Patent ID: 8549358

Claim:
A method for performing session establishment management, comprising: detecting, via a processor, an evolved packet system establishment success rate that is measured over a period of time falling below a threshold; performing, via the processor, an analysis on a bearer portion in response to the detecting, wherein the performing the analysis comprises: isolating a cause of the evolved packet system establishment success rate falling below the threshold to one of: a portion of a signaling bearer or a portion of a packet data network bearer, wherein the signaling bearer comprises a signaling radio bearer and an S 1 signaling bearer and the packet data network bearer comprises an S 1 data bearer and an S 5 /S 8 data bearer, wherein the isolating comprises: calculating an establishment success rate for the signaling radio bearer, the S 1 signaling bearer and the packet data network bearer; and determining which of the establishment success rate for the signaling radio bearer, the S 1 signaling bearer or the packet data network bearer has a lowest establishment success rate; and performing a trouble management on an isolated portion from the isolating that is responsible for causing the evolved packet system establishment success rate to fall below the threshold; and associating, via the processor, a root cause that contributed to the evolved packet system establishment success rate falling below the threshold.
