Establishing method of maintenance path in mobile communication network and base station node

Abstract

The invention discloses method for building maintenance channel (MC) in mobile communication network, and base station (BS) node. Thus, under each condition of ATM RAN and IP RAN, base station node can automatic build MC in 3G system. Through base station node, based on transmission mode (TM) and interface type to BS controller, the invention obtains IP address needed for building MC of this BS node from the BS controller by using relevant modes: if TM is ATM, then through DHCP procedure to obtain maintenance IP address; if TM is IP, and interface uses PPP protocol, then, through IP address negotiation to obtain access IP address, and through DHCP procedure to obtain maintenance IP address; if TM is IP, and interface is FE,then, through DHCP procedure to obtain both access IP address and maintenance IP address. All configuration information needed for building MC in 'OPTION' field of DHCP frame is one-off transferred to BS node.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the maintenance technology of network nodes. Background technique [0002] Wideband Code Division Multiple Access ("WCDMA") is one of the three mainstream standards of the third generation mobile communication (the 3rd Generation, "3G"). It inherits the existing global mobile communication The system (Global Systems for Mobile communications, referred to as "GSM") features a high degree of standardization and good openness, and has good compatibility and interoperability with the GSM network. It is one of the development trends of mobile communications in the future. [0003] In a WCDMA system, a Radio Access Network ("RAN" for short) side includes a Radio Network Controller ("RNC" for short) and a Node B (NodeB) serving as a base station. Among them, each NodeB is used to receive user equipment (User Equipment, referred to as "UE") signals within the scope of its jurisdictio...

Problems solved by technology

[0014] However, multiple BOOTP requests, the process is more complicated

And this method is not applicable to the IP RAN maintenance channel whose interface type is E1

Because the E1 interface adopts the PPP protocol, the PPP protocol must determine the access IP addresses of both ends when establishing a PPP link. Before the access IP addresses of both ends are determined, information cannot be transmitted through the PPP link, so that the initial information transmission cannot be realized.
