[0058] 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 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.

[0059] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data 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", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0060] The following describes in detail the business processing method provided by the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0061] See also Figure 1 , Figure 1 1 is a flow chart of a service processing method provided by an embodiment of the present application, the method is applied to a terminal, and the terminal is in an inactive state. Figure 1 As shown, the method comprises the following steps:

[0062] Step 11: After the terminal reselects the target base station, it sends a request message to the target base station.

[0063] In this embodiment, the request message is used to request to receive MBS. For example, when a terminal receiving MBS reselects a cell after entering the inactive state, after reselecting a target cell, an active request to receive MBS can be initiated at a target base station corresponding to the target cell, that is, a request message for requesting to receive MBS is sent to the target base station.

[0064] Optionally, the request message may be sent via a Radio Resource Control (RRC) resume request message.

[0065] In the service processing method of the embodiment of the present application, after the terminal in the inactive state reselects the target base station, it can send a request message to the target base station, and the request message is used to request to receive the MBS. This can help the terminal to quickly resume the reception of the MBS, thereby ensuring the continuity of obtaining the MBS and improving the QoS performance of obtaining the MBS.

[0066] Optionally, the request message may include at least one of the following:

[0067] First indication information for indicating that the terminal expects to receive the MBS; for example, the first indication information may be 1-bit information, such as 0 or 1, wherein when it is 1, it may indicate that the terminal expects to receive the MBS, and when it is 0 or the terminal does not send the first indication information, it indicates that the terminal does not expect to receive the MBS;

[0068] second indication information of the MBS that the terminal is interested in;

[0069] The reason why the terminal enters the inactive state may include any one of the following: cell congestion, heavy cell load, not for power saving for the terminal, not ordinary entry into the inactive state, special entry into the inactive state.

[0070] It should be noted that in the embodiment of the present application, the MBS that the terminal is interested in may also be referred to as the MBS that the terminal expects to receive, the MBS that the terminal hopes to receive, etc., and there is no limitation on this.

[0071] The reason why the terminal enters the inactive state may specifically be the reason why the terminal enters the inactive state in the source cell. The cell congestion may be the source cell congestion. The cell heavy load may be the source cell heavy load. With the help of the reason why the terminal enters the inactive state, it can be known that the reason why the terminal enters the inactive state is not to save power for the terminal, so that if the target base station or the target cell is not congested or the load is not heavy, the terminal can be pulled back to the connected state to receive the MBS, thereby improving the performance of receiving the MBS. The source base station is the base station corresponding to the source cell.

[0072] Optionally, the second indication information may include but is not limited to at least one of the following items of the MBS of interest to the terminal: temporary mobile group identity (TMGI), multicast group identity, multicast address, multicast context identity, multicast quality of service (QoS) flow identity, etc.

[0073] Optionally, after sending the request message to the target base station, the terminal may receive time and / or frequency resource information of the MBS that the terminal is interested in from the target base station, and use the time and / or frequency resource information to receive the MBS.

[0074] In one implementation, the terminal may receive the time and / or frequency resource information of the MBS that the terminal is interested in through the system information broadcast by the target base station.

[0075] Optionally, after sending the request message to the target base station, the terminal may receive third indication information from the target base station; wherein the third indication information is used to instruct the terminal to enter the connected state to receive the MBS of interest. For example, if the target base station or target cell is not congested or not heavily loaded, and / or the QoS requirement of the MBS of interest to the terminal is high, the target base station or target cell may instruct the terminal to enter the connected state to receive the MBS of interest, thereby improving the performance of receiving the MBS.

[0076] In the embodiment of the present application, for a terminal in an inactive state to actively request the reception of an MBS at a target base station, it may be instructed by a source base station or agreed upon by a protocol. In the case of being instructed by a source base station, the terminal may receive fourth indication information from the source base station, and the fourth indication information is used to indicate: allowing or not allowing the terminal to actively request the reception of an MBS when in an inactive state.

[0077] For example, the fourth indication information may be carried in an RRC Release message sent by the source base station to a terminal such as a user equipment (UE), and is used to indicate whether the UE is allowed or not to actively request the reception of the MBS when entering the inactive state, such as actively requesting the reception of the MBS through the RRC resume request process after reselecting the target cell. Among them, for MBS with higher QoS requirements, the network side tends to allow, so that the UE does not need to wait for receiving system information before knowing whether the target base station is broadcasting the MBS, and through the active request, the target base station can restore the UE to the connected state to receive the MBS when the load is not heavy. Since the quality of the reception can be fed back in the connected state, retransmission, etc., better QoS guarantee for the MBS can be provided. For MBS with low QoS requirements, the network side tends to not allow, so that the UE can receive the MBS of interest according to the instructions in the broadcast message. If the reselected target base station does not broadcast the MBS of interest to the UE, the UE cannot receive the MBS.

[0078] Optionally, the terminal may receive a reason for the terminal entering the inactive state from the source base station; wherein the reason for the terminal entering the inactive state may include but is not limited to any of the following: cell congestion, heavy cell load, not for terminal power saving, not ordinary entry into the inactive state, special entry into the inactive state, etc. Thus, it can be learned that the reason for the terminal entering the inactive state is not for terminal power saving, so that if the target base station or target cell is not congested or not heavily loaded later, the terminal can be pulled back to the connected state to receive the MBS, thereby improving the performance of receiving the MBS.

[0079] In one implementation, the reason why the terminal enters the inactive state may be carried in an RRC release message sent by the source base station to the terminal.

[0080] Optionally, the process of sending the request message to the target base station may include any one of the following:

[0081] When the terminal receives fourth indication information from the source base station, and the fourth indication information indicates that the terminal is allowed to actively request reception of the MBS when in an inactive state, sending a request message to the target base station;

[0082] When the terminal determines, according to the protocol, that it is allowed to actively request the reception of the MBS when the terminal is in an inactive state, the terminal sends a request message to the target base station.

[0083] In this way, with the help of the instructions or protocol agreements of the source base station, the terminal can determine that it is allowed to actively request the reception of MBS when it is in an inactive state. Therefore, when the terminal reselects the target base station in an inactive state, it can send a request message to the target base station to request the reception of MBS, which can help the terminal quickly resume the reception of MBS, ensure the continuity of obtaining MBS, and improve the QoS performance of obtaining MBS.

[0084] See also Figure 2 , Figure 2 1 is a flow chart of a service processing method provided in an embodiment of the present application, and the method is applied to a base station, which is, for example, a target base station. Figure 2 As shown, the method comprises the following steps:

[0085] Step 21: Receive a request message from a terminal in an inactive state.

[0086] In this embodiment, the request message is used to request the reception of MBS. For example, a terminal receiving MBS reselects a cell after entering the inactive state. After reselecting a target cell, the terminal can initiate an active request to receive MBS at a target base station corresponding to the target cell, and the target base station receives the request message for requesting the reception of MBS.

[0087] Optionally, the above request message may be sent as an RRC recovery request message.

[0088] In the service processing method of the embodiment of the present application, the base station can receive a request message from an inactive terminal, the request message being used to request reception of an MBS, thereby helping the terminal to quickly resume reception of the MBS, thereby ensuring the continuity of obtaining the MBS and improving the QoS performance of obtaining the MBS.

[0089] Optionally, the request message may include at least one of the following:

[0090] First indication information for indicating that the terminal expects to receive the MBS; for example, the first indication information may be 1-bit information, such as 0 or 1, wherein when it is 1, it may indicate that the terminal expects to receive the MBS, and when it is 0 or the terminal does not send the first indication information, it indicates that the terminal does not expect to receive the MBS;

[0091] second indication information of the MBS that the terminal is interested in;

[0092] The reason why the terminal enters the inactive state may include any one of the following: cell congestion, heavy cell load, not for power saving for the terminal, not ordinary entry into the inactive state, special entry into the inactive state.

[0093] It should be noted that in the embodiment of the present application, the MBS that the terminal is interested in may also be referred to as the MBS that the terminal expects to receive, the MBS that the terminal hopes to receive, etc., and there is no limitation on this.

[0094] The reason why the terminal enters the inactive state may specifically be the reason why the terminal enters the inactive state in the source cell. The cell congestion may be the source cell congestion. The cell heavy load may be the source cell heavy load. With the help of the reason why the terminal enters the inactive state, it can be known that the reason why the terminal enters the inactive state is not to save power for the terminal, so that if the target base station or the target cell is not congested or the load is not heavy, the terminal can be pulled back to the connected state to receive the MBS, thereby improving the performance of receiving the MBS.

[0095] Optionally, the second indication information may include but is not limited to at least one of the following items of the MBS that the terminal is interested in: TMGI, multicast group identifier, multicast address, multicast context identifier, multicast QoS flow identifier, etc.

[0096] Optionally, if the above-mentioned base station is a target base station, the service processing method in this embodiment may also include: sending a request message to a source base station, wherein the request message is used to request the MBS information of interest to the terminal, and receiving indication information of the MBS of interest to the terminal from the source base station, so that the target base station can know the MBS of interest to the terminal, thereby sending the time and / or frequency resource information of the MBS of interest to the terminal.

[0097] For example, after receiving a request message from an inactive terminal, the target base station may send request information for requesting MBS information of interest to the terminal to the source base station, and receive indication information of the MBS of interest to the terminal from the source base station, so as to learn the MBS of interest to the terminal.

[0098] Optionally, after receiving the request message from the terminal in the inactive state, the base station in this embodiment may further perform a first operation. The first operation may include at least one of the following:

[0099] When the base station is sending the MBS that the terminal is interested in, the base station sends the time and / or frequency resource information of the MBS that the terminal is interested in to the terminal, so that the terminal uses the time and / or frequency resource information to receive the MBS;

[0100] When the base station does not send the MBS that the terminal is interested in, it initiates a channel, service or session establishment request to the core network device, and after the channel, service or session of the MBS that the terminal is interested in with the core network is established, it sends the time and / or frequency resource information of the MBS that the terminal is interested in to the terminal; for example, the core network device may be a user plane function (UPF), a session management function (SMF), an access and mobility management function (AMF), etc.;

[0101] Sending third indication information to the terminal; wherein the third indication information is used to instruct the terminal to enter a connected state to receive the MBS of interest. For example, if the base station or cell is not congested or not heavily loaded, and / or the QoS requirement of the MBS of interest to the terminal is high, the base station may instruct the terminal to enter a connected state to receive the MBS of interest, thereby improving the performance of receiving the MBS.

[0102] As an optional embodiment, if the above-mentioned base station is a target base station, and the request message sent by the terminal includes second indication information, that is, the request message carries the indication information of the MBS that the terminal is interested in, then the target base station can directly perform the first operation after receiving the request message.

[0103] As another optional embodiment, if the above-mentioned base station is a target base station, the request message sent by the terminal includes the first indication information but does not include the second indication information. For example, the request message only includes the first indication information. Then before performing the first operation, the target base station also needs to perform the following steps: send a request information to the source base station, where the request information is used to request the MBS information of interest to the terminal; receive the indication information of the MBS of interest to the terminal from the source base station, so as to perform the first operation after knowing the MBS of interest to the terminal.

[0104] Optionally, the indication information of the MBS that the terminal is interested in may include but is not limited to TMGI, multicast group identifier, multicast address, multicast context identifier, multicast QoS flow identifier, etc. When the source base station provides the indication information of the MBS that the terminal is interested in to the target base station, it may not carry certain context information of the terminal, such as information related to the terminal itself, such as a key.

[0105] Optionally, if the above base station is a target base station, the target base station may receive the reason why the terminal enters the inactive state from the source base station; wherein the reason why the terminal enters the inactive state may include but is not limited to any of the following: cell congestion, heavy cell load, not for power saving for the terminal, not ordinary entry into the inactive state, special entry into the inactive state, etc. Thus, it can be known that the reason why the terminal enters the inactive state is not for power saving for the terminal, so that if the target base station or target cell is not congested or not heavily loaded later, the terminal can be pulled back to the connected state to receive the MBS, thereby improving the performance of receiving the MBS.

[0106] In one implementation, the source base station may proactively send the reason why the terminal enters the inactive state to the target base station, or may send the reason why the terminal enters the inactive state to the target base station based on a request from the target base station.

[0107] See also Figure 3 , Figure 3 1 is a flow chart of an information indication method provided by an embodiment of the present application, the method is applied to a terminal, the terminal is in an inactive state, for example. Figure 3 As shown, the method comprises the following steps:

[0108] Step 31: Receive fourth indication information from a base station.

[0109] In this embodiment, the fourth indication information is used to indicate: allowing or not allowing the terminal to actively request the reception of the MBS when in an inactive state.

[0110] For example, the terminal may receive fourth indication information from the source base station. The fourth indication information may be carried by the RRC release message sent by the source base station to the UE, and is used to indicate whether the UE is allowed or not to actively request the reception of the MBS when entering the inactive state, such as actively requesting the reception of the MBS through the RRCresume request process after reselecting the target base station. Among them, for MBS with higher QoS requirements, the network side tends to allow, so that the UE does not need to wait for the reception of system information before knowing whether the target base station is broadcasting the MBS, and through the active request method, the target base station or the target cell can restore the UE to the connected state to receive the MBS when the load is not heavy. Since the quality of the reception can be fed back in the connected state, retransmission, etc., better QoS guarantee for the MBS can be provided. For MBS with low QoS requirements, the network side tends to not allow, so that the UE can receive the MBS of interest according to the instructions in the broadcast message. If the reselected target base station does not broadcast the MBS of interest to the UE, the UE cannot receive the MBS.

[0111] The information indication method of the embodiment of the present application, by receiving the fourth indication information from the base station, can enable the terminal to actively request the reception of the MBS when it is in an inactive state, so that after the terminal reselects the target base station in an inactive state, it sends a request message to the target base station for requesting the reception of the MBS, thereby helping the terminal to quickly resume the reception of the MBS, ensure the continuity of obtaining the MBS, and improve the QoS performance of obtaining the MBS.

[0112] See also Figure 4 , Figure 4 1 is a flow chart of an information indication method provided in an embodiment of the present application, and the method is applied to a base station, such as a source base station. Figure 4 As shown, the method comprises the following steps:

[0113] Step 41: Send fourth indication information to the terminal.

[0114] In this embodiment, the fourth indication information is used to indicate: allowing or not allowing the terminal to actively request the reception of the MBS when in an inactive state.

[0115] For example, the fourth indication information can be carried by the RRC release message sent by the source base station to the UE, and is used to indicate whether the UE is allowed or not to actively request the reception of the MBS when entering the inactive state, such as actively requesting the reception of the MBS through the RRCresume request process after reselecting the target base station. Among them, for MBS with higher QoS requirements, the network side tends to allow it, so that the UE does not need to wait for the reception of system information before knowing whether the target base station is broadcasting the MBS, and through the active request method, the target base station or cell can restore the UE to the connected state to receive the MBS when the load is not heavy. Since the quality of the reception can be fed back in the connected state, retransmission, etc., better QoS guarantee for the MBS can be provided. For MBS with low QoS requirements, the network side tends to not allow it, so that the UE can receive the MBS of interest according to the instructions in the broadcast message. If the reselected target base station does not broadcast the MBS of interest to the UE, the UE cannot receive the MBS.

[0116] The information indication method of the embodiment of the present application, by sending the fourth indication information to the terminal, can enable the terminal to actively request the reception of the MBS when it is in an inactive state, so that after the terminal reselects the target base station in the inactive state, it sends a request message to the target base station for requesting the reception of the MBS, thereby helping the terminal to quickly resume the reception of the MBS, ensure the continuity of obtaining the MBS, and improve the QoS performance of obtaining the MBS.

[0117] See also Figure 5 , Figure 51 is a flow chart of an information indication method provided in an embodiment of the present application, the method is applied to a terminal or a target base station, the terminal is in an inactive state, for example. Figure 5 As shown, the method comprises the following steps:

[0118] Step 51: Receive the reason why the terminal enters the inactive state from the source base station.

[0119] In this embodiment, the reason why the terminal enters the inactive state may include but is not limited to any of the following: cell congestion, heavy cell load, not for power saving of the terminal, not ordinary entry into the inactive state, special entry into the inactive state, etc. For example, the reason why the terminal enters the inactive state may specifically be the reason why the terminal enters the inactive state in the source cell, and accordingly, the cell congestion is the source cell congestion, and the cell heavy load is the source cell heavy load.

[0120] In one implementation, the source base station may proactively send the reason why the terminal enters the inactive state to the target base station, or may send the reason why the terminal enters the inactive state to the target base station based on a request from the target base station.

[0121] In one implementation, the terminal may receive the reason why the terminal enters the inactive state from the source base station through an RRC release message.

[0122] Therefore, it can be known that the reason why the terminal enters the inactive state is not to save power for the terminal. Therefore, if the target base station or target cell is not congested or the load is not heavy, the terminal can be pulled back to the connected state to receive MBS, thereby improving the performance of receiving MBS.

[0123] See also Figure 6 , Figure 6 is a flow chart of an information indication method provided in an embodiment of the present application, and the method is applied to a source base station. Figure 6 As shown, the method comprises the following steps:

[0124] Step 61: Send the reason why the terminal enters the inactive state to the terminal and / or the target base station.

[0125] In this embodiment, the reason why the terminal enters the inactive state may include but is not limited to any of the following: cell congestion, heavy cell load, not for power saving of the terminal, not ordinary entry into the inactive state, special entry into the inactive state, etc. For example, the reason why the terminal enters the inactive state may specifically be the reason why the terminal enters the inactive state in the source cell, and accordingly, the cell congestion is the source cell congestion, and the cell heavy load is the source cell heavy load.

[0126] In one implementation, the source base station may proactively send the reason why the terminal enters the inactive state to the target base station, or may send the reason why the terminal enters the inactive state to the target base station based on a request from the target base station.

[0127] In one implementation manner, the source base station may send the reason why the terminal enters the inactive state to the terminal through an RRC release message.

[0128] Therefore, it can be known that the reason why the terminal enters the inactive state is not to save power for the terminal.

[0167] It is understandable that the service processing device 80 of the embodiment of the present application can implement the above Figure 2The various processes in the method embodiment shown can achieve the same technical effect, and will not be described again here to avoid repetition.

[0168] See also Fig. 9 , Fig. 9 is a schematic diagram of the structure of an information indication device provided in an embodiment of the present application, the device is applied to a terminal, and the terminal is in an inactive state, for example. Fig. 9 As shown, the information indicating device 90 includes:

[0169] A third receiving module 91, configured to receive fourth indication information from a base station;

[0170] The fourth indication information is used to indicate whether to allow or not to allow the terminal to actively request the reception of the MBS when in an inactive state.

[0171] For example, the terminal may receive fourth indication information from the source base station. The fourth indication information may be carried by an RRC release message sent by the source base station to the UE, and is used to indicate whether the UE is allowed or not to actively request the reception of the MBS when entering the inactive state, such as actively requesting the reception of the MBS through the RRCresume request process after reselecting the target base station.

[0172] Therefore, when the fourth indication information indicates that the terminal is allowed to actively request the reception of MBS when in an inactive state, the terminal can send a request message for requesting the reception of MBS to the target base station after reselecting the target base station in an inactive state, thereby helping the terminal to quickly resume the reception of MBS, ensure the continuity of obtaining MBS, and improve the QoS performance of obtaining MBS.

[0173] See also Fig.10 , Fig.10 is a schematic diagram of the structure of an information indication device provided in an embodiment of the present application, and the device is applied to a base station, such as a source base station. Fig.10 As shown, the information indicating device 100 includes:

[0174] The third sending module 101 is configured to send fourth indication information to the terminal.

[0175] The fourth indication information is used to indicate whether to allow or not to allow the terminal to actively request the reception of the MBS when in an inactive state.

[0176] For example, the fourth indication information can be carried by the RRC release message sent by the source base station to the UE, used to indicate whether the UE is allowed or not to actively request the reception of the MBS when entering the inactive state, such as actively requesting the reception of the MBS through the RRCresume request process after reselecting the target base station.

[0177] Therefore, when the fourth indication information indicates that the terminal is allowed to actively request the reception of MBS when in an inactive state, the terminal can send a request message for requesting the reception of MBS to the target base station after reselecting the target base station in an inactive state, thereby helping the terminal to quickly resume the reception of MBS, ensure the continuity of obtaining MBS, and improve the QoS performance of obtaining MBS.

[0178] See also Fig.11 , Fig.11 is a structural diagram of an information indication device provided in an embodiment of the present application, the device is applied to a terminal or a target base station, and the terminal is in an inactive state, for example. Fig.11 As shown, the information indicating device 110 includes:

[0179] The fourth receiving module 111 is configured to receive a reason why the terminal enters the inactive state from a source base station.

[0180] The reason why the terminal enters the inactive state may include any of the following: cell congestion, heavy cell load, not for power saving of the terminal, not ordinary entry into the inactive state, special entry into the inactive state. For example, the reason why the terminal enters the inactive state may specifically be the reason why the terminal enters the inactive state in the source cell. Correspondingly, the cell congestion is the source cell congestion, and the cell heavy load is the source cell heavy load.

[0181] Therefore, it can be known that the reason why the terminal enters the inactive state is not to save power for the terminal. Therefore, if the target base station or target cell is not congested or the load is not heavy, the terminal can be pulled back to the connected state to receive MBS, thereby improving the performance of receiving MBS.

[0182] See also Fig.12 , Fig.12 is a schematic diagram of the structure of an information indication device provided in an embodiment of the present application, and the device is applied to a source base station. Fig.12 As shown, the information indicating device 120 includes:

[0183] The fourth sending module 121 is configured to send the reason why the terminal enters the inactive state to the terminal and / or the target base station.

[0184] The reason why the terminal enters the inactive state includes any one of the following: cell congestion, heavy cell load, not for power saving of the terminal, not ordinary entry into the inactive state, special entry into the inactive state. For example, the reason why the terminal enters the inactive state may specifically be the reason why the terminal enters the inactive state in the source cell, and accordingly, the cell congestion is the source cell congestion, and the cell heavy load is the source cell heavy load.

[0185] Therefore, it can be known that the reason why the terminal enters the inactive state is not to save power for the terminal. Therefore, if the target base station or target cell is not congested or the load is not heavy, the terminal can be pulled back to the connected state to receive MBS, thereby improving the performance of receiving MBS.
