Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is to be understood that described embodiment is only part of the embodiment of the present invention, rather than whole implementation Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made Every other embodiment, belongs to the scope of protection of the invention.

Fig. 1 is the flow chart for the interconnection error-detecting method that one embodiment of the invention provides, including：

Step 101：First radio equipment controller (Radio equipment Controller, REC) by its first Port sends detection messages to receiving port.

Wherein, the first REC generates detection messages according to first port, and the detection messages include the end of the first port Message ceases；The port information is used to uniquely determine the port；

The first port and receiving port can belong to the first REC；Or the first port belongs to described First REC, the receiving port belong to the REC different from the first REC.

In the present embodiment, port A is sending port, and port B is receiving port, and port A and port B can belong to port REC belonging to A, port B can also belong to the REC different from the REC belonging to the A of port.

Include port A port information in the detection messages that port A is sent, the port information can uniquely determine network In port A, the sending port A of the port A port informations of oneself, the port information can be port address.

Specifically, port address can with but be not limited to ether net mode, electronic tag mode or random counting method to mark Show port information；

Preferably, ethernet address indicates port A and port B, such as

End	Addressing information
		A	0x0008000000000000+16BIT CR
B	0x0008111111111111+16BIT CR

Table 1

Wherein, the port in network all indicates port with Ethernet addressing mode, and there is unique port each port Address determines port information；

The detection messages are carried on the spare field of CPRI data frames；The CPRI spare fields include the first control Word, wherein the detection messages are divided into multistage according to byte length, first control word is used to carry the detection messages Each section.

Optionally, the spare field of the CPRI includes the first control word and the second control word, wherein, the detection messages It is divided into multistage according to byte length, first control word is used to carry every section of segment number, and second control word is used to hold Carry one section of detection messages corresponding to every section of segment number.

In the present embodiment, port information is carried in CPRI data frames and is sent to port B by port A, specifically, can pass through Port A port information is sent to port B by the following manner by CPRI data frames：

By taking CPRI data frames under 1228.8Mbps line rates as an example, the length of the control word of each basic frames of CPRI is 2 Byte, port A address information is divided into 10 sections by the port address of the port A shown in table 1 according to the length of byte, such as table Shown in 2,

0th section	0x00
		2nd section	0x08
3rd section	0x00
		…	…
7th section	0x00
		8th section	The high 8BIT of 16 CRC checks
9th section	The low 8BIT of 16 CRC checks

Table 2

By in the first character section of each section of (Z.16.0) being carried in the basic frames of CPRI control word, control word (Z.16.0) control word (Vendor Specific) is reserved for manufacturer, as needed, can be also carried in other control words, such as Shown in table 3；

Table 3

Port A port information can be carried to CPRI data frames according to the order of such as the 0th section to the 9th section of sequencing In, it can also be smoothly carried to according to other in CPRI data frames, receiving port parses exit port A end according to corresponding order Message ceases.

Optionally, port A port information can also be sent to port B by CPRI data frames in the following manner：

By taking CPRI data frames under 1228.8Mbps line rates as an example, the length of the control word of each basic frames of CPRI is 2 Byte, port A address information is divided into 10 sections by the port address of the port A shown in table 1 according to the length of byte, such as table Shown in 4, the segment number by every section is that deviation post is carried in the first byte of the first control word, is deviation post by every section of segment number Corresponding Deta bearer is into the first byte of the second control word, as needed, can also be by deviation post and deviation post pair The Deta bearer answered is into other idle bytes of control word.

Table 4

The detection messages of port A transmission are sent to by detection messages by being carried in CPRI data frames, by transparent transmission Port B, as shown in figure 5, the transparent transmission refers to transmit business of the network regardless of transmission, only it is responsible for the business for transmitting needs Destination node is sent to, while ensures the quality of transmission, without handling the business of transmission.

Port A can periodically send detection messages to port B, can also send detection messages as needed to port B, not limit herein.

Step 102：Receiving port receives the detection messages that are sent by CPRI data frames of first port, belonging to receiving port REC detect the opposite end end of the receiving port that the REC belonging to port information and receiving port in the detection messages is pre-seted Whether the port information of mouth is consistent.

Wherein, the port information of the Peer-Port of default receiving port is stored in reception by the REC belonging to receiving port In REC belonging to port, when receiving port receives the detection messages that first port sends, the REC belonging to receiving port sentences Whether the port information of the Peer-Port of the disconnected receiving port pre-seted is consistent with the port information in detection messages；

In the present embodiment, the detection messages of port B receiving ports A transmissions, the REC belonging to the B of port judges port A port Whether information is consistent with the port information of the port B pre-seted Peer-Port, i.e. port A port address and the end pre-seted Whether the port address of mouth B Peer-Port is consistent；

Step 103：If the receiving terminal that the REC belonging to port information and receiving port in the detection messages is pre-seted The port information of the Peer-Port of mouth is inconsistent, and the REC belonging to the receiving port determines connection error.

Wherein it is determined that connection error can be storage incorrect link information, connection error information is sent to other controls Equipment and alerting tone or warning light are shown.

In the present embodiment, it is assumed that port B Peer-Port is port A, i.e. port B port address and port A port Address uniquely corresponds to, then the port information in the detection messages that B is received when port is not port A port information, then REC belonging to the B of port determines connection error.

, can be with when the annular physics link connection mistake in same CPRI networks using the method for the present embodiment Automatic detection goes out connection error and the very first time notifies user without manually investigating connection error, to improve exclusion connection The efficiency of mistake, improve the stability of network.
