Abstract: The invention relates to an elevator drive unit for managing a regenerative power of an elevator system. The elevator drive unit comprises: first terminals for connecting the elevator drive unit to the mains; second terminals for connecting the elevator drive unit to an elevator hoisting motor; a frequency converter for enabling a bidirectional transfer of power between the mains and the elevator hoisting motor; and a control unit. The control unit is configured to: obtain an indication representing a detection of a special operational situation of the elevator system, introduce a non-zero power limit specific to the detected special operational situation of the elevator system, and control the frequency converter to limit supply of the regenerative power from the elevator hoisting motor to the mains to the power limit. The invention relates also to an elevator system and a method for managing a regenerative power of an elevator system.

Abstract: An apparatus for providing advertising content to terminals communicating over a communications network is provided. The apparatus includes a processing element that communicates with network elements residing on the network or other networks to receive information regarding the terminals and their users. At least one of the terminals may be a mobile terminal. The processing element communicates an instruction to an advertising platform based on this information, and the advertising platform in turn selects and transmits advertising content to the respective terminals according to the instruction. Such content may include text messages, voice messages, picture messages, video clips, and more. In some cases, the processing element may determine a common characteristic of two or more terminals and their users based on the information received, and advertising content based on that common characteristic may be sent to the terminals. A method, system, and computer program product are also provided.

Abstract: 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 said 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 said support node to said user equipment. Said activate PDP context accept message acknowledges said 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.

Abstract: A technique for hiding network element names and addresses in communications between first and second networks includes providing a message generated by a network entity in the first network to be delivered to a target network entity in the second network, the messaging including first and second parts. The message generated by the network entity in the first network is routed to a contact point disposed between the first and second networks in accordance with the first part of the message and the message generated by the network entity in the first network is routed from the contact point to the target network entity in the second network in accordance with the second part of the message.

Abstract: The invention relates to a communication method and system wherein a network element of a roaming user is attachable to a visited first network and be served by a serving means of the home network. When the network element of the roaming user is registering or initiating a connection to a called network element of the visited network, a network element of the visited network, such as proxy means, either adds information on the called network element or on a service element of the visited network when sending a message to the home network. The message is preferably sent as a protocol message, in particular a message of the Session Initiation Protocol.

Abstract: The invention relates to a method and system for establishing an emergency session in a communication system which includes at least one user equipment and one or more network entities involved in establishing an emergency session. When the user equipment initiates a session by sending a message to a network entity indicating an identifier, e.g. the call number or logical name of a called entity, one of said network entities analyses the received identifier. When detecting that the session to be initiated is an emergency session, an information is returned to the user equipment for informing the latter that the initiated session is an emergency session. The user equipment thereupon initiates the execution of an emergency session. Thus, even when the user equipment is unable to detect, by itself, that the intended session is an emergency session, the network will inform the user equipment on the emergency session for ensuring appropriate handling thereof.

Abstract: The invention proposes a network system comprising a first network element (2) and at least a second network element (3), the second network element being adapted to operate in at least two different modes, wherein the first network element (2) is adapted to send a message to the second network element, and the second network element (3) is adapted to set the mode in response to information included in the message and indicating whether a particular procedure is to be performed and/or has been performed. Thus, the second network element sets its mode dependent on whether a procedure like processing of a location request has to be performed or has not to be performed, or, whether a procedure has been performed or not. The network elements can be Call State Control Functions (CSCF).

Abstract: Systems, apparatuses and methods for providing the identity of communication device users who initiate communications from data networks such as the Internet and that are targeted for users in circuit-switched domains. A calling party identifier is received from a calling terminal initiating a voice call. A circuit-switched (CS) domain identifier is associated with the calling party identifier. The association of CS domain identifier and calling party identifier is provided to a targeted terminal, which may store the associated information. The voice call and the CS domain identifier associated with the calling party identifier are thereafter directed from the calling terminal to the targeted terminal. The targeted terminal may then identify the calling party using the CS domain identifier to identify the associated calling party identifier.

Abstract: The present solution relates to a telecommunications system where information is maintained of communication groups available to a user terminal (UE). A communication server (PoC server) of the system is able to receive a request message (3-1) sent by the user terminal (UE), the request message (3-1) comprising an indication of the communication group the user wishes to speak to. If the request can be accepted, the communication server (PoC server) transmits a floor granted message (3-2) to the user terminal (UE). According to the present solution the communication group requested by the user is set (3-3) as the priority communication group for said user at least for a predetermined time period.
