Abstract

A system and method for detecting and correcting uplink-only problems is disclosed. The system comprises one or more of the following modules: uplink problem detection module, maximum permissible limit module, and uplink improvement calculation and actions module. The uplink problem detection module detects uplink-only problems using values of one or more parameters related to bearer performance. For instance, the uplink problem detection module continuously monitors the uplink performance by checking uplink transmission error and when a threshold is crossed, declares an uplink problem. The maximum permissible limit module limits the actions by uplink improvement calculation and actions module so that other parts in the system are not negatively affected. The uplink improvement calculation and actions module determines and performs the actions to improve the uplink transmission error situation detected by the uplink problem detection module.

Claims20

Dependent claims

At least one machine-readable medium, excluding transitory signals, having stored thereon instructions, which when executed by at least one machine, identifies and corrects uplink-only problems between bearers that are communicatively coupled to base stations in a telecommunications network by causing the at least one machine to:

determine values of performance parameters in a set of selected performance parameters related to a set of bearers;
detect at least one uplink-only problem associated with the set of bearers based on the determined values of a subset of performance parameters in the set of selected performance parameters;
rank bearers in the set of bearers based on bearer-specific parameters comprising an associated allocation and retention policy (ARP) priority level,
wherein when two or more bearers in the set of bearers have a similar rank, modify ranks of the two or more bearers based on a resource type of the two or more bearers;
select a subset of the ranked bearers;
transmit at least one uplink problem corrective action to be performed at a first set of bearers in the subset of the ranked bearers,
wherein the least one uplink problem corrective action comprises transmitting, to a subset of bearers in the set of bearers, updated values for parameters in a set of updated parameters;
in response to transmitting the at least one uplink problem corrective action, determine updated values of the performance parameters in the set of selected performance parameters related to the set of bearers;
determine whether the at least one uplink-only problem is fixed based on the determined updated values of the performance parameters;
when the at least one uplink-only problem is fixed, readjust values of at least one performance parameter in the set of selected performance parameters;
and
when the at least one uplink-only problem is not fixed:
when bearers in the subset of ranked bearers qualify for at least one second level of uplink improvement action, transmit the at least one second level of uplink improvement action to be performed at a second set of bearers in the subset of the ranked bearers.
