摘要:
There is disclosed a system for transmitting data to users. The system includes nodes interconnected by at least one data network. The nodes are organized hierarchically to comprise a root node and at least two child nodes. The data transmission characteristics of communication with each of the child nodes are different. The root node is configured to: receive data transmission preferences of a particular user; receive data to be transmitted to the particular user; and transmit a selected subset of the data to at least one of the child nodes. The subset selected based on at least the received data transmission preferences and the data transmission characteristics, to permit the particular user to obtain data from the child nodes according to the data transmission preferences. The at least one of the child nodes being configured to: receive data from the root node; and transmit at least part of the received data to the user.

A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

Embodiments of the present disclosure are directed towards a communications system and uplink transmission method which may dynamically adapt to changing conditions of the backhaul network. A traffic engineering element (TEE) is disclosed which receives a request from at least one wireless device for uplink data transmission. The TEE then determines the backhaul conditions of the backhaul network and coordinates uplink data transmissions from at least one wireless device to one or more receivers dependent on the determined backhaul conditions.
摘要:
A method and apparatus are provided for handling uplink data traversing a backhaul in a Radio Access Network (RAN). Uplink data received at access nodes of the RAN is processed by processing functions separate from the access nodes. The processing functions provide processed data for use, by further nodes, in decoding of the information transmitted from client devices. Processing can include one or more of: regenerating uplink signals, requantizing signals, and selecting a portion of received data to forward. A scheduler which controls various access nodes and processing functions concurrently with issuance of uplink grants is also provided.

Methods, devices and systems are provided for incorporating a consideration of the quality of service (QoS) of different end-to-end paths in a network, or portions thereof, into the scheduling of uplink data and the selection of data by a user device for transmission to one or more target reception points in a network. The target reception points may be determined from a number of possible reception points by a scheduling entity or by a network access node, gateway or other entity in the network and provided to a user device along with one or more indications of QoS for an uplink scheduling grant.

A method and apparatus for balancing multipoint Radio Access Network traffic to mitigate backhaul congestion is provided. Schedulers communicate with a Traffic Engineering (TE) controller either directly or via a Virtual Link Monitor. The schedulers receive indications of data rate upper limits for virtual links overlaid onto the backhaul network, and schedule mobile device communications such that the data rate upper limits are respected. The Virtual Link Monitors maintain indications of current loading of the virtual links and provide the schedulers with operational information based on same. Scheduling is performed in view of the operational information. The Virtual Link Monitors also provide the TE controller with indications of service requirements for the virtual links, so that the TE controller can reconfigure the virtual links based on same.

Methods and apparatus for evaluating caching in a communication network are disclosed. According to embodiments, the methods and apparatus provide for dynamic evaluation of caching in a communication network, wherein a cost associated with the caching can be indicative of dynamic communication network resource demands. According to embodiments, the methods and apparatus of the instant application provide an application server is provided with a cost profile which relates to one or more of the cost of caching and the cost of link usage. The application server can thereby strategically determine how to provide the desired level of user equipment service while mitigating the cost associated with the provision of same.
