    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： 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： A method of generating a network slice is provided. The method comprises a network slice orchestrator (NWSO) receiving from a network slice manager (NWSM) a request for a new network slice, the NWSO adding a new service to the new network slice, the NWSO determining a network slice descriptor (NWSD) for the new network slice, the NWSO transmitting to a resource orchestrator (RO) a request for an instantiation of the network slice using enhanced network function virtualization management and orchestration (E-MANO). A method of modifying a network slice is also provided. The method comprises a NWSO receiving from a NWSM a request to add a new service to a network slice, the NWSO adding a new service to the network slice, the NWSO determining a NWSD for the network slice with the added service, and the NWSO transmitting to a RO a request for an instantiation of the added service on the network slice using E-MANO. A method of terminating a network slice is also provided. The method comprises a NWSO receiving from a NWSM a request to terminate a network slice, the NWSO determining the subnetworks to terminate, and the NWSO transmitting to a RO a request for a termination of the slice specific network functions (NFs).

    摘要： A method and system for fractional frequency reuse in a communication network. A plurality of fractional frequency reuse modes for wireless communication are defined in which each of the modes are associated with a corresponding group of wireless communication tones assigned to one of a plurality of power levels. Communication with at least one mobile terminal in a first region is established using a fractional frequency reuse mode from the plurality of fractional frequency reuse modes. A coverage problem with communication with at least one of the mobile terminal in the first sector is detected. A base station associated with a second region is notified to change communication within the second region to a different fractional frequency reuse mode from the plurality of fractional frequency reuse modes.
