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 obtaining a base station transmission bandwidth threshold by an RNC (Radio Network Controller). The method comprises the step of reporting a current bandwidth threshold of a physical port of a base station to the PNC by the base station after the connection between the base station and the RNC is established. The invention simultaneously discloses a system for obtaining the base station transmission bandwidth threshold by the RNC. By adopting the method and the system, disclosed by the invention, the actual bandwidth threshold of the base station can be effectively detected by the RNC, thus the bandwidth threshold, which is currently preserved, of downlink CAC (Call Admission Control) and downlink flow control of an IUB interface of the RNC can be timely updated by the RNC, thus the CAC and the flow control can be effectively implemented, the service quality can be ensured, and the congestion and the packet loss can be avoided.

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 resources 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...
