摘要:
A simplified evaluation of messages that control connection setup is made possible by a method for filtering (4) incoming messages (3) at a connection controlling element (5) of a telecommunications network (13, 14, 5) on the basis of predetermined filtering conditions (8). According to this method, the filtering (4) ensues by comparing (4) text elements (20 to 29) in a received (6) message (3) with text elements (20 to 29) in a document (8), which can be accessed (7) by the connection controlling element (5) and which contains the filtering conditions in the form of text elements (20 to 29), and by verifying (4) whether, inside the document (8), logical links (30 to 32) of filtering conditions (20 to 29) apply to the message (3), said logical links being specified in an internet page description method (XML).
摘要:
A method for handling service failures for in a communications network comprising a user equipment, a first network element and a serving network element, the method comprising the following steps. Receiving at the first network element a first message from the user equipment. Transmitting the first message from the first network element to the serving network element. Detecting at the first network element that the serving network element is out of service. Determining at the first network element the type of the first message, and in dependence on the type of the first message sending from the first network element to the user equipment an error message including an indication that the serving network element is out of service.

The present invention relates to hiding a device identifier (IMEI) in a communication system. Identifying a device is done by indicating an international mobile equipment identity (IMEI) as an instance identifier of the device of a user. Generating aglobally routable user agent uniform resource identifier (GRUU) for the user is done by encrypting the instance identifier so that the GRUU comprises an identity of the user and the encrypted instance identifier.
摘要:
The routing information is extracted from a received message at a border between a first network and a second network, and at least one invalid entry is added to first-network entries of the routing information which relate to a routing path of the message within the first network. The at least one invalid entry and the first-network entries are encrypted by using an own token at least for each of the first-network entries. As an alternative, a tokenized second-network entry extracted from the routing information and relating to the routing path of the message within the second network is decrypted, and its content is reversed. In both cases, the routing information is replaced by the processed routing information and the message is forwarded to the second network. This allows to preserve the order of routing entries and to hide the amount of switches that have been traversed in the home network.

A coating apparatus (10) includes a chamber (12) defining a cavity (16), a diffuser (20), a vacuum valve (26), a burst valve (28), and a vacuum pump (30). In use, the chamber (12) is heated before a batch of lenses (46) to be coated are placed within the cavity (16) together with a tablet (42) impregnated with a coating substance. Air is then pumped from the cavity (16) until the pressure has been lowered to between 1×10-3 to 1×10-1 mbar (absolute pressure). The source tablet (42) is then heated by heater (38) to release a coating substance in vapour form. The burst valve (28) is then opened intermittently to allow small bursts of air to flow into the cavity (16). The diffuser (20) imparts swirling movement to the air burst as it enters the cavity (16), so that the air swirls around within the cavity thereby causing the vapour of the coating substance to be evenly distributed within the cavity and condense evenly on the lenses (46).
摘要:
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.

摘要:
The present invention relates to a method and terminal device for handling a suspended network state, wherein the end of a suspended network state is detected and subscription to a state event package is initiated in response to the detected end of suspension. Based on information given in a response to the subscription, registrations of user identities are updated. Thereby, the registration state of the user and the user's identities can always be kept actual, even after a suspension of the network connection.
摘要:
A system and method for enforcing policies for session-mode messaging between two or more communication devices. A policy is imposed by a signaling-level session control element on a communication device to establish a bearer-level binding between the communication device and bearer-level relay. A state of the bearer-level binding is determined, which is provided to the signaling-level session control element. The signaling-level session control element allows or disallows the first communication device to engage in the session-mode messaging based on the state of the bearer-level binding.
摘要:
A method (and corresponding equipment) by which a UE device (10) begins compressing messages it transmits to an SIP outbound proxy server (12) as SIP signals, including: a step (22a) in which the UE device sends a request message (22a 32a 42a) to the SIP outbound proxy server (12); and a step (23 33 43) in which the UE device analyzes a response message (22b 32b 42b) received from the SIP outbound proxy server (12) in response to the request message (22a 32a 42a) to determine a compression parameter. The request message (22a) may be an options request message and the response message (22b) would then be e.g. a 200 OK message. Alternatively, the request message (32a) may be a register message, and the response message (32b) would then be e.g. a 401 (unauthorized) message. In another embodiment, the response message (42b) is any compressed message.
