Abstract: When the operator of a mobile communication system applies one of: “dynamic Tracking Area List” or “smart paging” for more efficient paging, the “real” size of the Tracking Area, i. e., the number of cells over which a S1AP-paging is broadcasted on average, becomes difficult to calculate in real time; A method of determining tracking area size information is therefore proposed comprising: obtaining the average number of paging records per cell, and dividing it by average number of RRC-Connection-Setup, for terminated calls, per cell; the result is proportional to the real TA size; the obtained value is proposed as a new KPI, Key Performance Indicator.

Abstract: Correlation of information related to network operations may be useful in many communication systems. For example, certain wireless communication networks may benefit from alarm correlation in network function virtualization environments. A method can include correlating alarms within a lower layer of a network function virtualization environment. The method can also include forwarding at least one of the correlated alarms to an entity managing an upper layer of the network function virtualization environment for further correlation with upper layer alarms.

Abstract: Methods, apparatus and computer program products are disclosed for enhancing mobility robustness optimization in self optimizing networks. Neighbor relation information indicating relations between a handover source cell and candidate handover target cell(s), each including a first counter indicating events of an unsuccessful handover of a user equipment from the handover source cell to one candidate handover target cell, and a second counter indicating events of connection re-establishment attempt of the user equipment to the candidate handover target cell after an unsuccessful handover to another cell. A first candidate handover target cell to which handover of the user equipment was unsuccessful and a second candidate handover target cell to which the user equipment has re-established a connection, out of the candidate handover target cells, are determined. The first counter and/or the second counter of the neighbor relation information concerning the determined first and second candidate handover target cells is updated.

Abstract: There are provided measures for inactivity timer evaluation. Such measures exemplarily comprise monitoring a communication related state, determining, upon a first state change indicative of a start of a communication, a duration amount of a period between said first state change and a preceding second state change indicative of an end of a preceding communication, and adjusting a control value based on a distribution of a plurality of determined duration amounts.

Abstract: A method and apparatus may include transmitting a scaling request. The scaling request comprises a request for virtualized network function expansion or virtualized network function contraction. The scaling request is transmitted to a second network node. A first domain is directed to application level details. A second domain is directed to virtualization level details. The scaling request comprises: (1) a relative target capacity that is generic to both the first domain and the second domain, (2) an absolute target capacity that is specific to the first domain, or (3) a relative target capacity that is specific to virtualized network function level targets. The method may also include receiving a notification that a virtualization network function has been updated based on the transmitted scaling request.
