Abstract: A floor joist system (9) comprises a flat sheet metal structural web member (10) for interconnecting a pair of parallel spaced apart wood chord members (11), said web member (10) being V-shaped, comprising first and second legs (12, 13) integrally joined at one of their respective ends, a plurality of teeth struck from said one end of each leg (12, 13) and extending from one face, constituting the inside face, of the web member (10), said teeth being adapted to be driven into one of the chord members (11), and a plurality of teeth struck from the other end of each leg and extending from the inside face of the web member (10), said teeth being adapted to be driven into the other of said chord members (11). The system further comprises a bracket (1) for holding a suspended ceiling.

Abstract: A bracket (1) for holding a suspended ceiling has a first end (2) for anchoring the bracket (1) to a beam or the like of a building structure and a second end (3) to which a mounting profile is attachable on which a building panel is mountable. The bracket (1) has a rectangular and flat part (4) that in use is horizontally arranged between the first and second ends (2, 3). The length (L) of the flat part (4) between the first and second ends (2, 3) is at least 1.5 times as long as the width (W) of the flat part (4).

Abstract: Systems and methods are provided for generating announcement information at a communication node. The method includes: generating a first announcement information associated with a first user; generating a second announcement information associated with a second user; and transmitting the first and second announcement information to a telephony application server, wherein the first announcement information and the second announcement information include at least one different element of data, further wherein both the first and second announcement information are used to generate or select announcements which are transmitted to the first and second users during a call between the first and second users.

Abstract: A charging trigger function (CTF 40) in a communication network (30) advantageously uses pre-allocated usage units to authorize the use of a communication service by a user, when a pre-allocated usage unit is available with respect to the involved communication service and user. A pre-allocation function (PAF 42) provides the one or more pre-allocated usage units directly to the CTF (40) or indirectly via an online charging function (OCF 44). The pre-allocated usage units are determined, for example, according to predicted usage information, user account information, and configured rules. A usage prediction function (UPF 52) in the network (30) uses user-related information, such as historical usage data or other activity by the user, to generate the predicted usage information. Among its other advantages, authorizing the use of the communication service based on pre-allocated usage units obviates or reduces the need for usage authorization signaling going between the CTF and OCF.

Abstract: A method of providing location-related charging information to a charging system associated with an IP Multimedia Subsystem, IMS, network, where the location-related charging information relates to a session or session initiation or an event involving at least two users. The method comprises, at a Charging Trigger Function, CTF, within the IMS network, receiving a Session Initiation Protocol, SIP, message from each of said users, each message containing a SIP header identifying a location of the sending user. Location information of each user is added to a charging message sent from the CTF to said charging system, location information being, or being derived from, the content of the SIP header received from the user or being derived from that SIP header.

Abstract: A node for use in a telecommunication network. The apparatus comprises a service session handler for establishing and controlling service sessions on behalf of end users served by the telecommunications network, and a charging generation point for generating charging data for established sessions involving served users as originating users and for reporting that charging data to a network charging system. The apparatus further comprises a signalling message handler for receiving, in respect of a given service session between an originating and a terminating user, a signalling message sent by or on behalf of the terminating user, the signalling message containing cost apportionment data apportioning costs between the originating and terminating users, the signalling message handler being configured to pass that cost apportionment data to the charging generation point.

Abstract: A method is provided for online charging within an IP Multimedia Subsystem, IMS. A first credit control request message is received (S-A) at an IMS charging node (30) from an IMS service network node (20) over a service charging interface (22) provided between the IMS service node (20) and the IMS charging node (30).

Abstract: A method is provided for online charging within an IP Multi-media Subsystem, IMS. A first credit control request message is received (S-A) at an IMS charging node (30) from an IMS service network node (20) over a service charging interface (22) provided between the IMS service node (20) and the IMS charging node (30). In response to receipt of the first credit control message, it is determined (S-B) at the IMS charging node (30), with reference to one or more triggering conditions, that a replenishment of credit is to be offered for a user associated with the first credit control request message. Following such a determination, a credit replenishment service is initiated in the IMS service node (20) by sending (S-D) a replenishment request in a first credit control answer message over the service charging interface (22) from the IMS charging node (30) to the IMS service node (20), the first credit control answer message being in response to the first credit control request message.
