Problems solved by technology

However, the evolution from the traditional wireless access network architecture to this structure will bring the problem of high deployment costs, and because of the centralized deployment of DUs, disaster recovery cannot be achieved, resulting in poor site availability. Some devices controlled by DU may not work

Embodiment 1

[0237] An embodiment of the present invention provides a wireless access method, the method is applied to switching equipment, in which the basic digital output unit DU is deployed in the site, specifically in the wireless access corresponding to the LTE network as shown in 1 System 100 is described below, assuming figure 1 The wireless access system 100 shown includes three basic DUs, respectively DU101, DU102, and DU103. The system 100 also includes a radio frequency processing unit (Radio process unit, RU), a transmission network 104, and a switching device 105. figure 2 As shown, the method includes:

[0238] 201. The switching device receives a first data packet sent by a first basic DU.

[0239] Specifically, the embodiment of the present invention does not specifically limit the number of the first basic DU, which may be one or several, and any basic DU with the technical characteristics of the first basic DU in the embodiment of the present invention may be It is ca...

Embodiment 2

[0327] An embodiment of the present invention provides a wireless access method, the method is applied to switching equipment, in which the basic digital output unit DU is deployed in the site, specifically in the wireless access corresponding to the LTE network as shown in 3 System 300 is described, as Figure 12 As shown, the method includes:

[0328] 1201. The switching device receives a first data packet sent by a first basic DU.

[0329] Specifically, the embodiment of the present invention does not specifically limit the number of the first basic DU, which may be one or several, and any basic DU with the technical characteristics of the first basic DU in the embodiment of the present invention may be It is called the first basic DU.

[0330] Exemplary, in image 3 , the first basic DU can be DU301, DU302, or DU301 and DU302.

[0331] It should be noted that the "first" in the first data packet has no special meaning, and is only used to distinguish it from the "secon...

Embodiment 3

[0606] An embodiment of the present invention provides a switching device 2000, specifically as Figure 20 As shown, the switching device 2000 includes a receiving unit 2001 , a determining unit 2002 , and a sending unit 2003 .

[0607] The receiving unit 2001 is configured to receive a first data packet sent by a first basic digital processing unit DU, and send the first data packet to the determining unit 2002, wherein the basic DU is deployed in a site.

[0608] The determining unit 2002 is configured to receive the first data packet sent by the receiving unit 2001, and determine to send the first data packet to the second basic DU for collaborative processing, and then send the first data packet to the sending unit 2003.

Abstract

The embodiment of the invention provides a method, device and system for wireless access. The device may achieve mutual cooperative data transmission and processing between station on the basis of low-cost disposal and high usability in order to improve network performance. In the method, a basic DU is disposed in a station. The method may include: receiving a first data packet transmitted from a first basic DU with a switching device; determining to transmit the first data packet to a second basic DU to be cooperatively processed; transmitting the first data packet to the second basic DU in order that the second basic DU cooperatively process the first data packet and a second data packet, wherein the data type of the second data packet is same as that of the first data packet. The method, device and system for wireless access is applied to communication field.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method, device and system for wireless access. Background technique [0002] With the development of wireless communication technology, the wireless access network architecture is no longer unitary, and now two existing wireless access network architectures are provided: [0003] 1. Traditional wireless access network architecture, in which the baseband is deployed at the site. Taking Long Term Evolution (LTE) as an example, the access network adopts the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial RAN, E- The structure of UTRAN) is mainly connected by the base station and the access gateway through the S1 interface, and the base stations are connected through the X2 interface. This architecture has certain advantages in site deployment and high reliability, but it cannot perform inter-site collaborative data transmi...
