摘要:
A communication network comprising at least an application server means (APSE), a subscriber information register means (HSS), a call state control functional entity (CSCF), and a service portal (SP), wherein the application server means (APSE) is connected to the service portal (SP) and to the call state control functional entity (CSCF), the service portal is further connected to the home subscriber server means (HSS), and the subscriber information register means (HSS) is further connected to the call state control functional entity (CSCF). In connection with the proposed network architecture, methods for handling service scripts within the network with regard to creation and storage of service scripts, provisioning the service scripts for a user, distribution of the scripts in the network and execution of the scripts during call processing are also described.

A new function is added into switching centres (CPS) to facilitate the adding of various services, the function transmitting the service data structure of a non-standard service to a system entity responsible for the service. The system entity is identified on the basis of an indicator associated with the service data structure.

An emergency telephone call is supported and routed to a Public Safety Answering Point (PSAP) in an IP based packet switched wireless communications network. An activate PDP context request is sent from a user equipment to the network. A parameter in the activate PDP context request indicates that the PDP context will be used to transfer an emergency call. An activate PDP context accept message is returned from the support node to the user equipment. The activate PDP context accept message acknowledges the activate PDP context request message and provides the address of a call state control function. A call setup request transferred to the call state control function includes the Service Area Identity (SAI). The call state control function selects a PSAP based, at least in part, on the SAI included in the call setup request and forwards the emergency call to the selected PSAP.

摘要:
An object of the invention is a method for logging out a user of an application-layer service, the service being implemented with the aid of a user's wireless terminal, the terminal implementing a protocol stack comprising an application layer, and which application layer comprises a set of service applications for implementing application-layer services, and an application-layer control and signalling protocol, such as SIP (Session Initiation Protocol), for logging the user on application-layer services in a network and for logging the user out of application-layer services. According to the method, when switching off the wireless terminal, the user is logged using the application-layer control and signalling protocol out of at least one application-layer service of which the user has not logged out, or a conditional request for logging out the user is sent to the network.
