Description

Technical Field

[0002] The goal of general quality of experience (QoE) is to collect user experience quality parameters for different service types. Among them, general QoE includes two configuration paths. One is signaling based, and its process is that the operation administration and maintenance (OAM) sends QoE configuration to the core network (CN), the core network sends QoE configuration to the RAN side, and the radio access network (RAN) side forwards QoE configuration to the terminal. In this case, the configuration is for a specific terminal; the other is management based, and its process is that OAM directly sends QoE configuration to the RAN side, and the RAN side forwards QoE configuration to the terminal. RAN visible QoE (RVQoE) measurement, that is, the QoE measurement report can be interpreted by the RAN side. At present, RAN visible QoE configuration must be performed after the terminal is configured with general QoE, based on the configurable service types and measurement indicators indicated by OAM.

[0003] When RVQoE is configured independently, that is, without the configuration content of common QoE, the configurable service type or configuration indicator of RVQoE cannot be delivered through the existing message content when the terminal moves. Summary of the invention

For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0122] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0123] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0124] In order to facilitate understanding of the solution of this application, the relevant contents involved in this application are first introduced.

[0125] 1. QoE measurement process

[0126] QoE measurement collects the quality of experience parameters of the service and also considers the typical performance requirements of different services, such as augmented reality (AR) / virtual reality (VR) and ultra-reliable low-latency communications (URLLC).

[0127] The protocol defines two types of QoE measurements: one is signaling based, in which OAM sends QoE configuration to the core network, the core network sends QoE configuration to the RAN side, and the RAN side forwards the QoE configuration to the terminal UE. In this case, the configuration is for a specific UE; the other is management based, in which OAM directly sends QoE configuration to the RAN side, and the RAN side forwards the QoE configuration to the UE. In this case, the configuration is currently performed for multiple UEs. In the system framework of the two measurement configurations based on signaling and management,

[0128] The process of QoE configuration sent by the RAN to the UE is the same, and the configuration parameters are also the same, and are all sent to the UE through Radio Resource Control (RRC) signaling.

[0129] The QoE measurement management parameters include but are not limited to the following parameters:

[0130] a) QoE collection entity address

[0131] This parameter is used to define the IP address to which the QoE Measurement Collection (QMC) records are to be transmitted. Either IPv4 or IPv6 addresses can be used.

[0132] b)QoE reference (QoEreference)

[0133] This parameter defines the identifier of the network requesting QoE measurement. QoEreference should be globally unique and can be composed of MCC+MNC+QMC ID. Among them, the Mobile Country Code (MCC) and Mobile Network Code (MNC) come from the management system and are used to define a Public Land Mobile Network (PLMN) included in the management system. The QMC ID is a 3-byte string.

[0134] c)QMC configuration file

[0135] This parameter defines the QoE profile defined by the application layer service.

[0136] d) Service Type

[0137] This parameter defines the service type for which QoE measurement is to be performed, including streaming media, Multimedia Telephony Service for IMS (MTSI), VR, etc.

[0138] e) Available RAN Visible QoE Metrics

[0139] Among them, RAN Visible QoE, referred to as RVQoE, is used to define the measurement indicators of configurable RVQOE.

[0140] After the UE's access stratum (AS) receives the QoE configuration through the RRC message, the AS layer will send the QoE configuration to the application layer through the command defined by ATcommand, which includes parameters such as Service Type, QoEreference, and QMC configuration file. When the service of the service type corresponding to the configuration begins to occur, the application layer begins to measure according to the configuration file and generates a measurement QoE report according to the configuration conditions. Once the QoE measurement report is generated, the UE's application layer sends the QoE report to the UE's AS layer through the AT command, and the UE's AS layer immediately sends the QoE to the RAN through an RRC message. The RAN sends the report to the server corresponding to the IP address defined in the configuration file. This completes the QoE configuration and measurement report collection process.

[0141] 2. RAN Visible QoE Measurement Process

[0142] When OAM configures UE normal QoE, OAM sends a measurement indicator indication to RAN that RVQOE can be configured. RAN configures visible QoE on this basis, and the configuration range is limited to the measurement indicator range indicated by OAM. RAN can send the RVQoE configuration to UE through the air interface RRC message together with the normal QoE. After that, the internal process of UE configuration is transmitted from the AS layer to the application layer like the normal QoE. The RVQoE report can also be sent to RAN together with the normal QoE report or sent to RAN separately. The RAN will not forward the RVQoE report received to the QoE report collection server, but will interpret and use it internally.

[0143] In the existing standard, the RVQoE configuration is generated by the base station control unit gNB-CU in the RAN and sent to the UE through RRC signaling. If the RVQoE configuration is generated by the base station distributed unit gNB-DU, the relevant information for generating the RVQoE configuration must be sent from the gNB-CU to the gNB-DU, and then the gNB-DU generates the RVQoE configuration based on this information and sends it to the gNB-CU; and the gNB-CU sends it to the UE through RRC signaling.

[0144] Currently, RAN visible QoE configuration must be performed after the terminal is configured with normal QoE, based on the configurable service types and measurement indicators indicated by OAM.

[0145] When RVQoE is configured independently, that is, without the configuration content of common QoE, the configurable service type or configuration indicator of RVQoE cannot be delivered through the existing message content when the terminal moves.

[0146] In order to solve the above-mentioned technical problems, the embodiments of the present application provide information transmission methods, devices, equipment and media, wherein the methods and devices are based on the same application concept. Since the principles of solving problems by the methods and devices are similar, the implementation of the devices and methods can refer to each other, and the repeated parts will not be repeated.

[0147] like Figure 1 FIG. 1 is a flow chart of an information transmission method provided in an embodiment of the present application. The method is applied to a first network node. The method may specifically include:

[0148] Step 101: Sending configuration information of a quality of experience (QoE) visible to a radio access network (RAN) to a second network node through first information, wherein the configuration information of the RAN QoE visible to the second network node is independently configured by the first network node; and the first information includes at least one of the following:

[0149] Switch request message;

[0150] Switch request message;

[0151] Restore terminal context response message.

[0152] Specifically, the configuration information of the RAN visible QoE is independently configured by the first network node for the terminal.

[0153] It should be noted that when a terminal is switched, or when the terminal moves from an inactive state (old network node) to a new network node and enters a connected state, step 101 is executed.

[0154] Before step 101, the first network node needs to first obtain the configuration information of the RAN visible QoE. To achieve this purpose, as an optional implementation, the method of the embodiment of the present application may further include:

[0155] Obtaining the service type or measurable indicator of the application established by the terminal through the core network equipment, operation and maintenance management OAM equipment or terminal;

[0156] The configuration information of the RAN visible QoE is independently configured for the terminal according to the service type of the application or the measurable indicator.

[0157] Optionally, the RAN-visible QoE configuration information is a RAN-visible QoE information parameter group; wherein the RAN-visible QoE information parameter group includes an applied service type and a RAN-visible QoE configuration identifier and at least one of the following information:

[0158] Measurable indicators;

[0159] RAN visible QoE configuration file.

[0160] The format of the configuration file of RAN visible QoE is an extensible markup language (XML) format or a parameter list format.

[0161] As an optional implementation, the above step 101 may include:

[0162] When the terminal is switched, the configuration information of RAN visible QoE is sent to the second network node through the switching requirement message and / or the switching request message; wherein the first network node is the source network node and the second network node is the target network node.

[0163] Here, the terminal switching may be a terminal switching based on NG, or a terminal switching based on Xn; different switchings correspond to different specific situations.

[0164] First, the steps in the implementation may specifically include:

[0165] When an NG-based handover occurs to the terminal, a handover request message is sent to an access mobility management AMF network element, where the handover request message carries the configuration information of the RAN visible QoE;

[0166] The AMF network element sends the switching request message to the first network node, and the switching request message carries the configuration information of the RAN visible QoE.

[0167] Here, when the terminal undergoes NG-based handover, the first network node (source network node) sends a handover requirement message, namely Handover Required, to the AMF network element. The handover requirement message carries the configuration information of RAN visible QoE.

[0168] Afterwards, after receiving the handover request message, the AMF network element obtains the configuration information of the RAN visible QoE; carries the configuration information of the RAN visible QoE in the handover request message, and returns the handover request message, namely HandoverRequest, to the first network node.

[0169] Optionally, both the switching requirement message and the switching request message include a first transparent container; wherein the configuration information of the RAN visible QoE is included in the first transparent container, and / or, in the QoE measurement collection configuration information of the first transparent container; the first transparent container is a transparent container from the source NG-RAN node to the target NG-RAN node.

[0170] Here, the first transparent container is a transparent container from the source NG-RAN node to the target NG-RAN node. It should be understood that the source NG-RAN node refers to the first network node and the target NG-RAN node refers to the second network node.

[0171] Embodiment 1: Transmission of RAN visible QoE configuration information during NG-based handover process

[0172] When the source RAN node independently configures the configuration information of RAN visible QoE, in order to configure relatively accurate measurement indicators, the source RAN node must at least obtain the service type or measurable indicator of the application established by the UE. Specifically, the source RAN node can obtain it from the core network device, OAM device or UE. Afterwards, the source RAN node independently configures the configuration information of RAN visible QoE for the UE according to the service type or measurable indicator. When the UE undergoes NG-based handover, in order to enable the target RAN node to independently configure RAN visible QoE more efficiently and accurately, the source RAN node transmits the RAN visible QoE information parameter group (i.e., the configuration information of RAN visible QoE) to the target RAN node through the handover requirement Handover Required message and the handover request HandoverRequest message in at least one of the following ways.

[0173] 1. Add the RAN visible QoE information parameter group to the QMC Configuration Information contained in the Source NG-RAN Node to Target NG-RAN Node Transparent Container.

[0174] 2. Included in the transparent container from the source NG-RAN node to the target NG-RAN node, add the RAN visible QoE information parameter group.

[0175] The RAN visible QoE information parameter group includes the service type of the application, the configuration identifier of the RAN visible QoE (such as RRC ID), and at least one of the following:

[0176] Measurable indicators;

[0177] RAN visible QoE configuration file.

[0178] Among them, the RAN visible QoE configuration file is in one of the following forms:

[0179] a) XML format;

[0180] b) Parameter list form.

[0181] See also Figure 2 , the specific information transmission process is as follows:

[0182] 1. The source RAN node sends a handover request message to the AMF network element, where the message includes the RAN visible QoE information parameter group, such as the service type of the application;

[0183] 2. The target RAN node receives the handover request message sent by the AMF network element, where the message includes the RAN visible QoE information parameter group, such as the service type of the application;

[0184] 2a. The target RAN node returns a handover request confirmation message to the AMF network element;

[0185] 1a. The AMF network element sends a handover command to the source RAN node;

[0186] 3. The target RAN node configures RAN visible QoE according to the RAN visible QoE information parameter group;

[0187] 4. The target RAN node sends the RAN visible QoE to the UE via an RRC message.

[0188] Alternatively, the steps in the implementation may specifically include:

[0189] When the terminal undergoes an Xn-based handover, the handover request message is sent to the second network node; wherein the handover request message includes QoE measurement collection configuration information; the configuration information of the RAN-visible QoE is included in the QoE measurement collection configuration information, and / or in the handover request message.

[0190] Here, QoE measurement collection is referred to as QMC.

[0191] Embodiment 2: Transmission of RAN Visible QoE Configuration Information during Handover Based on Xn

[0192] When the source RAN node independently configures the configuration information of RAN visible QoE, in order to configure relatively accurate measurement indicators, the source RAN node must at least obtain the service type or measurable indicator of the application established by the UE. Specifically, the source RAN node can obtain it from the core network device, OAM device or UE. After that, the source RAN node independently configures the configuration information of RAN visible QoE for the UE according to the service type or measurable indicator. When the UE undergoes an Xn-based handover, in order to enable the target RAN node to independently configure the RAN visible QoE more efficiently and accurately, the source RAN node transmits the RAN visible QoE information parameter group (i.e., the RAN visible QoE configuration information) to the target RAN node through a Handover Request in at least one of the following ways.

[0193] 1. Included in the QMC Configuration Information, add the RAN visible QoE information parameter group.

[0194] 2. In Handover Request, add the RAN visible QoE information parameter group.

[0195] The RAN visible QoE information parameter group includes the service type of the application, the configuration identifier of the RAN visible QoE (such as RRC ID), and at least one of the following:

[0196] Measurable indicators;

[0197] RAN visible QoE configuration file.

[0198] Among them, the RAN visible QoE configuration file is in one of the following forms:

[0199] a) XML format;

[0200] b) Parameter list form.

[0201] See also Figure 3 , the specific information transmission process is as follows:

[0202] 1. The source RAN node sends a handover request message to the target RAN node, which includes a RAN visible QoE information parameter group, such as the service type of the application;

[0203] 2. The target RAN node returns a handover request confirmation message to the source RAN node;

[0204] 3. The target RAN node configures RAN visible QoE according to the RAN visible QoE information parameter group;

[0205] 4. The target RAN node sends the RAN visible QoE to the UE via an RRC message.

[0206] As another optional implementation, the above step 101 may include:

[0207] When the terminal moves from an inactive state to the second network node and enters a connected state, the configuration information of RAN visible QoE is sent to the second network node through the restore terminal context response message; wherein the restore terminal context response message carries the configuration information of RAN visible QoE; the first network node is an old network node, and the second network node is a new network node.

[0208] Here, the first network node first receives a restore terminal context request message, ie, RETRIEVE UE CONTEXT REQUEST, sent by the second network node; then, the first network node returns a restore terminal context response message, ie, RETRIEVE UE CONTEXT RESPONSE, to the second network node.

[0209] Optionally, the restoring terminal context response message includes QoE measurement collection configuration information, and the RAN-visible QoE configuration information is included in the QoE measurement collection configuration information.

[0210] Example 3: Transmission of RAN Visible QoE Configuration Information during the Transition from Inactive to Connected State

[0211] When the old RAN node independently configures the configuration information of RAN visible QoE, in order to configure relatively accurate measurement indicators, the old RAN node must at least obtain the service type or measurable indicator of the application established by the UE. Specifically, the old RAN node can obtain it from the core network device, OAM device or UE. Afterwards, the old RAN node independently configures the configuration information of RAN visible QoE for the UE according to the service type or measurable indicator. When the UE enters the inactive state from the connected state, the UE's serving RAN node (i.e., the old RAN node) stores the UE context, which includes the service type or measurable indicator of the application established by the UE.

[0212] When the UE moves from the inactive state to the new RAN node, it enters the connected state. In order to enable the new RAN node to independently configure the RAN visible QoE more efficiently and accurately, when the new RAN node queries the old RAN node for UE context content, the old RAN node adds the RAN visible QoE information parameter group to the QMC ConfigurationInformation in the RETRIEVE UE CONTEXT RESPONSE message, and passes the RAN visible QoE information parameter group to the new RAN node.

[0213] The RAN visible QoE information parameter group includes the service type of the application, the configuration identifier of the RAN visible QoE (such as RRC ID), and at least one of the following:

[0214] Measurable indicators;

[0215] RAN visible QoE configuration file.

[0216] Among them, the RAN visible QoE configuration file is in one of the following forms:

[0217] a) XML format;

[0218] b) Parameter list form.

[0219] See also Figure 4 , the specific information transmission process is as follows:

[0220] 1. The old RAN node sends a restore terminal context request message to the new RAN node;

[0221] 2. The new RAN node sends a restore terminal context response message to the old RAN node, which includes a RAN visible QoE information parameter group, such as the service type of the application;

[0222] 3. The new RAN node configures RAN visible QoE according to the RAN visible QoE information parameter group;

[0223] 4. The new RAN node sends the RAN visible QoE to the UE via RRC messages.

[0224] The information transmission method of the embodiment of the present application sends the configuration information of the visible quality of experience QoE of the wireless access network RAN ​​to the second network node through the first information, wherein the configuration information of the visible QoE of the RAN is independently configured by the first network node; the first information includes at least one of the following: a switching requirement message; a switching request message; a terminal context recovery response message; in this way, the independently configured configuration information of the visible QoE of the RAN can realize content delivery between network nodes when the terminal moves through the above-mentioned first information.

[0225] like Figure 5 FIG. 1 is a flow chart of an information transmission method provided in an embodiment of the present application. The method is applied to a second network node. The method on the second network node side is as follows Figure 1 The method shown on the first network node side corresponds to the method executed by the opposite end.

[0233] Measurable indicators;

[0234] RAN visible QoE configuration file.

[0235] As an optional implementation, the above step 501 may include:

[0236] When the terminal switches, the configuration information of RAN visible QoE sent by the first network node is received through the switching requirement message and / or the switching request message; wherein the first network node is the source network node and the second network node is the target network node.

[0237] Here, the terminal switching may be a terminal switching based on NG, or a terminal switching based on Xn; different switchings correspond to different specific situations.

[0238] First, the steps in the implementation may specifically include:

[0240] The handover request message carries the configuration information of the RAN visible QoE;

[0241] The handover request message carries the configuration information of the RAN visible QoE.

[0242] Here, when the terminal undergoes NG-based handover, the first network node (source network node) sends a handover requirement message, namely Handover Required, to the AMF network element. The handover requirement message carries the configuration information of RAN visible QoE.

[0243] Afterwards, after receiving the handover request message, the AMF network element obtains the configuration information of the RAN visible QoE; carries the configuration information of the RAN visible QoE in the handover request message, and returns the handover request message, namely HandoverRequest, to the first network node.

[0244] Optionally, both the switching requirement message and the switching request message include a first transparent container; wherein the configuration information of the RAN visible QoE is included in the first transparent container, and / or, in the QoE measurement collection configuration information of the first transparent container; the first transparent container is a transparent container from the source NG-RAN node to the target NG-RAN node.

[0245] Here, the first transparent container is a transparent container from the source NG-RAN node to the target NG-RAN node. It should be understood that the source NG-RAN node refers to the first network node and the target NG-RAN node refers to the second network node.

[0250] Here, the second network node first sends a restore terminal context request message, ie, RETRIEVE UE CONTEXT REQUEST, to the first network node; then, the first network node returns a restore terminal context response message, ie, RETRIEVE UE CONTEXT RESPONSE, to the second network node.

[0251] Optionally, the restoring terminal context response message includes QoE measurement collection configuration information, and the RAN-visible QoE configuration information is included in the QoE measurement collection configuration information.

[0253] Configuring RAN visible QoE according to the configuration information of the RAN visible QoE;

[0254] Sending radio resource control RRC information to the terminal, where the RRC information includes the RAN visible QoE.

[0255] Specifically, after the AS layer of the terminal receives the RAN visible QoE through the RRC message, the AS layer sends the RAN visible QoE to the application layer through the command defined by the AT command. When the service of the corresponding service type starts to occur, the application layer starts to measure according to the configuration file and generates a RAN visible QoE measurement report according to the configuration conditions.

[0256] The information transmission method of the embodiment of the present application receives, through the first information, the configuration information of the wireless access network RAN ​​visible quality of experience QoE sent by the second network node, wherein the configuration information of the RAN visible QoE is independently configured by the first network node; the first information includes at least one of the following: a switching requirement message; a switching request message; a terminal context recovery response message; in this way, the independently configured RAN visible QoE configuration information can realize content delivery between network nodes when the terminal moves through the above-mentioned first information.
