摘要： There is provided a method and system for management of Machine Type Communication (MTC) events. The system and method enables the detection of a state of the MTC event, correlating the state of MTC event with a Virtual Network Function (VNF) state of a VNF configured to mitigate the MTC event and transitioning the VNF to the VNF state which correlates with the MTC state. In this manner, the VNF can be in a configured and active state in advance of the MTC event reaching a critical state, thereby enabling mitigation of the MTC event prior to reaching the critical state.

摘要： Aspects of the disclosure provide systems and methods for establishing one or more Distributed Gateways located close to a location of a UE to facilitate faster packet delivery to said UE during transitions. Such transitions can include the UE transitioning its state, for example from being idle to connected to the network, but also includes operations in which the serving AP(s) for the UE changes. The method includes establishing at least two virtual network function (VNF) components (VFNCs) of a distributed gateway (D-GW), each VNFC associated with an access point (AP). Each VNFC buffers packets directed to the wireless device. The method further includes selecting at least one AP for serving the wireless device, and forwarding the buffered packets from the VNFC associated with the selected APs to the selected APs for forwarding to the wireless device. Packets buffered at the VNFCs of non-selected APs are discarded.

摘要： A system and method for adaptively managing frame size in a wireless multihop network is disclosed. In one embodiment, a packet is transmitted from a source to a destination. A acknowledgement packet is received and a successful acknowledgement packet counter is incremented if the acknowledgement packet arrives prior to a time-out of a timer. A frame size is increased if the successful acknowledgement packet counter reaches a specified value. If the acknowledgement packet arrives after the time-out of the timer, the successful acknowledgement packet counter is reset and the frame size is decreased. These procedures can be repeated until the frame size is greater than or equal to a maximum frame size or less than or equal to a minimum frame size.

摘要： In a method of fractional frequency reuse in a communication network, a frequency band is divided into a plurality of sub-bands according to a Fractional Frequency Reuse (FFR) scheme to define a FFR allocation of the band for a plurality of bases stations, each of the base stations being associated with a respective region. At a first base station of the plurality of base stations, the first base station associated with a first region, communication with a mobile terminal in the first region is established on one of the plurality of sub-bands according to the FFR allocation.

摘要： One method of wireless communication involves acknowledging that an anchor base station received a handover indication signal. Another method involves: receiving, from base stations of an active set, offset signals identifying a respective differences in time between a reference time and respective times when the base station received a ranging signal from a mobile station; and transmitting, to the mobile station, a ranging control signal in response to the respective offset signals. Another method involves transmitting, to a mobile station in response to an active set signal, a system configuration information signal including system configuration information of a base station in an active set. Another method involves determining an uplink control channel power parameter in response to channel condition signals received from base stations in an active set. Another method involves transmitting a control signal to base stations in an active set on respective control channels. Apparatuses are also disclosed.
