Embodiment 1

[0038] Such as figure 1 As shown, it is a schematic structural diagram of a wireless signal processing system provided by an embodiment of the present invention, including a first signal processing unit 11 and a second signal processing unit 12, and the first signal processing unit and the second signal processing unit are connected by The signal buffer unit 13 is connected, wherein:

[0039] The first signal processing unit 11 is configured to, after receiving the wireless signal, process the received wireless signal according to its own signal processing sequence and store it in the signal buffer unit;

[0040] a signal buffer unit 13, configured to store the wireless signal processed by the first signal processing unit 11;

[0041] The second signal processing unit 12 is configured to read the wireless signal from the signal buffer unit 13 according to its own signal processing sequence, process it and output it.

Embodiment approach

[0042]During specific implementation, if it is divided according to the signal processing direction, for example, if the wireless signal to be processed is a downlink signal, that is, the wireless signal received by the first signal processing unit 11 is a downlink signal, then the first signal processing unit 11 can be The functional processing unit on the virtual machine in the C-RAN system can also be the functional processing unit on the baseband single board in the integrated base station system or the distributed base station system, and is used to realize the baseband processing function; the second signal processing unit 12 can be The radio frequency related function processing unit is used to realize the functions related to radio frequency processing. In this implementation manner, the first signal processing unit 11 may be a functional processing unit that can be flexibly migrated or switched, and the second signal processing unit 12 may be a fixed functional process...

Embodiment 2

[0059]In order to reduce the occupation of the storage space of the wireless communication system, for some expected function migration or switching, that is, application scenarios where the function migration or switching time is known, the wireless signal processing system provided in the embodiment of the present invention may also include connection management unit. The connection management unit is used to establish the relationship between the first signal processing unit 11 and the second signal processing unit 13 when the signal processing function of the first signal processing unit 11 or the second signal processing unit 13 needs to be migrated / switched. The data exchange connection between the above-mentioned signal buffer units.

[0060] That is to say, during specific implementation, the signal buffer unit located between the transferable or switchable functional processing unit and the fixed functional processing unit may be set up at the beginning of the system ...

Abstract

The invention discloses a wireless signal processing method, device and system which are used for ensuring wireless air interface signals not to be interrupted in the virtual machine migration or master-slave board switching process and improving the user experience. The wireless signal processing system comprises a first signal processing unit and a second signal processing unit, and is characterized in that the first signal processing unit and the second signal processing unit are connected through a signal caching unit, wherein the first signal processing unit is used for receiving wireless signals, processing the received wireless signals according to a signal processing time sequence thereof and then storing the processed signals into the signal caching unit; the signal cashing unit is used for storing the wireless signals processed by the first signal processing unit; and the second signal processing unit is used for reading the wireless signals from the signal caching unit according to a signal processing time sequence thereof, processing the wireless signals and then outputting the processed wireless signals.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless signal processing method, device and system. Background technique [0002] There are mainly two types of wireless access network base station equipment: integrated base station and distributed base station. The so-called integrated base station means that a baseband processing unit (BBU, baseband unit) and a remote radio frequency unit (RRU / RRH, radio remote unit / head) are implemented in the same physical device. In the distributed base station, the BBU and RRU are respectively implemented in different physical devices, and the two communicate through the front-end transmission interface. The hardware platform realized by the above-mentioned baseband processing unit is also mainly composed of two types: one is the dedicated baseband processing single board deployed in the existing network, which is mainly composed of digital signal processing (D...
