  • Publication number: 20180270636
    Abstract: 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.

  • Patent number: 10080105
    Abstract: The present invention provides a system and method for managing a mobile object using a plurality of machine type communication devices (MTCDs) communicatively connected to a communication network. A mobile object can be considered a virtual MTCD which can be managed and/or tracked by an array of MTCDs which are communicatively connected with the communication network. The MTCDs detect the mobile object and obtain or determine one or more parameters indicative of movement of the object. By tracking the movement of the object, the system can substantially ensure that there are connected MTCDs in the area to which the object is moving, thereby enabling the management and/or tracking of the mobile object can be provided by actively modifying the configuration of the communication network, for example using network function virtualization.

  • Patent number: 10075907
    Abstract: Methods and apparatus for management of network slices in a communication network such as a 5th generation wireless communication network are provided. Management planes may be provided which are separate from the plurality of network slices. A connection manager residing in a management plane receives an indication that a mobile device is to be associated with the communication network. The connection manager may reside at an access node or in the core network. A network slice is determined, and the connection manager transmits instructions, to one or more network nodes, to associate the mobile device with the network slice. The instructions may be provided to a local connection manager. The slice may be requested explicitly by the mobile device, or determined based on device and/or network requirements.

    Abstract: Implementations of a registration procedure are described. The registration procedure includes a Access and Mobility Function (AMF) selection procedure and a Session Management Function (SMF) selection procedure. The AMF receives a Non-Access Stratum (NAS) registration request pertaining a User Equipment (UE). At least partially in response to the registration request: the AMF registers the UE on the network; and establishes a Protocol Data Unit (PDU) session for the UE. The AMF transmits a registration response to the UE. An access node of the network receives a Radio Resource Control (RRC) registration request from a User Equipment (UE). At least partially in response to the registration request: The access node selects an AMF, and forwards a corresponding Non-Access Stratum (NAS) registration request to the selected AMF. The NAS registration request includes PDU session request information pertaining to the UE.

  • Publication number: 20180213453
    Abstract: 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.

  • Patent number: 10028168
    Abstract: A method and system for supporting operation of a scheduler by providing indications of communication device transmit buffer status is provided. The indication of buffer status can be generated by a third-party device which is external to both the communication device and the scheduler. In some embodiments matched local and remote models of the buffer are maintained at the communication device and third-party device (or scheduler), respectively. The communication device monitors locally for drift of the model from the actual buffer status. When a level of mismatch in the model is detected, both the local and remote models are updated to mitigate the mismatch.

  • Patent number: 10009149
    Abstract: Methods described herein are for wireless communication systems. One aspect of the invention is directed to a method for a HARQ process, in which the HARQ process includes a first transmission of an encoder packet and at least one retransmission. The method involves allocating a transmission resource for each respective transmission. The method involves transmitting control information from a base station to a mobile station for each respective transmission. The control information includes information to uniquely identify the HARQ process and an identification of one of a time resource, a frequency resource and a time and frequency resource that is allocated for the transmission. In some embodiments of the invention, specific control information is signalled from a base station to a mobile station to enable RAS-HARQ operation. In some embodiments of the invention, retransmission signaling in included as part of regular unicast signaling used for both first transmission and retransmissions.

  • Patent number: 9974060
    Abstract: Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted the resource request based on the resource request channel characteristics of the resource request channel upon which the resource request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.

  • Patent number: 9912505
    Abstract: The description herein relates to pilot designs for an Orthogonal Frequency Division Multiplexing (OFDM) based communication system. In at least one embodiment, the communication system is one operating according to the IEEE 802.16m, or WiMax, standard. In general, an OFDM transmitter operates to insert pilot symbols into a resource of a transmit frame according to a predetermined staggered pilot symbol pattern defining pilot symbol locations within the resource of the transmit frame. The predetermined pilot symbol pattern is defined such that pilot symbols are located at or near time boundaries of the resource, at or near frequency boundaries of the resource, or both. By doing so, when generating a channel estimate for the communication channel between the OFDM transmitter and an OFDM receiver based on the pilot symbols, extrapolations needed to estimate the channel near the boundaries of the resource are optimized, thereby improving overall channel estimation accuracy.
