All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort shall fall within the protection scope of the present application.
The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
As shown in fig. 1, this embodiment provides a Uu interface signaling association method, which includes the following steps:
acquiring a Uu interface message, wherein the Uu interface message comprises a reconfiguration message and a reconfiguration completion message;
decoding the reconfiguration message to obtain a first keyword, wherein the first keyword comprises a first base station identifier, a first cell wireless network temporary identifier, a first user equipment identifier and a first target cell wireless network temporary identifier;
decoding the reconfiguration completion message to obtain a second keyword, wherein the second keyword comprises a second base station identifier, a second cell wireless network temporary identifier, a second user equipment identifier and a second target cell wireless network temporary identifier;
and performing flow association according to the first keyword and the second keyword.
In this embodiment, the Uu interface message is obtained by a soft mining method, specifically, when the soft mining function of each network element (i.e., the gbb, 5G base station) is turned on, each network element outputs a data stream to other network elements from a monitor port on the device, and the data is aggregated by a traffic aggregation Adapter (SCA), and after adding a time identifier, the data is sent to a soft mining Signaling analysis device for subsequent processing such as decoding, association, and synthesis. The Uu interface switching signaling flow association and the like related to the scheme also belong to a key algorithm and an implementation link of a soft mining signaling analysis system.
As shown in fig. 2, in this embodiment, specifically, the Uu interface signaling association method includes the following steps:
s1, obtaining Uu interface information, wherein the Uu interface information comprises reconfiguration information and reconfiguration completion information;
in this embodiment, it can be understood that the reconfiguration message and the reconfiguration complete message include, but are not limited to, a chronological order of acquisition. For example, the reconfiguration message is acquired first, and then the reconfiguration complete message is acquired. In this embodiment, the Reconfiguration message is an RRC Reconfiguration message, and the Reconfiguration Complete message is an RRC Reconfiguration Complete message. Optionally, the Uu interface message may also include other messages besides the two, and the Uu interface message may be several messages.
S2, decoding the Uu interface message to obtain a keyword;
optionally, the method includes analyzing, by a signaling analysis device, the accessed soft mining Uu original code stream data according to a protocol type, including decoding each protocol stack data of the Uu interface, specifically including analyzing a general packet header and a special packet header of a Uu interface message, analyzing an upper RRC protocol and an NAS protocol, extracting a process-related keyword and service application field information, and finally filling, by a decoding module, all information fields obtained by decoding into a corresponding data structure.
Optionally, in this embodiment, the keywords include a message time, a gNB ID (base station identifier), a Cell ID (Cell identifier), a C-RNTI (Cell radio network temporary identifier), an AMF UE NGAP ID (i.e., user equipment identifier, which is a unique identifier of the UE in an NG interface allocated by the AMF, where the AMF is Access and Mobility Management Function, and the NG interface is an interface between a 5G base station and a 5G core network), a newUE-Identity (target C-RNTI, which is a target Cell radio network temporary identifier), a timer (in this embodiment, an intra-system handover T304 timer), a channeltype (message Channel Type), a C1 (homogeneous Channel message index), and the like.
The C-RNTI (Cell radio network Temporary Identifier) is a dynamic Identifier allocated to the UE by the base station, that is, the C-RNTI uniquely identifies the UE in a Cell gap.
Therefore, the first keyword obtained after decoding the reconfiguration message correspondingly includes a first message time, a first base station identifier, a first cell radio network temporary identifier, a first user equipment identifier, a first target cell radio network temporary identifier, a first timer, a first message channel type, and a first homogeneous channel message index. The second keyword obtained after decoding the reconfiguration complete message correspondingly comprises a second message time, a second base station identifier, a second cell radio network temporary identifier, a second user equipment identifier, a second target cell radio network temporary identifier, a second timer, a second message channel type and a second homogeneous channel message index.
In 5G systems, the gNB (base station) side users are usually distinguished by the cell radio network temporary identity C-RNTI resource, but since the C-RNTI is not unique in the whole network, the C-RNTI values of the users of different base stations may be the same, and the C-RNTI may also change if the UE is handed over to another cell. Therefore, different association methods need to be designed for association of the handover procedure and association of the rrc connection reconfiguration procedure.
S3, performing flow association according to the decoding result, specifically comprising the following steps:
s31, judging the type of the message;
and distinguishing the reconfiguration message from the reconfiguration completion message according to the message channel type and the similar channel message index.
For example, when Channel Type =3 (indicating DL-DCCH-MessageType) and the message of C1=0 indicates a Reconfiguration message (RRC Reconfiguration message);
when Channel Type =7 (indicating UL-DCCH-MessageType) and the message of C1=1 indicates a Reconfiguration Complete message (RRC Reconfiguration Complete message).
If the messages do not belong to the two messages, the messages are other messages.
Therefore, whether the Uu interface message is a reconfiguration message or a reconfiguration completion message can be judged by the method, and different processing associated flows are conveniently executed when the signaling analysis equipment processes the Uu interface message.
Referring to fig. 2, S32, the process-related flow is executed, and specifically includes the following steps:
s321, when the message type is reconfiguration message, determining whether the reconfiguration message contains a synchronization reconfiguration IE cell (reconfiguration WithSync cell);
1) If the synchronous reconfiguration IE information element is not included, it indicates that the reconfiguration message initiates a normal RRC reconfiguration signaling procedure (i.e., a RRC connection reconfiguration procedure), association of the RRC connection reconfiguration procedure is needed, a first processing procedure (including step A1 or A2) is executed, and it is determined whether the current message is a start message, specifically, when the current message is a reconfiguration message (and the reconfiguration message belongs to the start message), specifically:
a1, establishing a first XDR record by using the first base station identifier, the first cell identifier, and the first cell radio network temporary identifier as a first KEY value (first KEY), inserting the first XDR record into a first container (in this embodiment, a first MAP container), and waiting for a subsequent message to be associated.
And when judging that the message type is other messages, judging that the other messages do not belong to the starting message, and executing A2: and decoding the other messages to obtain corresponding third base station identification, third cell identification and third cell wireless network temporary identification as third correlation key values, searching and matching from the first container to correlate the wireless resource control connection reconfiguration flow, and if the searching and matching are successful, indicating that the signaling flow message correlation is successful. Optionally, the first container stores the first XDR record described above.
2) If the reconfiguration message contains the synchronous reconfiguration IE information element, the reconfiguration message is a message for carrying out synchronous reconfiguration from the source cell to the target cell, namely belongs to a switching process and needs to be associated with the switching process (a second processing process), and the association of the switching process comprises the following steps C-D:
C. confirming that the first user equipment identity has a numerical value (namely is not null), establishing a second XDR record by taking the first user equipment identity as a fourth KEY value (fourth KEY), and inserting and storing the second XDR record in a second container (in the embodiment, a second MAP container);
D. confirming that the first target cell radio network temporary identifier has a numerical value (i.e., is not empty), and establishing a third XDR record with the first target cell radio network temporary identifier as a fifth KEY value (fifth KEY) and inserting and storing the third XDR record in a third container (in this embodiment, a third MAP container).
Optionally, in this embodiment, each XDR record new insertion is stored in the container with a time value, including but not limited to a timestamp, e.g., the second XDR record corresponds to a first time value and the third XDR record corresponds to a second time value.
In this embodiment, after steps C and D, by acquiring the current time, the second XDR record corresponding to the difference between the current time and the first time value being greater than the value of the timer (T304) is cleared (i.e., output);
and clearing the third XDR record corresponding to the difference value between the current time and the second time value which is greater than the value of the timer (T304).
Through the processing, the XDR records of the second container and the third container with overtime association can be cleaned, so that the subsequent error association can be avoided, and the association accuracy is improved.
S322, determining whether the message type is a Reconfiguration Complete message (RRC Reconfiguration Complete message);
if yes, executing steps E-G (third processing flow):
E. first, the second base station identifier, the second cell identifier and the second cell radio network temporary identifier in the reconfiguration complete message are used as a second KEY value (second KEY), and the first container is searched and matched to associate the radio resource control connection reconfiguration process. If the matching is found successfully, it indicates that the process association is successful, and the session type is an RRC connection reconfiguration procedure (RRC connection reconfiguration process).
The message of the radio resource control connection reconfiguration process is not allocated to acquire the AMF UE NGAP ID value, so that association can only be performed by the method.
F. If the search for a match from the first container fails, it indicates that the current RRC Reconfiguration Complete message is likely to be a message of a handover procedure, and a search association needs to be performed in the second container or the third container that stores a handover XDR record (second XDR record or third XDR record):
confirming that the second ue identity has a numerical value (i.e. is not null), performing search matching from the second container with the second ue identity as a sixth KEY value (sixth KEY), if the search matching is successful, it represents that the association of the handover procedure is successful, for example, the second ue identity is equal to the first ue identity, then determining the first session type of the association of the handover procedure according to the first base station identity, the second base station identity, the first cell identity and the second cell identity, specifically:
confirming that the first base station identification is equal to the second base station identification, the first cell identification is equal to the second cell identification, and the first session type is intra-cell switching;
confirming that the first base station identification is equal to the second base station identification, the first cell identification is not equal to the second cell identification, and the first session type is intra-base station switching;
and confirming that the first base station identification is not equal to the second base station identification, wherein the first session type is the inter-base station switching.
As shown in fig. 3 (a), a Reconfiguration message (RRC Reconfiguration message) and a Reconfiguration Complete message (RRC Reconfiguration Complete message) for Uu interface RRC connection Reconfiguration procedure/intra-cell handover/intra-base station handover are shown in fig. 5G; fig. 3 (b) is a diagram illustrating a Reconfiguration message (RRC Reconfiguration message) and a Reconfiguration Complete message (RRC Reconfiguration Complete message) for inter-base station handover, where S-gbb represents a handover source base station and T-gbb represents a handover target base station.
G. If the search for a match from the second container fails, for example, the second user equipment identifier is not equal to the first user equipment identifier, the search for a match needs to continue to the third container:
and confirming that the second target cell radio network temporary identifier has a numerical value (namely, is not empty), searching and matching from the third container by taking the second target cell radio network temporary identifier as a seventh KEY value (seventh KEY), if the searching and matching are successful, for example, the second target cell radio network temporary identifier is equal to the first target cell radio network temporary identifier and represents that the association is successful, determining a second session type associated with the handover process, wherein the second session type comprises inter-base station handover which represents the handover process between base stations crossing the AMF.
Step G can implement the association of the handover procedure between the base stations across the AMF, because the AMF UE NGAP ID is allocated by the AMF and is the unique identifier of the UE in the NG interface, even if the handover is across the AMF, that is, when the AMF UE NGAP ID before and after the handover has changed, the association of the handover signaling procedure across the AMF can be implemented, which is different from the intra-base station handover in step F.
In conclusion, the scheme subdivides the Uu interface switching signaling flow and outputs fine analysis basic data, so that the association of intra-cell switching, intra-base station switching, inter-base station switching and radio resource control connection reconfiguration flow can be effectively realized, the comprehensive association of the Uu interface signaling flow, particularly the switching signaling flow is realized, the accuracy and the integrity of the association of the switching signaling flow are greatly improved, and the scheme is simple and efficient.
