Problems solved by technology

[0005] In view of this, the technical problem to be solved by the present invention is to provide a Iub port data transmission control method and device to solve the problem that the Node B cannot send the corresponding MAC-d PDU through the UU port because the single MAC-d PDU issued by the RNC is too large. The problem of terminal data, improve the throughput of the system

Embodiment Construction

[0053] Hereinafter, the implementation of the Iub port data transmission method and device of the embodiment of the present invention will be described in detail in conjunction with the accompanying drawings.

[0054] In the following embodiments of the present invention, the data requested by the terminal issued by the RNC through the Iub port is called the Iub port data transmission of the terminal; the data requested by the Node B issued by the terminal through the UU port is called the UU port data transmission of the terminal .

[0055] figure 1 It is a schematic flow chart of a method for transmitting Iub port data according to an embodiment of the present invention, such as figure 1 shown, including:

[0056] Step 101: When determining the Iub port data transmission of the terminal, judge whether the SID of the MAC-d PDU in the previous Iub port data transmission of the terminal has the maximum value of SID, and judge that the previous UU port data transmission result...

Abstract

The invention discloses an Iub port data transmission method and a device thereof. The method comprises the following steps: while Iub port data transmission at a terminal is determined, judging whether an index SID of an MAC-d protocol data unit (PDU) in Iub port data transmission at the previous terminal shows a maximum value, and judging that the result of the previous UU port transmission at the terminal is ACK or NACK; when the maximum value of the SID is not shown and the result of the previous UU port transmission is ACK, determining the SID of MAC-d PDU in the current Iub port data transmission at the terminal according to the corrected correction step length and the smooth window length and the SID of the MAC-d PDU of the previous Iub port data transmission at the terminal; otherwise, determining the SID of the MAC-d PDU in the current Iub port data transmission at the terminal according to the correction step length and the smooth window length and the SID of the MAC-d PDU of the previous Iub port data transmission at the terminal; and finally establishing the MAC-d PDU according to the determined SID of the MAC-d PDU, and then sending the MAC-d PDU to Node B through an Iub port. The method and the device can improve the throughput of a system.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method and device of an Iub port. Background technique [0002] The Iub port is an interface between the RNC (Radio Network Controller, radio network controller) and the base station NodeB, and is used to transmit data between the RNC and the NodeB. The UU interface is an air interface, which is an interface for data transmission between NodeB and terminal UE. The RNC sends the data requested by the terminal to the Node B through the Iub port, and the Node B then sends the data to the corresponding terminal through the UU port. [0003] When the RNC sends the data requested by the terminal through the Iub port, it is necessary to determine the size of the MAC-d protocol data unit (PDU, Protocol Data Unit). The specific method is: according to the sending capability of the user UU port, according to the configured MAC-d PDU Size, traversal selection of MAC-d PDU siz...
