Problems solved by technology

[0007] However, method two cannot fundamentally solve the problem that when the IPOA channel is unavailable, the IPOA channel cannot be re-established to maintain the connection between the base station and the base station controller, because when the IPOA channel has a problem and cannot be connected, if the ATM layer The default permanent virtual connection is also unavailable, and when the normal transmission cannot be performed, this method cannot obtain the BOOTP response packet returned by the base station controller to re-establish the IPOA channel
In fact, the failure of the IPOA channel is often caused by the unavailability of the default permanent virtual connection at the ATM layer, such as: the mismatch between the ATM layer and the physical layer caused by operator errors during the frame switching process of the base station controller Causes the default permanent virtual connection at the ATM layer to fail

Embodiment 1

[0026] Embodiment 1. A method for maintaining an IPOA channel of a base station, the flow chart of which is as follows figure 1 shown, including:

[0027] 101. Detect whether the IPOA channel between the base station and the base station controller is normal, if normal, go to step 102; if not, go to step 103.

[0028] In this embodiment, the base station periodically sends detection packets to the base station controller. If no response is received from the base station controller within the preset time period, it is judged that the IPOA channel is abnormal; When the controller receives the response of the detection packet, it judges that the IPOA channel is normal. It can be understood that other detection methods can also be used, such as sending a detection request by the base station controller side, and the condition for judging that the channel is abnormal can also be for example , if no response packet is received after sending the preset number of detection packets co...

Embodiment 2

[0045] Embodiment 2, a method for maintaining an IPOA channel of a base station, the flow chart of which is as follows image 3 shown, including:

[0046] 301. Detect whether the IPOA channel between the base station and the base station controller is normal, if normal, go to step 302; if not, go to step 303.

[0047] In this embodiment, the detection adopts a Ping method, and the detection packet is a Ping detection packet. For a specific detection method, refer to step 101 of Embodiment 1.

[0048] 302. After waiting for a preset time period, turn to step 301.

[0049] 303. Detect whether the default permanent virtual connection between the base station and the base station controller is normal, if normal, go to step 304; if not normal, go to step 305.

[0050] In the present invention, whether the default permanent virtual connection between the base station and the base station controller is normal can be judged according to the alarm mechanism. Generally, the base stati...

Embodiment 3

[0062] Embodiment 3, a method for maintaining a base station IPOA channel, the flow chart is as follows Figure 5 Shown include:

[0063] 501. Detect whether the IPOA channel between the base station and the base station controller is normal, if yes, turn to step 502; if not, turn to step 503.

[0064] In this embodiment, the detection adopts a Ping method, and the detection packet is a Ping detection packet. For a specific detection method, refer to the specific description of step 101 in Embodiment 1.

[0065] 502. Turn to step 501 after waiting for a preset time period.

[0066] 503. The base station periodically sends a bootstrap protocol request in a broadcast manner.

[0067] 504 , judging whether the base station has received the response packet of the bootstrap protocol request returned by the base station controller within the preset time period, if yes, go to step 505 ; if not, go to step 506 .

[0068] If within the preset time length, the base station controller...

Abstract

The invention relates to a method for maintaining the IPOA channel of base station, which is characterized in that: continuously checking if the IPOA channel between the base station and base station controller is normal; when said channel is abnormal, building the default permanent virtual connection between the base station and the controller; and building IPOA channel between base station and controller on said base of default permanent virtual connection; after building the IPOA channel, going on checking. And the invention can solve the problems that when the default connection of ATM layer is unavailable, the IPOA channel can not be built; when the IPOA channel is accident, the IPOA channel can be built when the physical channel between base station and controller is connected, to improve the maintenance property of base station.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for maintaining an IPOA channel of a base station. Background technique [0002] Base station (NODE B), as an important part of the wireless side in the Wideband Code Division Multiple Access (WCDMA) system, has the characteristics of wide distribution, large number, and difficult local management. In order to solve the problem of remote management of the (NODEB) system, it is stipulated in the 3GPP 25.442 agreement that an IPOA (IP Over ATM) channel needs to be established between the base station (NODE B) and the base station controller (BSC or RNC), that is, based on asynchronous Internet Protocol (IP) transport channel in transfer mode (ATM) for centralized remote management at the base station controller side. [0003] Existing method 1, a method for establishing a base station maintenance channel, disclosed in a Chinese patent application with the application...
