Problems solved by technology

[0004] In this case, although REs can be shared between 3G and LTE, RECs are dedicated to each system. Therefore, if you want to connect REs and RECs according to the above-mentioned CPRI, you must separately prepare RE / REC systems corresponding to 3G. In the RE / REC system corresponding to LTE, there is a problem that RE cannot be used efficiently

Abstract

A relay device (100), upon receiving a Hyper Frame (HFN) from an RE (30), sends a predetermined information, such as control information included in the received Hyper Frame, by adding said information to a Hyper Frame to be sent to an REC (21) from the relay device (100). Specifically, the relay device (100) adds said information to the Hyper Frame to be sent to the REC (21), and sends said information within a predetermined time frame, which begins from when the Hyper Frame was received from the RE (30). Moreover, the RE (30) sends the Hyper Frame to the relay device (100) at a faster cycle than the Hyper Frame transmitting cycle when the RE (30) and the REC (21) are directly connected.

Description

technical field [0001] The present invention relates to a wireless base station system including a relay device connectable to a wireless device and a plurality of wireless device control devices having different wireless communication methods, and to the relay device. Background technique [0002] In recent years, the interface specification between the radio equipment (RE) that transmits and receives radio signals with the mobile station and the radio equipment control equipment (REC) that performs the control of the radio equipment has been established by the Common Public Radio Interface (RPRI )) were standardized (for example, refer to Non-Patent Document 1). According to this interface standard, REs and RECs manufactured by different manufacturers can be easily connected, and compatibility can be ensured. [0003] However, in the mobile communication system, during the transition period to a new wireless communication system, systems based on the previous wireless com...
