Group based reporting of ue related information

A method performed by a second network node, the method comprising:

• receiving from a first network node a request message for requesting first user equipment (UE) related information, wherein the request message includes a first group UE identifier (ID) identifying a first group of one or more UEs for which the first UE related information is requested;
• and
• after receiving the request message, transmitting towards the first network node a reporting message which includes first UE related information for one or more UEs included in the first group of UEs, wherein
• the reporting message includes one or more performance measurement results and one or more series IDs each of which identifies a UE associated with each of the one or more measurement results.

A first network node, the first network node being configured to:

• transmit towards a second network node a request message for requesting first user equipment (UE) related information, wherein the request message includes a first group UE identifier (ID) identifying a first group of one or more UEs for which the first UE related information is requested;
• and
• after transmitting the request message, receive a reporting message which includes first UE related information for one or more UEs included in the first group of UEs, wherein
• the reporting message includes one or more performance measurement results and one or more series IDs each of which identifies a UE associated with each of the one or more measurement results, and the reporting message was transmitted by the second network node.
