In view of the problems in the related slicing techniques, the embodiments of the present invention consider to distinguish whether a finer-grained quality assurance mechanism (such as the distinguishing problem of different sessions, different apps, and the like, rates, delays, and access priorities) can be implemented in the same slice, and can be used for different quality assurance in the same slice by using methods such as the identity level in the user subscription information.
The embodiment of the invention further refines the quality assurance granularity in the same slice, performs further optimized splitting, and improves the user experience, and provides the following scheme:
example one
In this embodiment, in the same slice, the core network performs priority division of the terminal service through the APP ID. As shown in fig. 11, includes:
step 1101: the network adopts a Deep Neural Network (DNN) form to establish an initial slice;
step 1102: the terminal reports the APP ID when the PDU session is established;
here, the terminal reports a field of APP ID information when a protocol data unit session (PDU session) is established due to service triggering (APP ID is transmitted to the terminal communication module by the operating system when the APP is started, and the communication module transmits the APP ID to the core network).
Step 1103: and the core network carries out priority division according to the received APP ID.
Here, the APP ID information is transmitted to the core network by adding an indication bit information to PDU _ SESSION _ ESTABLISHMENT _ REQUEST (5GC AMF). And the AMF in the core network is sent to the SMF and other core network internal sub-network elements. And performing service transmission priority differentiation in the 5GC (determining corresponding recorded application program subscription information based on the APP ID; determining the transmission priority of the service of the terminal corresponding to the APP ID based on the application program subscription information). And the core network adjusts the data transmission flow proportion of the Ng port based on the priority division result, and improves the data transmission bandwidth of the user with the high-priority ADD ID.
Example two
In this embodiment, within the same slice, the base station side performs resource adjustment based on the priority sent by the core network.
The embodiment can be implemented on the basis of the first embodiment, and can also be implemented independently. After the network finishes the initial slicing and the terminal uploads the APP ID, the core network only makes a priority division suggestion according to the APP ID and informs the base station of the division result. The scheduling order of the actual physical resources is processed in the base station, the influence of the actual wireless environment of the user on the channel quality needs to be considered, and the core network only provides suggestions. The process is shown in fig. 12, and includes:
step 1201: the network adopts a Deep Neural Network (DNN) form to establish an initial slice;
step 1202: the terminal reports the APP ID when the PDU session is established;
step 1203: the core network carries out priority division according to the received APP ID;
step 1204: the core network informs the terminal priority corresponding to the APP ID to the base station;
step 1205: and the base station adjusts the scheduling priority and the resource allocation priority of the terminal based on the received terminal priority.
In the actual scheduling process:
when a base station determines that a high-priority terminal (user) suggested by a core network applies for an uplink service and the uplink channel quality X is greater than a threshold M (an empirical value can be modified), adjusting the scheduling priority of the user and increasing the scheduling resource amount according to the priority suggestion of the core network; otherwise, if the channel quality is less than or equal to the preset threshold, the base station processes according to a default scheduling algorithm.
When the base station determines that a high-priority terminal (user) suggested by a core network applies for downlink service and the downlink channel quality Y is greater than a threshold M, the base station adjusts the scheduling priority of the user and increases the scheduling resource amount according to the priority suggestion of the core network, otherwise, if the channel quality is less than or equal to a preset threshold, the base station processes according to a default scheduling algorithm.
In this embodiment, priority ranking may also be performed according to the resource amount of the service applied by the user, and the higher the applied resource amount is, the higher the priority ranking is.
EXAMPLE III
In this embodiment, the base station performs priority division according to the channel quality in the same slice.
After the terminal completes the establishment of the PDU session, the base station divides the terminal applying for the uplink service into A groups, divides the terminal applying for the downlink service into B groups, divides the terminal simultaneously applying for the uplink service and the downlink service into C groups, and divides the terminal not applying for the service into D groups.
In group a, the ordering is based on the uplink channel quality of the terminals (the priority ordering is denoted as UL _ SN). In group B, the ordering is performed according to the downlink channel quality of the terminal (the priority ordering is denoted as DL _ SN). In group C, sorting is carried out according to the difference value and the minimum value of the quality of the uplink and downlink channels of the terminal (the smaller the difference value of the quality of the uplink and downlink channels is, the quality of the uplink or downlink channel of the user is not less than the threshold N, and the priority sorting is high) (the priority sorting is expressed as DU _ SN). The resources for different groups of terminals are adjusted as follows:
group A: the base station adds UL _ SN of each user in UL _ NAS _ TRANSP signaling (the signaling carries PDU _ SESSION _ ESTABLISIFISH _ REQUEST message), the core network analyzes the information after receiving UL _ NAS _ TRANSP, priority sequencing of a terminal (user) for establishing a slice is obtained, flow adjustment of Ng ports is carried out based on the priority sequencing of the terminal, and Ng port uplink transmission bandwidth is correspondingly increased for the terminal with high priority;
group B: a base station adds DL _ SN of each user in UL _ NAS _ TRANSP signaling (the signaling carries PDU _ SESSION _ ESTABLISIFISH _ REQUEST message), a core network analyzes the information after receiving UL _ NAS _ TRANSP, obtains priority sequencing of a terminal (user) for establishing a slice, performs flow adjustment of Ng ports based on the priority sequencing of the terminal, and correspondingly increases downlink transmission bandwidth and downlink data volume of the Ng ports for the terminal with high priority;
group C: the base station adds DU _ SN of each user in UL _ NAS _ TRANSP signaling (the signaling carries PDU _ SESSION _ ESTABLISIFISH _ REQUEST message), the core network analyzes the information after receiving UL _ NAS _ TRANSP, obtains priority ranking of the terminal (user) establishing the slice, carries out flow adjustment of the Ng port based on the priority ranking of the terminal, and correspondingly increases uplink and downlink transmission bandwidth and downlink data volume of the Ng port for the terminal with high priority.
Similarly, in this embodiment, the base station may also perform priority ranking according to the resource amount of the service applied by the user, where the larger the applied resource amount is, the higher the priority ranking is.
Therefore, in the embodiment of the invention, the priority level classification is carried out on the terminal (service) in the same slice based on the information such as the APP ID, and/or the channel quality, and/or the resource amount of the service applied by the terminal (user), and the data transmission is adjusted based on the priority level classification result. Therefore, the user management in the same slice can be refined, resources are adjusted based on the priority level, and the management in the slice is more flexible; moreover, the service management can be strengthened by jointly managing the priority division and the resource adjustment through the core network and the base station.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
