Selective establishment of radio access bearers to support simultaneous voice and data communications in a mobile telecommunications network

A method for selectively establishing radio access bearers, the method comprising:

• collecting an uplink transmit power statistic for a mobile device during a voice session occurring over a first radio access bearer established between the mobile device and a mobile telecommunications network;
• receiving a request to initiate a data session between the mobile device and the mobile telecommunications network;
• in response to receiving the request, calculating an available uplink transmit power from the uplink transmit power statistic;
• and
• determining if a second radio access bearer configured to simultaneously support the voice session and the data session should be established based at least in part upon the available uplink transmit power and a comparison of the available uplink transmit power to a thresholding algorithm, wherein the thresholding algorithm employs a weighting function that utilizes a plurality of statistics comprising the uplink transmit power statistic, each of the plurality of statistics being weighted by a certain factor to calculate a weighted result that is used to determine if the second radio access bearer should be established.

A computer storage medium having computer readable instructions stored thereupon that, when executed by a mobile device, cause the mobile device to perform operations comprising:

• collecting uplink transmit power statistics for the mobile device;
• calculating a mean uplink transmit power from the uplink transmit power statistics;
• calculating a standard deviation from the uplink transmit power statistics;
• calculating a value for the mean uplink transmit power plus the standard deviation;
• determining if the value calculated for the mean uplink transmit power plus the standard deviation at least meets a threshold value;
• allowing establishment of a radio access bearer if the value does not at least meet the threshold value;
• and
• denying establishment of the radio access bearer if the value at least meets the threshold value.
