Description
Technical Field
The present invention relates to data processing technologies, and in particular, to a method and an apparatus for processing a conflict in a 5G system.
Background
In the 5G system, due to different implementation algorithms or different starting points of processing events, some intelligent units may cause conflicts in output analysis results or provided decisions when providing services for the same object. In this case, the served object receives at least two different decisions from different intelligent units, and cannot determine which decision to execute, resulting in system crash. For example, the NWDAF notifies the AMF network element that the current network performance is good, the access control mechanism operates well, and more users can be accessed. But at the same time, the MDAF informs the AMF network element that the user experience is not good, and needs to strictly control the user access or consider transferring a part of users to other cells. The AMF will not be able to smoothly perform the access control mechanism due to the different analysis results or policies provided by different intelligent units.
In the prior art, for resource type conflicts in the wireless field, the base station is generally used for scheduling to resolve the resource conflicts or avoid the conflicts. But there is no base station-like entity in the 5G system that can effectively resolve or coordinate the conflict of multiple intelligent units. Besides resources, the conflicting fields may also include aspects such as network configuration, performance index, quality of experience analysis, and the like, and the conventional base station cannot solve the problems in these fields.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a collision processing method in a 5G system according to an embodiment of the present invention, where the method shown in fig. 1 is applied to a functional unit or a network element in the 5G system. Referring to fig. 1, the method may include:
step 101: receiving at least two different service data from different intelligent units, wherein the at least two different service data are service data aiming at the same event processing or the same configuration parameter.
The intelligent unit can be an existing intelligent unit in the 5G system or an intelligent unit which may appear in the future, and the intelligent unit can be a unit which processes data by using an artificial intelligence technology and is defined in the 5G system and has an intelligent function. Examples include, but are not limited to, 3GPP defined NWDAF (network Data analysis Function), MDAF (Management Data Function), O-RAN defined RIC (Radio intelligent control), and the like. The service data may be the analysis results of the intelligent units or policy data.
Step 102: priority configuration information or conflict suggestion information is obtained.
The acquisition of the priority configuration information has different implementation manners, and may be configured based on signaling, or may be configured in advance in a functional unit or a network element, for example.
Step 103: determining first data from the at least two different service data based on the priority configuration information or the conflict suggestion information.
The priority configuration information specifies the service data to be prioritized according to what criteria, wherein a first data can be determined from the at least two service data, and the associated operation can be subsequently performed according to the determined first data.
Step 104: and executing corresponding operation according to the first data.
After the first data is determined, corresponding operations may be performed according to the first data without having to face at least two service data any more, and without knowing a scenario of which service data is employed.
In the conflict processing method in the 5G system described in this embodiment, after the functional unit or the network element receives different service data for the same event process or the same configuration parameter, a service data may be determined from at least two service data according to the priority configuration information, and corresponding operation is performed according to the determined service data, so that a situation that a system is crashed due to which service data is not known to perform related operation when different service data are faced is avoided, and normal operation of the 5G system is ensured.
In the above embodiments, the obtaining of the priority configuration information or the conflict suggestion information has different implementations. For example, in one implementation, the obtaining priority configuration information or conflict suggestion information may include: receiving priority signaling and acquiring priority configuration information from the priority signaling. In another implementation, the obtaining of the priority configuration information or the conflict suggestion information may include: and acquiring priority configuration information from preset priority data.
In yet another implementation, the obtaining of the priority configuration information or the conflict suggestion information may include: reporting a conflict event to a conflict management network element, wherein the conflict event is the reception of at least two different service data from different intelligent units; and receiving conflict suggestion information which is sent by the conflict management network element and determined according to the pre-configured priority configuration information.
For example, in one specific implementation, one network element in the 5G system is a PCF, and the intelligent unit includes an NWDAF and an MADF; a network function or network element COHF is newly defined for resolving conflicts between intelligent unit analysis results/decisions. Fig. 2 is a timing diagram of a collision processing method disclosed in an embodiment of the present invention, and referring to fig. 2, when a network element PCF receives QoS parameter configuration information sent from an NWDAF and an MADF, respectively, and the QoS parameter configuration information sent by the NWDAF and the MADF are different, the PCF reports the collision information to a COHF, and the COHF may analyze the collision information according to built-in priority configuration information, and then returns a result obtained by the analysis to the PCF as simple information.
In the above embodiment, the priority configuration information may be configured according to any one of the following standards: the intelligent unit for sending the service data is positioned in the system, the sending time or receiving time of the service data and a fixed rule; the priority configuration information realized according to different standards corresponds to different priority configuration strategies.
Fig. 3 is a schematic diagram of a priority configuration policy implementation according to an embodiment of the present invention, and in one implementation, with reference to fig. 3, for a PCF, a conflict is generated due to different QoS parameter configurations recommended by an MDAF and an NWDAF. The MDAF is an intelligent unit at the gateway level and therefore has a higher priority than the NWDAF at the core network level, so the PCF can accept the QoS parameter configuration recommended by the MADF, setting the delay to "< 5 ms". The realization has the advantages of being beneficial to network management and simple. Wherein the priority order (analysis result of MDAF or policy over NWDAF) may be configured to PCF through signaling or set in advance in PCF.
Fig. 4 is a schematic diagram illustrating a second implementation of a priority configuration policy according to an embodiment of the present invention, and referring to fig. 4, in this implementation, conflicts occur between QoS parameter configurations recommended by PCF, MDAF, and NWDAF. Since the time T1 when the MDAF recommends the QoS parameter is earlier than the time T2 when the NWDAF recommends the QoS parameter, the PCF accepts the MADF recommended QoS parameter configuration, setting the delay to "< 5 ms". The realization has the advantages of being more beneficial to network management and simple.
Fig. 5 is a schematic diagram illustrating a third implementation of a priority configuration policy disclosed in an embodiment of the present invention, and referring to fig. 5, in this implementation, conflicts are generated for different QoS parameter configurations recommended by PCF, MDAF, and NWDAF. The PCF sets the delay according to different functions, e.g. a minimum function, a maximum function or an average function. The advantage of this implementation is simplicity.
Fig. 6 is a schematic diagram illustrating implementation of a fourth priority configuration policy disclosed in the embodiment of the present invention, and in combination with fig. 6, different network functions or network elements and conflict policy configurations may be different. In fig. 6, for PCF, the collision mechanism is based on the time at which the analysis/decision data is sent; for SMF, the collision mechanism is based on the location of the intelligent network element sending the analysis/decision data; for OAM, the collision mechanism is function based. The advantages of this implementation are flexibility with optimal performance.
