Abstract: The invention relates to a method for lawful interception in the case of call forwarding (AW_TlnB) in a packet-oriented telecommunications network (TK1, TK2, TK3), in which switching functions (S-CSCF1, . . . , P-CSCF3) are made available by servers. The additional aim in this telecommunications network (TK1) is to monitor connections of a subscriber (Tln B) with call forwarding (AW_TlnB) by means of lawful interception. In this case, monitoring (ÜW_TlnB) of the connections of the subscriber (Tln B) is notified to a first switching function (S-CSCF1) which is responsible for a called subscriber (Tln B) with call forwarding (AW_TlnB). The first switching function (S-CSCF1) then writes (23) a tag for said subscriber (Tln B) to a predetermined parameter of a switching protocol. Only then is signalling of call forwarding (AW-TlnB) carried out to a second switching function (S-CSCF2) which is responsible for a calling subscriber (Tln A) and the connection is then forwarded to a third switching function (S-CSCF3).

Abstract: The invention relates to a method and a device for the intermediate storage of subscriber data during the relocation of a mobile subscriber (MS) within a mobile communication network. According to the invention, once the data transmission path has moved from a switching network node (old SGSN), which is originally responsible for the subscriber, to a switching network node (new SGSN), which is to become responsible for the subscriber, the data packets are intermediately stored in the last switching network node until the subscriber data for the new data transmission path is located in the last switching network node.
