Abstract:
Local discovery of mobile network services involves coupling a communications device to a local network segment of a mobile data network. An announcement is sent from the communication device and/or a network entity (such as a network proxy) describing a service available via the respective devices. The announcement is receivable by any device on the local network segment. A request is received at the device for a detailed description of the service information in response to the announcement. A description of the service is sent from the communications device to the originator of the request in response to the request, and the service is established between the originator and the communication device and/or network entity in response to the sending of the description of the service
Abstract:
A server for a communication system is disclosed. The server is configured to receive group communication information comprising a group detail indicator. The group detail indicator provides information on at least an identity of a group and a type of the group. The server is further configured to store the group communication information, and to make the group communication information available to predefined entities.
Abstract:
The present invention relates to a session merging entity in a communication system IMS. The merging entity is handling communication of the first user; the communication includes a first session and a second session. The first session and the second session are merged into a single session towards the second user, if the same IMS communication service identifier has been indicated for the first session and the second session. The merging entity may also be located at the terminal device of the second user.
Abstract:
Methods and apparatus, including computer program products, are provided for emergency call support. In one aspect there is provided a method. The method may include a home subscriber server receiving a first message comprising a generated value representing a session transfer number. The session transfer number may relate to a transfer of an emergency session from a first network to a second network. The method may further comprise a home subscriber server updating a user profile with the generated value representing the session transfer number for the emergency session. The user profile may be stored in the home subscriber server. The method may further comprise a home subscriber server sending a second message comprising the generated value representing the session transfer number. Related apparatus, systems, methods, and articles are also described.
Abstract:
A method can comprise providing single voice radio call continuity using packet data network bi-casting, wherein the call continuity is provided during a handover of a user equipment from a real-time transport protocol voice to a circuit switched voice call In such a method, the real-time transport protocol voice can be carried m a long term evolution system and the circuit switched voice call can be carried in a second or third generation system The method can be performed by a serving network of the user equipment.
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:
The present application discloses a system of at least a network element and at least a terminal. The system constituents are configured to provide assistance by the terminal to the network element in terms of access domain selection for at least one of the media channel and the session control channel of an incoming call to the terminal. In this regard, the terminal acquires information about the capabilities of an access network in which the terminal is camping. Upon receiving, at the terminal, an invitation to participate in a call, the terminal analyzes the acquired information about the capabilities of the access network, and optionally or additionally of the IMS network. The terminal responds to the invitation, based on the result of the analyzing, with an indication that indicates a respective access domain to be used for at least one of the media channel and the session control channel of the incoming call.
Abstract:
There is proposed a method and corresponding apparatuses allowing a change from a packet switched communication domain to a circuit switched communication domain. When a user equipment as a connection terminating point receives a connection initialization message with a media flow, such as audio, which cannot be delivered by the packet switched access, it sends a specific response rejecting the connection via the packet switched access to an application server for service centralization and continuity. In the application server, it is checked whether several conditions are met in order to determine whether the communication connection comprising the media flow is allowed to be changed to the circuit switched domain. If yes, the communication connection is changed from the packet switched communication domain to the circuit switched communication domain.
Abstract:
In a service level interworking unit, a service center (SC) address or a set of SC addresses dedicated for the service level interworking is used whenever an instant message (IM) is interworked to a short message (SM). In other words, if a message is initially sent as an instant message (IM) by user equipment (UE) and is interworked to a short message (SM) by the interworking function, the interworked short message (SM) is sent to a dedicated service center (SC) address. For originating messages that are not interworked, different service center address or addresses are used. A terminating short message (SM) received at the interworking unit is interworked to an instant message (IM) and the interworked instant message (IM) is delivered to the user equipment (UE), if a service center address in the terminating short message (SM) is one of the dedicated service center addresses. If the a service center address in the terminating short message (SM) is not one of the dedicated service center addresses, the terminating short message (SM) is delivered to the user equipment (UE) without a service level interworking.
Abstract:
Aspects of the present invention relate to methods and entities involved in enabling and improving inter-domain handover. A PS based RAN such as eUTRAN can identify which potential handover to prepare and which handover to initiate, PS-PS or SR-VCC based on: (1) the UE's SR-VCC capabilities, (2) “SR-VCC indication” from the MME, (3) active VoIP bearer, and (4) target cell capabilities.
