Embodiment Construction

[0022] Particular embodiments relate to methods, apparatus and computer program products for improved information routing in radio networks.

[0023] A radio network can be constructed with communicating nodes that need to select (or have selected) channels or physical radio resources to communicate with each other. For example, networks such as figure 1 The network 100) can be constructed from a plurality of connected nodes (such as nodes 110, 120, 130, and 140), where information is carried along specific routes in the network. These routes (or "hops") may for example consist of paths 102, 104, 106 and / or 108, such as figure 1 shown in the example. Typically, information will flow in network 100 to and from aggregation points, shown as nodes 140 in this example. The aggregation node 140 may eg be connected to the mobile core network, to the wireless device, to one or more control units.

[0024] Frequently, the radio spectrum associated with such networks and communicati...

Abstract

Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller (210) and radio resource manager (220). A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.

Description

technical field [0001] The present disclosure relates generally to radio access networks, and more particularly to channel assessment, channel negotiation, and routing of information through radio access network nodes. Background technique [0002] Dense deployments of base stations and wireless access nodes are being used to cope with the significant growth in wireless data traffic. One implementation is an ultra-dense network (UDN), where wireless nodes within the network are deployed in large numbers. In these networks, multiple routes between pairs of nodes may be established, and thus a routing function may be required to distribute routes and establish network topology. [0003] Often, various networks and devices will be required to share the available wireless spectrum. For example, many wireless networks operate in unlicensed frequency bands, where certain regulatory limits on bandwidth, power spectral density, and deployment characteristics are used to enable sha...
