Patent number: 8660009Abstract: A cellular radio communications network includes a core network with a core network node coupled to a radio access network (RAN) associated with a first radio access technology for communicating with mobile radio terminals. The RAN includes multiple RAN nodes. Each mobile radio terminal has an associated access class for accessing service from the cellular radio communications network. The core network node detects an overload condition and sends an overload message to the RAN nodes that includes information for reducing the overload condition. Each of the RAN nodes receives the overload message and determines whether an access class restriction should be implemented to reduce the number of mobile radio terminals permitted to access the cellular radio communications network. If so, the RAN node determines one or more access classes of mobile radio terminals to be restricted based on the information in the overload message.Type: GrantFiled: January 30, 2008Date of Patent: February 25, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Anders Dahlén

Patent number: 8660609Abstract: There is disclosed a manner of controlling traffic by admission control in a communication network such as one operable according to GSM standards. When a call setup request is received from an MS, the BSC forwards the request to an MSC, which selects a MGw that is accessible to the BSC via an IP backbone. When notified of the MGw selection, the BSC runs an algorithm to assess the transmission quality of the IP backbone toward the MGw. The BSC then determines whether to reject the call setup request depending on whether the quality level is acceptable as determined by the algorithm. If the call setup proceeds, the MGw may run a similar algorithm to assess the quality of the IP backbone toward the BSC. The BSC and MGw may also check their own bandwidth limitations prior to running their respective algorithms.Type: GrantFiled: August 1, 2008Date of Patent: February 25, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventor: Jens Poscher

Patent number: 8660082Abstract: The invention relates to a method and arrangement for transmitting and receiving control information in a radio-access network. A network node transmits first control information in a first part and second control information in a second part of a time-frequency region that is transmitted after a control region in a subframe. The second part is located later in the subframe than the first part. The second control information may be less time-critical than the first control information. An intermediate node receives and decodes the first control information at the end of the first part. When the first control information indicates that the subframe comprises data payload to the intermediate node, the intermediate node receives and decodes the data payload. The intermediate node receives second control information at the end of the second part.Type: GrantFiled: June 22, 2010Date of Patent: February 25, 2014Assignee: Telefonaktiebolaget L M EricssonInventor: Stefan Parkvall

Patent number: 8661243Abstract: A method apparatus for storing and forwarding media data in a communication network. An intermediate node disposed between a media data source node and a client node receives encrypted media data packets from the media data source node. The intermediate node stores the received media data packets in a memory for later sending to the client node, and adjusts fields in the original header of each stored media data packet to create modified media data packets having a modified header, and sends adjustment information to the client node. The adjustment information allows the client node to recreate the original headers from the modified headers, before decrypting the encrypted media packets with keying materials already sent between the media data source node and the client node. The modified media data packets are then sent to the client node for decryption. This allows the intermediate node to “store and forward” SRTP data without being able to access the encrypted data content.Type: GrantFiled: June 16, 2008Date of Patent: February 25, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Rolf Blom, Karl Norrman
