Abstract
Detection and prevention of heavy congestion in a wireless network is disclosed herein. Radio links are monitored and if the number of radio links reaches a first threshold level, one or more network parameters are modified in order shrink a cell footprint and/or to control cell reselection. The monitored radio links can be downlink circuit switched and packet switched radio links. Alternatively or additionally, an uplink noise level can be monitored and if the uplink noise level reaches a second threshold level, the one or more network parameters can be modified, even if the number of radio links are not at the threshold level.
Claims19
A system, comprising:
- a memory to store executable instructions;
- and
- a processor, coupled to the memory, that facilitates execution of the executable instructions to perform operations, comprising:
- determining a quantity of downlink radio links sent from network devices of a set of network devices to one or more mobile devices within a geographic coverage area, comprising excluding soft handover radio links from the quantity of downlink radio links, wherein the downlink radio links comprise circuit switched radio links and packet switched radio links;
- determining that a measured number of downlink radio links satisfy a first condition;
- and
- adjusting a network parameter of a network device of the set of network devices comprising reducing the geographic coverage area in response to the first condition being determined to be satisfied.
A method, comprising:
- quantifying, by a system comprising a processor, a number of downlink radio links excluding soft handover radio links;
- determining, by the system, that the number of downlink radio links satisfies a first condition;
- and
- modifying, by the system, a first network parameter related to a geographic coverage area or a second network parameter related to cell reselection in response to the determining that the first condition is satisfied.
A non-transitory computer-readable device storing executable instructions that, in response to execution, cause a system including a processor to perform operations, comprising:
- initiating a capacity setting for network parameters of a set of network devices;
- measuring a number of downlink radio links of the set of network devices, wherein soft handover radio links are excluded from the number of downlink radio links;
- measuring an uplink noise level received by the set of network devices;
- determining that the number of downlink radio links satisfies a radio link condition or the uplink noise level satisfies a noise level condition;
- and
- increasing a received signal level parameter and a cell reselection parameter in response to the radio link condition being determined to be satisfied or in response to the noise level condition being determined to be satisfied.
