Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The service quality policy processing method provided by the embodiment of the application can be applied to an application environment shown in figure 1. Wherein, the network elements of the visiting place can include session management function network elements (Session Management Function, SMF), mobility management entity network elements (Mobile MANAGEMENT ENTITY, MME)), mobility management function network elements (ACCESS AND Mobility management Function, AMF), user plane function network elements (User Plane Function, UPF); the home network elements may include Unified data management function network elements (Unified DATA MANAGEMENT, UDM), policy control function network elements (Policy Control Function, PCF), session management function network elements (Session Management Function, SMF), user plane function network elements (User Plane Function, UPF).
Taking the use of the dual-domain private network technology in the application environment as an example, a User Equipment (UE) can access through 4G or 5G, sign up for two data network identifiers (Data Network Name, DNN) at a Unified data management function network element (Unified DATA MANAGEMENT, UDM) of a home location, and respectively establish a public network session and a private network session by using the two data network identifiers. After the public network session and the private network session are established, the message data of the public network session and the private network session of the user equipment can be sent to the public network user plane function network element (User Plane Function, UPF) of the visiting place through the base station, and the message data can be distributed according to the distribution rule. The message data of the public network session is sent to the public network from an N6 interface of a public network user plane functional network element of a visiting place, the message data of the private network session is shunted to a private network user plane functional network element of a home place, the private network user plane functional network element carries out one-to-one replacement of a public network user equipment address and a private network user equipment address on the message data of the private network session, and the message data of the private network session is sent to a private network server from the N6 interface of the private network user plane functional network element. Based on the dual-domain private network technology, users such as teachers, students, enterprise staff, government staff and the like needing to access the private network can access the private network and the public network without changing cards or numbers and perception in the network coverage of operators such as a campus, an outside of the campus, a roaming place and the like.
In the above process, the two session establishment processes generally establish a public network session and then automatically trigger to establish a private network session, and the session management function network element (Session Management Function, SMF) of the visited place issues the service quality policy of the session to the base station to notify the base station to execute the service quality policy through the access and mobility management function network element (ACCESS AND Mobility Management Function, AMF) of the visited place. However, because the base station can only identify one session identifier of the same user, and the public network session and the private network session correspond to different session identifiers, after the base station completes the establishment of the public network session and executes the corresponding service quality policy, the service quality policy of the private network session cannot be issued to the base station to be executed, so that the service quality requirement of the private network session cannot be ensured.
Based on this, in an exemplary embodiment, as shown in fig. 2, a quality of service policy processing method is provided, which is illustrated by taking a session management function network element (Session Management Function, SMF) of the visited place in fig. 1 as an example, and includes the following steps:
Step S201, a first quality of service policy of a first session is obtained, and a second quality of service policy of a second session is obtained.
In particular, the first session and the second session may be protocol data unit (Protocol Data Unit, PDU) sessions between the user equipment and the data network established using different data network identities (Data Network Name, DNN) subscribed to by the user equipment. The visited session management function network element may use the data network identifier corresponding to the session to obtain, from the home network element, a quality of service (Quality of Service, qoS) policy subscribed by the data network identifier during the session establishment process.
For example, in case the user equipment signs up for two different data network identities, the first session in this step may be a session created using one of the data network identities and the second session may be a session created using the other data network identity. The visited session management function network element may obtain the first quality of service policy and the second quality of service policy according to the data network identifiers corresponding to the first session and the second session respectively.
Step S202, the first QoS strategy and the second QoS strategy are fused to obtain a third QoS strategy.
In this step, according to the obtained first quality of service policy and second quality of service policy, fusion processing may be performed on the first quality of service policy and the second quality of service policy, so as to obtain a third quality of service policy that can be compatible with the two quality of service policies. In this step, the quality of service requirements of the first session and the second session, for example, the requirement of access priority, the requirement of transmission rate, etc., may be determined according to the policy parameters of the first quality of service policy and the second quality of service policy, and then a third quality of service policy capable of guaranteeing the quality of service requirements of the first session and the second session when data of the two sessions are transmitted simultaneously may be determined according to the quality of service requirements of the two sessions.
Step S203, a session identifier of the first session is obtained.
Step S204, a third QoS policy and session identifier are sent to the base station.
Based on the third quality of service policy obtained in step S202, the session management function network element of the visited place may further obtain a session identifier of the first session in step S203, bind the third quality of service policy with the session identifier in step S204, and send the third quality of service policy to the base station via the mobility management function network element (ACCESS AND Mobility management Function, AMF), so that the base station can process data of the target session of the user equipment using the third quality of service policy. Wherein the target session may comprise the first session and/or the second session.
When the first session and the second session are established in sequence, for example, in a dual-domain private network scene, the first session is a public network session, the second session is a private network session, and the public network session is established before the private network session, the base station receives a service quality requirement policy corresponding to the first session when the first session is established. In this case, in this embodiment, the session that is established first may be used as the first session, the session that is established later may be used as the second session, and the third qos policy obtained by fusing the first qos policy and the second qos policy may be bound to the session identifier of the first session, so that after receiving the third qos policy and the session identifier, the base station may update its original qos policy corresponding to the session identifier to the third qos policy, and then use the third qos policy to process the target session of the user equipment.
When the first session and the second session are not established, the base station does not receive the service quality policy corresponding to any session, so that one of the two sessions can be selected as the first session, and the third service quality policy is bound with the session identifier of the session.
It will be appreciated that the user equipment may also sign up for a plurality of different data network identifications and establish different sessions successively. In this case, when a new session is established, one or more established sessions may be used as a first session, a session identifier of the first session is used as a session identifier of the first session, a qos policy obtained by fusing qos policies corresponding to all established sessions is used as a first qos policy, and then the newly established session is used as a second session, so that the qos policy of the new session and the qos policy of the established session may be fused according to the above steps, and the new qos policies compatible with all sessions may be bound to the same session identifier, so that the base station may update and execute the qos policies to ensure qos requirements of all sessions of the ue.
In the above-mentioned service quality policy processing method, by acquiring the first service quality policy of the first session and acquiring the second service quality policy of the second session, then fusing the first service quality policy and the second service quality policy to obtain a third service quality policy compatible with the first service quality policy and the second service quality policy, then acquiring the session identifier of the first session, and transmitting the third service quality policy and the session identifier to the base station for processing the target session. According to the scheme, the service quality strategies of the first session and the second session are fused to obtain the third service quality strategy which can be compatible with the first session and the second session, and then the third service quality strategy and the session identification of the first session are sent to the base station together, so that the base station can execute the third service quality strategy which is compatible with the service quality requirements of the first session and the second session based on the same session identification, and the service quality requirements of the two sessions are ensured while the base station is prevented from being abnormal.
Illustratively, in one embodiment, as shown in fig. 3, the merging the first quality of service policy and the second quality of service policy to obtain the third quality of service policy in this step may include:
Step S301, matching a first strategy parameter contained in a first quality of service strategy with a second strategy parameter contained in a second quality of service strategy according to a parameter type to obtain a plurality of strategy parameter pairs; different pairs of policy parameters correspond to different parameter types.
The quality of service policy may contain policy parameters of a number of different parameter types, wherein the parameter types may include an allocation and retention priority (Allocation and Retention Priority, ARP) parameter, a 5G quality of service identifier (5G QoS identifier,5QI) parameter, an aggregate maximum bit rate per Session (Session Aggregate Maximum Bit Rates, session AMBR) parameter, an upstream and downstream guaranteed stream bit rate (Guaranteed Flow Bit Rate, GFBR) parameter, an upstream and downstream maximum bit rate (Maximum Flow Bit Rate, MFBR) parameter, and so on. Based on this, in this step, the first policy parameter included in the first quality of service policy and the second policy parameter included in the second quality of service policy may be matched according to the parameter types, so as to obtain a plurality of policy parameter pairs corresponding to different parameter types respectively.
Step S302, fusing the plurality of strategy parameter pairs to obtain a plurality of third strategy parameters.
In this step, for each policy parameter pair, the policy parameter pairs may be fused to obtain a corresponding third policy parameter, so that after the fusion of all policy parameter pairs is completed, a plurality of third policy parameters corresponding to different parameter types may be obtained.
In an exemplary embodiment, each policy parameter pair may include a fourth policy parameter and a fifth policy parameter, and in this step, fusing the plurality of policy parameter pairs to obtain a plurality of third policy parameters may include: if the parameter type corresponding to the strategy parameter belongs to the level type, determining the fourth strategy parameter as a third strategy parameter; the first level of the fourth policy parameter is not lower than the second level of the fifth policy parameter; if the corresponding parameter type of the strategy parameter pair belongs to the value type, superposing a first parameter value of the fourth strategy parameter and a second parameter value of the fifth strategy parameter to obtain a third strategy parameter; the third parameter value of the third policy parameter is derived from a superposition of the first parameter value and the second parameter value.
Specifically, according to the usage of policy parameters of various parameter types, the parameter types corresponding to the policy parameters of the quality of service policy may include a parameter type belonging to a class type and a parameter type belonging to a numerical value type. Illustratively, the allocate and reserve priority (Allocation and Retention Priority, ARP) parameter may be used to identify the reserved and allocated priority, while the 5G quality of service identifier (5G QoS identifier,5QI) parameter may be used to identify the priority of different traffic, so these parameter types may be considered to be of a class type. And the aggregate maximum bit rate per Session (Session Aggregate Maximum Bit Rates, session AMBR) parameter, the upstream and downstream guaranteed stream bit rate (Guaranteed Flow Bit Rate, GFBR) parameter, the upstream and downstream maximum bit rate (Maximum Flow Bit Rate, MFBR) parameter, etc. in the quality of service policy are indicated by the size of the parameter values, so these parameter types can be considered as being of a numeric type.
The two strategy parameters contained in the strategy parameter pairs can be compared aiming at the strategy parameter pairs with the parameter types belonging to the level types, when the levels between the two strategy parameters are different, the strategy parameter with the higher level is used as a fourth strategy parameter, the strategy parameter with the lower level is used as a fifth strategy parameter, and then the fourth strategy parameter is determined as a third strategy parameter. When the levels of the two policy parameters are the same, any one of the two policy parameters can be used as a fourth policy parameter, the other one can be used as a fifth policy parameter, and then the fourth policy parameter can be determined as a third policy parameter. Based on the above, the level corresponding to the third policy parameter obtained by fusing the policy parameter pair is consistent with the higher level parameter in the policy parameter pair, so that compatibility of two policy parameters in the policy parameter pair can be realized.
And for the strategy parameter pair with the parameter type belonging to the value type, any one of the strategy parameter pairs can be used as a fourth strategy parameter, the other strategy parameter pair can be used as a fifth strategy parameter, then the first parameter value corresponding to the fourth strategy parameter and the second parameter value corresponding to the fifth strategy parameter are overlapped, and the overlapped value is used as a third parameter value corresponding to the third strategy parameter. Based on this, the third policy parameter can be compatible with the fourth policy parameter and the fifth policy parameter at the same time, so that the service quality requirements of the two sessions can be satisfied even if the first session and the second session need to be processed at the same time.
In the above process, aiming at the parameter types belonging to the class type or the numerical value type, the strategy parameter pairs are fused according to different modes, different strategy parameters can be subjected to differential fusion processing, and the third strategy parameters which can meet the requirements of the first session and the second session can be better obtained under the condition of not additionally increasing network load.
Step S303, according to the plurality of third policy parameters, a third QoS policy is obtained.
In this step, the multiple third policy parameters obtained in step S302 may be summarized and combined to obtain a complete third quality of service policy.
In this embodiment, policy parameters in the first quality of service policy and the second quality of service policy are matched according to parameter types, and each policy parameter pair is fused respectively, so that finer fusion processing can be performed on the two quality of service policies in the dimension of the parameters, a third quality of service policy with higher accuracy is obtained, and further the quality of service requirements of the first session and the second session are better satisfied.
In an exemplary embodiment, the method may further include the steps of: if the first quality of service policy includes a first target policy parameter, adding the first target policy parameter to a third quality of service policy; the first target policy parameter is not included in the second quality of service policy; if the second quality of service policy includes the second target policy parameter, adding the second target policy parameter to the third quality of service policy; the second target policy parameter is not included in the first quality of service policy.
Specifically, when the first session and the second session are different types of sessions, the quality of service policies corresponding to the two sessions may include parameters that cannot be matched according to the parameter types. Based on this, a parameter in which the mutual compatibility of the two quality of service policies can be achieved can be taken as a target policy parameter and added to the third quality of service policy. The target policy parameter may be a first target policy parameter included in the first quality of service policy but not in the second quality of service policy, or may be a second target policy parameter included in the second quality of service policy but not in the first quality of service policy.
Illustratively, in one embodiment, the first target policy parameter or the second target policy parameter comprises a parameter that guarantees a bit rate.
When one session is a Non-guaranteed bit rate (Non-Guaranteed Bit Rate, non-GBR) session and the other session is a guaranteed bit rate (Guaranteed Bit Rate, GBR) session, the qos policy corresponding to the guaranteed bit rate session includes parameters of guaranteed bit rates such as uplink and downlink guaranteed bit rate (Guaranteed Flow Bit Rate, GFBR) parameters, uplink and downlink maximum bit rate (Maximum Flow Bit Rate, MFBR) parameters, and the Non-guaranteed bit rate does not include these parameters. Based on this, the parameter of the guaranteed bit rate may be taken as a target policy parameter, and when the first quality of service policy contains the parameter of the guaranteed bit rate and the second quality of service policy does not contain the parameter, or the second quality of service policy contains the parameter of the guaranteed bit rate and the first quality of service policy does not contain the parameter, the parameter of the guaranteed bit rate contained in the first quality of service policy or the second quality of service policy may be added to the third quality of service policy. Based on this, when one of the first session and the second session is a guaranteed bit rate session and the other is a non-guaranteed bit rate session, the third quality of service policy may provide parameters of the guaranteed bit rate for both sessions, so as to be able to meet the requirements of the guaranteed bit rate session and to be compatible with the non-guaranteed bit rate session.
In this embodiment, the case that one of the two sessions may include a policy parameter of a certain type and the other one of the two sessions may not include a policy parameter, so that the policy parameter cannot be matched according to the parameter type is taken as a target policy parameter, and the target policy parameter is added to a third quality of service policy, so that the compatibility of the third quality of service policy to the first quality of service policy and the second quality of service policy is further ensured, and the quality of service requirements of the two sessions are ensured to be satisfied.
In an exemplary embodiment, as shown in fig. 4, a method for processing a qos policy is provided, which is described by taking a base station of the visited place in fig. 1 as an example, and includes the following steps:
step S401, receiving a third quality of service policy and a session identification of the first session.
Specifically, after the session management function network element of the visited place fuses the first quality of service policy of the first session and the second quality of service policy of the second session to obtain a third quality of service policy, the session management function network element of the visited place may bind the third quality of service policy with the session identifier of the first session, and send the third quality of service policy and the session identifier of the first session to the base station via the mobility management function network element (ACCESS AND Mobility management Function, AMF) of the visited place. Based thereon, the base station may receive a third quality of service policy and a session identification of the first session.
Step S402, processing the target session based on the third quality of service policy. The target session includes a first session and/or a second session.
Based on the third quality of service policy received in step S401 and the session identifier of the first session, the base station may process the data of the target session of the user terminal corresponding to the session identifier by using the third quality of service policy in this step. Wherein the target session may comprise the first session and/or the second session.
If the base station has a service quality policy corresponding to the session identifier, the base station may update the original service quality policy to a third service quality policy according to the received third service quality policy and the session identifier in this step, and process the first session and/or the second session of the corresponding user terminal by using the updated service quality policy.
In this embodiment, by receiving the session identifier of the first session and the third quality of service policy obtained by fusing the first quality of service policy of the first session and the second quality of service policy of the second session, the base station can obtain a policy capable of meeting the quality of service requirements of the first session and the second session at the same time under the condition that only one session identifier needs to be identified, so that the base station can apply the policy to the processing of the two sessions and meet the quality of service requirements of the two sessions at the same time.
To further illustrate the quality of service policy handling method of the present application, the following description will refer to detailed embodiments in connection with a session establishment procedure for a dual-domain private network.
As shown in fig. 5, a User Equipment (UE) may sign up a general data network identifier and a private data network identifier for a public network and a private network, respectively, and then establish a public network session and a private network session between the UE and the data network sequentially using the general data network identifier and the private data network identifier. Based on this, in this embodiment, the public network session may be used as the first session, and the private network session may be used as the second session.
The public network session can be established by the user equipment by using the universal data network identifier, and then the session management function network element (Session Management Function, SMF) of the visiting place carries the universal data network identifier to request the policy control function network element (Policy Control Function, PCF) of the home place to issue the corresponding subscription policy. Then, the visited session management function network element may receive a first quality of service policy and a dynamic offloading rule applicable to the public network session, which are issued by the home policy control function network element. Wherein the dynamic separation rule comprises a private data network identifier subscribed by the user equipment. Further, the visited session management function network element may inform the base station to execute the first quality of service policy and complete the establishment of the public network session (i.e. the first session).
After the public network session is established, the session management function network element of the visiting place can use the special data network identifier contained in the dynamic distribution rule to trigger the establishment of the private network session (namely the second session). The visited session management function network element may initiate a private network session establishment request to the home session management function network element using the private data network identifier, and receive a private network session establishment response sent by the home session management function network element. The private network session establishment response includes a second quality of service policy applicable to the private network session issued by the home policy control function network element (Policy Control Function, PCF) to the home session management function network element.
The visiting place session management function network element completes the establishment of the second session and the acquisition of the first service quality strategy of the public network session and the second service quality strategy of the private network session. Based on the above, the visited session management function network element may fuse the first quality of service policy and the second quality of service policy to obtain a third quality of service policy that can be compatible with the two quality of service policies. And then binding the third quality of service policy to the session identifier of the public network session, and transmitting the third quality of service policy and the session identifier to the base station.
The base station can update the first service quality strategy received in the public network session establishment process according to the received third service quality strategy and the session identification, and the private network session and the public network session of the user terminal are processed by using the third service quality strategy.
According to the scheme, in the session establishment process of the dual-domain private network, the policy decision capability of the session management function network element of the visiting place is enhanced, so that the policy decision capability of the session management function network element of the visiting place is used for carrying out fusion processing on the service quality policies of the public network session and the private network session, and then the service quality policies are uniformly sent to the base station side, so that the base station can obtain a new policy compatible with the service quality requirements of the two sessions, and the requirements of the two sessions can be simultaneously ensured. In addition, after the new strategy is obtained, the new strategy is bound to the session identifier of the public network session, the situation that the base station can only identify one session identifier can be fully considered, so that the base station can update the strategy without abnormality caused by different session identifiers, and the new strategy can be ensured to be smoothly executed by the base station.
