Multimode converging and combining method and device thereof

Abstract

The invention relates to a multimode converging and combining method and a device thereof. The multimode converging method comprises the following steps: the multimode converging method is characterized by comprising the steps of receiving data from a multimodal base band unit (BBU), separating downlink business data from operation maintenance data, generating channel allocation according to the operation maintenance data, selecting the downlink business data with a corresponding mode according to the channel allocation to combine with the corresponding operation maintenance data; and then sending the combination of the downlink business data and the operation maintenance data to a corresponding remote radio unit (RRU). As the multimode converging and combining method and the device thereof are used for achieving functions such as multimode multiplexing, PN multiplexing and the like, the complexity of a multimode system can be lowered and functions of sharing a common optical fiber by multimode and the like can be provided.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for multi-mode convergence and combination. Background technique [0002] In the field of wireless communication, there are many standards such as Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (Long Term Evolution, LTE), Worldwide Interoperability for Microwave Access (Wimax), etc. With the development of communication technology, there is a demand for the coexistence and gradual evolution of multiple standards. In the existing multi-mode coexistence communication system, multiple systems are completely independent or one of the systems performs the functions of convergence and channel combination. [0003] In the prior art, there are completely independent schemes for multiple formats such as figure 1 As shown (taking the coexistence system of...

Problems solved by technology

The disadvantage of this solution is: when the multi-mode is independently configured, there is the problem that the optical fiber transmission from the base station to the remote radio unit cannot be shared; when the multi-mode is independently configured, there is also the problem that the remote radio module cannot be shared in the same frequency band;

After researching the existing technology, the inventor found that the disadvantage of the above solution is that: the content of multiple formats is aggregated by one of the formats, which increases the complexity of the aggregated formats; the aggregation mode is tightly coupled with the mode, which reduces the flexibility of multi-mode coexistence characteristics; the aggregation mode is tightly coupled with the mode, which is not conducive to the smooth evolution among multiple standards
