Abstract:
A coax line terminal (CLT) transmits allocations of upstream bandwidth to a plurality of coax network units (CNUs). In response to the allocations, the CLT receives frames with data in a plurality of physical resource blocks that each correspond to a distinct set of subcarriers. The plurality of physical resource blocks includes a first group of physical resource blocks that all have a first constant allowed capacity. Sizes and modulation orders of respective physical resource blocks in the first group vary as defined by a first modulation profile. The data in the first group are received from one or more CNUs that are assigned the first modulation profile.
Abstract:
A coax line terminal includes a first media access controller (MAC) corresponding to a first group of coax network units and a second MAC corresponding to a second group of coax network units. The coax line terminal also includes a first physical media entity (PME), coupled to the first MAC, to generate signals for transmission in a first frequency band, and a second PME, coupled to the first and second MACs, to generate signals for transmission in a second frequency band. The coax line terminal further includes a PME multiplexer to control access of the first and second MACs to the second PME.
Abstract:
Methods and apparatuses are provided that facilitate downloading and/or applying policies for a current configuration of network interfaces. Where a network interface of a device is deactivated or otherwise losses connection, the device can ensure policies for communicating without the network interface are enforced. Where such policies are not available, the policies can be downloaded to ensure the device stores policies for the network interface configuration.
Abstract:
A communication entity (such as a User Equipment (UE), an Access Gateway (AGW), a Packet Data Network Gateway (PGW), a Policy Charging Rule Function (PCRF), and so forth) notifies another communication entity that the UE intends to use a single Internet Protocol (IP) address for connections to multiple AGWs. The communication entity also sends information that is related to at least one of the UE's IP flows to another communication entity.
Abstract:
Methods and systems are disclosed for centralized self-organizing network (cSON)-aided small cell load balancing based on backhaul information. In an aspect, a cSON server receives periodic or event triggered backhaul capacity reports from each of the plurality of small cell base stations, a backhaul capacity report indicating an uplink and/or downlink capacity state of a backhaul connection over which a small cell base station of the plurality of small cell base stations is connected to a core network, determines load balancing assistance data for at least one of the plurality of small cell base stations based on the backhaul capacity reports received from each of the plurality of small cell base stations, and provides the load balancing assistance data to the at least one of the plurality of small cell base stations.
Abstract:
An apparatus and method for allocating a data flow based on selection criteria including receiving at least one policy including at least one indication for selecting an access from two or more of available accesses (710); determining a selection criterion based on the data flow (720); and selecting the access based on the determined selection criterion and the at least one indication (730). In one example, the selection criterion is one of the following: a bandwidth requirement for the data flow, an application generating the data flow, a protocol used to carry the data flow, a file size, an application name/ID, a role ID, or a throughput of the data flow. In one example, the policy is a management object (MO) received from an Access Network Discovery and Selection Function (ANDSF) module and the selected access is for a wireless local area network (WLAN), a LTE network or for a 3GPP service.
Abstract:
Methods and apparatuses are provided that facilitate detaching one of a plurality of network connections to ensure state information is retained at one or more network nodes. For a device initiated detach, the device can transmit a handover message related to performing a handover of one network connection to another active network connection, as opposed to explicitly detaching the network connection. This can cause at least some state information, such as a gateway identifier, to be retained in one or more network nodes. For a network initiated detach, a gateway can provision state information to a state information server following receiving a routing tunnel termination message to ensure state information deleted as a part of the detach is re-provisioned to the state information server.
Abstract:
Methods and apparatus for adjusting transmission power in wireless networks are provided. One aspect of the disclosure provides a method of wireless communication over a wireless communication medium. The method includes determining a level of interference for a data transmission from a transmitting device to an intended receiving device. The method further includes setting a transmission power level for transmitting a message based on the interference level, the message comprising one of a request-to-send (RTS) packet and a clear-to-send (CTS) packet. The method further includes transmitting the message at the set transmission power level.
Abstract:
In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.
Abstract:
A fiber-coax unit (FCU) is coupled to an optical line terminal (OLT) and a plurality of coax network units (CNUs). The FCU receives a multicast frame from the OLT. The multicast frame includes a first multicast logical link identifier (LLID) dedicated for multicast traffic directed to CNUs. The FCU replaces the first multicast LLID in the multicast frame with a second multicast LLID corresponding to one or more multicast groups that include at least one CNU of the plurality of CNUs. The FCU transmits the multicast frame to the plurality of CNUs.
