Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
One of the core concepts of the embodiments of the present invention is that, by receiving a measurement report reported by a user equipment, and determining an operation instruction and an adjacent cell according to the measurement report, before performing a processing operation corresponding to the operation instruction, it needs to determine whether network slice information supported by an adjacent base station corresponding to the adjacent cell matches allowed network slice information of the user equipment, and perform the processing operation corresponding to the operation instruction on the matched adjacent cell, so as to ensure PDU session establishment of the user equipment and improve user experience.
Referring to fig. 1, a flowchart illustrating a first step of a method for processing network slice information of user equipment between base stations according to a first embodiment of the present invention may specifically include the following steps:
in the moving process of the user equipment, the user equipment needs to send a measurement report to the cell of the source base station according to the measurement configuration indication of the source base station. The user equipment may be a device capable of transmitting or receiving wireless signals, such as a mobile phone, a Personal Digital Assistant (PDA), a wireless modem, a smart appliance, or other devices capable of autonomously communicating with the mobile communication network without human operation. The source base station cell refers to a current service cell of the user equipment, and a base station to which the source base station cell belongs is a source base station. The measurement report is a measurement made by the user equipment that may include the current serving cell and neighbor cells.
the measurement report includes a Physical Cell Identifier (PCI), a measurement Identifier (meas ID), and the like. Determining an operation instruction corresponding to the measurement report according to the measurement identifier in the measurement report; and determining a frequency point of a corresponding measurement Object identifier (Meas Object Id) according to the measurement identifier in the measurement report, and determining a neighboring cell by adopting the physical cell identifier and the frequency point. The operation instruction comprises a switching operation, an adding operation and the like, wherein the switching operation generally refers to switching of a Long Term Evolution (LTE) system, so that the user equipment is enabled to change a current service cell; the addition operation generally refers to adding a secondary base station of the source base station in a dual connection scenario. The adjacent cells comprise inter-station adjacent cells and intra-station adjacent cells, base stations to which the inter-station adjacent cells belong are different from the source base station, and the base stations to which the intra-station adjacent cells belong are the same as the source base station.
the source base station may instruct the ue to acquire network slice information (NSSAI) supported by a neighboring base station corresponding to the neighboring cell, and match the acquired network slice information supported by the neighboring base station with Allowed network slice information (Allowed NSSAI) of the ue. When the adjacent cell is the intra-cell adjacent cell, the corresponding adjacent base station is the source base station, the network slice information supported by the source base station is matched with the network slice information allowed by the user equipment, and in order to reduce resource waste, when the adjacent cell is the intra-cell adjacent cell, the adjacent base station corresponding to the adjacent base station, that is, whether the network slice information supported by the source base station is matched with the allowed network slice information for the equipment, does not need to be judged. When the neighboring cell is an inter-station neighboring cell, the corresponding neighboring base station is different from the source base station, and therefore, the network slice information supported by the neighboring cell needs to be matched with the network slice information allowed by the user equipment.
And 104, if yes, executing processing operation corresponding to the operation instruction to the adjacent cell.
And when the network slice information supported by the adjacent base station corresponding to the adjacent cell is matched with the allowed network slice information of the user equipment, executing corresponding processing operation on the adjacent cell according to the operation instruction determined in the step 102.
And when the network slice information supported by the adjacent base station corresponding to the adjacent cell is not matched with the allowed network slice information of the user equipment, the operation indicates that the corresponding processing operation flow is ended, and the corresponding processing operation is failed.
In the embodiment of the invention, the source base station cell receives the measurement report reported by the user equipment, determines the operation instruction and the adjacent cell according to the measurement report, and executes the processing operation corresponding to the operation instruction on the matched adjacent cell by judging whether the network slice information supported by the adjacent base station corresponding to the adjacent cell is matched with the allowed network slice information of the user equipment, so that the network slice information supported by the adjacent cell executing the processing operation corresponding to the operation instruction is matched with the allowed network slice information of the user equipment, the PDU session establishment of the user equipment is ensured, and the user experience is further improved.
Referring to fig. 2, a flowchart illustrating a second step of the method for processing network slice information of user equipment between base stations according to the embodiment of the present invention is shown, which specifically includes the following steps:
and the user equipment reports the measurement report to the cell of the source base station according to the measurement configuration indication of the source base station. Please refer to the description of step 101.
in this embodiment, the step of determining an operation instruction and a neighboring cell according to the measurement report includes the following sub-steps:
The measurement report comprises information such as physical cell identification and measurement identification, and the source base station cell obtains the physical cell identification and the measurement identification in the measurement report by analyzing the measurement report reported by the user equipment. The parameters of the cell generally comprise frequency points, physical cell identifiers and the like, the frequency points can be indicated by measurement object identifiers, and each measurement identifier corresponds to one measurement object identifier and one report configuration; multiple measurement identifiers may also correspond to the same report configuration; therefore, by using the measurement identifier obtained from the measurement report, the corresponding measurement object identifier and report configuration can be determined, and then the frequency point of the measurement object identifier can be determined, the operation instruction of the measurement report can be determined according to the report configuration, and the adjacent cell can be determined according to the frequency point and the physical cell identifier. In the second embodiment of the present invention, the operation indication is a handover operation, that is, a measurement report reported by the ue is a measurement report for handover.
the neighbor cell determined according to the measurement report may only have intra-station neighbor cells, may only have inter-station neighbor cells, or may have both intra-station neighbor cells and inter-station neighbor cells. Because the base station to which the adjacent cell in the station belongs is the same as the source base station, the base station to which the adjacent cell in the station belongs is different from the source base station. Therefore, whether the adjacent cell has the inter-station adjacent cell can be judged by judging whether the base station to which the adjacent cell belongs is the same as the source base station in the adjacent cell relation table, if the base station of the adjacent cell is different from the source base station, the corresponding adjacent cell is the inter-station adjacent cell, otherwise, if the base station of the adjacent cell is the same as the original base station, the corresponding adjacent cell is the intra-station adjacent cell.
And 204, if the network slice information exists, judging whether the network slice information supported by the inter-station adjacent base station corresponding to the inter-station adjacent cell is matched with the allowed network slice information of the user equipment.
If the adjacent cell exists between the stations, the network slice information supported by the adjacent base station between the stations corresponding to the adjacent cell between the stations needs to be acquired. The source base station may instruct the user equipment to obtain network slice information supported by the inter-station neighboring base station corresponding to the inter-station neighboring cell, and feed back the network slice information to the source base station. And the source base station judges whether the network slice information supported by the inter-station adjacent base station is matched with the allowed network slice information of the user equipment.
If the adjacent cell does not have the inter-station adjacent cell, the adjacent cell is an intra-station adjacent cell, the intra-station adjacent cell corresponds to the source base station, and it can be considered that the network slice information supported by the base station in the intra-station adjacent cell is matched with the allowed network slice information of the user equipment, and the next step can be directly performed.
the target neighbor cell is the optimal neighbor cell in the neighbor cells with successful handover preparation, and the network slice information supported by the base station to which the target neighbor cell belongs is matched with the allowed network slice information of the user equipment.
Specifically, when an inter-station neighboring cell exists in a neighboring cell, the source base station cell sends a Handover Request (Handover Request) to the inter-station neighboring base station matched with the allowed network slice information of the user equipment, and receives a response message (Handover Request ACK) of the corresponding Handover Request, which indicates that the inter-station neighboring base station is successfully prepared, i.e., that the inter-station neighboring cell corresponding to the inter-station neighboring base station is successfully prepared.
When the adjacent cell exists in the station, the source base station cell confirms that the switching preparation of the station adjacent cell is successful through the internal interface message of the source base station.
And determining the optimal neighbor cell in the neighbor cells with successful handover preparation according to the measurement report, wherein the optimal neighbor cell can be the neighbor cell with strongest communication signal strength and/or most stable signal strength in the neighbor cells with successful handover preparation.
In the embodiment of the invention, a source base station cell receives a measurement report reported by user equipment, obtains a physical cell identifier and a measurement identifier in the measurement report, and determines a frequency point and an operation instruction of a corresponding measurement object identifier as switching operation by adopting the measurement identifier; determining a neighbor cell by adopting a physical cell identifier and a frequency point; judging whether an inter-station adjacent cell exists in an adjacent cell, matching network slice information supported by an inter-station adjacent base station corresponding to the inter-station adjacent cell with allowed network slice information of user equipment, sending a switching request to the successfully matched inter-station adjacent base station, if a response message of the corresponding switching request is received, indicating that the switching preparation of the inter-station adjacent cell corresponding to the inter-station adjacent base station is successful, and confirming that the switching preparation of the intra-station adjacent cell is successful for the intra-station adjacent cell through an internal interface cell of a source base station; and then, determining the optimal neighbor cell as a target neighbor cell from the neighbor cells with successful switching preparation, sending a switching command to the user equipment, and switching the user equipment to the target neighbor cell according to the switching command, namely executing the switching operation corresponding to the switching operation command, ensuring the PDU session establishment of the user equipment, and further improving the user experience.
Referring to fig. 3, a flowchart illustrating a third step of a method for processing network slice information of user equipment between base stations according to a third embodiment of the present invention is shown.
In the dual-connection scenario, wireless resources of two cells or base stations are concentrated to provide services for the user equipment, that is, the user equipment is connected with the two cells or base stations, one of the base stations is connected to an AMF (Access and Mobility Management Function) through an NG interface, the NG interface is an interface between a wireless Access network and a 5G core network, that is, the base station directly connected with the 5G core network is a main base station; the other base station connected with the main base station through an Xn interface is a secondary base station, and the Xn interface is a connection interface between gNB base stations (5G base stations). In a dual connectivity scenario, each base station can independently manage the user equipment and the radio resources in its respective cell.
The method may specifically comprise the steps of:
and the user equipment reports the measurement report to the cell of the source base station according to the measurement configuration indication of the source base station. The measurement report is a report of the user equipment measuring the neighbor cell. .
in this embodiment, the step of determining an operation instruction and a neighboring cell according to the measurement report includes the following sub-steps:
a substep 3022, determining the frequency point of the corresponding measurement object identifier and the operation instruction by using the measurement identifier;
and a substep 3023, determining the neighboring cell by using the physical cell identifier and the frequency point.
And the source base station cell acquires the physical cell identifier and the measurement identifier in the measurement report by analyzing the measurement report reported by the user equipment. By adopting the measurement identifier obtained from the measurement report, the corresponding measurement object identifier and report configuration can be determined, the frequency point of the measurement object identifier can be further determined, the operation instruction of the measurement report can be determined according to the report configuration, and the adjacent cell can be determined according to the frequency point and the physical cell identifier. In the third embodiment of the present invention, the operation indication is an addition operation, that is, a measurement report reported by the user equipment is a measurement report for adding the secondary base station node. In this embodiment, the source base station is a master base station, and the adjacent cells only include inter-station adjacent cells.
and determining whether the neighbor cell allows sending of a secondary base station NODE ADDITION REQUEST (S-NODE ADDITION REQUEST) by matching the network slice information supported by the neighbor base station corresponding to the neighbor cell with the allowed network slice information of the user equipment. Specifically, if the network slice information supported by the neighboring base station corresponding to the neighboring cell matches the allowed network slice information of the user equipment, it indicates that the neighboring cell allows sending the auxiliary base station node addition request; otherwise, it indicates that the neighboring cell does not allow sending the auxiliary base station node addition request, and at this time, the flow corresponding to the addition operation is ended and the addition fails.
the allowable transfer of network slice information is added to the secondary base station NODE ADDITION REQUEST (S-NODE ADDITION REQUEST) message in the 38.423 protocol to ensure the perception of the ue after subsequent secondary base station ADDITION and modification.
Preferably, after receiving the auxiliary base station node addition request message, the neighboring base station stores the allowed network slice information of the user equipment in the auxiliary node addition request message. So that when the neighboring base station needs to use the allowed network slice information of the user equipment at a later stage, the neighboring base station can directly extract the stored information, thereby simplifying the step of obtaining the allowed network slice information of the user equipment at the later stage.
and when a response message of the adjacent base station to the auxiliary base station node adding request message is received, indicating that the preparation of adding the auxiliary base station node by the adjacent base station is successful.
And sending a secondary base station node adding command, namely a reconfiguration message of an air interface, to the user equipment, so that the user equipment adds the adjacent base station as the secondary base station of the user equipment, namely, executes an adding operation corresponding to the adding operation command, and after the adding is successful, the user equipment can access the cell of the secondary base station to complete the configuration of dual connectivity. In a dual connectivity scenario, there are two cells serving user equipment simultaneously, one of which is a cell of a primary base station and the other is a cell of a secondary base station.
In the embodiment of the invention, in a dual-connection scene, a source base station cell receives a measurement report reported by user equipment, obtains a physical cell identifier and a measurement identifier in the measurement report, and determines a frequency point and an operation instruction of a corresponding measurement object identifier as an adding operation by adopting the measurement identifier; determining a neighbor cell by adopting a physical cell identifier and a frequency point; the method comprises the steps that network slice information supported by an adjacent base station corresponding to an adjacent cell is matched with allowed network slice information of user equipment, an auxiliary base station node adding request is sent to the adjacent base station which is successfully matched, when corresponding information of the auxiliary base station node adding request information of the adjacent base station is received, an auxiliary base station node adding command is sent to the user equipment, and the user equipment adds the adjacent base station as an auxiliary base station of the user equipment according to the auxiliary base station node adding command. When the auxiliary base station is added, the network slice information supported by the added auxiliary base station needs to be matched according to the allowed network slice information of the user equipment, so that the network slice information supported by the added auxiliary base station is matched with the allowed network slice information of the user equipment, the PDU session establishment of the user equipment is further ensured, and the user experience is improved.
As shown in fig. 4, further, in the method for inter-base station user equipment network slice information processing, the method further includes:
the secondary base station cell is used for receiving a measurement report reported by the user equipment; determining the corresponding operation instruction as modification operation and determining the adjacent cell of the auxiliary base station according to the measurement report; the specific implementation method for determining the corresponding operation instruction and the secondary base station neighboring cell according to the measurement report is similar to the step 302, and reference may be made to the description of the step 302; judging whether network slice information supported by an auxiliary base station adjacent cell corresponding to the auxiliary base station adjacent cell is matched with allowed network slice information of the user equipment; and determining a target secondary base station from the successfully matched secondary base station neighbor base stations. It can be appreciated that the network slice information supported by the target secondary base station matches the allowed network slice information of the user equipment. In a specific implementation, the secondary base station may perform matching judgment on pre-stored allowed network slice information of the user equipment and network slice information supported by a neighboring base station of the secondary base station. Preferably, when there are a plurality of successfully matched secondary base station neighbor base stations, the secondary base station neighbor base station with the strongest communication signal strength and/or the most stable signal strength may be determined as the target secondary base station according to the measurement report.
The secondary base station cell sends a secondary base station modification request message (S-NODE CHANGE request) including a target secondary base station identifier (SgNB ID) to the source base station cell, where in this embodiment, the source base station cell is a main base station cell in a dual connectivity scenario. The secondary base station modification request message aims to take the target secondary base station as the secondary base station and replace the secondary base station which currently sends the secondary base station modification request message.
each base station has a corresponding identifier, i.e. the identifier of the target secondary base station corresponds to the target secondary base station. The source base station receives the auxiliary base station modification request message containing the target auxiliary base station identification, the target auxiliary base station identification can be obtained by analyzing the auxiliary base station modification request message, and the only target auxiliary base station corresponding to the target auxiliary base station identification can be determined through the target auxiliary base station identification.
and the auxiliary base station node addition request message contains the allowed network slice information of the user equipment.
Preferably, after receiving the auxiliary base station node addition request message, the target auxiliary base station stores the allowed network slice information of the user equipment in the auxiliary node addition request message. And when the measurement report uploaded by the user equipment and used for modifying the auxiliary base station is received at a later period, whether the network slice information supported by the adjacent base station of the target auxiliary base station is matched can be judged through the stored allowed network slice information of the user equipment.
and when a response message of the target secondary base station to the secondary base station node addition request message is received, indicating that the secondary base station addition preparation is successful.
And sending a secondary base station node adding command, namely a reconfiguration message of an air interface, to the user equipment. After receiving an auxiliary base station node adding command, the user equipment replaces an auxiliary base station with a target auxiliary base station, wherein the auxiliary base station is an original auxiliary base station, and the target auxiliary base station is added as a new auxiliary base station of the user equipment; namely, in the dual connectivity scenario, the operation of modifying the secondary base station is performed. In this case, there are two cells serving the user equipment simultaneously, one of which is the cell of the primary base station and the other of which is the cell of the target secondary base station.
Further, in the method for processing network slice information of user equipment between base stations, the method further includes:
