A device is configured for communications over an IP network. The device comprises a user interface, a memory interface for accessing information media files stored in a memory in the device or associated with the device, and a media file streamer. The device is configured to receive an instruction from the IP network during establishment of a call, during a call, or at termination of a call, the instruction identifying one or more of the media files. The device is configured to access the identified media file from the memory via the memory interface and to stream the identified media file to convey the information in the media file via the user interface.

Device-resident media files

Methods and devices for providing a device access to a General Packet Radio Service (GPRS) network are described. The GPRS network comprises a control node for controlling the access. The control node performs the steps of receiving a service request from the device, the service request comprising a device identifier, obtaining a group profile comprising a group identifier identifying a plurality of devices, selecting the group profile for serving the device, if the device identifier corresponds to the group identifier, and establishing a connection based on the group profile in accordance with the service request.

Providing access to a GPRS network

According to an aspect of the present disclosure, a method is disclosed for a SIPIMR node to withdraw from a SIP session set-up loop by replying a redirect message to the SIP Invite sending node. The redirect message contains information for setting up alternative SIP session, said information being available in the SIP Invite receiving node. This information is usable by the SIPIMS node for establishing an alternative SIP session as well as information needed by other nodes and applications further on in the SIP session set-up loop. The SIPIMS node is specially adapted to retrieve the information from the redirect message for establishing a new SIP session based on and containing the information from the redirect message. Several implementations are given for use in an IP Multimedia Subsystem of a telecommunication network.

Method and system for transfer of call control

According to a first aspect of the present invention there is provided a method of handling an IP Multimedia Subsystem, IMS, session establishment request received from a calling party at a Multimedia Telephone Application Server, MMTel AS, within an IMS network from a Serving Call Session Control Function, S-CSCF, over an IMS Service Control, ISC, interface. The method comprises, within the MMTel AS: a) determining that said request is an originating call case request; b) establishing a first Multimedia Telephone, MMTel, service engine instance within the MMTel AS and using that first MMTel service engine instance to handle the request according to an originating call case; c) determining whether or not a called party associated with said request is served by said MMTel AS and, if so, establishing a second MMTel service engine instance within the MMTel AS, passing the request to said second MMTel service engine instance, and using the second MMTel service engine instance to handle the request according to a terminating call case; and d) forwarding said IMS session establishment request over said ISC interface to said S-CSCF, or to another S-CSCF serving the called party.

Session establishment using one multimedia telephony (MMTEL) application server

Combinational networks provide simultaneous connectivity via networks of different network type between user equipment. For communication sessions on different network types, belonging to the same user equipment, a correlation check is enabled by introduction of an identifier denoted as Combinational Call Indicator (CCI). This CCI identifier in combination with the known Calling Line Identity (CLI) identifier enables user equipment and other and network entities to perform a correlation check between ongoing, or to be established, CScalls and PS-sessions. A user equipment, setting up a related communication session, sets the CCI identifier and provides the CCI identifier during the communication session setup towards the receiving user equipment or network entity, which is enabled to check whether the last received communication session is correlated to the earlier established session due to the presence of the CCI identifier.

Method and device for providing correlation means in hybrid telecommunication networks

A telecommunication system for transferring SMS messages between a first terminal and at least one second terminal or intelligent network service. The system comprises a mobile telecommunication system () and one or more mobile network switching nodes () acting as gateway between the mobile telecommunication system () and the remainder of the telecommunication system for sending and receiving SMS messages to and from mobile terminals (-), coupled to an Intelligent Network control node () and one or more message servers (). The Intelligent Network control node (), is coupled to the mobile network switching nodes () and the message servers () for providing Intelligent Network services in the telecommunication system. One or more message servers (), routing messages in the telecommunication system are coupled to the Intelligent Network control node () and the mobile network switching nodes (). The Intelligent Network control node () and the mobile network switching nodes () are adapted to exchange the SMS messages directly (). Further there is provided a method for transferring SMS messages in such a telecommunication system, between the Intelligent Network control node () and the mobile network switching nodes () among others for interactive message sequences.

The redirect message contains information for setting up alternative SIP session, said information being available in the SIP Invite receiving node. This information is needed by the SIP invite sending node for establishing an alternative SIP session as well as information needed by other nodes and applications further on in the SIP session set-up loop.

A Service Interaction Manager in a Packet Based Multimedia System (PBMS) for initiating a session with a terminal utilizing a temporary virtual subscription when the terminal does not have a subscription with the PBMS. A table stores temporary virtual subscriptions. A Coupling Function connected with a Network Access Gateway and the table utilizes the table to select an available virtual subscription and to store in the table, a temporary association between an identifier of the terminal and the available virtual subscription. A Correlation Function connected with a requested service, the table, and a PBMS access gateway receives from the PBMS access gateway, a session start request message with the terminal identifier, and utilizes the table to correlate the session start request message with the available virtual subscription based on the terminal identifier.

Method and apparatuses for making use of virtual IMS subscriptions coupled with the identity of a non SIP compliant terminal for non-registered subscribers

Means and methodology for a telecommunication network are provided that allow using an IMEI of mobile terminal as destination or identification instead of the regular IMSI or MSISDN. This capability of the telecommunication network is provided by maintaining a set of coupled pairs of IMEI and IMSI/MSISDN. Operational messages in the telecommunication network having an IMEI address as destination or identification are translated by the appropriate IMSI or MSISDN depending on the message type, from a coupled pair having the same IMEI. Means is provided with a STP capable of maintaining the set of coupled pairs. Further several implementations are provided using the IMEI addressing capability.

Method and system for addressing a mobile terminal

A method of routing a call setup request to a destination serving node serving a destination subscriber in an IMS network. The method comprises the steps of a switching node receiving the call setup request having a destination number of the destination subscriber, the switching node querying a number conversion database node for destination routing information using the destination number. The method further comprises the steps of the number conversion database node querying subscriber information for destination serving node information related to the destination number, the number conversion database node receiving destination serving node information from the subscriber information, the number conversion database node replying to the switching node with destination routing information comprising the destination serving node information and the switching node routing the call set up request to the destination serving node using the destination serving node information.
