Embodiment 1

[0038] The failure signaling of the reconfiguration process is realized by extending the radio link failure indication message RADIO LINKFAILURE INDICATION, and the reason value of "error while waiting for reconfiguration submission" is added to the information element IE of the failure reason of the message, as shown in Table 1; the failure reason is based on Invented a new reason indicator value, used for receiving the synchronous radio link reconfiguration request side network element in the process of waiting for the radio link reconfiguration signaling (RADIO LINK RECONFIGURATION COMMIT, or RADIO LINK RECONFIGURATION CANCEL), if an internal error occurs or a failure, or when a timeout occurs, instruct the corresponding network element on the other side to cancel the reconfiguration.

[0039] The modifications involving the Iub port 25.433 protocol message / Iur port 25.423 protocol message are shown in Table 1, where bold italics, underlined parts, and blackened fonts are ne...

Embodiment 2

[0055] The reconfiguration process failure signaling is implemented by adding a new reconfiguration failure notification message WAITRECONFIG COMMIT FAIL NOTIFY. As shown in Table 2, the side network element used to receive the synchronous wireless link reconfiguration request waits for the wireless link reconfiguration request. In the process of signaling (RADIO LINK RECONFIGURATION COMMIT or RADIO LINK RECONFIGURATION CANCEL), if an internal error or failure occurs, or a waiting timeout occurs, instruct the corresponding network element on the other side to cancel the reconfiguration process. The bold italics, underlined parts and bold fonts in Table 2 are new parts.

Abstract

The invention discloses a method for performing synchronous reconfiguration between wireless network elements and a corresponding device. The method comprises the following steps: in the processes of preparing the synchronous reconfiguration and submitting the synchronous reconfiguration of a wireless link, sending a wireless link synchronous reconfiguration request to a second network element by a first network element; when the second network element judges that the second network element cannot receive a wireless link reconfiguration signaling transmitted by the first network element, transmitting a reconfiguration process failure signaling to the first network element; and after the first network element receives the reconfiguration process failure signaling, performing a reconfiguration cancelling processing, so resource configuration rolls back before the reconfiguration. In the invention, signaling interaction vulnerability existing in an original synchronous reconfiguration process is overcome, so that the resource configurations of corresponding network elements on both sides are kept accordant. Therefore, user service quality is greatly improved and excellent user experience is provided.

Description

technical field [0001] The invention relates to an information exchange method between network elements in the field of mobile communication, in particular to a method for synchronous reconfiguration between network elements in a Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system and a corresponding device. Background technique [0002] In a WCDMA system, usually when one or more wireless links of the Iur port or the Iub port need to be reconfigured synchronously, the source radio network controller (SRNC, Source Radio Network Controller) sends a report to the drift radio network controller (DRNC, Drift Radio Network Controller), or the radio network controller RNC sends a synchronous radio link reconfiguration request (RADIO LINKRECONFIGURATION PREPARE) to Node B (NodeB); DRNC returns synchronous radio link reconfiguration to SRNC or NodeB after processing and returns to RNC Response (RADIO LINKRECONFIGURATION READY); After the SRN...
