Abstract:
A method, system and gateway device enables interworking between an IP-based network and a circuit-switched network. A first address information of a first connection end located in the circuit-switched network is routed in a trigger message from the IP-based network to a gateway control function. The first and second call legs are established in parallel towards the first connection end based on the first address information, and towards a second connection end located in the IP-based network based on a second address information obtained from the trigger message. A single connection between the two connection ends is then established by connecting 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.
Abstract:
A mechanism for providing a connection from an IP-based network to a circuit-switched network, such as a GSM network is disclosed. 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 IP-based network using the routing number. Thereby, IMS-services are provided 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 which provides that conference call service. The application server 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 can then set up a circuit-switched connection as a call leg of the conference call.
Abstract:
Embodiments provide an apparatus, method, and storage medium wherein a communication identifier of a session or part of a session is provided in a package or added to a message. An apparatus may check, based on the communication identifier of package or the received communication identifier, whether or not a service indicated by the communication identifier is supported. A decision of transferring the service may be based on the communication identifier.
Abstract:
The present invention relates to a session handling entity and an application server (AS) in a communication system, the session handling entity (S-CSCF) is obtaining, from a register entity, a correlation identity for a registering private user identity of a user, transmitting the correlation identity as part of a registration procedure to the application server, and the application server initiates, based on a received session request associated with the user, at least one session request towards corresponding number of devices of the user wherein the application server is configured to check the correlation identity to ensure that not more than one session request is initiated for each device of the user.
Abstract:
The present invention relates to a session handling entity in a communication system, the session handling entity (S-CSCF) maintain a relationship between at least one public user identity, at least one private user identity and at least one contact address of a user of a communication system. Then receives from a subscription entity an indication of a correlation identity associated with the user, and stores the indication of the correlation identity as part of the relationship maintained by the maintaining means. When a session request of the user is received, determining the correlation identity for the user based on a contact address of the user included in the session request and the indication of a correlation identity associated with the user take place, and the correlation identity is included in the session request.

Abstract:
A system for updating communication services includes user equipment configured to communicate using a first communication service standard and a second communication service standard, a subscriber database, an application server, and a network device. The network device detects an update trigger corresponding to a user equipment, requests that the user equipment discontinue using the first communication service standard, and flags the user equipment as updated by communicating with the application server and the subscriber database. The network device also receives a communication from the user equipment and determines whether the communication corresponds to the first communication service standard or the second communication service standard. If the communication corresponds to the first communication service standard the network device communicates an error message to the user equipment. However, if the communication corresponds to a second communication service standard, the network device processes the communication.
Abstract:
A network entity, method and computer program product are provided for effectuating a conference session. The method includes receiving a plurality of audio measurements representative of audio levels adjacent respective participants of the conference session. At least one of the audio measurements can be received from a proximity network including a plurality of participants at one of the remote locations, the audio measurement having been identified as the highest audio measurement of the respective proximity network. After receiving the audio measurement, the audio measurements can be compared to identify the highest session measurement such that the participant associated with the highest session measurement is identified as a speaking participant, the identity being transferred to at least some of the participants of the conference session. A network entity, method and computer program product are also provided for presenting the identity of the speaking participant.
Abstract:
Disclosed is a method including having an ongoing communication session via a packet switched network, transferring said communication session from the packet switched network to a second network providing both packet and circuit switched access, and informing an application server maintaining said ongoing communication session that the communication session is to be split into a packet switched part and a circuit switched part. Also disclosed is a method in an application server, including receiving, from a first communication device, an indication that a communication session between the first communication device and a second communication device is to be split into a packet switched part and a circuit switched part, waiting for to receive transfer requests of both the packet switched part and the circuit switched part, and informing the second communication device of the split.
Abstract:
Systems, methods, apparatuses, and computer program products are provided for facilitating voice call continuity in intersystem handover. A method may include determining that a user equipment device being handed over from a packet switched network to a circuit switched network is a party to a voice call in an alerting state. The method may further include providing session state information indicating that the user equipment device is a party to a voice call in an alerting state to a network entity on the circuit switched network in response to the determination. Corresponding systems, computer program products and apparatuses are also provided.
