In one aspect, a method performed by a first node in a first communications network is provided. The method includes receiving first trace data for the first communications network, in which the first trace data comprises one or more first attributes. The method further includes replacing the one or more first attributes in the first trace data with corresponding second attributes to provide second trace data, sending the second trace data to a second node for performing network monitoring and receiving, from the second node, first network monitoring information for the first communications network based on the second trace data, in which the first network monitoring information comprises the one or more second attributes. The method further includes replacing at least one of the second attributes in the first network monitoring information with corresponding third attributes, based on the first attributes, to provide second network monitoring information.

A technique for handling mobile terminating connection attempts for a mobile terminal for which a change of an association from a first routing node to a second routing node is accompanied by a Circuit Switched (CS) fallback is described. In one exemplary embodiment, a method may be performed by a Circuit Switched Fallback Interworking Function (CSFB-IWF) for handling mobile terminating connection attempts for a mobile terminal for which a change of an association from the CSFB-IWF to a Mobile Switching Center (MSC) is accompanied by a Circuit Switched Fallback (CSFB). The method may include receiving a mobile terminating connection attempt to the mobile terminal. In response to receiving the mobile terminating connection attempt, the method may include paging the mobile terminal using a Mobility Management Entity (MME). In response to paging the mobile terminal, the method may include triggering the mobile terminal to initiate a CSFB procedure. Further, the method may include determining an identity of the MSC based on a message received by the CSFB-IWF from the MSC. Also, the method may include transmitting, to the MSC, a second mobile terminating connection attempt for a CS connection to the mobile terminal.

A communication network is described, comprising: &#x2014;an access network, &#x2014;a switching control network comprising call control entities arranged for association with subscribers, where said access network is arranged for routing signalling of a given subscriber to a call control entity associated with said given subscriber, and&#x2014;an Internet Protocol based network for providing a set of services centred in said Internet Protocol based network to one or more of said subscribers, wherein said switching control network comprises a group of first call control entities and a group of second call control entities, said first call control entities are arranged for providing call control services to subscribers having circuit switched subscriptions, and said second call control entities are arranged for providing a gateway to connect to said Internet Protocol based network for subscribers having subscriptions to said set of services centred in said Internet Protocol based network, and each first call control entity has a subscriber association redirector for redirecting an association of a subscriber associated with said each first call control entity and having a subscription to said services centred in said Internet Protocol based network to said group of second call control entities.

Call control entity for a communication network

A call to a dual mode user equipment is handled by using a further access network from cellular telecommunications access network. An indication of an incoming call to the user equipment is received in a control node that the device can be reached via a device using session initiation protocol (SIP) via the cellular telecommunication access network. The device using SIP sends messages to a device that transforms messages sent according to call control signaling protocol used in the cellular telecommunications network into messages according to SIP. A route to the SIP device is linked to a device that transforms user plane according to protocol in the cellular telecommunications access network into user plane according to internet protocol and vice versa.

A technique for handling mobile terminating connection attempts for a mobile terminal for which a change of an association from a first routing node to a second routing node is accompanied by a Circuit Switched (CS) fallback is described. A method implementation of this technique comprises the following steps carried out by the first routing node: receiving a first mobile terminating connection attempt to the mobile terminal, in response to receipt of the first mobile terminating connection attempt, determining that the mobile terminal cannot be reached by the first routing node, determining an identity of the second routing node, and transmitting, to the second routing node, a second mobile terminating connection attempt for a CS connection to the mobile terminal.

The present invention is directed to a method, a switching server, a terminal device and system for providing circuit switched calls and services to terminal devices connected to a switching server via an IP Multimedia Subsystem. The method comprises a step of providing (S) a first interworking entity () in the terminal device () for interworking between circuit switched signalling messages and signalling messages related to packet switched sessions towards the IMS (). The method further comprises providing (S) a second interworking entity () in the switching server () towards the IMS (). The terminal device () is thus capable of accessing circuit switched calls and services directly from the switching server ().

Providing circuit switched calls and services over a broadband network

The application relates to SMS over LTE radio access. Several alternatives are already known, such as specified in 3GPP TS 24.247 which supports text messaging capabilities and 3GPP 23.204 which supports all existing SMS capabilities through SMS encapsulation in IP. Furthermore, 3GPP 23.272 which relates to SMS in CS fallback. A further technique is known as Generic Access Network which is under study in 3GPP 23.879 relating to CS domain services over evolved PS access and in Voice Over LTE VOLGA. The present application provides a solution for handling messages between legacy networks in the form of circuit-switched networks and IP network architecture in the form of an IP Multimedia Subsystem IMS while minimizing the efforts needed for system integration by maximal reuse of existing functionalities. This is achieved by an entity () which adapts messages received from the IMS () in such a way that the appear to a controller entity () providing conventional short message functionalities as if they have been received from a mobile terminal accessing a radio access network through a radio network interface of a circuit-switched network ().

The invention relates to a technique for selecting a framing format to be used for communications on the user plane of a layered communications network. The selection technique includes the provision of a first user plane component (such as a media gateway, MGW) bridging transmission regimes and operable in accordance with two or more different framing formats. The first user plane component is controllable via control messages received from a control plane without being responsive to any framing format instructions possibly included in the control messages. The first user plane component or any other user plane equipment in communication with the first user plane component selects the framing format to be used for user plane communications. The selected framing format is then implemented by the first user plane component for communications with a second user plane component.

To enhance quality of service management in support of application sessions running on top of bearer services, according to the present invention it is suggested to, firstly, execute a bearer service analysis in support of automatic quality of service class management. Heretofore, a bearer service carrying packet switched service traffic in support of an application session is analyzed for identification of different types of services by the application session. Related analysis information derived at an analysis unitis then forwarded to a quality of service management unit, which is adapted to automatic quality of service class management. In particular, the quality of service management unitdetermines and manages a quality of service class according to the identified quality of service class as forwarded by the bearer service analysis unit
