FIRST NETWORK NODE AND METHOD IN A COMMUNICATIONS NETWORK

A method performed by a first network node in a Visited Public Land Mobile Network, VPLMN. The first network node is related to Lawful Intercept, LI, in the VPLMN. The first UE is associated with a Home Public Land Mobile Network, HPLMN and is located in the VPLMN. When the communication is started, the first network node receives a first Session Initiation Protocol, SIP, message from a gateway node in the VPLMN. The first SIP message includes first data related to starting of the communication. The first network node determines, based on analysing the first data, first communication data. The first network node sends a first request to a second network node operating in the VPLMN. The first request includes the determined first communication data and requests a first action to be performed by the second network node.
