and decreases the default value of the dormancy timer when the particular signal belongs to the second class.
