摘要： Techniques of emergency session handling in a communication network are provided, in which a packet switched network control function configured to handle emergency sessions established from a user equipment via a packet switched network access, e.g. an Emergency Call Session Control Function (E-CSCF), is associated with a switching control node of a circuit switched network. The switching control node is capable of handling emergency session established via a circuit switched network access, e.g. a Mobile Switching Center Server (MSC-S) of a mobile network. Handling of emergency sessions established via the packet switched network access is forwarded from the packet switched network control function to the associated switching control node.

摘要： A technique for performing a service domain selection in a communications network having a default service domain and at least one alternative service domain is described. According to this technique, a switching to the alternative service domain involves the invocation of a supplementary service that is provided as a supplement to a basic service. A method implementation of this technique comprises steps of identifying a basic service type associated with a service request; determining if for at least one of an originating side and a terminating side of the service request the identified basic service type is linked with a subscription to the supplementary service of service domain switching; and invocating the supplementary service of service domain switching if a linking can be determined.

摘要： The present invention proposes a solution for providing IMS services and in particular mid-call services to users having circuit-switched controlled terminals and being not adapted to provide IMS services to the users. In particular, it is proposed to introduce a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of packet-based logic. The invention discusses a concept of the MAGCF handling mid-calls, which comprises identification of the received mid-call request, generating in accordance to the identified mid-call a corresponding message, tracking the status of the performed mid-calls.
摘要翻译：本发明提出了一种用于向具有电路交换控制终端并且不适于向用户提供IMS服务的用户提供IMS服务，特别是中间呼叫服务的解决方案。特别地，建议引入称为移动接入网关控制功能（MAGCF）的新节点类型。该新节点结合了蜂窝交换中心的逻辑功能和基于分组的逻辑的逻辑功能。本发明讨论了MAGCF处理中间呼叫的概念，其包括接收到的中间呼叫请求的识别，根据所识别的中间呼叫产生对应的消息，跟踪所执行的中间呼叫的状态。

摘要： The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminals. In particular, it is proposed, in order to allow IMS to take the full call and service control, to combine circuit-switched and packet-based multimedia functionality in a new node type called Mobile Access Gateway Control Function (MAGCF). In particular the present invention provides a method for ensuring that the MAGCF node acts as a roaming anchor point in order to enforce the handling of originating and terminating calls in the IMS.

摘要： A system and method of providing an enhanced service in a telecommunications network. The system includes a telecommunications network utilizing a circuit switched and packet switched access capability. The system also includes a sending User Equipment (UE) originating a call to a receiving UE. The sending UE sends an indicator informing the network to wait for further call information before proceeding with a call request towards the receiving UE. The system also includes a control node for routing calls within the network. The control node combines the call information received from the sending UE with call routing information of the call for connecting the call with the receiving UE to form a call request to the receiving UE. Upon receiving the call request message by the receiving UE, the call is connected and a media path is established between the receiving UE and the sending UE.

摘要： A method and system for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network is provided. According to an embodiment of the present invention, the media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. Responsive to a message indicating at an update of the gating at the gating function is required, the gating function arranges for a new gating to be opened while keeping the old gating open. The gating function determines when the media has been switched to the new path. Responsive to the determination, the gating function arranges for the old gating to be closed.
