Abstract: A wireless device derives first paging occasions of a first public land mobile network (PLMN) based on an international mobile subscriber identity (IMSI) of the wireless device and second paging occasions of a second PLMN. The wireless device determines a collision between the first paging occasions and the second paging occasions. Based on determining the collision, the wireless device sends, to a core network node of the first PLMN, a requested IMSI offset value for offsetting the IMSI of the wireless device. the wireless device receives, from the core network node, an accepted IMSI offset value for offsetting the IMSI of the wireless device. The wireless device monitors third paging occasions of the first PLMN. The third paging occasions are derived based on an alternative IMSI equal to a sum of the IMSI of the wireless device and the accepted IMSI offset value.

Abstract: Techniques for identifying sources of degradations within a PON include detecting that an optical profile of a segment of the PON is outside of a designated operating range, and comparing the drift over time of the segment's optical profile with respective drifts over time of optical profiles of other PON segments, each of which shares an OLT or a last mile termination unit with the segment as a common endpoint. Each segment's optical profile corresponds to characteristics of optical signals delivered over the segment (e.g., attenuation, changes in frequencies, changes in power outputs, etc.). The differences between the segments' drift(s) over time are utilized to determine the source of a degradation within the PON, and may be utilized to identify a particular component of the segment (e.g., the OLT, the last mile termination unit, or an optical fiber included in the segment) as being the source of the degradation.
