    摘要： The invention relates to a method carried out by a service control entity to set up a communication path for exchange of service control messages with a service application entity (200) in a mobile communications network for controlling an application of a service, by the service application entity (200), to a media data flow, the media data flow being established between the service control entity (100, 300) and a remote end. A first message is transmitted on a service control channel, the first message comprising as a destination address an address of the remote end, wherein offer data is added to the transmitted first message, the offer data including an indicator indicating that the service control entity is configured to support a communication path on a media data plane of the media data flow based on Real Time Transport Control Protocol, RTCP, service control messages. A second message is received on the service control channel, wherein the second message comprises acceptance data in response to the offer data, the acceptance data comprising a receiver address at which the service application entity (200) is configured to receive RTCP service control messages. The receiver address is stored at which the service application entity (200) is configured to receive RTCP service control messages in order to set up the communication path between the service control entity and the service application entity.

    摘要： Encryption/authentication circuitry includes an encryption portion having a first number of encryption lanes, each encryption lane including a plurality of encryption stages, and keyspace circuitry including a plurality of key lanes corresponding to a predetermined maximum number of channels. Each key lane has key storage stages corresponding to the encryption stages, and includes key memories for the predetermined maximum number of channels. Key channel selection circuitry for each stage selects a key from among the key memories at that stage. An authentication portion includes a second number of authentication lanes, hash key storage for the predetermined maximum number of channels, partial hash state storage for the predetermined number of channels, and hash channel selection circuitry. Based on the channel being processed, the hash selection circuitry selects, in each respective lane, respective hash key data from the hash key storage and respective partial hash state data from the partial hash state storage.

    摘要： Embodiments of the present invention provide a method for detecting a network transmission status, and a related device. The method for detecting a network transmission status may include: measuring and calculating, by a first communications device, a transmission status characterization parameter used to indicate a status of network transmission between the first communications device and a second communications device; and if the transmission status characterization parameter meets a preset condition, sending, by the first communications device, a Real-Time Transport Protocol packet to the second communications device. Technical solutions provided in the embodiments of the present invention facilitate improving of estimation precision of available network bandwidth on a transmit end, and further improve bandwidth utilization and reduce phenomena such as a delay and an intermittent stop, thereby improving user experience.
