[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] The term "comprise" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to the process, method, product, or apparatus. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and both A and B are included.

[0054] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0055] In related technologies, the following solutions are usually used to implement local offload at the base station side:

[0056] Solution 1: Determine the transmission strategy for local downlink services based on the transmission strategy for local uplink services. However, since there are no dedicated QoS rules configured for local uplink services, terminals (e.g., user equipment (UE)) typically map local service flows to the corresponding QoS flows in the default QoS rules and transmit them using the default QoS rules. In this scenario, the quality of service for local services cannot be guaranteed, and differentiated QoS guarantees cannot be provided for local service flows of different priorities.

[0057] Solution 2: Using a customized process, the base station initiates a configuration request for QoS parameters corresponding to a new QoS flow to the core network for local service flows, thereby establishing different logical transmission channels for different local services. Solution 2 involves many network elements (for example, the base station, session management function (SMF), access and mobility management function (AMF), UPF, etc.), making it difficult to implement.

[0058] Solution 3: Configure a 5G QoS identifier (5QI) for local services on the base station side and adopt differentiated air interface scheduling strategies for different 5QIs. However, this solution 2 can only be used to solve the QoS policy control problem of the access layer (AS) and cannot take into account the processing process of the UE non-access layer (NAS). Therefore, it cannot achieve true end-to-end differentiated QoS strategy.

[0059] See also Figure 2 An embodiment of the present application provides a communication processing method, which is executed by a wireless access network device, which may be a base station. The specific steps include: step 201 and step 202.

[0060] Step 201: Acquire a QoS flow of first data sent by a terminal and a QoS flow identifier (QoS Flow Identifier, QFI) of the QoS flow;

[0061] In this embodiment, the QFI is allocated by the terminal side and is sent to the radio access network device by being mapped to the first radio bearer.

[0062] For example, terminals may be randomly assigned QFIs.

[0063] For another example, the terminal may also allocate QFI according to preset rules, which include but are not limited to at least one of the following: 1) Based on service type, that is, QFI can be allocated according to the service type to which the service flow belongs, which helps to distinguish and process various transmission requirements such as audio, video or ordinary data transmission. This method enables the corresponding data flow to obtain network resources and priorities that match its service type; 2) Based on flow sequence number, that is, QFI can be allocated according to the flow sequence number of the data, which is suitable for scenarios where further priority or characteristics need to be divided within the same type of service, and allows fine-grained control of differentiated processing between similar data flows.

[0064] It is understandable that the QFI allocated to the terminal is different from the existing QFI of the non-local service allocated by the core network and notified to the terminal.

[0065] In this embodiment, the first data sent by the terminal received in step 201 meets the diversion rule of the local service flow. Optionally, the diversion rule includes a five-tuple, namely, the source port number, the destination port number, the protocol number, the source IP address, and the destination IP address. Furthermore, the diversion rule may also include: a slice identifier or a Public Land Mobile Network (PLMN) or a Domain Name System (DNS).

[0066] Optionally, in step 201, the QoS flow of the first data is parsed through the Service Data Adaptation Protocol (SDAP) layer of the radio access network device to obtain the QFI.

[0067] Step 202: When the first data meets the diversion rules of the local business flow, the QoS flow of the first data is carried on the default (Default) wireless bearer, the wireless access network device cannot identify the QFI, and the QoS flow of the first data matches the QoS parameters locally configured by the wireless access network device, a first message is sent to the terminal, where the first message is used to indicate the first wireless bearer, the first wireless bearer is used to carry the QoS flow of the first data, and the first wireless bearer is associated with the QFI of the QoS flow of the first data.

[0068] That is, for the initial first data transmission, the new QFI is mapped to the default radio bearer. After the radio access network device updates the mapping relationship between the QFI and the first radio bearer, the QoS flow of the first data is subsequently mapped to the first radio bearer for transmission.

[0069] Optionally, the radio bearer in this application may be referred to as a data radio bearer (DRB) or an air interface transmission bearer.

[0070] The QoS flow of the above-mentioned first data matches the QoS parameters locally configured by the wireless access network device, which can be understood as the wireless access network device can identify the QoS flow of the first data based on the locally configured QoS parameters. For the QoS flow of the first data that is successfully identified, the wireless access network device establishes or modifies one or more dedicated wireless bearers for one or more QoS flows of the first data.

[0071] Optionally, the first message may further indicate that the first radio bearer is determined by creating a new radio bearer or modifying an existing radio bearer.

[0072] The above-mentioned method of modifying the original wireless bearer to determine the first wireless bearer means that the wireless access network device reuses the original wireless bearer and modifies the parameters of the original wireless bearer, such as adding the correspondence between the original wireless bearer and the QFI, that is, the QoS flow of the first data is carried by the original wireless bearer after the parameter modification.

[0073] In this embodiment, when the wireless access network device cannot identify the QFI, the wireless access network device does not discard the first data that is not identified by the QFI. If the QoS bearer of the first data is on the default wireless bearer, packet matching is performed to identify different QoS flows, and a first message is sent to the terminal based on the QoS parameters of the QoS flow of the first data. Furthermore, the first message may carry first information, and the first information is used to indicate that one or more first wireless bearers are obtained by creating or modifying a wireless bearer. Further, the first message may also carry second information, and the second information is used to indicate the association relationship between the first wireless bearer and the QFI of the QoS flow of the first data.

[0074] The above-mentioned first message may include an RRC reconfiguration message.

[0075] The first radio bearer may also be referred to as a dedicated radio bearer.

[0076] In an embodiment of the present application, before or after sending the first message to the terminal, the method may further include: storing a mapping relationship between the QFI of the QoS flow of the first data and the QoS parameters locally configured in the radio access network device.

[0077] Optionally, a set of QoS parameters may include but is not limited to at least one of the following: one or more QoS rules (QoSrule), QoS configuration, etc.

[0078] Optionally, the QoS rule may include but is not limited to at least one of the following: a packet filter set, a priority, and the like.

[0079] Optionally, the QoS configuration may include but is not limited to at least one of the following: 5G QoS identifier (5GQoSIdentifier, 5QI), allocation and retention priority (ARP), reflective QoS attribute (RQA), guaranteed flow bit rate (Guaranteed Flow Bit Rate, GFBR), maximum flow bit rate (Maximum Flow Bit Rate, MFBR), aggregate maximum bit rate (AggregateMaximum Bit Rate, AMBR), etc.

[0080] In one embodiment of the present application, the QoS parameters of the first data can be used to configure at least one of the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Physical Layer (PHY) layer of the wireless access network device.

[0081] In one embodiment of the present application, before or after sending the first message to the terminal, the method further includes:

[0082] If the QoS parameters of the QoS flow on the established second radio bearer are exactly the same as the QoS parameters of the QoS flow of the first data, the parameters of the second radio bearer are modified, and the first radio bearer reuses the modified second radio bearer.

[0083] It is understandable that the conditions for determining whether the second radio bearer can be reused may include but are not limited to: whether the QoS parameters corresponding to the QFI of the QoS flow of the first data are the same as the QoS parameters corresponding to the second radio bearer.

[0084] Optionally, before or after sending the first message to the terminal, the radio access network device may establish a modified mapping relationship between the second radio bearer and the QFI.

[0085] It is understandable that the second radio bearer is a radio bearer used to carry a QoS flow for other service data, and the QoS parameters of the QoS flow on the second radio bearer are not local QoS parameters of the radio access network device. In this embodiment, the parameters of the second radio bearer are modified so that the modified second radio bearer can be used as a radio bearer for carrying a QoS flow for the first data, that is, the original second radio bearer is reused to carry the QoS flow for the first data.

[0086] In one embodiment of the present application, before or after sending the first message to the terminal, the method further includes:

[0087] If the radio bearer corresponding to the QoS parameters locally configured by the radio access network device is not established, or the existing radio bearer cannot be reused, the first radio bearer is determined by creating a new radio bearer.

[0088] In one embodiment of the present application, the first data corresponds to one or more QoS flows, and each QoS flow corresponds to a set of QoS parameters. In one embodiment of the present application, before or after step 201, the method further includes:

[0089] Obtain the diversion rules and / or QoS parameters of the local service flow.

[0090] For example, the diversion rules and / or QoS parameters of the local service flow configured by the wireless network management or local operation and maintenance tool are obtained. It can be understood that the specific number of diversion rules and QoS parameters is not limited in this embodiment.

[0091] Optionally, the wireless access network device sends the QoS parameters of the QoS flow of the first data to the terminal through an application layer custom message.

[0092] In one embodiment of the present application, before or after sending the first message to the terminal, the method further includes:

[0093] receiving second data;

[0094] Mapping the second data to one or more QoS flows, where the QoS flow corresponds to one of the QFIs;

[0095] According to the correspondence between the first radio bearer and the QFI, one or more QoS flows are mapped to the corresponding first radio bearer, and the second data is sent to the terminal through the first radio bearer.

[0096] For example, the wireless access network receives the second data (i.e., downlink local service data) from the local data network (Local DN), matches the corresponding one or more QoS flows according to the packet filter set, and maps the one or more QoS flows to the first wireless bearer according to the correspondence between the first wireless bearer and the QFI.

[0097] In one embodiment of the present application, before or after sending the first message to the terminal, the method further includes:

[0098] A business requirement for obtaining the first data;

[0099] According to the service requirements of the first data, it is determined whether to release the first radio bearer corresponding to the QFI.

[0100] For example, if the radio access network device fails to detect the first data within a period of time, it may initiate an RRC reconfiguration process to release the first radio bearer newly created for the first data, or, if the first radio bearer reuses an existing radio bearer (such as the second radio bearer described above), modify the existing radio bearer to de-associate the QFI of the QoS of the first data, thereby achieving dynamic dedicated bearer release for the first data.

[0101] In the present application, the wireless access network device can allocate a dedicated first wireless bearer for the QoS flow of the first data by creating a new wireless bearer or modifying the original wireless bearer. In this way, in the wireless access network device diversion scenario, the wireless access network device can provide differentiated QoS guarantee services for different service types.

[0102] See also Figure 3 , an embodiment of the present application also provides a communication processing method, which is executed by a terminal, and the specific steps include: step 301 and step 302.

[0103] Step 301: Send a QoS flow of first data and a QFI of the QoS flow through a default radio bearer, where the QFI is allocated by the terminal;

[0104] It should be noted that the QoS flow in step 301 is a newly configured QoS flow (ie, a QoS flow with a non-default QoS rule). Since the QoS flow is not associated with a radio bearer, it is sent through the default radio bearer.

[0105] Step 302: Receive a first message, where the first message is used to indicate a first radio bearer, the first radio bearer is used to carry the QoS flow of the first data, and the first radio bearer is associated with the QFI of the QoS flow of the first data;

[0106] Among them, the first message is sent by the wireless access network device when the first data meets the diversion rules of the local service flow of the wireless access network device, the wireless access network device cannot identify the QFI, and the QoS flow of the first data matches the QoS parameters locally configured by the wireless access network device.

[0107] Optionally, the first message is further used to indicate that the first radio bearer is determined by the radio access network device by creating a new radio bearer, or to indicate that the first radio bearer is determined by the radio access network device by modifying an existing radio bearer.

[0108] In one embodiment of the present application, before sending the QoS flow of the first data and the QFI of the QoS flow through the default radio bearer, the method further includes:

[0109] The QoS parameters of the QoS flow of the first data are obtained by local configuration.

[0110] For example, through the AT (Attention) command, the QoS parameters of the QoS flow of one or more first data input by the operator are obtained, and the configuration values ​​of the QoS parameters obtained through local configuration are consistent with the parameter values ​​of the QoS parameters configured on the wireless access network device side. For example, calling the AT command: +CGDSCONT to create a non-default QoS flow, +CGTFT to set the traffic template (Traffic Flow Template, TFT) parameters for the QoS flow, and +C5GQOS to configure the QoS parameters of the QoS flow.

[0111] In another embodiment of the present application, before sending the QoS flow of the first data and the QFI of the QoS flow through the default radio bearer, the method further includes:

[0112] The QoS parameters of the first data are obtained by means of network side configuration.

[0113] For example, through a custom application layer message, the QoS parameters configured by the wireless access network device for the QoS flow of the first data are notified to the UE. The UE application layer identifies and parses the parameters, and automatically calls the AT command interface through software to configure the parameters to the UE non-access stratum (NAS) layer. In this way, the UE side establishes one or more QoS flows for the first data, corresponding to different QoS parameters (non-default QoS rules).

[0114] In one embodiment of the present application, after receiving the first message, the method further includes:

[0115] According to the correspondence between the first wireless bearer and the QFI of the QoS flow of the first data, the QoS flow of the first data (for example, local uplink service data) is mapped to the first wireless bearer, and the first data is sent to the wireless access network device through the first wireless bearer.

[0116] For example, for local uplink services, the terminal filters and matches the QoS flow according to the configured QoS parameters and assigns a QFI to it. The UE maps the new QFI to the default radio bearer for the initial uplink transmission according to the mapping rules of the QFI and radio bearer configured by the network-side device. After the network-side device updates the radio bearer mapping relationship for the QFI through the first message, the QoS flow of the local uplink service is subsequently mapped to the newly established or modified dedicated radio bearer (i.e., the first radio bearer) for transmission, so as to achieve hierarchical transmission according to QoS.

[0117] This embodiment provides a method for establishing a dedicated air interface radio bearer for the QoS flow of first data and mapping the QoS flow of the first data to the dedicated radio bearer, thereby solving the problem of providing a differentiated QoS guarantee mechanism for the first data. Compared with the solution of modifying the Protocol Data Unit (PDU) session at the NAS layer, this solution only involves modifications on the radio access network side, but its application scope also covers the UE NAS layer, making it easier to implement and promote.

[0118] See also Figure 4 , the specific steps are as follows:

[0119] Step 401: The base station configures QoS parameters and diversion rules for first data (eg, local service data).

[0120] For example, the base station configures one or more sets of QoS parameters and one or more diversion rules for the first data through an external network management or a local operation and maintenance tool.

[0121] Optionally, the diversion rule for the local service flow may include a five-tuple, namely the source port number, destination port number, protocol number, source IP address, and destination IP address. Furthermore, the diversion rule may also include: a slice identifier or a Public Land Mobile Network (PLMN) or a Domain Name System (DNS).

[0122] Optionally, a set of QoS parameters may include but is not limited to at least one of the following: one or more QoS rules (QoSrule), QoS configuration, etc.

[0123] Optionally, the QoS rule may include but is not limited to at least one of the following: a packet filter set, a priority, etc.

[0124] Optionally, the QoS configuration may include at least one of the following: 5G QoS Identifier (5QI), Allocation and Retention Priority (ARP), Reflective QoS Attribute (RQA), Guaranteed Flow Bit Rate (GFBR), Maximum Flow Bit Rate (MFBR), Aggregate Maximum Bit Rate (AMBR), etc.

[0125] Optionally, 5QI may include at least one of the following: latency, packet loss rate, service priority, etc.

[0126] In this embodiment, the terminal side can configure the same QoS parameters as the base station side for the first data. There are two optional configuration methods, namely step 402 and step 403.

[0127] Step 402 (method 1): The UE configures one or more sets of QoS parameters through AT commands.

[0128] For example, call the AT command: +CGDSCONT to create a non-default QoS flow, +CGTFT to set TFT parameters for the QoS flow, and +C5GQOS to configure one or more sets of QoS parameters for the QoS flow.

[0129] It can be understood that the configuration values ​​of the QoS parameters of the one or more first data QoS flows configured by the UE in step 402 should be consistent with the configuration values ​​of the QoS parameters of the first data QoS flows on the base station side.

[0130] Step 403 (Mode 2): The base station sends one or more sets of QoS parameters to the UE.

[0131] For example, the base station assembles a custom message of the application layer, and sends the custom message to the terminal. The custom message carries one or more sets of QoS parameters configured for one or more first data.

[0132] For example, the UE identifies the received custom message and parses one or more sets of QoS parameters sent by the base station. The software automatically calls the interface of the AT command and configures them to the UE non-access stratum (NAS) layer. In this way, the UE side establishes one or more QoS flows for the first data, and different QoS flows correspond to different QoS parameters (for example, QoS parameters associated with non-default QoS rules).

[0133] It should be noted that one or both of step 402 and step 403 may be performed, i.e., the terminal may obtain QoS parameters consistent with those on the base station side in at least one of the two ways. It is understood that if steps 402 and 403 need to be performed, the order of steps 402 and 403 is not limited, i.e., step 402 may be performed first, then step 403, or step 403 may be performed first, then step 402, or both steps 402 and 403 may be performed simultaneously.

[0134] Step 404: The UE filters and matches the QoS flow according to the QoS parameters configured in step 402 and / or step 403, matches the newly configured QoS flow (QoS flow associated with non-default QoS rules), and allocates QFI, and sends the QoS flow of the first data and the QFI of the QoS flow to the base station through the default wireless bearer.

[0135] Because the newly configured QoS flow is not associated with a radio bearer, only the default radio bearer can be used.

[0136] Step 405: The base station Service Data Adaptation Protocol (SDAP) layer does not discard the first data that is not identified by the QoS Flow Identifier (QFI). The diversion module identifies the first data according to the diversion rules. If it is carried on the default DRB, packet matching is performed to identify different QoS flows, and the air interface reconfiguration process is triggered on demand according to the QoS parameters corresponding to each QoS flow, which is used to create or modify one or more dedicated DRBs, store and notify the UE to update the mapping rules between local service QoS flows and DRBs.

[0137] The QFI may be obtained by parsing the first data by the SDAP layer of the base station, that is, allocated and carried by the UE side.

[0138] In this embodiment, after the diversion module diverts the first data according to the diversion rules, for the first data that meets the diversion rules and is carried on the default radio bearer and carries an unidentified QFI, packet filtering is performed according to the configuration in step 401 to match the QoS flow and the corresponding QoS parameters (QoS parameters corresponding to non-default QoS rules). For one or more first data that are successfully matched, one or more corresponding dedicated radio bearers are established or modified for the first data, a correspondence between the QFI and the dedicated radio bearer is established, and the dedicated radio bearer is used for transmission. There are two optional methods:

[0139] (1) If the second radio bearer corresponding to the QoS parameters (e.g., 5QI) configured locally by the base station has been established, and the QoS parameters of the QoS flow of the first data are exactly the same as the QoS parameters of the original QoS flow on the second radio bearer, the original second radio bearer can be reused, an air interface reconfiguration process can be initiated, the second radio bearer parameters can be modified, and the QFI corresponding to the second radio bearer can be added;

[0140] (2) If the wireless bearer corresponding to the QoS parameters (e.g., 5QI) configured locally by the base station is not established, or the original wireless bearer cannot or does not want to be reused, one or more new wireless bearers may be initiated to establish, and the QoS parameters of the QoS flow of the first data are associated therewith. Based on this, the parameter configuration of each layer on the wireless side is determined, and the SDAP or Packet Data Convergence Protocol (PDCP) or Radio Link Control (RLC) or Media Access Control (MAC) or Physical Layer (PHY) of the base station and UE are configured respectively.

[0141] Step 406: The base station sends an RRC reconfiguration message to the UE, where the RRC reconfiguration message is used to indicate that a first radio bearer is determined by creating a new radio bearer or modifying an existing radio bearer, where the first radio bearer is used to carry the QoS flow of the first data, and the first radio bearer is associated with the QFI of the QoS flow of the first data.

[0142] Optionally, the RRC reconfiguration message includes first information and second information, the first information is used to indicate that the first wireless bearer is determined by creating a new wireless bearer or modifying the original wireless bearer, and the second information is used to indicate the correspondence between the QoS flow of the first data and the first wireless bearer.

[0143] Optionally, if the base station fails to detect a certain first data for a period of time, it may initiate an RRC reconfiguration process to release the first radio bearer newly created for the uplink data, or, if the QoS flow of the first data and the QoS flow of other service data multiplex a second radio bearer, modify the second radio bearer to de-associate the QFI of the service flow, thereby achieving dynamic dedicated bearer establishment and release for the first data.

[0144] Step 407: The UE sends an RRC reconfiguration complete message.

[0145] Step 408: The base station receives first data from the local data network;

[0146] Step 409: The base station matches the corresponding QoS flow according to the QoS parameters, and maps different QoS flows to different first radio bearers for air interface transmission according to the QFI.

[0147] Step 410: The base station performs second data transmission through the first radio bearer.

[0148] Step 411: During uplink transmission, the UE filters according to the configured QoS parameters and maps to the newly configured QoS flow (the QoS flow of the non-default QoS rule). The previously allocated QFI is used. At this time, according to the latest configuration (the correspondence between the first radio bearer and the QFI), the QoS flow of the first data can be mapped to the first radio bearer determined by the newly established or modified radio bearer mode.

[0149] Step 412: The UE performs first data transmission through the first radio bearer.
