| 20120071186 | METHOD AND APPARATUS FOR RANDOM ACCESS - A method and an apparatus for random access are provided. The method includes: receiving, by a User Equipment (UE), an access indication message including a UE identifier (ID) and a corresponding resource number (101); sending a Dedicated Physical Control Channel (DPCCH) preamble by using an uplink resource corresponding to the resource number and preset initial transmit power (102); and if it is determined that an acquisition indication is received, determining, by the UE, that an access succeeds (103). Therefore, the reliability of information transmission is ensured, the delay in an access process is reduced, and fast implementation of uplink search is ensured. | 03-22-2012 |
| 20090279705 | METHOD AND SYSTEM FOR DISTRIBUTING KEY OF MEDIA STREAM - A method and a system for distributing key of media stream are provided. The method comprises: determining, by a security management server, whether a domain to which the calling terminal belongs and a domain to which a called terminal belongs subscribe a key distribution protocol; generating a key based on encryption capability information obtained in a calling process, and distributing the generated key to the calling terminal and the called terminal, if the protocol has been subscribed; generating a key based on encryption capability information obtained in a calling process, and distributing the generated key to the terminal at the same side as the security management server, if the protocol has not been subscribed. By applying the disclosure, the key is generated by the security management server, so that complexity may be reduced for media stream key negotiation to facilitate promotion of media stream encryption service. | 11-12-2009 |
| 20090238107 | METHOD FOR BEARER CONTROL AND DELETION, DATA DISTRIBUTION, AND MODIFICATION - A method for bearer control, bearer deletion, data distribution, and multicast broadcast service MBS modification are described, which enables MBS data to be received successfully and MBS sessions to be managed effectively. According to the invention involved in a communication field, service distribution information for one MBS service is maintained within MBS upstream and downstream nodes, and the MBS service distribution information is composed of a list of downstream nodes corresponding to the respective nodes. A corresponding service bearer and data distribution relation of the MBS are established and maintained based on the service distribution information, and service data of the MBS is distributed based on the service bearer and the data distribution relation. The MBS distribution information is pre-configured and/or dynamically maintained, the establishment of the service bearer is pre-configured and/or dynamically maintained, and the data distribution relation is pre-configured, distributed by default, and/or dynamically maintained. | 09-24-2009 |
| 20090182922 | BACKPLANE AND COMMUNICATION APPARATUS - The present invention discloses a communication apparatus. The communication apparatus includes one or more board and a backplane. The board includes a connector and a function processing unit circuit connected to the connector. The backplane includes at least one group of board connectors. Each group of the board connectors includes two board connectors that receive signals from different boards. The board connector includes connection terminals connected to the connector on boards. The two board connectors are distributed up and down, and the connection terminals of the two board connectors are distributed symmetrically around a center. The foregoing communication apparatus and backplane are cost-efficient. | 07-16-2009 |
| 20080317465 | Method and System for Implementing Transport Service of Ngn - A method for implementing transport layer service of NGN, wherein the NGN includes a service layer and a transport layer, the method including: establishing an independent transport-layer control device in the control plane of the transport layer in the NGN network; establishing a transport connection in the user plane of the transport layer under the control of the transport-layer control device; bearing the NGN service through the transport connection. The present invention also discloses a system for implementing transport layer service of NGN. According to the present invention, the network design of NGN may be simplified, the cost of the transport layer network may be reduced, and a strict QoS guarantee for NGN services may be provided. | 12-25-2008 |
