In addition, the character "/" in this document indicates that the former and latter related objects are in an "or" relationship.

At least one of the embodiments of the present application refers to one or more. "plurality" means two or more. The descriptions of the first, second, etc. appearing in the embodiments of the present application are only for illustrating and differentiating the objects, and do not represent the order or the particular limitation of the number of the devices in the embodiments of the present application, and do not constitute any limitation to the embodiments of the present application. The term "connect" in the embodiments of the present application refers to various connection manners, such as direct connection or indirect connection, to implement communication between devices, which is not limited in this embodiment of the present application.

The embodiments of the present application may be applied to an NR communication system, a next generation wireless communication system, or the like, and are not limited by contrast. Fig. 1 is a diagram illustrating a network architecture of a communication system according to an embodiment of the present application. As shown, the communication system includes terminal 111, terminal 112, terminal 113, terminal 114, access point device 121, access point device 122, access point device 123, access network device 130, and core network device 140.

For example, the terminal 111 may communicate directly with the access network device 130. As another example, the terminal 112 may access the network through the access point device 121, and the access point device 121 is connected to the access network device 130. As another example, access point device 122 connects with access network device 130. In some embodiments, access point device 122 may also connect with core network device 140. Under the condition that the access point device 122 is connected to the access network device 130 and the core network device 140 at the same time, the core network device 140 may directly communicate with the access point device 122, or already communicate with the access point device 122 through the access network device 130, and a specific path through which the core network device 140 and the access point device 122 communicate may be preconfigured, or determined according to a certain policy, which is not limited herein. As another example, the access point device 123 is connected to the core network device 140.

Fig. 1 is merely an illustration of a communication system, which is not limited in the embodiments of the present application. For example, the number of access point devices, the number of terminals, the number of access network devices, the number of core network devices, and the like in the communication system are not limited in the embodiments of the present application.

A terminal in the embodiments of the present application may refer to various forms of UE, access terminal, subscriber unit, subscriber station, mobile station, MS (mobile station), remote station, remote terminal, mobile device, user terminal, terminal device (terminal equipment), wireless communication device, user agent, or user equipment. The terminal device may also be a cellular phone, a cordless phone, an SIP (session initiation protocol) phone, a WLL (wireless local loop) station, a PDA (personal digital assistant) with a wireless communication function, a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN (public land mobile network, chinese), and the like, which are not limited in this embodiment.

The access network device in the embodiment of the present application may be a device that provides an interface for a terminal or an access point device to access a communication network. For example, the access network device may be a base station, such as a 5G base station, a gnb (generation nodeb), or a base station in a next generation wireless communication system, which is not limited herein.

The access point device in this embodiment may provide a device for accessing an interface of an access network device or a core network device for the terminal. An example access point device may be an AP (access point), e.g., a 5G AP, h (e) NB, etc.

In one case, in NR (New Radio) mode, the UE receives a PDU SESSION ESTABLISHMENT request message during a PDU (Protocol Data Unit SESSION) SESSION activation, the PDU SESSION ESTABLISHMENT message includes Authorized QoS flow description IE (quality of service flow description authorization information element) and Authorized QoS rules IE (quality of service rule authorization information element), some of these Authorized QoS flow descriptors IE, Authorized QoS rules IE, or QoS rules have semantic syntax errors, and the UE needs to send PDU SESSION MODIFICATION REQUEST carrying the reason of #83 "semantic error in the QoS operation" or #84 "semantic error in the QoS operation" to the network to delete QoS flow descriptors, QoS rules (QoS flow descriptors, QoS rules may occur simultaneously or any one of them may occur).

In another case, in NR mode, the UE receives a PDU SESSION MODIFICATION COMMAND message during PDU SESSION MODIFICATION, where the PDU SESSION MODIFICATION COMMAND message includes Authorized QoS flow description IE, Authorized QoS rules IE, some of which have semantic syntax errors or QoS rules, and the UE needs to send PDU SESSION MODIFICATION REQUEST to the network to delete these QoS flow description, QoS rules (QoS flow description, QoS rules may occur simultaneously or may occur at any time).

In the above two cases, the QoS flow description and QoS rules of the UE and the network device (which may be a base station or an access point device) are not consistent, and the inconsistency of the QoS flow description and QoS rules may cause the network device to have an error when selecting the downlink of the UE, for example, the Authorized QoS flow description IE 1 and the Authorized QoS rules IE 1 have an error, and the network device selects the downlink corresponding to the Authorized QoS flow description IE 1 and the Authorized QoS rules IE 1, which may cause a communication failure of the downlink and affect the communication quality.

In order to solve the communication failure, the present application provides a QoS association information synchronization method, which may be implemented under the communication framework shown in fig. 1, and for convenience of description, the present application refers to a terminal as a UE, and refers to an access point device, an access network device, and a core network device as a network device, and the method, as shown in fig. 2, includes the following steps:

step S200, the network device sends PDU Session initiation ACCEPT or PDU Session MODIFICATION COMMAND to the UE.

Step S201, when the UE detects the QoS semantic syntax error in PDU Session initiation accepted or PDU Session MODIFICATION COMMAND, it sends PDU Session MODIFICATION REQUEST to the network device;

step S202, when the UE determines that the PDU Session MODIFICATION REQUEST is sent abnormally, the UE sends a REGISTRATION REQUEST to the network device, and the REGISTRATION REQUEST carries QoS correlation information.

The REGISTRATION REQUEST may be a REGISTRATION REQUEST in REGISTRATION update (REGISTRATION update).

For example, as shown in Table 1, the contents of a REGISTRATION REQUEST provided for the present application.

Table 1:

where XX in IE indicates the newly added content in the REGISTRATION REQUEST.

The contents of the QoS flow descriptions status IE are shown in Table 2:

table 2:

the content of PDU session identity is shown in table 3:

table 3:

the contents of the QoS rules status IE are shown in Table 4:

table 4:

the sending exception includes any one of the following:

failure of the underlying transmission, transmission timeout (e.g., T3581 timeout), receipt of an indication that PDU Session MODIFICATION REQUEST cannot be forwarded.

The QoS related information may be information corresponding to a QoS semantic syntax error, and may include any one or any combination of the following information:

the QoS flow describes QoS flow descriptors and QoS rules.

For example, in an example, if syntax errors occur in the Authorized QoS flow description IE 1 and Authorized QoS rules IE 1 in the PDU SESSION ESTABLISHMENT access ACCEPT, the QoS association information may specifically be: QoS flow description IE 1 and QoS rules IE 1.

Step S203, the network device deletes the QoS association information carried according to the REGISTRATION REQUEST.

In the above-mentioned scheme, the combination of step S200 and step S203 may be implemented by the network device, and the combination of step S201 and step S202 may be implemented by the user device.

According to the technical scheme, when syntax errors occur in QoS (quality of service) associated information carried by PDU (protocol data Unit) SESSION update ACCEPT or PDU SESSION update COMMAND, a PDU SESSION update REQUEST is sent to the network equipment firstly, but when the PDU SESSION update REQUEST is abnormal (for example, overtime and the like), a REGISTRATION REQUEST is sent to the network equipment, and the network equipment deletes the QoS associated information according to the REGISTRATION REQUEST, so that the consistency of the QoS associated information is kept, the possibility of downlink communication failure is reduced, and the network performance is improved.

Example one

An embodiment of the present application provides a method for synchronizing QoS (quality of service) association information, where the method is executed under a network architecture shown in fig. 1, and the method is shown in fig. 3, and includes the following steps:

step S300, in the NR mode, the UE sends a PDU SESSION ESTABLISHMENT REQUEST to the network to initiate a procedure for PDU SESSION (PDU SESSION ID ═ 1).

Step S301, the UE receives a PDU Session ESTABLISHMENT response message from the network.

The PDU SESSION ESTABLISHMENT response message carries Authorized QoS flow description IE and Authorized QoS rules IE. For example, in an alternative scheme, the Authorized QoS flow description IE includes two QoS flow descriptions: QFI 1, Operation code, Create new QoS flow description, including all necessary parameters; QFI 2, Create new QoS flow description, lacking MFBR uplink and MFBR downlink parameters. The Authorized QoS rules contain two QoS rules: QoS rule 1 QRI 1, DQR bit: 1, QFI 1, Operation code ═ Create new QoS rule; QoS rule2 QRI 2, DQR bit: 0, QFI 2, Operation code ═ Create new QoS rule.

QFI 1 in QoS rule 1 indicates that QoS rule 1 is associated with QFI 1, and QFI 2 in QoS rule2 indicates that QoS rule2 is associated with QFI 2.

Since the second QoS flow description lacks the necessary MFBR uplink and MFBR downlink parameters, the UE needs to send PDU SESSION MODIFICATION REQUEST for #84 reason to delete this QoS flow description and the associated QoS rule.

Step S302, the UE sends PDU Session MODIFICATION REQUEST (carrying QFI 2 QoS flow descriptions and QFI 2 QoS rule).

This PDU SESSION MODIFICATION REQUEST for deleting QoS flow description and QoS rule is not successfully sent to the network for some reasons, and this embodiment takes as an example that when the T3581 timer continuously times out for 4 times, none of the REQUESTs are successfully sent to the network, and certainly in practical application, the REQUESTs may also be in other manners that the REQUESTs are not successfully sent to the network.

Step S303, after the PDU session modification procedure is finished, the UE notifies the network through the REGISTRATION update procedure: QoS flow descriptors and QoS rule state of UE side.

According to the technical scheme provided by the application, when grammar error occurs in QoS associated information carried by PDU SESSION ESTABLISHMENT ACCEPT, a REGISTRATION REQUEST is sent to the network equipment at first, but when the REGISTRATION REQUEST is sent abnormally (for example, overtime, and the like), the REGISTRATION REQUEST is sent to the network equipment, and the network equipment deletes the QoS associated information according to the REGISTRATION REQUEST, so that the consistency of the QoS associated information is maintained, the possibility of downlink communication failure is reduced, and the network performance is improved.

Based on the same concept, an embodiment of the present application provides a quality of service QoS correlation information synchronization apparatus, as shown in fig. 4, the apparatus is applied to a user equipment, and the apparatus includes:

a communication unit 401, configured to receive a PDU SESSION ESTABLISHMENT acceptance ACCEPT message or a PDU SESSION MODIFICATION COMMAND message sent by a network device;

a processing unit 402, configured to determine that a SESSION MODIFICATION REQUEST PDU SESSION MODIFICATION REQUEST for deleting QoS related information is sent abnormally when a QoS semantic syntax error is detected and the QoS related information needs to be deleted; controlling the communication unit to send a REGISTRATION REQUEST carrying a QoS associated information identifier to the network equipment;
