20100262654 | CALL CONTROL METHOD, DEVICE, AND SYSTEM - A method, a device, and a system for realizing unified communication in the field of communication are provided, so as to solve the problems in the conventional art that a client can only initiate a call to a terminal instead of controlling the subsequent call and that no call association exists between the client and the terminal. A call control method of a softswitch equipment includes: sending a call identification and call state information to an application server, so that the application server sends the call identification and the call state information of the call to a client bound to a terminal; receiving a control request including the call identification and a control instruction and sent by the application server; and controlling the call corresponding to the call identification according to the control instruction in the control request. The present invention is applicable to the unified communication mode. | 10-14-2010 |

20090238163 | METHOD AND SYSTEM FOR DETERMINING AND OPTIMIZING THROUGHPUT OF SHORT RANGE WIRELESS NETWORK - Methods and systems for determining and optimizing a throughput of a short range wireless network are provided. The method mainly includes acquiring respective time parameters in a contention access period based on information transmission characteristics of the short range wireless network; and computing and optimizing the throughput of the short range wireless network based on the respective time parameters. These time parameters are determined based on a non-persistent Carrier Sense Multiple Access CSMA mechanism. Therefore, the present invention employs a non-persistent CSMA mechanism to analyze the CAP of a short range wireless network and thus simplifies complexity in determining the network throughput and the analysis process of network optimization. As such, accurate throughput parameters of the standard network of the short range wireless network may be obtained, the network performance may be optimized and the performance of the short range wireless network is improved. | 09-24-2009 |
