摘要:
A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updated key is encrypted using the broadcast key and provided periodically to a user. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key. One embodiment provides link layer content encryption. Another embodiment provides end-to-end encryption.

The invention relates to the technical field of physiotherapy apparatuses, and discloses a method and system for controlling physiotherapy apparatuses. The method is applied to physiotherapy apparatuses. The physiotherapy apparatuses include a remote controller, a host and electrode sheets. The remote controller is wirelessly connected to the host computer. The remote controller is used to transmit signals to remotely control the host computer. The host computer and the electrode sheets are connected through connecting pieces, the connecting pieces are metal snap buttons, and the host computer is used to receive signals transmitted by the remote controller and generate pulse signals to be transmitted to the electrode sheets. The present invention connects a plurality of hosts through a remote controller, realizes wireless control of multiple hosts by a remote controller, and can use different massage modes for different parts to meet the needs of users for different massage modes. It also improves the reliability of product signal transmission by selecting a specific communication channel, and multiple hosts can receive control signals from the control terminal in a timely and accurate manner, reducing the interference of other signals on the equipment.
摘要:
Techniques are provided for conserving network resources in a network that initiates data services by communicating push data to a dormant terminal. Selected network resources associated with the dormant terminal are released, and maintained information for reaching the dormant terminal is updated when the point of network attachment of the dormant terminal changes.

A method and apparatus for dynamic home address assignment by a home agent in multiple network interworking. The invention provides a method and apparatus send a key authorization request from a mobile station to a network device, the request indicating that the mobile station wishes to use a foreign agent care-of address to continue to receive data. The network device assigns a temporary address to the mobile station and creates a security policy database for the mobile station. The mobile station receives agent advertisements from foreign agents that may be able to provide service. The mobile station registers with a foreign agent. The network device then modifies the security policy database to reflect the information of the foreign agent. The Home Agent then assigns a home address to the mobile station and the network device updates the security policy database to include only the mobile device's home address as a selector.

In a packet data communication system in which communicating nodes assume different modes of communications, and packet data are sent through a monitoring intermediary for data traffic control, the different modes of communications are directly sent to the monitoring intermediary so as to allow the monitoring intermediary to straightforwardly set up data filters for carrying out the data control and monitoring functions.

A method and apparatus for providing policy control in a wireless communication system. A mobile station generates a resource request for a communication service, where the resource request includes an identifier uniquely identifying a type of communication service. A packet data serving node receives the resource request for the communication service and selects a policy control entity to process the resource request. The selection by the packet data serving node is based at least on the identifier. The selected policy control entity performs policy control on the resource request.
