Abstract
A mobile carrier may selectively offload backhaul data traffic between cell sites and the core network to existing alternative relay networks to increase available backhaul bandwidth to meet higher data traffic demands without adding additional network ‘infrastructure. Data traffic may be offloaded from a cellular network to the alternative relay network based on at least one of a bandwidth capacity of the alternative relay network, a bandwidth availability of the alternative relay network, or a data class of the data. The amount of data that is offloaded to the alternative relay network may then be adjusted based on a blocking probability that is calculated for the alternative relay network.
Claims20
A computer-readable medium storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising:
- offloading a transmission of an amount of data between a cell site and a core network from a cellular network to an alternative relay network for a predetermined time interval;
- calculating a blocking probability for the alternative relay network based on quality of service metrics of the alternative relay network;
- reducing the amount of data to be offloaded in a subsequent time interval by a decrement amount to produce an adjusted amount of data in response to determining that the blocking probability exceeds a threshold;
- and
- increasing the amount of data to be offloaded in a subsequent time interval by a an increment amount to produce the adjusted amount of data in response to determining that the blocking probability does not exceed the threshold.
A computer-implemented method, comprising:
- determining that a transmission of an uplink data packet from a cell site to a core network is to be offloaded from a cellular network to an alternative relay network based on at least one of a bandwidth capacity of the alternative relay network, a bandwidth availability of the alternative relay network, or a data class of the data;
- and
- routing the uplink data packet from the cell site to the core network using the alternative relay network, the alternative relay network being a relay network that is operated by a mobile carrier that operates the cellular network or an independent relay network that operates independently from the mobile carrier.
A mobile telecommunication network, comprising:
- one or more processors;
- and
- memory storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising:
- determining that a transmission of a downlink data packet from a core network to a cell site is to be offloaded from a cellular network to an alternative relay network based on a transmission route of an uplink data packet that is associated with the downlink data packet;
- and
- routing the downlink data packet from the core network to the cell site using the alternative relay network, the alternative relay network being a relay network that is operated by a mobile carrier that operates the cellular network or an independent relay network that operates independently from the mobile carrier.
