Description

Method and device for sending information

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for transmitting information.

Background

In order to guarantee quality of service (QoS) of traffic transmission in a communication system, a control mechanism of QoS flow granularity based on end-to-end quality of service flow is proposed in 5G. The control mechanism of QoS flow granularity refers to that the same QoS parameter is adopted to process the data packet controlled by the same QoS flow in the transmission process. For the transmission of downlink data packets, a User Plane Function (UPF) performs matching of uplink and downlink data packets based on a Service Data Flow (SDF) level filter, and classifies the downlink data packets into corresponding QoS flows. The UPF marks each downlink packet with a QoS Flow Identifier (QFI) in a downlink packet tunneling header, and then transmits the QoS Flow Identifier (QFI) to AN Access Network (AN). The AN performs QoS flow and Data Radio Bearers (DRBs) binding of one or more QoS flows to the same DRB. And after receiving the downlink data packet sent by the UPF, the AN sends the downlink data packet to the UE through processing. For the transmission of the uplink data packet, the UE needs to match the uplink data packet to the corresponding QoS flow based on the QoS rule configured on the network side, and then map the uplink data packet to the DRB for transmission.

In order to save the signaling overhead caused by the network side issuing the QoS rules to the UE, a Reflection QoS (RQ) mechanism is introduced in the 5G network. In a Reflective QoS scene, the UE does not need to acquire a QoS rule from a signaling surface of a network, and the QoS of an uplink data packet sent by the UE is transmitted by adopting a QoS flow consistent with downlink data.

However, currently, no specifications for interaction flow between the control plane and the user plane under the RQ mechanism exist in the industry.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

First, the network elements and their functions related to the embodiments of the present application will be briefly described.

Access and mobility management function (AMF), the main functions of the AMF include but are not limited to: access and mobility related functions such as connection management, mobility management, access authentication and authorization, reachability management, security context management, etc.

Session Management Function (SMF), the functions of SMF include but are not limited to: session management (e.g., establishment, modification, and release of sessions, maintenance of tunnels between UPFs and ANs), selection and control of UPFs, roaming, etc. session-related functions. Wherein, the session management function includes: session establishment, modification and release, and tunnel maintenance between the UPF and the AN.

Policy Control Function (PCF), the functions of a PCF include, but are not limited to: the method comprises the steps of making a unified strategy, providing strategy control, acquiring contract data related to strategy decision from a Unified Data Repository (UDR) and the like.

A Data Network (DN) for providing a network of services or contents. A DN may be identified using a DNN.

A User Plane Function (UPF), which is mainly responsible for routing and forwarding user plane data.

A Radio Access Network (RAN) is an access device through which a UE accesses a mobile communication system in a wireless manner, and may be a base station NodeB, an evolved node b, a 5G mobile communication system, or a base station in a New Radio (NR) communication system, a base station in a future mobile communication system, an access node in a WiFi system, and the like. The radio access network equipment may also be jointly formed by a radio access network controller and a base station. The embodiments of the present application do not limit the specific technologies and the specific device forms adopted by the radio access network device.

Fig. 1 is a system architecture suitable for use with embodiments of the present application. Fig. 1 includes AMF, SMF, PCF, (R) AN, UPF and UE. Further, AUSF, UDM and the like are included. The signalling interface between these network elements is shown in figure 1. For example, the UE and the AMF communicate via an N1 interface. Communication between the AMF and the SMF is performed via an N11 interface, and the like. In the following embodiments, the information and/or data transmission between the network elements involves corresponding interfaces, which are described in conjunction with specific embodiments.

In the architecture shown in fig. 1, in order to guarantee quality of service (QoS) in a 5G communication system, a control mechanism of QoS flow granularity on an end-to-end basis (between UE and UPF) is proposed. The control mechanism of the QoS flow granularity refers to that the same QoS parameter is adopted by the data packet controlled by the same QoS flow for transmission processing. Here, QoS parameters include, but are not limited to: processing priority, packet delay, packet loss rate, bit rate, etc.

Structure of QoS referring to fig. 2, fig. 2 is a schematic diagram of the structure of QoS.

As shown in fig. 2, for a UE, one or more Packet Data Unit (PDU) sessions can be established with the core network, and each access network AN can establish one or more Data Radio Bearers (DRBs) for each session. The non-access stratum (NAS) and the UPF of the UE map the uplink and downlink packets onto one QoS flow based on a packet filter. The Access Stratum (AS) and RAN of the UE associate the QoS flow of uplink and downlink to a radio data bearer (DRB) for transmission.

The method for sending information provided by the present application is described below, and the method can be applied to a scenario in which interaction is performed between a control plane and a user plane under an RQ mechanism.

It should be noted that the names of the network elements AMF, SMF, and PCF described herein should not be used to limit the technical solutions of the embodiments of the present application. For example, in some communication systems, the names of some network elements may be different from those of the network elements AMF, SMF, and PCF described herein, but if these network elements have the same functions as those of the AMF, SMF, and PCF in the embodiment of the present application, these network elements should also fall within the scope of the embodiment of the present application.

The following describes in detail a method of transmitting information according to an embodiment of the present application.

First, from the perspective of the UE, the UE may send information whether to support RQ to the network side through a registration procedure or a session procedure.

Mode 1

The UE sends first indication information to the AMF through a registration process, wherein the first indication information is used for indicating the reflection quality of service (RQ) capability of the UE. Wherein, the RQ capability may characterize whether the UE supports RQ.

Referring to fig. 3, fig. 3 is an example of a UE transmitting information whether the UE supports RQ through a registration procedure.

301. And the user equipment UE sends the first indication information through a registration process. The AMF receives the first indication information through a registration process. For example, the UE may transmit the first indication information to the AMF through a registration request message.

Wherein the first indication information is used for indicating whether the UE supports RQ. Specifically, the first indication information may be UE RQCapability. One possible implementation manner is that the first indication information has two values, one value corresponds to the support of the RQ, and the other value corresponds to the non-support of the RQ. For example, when the value of the first indication information is 1, the RQ is supported, and when the value of the first indication information is 0, the RQ is not supported.

The first indication information may also be used to indicate that the UE supports RQ, that is, the first indication information only has one value and is used to indicate that RQ is supported.

In the embodiment of the present application, the RQ mechanism refers to that the uplink data packet is transmitted by using QoS flow consistent with that of the downlink data packet. Whether the UE supports the RQ or not can be expressed herein, and whether the UE supports the RQ mechanism or not can also be expressed. Whether the network adopts the RQ or not can also be expressed as whether the network adopts the RQ mechanism or not.

The AMF may know that the UE supports RQ according to the first indication information. The AMF performs step 302.

302. The AMF sends the first indication information to the SMF through the session flow. For example, the AMF may send the first indication information to the SMF through an interaction message Nsmf _ pdusesion _ CreateSMContext Request of the AMF and the SMF.

303. The SMF first indication information is sent to the PCF. For example, the SMF may send the PCF via an Npcf _ SMPolicyControl _ Get servitization message.

In this embodiment, the AMF sends the first indication information to the SMF through the session flow, and the SMF or the PCF determines the control policy for the SDF according to the first indication information.

It is understood that the AMF may save the first indication information after acquiring the first indication information from the registration request message. And then the AMF encapsulates the first indication information in the session management context message and sends the first indication information to the SMF. After receiving the first indication information, the SMF encapsulates the first indication information in an event open notification message and sends the event open notification message to the PCF.

304. And the PCF determines the control strategy of the SDF according to the first indication information.

Specifically, the PCF may obtain subscription data of the UE and/or subscription data and/or service information of DNN granularity, and determine a control policy (which may also be referred to as a control policy for short) for a Service Data Flow (SDF) according to at least one of the subscription data of the UE, the subscription data of the DNN granularity, the service information, and the first indication information.

It should be noted that the subscription data of the UE in the UDR includes subscription data of the UE and subscription data of DNN granularity. The subscription data referred to in step 304 is subscription data of DNN granularity.

In fig. 3 of the method 1, in one possible case, the PCF determines the control policy for the SDF according to the subscription data of DNN granularity acquired from the UDR in combination with the received first indication information.

In another possible scenario (not shown in fig. 3), the PCF may also determine the control policy for the SDF based on the DNN-sized subscription data obtained from the UDR.

305. The PCF sends the SMF the control policy for the SDF.

Wherein the control policy of the SDF is included in the PCC rules.

And the UE determines whether to detect the RQ field of the downlink data packet or not according to the control strategy.

For example, if the control policy is that the network applies RQ to a certain SDF (hereinafter referred to as a first SDF), the UE detects the RQ field of the downlink packet of the first SDF. And if the control strategy is that the network does not adopt the RQ for the first SDF, the UE does not detect the RQ field of the downlink data packet of the first SDF.

Specifically, in the embodiment shown in fig. 3, after determining the control policy, the PCF sends a fourth indication to the SMF, where the fourth indication indicates whether the network employs RQ. And the SMF reprocesses the fourth indication information to generate second indication information. The SMF sends the second indication information to the UE. And the UE can know whether the network adopts the RQ or not according to the second indication information.

Or, after determining the control policy, the PCF may send the fifth indication information to a Radio Access Network (RAN) through the SMF, and the RAN generates the sixth indication information according to the fifth indication information and sends the sixth indication information to the UE. The UE may know whether the network supports RQ according to the sixth indication information.

Therefore, in the embodiment of the present application, when one network element (e.g., network element a) sends information to another network element (e.g., network element B), network element a may send information to network element B directly without going through other network elements, and without performing any processing (i.e., transparent transmission) on the information sent by network element a. Or, after the network element a sends out the information, the information is forwarded by other network elements or networks, or the information is re-encapsulated, and the network element B finally receives the re-encapsulated information. In other words, the information sent by the network element a and the information received by the network element B are considered to express the same meaning regardless of whether the encapsulation forms of the information sent by the network element a and the information received by the network element B are completely the same. The embodiment of the application does not limit the process of repackaging the information and does not limit the network element for repackaging the information. Other variants or possibilities will occur to those skilled in the art on the basis of the technical solutions presented in the present application.

In the embodiment of the present application, the RQ field may also be referred to as an RQ identification bit (RQ identifier bit).

In addition, the SMF instructs the UPF to tag the RQ field of the packet of the first SDF.

And if the second indication information indicates that the network adopts RQ for the first SDF, the SMF indicates the UPF to mark the downlink data packet of the first SDF with the first mark. And if the second indication information indicates that the network does not adopt the RQ for the first SDF, the SMF indicates the UPF to mark the downlink data packet of the first SDF by the second mark. For example, the first flag may be "1" and the second flag may be "0".

Further optionally, the second indication information indicates that the network employs RQ, and the second indication information also indicates the granularity of RQ supported by the network. Wherein, the RQ granularity includes a service data flow SDF granularity, a packet data unit PDU session granularity, a data network DN granularity, or a UE granularity.

In the method flow shown in fig. 3, the PCF determines whether to apply RQ for a certain SDF according to the received first indication information. Another example is given below in connection with fig. 4, in which fig. 4, whether to employ RQ for a certain SDF is determined by the SMF.

Referring to fig. 4, fig. 4 is another example of whether the UE supports RQ through a registration procedure.

401. The UE sends the first indication information through a registration process, and the AMF receives the first indication information through the registration process.

402. The AMF sends the first indication information to the SMF.

403. And the SMF determines a control strategy for the SDF according to the first indication information and the local strategy.

In addition, the SMF instructs the UPF to label the data packet of a certain SDF according to the determined control strategy of the SDF. For example, if the network employs RQ for the first SDF, the SMF instructs the UPF to make a first flag, e.g., 1, in the RQ bit of the encapsulation header of the downstream packet of the first SDF. If the network does not use the RQ for the first SDF, the SMF instructs the UPF to make a second flag, e.g., 0, in the RQ bit of the encapsulation header of the downstream packet of the first SDF. Compared with the method for sending the first indication information through the session process, the method for sending the first indication information through the registration process can effectively save signaling overhead for reporting the first indication information.

In the embodiment shown in fig. 4, the SMF receives a Policy and Charging Control (PCC) rule from the PCF and determines a control policy for the SDF in conjunction with the PCC rule and the first indication information.

In another possible implementation, for example, if the PCF is not deployed in the network, the SMF may also determine the control policy for the SDF according to the local policy and the first indication information.

The local policy may be generated by the DNN RQ subscription data, the service information of the UE, and the like. In other words, in the case where the PCF is not deployed in the network, subscription data, service information, etc. of the UE should be configured on the SMF, so that the SMF generates a local policy according to these information and/or data. Further, in the case that the SMF receives the first indication information or the third indication information, the control policy for the SDF is determined by combining the first indication information and the local policy, or combining the third indication information and the local policy, or combining the first indication information, the third indication information and the local policy. (the third indicating information will be described in detail below)

In the embodiment shown in fig. 3 and 4 of the mode 1, the UE sends first indication information whether the UE supports RQ to the network side through a registration procedure. Compared with the method for sending the first indication information through the session process, the method for sending the first indication information through the registration process can effectively save signaling overhead for reporting the first indication information.

Mode 2

And the UE sends third indication information to the SMF through the session flow, wherein the third indication information is used for indicating the willingness of the UE to adopt RQ.

Referring to fig. 5, fig. 5 is an example of the UE's willingness to send RQ or not by the UE through a session flow.

501. And the UE sends third indication information to the SMF, and the SMF receives the third indication information.

In the foregoing fig. 3 and fig. 4, the first indication information sent by the UE through the registration procedure is used to indicate the RQ capability of the UE, where the RQ capability is used to characterize that the UE supports RQ or does not support RQ. In fig. 5, the third indication information sent by the UE to the SMF through the session flow is used to indicate whether the UE intends to adopt RQ.

The willingness of RQ granularity may be SDF granularity, PDU session granularity, DN granularity, or UE granularity. The present application is not limited.

Therefore, in the foregoing embodiment, the first indication information may specifically be UE RQ Capability. The third indication information here may be specifically RQ reference.

In step 501, the UE sends the third indication information to the AMF through the session flow, and the AMF forwards the third indication information to the SMF. That is, in the session flow, the AMF does not interpret the content of the third indication information, and simply forwards the third indication information from the UE to the SMF.

502. The SMF forwards the third indication information to the PCF, and correspondingly, the PCF receives the third indication information.

For example, the SMF may send the third indication information to the PCF via an Npcf _ SMPolicyControl _ Get service message of the session flow.

Likewise, the SMF forwards the third indication to the PCF for the PCF to determine a control policy for the SDF based on the third indication.

503. And the PCF determines a control strategy for the SDF according to the third indication information.

In step 503, specifically, the PCF may obtain subscription data and/or subscription data with DNN granularity and/or service information of the UE, and determine the control policy for the SDF according to at least one of the subscription data of the UE, the subscription data with DNN granularity, the service information, and the third indication information.

In the embodiment of the present application, the service information includes, but is not limited to, QoS requirement information of the service. Here, the subscription data is subscription data of DNN granularity.

504. The PCF sends the SMF the control policy for the SDF.

Subsequently, the SMF indicates to the UE through the AMF whether the network employs RQ according to the control policy.

Specifically, if the network employs RQ, the SMF may send RQ allowed to the UE through the AMF. If the network does not adopt the RQ, the SMF may send the RQ not allowed to the UE through the AMF.

Further, the UE determines whether to detect the RQ field of the downlink packet according to the received indication information of whether the network employs the RQ. And if the UE receives the RQ allowed, the UE detects the RQ field of the downlink data packet. If the UE receives the RQ not allowed, the UE does not detect the RQ field of the downlink packet.

In addition, the SMF needs to instruct the UPF to mark the RQ field of the downlink packet according to the second indication information. The UPF marks the RQ field of the downstream packet differently according to the different meaning indicated by the second indication information. For example, if the second indication indicates that the network uses RQ, the SMF indicates the UPF to mark the downstream packet as the first mark. And if the second indication information indicates that the network does not adopt the RQ, the SMF indicates the UPF to mark the downlink data packet as a second mark. For example, the first flag may be "1" and the second flag may be "0".

Optionally, in a case that the second indication information indicates that the network employs RQ, the second indication information further indicates that the network supports RQ granularity, wherein the RQ granularity includes SDF granularity, PDU session granularity, DN granularity, or UE granularity.

It can be seen that the embodiment shown in fig. 5 is different from the embodiment shown in fig. 3 above in the indication information sent by the UE to the network side. The first indication information sent by the UE in fig. 3 is used to indicate RQ capability of the UE, where the RQ capability is used to characterize that the UE supports RQ or does not support RQ. And the third indication information sent by the UE in fig. 5 is used to indicate whether the UE intends to adopt RQ, which indicates an intention of the UE to adopt RQ.

Referring to fig. 6, fig. 6 is another example of the UE's willingness to send, through a session flow, whether the UE employs RQ.

601. And the UE sends third indication information to the SMF through the session flow, and the SMF receives the first indication information through the session flow.

Wherein the third indication information is used for indicating whether the UE intends to adopt RQ. Specifically, the third indication information may be RQ reference.

In this application, the RQ reference may be generated according to a UE path selection policy (URSP) received by the UE and sent by the network, or may be generated in other manners, which is not limited in this embodiment.

Specifically, the UE forwards the third indication information to the SMF through the AMF, which does not interpret the content of the third indication information.

602. And the SMF determines a control strategy for the SDF according to the third indication information and the local strategy.

Here, the PCC rule generated by the PCF is a control policy for the SDF in the embodiment of the present application. That is, in this scheme, the control strategy for the SDF is generated by the PCF.

Specifically, the PCC rule sent by the PCF to the SMF may include RQ control information. Wherein the RQ control information is used to indicate a control strategy for the SDF.

Similar to the embodiment in which the UE sends the first indication information through the registration procedure, in the embodiment shown in fig. 6, the control management of the SDF by the SMF also includes the following two aspects.

(1) The SMF indicates to the UE whether the network employs RQ in order for the UE to determine whether to detect the RQ field of the downlink packet.

And if the SMF indicates that the network adopts the RQ, the UE detects the RQ field of the downlink data packet. If the SMF indicates that the network does not adopt the RQ, the UE does not detect the RQ field of the downlink data packet.

(2) The SMF instructs the UPF to mark the RQ field of the downstream packet.

If the SMF determines to adopt the RQ for the first SDF, the SMF indicates the UPF to make a first mark in the RQ bit of the encapsulating packet header of the downlink data packet of the first SDF. If the SMF determines that the first SDF does not adopt the RQ, the SMF indicates the UPF to make a second mark in the RQ bit of the encapsulating packet header of the downlink data packet of the first SDF. For example, the first flag may be "1" and the second flag may be "0". Or not marked.

In summary, in the method 1, the UE reports the first indication information of whether the UE supports RQ to the network side (specifically, to the AMF) through the registration procedure. In the embodiment shown in fig. 3 in the mode 1, the network element PCF determines, according to the first indication information reported by the UE, whether the network employs RQ in combination with the subscription data and/or the service information of the UE. In the embodiment shown in fig. 4 of the mode 1, the network element SMF determines, according to the first indication information reported by the UE, whether the network employs the RQ in combination with the local policy on the SMF.

In the method 2, the UE reports the third indication information of the will of whether the UE adopts RQ to the network side (specifically, to the SMF) through the session flow. In the embodiment shown in fig. 5 in the mode 2, the network element PCF determines, according to the third indication information reported by the UE, whether the network employs RQ in combination with the subscription data of the UE and/or the subscription data of DNN granularity and/or the service information. In the embodiment shown in fig. 6 of the mode 2, the network element SMF determines, according to the third indication information reported by the UE, whether the network employs the RQ in combination with the local policy on the SMF.

In combination with the mode 1 and the mode 2, in the mode 1, compared with the mode 2 in which the UE reports the RQ capability through the registration procedure, the transmission resource from the UE to the AMF can be saved.

And by adopting the mode 2, the UE can report the desire of supporting the RQ, so that the UE can send the desire of whether to support the RQ to the network according to the actual requirement of the UE.

Mode 3

And the UE sends the first indication information through the registration process and sends the third indication information through the session process.

In the method 3, reference may be made to the method 1 for implementing a process in which the UE sends the first indication information through the registration procedure. The process of sending the third indication information by the UE through the session flow may be implemented as reference to mode 2. And will not be described in detail herein.

In the embodiment 3, unlike the foregoing embodiments 1 and 2, in the embodiment 3, the PCF or SMF on the network side determines whether the network uses the RQ by combining the first indication information and the third indication information.

Taking the PCF as an example, after receiving the first indication information and the third indication information, the PCF determines whether the network adopts RQ by combining the first indication information and the third indication information. Specifically, the PCF may determine whether the network employs the RQ according to the subscription data and/or the service information of the UE, in combination with the first indication information and the third indication information.

SMF is also similar and will not be described in detail.

In one possible case, the PCF may obtain subscription data of DNN granularity for the UE from the subscription database UDR and determine the control policy for the SDF in combination with the first indication and the third indication.

In one possible case, the SMF may determine the control policy for the SDF according to the PCC rule received from the PCF in combination with the first indication information and the third indication information.

In addition, in the mode 3, the SMF may further determine the control policy for the SDF according to the local policy, the first indication information, and the third indication information. For example, in the case where the PCF is not deployed in the network, subscription data and/or service information of the UE should be configured or pre-stored on the SMF. And the SMF generates a local strategy according to locally stored subscription data and/or service information of DNN granularity of the UE under the condition of receiving the first indication information and the third indication information, and determines a control strategy for the SDF by combining the local strategy, the first indication information and the third indication information.

The PCF determines the control policy for the SDF based on any one of the above modes 1, 2, and 3, so that the PCF determines the control policy to involve more information, and thus, the control policy is more accurate and reasonable than the PCF determines the control policy for the SDF only according to subscription data and/or service information of the UE, etc.

In addition, for the situation that the SMF determines the control policy for the SDF through the local policy in combination with the mode 1, the mode 2, or the mode 3, the method for the network to formulate the RQ-related policy can be perfected in the scenario where the PCF is not deployed in the network.

The above describes the interaction flow of the control plane and the user plane in the embodiment of the present application. The following describes in detail a registration procedure and a session procedure of the UE related in this embodiment to describe how the UE specifically reports the first indication information to the network side through the registration procedure, or how the UE reports the third indication information to the network side through the session procedure.

First, a registration procedure of the UE is described.

Referring to fig. 7, fig. 7 is a schematic diagram illustrating a UE sending first indication information through a registration procedure in an embodiment of the present application.

701. The UE sends a first registration request to AN access network AN, wherein the registration request carries the UE RQ Capability.

Wherein the UE RQ Capability indicates that the UE supports RQ. To avoid the encumbrance of the description, the UE RQCapability is hereinafter referred to as the first indication information.

In step 701, the access network AN may be a radio access network RAN. The following description will be given taking AN as AN example.

702. The AN performs AN AMF selection procedure.

In the embodiment of the present application, the AMF selected by AN is referred to as a first AMF.

703. And the AN sends a second registration request to the first AMF, wherein the second registration request carries the UE RQ Capability.

704. The first AMF determines a second AMF according to the second registration request, and sends a UE context transfer request to the second AMF.

The second AMF is AN AMF before the AN performs the AMF selection procedure. To distinguish from the first AMF, the AMF before the AN performs the AMF selection procedure is referred to herein as a second AMF.

705. The second AMF sends a response message of the UE context transfer request to the first AMF.

Wherein, the response message includes PCF information. The PCF information includes an IP address of the PCF used by the second AMF (e.g., a prefix of the IPv4 address or the IPv6 address) or a Fully Qualified Domain Name (FQDN) of the PCF.

Further, PCF instance information is also included in the response message. The PCF implementation information is obtained by the second AMF from the NRF.

706. The first AMF sends an identity request to the UE.

707. The UE sends a response message identifying the request to the first AMF.

Step 706-707 is an optional step and may not be performed.

708. The first AMF performs an authentication service function (AUSF) selection procedure.

The main function of the AUSF is to support security-related authentication and authentication functions of the UE and the network.

The AUSF shown in fig. 5 is the AUSF determined after the first AMF performs the AUSF selection procedure.

709. Authentication and security procedures are performed between the UE and the network side.

710. The first AMF sends a registration completion notification to the second AMF.

In step 710, if the first AMF determines to use the PCF used by the second AMF, the registration completion notification carries indication information 1, where the indication information 1 is used to indicate that the second AMF only deletes the UE context stored in the second AMF when receiving the UE context deletion notification sent by the UDM, and does not need to initiate a policy deletion service to the PCF.

711. The first AMF initiates an identification acquisition process to the UE.

Here, step 511 is an optional step.

712. The AMF and the EIR perform equipment identity EIR _ MEI check acquisition service.

Wherein, the EIR _ MEI is called an equation identity register _ mobile equation identity in all english. When the UE is a mobile phone, the device identifier EIR _ MEI may be an identifier of the mobile phone, and the identifier is independent of a (subscriber identification module, SIM) card. The detailed information can refer to the prior art and is not detailed here.

713. The first AMF performs a User Data Management (UDM) selection procedure.

The UDM shown in fig. 7 is the UDM determined after the first AMF performs the UDM selection procedure.

714. And the first AMF and the UDM execute registration and subscription acquisition processes.

In addition, after receiving the registration request or subscription request of the first AMF, the UDM sends a UE context deregistration notification to the second AMF.

715. If the first AMF determines that PCF information provided by the second AMF is unavailable, the first AMF performs a PCF selection procedure.

716. And if the first AMF determines that the PCF information provided by the second AMF is available and the PCF indicated by the PCF information is the PCF used by the second AMF, the first AMF sends a control strategy acquisition request to the PCF.

The control policy acquisition request carries information (denoted as indication information 2) indicating that the PCF updates the local UE context.

Further, if the mobility policy of the UE acquired by the first AMF from the second AMF is available, the control policy acquisition request carries information (denoted as indication information 3) indicating that the PCF does not need to send the mobility policy of the UE.

And the PCF updates the local UE context according to the indication information 2 in the control strategy acquisition request. The updated content mainly includes storing the identification information of the first AMF (denoted as ID of the first AMF) in the UE context and deleting the identification information of the second AMF (denoted as ID of the second AMF).

717. The first AMF transmits an event open notification message to the SMF.

Wherein the event openness notification message includes a PDU status.

718. The first AMF sends an N2 request to N3 WF.

719. N3WF returns the response message of the N2 request to the first AMF.

720. If the second AMF carries indication information 1 in the registration completion notification from the first AMF received in step 510, the second AMF only deletes the local UE context.

And if the registration completion notification does not carry the indication information 1, the second AMF initiates a control strategy deletion request to the PCF.

Two of the steps 720 in fig. 7 represent one of the steps performed as the case may be.

721. The first AMF transmits a registration receipt message to the UE.

722. The UE sends a registration complete message to the first AMF.

The above steps 701 and 722 are the registration procedure of the UE.

It can be seen that in step 701, the UE may carry UE RQCapability (i.e., first indication information) in the first registration request sent to the AN. Subsequently, in step 702, the AN carries the ue rq Capability when sending the second registration request to the AMF. Thus, the UE reports to the network side (specifically, to the AMF) whether it supports RQ in the registration procedure.

It can be appreciated that since the registration procedure of the UE is only performed when the UE accesses the network, it generally does not occur frequently. Therefore, the UE reports the first indication information to the network side through the registration process, and the signaling overhead can be saved.

The following describes a session procedure of the UE.

Referring to fig. 8, fig. 8 is a schematic diagram illustrating a UE sending first indication information through a session procedure according to an embodiment of the present application.

801. The UE sends a PDU session setup request to the AMF.

Wherein the PDU session setup request carries the RQ reference (i.e., the third indication information).

Optionally, the session management context message further includes UE RQ Capability (i.e., the first indication information).

It should be understood that the AMF illustrated in fig. 8 is the first AMF illustrated in fig. 7.

802. The AMF performs an SMF selection procedure.

The SMF shown in fig. 8 is the SMF determined after the AMF has performed the AMF selection procedure.

803. The AMF sends a session management context message to the SMF.

In particular to an Nsmf _ pdusesion _ CreateSMContext Request service message.

Wherein, the session management context message contains PCF information.

In addition, the session management context message also includes an RQ reference (i.e., third indication information).

In a non-roaming scenario, the AMF directly provides PCF (home PCF, H-PCF) information of a home domain selected by the AMF to the SMF.

In a Local Breakout (LBO) session in a roaming scenario, the AMF determines that an attribute of the session is LBO. The AMF provides PCF (visited PCF, V-PCF) information of the visited domain selected by itself. Optionally, the session management context message further includes V-PCF instance information. Further, the AMF provides PCF information to the SMF based on the PCF's service object (e.g., the PCF serves SMF in the PLMN, or the PCF serves SMF in the slice). That is, when the PCF serves a Public Land Mobile Network (PLMN) granularity, or the handoff of the PCF service includes a handoff where the SMF is located, the AMF provides PCF information to the SMF.

In addition, in a roaming scenario, if the SMF (V-SMF) of the visited domain receives the first indication information (UE RQCapability) and the third indication information (rqreference), the first indication information and the third indication information are sent to the SMF (home SMF, H-SMF) of the home domain.

804. The SMF and the UDM execute a registration process or a subscription acquisition process.

805. The SMF sends a session creation reply to the AMF.

806. The UE and the network perform a PDU session authentication and authorization procedure.

Step 806 is optional and may not be performed.

807. The SMF receives a session creation management context message that includes PCF information. And the SMF executes the PCF selection process according to the local strategy.

It should be appreciated that the session creation management context message received by the SMF in step 807 is sent by the AMF in step 603.

Specifically, if the AMF-provided V-PCF is available, the SMF uses the AMF-provided V-PCF. If the V-PCF provided by the AMF is not suitable, if a V-PCF instance (V-PCF instances) is available, the SMF selects the V-PCF according to the V-PCF instance.

Further, if there is no suitable V-PCF, the SMF selects the V-PCF by initiating a PCF discovery procedure to the NRF.

808. The SMF requests the PCF to acquire the PCC rule.

Specifically, the SMF requests the PCF to acquire a PCC rule (also referred to as a PCC policy) via an Npcf _ SMPolicyControl _ Get message.

Still further, the SMF initiates a service request to the V-PCF selected in the PCF discovery procedure to obtain a PCC Rules (i.e., a PCC rule) from the V-PCF.

Optionally, in step 808, the SMF may carry the UE RQCapability (i.e., the first indication information) in an Npcf _ SMPolicyControl _ Get message, for indicating to the PCF whether the UE supports RQ.

And the PCF acquires the subscription data and/or DNN RQ subscription data and/or service information of the UE, and determines whether to adopt RQ for a certain SDF or not according to at least one item of the subscription data, the service information, the first indication information and the third indication information.

As can be understood from the above description, in this embodiment, the PCF determines, according to the RQPreference reported by the UE, whether the network uses RQ in combination with the acquired subscription data and/or service information of the UE.

809. The SMF performs a UPF selection procedure.

810. The SMF sends an event open notification message to the PCF.

Optionally, in step 809, the SMF may carry an rqreference (i.e., the third indication information) in the subscription message of the PCC policy sent to the PCF. Specifically, the Nsmf _ EventExposure _ Notify service message.

Optionally, in step 809, the SMF may carry the UE RQ Capability (i.e., the first indication information) in the Nsmf _ EventExposure _ Notify service message, for indicating to the PCF whether the UE supports RQ.

According to the descriptions in step 808 and step 810, that is, in the session flow, the SMF may carry the RQ reference or the UE RQ Capability in the session creation management context message sent to the PCF in step 808. Alternatively, the RQPreference or the UE RQ Capability may be carried in the event opening in step 809 instead of being carried in the session creation management context message. Therefore, the RQ Preference or the RQCapability sent by the UE through the session procedure is forwarded to the PCF, so that the PCF determines whether the network adopts RQ according to the RQ Preference or the RQ Capability.

811. The PCF sends a session management policy update notification to the SMF.

The PCF acquires the subscription data and/or service information and/or DDN subscription data of the UE, and determines whether to adopt RQ for a certain SDF according to at least one of the subscription data and the service information, the RQ Capability of the UE and the RQ reference.

Similarly, if the PCF determines to use RQ for the first SDF, the PCF may carry RQ allowed in the session management update notification sent to the SMF, indicating that the network supports RQ. If the PCF determines not to use RQ for the first SDF, the PCF may carry RQ not allowed in the session management notification, indicating that the network does not support RQ. Subsequently, the SMF indicates to the UE whether the network supports RQ.

812-.

In the embodiment shown in fig. 8, the UE reports the willingness of the UE to adopt RQ to the PCF on the network side by carrying the RQ reference in the session establishment request. In a possible case, the UE reports whether the UE supports RQ to the PCF on the network side by carrying the UE RQCapability in the session establishment request.

That is to say, in the embodiment shown in fig. 8, the RQ reference may also be replaced by the UE RQCapability, and it may also be implemented that the UE reports whether the UE supports RQ to the network side through the session procedure. Other steps are similar and will not be described herein.

The method for sending information according to the embodiment of the present application is described in detail above with reference to fig. 1 to 8. The method for sending the information provides an interactive process between a control plane and a user plane under an RQ mechanism.

Further, since the registration procedure is usually performed only once when the UE accesses the network, the UE reports to the network side whether the UE supports RQ through the registration procedure, which can reduce the signaling overhead of the UE side.

The communication apparatus according to the embodiment of the present application will be described with reference to fig. 9 and 14.
