There are provided measures for conflict resolution in a network virtualization scenario, wherein a virtualized network function is utilized by a first virtualized network service managed by a first network component and a second virtualized network service managed by a second network component. The measures comprise requesting, by the first network component, an alteration of the virtualized network function, transmitting information indicative of the alteration of the virtualized network function to the second network component, and determining when the alteration of the virtualized network function impacts the second virtualized network service.

Conflict resolution in network virtualization scenarios

There are provided measures for resource placement control in network virtualization scenarios. Such measures exemplarily comprise, in a network virtualization scenario, determining, by a first network entity managing a virtualized network function, constraints related to said virtualized network function, transmitting, by said first network entity, information indicative of said constraints to a second network entity managing resource capacity in said network virtualization scenario, and deciding, by said second network entity, resources or resource capacity to be allocated for said virtualized network function, based on said information indicative of said constraints.

Resource placement control in network virtualization scenarios

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.

Method and apparatus for virtualized network function scaling that is initiated by network management and/or element management

Systems, methods, apparatuses, and computer program products for virtualized network function (VNF) decomposition are provided. An embodiment of the invention includes to first decompose the Network Function into smaller blocks: application, platform, and resources (i.e., compute, network, and storage), then manage the decomposed application and platform parts by separate entities (e.g., EM/VNFM). This decomposition may be applied to the Network Elements (i.e., the current building blocks of telecommunication networks) and to the VNFs.

Method and apparatus for virtualized network function decomposition

Systems, methods, apparatuses, and computer program products for moving VNF instances between network service instances are provided. One method includes, when a real network service is being instantiated, transmitting or receiving a move virtualized network function (VNF) operation to move at least one virtualized network function (VNF) instance from a source network service to a target network service.

Methods and apparatuses for moving virtualized network function instances between network service instances

The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding managing the graceful termination of a virtualized network function (VNF) instance. The method comprises receiving a request for a graceful termination of a virtual network function instance, transmitting the request for the graceful termination of the virtual network function instance to an element manager, checking, whether a confirmation that the virtual network function instance to be terminated has been taken out of service, is received, and if the confirmation is received, terminating the virtual network function instance.

Managing the graceful termination of a virtualized network function instance

The present invention addresses method, apparatus and computer program product for resource management within a distributed system in a core network element, comprising organizing computing resources of the core network element into sets, wherein a first set is always active, setting an upper threshold and a lower threshold for the load of the sets, wherein the sets in operation are loaded as long as the average load of the sets in operation reaches the upper threshold, and when the upper threshold is exceeded, a new set is activated, whereas, when the load thereof falls below the lower threshold, the last activated set is deactivated, assigning a priority number to each set, segmenting an interval of random numbers for randomizing a request distribution in subintervals which are allocated to the computing resources of the active sets, wherein the length of each subinterval is determined based on the priority number of the set of the respective computing resource, and allotting a random number out of the interval to an incoming request, and forwarding the request to such computing resource which belongs to the subinterval that contains the allotted random number.

Optimized resource management in core network elements

According to an embodiment there is provided a method comprising; collecting a first type of measurement and a second type of measurement, said first and second types of measurement being used together by an entity; and causing values of said first type of measurement to be sent with associated values of said second type of measurement to be sent.

Method and apparatus for use in MDT data collection

It is provided an apparatus, comprising selecting means adapted to select one set of parameters/values out of a first set of parameters/values and a second set of parameters/values received in an activation message related to a trace session of a subscriber or a terminal, wherein the selected set of parameters/values corresponds to the trace session in a first domain of the apparatus and the other set of parameters/values corresponds to the trace session in a second domain different from the first domain; providing means adapted to provide the selected set of parameters/values and an identifier to a tracing device for performing the trace session in the first domain, wherein the identifier is received in the activation message and related to the trace session.

Tracing inter-RAT events

A method, apparatus, system, and computer-readable medium is provided for performing RLF functionality within a trace functionality. As part of trace functionality, RLF information, in the form of one or more RLF reports, is collected. When MDT information is also collected as part of trace functionality, the RLF information and the MDT information is correlated.

Minimization of drive tests data and radio link failure information correlation

Communication networks in general may benefit from appropriate policy based management. More particularly, heterogeneous networks or HetNets may benefit from methods for policy based management. A method according to certain embodiments includes detecting a reportable event. The method also includes determining whether or how to report the event based on a probability criterion. The method further includes taking an action with respect to reporting the event based on whether the probability criterion is met.

Method for heterogeneous network policy based management

A user equipment performs measurements logging which has been defined for a scheduled area belonging to a network of a mobile communications network, the measurements including information about performance of the scheduled area. In case the user equipment connects to an area of areas of the mobile communications network which belongs to a network different from the network of the scheduled area, the user equipment prevents transmission of the logged measurements.

Measurements logging and transmission at a user equipment of a mobile communications system

Embodiments of the invention include a method for collecting RLF data in a wireless network. The method may include receiving, by a first radio access node, RLF data related to a connection failure experienced by a UE. The method may then include determining whether the RLF data satisfies at least one condition and, when it is determined that the RLF data satisfies the at least one condition, sending the RLF data to at least one of a second radio access node and an RLF data collection entity. In one embodiment, the RLF data may be received from a second radio access node or the UE.

Radio link failure report filtering

A communication network comprises a management system, a core network element, and a radio access network element. The core network element may be a subscriber database or a mobility entity. It is capable of: receiving consent information; receiving from the management system a measurement reporting activation in a network; checking whether at least part of the activation request applies to a subscriber for whom consent information consenting to measurement reporting has been provided; and in the event that consent information consenting to measurement reporting has been provided, ensabling the activation request by communicating with the radio access network element so that measurement reporting in respect of that subscriber may take place. The measurement reporting activation may be for subscriber-based or area-based measurements to be made.
