Problems solved by technology

[0006] In the prior art, data scheduling methods include maximum weight matching, extreme weight matching, parallel iterative matching, and sliding iterative cycle matching. However, due to the variety of service types of users in centralized base stations, these data scheduling methods do not consider different services. characteristics, so it is not suitable for centralized base station structure

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] figure 1 is a schematic diagram of an HSS application scenario provided by an embodiment of the present invention, such as figure 1 As shown, in a super base station application scenario of the embodiment of the present invention, multiple RRHs receive radio frequency data and transmit them to the BBU pool. The RRHs do not belong to any fixed BBU, and the signals sent or received on each RRH are determined by A baseband processing unit in the BBU pool is completed. Multiple RRHs are connected to the HSS through a common public radio interface (Common Public Radio Interface, CP...

Abstract

The invention provides a data exchange method. The method comprises the following steps: receiving BBU port link data; wherein the BBU port link data comprises destination RRH port information and priority information; establishing a connection relationship between the BBU port and the RRH port according to the target RRH port information and the priority information; and transmitting the BBU portlink data to a corresponding RRH port according to the connection relationship. According to the data exchange method provided by the embodiment of the invention, the transmission speed is high, theBBU port link data is transmitted according to the dynamic connection relationship, high-priority data priority transmission is ensured, and the reliability, throughput and resource utilization rate of centralized base station communication are improved.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a data exchange method and device. Background technique [0002] With the development of wireless communication technology and the rapid increase of terminals and business traffic, wireless communication networks are facing more and more energy consumption challenges. Since most of the energy consumption in wireless communication systems comes from communication base stations, in order to reduce the energy consumption of wireless communication networks energy consumption, a centralized base station structure is proposed. [0003] In the centralized base station structure, a single base station no longer exclusively enjoys base station computing resources. The indoor baseband processing units (Building Baseband Unit, hereinafter referred to as BBU) of many base stations are gathered together to form a BBU pool. Through virtualization technology, the load corresponding to the vi...
