Description

[Technical field]

[0001] This application claims priority to a Chinese patent application filed with the China Patent Office on March 30, 2022 and 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 consideration of signaling overhead and power consumption in addition to the RRC_IDLE and RRC_CONNECTED states of Long Term Evolution (LTE). When a user is in the RRC_INACTIVE state, it not only reduces power consumption but also allows the user to quickly access the network, meeting the high-speed 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. In addition, 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 technology does not relate to operational rules regarding the MBS, such as whether or not the radio bearer of the MBS needs to be suspended, the time to suspend the radio bearer of the MBS, and how to suspend the radio bearer of the MBS.

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

[0021] The present application solves the problems in the related art by using a processing method, a receiving device and a transmitting device for MBS, and introduces suspend information for a receiving device (i.e., a UE) receiving an MBS to suspend or not suspend a corresponding radio bearer, thereby improving the continuity and scheduling flexibility of the MBS, optimizing network resources, and reducing the power consumption of the UE, thereby improving system performance and improving user experience. The suspend information of the present application may be suspend information newly generated by a base station or may be agreed upon by a protocol.

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

[0023] S110, generating suspend information and sending 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 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] Exemplarily, the method shown in Fig. 1 is performed by a base station. Exemplarily, the base station sends suspend information to a UE, instructing the UE to perform any 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 of all radio bearers corresponding to an MBS and not suspending the remaining radio bearers of all the radio bearers corresponding to an MBS.

[0026] Exemplarily, the base station transmits suspend information to the UE that has received the MBS. The present 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 when the suspend information is received, and further improves the continuity and scheduling flexibility of the MBS, optimizes network resources, and reduces the power consumption of the UE, 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 all MRBs of the receiving device receiving the MBS to be suspended, and when the 1 bit is assigned a 1, the suspend information instructs all MRBs of the receiving device receiving the MBS not to be suspended; alternatively, the second allocation method is such that when the 1 bit is assigned a 0, the suspend information instructs all MRBs of the receiving device receiving the MBS not to be suspended, and when the 1 bit is assigned a 1, the suspend information instructs all MRBs of the receiving device receiving the MBS to be suspended.

[0031] A first method for generating suspend information is provided, 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 that the receiving device receiving the MBS has suspended 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 does not suspend all currently established MRBs or that the receiving device receiving the MBS does not suspend 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 does not suspend all currently established MRBs or that the receiving device receiving the MBS does not suspend 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 that the receiving device receiving the MBS has suspended all currently activated MRBs.

[0032] For example, when a receiving device receiving an MBS currently has 10 MRBs established, currently has 5 MRBs activated, and currently has 5 MRBs inactive, and the current operation is required to suspend all activated MRBs, the suspend information indicates whether the receiving device receiving an MBS should suspend or not suspend all currently established MRBs. In order to suspend all 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 " and if the suspend information indicates that the receiving device receiving the MBS suspends all currently established MRBs so as to realize the current suspend request, and 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, thereby realizing the current suspend request.

[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 based on the order 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 based on the ascending or descending order of the MRB identifier (identifier, ID). For each bit of the suspend information, the first allocation method is that when the bit is assigned with 0, the suspend information indicates that the MRB corresponding to the bit is suspended, and when the bit is assigned with 1, the suspend information indicates that the MRB corresponding to the bit is not suspended, or the second allocation method is that when the bit is assigned with 0, the suspend information indicates that the MRB corresponding to the bit is not suspended, and when the bit is assigned with 1, 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 receiving the MBS, and all bits based on the order from the most significant bit to the least significant bit or from the least significant bit to the most significant bit have a one-to-one correspondence with all MRBs based on the ascending or descending order of the MRB ID, i.e., 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 bit is assigned to each bit of the suspend information, and when a bit is assigned a 0, it indicates that the suspend information is suspending the MRB corresponding to that bit, and when a bit is assigned a 1, it indicates that the suspend information is not suspending the MRB corresponding to that bit.In the second allocation method, a bit is assigned to each bit of the suspend information, and when a bit is assigned a 0, it indicates that the suspend information is not suspending the MRB corresponding to that bit, and when a bit is assigned a 1, it indicates that the suspend information is suspending the MRB corresponding to that bit.

[0036] All MRBs of the receiving device receiving the MBS may be all MRBs currently established by the receiving device, or may be all MRBs currently activated by the receiving device. In other words, if the total number of bits of the suspend information is the number of all MRBs currently established by the receiving device receiving the MBS, all bits based on the order 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 currently established by the receiving device receiving the MBS based on the ascending or descending order of the MRB ID, and when each bit in the suspend information is assigned with 0 or 1, the suspend information indicates whether or not to suspend the MRB corresponding to the bit among all MRBs currently established by the receiving device receiving the 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, then 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 IDs, and when each bit in the suspend information is assigned with 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 MRBs established, with MRB IDs being MRB1, MRB2, MR3, ..., MRB10, currently has 5 MRBs activated, with MRB IDs being MRB1, MRB2, MRB3, MRB4, MRB5, currently has 5 MRBs inactive, with MRB IDs being MRB6, MRB7, MRB8, MRB9, MRB10, and the current operation request is to suspend MRB1 and MRB2, if the total number of bits of the generated suspend information is the number of all MRBs currently established by the receiving device receiving an MBS and 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 adopts the above-mentioned second allocation method, the suspend information is "1100000000" (the bits correspond to the ascending order of the MRB ID from the top to the bottom) or "0000000011" (the bits correspond to the descending order of the MRB ID from the top to the 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 adopts the above-mentioned first allocation method, the suspend information is "00111" (the bits correspond to the ascending order of the MRB ID from the top to the bottom) or "11100" (the bits correspond to the descending order of the MRB ID from the top to the 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 high to low) or "00011" (the bits correspond to the MRB IDs in descending order from high to low).

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

[0039] A third method for generating suspend information is provided, in which 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 of the suspend information is not fixed, but depends on the actual needs, and the MRB corresponding to the MRB ID included in the suspend information is the MRB for which the suspend information requests a suspend instruction. For example, a receiving device currently receiving an MBS currently has 16 MRBs established, and the MRB IDs are MRB1, MRB2, ..., MRB16 in ascending order, and each MRB ID occupies 4 bits and is represented in hexadecimal. When the suspension of MRB1 and MRB3 is requested, the suspend information includes "0001" and "0011", and the suspend information may be represented as "00010011" to indicate the suspension of MRB1 and MRB3. In order to avoid confusion between the suspend information and other information, the suspend information may include the number of MRB IDs included, i.e., in the above case, 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, "1" may be used to indicate that there is another MRB ID after the MRB ID, and "0" may be used to indicate that there is no another MRB ID after the MRB ID, i.e., "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 transmits the RRCRelease message, thereby 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 is transmitted by being included in the RRCRelease message.

[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 the receiving device receiving the MBS to suspend all currently activated MRBs, and in the current communication system, if the UE receiving the MBS currently activates 5 MRBs and the current operation requires the receiving device receiving the MBS to suspend all activated MRBs, the generated suspend information is '0'. The format of the currently suspend RRCRelease message that needs to be sent is as follows:

[0044]

number

[0045] In addition to the part representing the 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 first allocation method of the second generation method is adopted to generate the suspend information, and the suspend information is used to instruct the receiving device receiving the MBS to suspend all MRBs currently activated, and the bits from the most significant to the least significant in the suspend information correspond to the MRB IDs in ascending order, and in the current communication system, if the receiving device receiving the MBS currently activates five MRBs and the current operation requires MRB1 and MRB2 of the five MRBs to be suspended, the suspend information generated is "00111". The format of the RRCRelease message that needs to be sent to suspend the currently activated MRBs is as follows:

[0047]

number

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

[0049]

number

[0050] In one embodiment of the present application, the suspend information may be included in the SuspendConfig message. For example, the generated suspend information is included in the SuspendConfig message, and the SuspendConfig message is sent in the RRCRelease message, so that the receiving device that receives the 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, and in a current communication system, if a receiving device receiving an MBS currently activates 5 MRBs and the current operation requires all activated MRBs to 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 by adopting 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, and the bits from the most significant to the least significant in the suspend information correspond to the MRB IDs in ascending order, and in a current communication system, if a receiving device receiving an MBS currently activates five MRBs and the current operation requires MRB1 and MRB2 of the five MRBs to be suspended, the suspend information generated is "00111". The format of the currently suspended RRCRelease message that needs to be sent is as follows:

[0056]

number

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

[0058]

number

[0059] In one embodiment of the present application, the suspend information may be further borne by a control signaling, and the control signaling may be a Non Access Stratum (NAS) signaling, or an RRC layer signaling, or a Packet Data Convergence Protocol (PDCP) layer signaling, or a Radio Link Control (RLC) layer, or a Media Access Control (MAC) layer signaling, or a Physical Layer (PHY) signaling. The base station generates a control signaling bearing one suspend information, and the control signaling may be a NAS signaling, or an RRC layer signaling, or a PDCP layer signaling, or an RLC layer signaling, or a MAC layer signaling, or a PHY signaling. For example, if the control signaling is a 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 that has received an MBS receives the control instruction, 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; i.e., the control instruction or RRCRelease message at this time may indicate that the receiving device that has received the MBS has entered the RRC_INACTIVE state, or may indicate that the receiving device that has 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 currently activated, and in a current communication system, if a receiving device receiving an MBS currently activates 5 MRBs and the current operation requires all active MRBs to be suspended, the generated suspend information is "0". The format of currently suspending the control signaling that needs to be transmitted is as follows:

[0061]

number

[0062] For example, the suspend information is generated by adopting 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, and the bits from the most significant to the least significant in the suspend information correspond to the MRB IDs in ascending order, and 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 suspend information generated is "00111". The format for currently suspending the control signaling that needs to be transmitted is as follows:

[0063]

number

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

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, executes one of suspending all radio bearers corresponding to the MBS, not suspending all radio bearers corresponding to the MBS, and suspending some of the radio bearers among all the 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. Exemplarily, the method shown in Figure 2 may be performed by a UE. Exemplarily, the UE receives suspend information sent from a base station.

[0069] Exemplarily, 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 a 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 a 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] Exemplarily, 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 an RRC_intactive state, applies a configuration corresponding to the SuspendConfig, suspends all SRBs and all DRBs except the control SRB0, and also performs related operations of suspending or not suspending the corresponding MRBs according to the values ​​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] Exemplarily, after receiving the newly introduced control instruction, the UE decodes the newly introduced signaling to obtain the suspend information included 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.

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

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

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

[0146] When the 1 bit is assigned a value of 0, the suspend information instructs the MRB to be suspended. Preferably, the suspend information instructs the MRB to be suspended in the current communication system, all currently established MRBs and / or all currently activated MRBs; 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 one bit is assigned a value of 1, the suspend information instructs the MRB to be suspended. Preferably, the suspend information instructs the MRB to be suspended in the current communication system, all currently established MRBs and / or all currently activated MRBs; When the 1 bit is assigned a value of 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 the following:

[0148] By including suspend information in the RRCRelease message, or By including the suspend information in a SuspendConfig message, or The suspend information is borne by a 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. Optionally, if the control signaling is MAC layer signaling, the suspend information can be realized 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 the 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 will not suspend all MRBs currently established by the receiving device and / or all MRBs currently activated by the receiving device.

[0153] When the second allocation method is used to generate suspend information, after receiving the suspend information, the receiving device The receiving device, if the suspend information bit is assigned a value of 1, 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 take subsequent actions such as resetting parameters, clearing messages, counting from zero, etc.

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

[0156] The format of the suspend message that is generated is: 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, And all bits in the suspend message, which are ordered from top to bottom or bottom to top, correspond one-to-one with all MRBs currently established by the receiving device, which are ordered in ascending or descending order of MRB IDs.

[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, based on top-to-bottom or bottom-to-top order, and all MRBs currently activated by the receiving device, based on ascending or descending order of MRB IDs.

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

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

[0161] or, When the bit is assigned a value of 1, the suspend information instructs the MRB corresponding to this bit to be suspended according to the above-mentioned corresponding manner; When the bit is assigned a 0, the suspend information indicates not to suspend the MRB corresponding to this bit according to the corresponding scheme described above.

[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 a SuspendConfig message, or The suspend information is borne 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 realized 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.

[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 a fixed value agreed upon by the protocol, 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-mentioned response method depending on the value assigned to the bit.

[0166] For example, when the 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-mentioned correspondence method; When the receiving device is assigned a value of 1 to the bit, the receiving device does not suspend the MRB corresponding to the bit according to the above-mentioned corresponding method; When the second allocation method is used to generate suspend information, 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-mentioned correspondence method; When the bit is assigned a value of 0, the receiving device does not suspend the MRB corresponding to the bit according to the above-mentioned correspondence scheme.

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

[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, counting from zero, etc. accordingly.

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

[0170] The format of the suspend message that is generated is: The number of bits is the number of MRB IDs that indicate suspend or non-suspend from the suspend information. Preferably, the number of bits 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 MRB corresponding to the MRB ID included in the suspend information.

[0172] The information carrier carrying 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 a SuspendConfig message, or The suspend information is borne 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 realized 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.

[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 establishes 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, counting from zero, etc. accordingly.
