Embodiment 1

[0040] Embodiment 1, please refer to the attached figure 1 , is a flow diagram of obtaining available frequencies when the pico base station is carried by a user from city A in country C to city B in country C, that is, when the pico base station is in a domestic roaming state.

[0041] Step 110, after the Femto base station is powered on, it obtains the network address assigned to itself, wherein the specific way of obtaining the network address is that the Femto base station broadcasts the MAC address of the Femto base station to a Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol) server, and obtains The network address IP1 assigned by the DHCP server to the Femto base station; the specific way for the Femto base station to obtain the network address is similar to that of a personal computer. To obtain the network address by assigning the specified network address or other methods;

[0042] Step 120, the femto base station reads the network add...

Embodiment 2

[0054] Embodiment 2, please refer to the attached image 3 , is a schematic diagram of the process of obtaining available frequencies when the pico base station is carried by the user from city A in country C to city Y in country X, that is, when the pico base station is in the state of international roaming.

[0055] Step 310, obtain the network address IP5 assigned to itself after the femto base station is turned on;

[0056] Step 320, the femto base station reads the pre-stored network address IP2 of the femto gateway FGW1 in the home network to which the base station belongs, and sends the authentication information including the network address obtained in step 310 to the femto gateway FGW1;

[0057] Step 330, the femto gateway FGW1 receives the authentication information sent by the femto base station. After the authentication is passed, the femto gateway FGW1 uses the network address IP5 of the femto base station in the authentication information and the corresponding r...

Abstract

The invention discloses a system and a method for determining usable frequency of a micro-micro base station and a relevant device, which aims to solve the problem that the usable frequency can not be determined when the micro-micro base station is in a roaming state. The system comprises a micro-micro base station; a first micro-micro gateway in a hometown network subordinate to the micro-micro base station and a second micro-micro gateway at a visiting place of the micro-micro base station, wherein the micro-micro base station is used for obtaining a network address distributed to the micro-micro base station and transmitting authentication information containing the network address distributed to the micro-micro base station to the first micro-micro gateway according to the stored network address of the first micro-micro gateway; the first micro-micro gateway is used for determining the second micro-micro gateway visited by the micro-micro base station at present according to the network address contained in the authentication information when the roaming state of the micro-micro base station is determined, requesting the usable frequency at the visiting place to the second micro-micro gateway and transmitting the requested usable frequency to the micro-micro base station; and the second micro-micro gateway is used for transmitting the usable frequency at the visiting place to the first micro-micro gateway.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a system and method for determining available frequencies of a pico base station, a pico base station, and a pico gateway. Background technique [0002] The purpose of Long Term Evolution (LTE, Long Term Evolution) technology is to provide users with a full range of mobile multimedia experience. However, in some cases, such as in a cell with dense users, all users are provided with Satisfactory data communication service is relatively difficult, so the prior art proposes to use a femto base station to solve this problem. [0003] The transmission power of a pico (Femto) base station is much smaller than that of a macrocell base station (eNodeB), and it can be deployed indoors in homes and companies to provide high-speed data communication services for users within the coverage area. The Femto base station can not only meet the call service requirements of th...
