Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information processing method, apparatus and computer-readable storage medium. Background Technology

[0002] When the MBS (Multicast / Broadcast Service) service corresponding to an MBS session has no data transmission for a period of time, the core network can initiate an MBS session deactivation process. After the MBS session is deactivated, the MBS session enters an inactive state. The core network retains information related to this MBS session, while the access network releases all radio resources related to this MBS session and deletes information related to this MBS session.

[0003] For an inactive MBS session, when the user plane needs to transmit data again, the core network will instruct the access network to activate the MBS session and continue to transmit MBS data on this MBS session.

[0004] When the MBS session state changes as described above, the base station needs to notify the terminal of the event so that the terminal can take appropriate action. For terminals in an idle or inactive state, the base station needs to notify the terminal using a specific notification mechanism after the MBS session is reactivated, so that the terminal can restart MBS data reception through a specific procedure.

[0005] Paging technology has been around for a long time. Base stations use paging mechanisms to establish communication with terminals that are in an idle or inactive state. After receiving a paging message, a terminal can initiate an RRC (Radio Resource Control) connection establishment with the base station as needed. Terminals within the same cell are divided into different paging groups based on their terminal identifiers, and terminals in the same paging group listen for paging messages in the same time period.

[0006] In NR (New Radio) MBS, paging technology has been extended to MBS services. Terminals are notified of changes in the MBS session's status by including the session identifier (MBS session ID) in the paging message. Currently, paging messages used to notify of MBS session status changes occur during all regular paging occasions. Therefore, regardless of terminal type, all terminals receive and process the corresponding paging message, leading to unnecessary power consumption for terminals that do not support MBS services. Summary of the Invention

[0067] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0068] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0069] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0070] This application provides an information processing method, apparatus, and computer-readable storage medium to reduce power consumption of terminals that do not have the capability to support MBS services.

[0071] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0072] See Figure 1 , Figure 1 This is a flowchart of the information processing method provided in the embodiments of this application, such as... Figure 1 As shown, it includes the following steps:

[0073] Step 101: The network device determines the MBS session state change.

[0074] In this embodiment of the application, changes in the MBS session state can be determined by monitoring the MBS service corresponding to the MBS session. These changes include, but are not limited to, changes in the MBS session state to active, inactive, or released.

[0075] Step 102: The network device sends a DCI to the terminal, wherein the DCI carries indication information, which is used to indicate that the paging message carries information indicating changes in the MBS session state.

[0076] When a paging message is needed to notify of an MBS session state change, the network device sends a DCI to the terminal. When the state of an MBS session (such as a multicast session) changes, the network device can notify idle or inactive terminals of the MBS session state change via paging messages during all paging periods in the cell. In other words, in this situation, the network device needs to use a paging message to notify of the MBS session state change.

[0077] In this embodiment, the DCI is a P-RNTI scrambled DCI with a format of 1_0. The indication information is carried in the Short Messages Indicator and / or Short Messages of the DCI.

[0078] Specifically, if the content represented by the Short Messages Indicator and / or Short Messages meets preset conditions, then the indication information is determined to be used to indicate that the paging message carries information indicating changes in the MBS session state.

[0079] Meeting the preset conditions can include setting the field value to a preset numerical value or a preset character. The preset conditions for ShortMessages Indicator and Short Messages can be the same or different.

[0080] For example, in the embodiments of this application, the indication information can be carried in at least the following ways:

[0081] In the first method, the instruction message is carried via the Short Messages Indicator.

[0082] When the value of the Short Messages Indicator is a first preset value, it indicates that the paging message carries information indicating a change in the MBS session state. The first preset value is 00. In this embodiment, when the value of the Short Messages Indicator is 00, it indicates that the paging message carries information indicating a change in the MBS session state (e.g., a change in state to active, inactive, or released); otherwise, it indicates that the paging message does not carry information indicating a change in the MBS session state.

[0083] In the second method, the indication information is carried via Short Messages Indicator and Short Messages.

[0084] When the value of the Short Messages Indicator is a first preset value and the value of the MBS status change indication information field of the Short Messages is a second preset value, it indicates that the paging message carries information indicating a change in the MBS session status; otherwise, it indicates that the paging message does not carry information indicating a change in the MBS session status.

[0085] In this embodiment, an MBS status change indication information field is added to Short Messages, and the value of the MBS status change indication information field indicates whether the paging message carries information indicating a change in the MBS session status. The first preset value is 00, and the second preset value can be set as needed, such as to 1 or TRUE.

[0086] In this approach, for terminals capable of supporting MBS services, when the value of Short MessagesIndicator is 00, it is necessary to combine this value with the value of the MBS status change indication field in Short Messages to determine whether the paging message carries information indicating a change in MBS session status. When the value of Short MessagesIndicator is 00, if the value of the MBS status change indication field is 1 or TRUE, then the paging message carries information indicating a change in MBS session status; otherwise, the paging message does not carry information indicating a change in MBS session status.

[0087] In the third method, the instruction information is carried via Short Messages.

[0088] When the Short Messages include an MBS state change indication information field and the value of the MBS state change indication information field is a third preset value, it is used to indicate that the paging message carries information indicating a change in the MBS session state.

[0089] Specifically, in this embodiment, an MBS status change indication information field is added to Short Messages, and the value of the MBS status change indication information field indicates whether the paging message carries information indicating a change in the MBS session status. The third preset value can be set as needed, for example, to 1 or TRUE. If the value of the MBS status change indication information field is 1 or TRUE, then the paging message carries information indicating a change in the MBS session status; otherwise, the paging message does not carry information indicating a change in the MBS session status.

[0090] For example, when a paging procedure is triggered to notify of changes in the status of an MBS session (such as a multicast session), the network device (such as a base station) adds a 1-bit group paging indication to the Short Messages of the DCI scrambled with P-RNTI in format 1_0, indicating the change in the multicast session status. When the DCI schedules group paging, the "Short Messages Indicator" is set to 00 (Reserved), and the group paging indication in the Short Messages is set to 1.

[0091] In this embodiment, the network device carries indication information in the DCI to indicate that the paging message carries information indicating a change in the MBS session state. Using the solution of this embodiment, a terminal lacking MBS service support can refuse to receive the paging message when it determines, based on the indication information, that the paging message carries information indicating a change in the MBS session state. This avoids the terminal lacking MBS service support from receiving the paging message, reducing power consumption.

[0092] See Figure 2 , Figure 2 This is a flowchart of the information processing method provided in the embodiments of this application, such as... Figure 2 As shown, it includes the following steps:

[0093] Step 201: The terminal receives the DCI sent by the network device.

[0094] The DCI is a P-RNTI scrambled DCI with a format of 1_0.

[0095] Step 202: The terminal obtains indication information from the DCI, the indication information being used to indicate that the paging message carries information indicating a change in the MBS session state.

[0096] As previously mentioned, the indication information is carried in the Short Messages Indicator and / or Short Messages field of the DCI. Therefore, in this step, the terminal obtains the indication information from the Short Messages Indicator field and / or Short Messages field of the DCI.

[0097] Specifically, the terminal determines whether the content represented by the Short Messages Indicator field and / or the Short Messages field of the DCI meets preset conditions, and obtains a determination result. If the determination result is that the preset conditions are met, the terminal determines the indication information based on the represented content.

[0098] Step 203: The terminal determines whether to receive the paging message sent by the network device based on the indication information and whether it has the capability to support MBS services.

[0099] In this step, if the terminal has the capability to support MBS services, it determines to receive the paging message sent by the network device according to the indication information; if the terminal does not have the capability to support MBS services, it determines to refuse to receive the paging message sent by the network device according to the indication information.

[0100] Depending on the different indication methods of the network device, the terminal may have different ways to determine whether to receive the paging message.

[0101] In the first method, the indication information is carried via a Short Messages Indicator.

[0102] In this mode, when the terminal does not have the capability to support MBS services and the value of the Short MessagesIndicator is a first preset value, it is determined that the paging message will be rejected. When the terminal has the capability to support MBS services and the value of the Short MessagesIndicator is a first preset value, it is determined that the paging message will be received.

[0103] The first preset value is 00. Therefore, when the Short Messages Indicator value is 00, it indicates that the paging message carries information indicating a change in the MBS session state (e.g., a state change to active, inactive, or released). In this case, terminals that do not support MBS services can refuse to receive the paging message, while terminals that do support MBS services can accept the paging message.

[0104] In the second method, the indication information is carried via Short Messages Indicator and Short Messages.

[0105] When the terminal does not have the capability to support MBS services and when the value of the Short Messages Indicator is a first preset value, it is determined that the paging message will be refused.

[0106] In this method, the first preset value is 00. Since terminals that do not support MBS cannot recognize ShortMessages, this type of terminal can determine whether to receive paging messages based on the value of the Short Messages Indicator. When the value of the Short Messages Indicator is 00, it indicates that the paging message carries information indicating a change in the MBS session state (e.g., a change in state to active, inactive, or released), and in this case, it can be determined that the paging message should not be received; otherwise, it indicates that the paging message does not carry information indicating a change in the MBS session state, and the paging message can be received.

[0107] For a terminal capable of supporting MBS services, the paging message is determined to be received when the following conditions are met: the value of the Short Messages Indicator is a first preset value, and the value of the MBS status change indication information field of the Short Messages is a second preset value.

[0108] In this method, the first preset value is 00, and the second preset value can be set as needed, such as to 1 or TRUE. When the Short Messages Indicator value is 00, the value of the MBS status change indication information field in ShortMessages needs to be considered to determine whether the paging message carries information indicating a change in MBS session status. When the Short Messages Indicator value is 00, if the MBS status change indication information field value is 1 or TRUE, then the paging message carries information indicating a change in MBS session status, and a terminal capable of supporting MBS services will receive the paging message; otherwise, the paging message does not carry information indicating a change in MBS session status.

[0109] In the third method, the instruction information is carried via Short Messages.

[0110] Specifically, the indication information is carried through the MBS status change indication information field of Short Messages. When the Short Messages include the MBS status change indication information field and the value of the MBS status change indication information field is a third preset value, it indicates that the paging message carries information indicating a change in the MBS session status. The third preset value can be set as needed, for example, to 1 or TRUE.

[0111] For terminals that do not support MBS services, they cannot recognize the MBS status change indication information field of Short Messages. Therefore, when a terminal that does not support MBS services cannot recognize the MBS status change indication information field, it will refuse to receive the paging message; otherwise, it can receive the paging message.

[0112] When the Short Messages include an MBS status change indication information field and the value of the MBS status change indication information field is a third preset value, it indicates that the paging message carries information indicating a change in the MBS session status, and a terminal capable of supporting MBS services determines to receive the paging message.

[0113] In this embodiment, the network device carries indication information in the DCI to indicate that the paging message carries information indicating a change in the MBS session state. Using the solution of this embodiment, a terminal lacking MBS service support can refuse to receive the paging message when it determines, based on the indication information, that the paging message carries information indicating a change in the MBS session state. This avoids the terminal lacking MBS service support from receiving the paging message, reducing power consumption.

[0114] like Figure 3 As shown, the information processing method in this application embodiment includes:

[0115] Step 301: MBS Session Activation Process.

[0116] Specifically, the base station triggers the paging process and sets the corresponding fields in the DCI with P-RNTI scrambling format 1_0 as follows:

[0117] - Set "Short Messages Indicator" to 00 (Reserved).

[0118] - Set the MBS state change indication field in "Short Messages" (e.g., "MBS statechange indication") to 1.

[0119] For terminals that support MBS (MBS UE), the processing procedure includes steps 302-306; for terminals that do not have the capability to support MBS services, the processing procedure includes steps 307-308.

[0120] Step 302: The MBS UE listening to the paging channel receives the DCI scrambled by P-RNTI.

[0121] Step 303: The MBS UE determines whether it needs to receive a paging message based on the DCI information and receives the paging message.

[0122] Specifically, the MBS UE determines that the value of "Short Messages Indicator" in the DCI is 00, and decides that the "Short Messages" field needs to be further checked. Based on the MBS status change indication information field in "Short Messages", it determines that the paging message transmitted on the PDSCH (Physical downlink shared channel) contains information indicating the MBS session status change. Therefore, it decides to receive the paging message.

[0123] Step 304: The base station sends a paging message, which includes the activated MBS session identifier (i.e., MBSsession ID). Correspondingly, the MBS UE receives the paging message transmitted on the PDSCH channel.

[0124] Step 305: The MBS UE checks whether the paging message contains the MBS identifier of interest (such as MBS sessionID).

[0125] Step 306: If the paging message contains an MBS session that the MBS UE is interested in, the MBS UE triggers the corresponding procedure to continue receiving user plane data for that MBS session.

[0126] Step 307: Terminals that do not support MBS and are monitoring the paging channel receive P-RNTI scrambled DCI.

[0127] Step 308: Terminals that do not support MBS determine that the value of "Short Messages Indicator" in DCI is 00, interpret it as an invalid value, and then determine to refuse to receive paging messages on PDSCH, and the process ends.

[0128] In this embodiment, the network device carries indication information in the DCI to indicate that the paging message carries information indicating a change in the MBS session state. Using the solution of this embodiment, a terminal lacking MBS service support can refuse to receive the paging message when it determines, based on the indication information, that the paging message carries information indicating a change in the MBS session state. This avoids the terminal lacking MBS service support from receiving the paging message, reducing power consumption.
