Problems solved by technology

[0019] In the scenario where there is no block error on the air interface, the link conversion process in synchronous reconfiguration does not need to be very long and the connection can be completed smoothly. However, the network side reserves a relatively long conversion time to prevent link drop when the block error is high. , resulting in a very long connection delay for link switching in the scenario where there is no block error on the air interface

[0043] Embodiment 1: In this solution, when the reconfiguration takes effect, UTRAN reserves two sets of necessary resources of the old and new links, and transmits and receives simultaneously through the old and new links to ensure that the UE can receive all the messages and perform subsequent message interactions.

[0044] figure 2 It is an information interaction flow chart of the first embodiment of the present invention. see figure 2 , the first embodiment mainly includes:

[0045] In step 201, the RNC and NodeB complete the establishment of the link, and the bearer is DCH or HSDPA. This configuration is called an old link. After the RNC receives the RAB assignment, the link after reconfiguration is called a new link. Here, the RNC allocates resources so that the resources occupied by the old and new links before and after the reconfiguration takes effect between the RNC and the NodeB are separated, including: channel code, FP ID, and Alcap resources.

Abstract

The invention discloses a management and conversion method of old and new link resources in a communication system, which is characterized in that the conversion time is set for the network side and the UE respectively, and the conversion time set for the UE is shorter than the conversion time set for the network side; After receiving all the link conversion messages, the old and new links are converted according to the conversion time set for it; after the network side configures the new link, the old and new links are kept in communication with the UE at the same time until the conversion on the network side After the time is up, switch between the old link and the old link, and switch the old link to the new link. The invention can ensure that the connection time delay of link switching can be improved while the link is not lost.

Description

technical field [0001] The invention relates to link connection conversion technology of a communication system, in particular to a link resource management and conversion method for shortening connection time delay in a communication system. Background technique [0002] Connection delay is an important issue in wideband code division multiple access (WCDMA) systems. Too long connection delay will directly affect the subjective experience of users and affect the loyalty of users to the WCDMA operating network. The link establishment in the connection process is divided into synchronous establishment and asynchronous establishment. Synchronous establishment is during the establishment process, the radio network controller (RNC) notifies the base station (NodeB) and the user terminal (UE) to switch from the old link to the new link at a specified switching time (CFN). Asynchronous establishment means that RNC establishes links for NodeB and UE respectively, but it does not g...
