Description

Technical Field

[0001] (Cross - reference to related applications) This disclosure is based on Chinese Patent Application No. 202310586212.1 filed on May 23, 2023, claims the priority of the Chinese patent application, and the entire content thereof is incorporated herein by reference.

[0002] This disclosure belongs to the field of wireless communication technology, and particularly relates to an information transmission method and apparatus, a terminal, a network device, and a readable storage medium.

Background Art

[0003] Through the joint configuration of Conditional Handover (CHO) and Conditional PSCell Addition (CPA) / Conditional PSCell Change (CPC), it is necessary to set CHO for the Master Cell Group (MCG) and CPA or CPC for the Secondary Cell Group (SCG) for the User Equipment (UE). The UE can utilize dual connectivity only when both CHO and CPA / CPC are effective. Ideally, the goal of network configuration is to ensure that the events corresponding to CHO and CPA / CPC are satisfied simultaneously, so that the UE can complete the handover of the Primary Cell (PCell) and execute dual connectivity using the Primary - Secondary Cell (PSCell) at the same time. However, in reality, due to the non - rationality of the UE's mobility and the operator's network optimization configuration, it is highly likely that the events corresponding to CHO and CPA / CPC are not satisfied simultaneously. Therefore, how the network configures reasonable CHO and CPA / CPC events is an urgent problem to be solved.

[0030] The following describes the technical solutions in the embodiments of this disclosure clearly and completely with reference to the accompanying drawings. The embodiments described are part of the disclosure, but not all embodiments. All other embodiments that a person skilled in the art could obtain without creative effort based on the embodiments of this disclosure are within the scope of this disclosure.

[0031] The terms “first,” “second,” etc., in the specification and claims of this disclosure are used to distinguish similar subjects and are not used to describe any particular order or sequence. The data used in this manner should be understood to be interchangeable in appropriate contexts and to allow embodiments of this disclosure to be carried out in an order other than those illustrated or described herein, and subjects distinguished by “first,” “second,” etc., are usually one category and not limited to the number of subjects. For example, there may be one or more subjects in the first category. Furthermore, “and / or” in the specification and claims means that there is at least one connected subject, and the letter “ / ” generally indicates that the preceding and following related subjects are in an “or” relationship.

[0032] First, the relevant technologies related to this disclosure are described below.

[0033] CHO is a mechanism for enhancing handover robustness. To address the problem of the UE being unable to successfully complete the handover process when channel quality between the UE and the service cell deteriorates rapidly (e.g., during high-speed movement or in high-frequency band scenarios), the base station can configure the UE to trigger measurement reports at lower thresholds, and transmit higher thresholds, such as A3 or A5 events that trigger a handover, via CHO commands, which may also include the random access resources the UE will use in the target cell. Once the handover event is met, the UE initiates the random access process to the target cell. The source base station can configure the UE for conditional handovers to multiple target cells.

[0034] Similarly, in dual connectivity scenarios, for conditional PSCell addition (CPA) and conditional PSCell modification (CPC), the network-side device pre-configures information with the UE. The network-side device may include a Master Node (MN) (for CPA) and an MN or Secondary Node (SN) (for CPC), and the configuration may include the cell identifier of one or more candidate primary / secondary cells (PSCells), the corresponding conditional addition or modification event (e.g., one or two of A3, A4, and A5 events), the Cell Radio Network Temporary Identifier (C-RNTI) used by the UE for the candidate PSCell, and a dedicated random access resource. If the UE evaluates that a particular candidate PSCell cell meets the trigger conditions, it adds that candidate PSCell or changes the target cell to that candidate PSCell.

[0035] To enable the UE to quickly utilize dual connectivity after MCG handover and improve the UE's data rate, we propose a mechanism for jointly setting up a CHO for the MCG (or PCell) and a CPA / CPC for the SCG (or PSCell) for the UE. Furthermore, to improve the effectiveness of dual connectivity and avoid unnecessary CPA / CPC operations, the UE does not perform CPA / CPC operations before the MCG's CHO is triggered (or before the MCG's CHO settings are applied). However, to enable the UE to quickly apply dual connectivity, the evaluation of candidate PCells for CHO operations and candidate PSCells for CPA / CPC operations can be performed simultaneously.

[0036] The following describes in detail, with reference to the drawings, the information transmission method and apparatus, terminal, network device, and readable storage medium according to the embodiments of this disclosure, based on specific examples and their application scenarios.

[0037] As shown in Figure 1, at least one embodiment of the present disclosure provides an information transmission method applicable to a terminal, the method comprising step 101.

[0038] In step 101, first information is transmitted to the network device. The first information is used to indicate a conditional handover (CHO) and / or a first operation. The first operation is a conditional PSCell addition (CPA) and / or a conditional PSCell modification (CPC).

[0039] Optionally, the first information is used by the network device to optimize target parameters corresponding to the CHO and / or first operation, the target parameters including a trigger event and / or parameters corresponding to the trigger event.

[0040] For example, the trigger event includes, but is not limited to, at least one of the A3, A5, and B1 events. For example, the parameters corresponding to the trigger event may include the offset a3-Offset, hysteresis amount, time to trigger (TimeToTrigger, TTT) corresponding to the A3 event, and the thresholds a5-Threshold1, a5-Threshold2, hysteresis amount, and TTT corresponding to the A5 event.

[0041] In one embodiment, the first information includes at least one of the following A101 to A113.

[0042] A101: The order of event satisfaction for CHO and event satisfaction for the first operation.

[0043] Furthermore, the order in which the CHO's event is satisfied and the first operation's event is satisfied may be at least one of the following: the CHO's event is satisfied first; the CHO's event is satisfied first; the first operation's event is satisfied first; the first operation's event is satisfied first; the CHO's event is satisfied later; the CHO's event is satisfied later; the first operation's event is satisfied later; or the first operation's event is satisfied later.

[0044] It should be noted that the term "event satisfaction" as used in embodiments of this disclosure may also be described or expressed as "event trigger." For example, event satisfaction for a CHO is equivalent to an event trigger for a CHO. A PSCell (or SCG) corresponding to a first operation and a PCell (or MCG) corresponding to a CHO may be related (i.e., the PSCell and PCell jointly provide dual connectivity services to a terminal) or they may not be related (i.e., the PSCell jointly provides dual connectivity services to a terminal with another PCell).

[0045] In embodiments of this disclosure, PCell may be described or represented as MCG, and PSCell may be described or represented as SCG.

[0046] A102: The time difference between the event satisfaction of CHO and the event satisfaction of the first operation.

[0047] The time difference refers to the difference between the time the CHO event is satisfied and the time the first operation event is satisfied. For example, the unit of this time difference may be seconds, milliseconds, slots, subslots, orthogonal frequency division multiplexing (OFDM) symbols. The PSCell (or SCG) corresponding to the first operation and the PCell (or MCG) corresponding to the CHO may be related (i.e., the PSCell and PCell jointly provide dual connectivity services to the terminal), or they may not be related (i.e., the PSCell jointly provides dual connectivity services to the terminal with other PCells).

[0048] For example, if the CHO event in PCell 1 is satisfied first, and the CPA or CPC event in PSCell 2 is satisfied later, the time difference refers to the difference between the time the CHO event in PCell 1 is satisfied and the time the CPA or CPC event in PSCell 2 is satisfied.

[0049] A103: Target event.

[0050] Optionally, the target event includes at least one of the following A1031 to A1032.

[0051] A1031: An event corresponding to a first operation of at least one PSCell or SCG corresponding to the first PCell or first MCG, which is satisfied before or when the event of CHO of the first PCell or first MCG is satisfied.

[0052] The first PCell refers to a target cell that satisfies the CHO event and can also be called a candidate PCell. The first MCG refers to a cell group that contains a target cell that satisfies the CHO event and can also be called a candidate MCG.

[0053] For example, the case in question can be understood as follows: The target event is an event corresponding to the CPA and / or CPC of at least one PSCell or SCG corresponding to the first PCell or first MCG, which was satisfied before the event of the CHO of the first PCell or first MCG was satisfied. Or, the target event is an event corresponding to the CPA and / or CPC of at least one PSCell or SCG corresponding to the first PCell or first MCG, which was satisfied at the time the event of the CHO of the first PCell or first MCG was satisfied.

[0054] Furthermore, at least one PSCell or SCG corresponding to a first PCell or first MCG can also be understood as at least one PSCell or SCG associated with the first PCell or first MCG. In other words, one PCell corresponds to or is associated with one or more PSCells, and one MCG corresponds to or is associated with one or more SCGs.

[0055] For example, if Cell 1 is the primary cell accessed by the terminal after a CHO, or the primary cell where the terminal first experiences a CHO, and the event corresponding to the CPA or CPC of PSCell2 is satisfied before the CHO event of Cell 1 is satisfied, and PSCell2 is a candidate PSCell associated with Cell 1, then the terminal needs to record the event corresponding to the CPA or CPC of PSCell2.

[0056] A1032: An event corresponding to a first operation of a PSCell (PScell) or SCG that is satisfied before or when the CHO event of a first PCell or first MCG is satisfied. The PSCell or SCG of the satisfied first operation corresponds to a second PCell (primary cell) or second MCG.

[0057] Furthermore, the second PCell refers to a target cell in which the CHO event has not been satisfied, and can be understood as a candidate primary cell of the terminal. The second MCG refers to a cell group in which a target cell in which the CHO event has not been satisfied exists, and can also be called a candidate MCG.

[0058] What needs to be explained here is that the first PCell and the second PCell are different cells. The first PCell is the target primary cell that first satisfies the CHO event, while the second PCell is a target primary cell other than the one that first satisfies the CHO event. For example, if a terminal has three target primary cells, primary cell A, primary cell B, and primary cell C, and primary cell C satisfies the CHO event first, then primary cell C is the first PCell, and primary cells A and B are the second PCells.

[0059] For example, in this case, the target event can be understood as the event corresponding to the CPA and / or CPC of a candidate PSCell or candidate SCG corresponding to another primary cell or other MCG, other than the first PCell or first MCG, which is satisfied before the CHO event of the first PCell or first MCG is satisfied. Alternatively, the target event can be understood as the event corresponding to the CPA and / or CPC of a candidate PSCell or candidate SCG corresponding to another primary cell or other MCG, other than the first PCell or first MCG, which is satisfied when the CHO event of the first PCell or first MCG is satisfied.

[0060] For example, if Cell 1 is the primary cell accessed by the terminal after a CHO, or the primary cell where the terminal first experiences a CHO, and the event corresponding to the CPA or CPC of PSCell3 is satisfied before the CHO event of Cell 1 is satisfied, and PSCell3 is a candidate PSCell corresponding to another primary cell other than Cell 1, then the terminal needs to record the event corresponding to the CPA of PSCell3.

[0061] A104: Identification information for at least one candidate PSCell corresponding to the target event.

[0062] For example, the identification information may be a cell ID (e.g., a Physical Cell Identifier (PCI) or a Globally Unique Cell Identifier (NR Cell Global Identifier, NCGI)) or an index corresponding to the cell.

[0063] Typically, this case applies to A1031 and A1032 above.

[0064] A105: Identification information for the candidate primary cell corresponding to the target event. For example, this identification information may be a cell ID (e.g., PCI or NCGI) or an index corresponding to the cell.

[0065] Typically, this case applies to A1031 and A1032 above.

[0066] A106: The order in which the target events are fulfilled.

[0067] Optionally, the order may be the order in which events in one or more PSCells (or SCGs) related to the PCell (or MCG) in which the CHO event is satisfied or triggered are satisfied or triggered. For example, if the CPA or CPC events in PSCell2, PSCell3, and PSCell4 related to PCell1 are satisfied before or at the same time as the CHO event in PCell1 is satisfied, the order in which the target event is satisfied is the CPA or CPC event in PSCell2, the CPA or CPC event in PSCell3, and the CPA or CPC event in PSCell4.

[0068] Optionally, the order may be the order in which one or more PSCell (or SCG) events unrelated to the PCell (or MCG) that satisfies or triggers the CHO event. For example, if the CPA or CPC events of PSCell 5 and PSCell 6 related to PCell 2 are satisfied before or when the CHO event of PCell 1 is satisfied, the order in which the target event is satisfied is the CPA or CPC event of PSCell 5, then the CPA or CPC event of PSCell 6. Furthermore, for example, if the CHO event in PCell 1 is satisfied before or at the time of satisfaction, and the CPA or CPC events in PSCell 5 and PSCell 6 related to PCell 2 are satisfied before or after, and the CPA or CPC event in PSCell 7 related to PCell 3 is satisfied, then the order in which the target events are satisfied is the CPA or CPC event in PSCell 5, the CPA or CPC event in PSCell 6, and the CPA or CPC event in PSCell 7.

[0069] Optionally, the order may be the order in which events of one or more PSCells (or SCGs), whether related to or unrelated to the PCell (or MCG) that satisfies or triggers the CHO event. For example, if the CHO event in PCell 1 is satisfied before or at the same time as the CPA or CPC events in PSCell 2, PSCell 3, and PSCell 4 related to PCell 1 are satisfied before, after, or simultaneously (for example, the CPA or CPC events in PSCell 3 and PSCell 4 are satisfied simultaneously), and the CPA or CPC events in PSCell 5 and PSCell 6 related to PCell 2 are satisfied before, after, and the event satisfaction in PSCell 5 is before the CPA or CPC event in PSCell 3, then the order in which the target events are satisfied is the CPA or CPC event in PSCell 2, the CPA or CPC event in PSCell 5, the CPA or CPC event in PSCell 3, the CPA or CPC event in PSCell 4, and the CPA or CPC event in PSCell 6.

[0070] A107: The time difference between when the target event is fulfilled.

[0071] For example, in A106 mentioned above, the order in which the target events are satisfied is the CPA or CPC event in PSCell 2, the CPA or CPC event in PSCell 3, and the CPA or CPC event in PSCell 4. In this case, the time difference refers to the time difference from the earliest event satisfaction. For example, the time difference includes: the difference obtained by (time of event satisfaction of the CPA or CPC event in PSCell 3) - (time of event satisfaction of the CPA or CPC event in PSCell 2), and / or the difference obtained by (time of event satisfaction of the CPA or CPC event in PSCell 4) - (time of event satisfaction of the CPA or CPC event in PSCell 2). Alternatively, the time difference refers to the time difference between event satisfaction times in two adjacent cells. For example, the time difference includes: The difference obtained by (the time of event fulfillment for CPA or CPC in PSCell 3) - (the time of event fulfillment for CPA or CPC in PSCell 2), and / or the difference obtained by (the time of event fulfillment for CPA or CPC in PSCell 4) - (the time of event fulfillment for CPA or CPC in PSCell 3).

[0072] A108: The time difference between the fulfillment of the target event and the fulfillment of the event of the first PCell or MCG's CHO.

[0073] In the aforementioned A106, the order in which the target events are satisfied is the CPA or CPC event in PSCell2, the CPA or CPC event in PSCell3, the CPA or CPC event in PSCell4, and the CHO event in PCell1. For example, the time difference refers to the difference obtained by (time of CHO event satisfaction in PCell1) - (time of CPA or CPC event satisfaction in PSCell2), and / or the difference obtained by (time of CHO event satisfaction in PCell1) - (time of CPA or CPC event satisfaction in PSCell3), and / or the difference obtained by (time of CHO event satisfaction in PCell1) - (time of CPA or CPC event satisfaction in PSCell4). Alternatively, the difference obtained by (time of event satisfaction for CPA or CPC in PSCell 2) - (time of event satisfaction for CHO in PCell 1), and / or the difference obtained by (time of event satisfaction for CPA or CPC in PSCell 3) - (time of event satisfaction for CHO in PCell 1), and / or the difference obtained by (time of event satisfaction for CPA or CPC in PSCell 4) - (time of event satisfaction for CHO in PCell 1).

[0074] A109: First instruction information, which is used to indicate that the fulfillment of a target event has occurred.

[0075] A110: The cell identifier of the candidate primary cell corresponding to CHO.

[0076] A111: The cell identifier of the candidate PSCell corresponding to the first operation.

[0077] A112: An event corresponding to the satisfaction of CHO and / or the satisfaction of the first operation.

[0078] The event in question may be A3, A5, B1, etc., at will. Typically, this case also needs to include parameters corresponding to the event, such as an offset corresponding to the A3 event, a threshold corresponding to the A5 event, TTT, etc.

[0079] Furthermore, since the network does not store specific information about previously configured shared configurations for UEs, the UEs reporting this information allows the network to understand previous configurations and facilitate configuration optimization.

[0080] A113: Configuration nodes of CPC.

[0081] The configuration node may optionally be a master node (MN) or a secondary node (SN).

[0082] It's important to explain here that the only constituent nodes for CHO and CPA are MNs.

[0083] Note that the term "correspondence" mentioned in the above explanation can also be described as "association." For example, an alternative description for "identifier of at least one candidate PSCell corresponding to the target event" is "identifier of at least one candidate PSCell associated with the target event." For example, an alternative description for "an event corresponding to the satisfaction of the CHO and / or the satisfaction of the first operation" is "an event associated with the satisfaction of the CHO and / or the satisfaction of the first operation."

[0084] A relationship of association or correspondence exists between candidate primary cells or MCGs for CHOs and candidate PSCells or SCGs for CPAs / CPCs. That is, one candidate primary cell or MCG is associated with or corresponds to at least one candidate PSCell or SCG.

[0085] Furthermore, the first information can be reported voluntarily by the terminal, or it can be reported by the terminal in response to a request from the network side. In one embodiment, a specific embodiment of transmitting the first information to the network device is as follows: Receiving request information from the network device, wherein the request information is used by the network device to request a terminal to transmit the first information, and transmitting the first information to the network device based on the request information.

[0086] In other words, if a network device needs to optimize target parameters corresponding to the CHO and / or first operation, it must send a request to the terminal to have the terminal report the first information, so that the first information is reported as needed, and the signaling overhead problem caused by the terminal reporting unnecessary information can be avoided.

[0087] In one embodiment, before receiving the request information from the network device, the method further: This includes transmitting a second instruction to the network device, the second instruction being used to indicate that the first information exists at the terminal.

[0088] When a network device requests primary information from a terminal, it first needs to know if that primary information exists on the terminal side. Only if the primary information exists on the terminal will the network device request it from the terminal, thereby avoiding wasted signaling.

[0089] In one embodiment, transmitting the first information to the network device is: This includes transmitting the first information to the network device via a target message, Here, the target message includes at least one of the following B11 to B13.

[0090] B11: Wireless resource re-establishment request message.

[0091] Furthermore, the terminal may include the first information in the wireless resource re-establishment request message.

[0092] B12: Wireless link failure reported.

[0093] Furthermore, the terminal may include primary information in its wireless link failure report.

[0094] The above B11 and B12 can be understood as the terminal reporting the first information based on the existing message.

[0095] B13: First information report message.

[0096] Furthermore, this case introduces a newly defined message (which may be, for example, a newly defined Radio Resource Control (RRC) message), which is solely for reporting first information.

[0097] In one embodiment, before transmitting the first information to the network device, the method further includes receiving reporting configuration information for the first information, the reporting configuration information includes instructions for collecting or recording the first information.

[0098] In this case, the information that the terminal needs to collect is configured by the network, and for example, the reporting configuration information can be understood to include instructions to collect one or more of the items A101 to A1013 above. The terminal needs to obtain the corresponding first information based on the instructions from the network.

[0099] In one embodiment, the reporting configuration information further includes reporting conditions for the first information, wherein the reporting conditions include a threshold for the time difference between the event satisfaction of the CHO and the event satisfaction of the first operation. The reporting conditions can be understood as threshold requirements that the first information report must satisfy.

[0100] For example, if the time difference between the actual CHO and the CPA / CPC event trigger or fulfillment in the UE is greater than a threshold, the UE should record the above information; otherwise, it does not need to. This is because a small time difference indicates that the interval between the CHO event trigger and the CPA / CPC event trigger is not long.

[0101] A specific embodiment of optionally receiving the reporting configuration information for the first information includes receiving the reporting configuration information for the first information transmitted from a network management device, a trace collection entity (TCE), or a network device.

[0102] The network device may also be an MN or SN.

[0103] Furthermore, after receiving the first information, the network device performs configuration optimization of the CHO and / or the first operation based on the first information.

[0104] In one embodiment, performing configuration optimization of the CHO and / or the first operation based on the first information includes at least one of the following C11 to C13.

[0105] In C11, the parameters of the event corresponding to CHO and / or the event corresponding to the first operation are adjusted based on the order and / or time difference between the event satisfaction of CHO and the event satisfaction of the first operation.

[0106] In this case, the trigger timing of a specific event is adjusted by modifying the event or the parameter corresponding to the event, thereby ensuring that one event is triggered earlier or another later.

[0107] For example, if the CHO is triggered first, and there is a large time difference between the CHO trigger and the CPA (or CPC) trigger (this time difference may be a duration threshold obtained by the operator based on actual operational experience, e.g., 30 seconds), it indicates that the CPA (or CPC) was too late, and it took a very long time to utilize dual connectivity after the UE handover. In this case, the network side needs to adjust the events that trigger the CPA (or CPC) and / or the corresponding thresholds (e.g., adjusting the offset parameter of the A3 event lower, adjusting the parameter a5-Threshold1 of the A5 event higher, and adjusting a5-Threshold2 lower), and adjust the TTT of the CHO trigger lower so that the CPA (or CPC) operation is executed or triggered earlier. and / or, the network side should adjust the threshold of the CHO trigger so that the CHO is triggered later and executed as synchronously as possible with the CPA (or CPC) trigger.

[0108] For example, if a CPA (or CPC) is triggered first, and there is a large time lag between the CHO trigger and the CPA (or CPC) trigger, it indicates that the CPA (or CPC) is triggered too early or the CHO is triggered too late, and after the UE's PCell handover, the PSCell that previously satisfied the CPA (or CPC) may become unavailable immediately (due to relatively low SCG coverage). The network side can adjust the thresholds for CHO triggers, such as lowering the a3-Offset for A3 events, raising the a5-Threshold1 for A5 events, and lowering the a5-Threshold2, to lower the TTT of the CHO trigger, so that the CHO is triggered earlier and synchronized with the CPA (or CPC) trigger as much as possible. Alternatively, the network could adjust the events and / or corresponding thresholds that trigger a CPA (or CPC) (e.g., adjusting a3-Offset higher for A3 events, a5-Threshold1 lower for A5 events, and a5-Threshold2 higher), and adjust the TTT of the CPA / CPC trigger higher so that the execution or triggering of the CPA (or CPC) is delayed, allowing it to synchronize / coordinate with the CHO trigger.

[0109] In C12, if the first operation of at least one PSCell is triggered before the CHO trigger, the number of candidate PSCells is reduced, the threshold for the event corresponding to the first operation is adjusted, and / or the threshold for the event corresponding to the CHO is adjusted.

[0110] Furthermore, if the first operation of at least one PSCell is triggered before the CHO trigger, this can be interpreted as indicating that the CHO trigger is too late, or that the first operation of the corresponding PSCell is too early, or that there are too many candidate PSCells set. In this case, the threshold for events corresponding to the CHO should be adjusted so that the CHO is triggered earlier. And / or, reduce the number of candidate PSCells (if the time difference between the fulfillment of multiple CPA / CPC events is very small, there is no need to set so many candidate PSCells, and only the last PSCell closest to the CHO fulfillment time should be kept. For example, the PSCell that triggered the first operation can not be set as a candidate PSCell). And / or, adjust the threshold for events corresponding to the first operation so that the CHO is triggered as early as possible, or the first operation is triggered as late as possible.

[0111] In C13, if a first operation trigger related to a candidate primary cell (PCell) exists before the CHO trigger, the parameters of the event corresponding to the first operation are adjusted.

[0112] Furthermore, if a first operation trigger related to another candidate primary cell (i.e., a primary cell other than the target primary cell that first satisfies the CHO event) exists before the CHO trigger, it indicates that the CPA and / or CPC triggers related to the other candidate primary cell were triggered too early. In this case, adjust the parameters of the events corresponding to the CPA and / or CPC so that the CPA and / or CPC are triggered as late as possible, or the CHO is triggered earlier. For example, ensure that the CHO of the candidate primary cell related to the first operation is triggered earlier.

[0113] In one embodiment, the network device further determines the configuration nodes of the CPC, transmits the CPC-related information in the first information to the configuration nodes, and the configuration nodes perform optimization of the relevant configuration parameters.

[0114] This case primarily applies when the network device receiving the first information and the constituent nodes of the CPC do not match. For example, this applies when the network device receiving the first information is MN while the constituent nodes of the CPC are SN, or when the network device receiving the first information is SN while the constituent nodes of the CPC are MN.

[0115] In summary, embodiments of this disclosure propose that a terminal reports information such as the order in which CHO and CPA (and / or CPC) event satisfaction occur, the time difference between them, and configured events. This allows the network to help optimize events corresponding to CHO and events corresponding to CPA (and / or CPC), and / or corresponding parameters, thereby improving the reliability of communications.
