Mobile telecommunication new services are based on data networks specially Internet. These services include http, telnet, ftp, SMTP, etc. In addition we recognize that a mobile network is a multi-user network. Layer 3 of UMTS system provides call admission control and radio resource management. QoS can be guaranteed based on these modules. In order to have a suitable distribution of resources in a multi-user data network we need to use a queue. Queue control in the system has an important role in quality enhancement of the network. 3GPP has proposed an algorithm to control this queue. In this paper we have added a new property to this algorithm that makes blocking rate very low, however it increases the delay by a negligible amount. This property is based on the retransmission of the blocked packets in predefined times.
