Description

[Technical Field]

[0001] This application claims priority from a Chinese patent application filed with the China Patent Office on March 30, 2022, bearing application number 202210330976.X, the entire contents of which are incorporated herein by reference.

[0002] Technical Field The present application relates to the field of communication technology, for example, to a processing method, a transmitting device, and a receiving device for a Multicast / Broadcast Service (MBS). [Background technology]

[0003] Background technology With the rapid development of 5th Generation Mobile Communication Technology (5G), the 3rd Generation Partnership Project (3GPP (registered trademark)) R13 newly introduces the RRC RRC_INACTIVE state in addition to the RRC_IDLE and RRC_CONNECTED states of Long Term Evolution (LTE), taking into account signaling overhead and power consumption. When a user is in the RRC_INACTIVE state, not only can power consumption be reduced, but the user can also quickly access the network, meeting the high-speed data rate requirements of 5G for the interconnection of all things, reducing signaling overhead, and avoiding the problem of excessive signaling overhead caused by a large number of devices transmitting small amounts of data sporadically. The 5G R15 specification inherits the RRC_INACTIVE state newly introduced in R13, and in actual operation, after a user equipment (UE) establishes a Radio Resource Control (RRC) connection, it is in the RRC_CONNECTED state, and can switch to the RRC_INACTIVE state, switch directly to the RRC_IDLE state, or switch to the RRC_INACTIVE state and then to the RRC_IDLE state according to the actual operating situation. Also, when the UE is in the RRC_IDLE state or the RRC_INACTIVE state, it may switch to the RRC_CONNECTED state according to the actual operating situation.

[0004] In the related technology, when a UE receives an RRC Release signaling and the RRC Release signaling includes a SuspendConfig message, the UE transitions from an RRC_CONNECTED state to an RRC_INACTIVE state and suspends all SRBs (Signaling Radio Bearers) and DRBs (Data Radio Bearers) except for SRB0.

[0019] Preferred Embodiments of the Invention The related art does not concern operational rules for MBS, such as whether or not the radio bearer of the MBS needs to be suspended, the time for which the radio bearer of the MBS is suspended, and how to suspend the radio bearer of the MBS.

[0020] The present application will be described below in conjunction with drawings and specific examples, but the present application is not limited thereto.

[0021] The present application solves the problems in the related art by providing an MBS processing method, a receiving device, and a transmitting device, and by introducing suspend information that indicates whether a receiving device (i.e., a UE) receiving an MBS suspends or not suspends a corresponding radio bearer, the continuity and scheduling flexibility of the MBS can be improved, network resources can be optimized, and UE power consumption can be reduced, thereby improving system performance and user experience. The suspend information of the present application may be newly generated by a base station or may be agreed upon by a protocol.

[0022] First, a processing method for MBS is provided, as shown in FIG. 1, the method includes:

[0023] S110: generate suspend information and send the suspend information, where the suspend information is used to instruct to suspend all radio bearers corresponding to the MBS, or to instruct not to suspend all radio bearers corresponding to the MBS, or to suspend some radio bearers among all radio bearers corresponding to the MBS and not to suspend the remaining radio bearers among all the radio bearers.

[0024] Each radio bearer corresponding to an MBS is a multicast broadcast radio bearer (MBS Radio Bearer, MRB).

[0025] 1 is performed by a base station. Illustratively, the base station sends suspend information to a UE, instructing the UE to perform one of the following: suspending all radio bearers corresponding to an MBS; not suspending all radio bearers corresponding to an MBS; or suspending some radio bearers among all radio bearers corresponding to an MBS and not suspending the remaining radio bearers among all radio bearers corresponding to an MBS.

[0026] For example, the base station transmits suspend information to the UE that has received the MBS. This application provides a method for processing an MBS, which generates suspend information to instruct a receiving device (i.e., a UE) receiving the MBS to suspend a radio bearer corresponding to the MBS upon receiving the suspend information, thereby improving the continuity and scheduling flexibility of the MBS, optimizing network resources, and reducing UE power consumption, thereby improving system performance and improving user experience. Each radio bearer corresponding to the MBS is an MRB.

[0027] In one embodiment of the present application, all MRBs of a receiving device that receives an MBS may be all MRBs that the receiving device currently has established.

[0028] In another embodiment of the present application, all MRBs of a receiving device that receives an MBS may be all MRBs that the receiving device currently has active.

[0029] In one embodiment of the present application, the total number of bits of the suspend information is 1 bit, and the 1 bit is assigned as 0 or 1.

[0030] The first allocation method is such that when the 1 bit is assigned a 0, the suspend information instructs that all MRBs of the receiving device receiving the MBS be suspended, and when the 1 bit is assigned a 1, the suspend information instructs that all MRBs of the receiving device receiving the MBS not be suspended; or the second allocation method is such that when the 1 bit is assigned a 0, the suspend information instructs that all MRBs of the receiving device receiving the MBS not be suspended, and when the 1 bit is assigned a 1, the suspend information instructs that all MRBs of the receiving device receiving the MBS are suspended.

[0031] Provided is a first method for generating suspend information in which the total number of bits of the suspend information is 1 bit, and the 1 bit is assigned with 0 or 1. When the 1 bit is assigned with 0 or 1, the suspend information instructs whether to suspend or not suspend all MRBs of a receiving device that receives an MBS. All MRBs of a receiving device that receives an MBS may be all MRBs currently established by the receiving device, or may be all MRBs currently activated by the receiving device. Therefore, in the first allocation method, a 0 is assigned to one bit of the suspend information to indicate that the receiving device receiving the MBS has suspended all currently established MRBs or all currently activated MRBs, and a 1 is assigned to one bit of the suspend information to indicate that the receiving device receiving the MBS will not suspend all currently established MRBs or all currently activated MRBs; in the second allocation method, a 0 is assigned to one bit of the suspend information to indicate that the receiving device receiving the MBS will not suspend all currently established MRBs or all currently activated MRBs, and a 1 is assigned to one bit of the suspend information to indicate that the receiving device receiving the MBS has suspended all currently established MRBs or all currently activated MRBs.

[0032] For example, if a receiving device receiving an MBS currently has 10 MRBs established, 5 MRBs currently activated, and 5 MRBs not currently activated, and the current operation is requesting that all activated MRBs be suspended, but if the suspend information indicates that the receiving device receiving an MBS should suspend or not suspend all currently established MRBs, the suspend information is generated using the first allocation method described above, and the generated suspend information is "0." The second allocation method is adopted, and the generated suspend information is " "1", and further, the receiving device receiving the MBS suspends all currently established MRBs so as to realize the current suspend request; on the other hand, if the suspend information indicates that the receiving device receiving the MBS suspends or does not suspend all currently activated MRBs, then the above-mentioned first allocation method is adopted and the generated suspend information is "0", and the above-mentioned second allocation method is adopted and the generated suspend information is "1", so as to indicate that the receiving device receiving the MBS suspends all currently activated MRBs.

[0033] In another embodiment of the present application, the total number of bits of the suspend information is the number of all MRBs of the receiving device that receives the MBS, and each bit is assigned with 0 or 1. The bits in the suspend information, which are ordered from the most significant bit to the least significant bit or from the least significant bit to the most significant bit, correspond one-to-one to all MRBs, which are ordered in ascending or descending order of the MRB identifier (ID). For each bit of the suspend information, a first allocation scheme is such that when 0 is assigned to the bit, the suspend information indicates that the MRB corresponding to the bit is suspended, and when 1 is assigned to the bit, the suspend information indicates that the MRB corresponding to the bit is not suspended; or a second allocation scheme is such that when 0 is assigned to the bit, the suspend information indicates that the MRB corresponding to the bit is not suspended, and when 1 is assigned to the bit, the suspend information indicates that the MRB corresponding to the bit is suspended.

[0034] A second method for generating suspend information is provided, in which the total number of bits of the suspend information generated by this method is the number of all MRBs of the receiving device that receives the MBS, and all bits based on the order from high-order bit to low-order bit or from low-order bit to high-order bit correspond one-to-one to all MRBs based on the ascending or descending order of MRB ID, that is, each bit corresponds to one MRB in order, and each bit is assigned with 0 or 1 to indicate whether the MRB corresponding to the bit is to be suspended or not suspended.

[0035] In the first allocation method, a value is assigned to each bit of the suspend information, and when a bit is assigned a 0, the suspend information indicates that the MRB corresponding to that bit is suspended, and when a bit is assigned a 1, the suspend information indicates that the MRB corresponding to that bit is not suspended.In the second allocation method, a value is assigned to each bit of the suspend information, and when a bit is assigned a 0, the suspend information indicates that the MRB corresponding to that bit is not suspend, and when a bit is assigned a 1, the suspend information indicates that the MRB corresponding to that bit is suspend.

[0036] All MRBs of a receiving device receiving an MBS may be all MRBs currently established by the receiving device, or may be all MRBs currently activated by the receiving device. That is, if the total number of bits of the suspend information is the number of all MRBs currently established by a receiving device receiving an MBS, all bits based on the order from most significant bit to least significant bit or from least significant bit to most significant bit correspond one-to-one to all MRBs currently established by a receiving device receiving an MBS based on the ascending or descending order of MRB IDs. When each bit in the suspend information is assigned 0 or 1, the suspend information indicates whether or not to suspend the MRB corresponding to that bit among all MRBs currently established by a receiving device receiving an MBS. If the total number of bits in the suspend information is the number of all MRBs currently activated by the receiving device receiving the MBS, all bits based on the order from most significant bit to least significant bit or from least significant bit to most significant bit correspond one-to-one to all MRBs currently activated by the receiving device receiving the MBS based on the ascending or descending order of MRB ID, and when each bit in the suspend information is assigned 0 or 1, the suspend information indicates whether or not to suspend the MRB corresponding to that bit among all MRBs currently activated by the receiving device receiving the MBS.

[0037] For example, if a receiving device receiving an MBS currently has 10 established MRBs, with MRB IDs being MRB1, MRB2, MRB3, ..., MRB10, and currently has 5 activated MRBs with MRB IDs being MRB1, MRB2, MRB3, MRB4, MRB5, and currently has 5 inactive MRBs with MRB IDs being MRB6, MRB7, MRB8, MRB9, MRB10, and the current operation request is to suspend MRB1 and MRB2, the total number of bits of the generated suspend information is the number of all MRBs currently established by the receiving device receiving the MBS, and if the above-mentioned first allocation method is adopted, the generated suspend information will be "0011111111" (the bits correspond to the MRB IDs in ascending order from high to low) or "1111111100" (the bits correspond to the MRB IDs in descending order from high to low). If the total number of bits of the suspend information is all MRBs currently established by the receiving device receiving the MBS and the second allocation method described above is adopted, the suspend information is "1100000000" (the bits correspond to the MRB IDs in ascending order from top to bottom) or "0000000011" (the bits correspond to the MRB IDs in descending order from top to bottom). If the total number of bits of the suspend information is the number of all MRBs currently activated by the receiving device receiving the MBS and the first allocation method described above is adopted, the suspend information is "00111" (the bits correspond to the MRB IDs in ascending order from top to bottom) or "11100" (the bits correspond to the MRB IDs in descending order from top to bottom). If the total number of bits of the suspend information is the number of all MRBs currently activated by the receiving device receiving the MBS and the second allocation method described above is adopted, the suspend information is "11000" (the bits correspond to the MRB IDs in ascending order from top to bottom) or "00011" (the bits correspond to the MRB IDs in descending order from top to bottom).

[0038] In another embodiment of the present application, the suspend information includes one or more MRB IDs, and the suspend information instructs suspending the MRBs corresponding to each of the one or more MRB IDs.

[0039] A third method for generating suspend information is provided. The suspend information generated by this method includes one or more MRB IDs, and suspends the MRBs corresponding to each MRB ID included in the suspend information. That is, the total number of bits in the suspend information is not fixed but depends on actual needs. The MRBs corresponding to the MRB IDs included in the suspend information are the MRBs for which the suspend information requests a suspend instruction. For example, a receiving device currently receiving an MBS has established 16 MRBs, with MRB IDs in ascending order as MRB1, MRB2, ..., MRB16. Each MRB ID occupies 4 bits and is represented in hexadecimal. If MRB1 and MRB3 are requested to be suspended, the suspend information may include "0001" and "0011," or the suspend information may be represented as "00010011" to indicate the suspension of MRB1 and MRB3. To avoid confusion between the suspend information and other information, the suspend information may include the number of MRB IDs included. For example, in the above example, if two MRBs need to be suspended, a "0010" field may be added before "0001" and "0011" to indicate that the suspend information is used to indicate that the MRBs corresponding to the two MRB IDs are to be suspended, and the suspend information may be expressed as "001000010011". Also, a bit may be added before or after the bit corresponding to each MRB ID to indicate whether there is an MRB ID before or after it. For example, a "1" may be used to indicate that there is another MRB ID after the MRB ID, and a "0" may be used to indicate that there is no other MRB ID after the MRB ID, and the suspend information may be expressed as "0001100110".

[0040] In one embodiment of the present application, the suspend information may be included in an RRC release (RRCRelease) message.

[0041] For example, the base station includes the generated suspend information in an RRCRelease message and sends the RRCRelease message, causing a receiving device receiving the MBS to receive the RRCRelease message, obtain the suspend information, and suspend the corresponding MRB.

[0042] Preferably, the suspend information is generated using any one of the three generation methods described above, and the suspend information can be included in the RRCRelease message and transmitted.

[0043] For example, the first allocation method of the first generation method is adopted to generate the suspend information, and the suspend information is used to instruct a receiving device receiving an MBS to suspend all currently activated MRBs. In a current communication system, if a UE receiving an MBS currently has five activated MRBs and the current operation requires that all activated MRBs of the receiving device receiving an MBS be suspended, the generated suspend information is "0". The format of the currently suspending RRCRelease message that needs to be sent is as follows:

[0044]

number

[0045] In addition to the part representing suspend information, the RRCRelease message has messages for other functions, and the ellipsis "..." is used to represent other parts of the message format, but the functions of "..." in the message formats below are the same.

[0046] For example, the suspend information is generated using the first allocation method of the second generation method, and the suspend information is used to instruct a receiving device receiving an MBS to suspend all currently activated MRBs. The bits from highest to lowest in the suspend information correspond to the MRB IDs in ascending order. In a current communication system, if a receiving device receiving an MBS currently has five MRBs activated and the current operation requires suspending MRB1 and MRB2 of the five MRBs, the suspend information generated is "00111". The format of the RRCRelease message that needs to be sent to suspend the current suspend is as follows:

[0047]

number

[0048] For example, the third generation method is used to generate suspend information, and the suspend information is used to instruct the MRB corresponding to the MRB ID to be suspended. In a current communication system, if a receiving device receiving an MBS currently has 10 MRBs established and the current operation requires MRB1 and MRB3 to be suspended, the generated suspend information is "00010011". The format of the RRCRelease message that needs to be sent to currently suspend is as follows:

[0049]

number

[0050] In one embodiment of the present application, the suspend information may be included in a SuspendConfig message. For example, the generated suspend information is included in a SuspendConfig message, and the SuspendConfig message is sent in an RRCRelease message, so that a receiving device that receives an MBS receives the SuspendConfig message, obtains the suspend information, and suspends the corresponding MRB.

[0051] It is also possible to generate suspend information using any one of the three generation methods described above and include the suspend information in the RRCRelease message.

[0052] For example, the first allocation method of the first generation method is adopted to generate the suspend information, and the suspend information is used to instruct a receiving device receiving an MBS to suspend all currently activated MRBs. In a current communication system, if a receiving device receiving an MBS currently activates five MRBs and the current operation requires that all activated MRBs be suspended, the generated suspend information is "0". The format of the currently suspended RRCRelease message that needs to be sent is as follows:

[0053]

number

[0054] The present application does not limit other parameters in the above-mentioned SuspendConfig, but only adds suspend information to the SuspendConfig parameter structure in the related art.

[0055] For example, the suspend information is generated using the first allocation method of the second generation method, and the suspend information is used to instruct a receiving device receiving an MBS to suspend all currently activated MRBs. The bits from highest to lowest in the suspend information correspond to the MRB IDs in ascending order. In a current communication system, if a receiving device receiving an MBS currently has five MRBs activated and the current operation requires suspending MRB1 and MRB2 of the five MRBs, the suspend information generated is "00111". The format of the RRCRelease message that needs to be sent to suspend the current suspend is as follows:

[0056]

number

[0057] For example, the third generation method is used to generate suspend information, and the suspend information is used to instruct the MRB corresponding to the MRB ID to be suspended. In a current communication system, if a receiving device receiving a current MBS currently has 10 MRBs established and the current operation requires suspending MRB1 and MRB3, the generated suspend information is "00010011". The format of the suspend RRCRelease message that currently needs to be sent is as follows:

[0058]

number

[0059] In one embodiment of the present application, the suspend information may be further borne by control signaling, which may be Non Access Stratum (NAS) signaling, RRC layer signaling, Packet Data Convergence Protocol (PDCP) layer signaling, Radio Link Control (RLC) layer signaling, Media Access Control (MAC) layer signaling, or Physical Layer (PHY) signaling. The base station generates control signaling bearing one suspend information, which may be NAS signaling, RRC layer signaling, PDCP layer signaling, RLC layer signaling, MAC layer signaling, or PHY signaling. For example, if the control signaling is MAC layer signaling, the suspend information may be included in a MAC Control Element (CE). This control instruction does not necessarily involve switching between RRC_CONNECTED and RRC_INACTIVE. In other words, when a receiving device receives an MBS, it suspends each of the MRBs indicated by the suspend message in the control instruction, but the receiving device at this time may enter the RRC_INACTIVE state. In other words, the control instruction or RRCRelease message at this time may indicate that the receiving device that received the MBS has entered the RRC_INACTIVE state, or may indicate that the receiving device that received the MBS remains in the RRC_CONNECTED state.

[0060] For example, the first allocation method of the first generation method is adopted to generate the suspend information, and the suspend information is used to instruct a receiving device receiving an MBS to suspend all MRBs that are currently activated. In a current communication system, if a receiving device receiving an MBS currently activates five MRBs and the current operation requires that all active MRBs be suspended, the generated suspend information is "0". The format for currently suspending control signaling that needs to be transmitted is as follows:

[0061]

number

[0062] For example, the suspend information is generated using the first allocation method of the second generation method, and the suspend information is used to instruct a receiving device receiving an MBS to suspend all currently activated MRBs. The bits from highest to lowest in the suspend information correspond to the MRB IDs in ascending order. In a current communication system, if a receiving device receiving an MBS currently activates five MRBs and the current operation requires suspending MRB1 and MRB2 of the five MRBs, the generated suspend information is "00111". The format for currently suspending control signaling that needs to be transmitted is as follows:

[0063]

number

[0064] For example, the third generation method is used to generate suspend information, and the suspend information is used to instruct the MRB corresponding to the MRB ID to be suspended. In a current communication system, if a receiving device receiving an MBS currently has 10 MRBs established, but the current operation requires MRB1 and MRB3 to be suspended, the generated suspend information is "00010011". The format for currently suspending the control signaling that needs to be transmitted is as follows:

[0065]

number

[0066] In addition, a processing method for MBS is further provided, as shown in FIG. 2, the method includes:

[0067] S210, suspend information is received. S220: Based on the suspend information, perform one of the following: suspending all radio bearers corresponding to the MBS; not suspending all radio bearers corresponding to the MBS; or suspending some radio bearers among all radio bearers corresponding to the MBS and not suspending the remaining radio bearers among all the radio bearers.

[0068] Each radio bearer corresponding to an MBS is an MRB. Illustratively, the method illustrated in Figure 2 may be performed by a UE. Illustratively, the UE receives suspend information sent from a base station.

[0069] For example, when the UE receives the suspend information, the UE suspends all radio bearers corresponding to the MBS, or does not suspend all radio bearers corresponding to the MBS, or suspends some radio bearers and does not suspend the remaining radio bearers according to the suspend information, where each radio bearer corresponding to the MBS is an MRB.

[0070] In one embodiment of the present application, receiving suspend information includes receiving the suspend information contained in an RRCRelease message.

[0071] Exemplarily, after receiving the RRCRelease message, the UE performs a related operation of suspending or not suspending the corresponding MRB according to the value assigned to the suspend information in the RRCRelease message.

[0072] In one embodiment of the present application, receiving suspend information includes receiving the suspend information contained in a SuspendConfig message.

[0073] For example, after receiving the RRCRelease message, the UE determines whether the RRCRelease message includes a SuspendConfig message. If the RRCRelease message includes a SuspendConfig message, the UE enters the RRC_intactive state, applies a configuration corresponding to the SuspendConfig, suspends all SRBs and all DRBs except for the control SRB0, and also performs related operations of suspending or not suspending the corresponding MRBs according to the value assigned in the Suspend message.

[0074] In one embodiment of the present application, receiving suspend information includes receiving suspend information borne by control signaling, which may be NAS signaling, or RRC layer signaling, or PDCP layer signaling, or RLC layer signaling, or MAC layer signaling, or PHY signaling.

[0075] For example, after receiving the newly introduced control instruction, the UE decodes the newly introduced signaling to obtain the suspend information contained in the newly introduced control instruction, and then performs the related operation of suspending or not suspending the corresponding MRB according to the value assigned to the suspend message. The control instruction may include other partial messages, and other steps may be performed after receiving the control instruction.

[0076] In one embodiment of the present application, all MRBs of a receiving device that receives an MBS are all MRBs that the receiving device currently has established.

[0077] In one embodiment of the present application, all MRBs of a receiving device that receives an MBS are all MRBs that the receiving device currently has active.

[0078] In an embodiment of the present application, according to the suspend information, any one of suspending all radio bearers, not suspending all radio bearers, or suspending some of all radio bearers and not suspending the remaining radio bearers of all radio bearers is performed; The total number of bits of the suspend information is 1 bit, and the 1 bit is assigned as 0 or 1, When the 1 bit is assigned with 0, all MRBs of the receiving device (i.e., the UE) that receives the MBS are suspended; When the bit is set to 1, all MRBs of the receiving device that receives the MBS are not suspended. or, When the 1 bit is assigned 0, all MRBs of the receiving device that receives the MBS are not suspended, When a 1 is assigned to the 1 bit, all MRBs of the receiving device that receives the MBS are suspended.

[0079] For example, if the received MRB message is used to indicate that all MRBs, whether suspended or not, are all MRBs currently established by the receiving device (UE), when a 0 is assigned to one bit of the suspend message, the receiving device receiving the MBS suspends all currently established MRBs, and when a 1 is assigned to one bit of the suspend message, the receiving device receiving the MBS does not suspend all currently established MRBs; alternatively, when a 0 is assigned to one bit of the suspend message, the receiving device receiving the MBS does not suspend all currently established MRBs, and when a 1 is assigned to one bit of the suspend message, the receiving device receiving the MBS suspends all currently established MRBs.

[0080] When the received MRB message is used to indicate that all suspended or unsuspended MRBs are all MRBs currently activated by the receiving device, when a 0 is assigned to a bit in the suspend message, the receiving device receiving the MBS suspends all currently activated MRBs, when a 1 is assigned to a bit in the suspend message, the receiving device receiving the MBS does not suspend all currently activated MRBs, or when a 0 is assigned to a bit in the suspend message, the receiving device receiving the MBS does not suspend all currently activated MRBs, and when a 1 is assigned to a bit in the suspend message, the receiving device receiving the MBS suspends all currently activated MRBs.

[0082] For example, if the received MRB message is used to indicate that all suspended or unsuspended MRBs are all MRBs currently established by the receiving device, when a 0 is assigned to a bit in the suspend message, the receiving device suspends the MRB corresponding to that bit among the MRB IDs of all currently established MRBs, and when a 1 is assigned to a bit in the suspend message, the receiving device has not suspended the MRB corresponding to that bit among the MRB IDs of all currently established MRBs; or when a 0 is assigned to a bit in the suspend message, the receiving device has not suspended the MRB corresponding to that bit among the MRB IDs of all currently established MRBs, and when a 1 is assigned to a bit in the suspend message, the receiving device has suspended the MRB corresponding to that bit among the MRB IDs of all currently established MRBs.

[0083] When the received MRB message is used to indicate that all suspended or unsuspended MRBs are all MRBs currently activated by the receiving device, when a 0 is assigned to a bit in the suspend message, the receiving device suspends the MRB corresponding to that bit in the MRB IDs of all MRBs currently activated by the receiving device, and when a 1 is assigned to a bit in the suspend message, the receiving device does not suspend the MRB corresponding to that bit in the MRB IDs of all MRBs currently activated by the receiving device, or when a 0 is assigned to a bit in the suspend message, the receiving device does not suspend the MRB corresponding to that bit in the MRB IDs of all MRBs currently activated by the receiving device, and when a 1 is assigned to a bit in the suspend message, the receiving device suspends the MRB corresponding to that bit in the MRB IDs of all MRBs currently activated by the receiving device.

[0143] The present application also provides a computer-readable storage medium storing program instructions that, when executed by a computer, perform the above-described method for processing an MBS.

[0144] The present application also provides the following examples. Example 1: This embodiment generates suspend information, which is used to instruct all radio bearers MRB corresponding to the MBS to be suspended.

[0145] The generated suspend message has the format: The number of bits is 1, The value is 0 / 1.

[0146] When the 1 bit is assigned with 0, the suspend information instructs to suspend the MRB. Preferably, the suspend information instructs to suspend all currently established MRBs and / or all currently activated MRBs in the current communication system; When the 1 bit is assigned with 1, the suspend information instructs not to suspend the MRB. Preferably, the suspend information instructs not to suspend all currently established MRBs and / or all currently activated MRBs in the current communication system; or, When the 1 bit is assigned with 1, the suspend information instructs to suspend the MRB. Preferably, the suspend information instructs to suspend all currently established MRBs and / or all currently activated MRBs in the current communication system; When the 1 bit is assigned with 0, the suspend information instructs not to suspend the MRB. Preferably, the suspend information instructs not to suspend all currently established MRBs and / or all currently activated MRBs in the current communication system.

[0147] The information carrier carrying this suspend message may be any one of the following, but is not limited to:

[0148] By including suspend information in the RRCRelease message, or By including the suspend information in the SuspendConfig message, or The suspend information is borne by control signaling, where the control signaling may be NAS signaling, or RRC layer signaling, or PDCP layer signaling, or RLC layer signaling, or MAC layer signaling, or PHY signaling. Optionally, if the control signaling is MAC layer signaling, the suspend information may be implemented in the MAC CE; or The suspend information is agreed upon by the protocol and is a constant value, so there is no need to send this message.

[0149] The operation of a transmitting device such as a Radio Access Network (RAN) is as follows.

[0150] If the suspend information is borne by the RRCRelease message or the SuspendConfig message or the control signaling, the transmitting device generates the suspend information and transmits the suspend information via the corresponding signaling carrier; or If the suspend information is agreed to a fixed value by the protocol, the base station does not need to generate additional suspend information.

[0151] The operation of a receiving device such as a UE is as follows. Depending on the value assigned to the suspend information, the receiving device suspends all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device, or does not suspend all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device.

[0152] For example, when suspend information is generated using the first allocation method, after receiving the suspend information, the receiving device: The receiving device suspends all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device if the suspend information bit is assigned a 0; If a 1 is assigned to the suspend information bit, the receiving device does not suspend all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device.

[0153] When the suspend information is generated using the second allocation method, after receiving the suspend information, the receiving device: If the suspend information bit is assigned a value of 1, the receiving device suspends all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device; If a 0 is assigned to the suspend information bit, the receiving device will not suspend all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device.

[0154] Preferably, the receiving device may indicate the suspend and / or non-suspend status to the PDCP layer and / or multiple protocol layers below the PDCP layer of the receiving device, and in response, the receiving device may perform subsequent operations such as parameter reset, message clear, count from zero, etc.

[0155] Example 2: This embodiment generates suspend information, which is used to instruct the radio bearer MRB corresponding to the MBS to be suspended.

[0156] The generated suspend message has the format: The number of bits may be the number of all MRBs currently established by the receiving device, or may be the number of all MRBs currently activated by the receiving device.

[0157] If the total number of bits in the suspend message is equal to the total number of MRBs currently established by the receiving device, All bits in the suspend message, which are ordered from top to bottom or bottom to top, correspond one-to-one to all MRBs currently established by the receiving device, which are ordered in ascending or descending order of MRB ID.

[0158] If the total number of bits in the suspend message is equal to the total number of MRBs currently activated by the receiving device, And there is a one-to-one correspondence between all bits in the suspend message, which are ordered from top to bottom or bottom to top, and all MRBs currently activated by the receiving device, which are ordered in ascending or descending order of MRB ID.

[0159] For each bit, The value is 0 / 1.

[0160] When the bit is assigned with 0, the suspend information instructs to suspend the MRB corresponding to this bit according to the above-mentioned corresponding method; When the bit is assigned a value of 1, the suspend information indicates that the MRB corresponding to this bit is not to be suspended according to the above-mentioned correspondence scheme.

[0161] or, When the bit is assigned with 1, the suspend information instructs to suspend the MRB corresponding to this bit according to the above-mentioned corresponding method; When the bit is assigned a 0, the suspend information indicates that the MRB corresponding to this bit is not to be suspended according to the above-mentioned correspondence scheme.

[0162] The information carrier for transmitting this suspend message may be any of the following, but is not limited to some of the following:

[0163] By including suspend information in the RRCRelease message, or By including the suspend information in the SuspendConfig message, or The suspend information is carried by control signaling, where the control signaling can be NAS signaling, or RRC layer signaling, or PDCP layer signaling, or RLC layer signaling, or MAC layer signaling, or PHY signaling. Preferably, if the control signaling is MAC layer signaling, the suspend information can be implemented in MAC CE; or The suspend information is agreed upon by the protocol and is a constant value, so there is no need to send this message.

[0164] The operation of a transmitting device such as a RAN is as follows. If the suspend information is borne by an RRCRelease message or a SuspendConfig message or control signaling, the transmitting device generates the suspend information and transmits the suspend information through the corresponding signaling carrier; or if the suspend information is agreed upon by the protocol and is a fixed value, the base station does not need to generate additional suspend information.

[0165] The operation of a receiving device such as a UE is as follows. For each bit in the suspend information, the receiving device suspends or does not suspend the MRB corresponding to that bit in accordance with the above-described correspondence method, depending on the value assigned to the bit.

[0166] For example, when suspend information is generated using the first allocation method, after receiving the suspend information, the receiving device: When the bit is assigned a value of 0, the receiving device suspends the MRB corresponding to the bit according to the above-described correspondence method; When the bit is assigned a value of 1, the receiving device does not suspend the MRB corresponding to the bit according to the above-mentioned correspondence method; When the suspend information is generated using the second allocation method, after receiving the suspend information, the receiving device: When the bit is assigned a value of 1, the receiving device suspends the MRB corresponding to the bit according to the above-described correspondence method; When the bit is assigned 0, the receiving device does not suspend the MRB corresponding to the bit according to the above-mentioned correspondence method.

[0167] Preferably, for each MRB indicated in the MRB ID list in the suspend information, if the receiving device has established the MRB and the MRB is currently in an active state, the MRB is suspended. If the receiving device has not established the MRB or the MRB is not in an active state, the MRB ID is ignored.

[0168] Preferably, the receiving device may indicate the suspend and / or non-suspend status to the PDCP layer and / or multiple protocol layers below the PDCP layer of the receiving device, and perform subsequent operations such as parameter reset, message clear, and counting from zero accordingly.

[0169] Example 3 This embodiment generates suspend information, which is used to instruct the radio bearer MRB corresponding to the MBS to be suspended.

[0170] The generated suspend message has the format: The number of bits is the number of MRB IDs that indicate whether the MRB is suspended or not based on the suspend information. Preferably, the number may include a value indicating the total number of MRB IDs included in the suspend information.

[0171] The value is a list of MRB IDs. The generated suspend information includes one or more MRB IDs to instruct the receiving device to suspend the MRBs corresponding to the MRB IDs included in the suspend information.

[0172] The information carrier that carries this suspend message may be any of the following, but is not limited to some of the following:

[0173] By including suspend information in the RRCRelease message, or By including the suspend information in the SuspendConfig message, or The suspend information is carried by control signaling, where the control signaling can be NAS signaling, or RRC layer signaling, or PDCP layer signaling, or RLC layer signaling, or MAC layer signaling, or PHY signaling. Preferably, if the control signaling is MAC layer signaling, the suspend information can be implemented in MAC CE; or The suspend information is agreed upon by the protocol and is a constant value, so there is no need to send this message.

[0174] The operation of a transmitting device such as a RAN is as follows. If the suspend information is borne by the RRCRelease message or the SuspendConfig message or the control signaling, the transmitting device generates the suspend information and transmits the suspend information via the corresponding signaling carrier; or If the suspend information is agreed to a fixed value by the protocol, the base station does not need to generate additional suspend information.

[0175] The operation of a receiving device such as a UE is as follows. The receiving device suspends each MRB indicated in the MRB ID list included in the suspend information according to the MRB ID included in the suspend information.

[0176] For each MRB indicated in the MRB ID list in the suspend information, if the receiving device has established the MRB and the MRB is currently in an active state, it suspends the MRB.

[0177] If the receiving device has not established the MRB or if the MRB is not in an active state, the MRB ID is ignored.

[0178] Preferably, the receiving device may indicate the suspend and / or non-suspend status to the PDCP layer and / or multiple protocol layers below the PDCP layer of the receiving device, and perform subsequent operations such as parameter reset, message clear, and counting from zero accordingly.
