Although I do not like to follow the follow, but there are some areas of Ajax is more useful. Some time ago did a EASYJF open source team of online conferencing system, used AJAX technology, the following design ideas issued to share with you. 　　 the function of sy

networks with packet switching, such as GPRS and third-generation networks, WAP gateway servers can be directly connected with IP, which is not discussed here. However, for non-IP networks, such as GSM circuit Exchange data (CSD) network, it is possible to adopt a number of different forms of connection.

Acoustic echo is the sound of the Speaker's voice is picked up by the

GPRS, the concept of service level is increased, and the QoS of group domain is improved and the bandwidth is increased. From the system point of view, the system still uses the grouping domain and the circuit domain respectively load and the processing way, respectively accesses the PSTN and the public data network. From a general standpoint, R99 more mature, more suitable for the need to immediately deploy the network of new operators, but also fo
