in this embodiment, the tracking identifier may be used to indicate that the terminal is a test terminal. That is, in the mobility process of terminal re-establishment or handover, the target base station may determine that the terminal is a test terminal according to the re-establishment request message carrying the tracking identifier or the handover request message carrying the tracking identifier, and then track and record the signaling corresponding to the terminal after the terminal is re-established or handed over.

Secondly, even if the terminal is switched or reestablished, the base station can continuously track the terminal according to the reestablishment request message or the switching request message carrying the tracking identifier to acquire the signaling. Further, the tracking identifier may be used to indicate that the terminal is a test terminal, that is, the terminal may be quickly located according to the tracking identifier, and a terminal behavior may be identified for network monitoring and analysis.
Example two
Referring to fig. 2, a flowchart illustrating steps of a signaling tracking method according to a second embodiment of the present invention is shown. In this embodiment, the signaling tracking method includes:
step 202, the current base station determines whether the terminal is a test terminal.
In this embodiment, any suitable manner may be adopted to determine whether the terminal is a test terminal. When the access states of the terminals are different, the specific available determination manners may not be completely the same, and the following description will take the first access of the terminal, the handover access of the terminal, and the reestablishment access of the terminal as examples.
First time terminal access
When the terminal is accessed for the first time, the current base station can judge whether the terminal is a test terminal according to the service condition of the terminal or the IP of the terminal. Specifically, the method comprises the following steps:
preferably, a manner of determining whether the terminal is a test terminal may be as follows: when the terminal is accessed for the first time, acquiring the downlink rate of the terminal in a set time period; judging whether the terminal is a test terminal or not according to the downlink rate of the terminal in a set time period; and if the downlink rate of the terminal in a set time period exceeds a set threshold, determining that the terminal is a test terminal.
In another preferred embodiment, a manner of determining whether the terminal is a test terminal may be as follows: when a terminal is accessed for the first time, acquiring an IP (Internet Protocol ) address of the terminal; judging whether the terminal is a test terminal or not according to the IP address of the terminal; and if the IP address of the terminal is consistent with the preset IP address of the test terminal, determining that the terminal is the test terminal.
Second, terminal switching access
When the terminal is switched in, whether the terminal is a test terminal can be judged according to the tracking identifier carried in the switching request message. The handover request message may be sent by a source base station corresponding to the current base station.
Specifically, a possible way to determine whether the terminal is a test terminal may be as follows: when the terminal is switched to access the current base station, the current base station receives a switching request message sent by a source base station; judging whether the terminal is a test terminal or not according to a received switching request message sent by a source base station; and if the switching request message sent by the source base station carries the tracking identifier, determining that the terminal is a test terminal.
Thirdly, the terminal reestablishes the access
In this embodiment, the reestablishing of access by the terminal may include at least two cases: and the terminal reestablishes the source base station to other base stations.
For the case that the terminal reestablishes to the source base station, that is, the base station that the terminal currently reestablishes to is the source base station, a feasible way of determining whether the terminal is a test terminal may be as follows: acquiring original state information of the terminal in the source base station; judging whether the terminal is a test terminal or not according to the original state information; and if the original state information indicates that the terminal is a test terminal, determining that the terminal is the test terminal.
For the case that the terminal is reestablished to another base station, that is, the base station to which the terminal is currently reestablished is another base station, a feasible way of determining whether the terminal is a test terminal may be as follows: when the terminal accesses other base stations for reestablishment, an indication message is sent to the source base station; the indication message is used for indicating the terminal to be reestablished to the other base stations; receiving a reestablishment request message sent by the source base station; judging whether the terminal is a test terminal or not according to the received reestablishment request message sent by the source base station; and if the reestablishment request message sent by the source base station carries the tracking identifier, determining that the terminal is a test terminal.
And 204, when the terminal is determined to be a test terminal, tracking and recording the signaling information of the terminal in the current base station by the current base station.
In this embodiment, any one of the above suitable manners may be selected to determine that the terminal is a test terminal according to actual conditions, and further, when the terminal is determined to be the test terminal, the signaling information of the terminal in the base station is recorded and tracked.
Step 206, when the terminal is reestablished or switched, the current base station writes the tracking identifier into the corresponding reestablishment request message or switching request message.
In this embodiment, the base station may write the tracking identifier into a corresponding reestablishment request message or handover request message, where the tracking identifier written in the reestablishment request message or handover request message may be transmitted to the target base station along with the reestablishment request message or the handover request message when the terminal is reestablished or handed over, and then the target base station may determine that the terminal is a test terminal according to the reestablishment request message carrying the tracking identifier or the handover request message carrying the tracking identifier, and then perform tracking recording on a signaling of the terminal after the terminal is reestablished or handed over. Wherein the target base station may be
It should be noted that, in this embodiment, the tracking identifier may be specifically written into a private field or information element ie (information element) of the corresponding reestablishment request message; or, writing the tracking identifier into a private field or information element IE of the corresponding handover request message.
In summary, in this embodiment, when the terminal is first accessed, whether the terminal is a test terminal may be directly determined according to the service or the IP address of the terminal, and when the terminal is switched to access or reestablishes access, whether the terminal is a test terminal may be directly determined according to the tracking identifier carried in the reestablishment request message or the handover request message, which reduces the interaction link with the core network side, reduces the communication cost, and has strong timeliness. Moreover, once the terminal is identified, whether the terminal is a test terminal can be quickly determined according to the request message in the subsequent moving process, so that the identification efficiency of the terminal is improved.
Secondly, even if the terminal is switched or reestablished, the base station can continuously track the terminal according to the reestablishment request message or the switching request message carrying the tracking identifier to acquire the signaling.
Further, the tracking identifier may be used to indicate that the terminal is a test terminal, that is, the terminal may be quickly located according to the tracking identifier, and a terminal behavior may be identified for network monitoring and analysis.
EXAMPLE III
With reference to the foregoing embodiments, the present embodiment describes the signaling tracking method in detail through several specific examples.
First, the terminal accesses the base station for the first time
Referring to fig. 3, a flowchart illustrating a signaling tracking method according to a third embodiment of the present invention is shown. In this embodiment, the terminal is a terminal that accesses the base station for the first time, and the signaling tracking method includes:
step 302, acquiring the downlink rate of the terminal in a set time period or acquiring the IP address of the terminal.
Step 304, determining whether the terminal is a test terminal according to the downlink rate of the terminal in a set time period or the IP address of the terminal.
In this embodiment, if the downlink rate of the terminal in a set time period is greater than or equal to a set threshold, it indicates that the terminal processes a high-speed service for a long time, and is a test terminal. In addition, if the IP address of the terminal is consistent with the preset IP address of the test terminal, the terminal is determined to be the test terminal.
It should be noted that, after the terminal is accessed and has a service, it may be determined that the terminal is a test terminal according to the downlink rate of the terminal in a set time period, and meanwhile, a message is sent to the signaling high-level processing module to notify that the terminal is the test terminal, and the signaling high-level processing module records the IP address of the terminal.
In this embodiment, if the terminal is not a test terminal, the process may be directly ended, and if the terminal is a test terminal, the following step 306 may be continuously performed.
Step 306, recording the information such as the signaling service of the terminal in the base station.
Step 308, the state of the terminal is determined.
In a mobile environment, a terminal may change at any time, such as: the terminal is released, terminal reestablishment or terminal handover. In this embodiment, if the terminal is released, the process may be directly ended; if the terminal is reestablished, the following step 310 may be executed; if the terminal is handed over, the following step 312 may be performed.
Step 310, writing the tracking identifier into a private field or information element IE of the HANDOVER REQUEST message, and sending the HANDOVER REQUEST message carrying the tracking identifier to the reestablishing base station.

Wherein, the trace flag is used to indicate that the terminal is a test terminal, and the reestablishment REQUEST message may be, but is not limited to, a HANDOVER REQUEST message; the reestablishing base station may be a current base station (source base station) or other base stations, which is not limited in this embodiment.

In this embodiment, when the terminal performs S1 handover, the tracking identifier may be written in a corresponding handover request message and sent to the MME. Wherein the HANDOVER request message may be, but is not limited to, a HANDOVER request message.
For example, at the S1 handover, the transfer of the tracking identity may be realized by the iE-Extensions extension IE existing in SourceeNB-ToTargeteNB-Transparentcontainer in HANDOER REQUIRED. The extended IE (Source eNB-ToTargetNB-TranspartContainer) is not analyzed when being transmitted in the MME, only the source side and the target side are analyzed, and the Assigned Criticality of the iE-Extensions is set as the ignore, so that the base stations of different manufacturers can be ensured not to cause any problem due to the private IE in time.
Step 316, writing the tracking identifier into the private field or IE of the HANDOVER REQUEST message, and sending the HANDOVER REQUEST message carrying the tracking identifier to the opposite base station.
In this embodiment, when the terminal performs an X1 handover, the tracking identifier may be written in a corresponding handover request message and sent to the MME. Wherein, the HANDOVER REQUEST message may be, but not limited to, a HANDOVER REQUEST message.
For example, at X1 handover, the tracking identity is passed through iE-Extensions of UE-Contextinformation in HANDOER REQUEST.

Fifthly, when the terminal is reestablished to enter other base stations

In this embodiment, the terminal is a terminal that is re-established to another base station, that is, the base stations before and after re-establishment of the terminal are different base stations, and the signaling tracking method includes:

In this embodiment, the INDICATION message sent to the source base station may specifically be an RLF INDICATION message, which is used to indicate that the terminal has reestablished to enter another base station.
For example, when the terminal re-establishes into another base station, the source base station before re-establishment may be notified by the RLF INDICATION message, and the source base station may notify the context of the terminal and the flag bit (i.e., tracking id) of whether to perform tracking to another base station through iE-Extensions of UE-context information in the HANDOVER REQUEST message, so that the another base station that re-establishes access can continue to track signaling of the terminal.

In summary, in this embodiment, when the terminal is first accessed, whether the terminal is a test terminal may be directly determined according to the service or the IP address of the terminal, and when the terminal is switched to access or reestablishes access, whether the terminal is a test terminal may be directly determined according to the tracking identifier carried in the reestablishment request message or the handover request message, which reduces the interaction link with the core network side, reduces the communication cost, and has strong timeliness. Moreover, once the terminal is identified, whether the terminal is a test terminal can be quickly determined according to the request message in the subsequent moving process, so that the identification efficiency of the terminal is improved.
Secondly, even if the terminal is switched or reestablished, the base station can continuously track the terminal according to the reestablishment request message or the switching request message carrying the tracking identifier to acquire the signaling.
