Problems solved by technology

In the above example, from sequence number 1567 to 1571, a total of 5 RLP packets are sent, 2 of which are required to be retransmitted and discarded due to out-of-order. If the out-of-order condition of the transmission network remains unchanged, these unnecessary retransmissions Data occupies 40% of Abis and air interface bandwidth, resulting in a huge waste of bandwidth

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0033] A first embodiment of the present invention relates to a packet transmission method. In this embodiment, a sorting buffer is set in the base station, for example, the buffer can be set on a channel board of the base station. After the base station receives the packet from the Abis interface, if the packet currently received by the base station is not the currently expected packet, it buffers the packet currently received by the base station to the buffer; if there is a currently expected packet in the buffer, it sends the currently expected packet. The specific process is shown in Figure 2.

[0034] In step 210 of Figure 2, the base station receives the packet.

[0035] In step 220 of FIG. 2 , the base station judges whether the...

Abstract

The invention relates to the communication field, which discloses a packet transmission method and a base station equipment and improves a bandwidth utilization efficiency of an Abis and an air interface. In the invention, if a current packet received by the base station is not an anticipant packet at present, the current packet received by a caching base station is transmitted to a buffer; and if the present anticipant packet exists in the buffer, the present anticipant packet is transmitted. The present anticipant packet is a next packet, which follows a recently transmitted packet.

Description

technical field [0001] The invention relates to the communication field, in particular to the packet transmission technology. Background technique [0002] In the Code Division Multiple Access 2000 Evolution Data Optimized (CDMA2000 EV-DO) system, the interface (Abis) between the base station controller (Base Station Controller, referred to as "BSC") and the base station Due to the diversity of link networking, the data packets sent in the system may be out of order. [0003] In the prior art, the base station does not perform any processing on the received out-of-sequence packets, but directly forwards the packet to the terminal each time it receives a packet from the BSC, as shown in FIG. 1 . [0004] The out-of-sequence packets are processed by executing a radio link protocol (Radio Link Protocol, "RLP") in the terminal, wherein, RLP is a guarantee protocol for air interface transmission stipulated in the CDMA2000 EV-DO protocol. The implementation principle is as follo...
