摘要： An apparatus and a method are configured to host subscription data of communication elements of a communication network attached to virtualized network functions on the basis of a stored indication, and storing an indication for the virtualized network functions indicating whether the virtualized network functions are de-instantiated. A message directed to a virtualized network function is received and processed, and the method then checks whether the virtualized network function is indicated to be still instantiated or not. If the results of the checking is that the virtualized network function is de-instantiated, a simulation process is conducted.

摘要： There are provided measures for handling a signaling message on a data plane in a software-defined architecture. Such measures may exemplarily comprise establishing, in a control plane entity, an instruction for reacting to a specific incoming signaling message on the data plane with a corresponding outgoing message on the data plane, providing the established instruction from the control plane entity to a data plane entity for instructing the data plane entity to react to the specific incoming signaling message with the corresponding outgoing message in accordance with the established instruction, and reacting, in the data plane entity, upon detection of the specific incoming signaling message on the data plane, to the specific incoming signaling message on the data plane in accordance with the provided instruction.

摘要： A mechanism for improving a reliability of a virtual network and resources used. At a virtual network operator level, a request for providing resources for the virtual network is sent towards an infrastructure provider level. The request includes an indication regarding a required availability and reliability level which is to be achieved by the resources of the virtual network. At an infrastructure provider level the request is processed in order to determine the required availability and reliability level, and it is checked whether the required availability and reliability level is achievable for the resources to be provided for the virtual network. A result (confirmation or denial) of the check is sent back to the virtual network operator level.

摘要： 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). In this case, this third switching function (S-CSCF3) then identifies and initiates the monitoring (ÜW_TlnB) of the called subscriber (Tln B) on the basis of the predetermined parameter of the switching protocol. The major advantage of the method according to the invention is that it is still possible for a department or authority who is empowered to carry out monitoring to monitor (ÜW_TlnB) the contents of connections in a packet-oriented telecommunications network (TK1) even in the case of call forwarding (AW_TlnB).
摘要翻译：本发明涉及一种在面向分组的电信网络（TK1，TK2，TK3）中的呼叫转移（AW_TlnB）的合法拦截方法，其中交换功能（S-CSCF1，...，P-CSCF3）由服务器提供。该电信网络（TK1）中的额外目标是通过合法拦截监视用户（Tln B）与呼叫转移（AW_TlnB）的连接。在这种情况下，用户（Tln B）的连接的监视（ÜW_TlnB）被通知给负责呼叫转移（AW_TlnB）的被叫用户（Tln B）的第一交换功能（S-CSCF1）。第一切换功能（S-CSCF1）然后将（23）所述用户（Tln B）的标签写入切换协议的预定参数。只有在进行呼叫转移（AW-TlnB）的信号发送到负责主叫用户（Tln A）的第二交换功能（S-CSCF2），并且该连接然后被转发到第三交换功能（S-CSCF3 ）。在这种情况下，第三切换功能（S-CSCF3）根据切换协议的预定参数来识别并发起被叫用户（Tln B）的监视（ÜW_TlnB）。根据本发明的方法的主要优点是，即使在分组导向的电信网络（TK1）中，有权进行监视的部门或机构仍然可以监视（ÜW_TlnB）连接的内容呼叫转移情况（AW_TlnB）。
