Description
Technical Field
The present invention relates to mobile communication technology, and in particular, to a method and system for acquiring link detection information from a base station (eNodeB) to a User Equipment (UE) in an LTE system.
Background
With the large-scale commercial use of the LTE base station, the construction and maintenance workload of the LTE base station by each large operator is correspondingly increased. The stability of links among network elements in the whole LTE system is an important concern in the construction of telecommunication networks. As an important part of the overall link, link detection from eNodeB to UE terminal is crucial.
At present, the detection method for the whole LTE system link is more and more mature, but the test scheme specially for the link state between the eNodeB and the UE in the LTE system is less, and the on-line detection scheme is more deficient. In practical application, there are two main schemes for detecting the link, one of which is to use an exclusion method (such as FTP download), and the other is to use a third-party encapsulation device to perform an on-site encapsulation test.
The so-called elimination method is to perform normal service (such as FTP downloading, etc.) on the link to be detected, and if the service is normal, the whole link is normal, and then the link between the eNodeB and the UE is also unproblematic. If the normal service has abnormal conditions such as packet loss, failure and the like, it indicates that the whole link has a problem, and then detects whether the link from the eNodeB to the UE on the whole link is normal through other modes, if so, it can be determined that the link from the eNodeB to the UE has a problem, and if not, it needs to further locate whether the reason causing the abnormality of the whole link appears in the link from the eNodeB to the UE. Therefore, the method for detecting the state of the link from the eNodeB to the UE in the LTE system has a complex process, needs to depend on detection modes of other road sections in the link, and sometimes has an unobvious effect.
In the above scheme of performing the on-station bag filling test by using the third-party bag filling equipment, when a link has a problem, an interface is allocated to the third-party bag filling equipment and the third-party bag filling equipment is accessed into the network, then a test message is filled into one end of the link to be detected by using the third-party bag filling equipment, the receiving condition of the test message is observed at the other end of the link to be detected, if the corresponding test message can be normally received, the state of the link to be detected is normal, otherwise, the link to be detected has an abnormal state.
According to the scheme for performing the on-station bag filling test by using the third-party bag filling equipment, although the detection accuracy can be improved, when the transmission condition information (namely the link detection information) for link detection is acquired, the third-party bag filling equipment needs to be accessed into the original network, so that the topological structure of the original network can be changed, and the normal operation of the service can be influenced. Therefore, the scheme is only suitable for the situation that the link has problems, and when the network topology is complex, the problem of complex implementation caused by the untrustworthiness of other network elements may exist. In addition, because the maintenance personnel are required to carry the filling equipment to operate at the station, on one hand, the workload of maintenance is increased, the personnel investment is increased, and on the other hand, the professional quality requirement of a front-line personnel is higher, so that the labor cost of system maintenance is greatly increased.
Therefore, the traditional link detection scheme from the eNodeB to the UE has the problems of complex detection, low accuracy or no support of online link detection, high implementation difficulty, high cost and the like.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention is as follows: when the link detection is needed, the eNodeB generates a test message according to the preconfigured message parameters and sends the test message to the UE, so that the condition that the detection needs to depend on a third-party encapsulation device can be avoided, the normal operation of the service is not influenced during the detection, and the online real-time detection of the link is favorably realized.
Fig. 1 is a schematic flow chart of a method according to a first embodiment of the present invention, as shown in fig. 1, the embodiment mainly includes:
The step is used for configuring the parameter information for generating and sending the test message in the eNodeB in advance, so that when the link detection is required, the eNodeB can automatically generate the corresponding test message according to the parameter information and send the test message to the UE, and when the transmission condition information for the link detection is acquired, third-party encapsulation equipment does not need to be introduced, so that various problems caused by the dependence on the third-party encapsulation equipment can be effectively avoided.
Preferably, the parameter information preconfigured in this step may include a port number of the test packet, a source address of the test packet, a destination address of the test packet, a length of the test packet, a sending rate, and a sending duration.
In practical application, in order to improve the detection accuracy, multiple sending rates can be set, and each sending rate configures corresponding message sending duration.
In practical application, the parameter information may be configured to the eNodeB through a network management system of the system, and the parameter information may be dynamically adjusted by a person skilled in the art according to needs.
And 102, when a link from the eNodeB to User Equipment (UE) needs to be detected, the eNodeB generates a test message according to the parameter information and sends the test message to target UE specified by the parameter information according to a preset sending interval.
In this step, when a link from the eNodeB to the UE needs to be detected, the eNodeB generates a test packet instead of generating a test packet by a third-party tunneling device, so that the eNodeB can directly and automatically send the test packet on the link without interrupting the link to access the third-party tunneling device, and therefore, information for detecting the link is not required to be acquired after the link is interrupted. Therefore, on one hand, the method is favorable for realizing the on-line detection of the link from the eNodeB to the UE, on the other hand, the link detection is easier to realize, the efficiency of fault location can be improved, the fault occurring interval can be defined more quickly and accurately, and the detection cost is reduced.
In practical applications, the eNodeB may generate a test packet by using various protocols carried on the GTP-U packet, such as an IP protocol, and specifically, a communication protocol used may be selected by a person skilled in the art according to an actual situation, which is not described herein again.
It should be noted that, in this step, the eNodeB periodically sends the test packet to the pre-specified target UE, so that other non-target UEs will not receive the test packet, and normal services of the non-target UEs will not be affected. Therefore, real-time detection of the online link can be supported, and normal traffic of other UEs is not affected.
In this step, the eNodeB generates a test packet according to the preset parameter information, and then continuously transmits the test packet to the designated target UE according to the preset transmission interval. Therefore, maintenance personnel can acquire the state of the link in real time according to whether the receiving condition of the test message of the target UE side is consistent with the corresponding sending condition of the test message recorded by the base station side.
Preferably, the eNodeB may send the test packet to the target UE by using the following method:
and according to the sending interval, sequentially according to each preset sending rate and sending duration combination, continuously sending the test message to the target UE.
In the sending process, the test message is sent according to the combination of the preset multiple sending rates and the sending duration, so that the sending rate and the sending duration of the message are variable, and the link condition can be comprehensively detected.
And 103, carrying out real-time statistics on the receiving condition information of the test message by the target UE.
In this step, the target UE performs real-time statistics on the reception condition information of the test packet, so that the maintenance personnel can obtain the reception condition information for detecting the link state from the target UE, and can compare the reception condition with the corresponding transmission condition recorded by the eNodeB side based on the reception condition to determine whether the link has a fault.
Here, the receiving condition information may specifically include the parameter information corresponding to the test packet, the current statistical duration, and the number of the currently received test packets.
Fig. 2 is a schematic diagram of a system structure corresponding to the above method, and as shown in fig. 2, the link detection system mainly includes:
and the base station eNodeB is used for generating a test message according to preset test message parameter information when a link from the eNodeB to the user equipment UE needs to be detected, and transmitting the test message to target UE specified by the parameter information according to a preset transmission interval.
The target UE is used for carrying out real-time statistics on the receiving condition of the test message; and triggering to determine the state of the link according to the matching result of the receiving situation and the corresponding sending situation of the eNodeB side.
Preferably, the sending the test packet to the target UE specified by the parameter information includes:
and according to the sending interval, sequentially according to each preset sending rate and sending duration combination, continuously sending the test message to the target UE.
Preferably, the parameter information includes a port number of the test packet, a source address of the test packet, a destination address of the test packet, a length of the test packet, a sending rate, and a sending duration.
Preferably, the receiving condition information includes the parameter information corresponding to the received packet, the current statistical duration, and the number of the currently received test packets.
According to the technical scheme, the eNodeB does not need to increase testing equipment, does not need to participate in a core network element, does not change a network structure, automatically extracts information according to preset parameters, assembles corresponding test messages and sends the test messages to the target UE, does not influence normal services of other UEs while carrying out online detection on the target UE, is beneficial to realizing real-time detection of an online link, and is easy to realize, high in efficiency and high in accuracy.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
