摘要:
The present invention relates to a mechanism for providing a connection from an packet-switched network to a circuit-switched network, such as a GSM network, wherein a temporary routing number for the circuit-switched network, such as an E.164 number, is delivered to a user terminal, and a circuit-switched call leg is established from the user terminal to the packet-switched network using the routing number. Thereby, a possibility is given e.g. to IMS network operators to provide IMS-services for end users which are located in the radio access network not having sufficient QoS required for voice over IP. In the example of a conference call service, a request for a conference call may forwarded via a data channel or data path to an application server (20) which provides that conference call service. The application server (20) then selects a conference routing number and returns the routing number to the conference host terminal via the data channel. Using the received conference routing number, the conference host terminal (15) can then set up a circuit-switched connection as a call leg of the conference call.

The present invention relates to a method, system and gateway device for ena-bling interworking between an IP-based network (30) and a circuit-switched net-work (10). A first address information (TEL URI) of a first connection end located in the circuit-switched network is routed in a trigger message from said IP-based network to a gateway control function (20). First and second call legs are estab-lished in parallel towards the first connection end based on the first address infor-mation, and towards a second connection end located in the IP-based network (30) based on a second address information obtained from the trigger message. A single connection between the two connection ends is then established by con-necting the first and second call legs. Thereby, IP-based signaling functionality can be used to add capability for subscribers located in the CS domain to be invited into conferences or calls with subscribers located in an IP-based domain, e.g. the IMS domain.

The present invention relates to a method and system for providing a service in a communication network. A service script is used to control a service execution functional unit to execute the service, wherein an execution priority is allocated to the service script based on the kind of service. Furthermore, a service logic of the service may be provided at a service execution functional unit, and the service script may comprise a service description of the service. The service execution functional unit is then controlled based on the service description to execute the service by using the service logic. Thus, the service script does not contain the service logic, and a flexible service script concept can be provided. Moreover, the signaling traffic can be reduced since the operator does not have to update service scripts for a large amount of subscribers.

Various methods for distributing a single stream of sensor data to one or more services are provided. One example method may include maintaining an association between sensor data and one or more services requesting the sensor data. The method of this example embodiment may further comprise receiving the sensor data. The example method may further comprise generating one or more copies of the sensor data. The example method may also comprise providing for distribution of the copies of the sensor data to the services requesting the sensor data, such that a copy of the sensor data is provided for distribution to each of the services requesting the sensor data. Similar and related example methods, example apparatuses, and example computer program products are also provided.

Method and apparatus, including computer program products, are provided for SRVCC emergency call support. The method may include receiving, at a mobility switching center, a first message representing a request to handover an emergency communication session from a first network to a second network. The mobile switching center may obtain a value representing an emergency session transfer number. The mobility switching center may also send a second message to the first network. The second message may initiate handover of the emergency communication session from the first network to the second network. The second message may comprise the value representing the emergency session transfer number. Related apparatus, systems, methods, and articles are Receive Session Continuity Data also described.

Methods and apparatuses for sending or receiving a page mode message include, for example, sending a page mode message using a session mode message mechanism with an indication indicating that a session mode is for the page mode message. A session is established for carrying the page mode message by message session relay protocol.

The present invention relates to a method and system for inspecting a session in a packet data network, wherein a set-up message is selectively routed to a predetermined server node (4001, 4002) and processed there. A media resource function (3021, 3022) is controlled based on the processing so as to bind incoming and outgoing data streams in order to relay the session via the media resource function. Thereby, a mechanism for providing charging, filtering and logging services for sessions, such as peer-to-peer chat sessions, is provided without requiring any new network entity or modification of existing network specifications.
摘要:
A system, apparatus and method for establishing circuit-switched (CS) communications in packet-switched (PS) multimedia networks such as IMS, and providing services via the PS networks to CS domain users. A dialog is established between terminals through the PS multimedia network. A service is provided to at least one of the terminals by way of the dialog. CS bearer information, including an indication that a communication flow is requested via a CS network, is communicated between the terminals by way of the dialog. A communication flow via the CS network is effected between the terminals as directed by the CS bearer information. IMS or other PS multimedia network services can thus be provided to users otherwise communicating via the CS-domain.

Methods, apparatuses, and computer program products for submitting and/or delivering a SMS between user equipment without MSISDN are provided. One method includes storing the SIP-URI and IMSI for a device sending a SMS. The method may further include receiving a SMS from the sending device. In an embodiment, the TP-DA field of the MO-SMS is filled with value(s) that indicates the recipient UE is addressed without MSISDN, the R-URI is set to PSI, and the “to header” is set to the receiving device's SIP URI. The method may include retrieving the receiving device's SIP URI from the “to header,” and querying the receiving device's HSS for the IMSI and routing information of the receiving device. The method may then include delivering the SMS to the receiving device directly or delivering the SMS to the receiving device via the SMSC.
