Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Example one

According to the embodiment of the invention, the communication method of the base transceiver station is provided, the port B serving as a debugging function can be used for realizing the communication function, and the waste of port resources caused when the port B is not used as the debugging port is avoided.

Fig. 1 is a flowchart of a communication method of a base transceiver station according to an embodiment of the present invention, and as shown in fig. 1, the method may include the following steps (step S102-step S104):

step S102, when the BTS monitors that the port B of the BTS receives the data message, whether the data message is a preset characteristic message is judged.

In step S104, when the determination result is yes, the BTS performs communication using its port B.

According to the embodiment of the invention, when the BTS detects that the port B of the BTS receives the data message, whether the data message is the preset characteristic message is judged, and when the judgment result is yes, the BTS utilizes the port B to carry out communication, so that the port B can also be used as a communication port to realize a communication function, thereby fully utilizing port resources and avoiding the problem of resource waste caused by the fact that the port B is only used as a debugging function.

In a preferred implementation manner of the embodiment of the present invention, the BTS receives the data packet from the port B of the BTS, and can determine whether the received data packet is the preset feature packet, and perform communication using the port B when determining that the sensed data packet is the preset feature packet. For example, when receiving an ethernet frame addressed to port a of the BTS from port B, the BTS communicates port B of the BTS, so that port B can perform data transmission with port a as a communication port. Alternatively, when receiving a Dynamic Host Configuration Protocol (DHCP) message from port B, the BTS may communicate with port B of the BTS. The feature message in the embodiment of the present invention may include, but is not limited to, an ethernet frame and/or a DHCP message of a port a of the BTS having a destination hardware address, and may also be other data messages when the port is used as a communication port.

The BTS communicates by using the port B of the BTS as a communication port, and the port B and the port A of the BTS transmit data messages together. During the data transmission process or in an idle state, the end can be prohibited from communicating when port debugging is needed. In a preferred implementation manner of the embodiment of the present invention, in order to implement that the port B can adaptively switch between the two working modes of the debugging function and the communication function, the method may further include: the BTS continues to monitor the data message received from the port B; and when the BTS determines that the destination Internet protocol IP address and/or the source IP address of the currently received data message belong to the debugging IP network segment, the communication is forbidden by using the port B. Through the preferred embodiment, the port B can be adaptively switched between the two working modes of the debugging function and the communication function, so that the port B can be used as both the debugging port and the communication port, and the utilization efficiency of port resources is improved.

In another preferred implementation of the embodiment of the present invention, after the BTS communicates with the port B of the BTS, the BTS may further determine whether there is a state change from disconnection to connection in the port B within a preset time, and if there is the state change, the BTS prohibits the communication with the port B of the BTS. For example, the BTS may monitor the connection state of the port B in real time, determine whether the port B has changed from off-to-on state within the last 30 seconds, and prohibit the BTS from communicating with the port B of the BTS if there is a change in off-to-on state. Through the preferred embodiment, when the physical connection state of the port B of the BTS is changed, the port B of the BTS is forbidden to be used for communication, and the port B enters a debugging function, so that debugging personnel can conveniently carry out port debugging.

For example, the port B of the BTS is currently in a communication function, and transmits a data packet of the BTS together with the port a, so that a tester can perform Telnet login and check operation information of the BTS by using a computer, and when receiving the data packet, the BTS judges whether a destination IP address of the data packet is consistent with a network segment of a debug IP. If yes, judging whether the state change from disconnection to connection of the port B occurs within the last 30s, if yes, determining that the Ethernet line of the port B is pulled out of the switch and connected to a computer for testing, at the moment, the BTS forbids the communication by using the port B of the BTS, and testing personnel test the BTS to check the operation information.

Port convergence (TRUNK) is an important approach for bandwidth expansion and link backup. TRUNK binds a plurality of physical ports together to be used as a logical port, and can superpose the broadband of a plurality of groups of ports for use. The TRUNK technology can realize the function that a plurality of links inside the TRUNK are backup to each other, namely when one link fails, the work of other links is not influenced, and meanwhile, the flow balance among the plurality of links can be realized. The bandwidth between the switch and the network node can be increased by combining 2 or more physical ports into a logical path through the configuration of software settings, and the bandwidths belonging to the several ports can be combined to provide higher bandwidth and greater throughput. The logical link formed by the port binding is called an ethernet channel (the ethernet channel mode is shown in table 1), and can be realized by setting a switch.

Table 1 ethernet channel mode table

Therefore, in a preferred implementation manner of the embodiment of the present invention, the BTS may perform TRUNK setting, bind port a and port B of the BTS to TRUNK, and the BTS performs communication by using the port B to which TRUNK is bound. After binding is completed, the link of the port A and the link of the port B form a redundant communication link, the link bandwidth is increased, and the two physical links can simultaneously complete data receiving and sending tasks and back up each other, so that the requirements of load balancing and the like are conveniently realized. Accordingly, the BTS can perform the detrack setting, and the port B on which the detrack setting has been performed is detrack set, and the BTS prohibits communication using the port B. After TRUNK setting is removed. The port B enters a debugging function, and a tester can perform corresponding test operation on the BTS.

Example two

According to the embodiment of the invention, the method collects the port information of the BTS at regular time, monitors the information of the data packet received by the port B, and logically binds the ports of the BTS into a channel to perform the TRUNK binding operation if the information meets the category of the characteristic message. Meanwhile, the operator may remove the communication line of the port B, directly perform Telnet operation from the port B through a Personal Computer (PC), check the operation information of the board, and perform an operation of releasing the TRUNK. The two working modes can be switched mutually without any manual configuration. Through the specific embodiment of the invention, the BTS can adaptively bind or unbind TRUNK and can realize timely port aggregation.

In a Base Station Subsystem (BSS) as shown in fig. 2, the BTS and a Base Station Controller (BSC) may be connected via an ethernet switch, and the connection line may be an ethernet twisted pair. And setting two ports of the S/W into an on-mode Ethernet channel. When the base station is powered on, a timer is set to enter a polling state, and the link state of each network port of the base station is inquired. In the embodiment of the invention, the conversion of the port function includes two aspects of binding TRUNK and unbinding TRUNK.

Strategy for binding Trunk

Determining whether to bind TRUNK according to the packet receiving state of the port B: if receiving an ethernet frame or DHCP message from port B with a destination hardware address of port a, binding port a and port B of the board to TRUNK, fig. 3 is a flowchart of binding TRUNK according to an embodiment of the present invention, and as shown in fig. 3, the method may include the following steps (step S302-step S312):

step S302, the port B of BTS receives the data message.

Step S304, the bottom layer of BTS judges whether the data message received by port B is a characteristic message, if yes, the step is entered

Step S306; otherwise, ending.

Step S306, the bottom layer of the BTS forwards the data packet received by the port B to the protocol stack for processing. If the received data message is a normal ethernet frame, go to step S308; if the received data packet is a broadcast frame, the process proceeds to step S310.

Step S308, judging whether the destination MAC address of the received data message is the MAC address of the port A, if so, entering step S312, otherwise, ending.

Step S310, judging whether the flag bit in the received data message is valid, if yes, entering step S312, otherwise, ending.

In step S312, the BTS sets true, and port B is used as a communication port for communication.

Specifically, as shown in fig. 3, when the subsystem at the bottom receives an ethernet frame or a DHCP message from the port B, where the destination hardware address is the port a hardware address, the two types of messages are sent to the protocol stack, and when the protocol stack receives the two types of feature messages, the feature flag bit of the message is set to be valid (denoted as the message received from the port B), and then the following processing is performed:

if the frame is a common Ethernet frame, the frame is forwarded to an Ethernet packet receiving module in the BTS for processing, and if the destination hardware address is the hardware address of the port A, TRUNK is set. If the message is broadcast, judging whether the corresponding characteristic flag bit is valid in the DHCP processing flow, and setting TRUNK. After setting TRUNK, port B of BTS enters communication port state, and can transmit data packet together with port a.

Strategy for unbinding Trunk

An Address Resolution Protocol (ARP) is used to convert a network address (32 bits of an IP address) of a computer into a physical address (also called a Media Access Control (MAC) address, 48 bits). The ARP protocol is a protocol belonging to the link layer, and data frames in ethernet arrive from one host to another within the network by determining the interface based on a 48-bit ethernet address (hardware address) rather than a 32-bit IP address. Therefore, the hardware address of the destination is known to send the data. If port B receives ARP message of debugging IP network segment (such as 192.0.0.0), if port B of BTS already binds TRUNK, then unbind TRUNK. Fig. 4 is a flowchart of unbundling TRUNK according to an embodiment of the present invention, and as shown in fig. 4, the method may include the following steps (step S402-step S408):

in step S402, the BTS captures an ARP packet of the destination IP network segment as a debug IP network segment (e.g., 192.254).

At step S404, the BTS checks for link on-off changes within the last 30 seconds.

And step S406, the BTS judges whether the link is changed in on-off state, if so, the step S408 is carried out, and if not, the operation is finished.

Step S408, the BTS sets a TRUNK, prohibits the port B from communicating, and the port B is used as a debugging port.

Specifically, the tester can directly connect to the BTS by using the PC to perform Telnet login and check the operation information of the board. After the base station is powered on, the matching function of the ARP message can be realized. And after receiving the ARP packet, the BTS judges whether the IP is consistent with the network segment of the debugging IP or not. If yes, judging whether the physical network port is switched from off to on in the last 30s, if yes, determining that the Ethernet line of the port B is pulled out from the switch and is connected to the PC, the BTS binds TRUNK, and the port B of the BTS enters a debugging port state.

After the base station is powered on, if the connection line is changed and the link is interrupted, the procedures of binding TRUNK and unbinding TRUNK can be carried out again, and the TRUNK setting of the port B of the BTS is updated.

EXAMPLE III

According to the embodiment of the present invention, there is also provided a communication apparatus of a base transceiver station, which is disposed in a BTS and can implement the method for switching the port function provided in the above-mentioned embodiment of the present invention.

Fig. 5 is a schematic diagram of a communication apparatus of a base transceiver station according to an embodiment of the present invention, and as shown in fig. 5, the apparatus mainly includes: the device comprises a listening module 10, a first judging module 20 and a communication module 30. Wherein, the interception module 10 is configured to intercept that the port B of the BTS receives the data packet; a first determining module 20, coupled to the intercepting module 10, configured to determine whether the data packet is a preset feature packet when the intercepting module 10 intercepts the data packet received by the port B of the BTS; and a communication module 30, coupled to the first judging module 20, for performing communication using the port B when the judgment result is yes.

According to the embodiment of the invention, when the interception module 10 of the BTS intercepts the data message received by the port B of the BTS, the first judgment module 20 judges whether the data message is a preset characteristic message, and when the judgment result is yes, the communication module 30 is triggered to communicate by using the port B of the BTS, so that the port B can also be used as a communication port to realize a communication function, thereby fully utilizing port resources and avoiding the problem of resource waste caused by the fact that the port B is only used as a debugging function.

In a preferred implementation manner of the embodiment of the present invention, when the intercepting module 10 of the BTS intercepts a data packet received from the port B as an ethernet frame whose destination hardware address is the port a of the BTS, the communication module 30 performs communication by using the port B of the BTS, so that the port B can perform data transmission with the port a as a communication port. Alternatively, when receiving a DHCP message from port B, the communication module 30 performs communication using port B of the BTS. In the embodiment of the present invention, the feature packet may include, but is not limited to, an ethernet frame and/or a DHCP packet addressed to port a of the BTS, and may also be other data packets when the port is used as a communication port.

After the communication module 30 of the BTS performs communication using the port B of the BTS, the port B serves as a communication port and transmits a data packet together with the port a of the BTS. During data transmission or in an idle state, when debugging is needed, communication through the port B of the BTS may be prohibited. In a preferred implementation manner of the embodiment of the present invention, in the apparatus shown in fig. 6, in order to implement that port B can adaptively switch between the two operation modes of the debugging function and the communication function, the apparatus further includes an intercept disabling module 40. The module 10 is further configured to continue to listen to the data packet received from the port B, and the disabling module 40 is configured to disable communication using the port B when determining that the destination IP address and/or the source IP address of the currently received data packet belong to the debug IP network segment. Through the preferred embodiment, the port B can be adaptively switched between the two working modes of the debugging function and the communication function, so that the port B can be used as both the debugging port and the communication port, and the utilization efficiency of port resources is improved.

In a preferred implementation of the embodiment of the present invention, as shown in fig. 7, the apparatus may further include: the second determining module 50 is configured to determine whether there is a state change from off to on in the port B within a preset time, and if there is the state change, the triggering prohibiting module 40 prohibits the communication using the port B. For example, the BTS may monitor the connection status of the port B in real time and determine whether the port B has changed from off-to-on status within the last 30 seconds, and if the off-to-on status has changed, the BTS disabling module 40 disables communication using the port B. Through the preferred embodiment, when the physical connection state of the port B of the BTS is changed, the port B is switched to a debugging state, so that debugging personnel can conveniently debug the port.

In another preferred implementation of the embodiment of the present invention, as shown in fig. 8, the communication module 30 may include: a first setting unit 302, configured to perform port convergence TRUNK setting, and bind a port a and a port B of a BTS with TRUNK; a communication unit 304, configured to perform communication using the port B to which the TRUNK is bound. After the binding is completed, the link of the port B forms a redundant communication link, the link bandwidth is increased, and the two physical links can simultaneously complete data receiving and transmitting tasks and back up each other, so that the requirements of load balancing and the like are conveniently realized. Accordingly, as shown in fig. 9, the disabling module 40 may include: a second setting unit 402 for performing a detrack setting for port B for which a retry setting has been performed; a disabling unit 404 configured to disable communication using the port B. After the unbinding is completed, the tester can perform corresponding test operation on the BTS.

From the above description, it can be seen that the present invention achieves the following technical effects: when the BTS monitors that a port B of the BTS receives a data message, whether the data message is a preset characteristic message is judged, and when the judgment result is yes, the BTS utilizes the port B to communicate, so that the port B can also be used as a communication port to realize a communication function, thereby fully utilizing port resources, avoiding the problem of resource waste caused by the fact that the port B is only used as a debugging function, binding the port A and the port B through TRUNK setting, forming a redundant communication link by the link of the port B, simultaneously communicating with the link of the port A, increasing the link bandwidth, simultaneously completing data receiving and sending tasks and mutually backing up by two physical links, and being convenient for realizing the requirements of load balance and the like. After binding is completed, the BTS continues to monitor the data message received from the port B, and when the BTS determines that the target IP address of the currently received data message belongs to the debugging IP network segment, the communication by using the port B is forbidden, so that the port B can be adaptively switched between two working modes of a debugging function and a communication function, the port B can be used as a debugging port and a communication port, and the utilization efficiency of port resources is improved.
