Use Case identified : Mobile Backhauling CESoPSN PW used to carry the 2G traffic (mainly voice traffic) CESoPSN specifications Inherent trade-off between bandwidth consumption and latency => The Operator must setup CESoPSN PW so as to carefully match the PW capacity to the actual payload. Problem Statement when upgrading the network (e.g.: introduction of new cells, new services…) the capacity of particular PWs needs to grow without interrupting ongoing voice services used by numerous customers. Although interface parameter update will generally be a rare event for most applications, it is still highly recommended not to negatively impact customer services. Solutions so far proposed to increase a CESoPSN PW capacity Teardown the existing PW, and setup a new one with the new appropriate parameters Cons: service disruption Setup an additional PW for the specific additional bandwidth Cons: as many pw as updates required Problem Statement |
