Abstract
A method includes receiving a connection request from a mobile device at a network device to allow connection of the mobile device to a core network of the first service provider through a first base station and determining whether a backhaul connection between the core network of the first service provider and the first base station is congested by the network device. The backhaul connection is determined to be congested when L is greater than (D−B)/T. When the first backhaul connection is determined to be congested, the method also includes preventing the first base station from connecting the mobile device to the core network.
Claims21
A method comprising:
- receiving, at a network device, a connection request from a mobile device to allow connection of the mobile device to a core network of a first service provider through a first base station;
- determining, by the network device, whether a first backhaul connection between the core network of the first service provider and the first base station is congested, the first backhaul connection determined to be congested when L1is greater than (D1−B1)/T1, where:
- L1is a traffic load on the first backhaul connection communicated by a second service provider providing at least two services;
- D1is a periodic data cap imposed by the second service provider on the first backhaul connection;
- B1is a total amount of data consumed by a selected one of the at least two services provided by the second service provider over the first backhaul connection during a current time period;
- and
- T1is an amount of time remaining in the current time period, measured in units of time;
- and
- when the network device determines the first backhaul connection is congested, preventing, by the network device, the first base station from connecting the mobile device to the core network.
A system comprising:
- one or more network processing devices executing a base station manager, the base station manager:
- receiving a connection request from a mobile device to allow connection of the mobile device to a core network of a first service provider through a first base station;
- determining whether the first backhaul connection between the core network of the first service provider and the first base station is congested, the first backhaul connection determined to be congested when L1 is greater than (D1−B1)/T1, where:
- L1is a traffic load on the first backhaul connection communicated by a second service provider providing at least two services;
- D1is a periodic data cap imposed by the second service provider on the first backhaul connection;
- B1is a total amount of data consumed by a selected one of the at least two services provided by the second service provider over the first backhaul connection during a current time period;
- and
- T1is an amount of time remaining in the current time period, measured in units of time;
- and
- when the base station manager determines the first backhaul connection is congested, the base station manager prevents the first base station from connecting the mobile device to the core network.
A method comprising:
- receiving, at a network device, a connection request from a mobile device to allow connection of the mobile device to a core network of a first service provider through a first base station;
- determining, by the network device, whether a first backhaul connection between the core network of the first service provider and the first base station is congested, the first backhaul connection determined to be congested when L1is greater than M×S, where:
- L1is a traffic load on the first backhaul connection;
- S is a scaling factor;
- and
- M is a maximum permitted load on the first backhaul connection;
- and
- when the network device determines the first backhaul connection is congested, preventing, by the network device, the first base station from connecting the mobile device to the core network.
