Embodiment Construction

[0013] (Structure of the mobile communication system according to the first embodiment of the present invention)

[0014] Below, refer to Figure 1 to Figure 6 The configuration of the mobile communication system according to the first embodiment of the present invention will be described.

[0015] Such as figure 1 As shown, the mobile communication system according to this embodiment includes a radio network controller RNC, a radio base station BTS, and a plurality of mobile stations UE#1 and UE#2.

[0016] In the mobile communication system according to the present embodiment, EUL (Enhanced Uplink: Enhanced Uplink) communication of the "Time & Rate" (time and speed) method described later can be performed. Specifically, in the mobile communication system according to this embodiment, the mobile station UE, according to the E-DPDCH (E-DCH Dedicated Physical Data Channel, used for high-speed uplink communication) corresponding to the received AG (Absolute Grant, scheduling g...

Abstract

A wireless base station (BTS) comprises: an upper limiting value management section (22) that determines and manages a common upper limiting value in respect of all the mobile stations (UE), based on the bandwidth that is usable for transmission of uplink data in a wired zone (Iub) with respect to a radio network controller (RNC), and a scheduling section (23) that determines the AG to be transmitted in respect of the mobile stations (UE) that are the subject of scheduling of EUL communication in such a way as not to exceed the upper limiting value. The upper limiting value management section (22) is constituted in such a way as to lower the upper limiting value if a congestion signal in the wired zone (Iub) is received a prescribed number of times in a first prescribed period.

Description

technical field [0001] The present invention relates to radio base stations. Background technique [0002] In recent years, it has been studied to install a small radio base station (hereinafter referred to as a femto radio base station) BTS called a femto cell, which can form a small communication area, in a place such as a user's house. [0003] However, it has been studied that such a femto wireless base station BTS is connected to a best-effort line (commonly used broadband line) installed in the user's house. Influenced by the traffic caused by other equipment, compared with the case of connecting to a bandwidth-guaranteed dedicated line, uplink data loss may occur in the wired section (Iub) between the radio network controller RNC and the radio base station BTS The problem that the possibility of (packet loss) becomes high. Contents of the invention [0004] The first feature of the present invention is a wireless base station used in a mobile communication system,...
