It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0181] 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.

[0182] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.

[0183] 1. QoE measurement

[0184] The protocol defines two types of QoE measurements. One is signaling based, in which the operation administration and maintenance (OAM) sends QoE configuration to the core network (CN), the core network sends QoE configuration to the radio access network (RAN), and the RAN forwards the QoE configuration to the UE. In this case, the configuration is for a specific UE. The other is management based, in which the OAM directly sends QoE configuration to the RAN, and the RAN forwards the QoE configuration to the UE. In this case, the configuration is for multiple UEs. In the system framework of the two measurement configurations of signaling based and management based, 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 sent to the UE through radio resource control (RRC) signaling. Signaling based measurements are generally used for measurement collection of specified users, and management based measurements are generally used for measurement collection of specified areas.

[0185] The protocol defines the Quality of Experience (QoE) measurement management parameters, including the following parameters (the following parameters are exemplary and not all are listed):

[0186] a)QoE collection entity address

[0187] This parameter is used to define the Internet Protocol (IP) address to which the QoE Measurement Collection (QMC) records will be transmitted. Either Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6) addresses can be used.

[0188] b)QoEreference

[0189] This parameter defines the identifier of the network requesting QoE measurement. QoEreference should be globally unique, so it consists of the following: Mobile Country Code (MCC) + Mobile Network Code (MNC) + QMC Identifier (ID), where MCC and 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.

[0190] c)QMC configuration file

[0191] This parameter defines the QoE profile defined by the application layer service.

[0192] d)Service Type

[0193] This parameter defines the service type for which QoE measurement is to be performed, including streaming media, Multimedia Telephony Service for IMS (IP Multimedia Subsystem), MTSI, and Virtual Reality (VR).

[0194] 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 the AT (Attention) instruction, including 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 QoE measurement report according to the configuration conditions. Once the QoE measurement report is generated, the UE's application (APP) layer sends the QoE measurement report to the UE's AS layer through the AT command, and the UE's AS layer sends the QoE measurement report to the RAN through the RRC message. The RAN sends the QoE measurement report to the corresponding server corresponding to the IP address defined in the configuration file, thereby completing the QoE configuration and measurement report collection process.

[0195] The base station can also configure the base station visible QoE, that is, RVQoE (RANvisiable QoE), based on the QoE configured by the above OAM. Because the ordinary QoE measurement report is mainly used by OAM and encoded in the format defined by OAM, the base station does not decode the QoE measurement report in principle; if the base station also intends to improve and guarantee QoE, it can configure the UE to report RVQoE, so that the base station can directly receive and use RVQoE.

[0196] 2. MBS business

[0197] Currently, most of the communications between the network and UE are in the form of ordinary unicast, that is, one-to-one. In order to support one-to-many communication and save network resource consumption, multicast and broadcast methods are introduced.

[0198] For multicast services, the same service and content are provided to a specified group of users at the same time. UE can receive multicast services in the connected state, and will support receiving multicast services in the inactive state in the future. For base stations that support multicast, the base station may use a set of common resources to provide services to a specific group of UEs. When the UE switches to a base station that does not support multicast, it cannot establish an MBS radio bearer (MBS Radio Bearer, MRB), and can only continue to provide services through the UE-specific data radio bearer (Data Radio Bearer, DRB), that is, to deliver multicast service content in a unicast manner.

[0199] For broadcast services, the same services and content are provided to all UEs in a specific area. UEs can receive broadcast services in idle, inactive or connected states. When UEs move in a connected state, the continuity of UE broadcast services needs to be guaranteed, and cells that support the same services need to be selected as target cells.

[0200] Base stations can exchange information about the support of multicast and broadcast in adjacent cells through interfaces, including whether broadcast and / or multicast are supported and the specific service type. The service type can be identified by a temporary mobile group identity (TMGI) or a service area identity (SAI).

[0201] The UE can receive broadcast services in idle or inactive states. Because cell reselection in idle state also needs to consider selecting cells that support broadcast services as much as possible, if the UE is receiving a broadcast service or intends to receive a broadcast service, the cell reselection frequency priority can be set to high priority.

[0202] 3. Base station prediction function

[0203] The base station predicts the future services of the UE, which is used by the base station to guarantee the service needs of the UE in advance. The current prediction results are mainly service types and related measurement indicators. The QoE and / or RVQoE measurement indicators corresponding to the UE services can be further predicted to better reflect the customer's experience. The specific UE predicted QoE and / or RVQoE indicators include at least one of the following:

[0204] (1) Types of services that the UE will perform in the future.

[0205] (2) Time information corresponding to the service type, that is, the time period in which the UE will perform the service.

[0206] (3) The probability that the UE will perform the service, that is, the accuracy of the prediction.

[0207] (4) QoE and / or RVQoE measurement indicators of the service performed by the UE. The QoE and / or RVQoE indicators predicted by the base station may include all measurement indicators supported by the service, or may include some measurement indicators, based on the capabilities.

[0208] The base station predicts the future trajectory of the UE and can further predict the QoE and / or RVQoE measurement indicators corresponding to the UE service at the corresponding location. The specific UE predicted QoE and / or RVQoE indicators include at least one of the following:

[0209] (1) Future UE trajectory information.

[0210] (2) Time information corresponding to the UE location.

[0211] (3) The probability that the UE moves to that location, that is, the accuracy of the location prediction.

[0212] (4) QoE and / or RVQoE measurement indicators corresponding to the services performed by the UE at this location. The QoE and / or RVQoE measurement indicators may include all possible services, or may only include services that the base station predicts the UE may perform. The specific predicted QoE and / or RVQoE indicators may include all measurement indicators, or may include some measurement indicators.

[0213] The base station can predict user load, user service, and user trajectory for user energy saving, load balancing, and mobility optimization. Based on the user service prediction, the base station can further predict the QoE index of the corresponding service, and based on the user trajectory prediction, the QoE index of the corresponding location can be further predicted. For users in the connected state, when triggering a handover, the base station can send the above prediction results to the handover target base station for the target base station to ensure QoE. However, for terminals receiving MBS services, the terminals can receive MBS services in an idle state or an inactive state. At this time, the mobility is controlled by the terminal, and the network cannot trigger the handover process. Therefore, the current QoE guarantee mechanism in the connected state is not applicable to terminals in the idle state and inactive state, and a new mechanism needs to be introduced to ensure QoE indicators.

[0214] Figure 1 A flow chart of a method for sending information provided in an embodiment of the present application, which method can be applied to a first network device, such as Figure 1 As shown, the method comprises the following steps:

[0215] Step 100: Generate prediction information, where the prediction information includes a result of QoE prediction and / or a result of RVQoE prediction for one or more terminals.

[0216] Step 101: Send prediction information to a second network device or one or more terminals; wherein the second network device is a network device where a cell where one or more terminals may reside is located.

[0217] Specifically, the first network device is a network device with a prediction function (for example, a base station). The first network device can perform QoE and / or RVQoE predictions on one or more terminals and generate prediction information. The prediction information may include the QoE prediction results and / or RVQoE prediction results of the one or more terminals. For example, the first network device can predict the services, trajectories, and QoE and / or RVQoE measurement indicators corresponding to the services or trajectories of one or more terminals, and the generated prediction information can be used to ensure the QoE and / or RVQoE of the one or more terminals. Ensuring the QoE and / or RVQoE of the terminal means taking certain measures to ensure that the QoE and / or RVQoE of the terminal service can meet the corresponding QoE indicator requirements and / or RVQoE indicator requirements.

[0218] In some embodiments, after generating the prediction information, the first network device can send the prediction information to the second network device. The second network device is the network device where the cell where the one or more terminals may reside is located. The first network device can predict the cell where the one or more terminals may reside in the future, and then determine the second network device. The second network device can be one or more, and the prediction information sent to different second network devices can be different.

[0219] When one of the one or more terminals resides (or accesses) in a cell under a second network device in the future, the second network device can guarantee the QoE and / or RVQoE of the resident (or accessed) terminal based on the prediction information. The second network device can provide QoE and / or RVQoE guarantees for terminals in an idle or inactive state, and can also provide QoE and / or RVQoE guarantees for terminals in a connected state.

[0220] For example, the second network device can provide QoE and / or RVQoE guarantees for the terminal that moves from an idle state to the second network device, such as ensuring the QoE and / or RVQoE of the terminal receiving MBS services in the idle state; the second network device can also provide QoE and / or RVQoE guarantees for the terminal that accesses the second network device and enters a connected state. For example, if the terminal moves from an idle state to the second network device and then accesses the second network device and enters a connected state, the second network device can also provide QoE and / or RVQoE guarantees for the terminal.

[0221] In some embodiments, the first network device may send the prediction information to the second network device using an interface message between base stations, such as an Xn interface message or other newly added interface messages between base stations.

[0222] After the second network device receives the prediction information sent by the first network device, it can guarantee the QoE and / or RVQoE of the relevant terminal in the future (for example, in an idle state or an inactive state, or after re-entering a connected state) according to the prediction information. For example, the second network device can determine the prediction index of QoE and / or RVQoE. If the prediction index of QoE and / or RVQoE corresponding to a certain MBS service does not meet the requirements, the second network device can optimize and guarantee the MBS service according to the arrival time of the corresponding terminal, the location of the terminal and other information, for example, it can use methods such as allocating more resources to ensure it.

[0223] In some embodiments, after generating the prediction information, the first network device may send the prediction information to each terminal, and each terminal may guarantee its own QoE and / or RVQoE based on the prediction information. For example, the first network device may generate prediction information for each terminal based on the result of predicting the QoE and / or RVQoE of each terminal, and send it to each terminal, so that each terminal can guarantee its own QoE and / or RVQoE based on its own prediction information. Among them, the guarantee of each QoE and / or RVQoE can be to guarantee the QoE and / or RVQoE of the terminal in an idle state or an inactive state, or to guarantee the QoE and / or RVQoE of the terminal in a connected state, and this application does not limit this.

[0224] In some embodiments, the first network device may send the prediction information to each terminal using any existing or newly added message sent to the terminal in the connected state, and this application does not specifically limit this.

[0225] After receiving the prediction information, the terminal can guarantee the QoE and / or RVQoE of the terminal in the future (such as in an idle state or an inactive state, or after re-entering a connected state) according to the content of the prediction information. For example, when performing cell reselection, the terminal can give priority to selecting a cell with better predicted QoE and / or RVQoE indicators for residence.

[0226] According to the information sending method provided in the embodiment of the present application, the first network device can send prediction information including the QoE and / or RVQoE prediction results of the terminal to the second network device or the terminal, so that the second network device or the terminal can ensure the QoE and / or RVQoE of the terminal based on the prediction information, which is conducive to ensuring and improving the user experience quality of the terminal performing MBS services.

[0262] Step 200: Receive prediction information sent by the first network device.

[0263] Step 201: Ensure QoE and / or RVQoE of one or more terminals based on prediction information.

[0264] Specifically, the first network device is a network device with a prediction function. The first network device can perform QoE and / or RVQoE predictions on one or more terminals and generate prediction information.

[0280] (3) The predicted probability of the terminal staying in the cell, which is used to indicate the accuracy of the prediction of the cell stay.

[0281] For example, assuming that the terminal associated with the first cell information is terminal 1 and the associated cell is cell 1, then this information refers to the predicted probability that terminal 1 resides in cell 1.

[0282] (4) Predicted service information of the terminal when it resides in the cell. The service information can be used to indicate which services the terminal may perform when it resides in the cell, and / or information about these services.

Ensuring the QoE and / or RVQoE of the terminal means taking certain measures to ensure that the QoE and / or RVQoE of the terminal service can meet the corresponding QoE indicator requirements and / or RVQoE indicator requirements.

[0292] In some embodiments, after generating the prediction information, the first network device may send the prediction information to each terminal, and each terminal may guarantee its own QoE and / or RVQoE based on the prediction information. For example, the first network device may generate corresponding prediction information for each terminal respectively, and send it to each terminal, so that each terminal can guarantee its own QoE and / or RVQoE based on its own prediction information. Among them, the guarantee of each QoE and / or RVQoE can be to guarantee the QoE and / or RVQoE of the terminal in an idle state or an inactive state, or to guarantee the QoE and / or RVQoE of the terminal in a connected state, and this application does not limit this.

[0293] In some embodiments, the first network device may send the prediction information to each terminal using any existing or newly added message sent to the terminal in the connected state, and this application does not specifically limit this.

[0294] After receiving the prediction information, the terminal can guarantee the QoE and / or RVQoE of the terminal in the future (such as in an idle state or an inactive state, or after re-entering a connected state) according to the content of the prediction information. For example, when performing cell reselection, the terminal can give priority to selecting a cell with better predicted QoE and / or RVQoE indicators for residence.

[0295] In the method for ensuring QoE provided in the embodiment of the present application, the first network device can send prediction information including the QoE and / or RVQoE prediction results of the terminal to the terminal, so that the terminal can ensure its own QoE and / or RVQoE based on the prediction information, which is conducive to ensuring and improving the user experience quality of the terminal performing MBS services.

[0296] In some embodiments, the prediction information includes at least one second cell information, and each second cell information is associated with a cell where the terminal may reside.

[0297] For example, assuming that the terminal is terminal 1, the first network device predicts that the cells where terminal 1 may reside in the future are cell 1, cell 2, cell 3, cell 4, and cell 5, then there are 5 second cell information, among which the first first cell information may be associated with cell 1 and include information related to cell 1, the second first cell information may be associated with cell 2 and include information related to cell 2, the third first cell information may be associated with cell 3 and include information related to cell 3, the fourth first cell information may be associated with cell 4 and include information related to cell 4, and the fifth first cell information may be associated with cell 5 and include information related to cell 5.

[0298] In some embodiments, the at least one second cell information may be in the form of cell list information, and the cell list information includes at least one second cell information.

[0299] In some embodiments, the second cell information includes one or more of the following:

[0312] The methods provided in the embodiments of the present application are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0313] The following describes the methods provided in the above embodiments of the present application by using examples of specific application scenarios.

[0314] Example 1: A QoE and / or RVQoE assurance solution is implemented on the network side.

[0315] In the related technology, after the base station prediction function completes the QoE and / or RVQoE prediction of the UE, when the UE switches, the prediction result of QoE and / or RVQoE will be sent to the base station where the switching target cell is located, and the base station where the switching target cell is located will continue to guarantee the QoE and / or RVQoE of the UE. However, for the UE receiving MBS services, the UE can continue to receive MBS services when it is released to an idle state or an inactive state by the base station. At this time, there is no context information of the UE on the base station, and the switching will not be triggered. Therefore, the prediction result of QoE and / or RVQoE will not be sent to the target base station during the switching. At this time, a new interaction mechanism between base stations needs to be introduced.

[0316] After the base station releases the UE to an idle state or an inactive state, the UE may trigger a cell reselection, and the UE selects a target cell to reside in, and the base station does not know the cell where the UE resides. In order to ensure the QoE and / or RVQoE of the UE in an idle state or an inactive state, the base station (i.e., the first network device) may send prediction information to one or more base stations (i.e., the second network device) where the cell where the UE may reside is located based on the trajectory prediction result, and notify the relevant base stations to perform QoE and / or RVQoE guarantees, and the relevant base stations perform QoE and / or RVQoE guarantees based on the prediction information.

[0317] The specific method is to send a message between base stations, the message content is UE list information, the list contains at least one node (that is, the UE list information contains at least one UE information), and each node contains at least one of the following:

[0318] (1)UE identification information.

[0319] (2) predicting a cell list information of the base station where the UE may reside in the future, where the list includes at least one node (that is, the cell list information includes at least one first cell information), and each node includes at least one of the following items:

[0320] a. Cell identification information.

[0321] b. The predicted UE residence time information in the cell may include at least one piece of information such as the predicted residence start time point, residence end time point, and residence time length.

[0322] c. The predicted probability of the UE residing in the cell, which is used to indicate the accuracy of the prediction of the cell residence.

[0323] d. Predicted service information of the UE when it resides in the cell.

[0324] e. The predicted QoE and / or RVQoE prediction indicators corresponding to the services performed by the UE when it resides in the cell.

[0325] f. Predicted UE location information, such as longitude and latitude information, distance from the base station, direction, angle and other information.

[0326] g. MBS service identifier corresponding to the prediction indicator of QoE and / or RVQoE.

[0327] The inter-base station message involves the Xn interface and can be sent using an existing message or a newly added message.

[0328] After receiving the above-mentioned inter-base station message, the relevant base station can guarantee the subsequent QoE and / or RVQoE of the UE (for example, in an idle state or an inactive state, or after re-entering a connected state) according to the content of the message. For example, the relevant base station can determine the prediction indicators of QoE and / or RVQoE. If the prediction indicators of QoE and / or RVQoE corresponding to a certain MBS service do not meet the requirements, the relevant base station can optimize and guarantee the MBS service according to information such as the arrival time of the UE and the location of the UE, for example, it can use methods such as allocating more resources to ensure it.

[0329] Example 2: A solution for ensuring QoE and / or RVQoE on the UE side.

[0330] The base station predicts the QoE and / or RVQoE of the UE. If the UE performs MBS services, the UE can receive the MBS services in an idle or inactive state. At this time, the UE is responsible for mobility control. The network does not have the UE context and cannot perform UE mobility control. However, the network side can provide auxiliary information to guide the UE to reselect a cell in an idle state based on the UE's QoE and / or RVQoE prediction results. The UE can try to select a cell with better QoE and / or RVQoE quality to reside in.

[0331] The specific method may be that the network side sends the following prediction information to the UE, which may include the predicted UE trajectory information, and the prediction information includes one or more cell information (i.e., second cell information), and each cell information includes at least one of the following:

[0332] a. Cell identification information.

[0333] b. The predicted UE residence time information in the cell may include at least one piece of information such as the residence start time point, the residence end time point, and the residence time length.

[0334] c. The predicted probability of the UE staying in the cell, that is, the accuracy of the prediction.

[0335] d. Predicted service information of the UE when it resides in the cell.

[0336] e. The predicted QoE and / or RVQoE prediction indicators corresponding to the services performed by the UE when it resides in the cell.

[0337] f. Predicted UE location information, such as longitude and latitude information, distance from the base station, direction, angle and other information.

[0338] g. Cell reselection priority information, used to guide the UE to perform cell reselection.

[0339] h. MBS service identifier corresponding to the prediction indicator of QoE and / or RVQoE.

[0340] After receiving the above prediction information, the UE can guarantee the QoE and / or RVQoE of the UE in the future (for example, in an idle state or an inactive state, or after re-entering a connected state) according to the content of the prediction information. For example, when performing cell reselection, the UE can give priority to selecting a cell with better predicted QoE and / or RVQoE indicators for residence.
