Embodiment Construction

[0033] 34 The base station 10 and the radio network controller 20 of the UMTS wireless communication network are in figure 1 It is represented by a vertical line and provides packet data transmission through the Transmission Control Protocol (TCP).

[0034] Data transmission between the radio network controller 20 and the base station 10 is performed according to the High Speed ​​Downlink Packet Access Mode (HSDPA), wherein TCP packet data passes through MAC-d contained in HS-DSCH data frames DF_1, DF_2... Protocol data units (PDUs) are delivered from the radio network controller 20 to the base station 10 .

[0035] from figure 1As can be seen in , the base station 10 automatically issues the first capacity allocation message CAM_1 to the radio network controller 20 . In this specification, "automatically" means that the base station 10 does not wait for any incoming control message or timing or similar to trigger the first capacity allocation message CAM of the present inve...

Abstract

The invention relates to a method of operating a base station of a wireless communication network, wherein data is transferred between the base station (10) and a radio network controller (20). The method of the present invention is characterized in that the base station (10) automatically issues a first capacity allocation message (CAM_1) to the radio network controller (20), which message includes capacity information of the basic data transmission capacity currently supported by the base station (10) . The invention also relates to a base station (10) and a radio network controller (20) of a wireless communication network.

Description

technical field [0001] The invention relates to a method of operating a base station of a wireless communication network, wherein data is transferred between the base station and a radio network controller. [0002] The invention also relates to a base station of a wireless communication network, wherein data is transferred between said base station and a radio network controller. The invention also relates to a radio network controller of a wireless communication network. Background technique [0003] Existing wireless communication networks, such as the Universal Mobile Telecommunications System (UTMS), etc., provide packet data transmission by using the Transmission Control Protocol (TCP). The slow start mechanism of TCP, for example, in the document "TCP slow start, congestion avoidance, fast retransmission and fast recovery algorithm", contained in IETF RFC2001 (Internet Engineering Task Force, Request for Comments, refer to http: / / www.ietf.org) and "TCP Congestion Co...
