Problems solved by technology

[0007] The present invention provides a method and device for transmitting SIB7 through RIM messages, which are used to solve the problem that the update of SIB7 information between RNC and E-UTRAN in the prior art is consistent with the update in the RNC cell, resulting in a large number of problems between RNC and E-UTRAN. RIM message, causing the problem of rising processing load in RNC, E-UTRAN and core network

Embodiment 1

[0038] The embodiment of the present invention provides a method for transmitting SIB7 through RIM message, which is applied in RNC, such as figure 1 shown, including the following steps:

[0039] Step S101, according to the public measurement report of the cell, obtain the reported uplink noise floor of the cell;

[0040]Step S102, detecting whether the absolute value of the difference between the reported uplink noise floor of the cell and the uplink noise floor in the last updated SIB7 is continuously greater than the set threshold and the duration meets the specified threshold;

[0041] Step S103, when the detection result is yes, update the uplink noise floor in SIB7 by using the acquired latest uplink noise floor of the cell, and transmit the updated SIB7 to E-UTRAN through RIM message.

[0042] It should be noted that the above-mentioned processing procedure is for one cell, and the above-mentioned same processing manner can be adopted for different cells.

[0043] It...

Embodiment 2

[0054] An embodiment of the present invention provides a method for transmitting an SIB7 through a RIM message, which discloses more technical details to describe the method in Embodiment 1 in more detail. Specifically, in the method of this embodiment, a judgment threshold and a time lag threshold for the UL interference difference updated by the SIB7 of the RIM are newly added. Within the time range specified by the time lag threshold, the absolute value of the difference between the latest UL interference in all cell common measurement reports of a cell and the UL interference in the last updated SIB7 always meets this new threshold, and then triggers RIM news, to bring this latest ULinterference to E-UTRAN in SIB7.

[0055] Specifically, such as figure 2 As shown, the method described in this embodiment includes the following steps:

[0056] Step S201, start;

[0057] Step S202, receiving the public measurement report of the cell;

[0058] Step S203, judging whether t...

Embodiment 3

[0066] An embodiment of the present invention provides a method for transmitting an SIB7 through a RIM message, which discloses more technical details to describe the method in Embodiment 1 in more detail. Specifically, in the method of this embodiment, the time lag threshold in Embodiment 2 is replaced by the number of times the difference threshold is met continuously. That is to say, the absolute value of the difference between the latest UL interference in the cell public measurement report of a cell and the UL interference in the last updated SIB7 satisfies the newly added difference threshold, and after several consecutive public measurement reports are satisfied, The RIM message is triggered to bring the latest UL interference to E-UTRAN in SIB7.

[0067] Specifically, such as image 3 As shown, the method described in this embodiment includes the following steps:

[0068] Step S301, start;

[0069] Step S302, receiving the public measurement report of the cell;

Abstract

The invention discloses a method and a device of transmitting SIB7 by an RIM message. The method comprises steps that an uplink background noise of a reported cell is acquired according to the public measurement report of the cell; whether an absolute value of a difference value between the uplink background noise of the reported cell and the uplink background noise of the lately updated SIB7 is constantly greater than a preset threshold value and whether a duration length satisfies a predetermined threshold are detected; when detection results are yes, the uplink background noise of the SIB7 is updated by using the acquired latest uplink background noise of the cell, and the updated SIB7 is transmitted to an E-UTRAN by the RIM message. Message flow between an RNC, the E-UTRAN, and a core network is reduced, and greatly rising of processing loads of network elements is prevented.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting SIB7 (system information block 7) through RIM (RAN Information Management, radio access network information management) messages. Background technique [0002] RIM functions are UTRAN (UMTS Terrestrial Radio Access Network, UMTS Terrestrial Radio Access Network), E-UTRAN (Evolved UTRAN, Evolved UTRAN) and GERAN (GSM / EDGE Radio Access Network, Global System for Mobile Communications / Enhanced Data Rate GSM Evolution A function of exchanging information between technical wireless access networks) through the core network. [0003] With the widespread commercial use of E-UTRAN, the RIM function is more and more widely used among UTRAN, E-UTRAN and GERAN. In order to improve the speed of UE accessing UTRAN from the E-UTRAN network, the UTRA SI (UTRA System Information) function of RIM can transmit the SI information of the UTRAN cel...
