Abstract: A node at a server side of a client-server system receives a request corresponding to a user account maintained in the server side. If login credentials in the request are valid, the node generates a session and a set of values including session metadata, a timeframe, and a signature associated with the session, wherein the signature is generated from the session metadata, the timeframe, and a salt that is shared among nodes at the server side. The session and the set of values are sent to a client from which the request originated. An additional node at the server side receives a request to access the session and obtains values from a value included in the request corresponding to the signature associated with the session using the salt. Session access is granted or denied based at least in part on whether the obtained values match the session metadata and timeframe.

Abstract: Various communication systems may benefit from methods, apparatuses, and systems for data collection. For example, wireless communication systems of the third generation partnership project (3GPP) may benefit from data collection in network management layer coverage and capacity optimization. For example, a method may include sending performance measurement job activation indicating that minimization of drive test data is to be collected (in an alternative, the job can be configured to indicate that non-MDT data is to be collected). The method may also include receiving performance measurements in response to the job activation.

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.

The user input corresponds to a request for a task to be performed by each entity of a set of entities from a virtualization environment. The request for the task is sent to the set of entities. The computing device receives feedback from each entity of the set of entities. The feedback corresponds to the progress of each entity's individual task for the request. The computing device aggregates the feedback from the set of entities into a single parent task, and sends only the reference to the parent task to the client device for display.
