For the purpose of facilitating an understanding of the embodiments of the present application, reference will now be made to the following description of specific embodiments, taken in conjunction with the accompanying drawings, which are not intended to limit the embodiments of the application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an application scenario provided in an embodiment of the present application. The application scenario provided in this embodiment includes: terminal 100, base station 200, and core network 300, terminal 100 is connected to core network 300 via base station 200. The terminal 100 is configured to send a session request to the base station 200, where the base station 200 is configured to receive the session request sent by the terminal 100 after determining that the base station 200 is in the first state; determining an established protocol data unit PDU session set; determining a first PDU session from a set of PDU sessions; selecting a target bearer from a bearer set contained in the first PDU session according to a preset rule; wherein the target bearer is characterized as a bearer other than the default bearer; and obtaining a second PDU session corresponding to the session request according to the target bearer. The core network 300 is used for the base station 200 to perform data interaction with the base station 200 after determining the target bearer, so as to establish a second PDU session between the terminal 100, the base station 200 and the core network 300, or modify the second PDU session between the terminal 100, the base station 200 and the core network 300.
Referring to fig. 2, a flow chart of a data processing method according to an embodiment of the application is shown in fig. 2. The data processing method provided by the embodiment of the application is applied to a base station side and comprises the following steps:
s10: and after the base station is in the first state, receiving a session request sent by the terminal.
The base station is in a first state, which means that the base station is in a congestion state, namely, no available bearing is available at the base station side. The session request is used to indicate the establishment of a PDU session or the modification of a PDU session. When the base station side has no available bearer, the base station may need to reject the session request after receiving the session request sent by the terminal, or preempting other bearers to accommodate the session request, so as to solve the congestion state of the base station, thereby ensuring the stability and security of the whole 5G communication system.
S20: an established set of protocol data unit PDU sessions is determined.
Wherein the set of established protocol data unit PDU sessions includes a plurality of PDU sessions, each PDU session includes at least one bearer, and there is a default bearer in the at least one bearer, each bearer includes at least one quality of service QoS flow.
S30: a first PDU session is determined from the set of PDU sessions.
In this embodiment, in order to improve the use experience of the end user, the congestion state of the base station is processed by preempting other bearers to accommodate the session request instead of adopting a manner of rejecting the session request. Since each established session contains at least one bearer, the method of determining the PDU session is first determined in this embodiment to determine the bearer to be preempted. The session request carries session priority information, where the session priority information is the first priority of the PDU session to be established or the first priority of the PDU session to be modified, and the congestion state of the base station can be solved by preempting the bearer included in the low priority session (the determined priority of the session is lower than the priority of the PDU session to be established or the determined priority of the session is lower than the priority of the PDU session to be modified). In this embodiment, the determining the first PDU session from the PDU session set includes:
determining a second priority relation corresponding to the PDU session set;
a first PDU session is determined from the set of PDU sessions based on the session priority information and the second priority relationship.
Each session in the PDU session set has priority, and all sessions in the PDU session set can be ordered according to the order of the priority from high to low to obtain a second priority relation; all the sessions in the PDU session set can be sequenced according to the sequence from low priority to high priority, so as to obtain a second priority relation, and the priorities in the specific second priority relation can be sequenced according to actual needs. After the session priority information and the second priority relation are acquired, comparing the priority contained in the session priority information with the second priority relation, determining a second priority lower than the first priority from the second priority relation, and determining a PDU session corresponding to the second priority from the PDU session set when only one second priority exists; when there are a plurality of second priorities, one second priority may be randomly selected from the plurality of second priorities, or a second priority with the lowest priority may be selected from the plurality of second priorities, and then a PDU session corresponding to the second priority is determined from the PDU session set. In this embodiment, when there are a plurality of second priorities, the selection of the second priorities may be specifically performed according to actual needs, which is not specifically limited in this embodiment.
S40: selecting a target bearer from a bearer set contained in the first PDU session according to a preset rule; wherein the target bearer is characterized as a bearer other than the default bearer.
In this embodiment, in order to avoid that the preempted bearer is a default bearer and the end user releasing the default bearer affects the use experience of the end user, bearers other than the default bearer are selected from the determined bearer set of the first PDU session according to a preset rule, so as to preempt the selected bearer, thereby improving the use experience of the end user.
The target bearer in step S40 may be selected as follows:
for each bearer in a bearer set contained in the first PDU session, determining carrying information of a QoS flow contained in the bearer, and obtaining a carrying information set corresponding to the bearer set;
and selecting a target bearer from the bearer set contained in the first PDU session according to the carrying information set and the identification information.
In this embodiment, the carrying information in the QoS flow includes a plurality of QoS parameter information, for example, the parameter information includes an identifier of a default bearer, an identifier of additional information of the QoS flow, and an identifier of the QoS flow included in the default bearer. The identification information is prestored in a base station side, when the base station is determined to be in a congestion state, and when a session request sent by a terminal is received, the carried information set is compared with the identification information, so that a target bearing is selected from the bearing set contained in the determined first PDU session.
In one embodiment, referring to fig. 3, selecting a target bearer from a set of bearers included in a first PDU session may be accomplished by:
s411: when the identification information comprises a first identification, determining first carrying information meeting a first preset condition from a carrying information set; the first preset condition is that the first carrying information does not contain a first identifier, and the first identifier is used for identifying a default bearing;
s412: selecting a first bearer corresponding to the first carried information from the bearer set;
s413: the first bearer is determined to be the target bearer.
Wherein the first identification is default QoS rule indication (default QoS rule identification, DRQ) field. The core network side of the 5G communication system is provided with a set of default bearer identification mechanism, namely the core network side identifies the carrying information of the QoS flow through default QoS rule, and when the carrying information contains a DRQ field, the bearer corresponding to the QoS flow can be judged to be the default bearer. In this embodiment, an NG port is added between the base station side and the core network side, and the core network side sends the identified DRQ field to the base station side for pre-storage through the NG port. When the base station side needs to preempt the bearer, the base station judges each piece of carrying information in the carrying information set through the DRQ field, and when the carrying information does not contain the DRQ field, the bearer corresponding to the QoS flow containing the carrying information is characterized as the default bearer; when the carrying information includes the DRQ field, the bearer corresponding to the QoS flow including the carrying information is characterized as not being a default bearer (i.e., a bearer other than the default bearer). When the default bearer and the bearers other than the default bearer are judged according to the DRQ field, the bearers other than the default bearer are preempted to obtain a second PDU session corresponding to the session request according to the session request (i.e. the second PDU session is established or modified). In this embodiment, the first identifier sent by the core network is received to identify the default bearer for the carried information, so that the consistency of identifying the default bearer by the core network side and the base station side is ensured.
In another embodiment, referring to fig. 4, selecting the target bearer from the set of bearers included in the first PDU session may also be implemented by:
s421: when the identification information comprises a second identification, aiming at each piece of carrying information in the carrying information set, judging whether the carrying information comprises the second identification or not to obtain a judging result, and obtaining a judging result set corresponding to the carrying information set; wherein the second identifier is used for identifying additional information of the QoS flow;
s422: determining a first priority relation corresponding to the bearing set;
s423: determining a default bearer from the bearer set according to the judging result set and the first priority relation;
s424: and selecting bearers except the default bearer from the bearer set to determine the bearer as a target bearer.
In this embodiment, the second identifier is pre-stored in the base station, the second identifier is a Additional QoS Flow Information (additional information of QoS flow) field, and the additional information of QoS flow is characterized in that QoS flow needs to be established more frequently, that is, when the carrying information of QoS flow includes a Additional QoS Flow Information field, the QoS flow needs to be established more frequently than other QoS flows in the same PDU session; and when the carried information of the QoS flow does not contain Additional QoS Flow Information field, the QoS flow does not need to be established more frequently. Because the second identifier may be included in the carrying information in the QoS flows included in the plurality of bearers in the first PDU session, or the second identifier may not be included in the carrying information in the QoS flows included in the bearers, after the judging result of the carrying information and the second identifier is obtained, the default bearer and the bearers except the default bearer are determined according to the first priority relation corresponding to the bearer set. The judging result comprises yes judging result and no judging result, wherein the judging result is that the characterization carried information contains the second mark, and the judging result is that the characterization carried information does not contain the second mark. Each bearer in the bearer set contained in the first PDU session has priority, and all bearers in the bearer set can be ordered according to the order of the priority from high to low to obtain a first priority relation; all the bearers in the bearer set can be ordered according to the order of the priorities from low to high to obtain a first priority relation, and the priorities in the specific first priority relation can be ordered according to actual needs.
In this embodiment, the default bearer may be determined from the bearer set according to the judging result set and the first priority relationship by:
when all the judging results in the judging result set are negative, determining a second bearing corresponding to the highest priority in the bearing set as a target bearing;
when only one judging result exists in the judging result set, determining a third bearing corresponding to the judging result in the bearing set as a target bearing;
when a plurality of judging results exist in the judging result set, determining each fourth bearing corresponding to the judging result from the bearing set;
and determining the fourth bearer corresponding to the highest priority in the fourth bearers as a target bearer.
In this embodiment, it should be noted that, since at most one default bearer exists in each established PDU session, when there are multiple judging results in the judging result set, multiple fourth bearers which are yes with the judging results are obtained, and the first priority relation of the bearer set is combined to determine the default bearer in the established PDU session.
In yet another embodiment, referring to fig. 5, selecting a target bearer from the set of bearers included in the first PDU session may also be implemented by:
s431: when the identification information comprises a third identification set, determining second carrying information meeting second preset conditions from the carrying information set; the second preset condition is that the second carrying information fails to match with a third identifier set, and each third identifier in the third identifier set is used for identifying the contained QoS flow of the default bearer;
s432: selecting a fifth bearer corresponding to the second carrying information from the bearer set;
s433: the fifth bearer is determined as the target bearer.
In this embodiment, the third identifier set is pre-stored in the base station, where the third identifier set may be configured by a network management device, and the configured third identifier set is sent to the base station side for pre-storage through the core network. The third set of identifiers is a list of 5QI (identifiers of QoS flows contained in the default bearer). After the carried information set is obtained, each carried information in the carried information set is matched with a third identifier set, and after the matching is successful, the carried information corresponding to the successful matching is characterized as including one third identifier in the third identifier set, namely, the bearer corresponding to the QoS flow including the carried information is a default bearer; and after the matching fails, characterizing that any one of the third identifiers in the third identifier set is not contained in the carrying information corresponding to the matching failure, namely, the bearer corresponding to the QoS flow containing the carrying information is a bearer except the default bearer. And determining a default bearing and a bearing except the default bearing from the bearing set according to the matching result of each piece of carrying information in the carrying information set and the third identification set, so that when the bearing needs to be preempted, the bearing except the default bearing is selected according to the matching result.
S50: and obtaining a second PDU session corresponding to the session request according to the target bearer.
After selecting the target bearer, the base station processes the session request and performs data interaction with the core network to establish a second PDU session or modify the second PDU session.
