Problems solved by technology

It can be seen that the transmission mode of this FP frame will greatly affect the transmission efficiency on the Iub port, resulting in the reduction of the transmission performance on the Iub port, thereby reducing the performance of the entire system
[0011] In fact, in addition to the FP frames transmitted on the Iub port, there are other network interface frames that require synchronization when they are transmitted on the IP link, and the above problems also exist, which leads to the reduction of system transmission performance

Embodiment 1

[0085] In this embodiment, the number of repetitions of the network interface frame is used as a characteristic parameter of the channel. According to the characteristic parameter, the same network interface frame is repeatedly sent multiple times, so as to improve the transmission reliability of the network interface frame.

[0086] Figure 4 It is a flowchart of a method for adaptively transmitting 3G network interface frames on an IP link according to Embodiment 1 of the present invention. Such as Figure 4 As shown, the method includes:

[0087] Step 401, the receiving end counts the packet loss rate, and calculates the number of network interface frame repetitions.

[0088] In step 402, it is judged whether the number of frame repetitions of the network interface has changed, and if it is changed, execute step 404 and its subsequent steps, otherwise execute step 403.

[0089] Step 403, the sending end packs and sends the network interface frame according to the number ...

Embodiment 2

[0094] It is assumed that the sending end is a serving RNC (SRNC), and the receiving end is a NodeB. In this embodiment, the network interface frame, ie, the FP frame, is transmitted in the downlink direction. Figure 5 It is the method flowchart of embodiment two. The method includes:

[0095] Step 501, SRNC packs and sends FP frame to NodeB according to FP frame repetition times;

[0096] In this step, the method of packaging the network interface frame is as follows: Image 6shown. The method can be as follows: assuming that the number of repetitions of FP frames is N, the FP frames coming successively on a transmission channel in SRNC are sequence 600, including FP1, FP2, ..., at the first sending moment, SRNC buffers N frames in sequence FP frame, that is, sequence 601, including FP1, FP2, ... FPN, SRNC takes out sequence 601 from the cache and packs it in an IP / UDP packet, and at the same time deletes FP1 at the queue head in the cache, and puts FPN+1 into the cache ...

Embodiment 3

[0111] It is assumed that the sending end is a NodeB, and the receiving end is a serving RNC (SRNC). Figure 7 It is the flow chart of the method of embodiment three. Such as Figure 7 As shown, the method includes:

[0112] Step 701, NodeB packs and sends FP frames to SRNC according to the repetition times of FP frames;

[0113] In this step, the method for packaging the FP frame is as follows Figure 8 shown. The method can be as follows: assuming that the number of repetitions of FP frames is N, the FP frames coming successively on a certain transmission channel in the sending end are sequence 800, including FP1, FP2, ..., at the time of sending each frame, the same FP frames are repeated N times and packed in IP / UDP packets. For example, at the first sending moment, SRNC repeats FP1 N times to form a sequence 801, which is packaged in IP / UDP; at the second sending moment, that is, when the next cycle executes to this step, SRNC repeats FP2 N times to form Sequence 80...

Abstract

A method for adaptively transmitting interface frame of the third generation network in internetworking protocol link packages certain amount of network interface frame into grouping data packet by obtaining channel character parameter in real time and transmitting packaged data packet according to said character parameter for raising transmission performance of network interface frame.

Description

technical field [0001] The invention relates to the transmission technology of the third generation (3G) network interface frame, in particular to a method for adaptively transmitting the 3G network interface frame on an Internet protocol (IP) link. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA) air interface technology, and the UMTS system is usually called a WCDMA communication system. figure 1 It is a structural diagram of the UMTS system. Such as figure 1 As shown, the UMTS system adopts a structure similar to that of the second generation mobile communication system, including a radio access network (Radio Access Network, RAN) 100 , a core network (Core Network, CN) 110 and user equipment 130 . Among them, the wireless access network is used to handle all wireless-related functions, while the CN handles all voice calls and d...
