Problems solved by technology

In this scenario, the RNC cannot detect changes in the physical link status and available bandwidth at the base station through the IMA protocol or the link state machine in MLPPP
In addition, in the IUB full Internet Protocol (IP, Internet Protocol) transmission scenario, the base station usually negotiates the working mode and rate of the Ethernet with the site-side switch. At this time, the RNC cannot directly perceive the actual rate of the Ethernet port of the base station Negotiation result
[0006] It can be seen from the above description that in the above scenario, if the RNC continues to perform CAC and flow control according to the pre-configured bandwidth threshold, when the actual physical bandwidth threshold of the base station is smaller than the configured bandwidth threshold, congestion and loss may occur.

Embodiment Construction

[0040] The basic idea of ​​the present invention is: after the base station establishes a connection with the RNC, the base station reports the bandwidth threshold of its current physical port to the RNC.

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] The method for the RNC of the present invention to obtain the base station transmission bandwidth threshold, such as figure 1 shown, including the following steps:

[0043] Step 101: After the base station establishes a connection with the RNC, the base station reports the bandwidth threshold of its current physical port to the RNC;

[0044] Here, the establishment of the connection between the base station and the RNC may specifically be: the establishment of an IUB interface signaling connection between the base station and the RNC, that is: establishment of an NBAP protocol signaling connection;

[0045] The base station ...

Abstract

The invention discloses a method for a radio network controller (RNC) to obtain the transmission bandwidth threshold of a base station. The method includes: after the base station establishes a connection with the RNC, the base station reports the bandwidth threshold of its current physical port to the RNC. The invention also discloses a system for the RNC to obtain the transmission bandwidth threshold of the base station. By adopting the method and the system of the present invention, the RNC can effectively detect the actual bandwidth threshold of the base station, so that the RNC can update the IUB interface downlink currently saved by itself in time. Call Admission Control (CAC) and the bandwidth threshold of flow control can effectively implement CAC and flow control to ensure the quality of service and avoid congestion and packet loss.

Description

technical field [0001] The present invention relates to the third-generation mobile communication (3G, 3rd-Generation) technology, in particular to a method and system for a radio network controller (RNC, Radio Network Controller) to obtain a base station transmission bandwidth threshold. Background technique [0002] In the 3G network, in order to ensure the quality of service (QoS, Quality of Service), in the establishment, modification, and release process of the service, it is necessary to perform call admission control (CAC, Call Admission Control); for the accessed packet service, it is also necessary to perform flow control according to the occupancy of the transmission bandwidth resource of the IUB interface. When implementing CAC, it is necessary to reserve sufficient transmission bandwidth resources for the admission of each service. When performing flow control, it is necessary to ensure that the actual amount of data entering or leaving network elements does not ...
