Preset resource active method in mobile communication system

Abstract

This invention relates to a process method for preserved resources in the mobile communication system, which applies different technologies to judge if the preserved resource activated parameters of SRNC to NodeB are effective to guarantee prompt and reliable communication, for example, the synchronous poll of the SRNC to the preserved resource periodic transmission channels is changed to that the NodeB responds the synchronous control frame of the transmiossion channels only after the activation and the parameter are valid to provide the criterion in the activation process.

Description

technical field [0001] The invention relates to a method for processing reserved resources in a mobile communication system, in particular to a method for activating reserved resources in a third-generation mobile communication system. Background technique [0002] Today, with the rapid development of personal communication, the market demand has greatly promoted the progress of mobile communication technology. Especially in the third generation mobile communication system (3rd Generation, referred to as "3G"), each standard system has its own enhancement technology for improving system performance. Among them, resource reservation is an enhanced technology, which saves connection time overhead by reserving wireless link resources during communication connection for reactivation for communication. In the 3G communication system of Wideband Code Division Multiple Access (WCDMA for short) or Time Division Synchronous Code Division Multiple Access (TD-SCDMA for short), accordi...

Problems solved by technology

[0017] In practical application, the above scheme has the following problems: Since the SRNC cannot know exactly whether the IE takes effect in the NodeB and whether the wireless link parameters in the NodeB have been modified, it must wait for a long enough time to ensure that the NodeB modification is completed during activation, so that increase the activation delay

However, the fundamental problem of this mechanism is that it is impossible to know that the reserved resources are available, and there is always a hidden danger of communication security.

In practical applications, in order to speed up the activation process of reserved resources, SRNC hopes to deliver data during the process of modifying NodeB parameters. However, since the completion of the modification of the activation resource parameters cannot be guaranteed, SRNC often delays the data in the new node through anticipation. When the link is issued, this method is not only inaccurate but also very time-consuming, and cannot make full use of the advantages of shortening the link establishment time after the activation resource has been established. In serious cases, it may cause a signaling delay in the activation link method. It is greater than the signaling delay of selecting an additional newly established link, which completely deviates from the original intention of the reserved resource activation mechanism

[0018] The main reason for this situation is that the existing technical solution does not provide a mechanism for the SRNC to ensure that the IE takes effect in the NodeB and the wireless link parameters of the NodeB are modified. There are potential safety and reliability risks in the communication, and the SRNC predicts and waits for the following This method of ensuring that the wireless link is valid will bring additional processing delay, reduce system efficiency, and increase processing delay
