Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method and device for updating a system message, a storage medium, a terminal, and a base station. Background Art

[0002] In a wireless communication system, the entire network is divided into several cells, and each cell generally uses broadcasting to transmit system information so that user equipment (UE) can reside in the cell. The UE entering the cell obtains the system information of the cell by receiving broadcast messages, and then uses the configuration information in the system messages to access the network or carry out services of interest.

[0003] In the fourth generation mobile communication system, there are three types of radio resource control (RRC) messages in the broadcast messages for transmitting system information, namely, Master Information Block (MIB), System Information Block (SIB) and one or more System Information (SI, also called system message).

[0004] Among them, MIB contains important information such as cell bandwidth and system frame number; there are many types of SIBs, each SIB contains a series of system information parameters related to a certain function, and SIBs other than SIB1 are contained in different SIs; each SI contains one or more SIBs with the same scheduling requirements except SIB1.

[0005] Because the scheduling of other SIBs is placed in SIB1, the 3rd Generation Partnership Project (3GPP) originally thought that the direct extension of the SIB type could support the scheduling of SIB19 to SIB26. In other words, 3GPP originally thought that placing the scheduling information of these extended SIBs, SIB19 to SIB26, in SIB1 would not affect legacy UEs. However, in actual applications, when some legacy UEs read SIB1 that contains the scheduling information of the extended SIB, they will think that this SIB1 is wrong, and then think that this cell cannot be resident (Barred). For specific issues, please refer to protocol version R2-2008083.

[0006] 3GPP discussed this issue at the RAN2#111e meeting in August and reached a consensus: independent SI scheduling information will be used for SIB19 and later SIBs. That is, the scheduling information of the extended SIB is still carried in SIB1, but is distinguished from the scheduling information of the original SIB (i.e. SIB1-SIB18).

[0007] When the network broadcasts extended SIBs SIB19 to SIB26, if only the system messages of these extended SIBs, such as SIB24, are updated, the existing system message update mechanism is used, and the base station indicates the system message update in a paging message.

[0008] For the new version of UE, in response to the indication of system message update in the paging message, after reading the scheduling information of the original SI (used for the original SIB) and the scheduling information (SchedulingInfoExt) of the extended SI (used for scheduling the extended SIB), it can be known that SIB24 has been updated.

[0009] However, for old version UEs, after reading the scheduling information of the original SI, if they find that no system message update has occurred, it will be confusing and power-consuming for these UEs. Because old version UEs cannot recognize the newly introduced special scheduling extended SIB information element (i.e., the scheduling information of the extended SI), when the old version UEs are informed of the system message update, the useful information that the old version UEs can actually recognize in SIB1 has not changed, causing confusion for the old version UEs. Furthermore, the old version UEs do not support the corresponding functions or services of the extended SIB. Therefore, in fact, the old version UEs do not need to respond to the system message update when only the extended SIB is updated, resulting in meaningless power consumption by the old version UEs.

[0010] In summary, the existing system message update mechanism has defects, especially when the extended SIB is updated, it will seriously affect the power consumption of the old version UE. Summary of the invention

[0015] Optionally, the updating method further includes: if the paging message only includes the first update indication, determining both the first SIB type system message and the second SIB type system message as the system messages to be updated.

[0016] Optionally, the first SIB type system message includes SIB1 to SIB18, and the second SIB type system message includes extended SIB.

[0018] To solve the above technical problems, an embodiment of the present invention also provides a method for updating a system message, including: determining a first update indication and a second update indication according to the SIB type to which the system message to be updated belongs, wherein the first update indication is used to indicate whether a first SIB type system message is updated, and the second update indication is used to indicate whether a second SIB type system message is updated; generating and sending a paging message based on the first update indication and the second update indication.

[0024] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0025] On the UE side, an embodiment of the present invention provides a method for updating a system message, including: receiving a paging message; determining a system message to be updated in a first SIB type system message according to a first update indication in the paging message, wherein the first update indication is used to indicate whether the first SIB type system message is updated; determining a system message to be updated in a second SIB type system message according to a second update indication in the paging message, wherein the second update indication is used to indicate whether the second SIB type system message is updated.

[0026] Compared with the existing technical solution of indicating the update of two SIB types of system messages through the same system message update indication, the solution of the present invention can realize the update of system messages in a more targeted manner, and will not affect the old version UE when updating and expanding the SIB, thereby reducing the meaningless power consumption of the old version UE. Specifically, an indication information is added to the paging message specifically for indicating the update status of the second SIB type system message. That is, the update status of the two SIB types of system messages is indicated separately, so that both the new and old version UEs can perform reasonable update operations according to the corresponding indication information. For example, the first update indication enables both the new and old version UEs to update the first SIB type system message in a timely manner. For another example, the second update indication can prevent the old version UE from performing meaningless system message update operations and wasting power consumption, while ensuring that the new version UE can update the second SIB type system message in a timely manner.

[0027] Taking the new version UE as an example, the system message to be updated in the first SIB type system message is determined according to the first update indication, and the system message to be updated in the second SIB type system message is determined according to the second update indication. Thus, the new version UE can clearly know whether the original SIB and the extended SIB are updated.

[0028] Taking an old version UE as an example, if the first update indication determines that the first SIB type system message has not been updated, and the second update indication determines that the second SIB type system message has been updated, the old version UE can confirm that it does not need to perform an update operation, thereby making it possible to save meaningless power consumption of the UE.

[0029] On the network side, an embodiment of the present invention also provides a method for updating a system message, including: determining a first update indication and a second update indication according to the SIB type to which the system message to be updated belongs, wherein the first update indication is used to indicate whether the first SIB type system message is updated, and the second update indication is used to indicate whether the second SIB type system message is updated; generating and sending a paging message based on the first update indication and the second update indication. Thus, by using a special indication (i.e., the second update indication) in the paging message to clearly indicate whether the second SIB type system message is updated, the processing logic of the UE is optimized, making it possible to save UE power consumption, which is conducive to improving the interaction efficiency between the UE and the network.

[0034] As mentioned in the background art, the existing system message update mechanism has defects, especially when the extended SIB is updated, it will seriously affect the power consumption of the old version UE.

[0035] The inventor of the present application has found through analysis that this is because the existing paging message uses a unique update indication to indicate the update status of the original SIB and the extended SIB. That is, whether the original SIB or the extended SIB is updated, it is indicated by the same indication field in the paging message. This results in the UE being unable to effectively identify whether the update is the original SIB or the extended SIB.

[0036] To solve the above technical problems, an embodiment of the present invention provides a method for updating a system message, including: receiving a paging message; determining a system message to be updated in a first SIB type system message according to a first update indication in the paging message, wherein the first update indication is used to indicate whether the first SIB type system message is updated; determining a system message to be updated in a second SIB type system message according to a second update indication in the paging message, wherein the second update indication is used to indicate whether the second SIB type system message is updated.

[0037] The solution of the present invention can implement the update of system messages in a more targeted manner, and will not affect the old version UE when updating and expanding the SIB, thereby reducing the meaningless power consumption of the old version UE. Specifically, an indication information is added to the paging message specifically for indicating the update status of the second SIB type system message. That is, the update status of the two types of SIB type system messages is indicated separately, so that both the new and old version UEs can perform reasonable update operations according to the corresponding indication information. For example, the first update indication enables both the new and old version UEs to update the first SIB type system message in a timely manner. For another example, the second update indication can prevent the old version UE from performing meaningless system message update operations and wasting power consumption, while ensuring that the new version UE can update the second SIB type system message in a timely manner.

[0038] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] Figure 1 It is a flow chart of a first system message updating method according to an embodiment of the present invention.

[0040] This implementation scheme may be applied to a user equipment side, such as being executed by a UE on the user equipment side.

[0041] Specifically, the UE may include an old version UE or a new version UE. The difference between the old and new version UEs is that the protocol versions that can be recognized are different. For example, the old version UE cannot recognize the information element of the special scheduling extension SIB newly introduced in the protocol. If the new information element is introduced in R12, the old version UE usually includes UEs using R11 and earlier protocol versions.

[0042] Furthermore, the extended SIB may include SIB19 and subsequent SIBs, and each SIB contains a series of system information parameters related to a specific function. For example, SIB19 is about Sidelink discovery. For another example, SIB20 is about Single Cell Point To Multipoint (SC-PTM) service. For another example, SIB21 and SIB26 are about the Internet of Vehicles, that is, the exchange of information from the vehicle to everything (V2X). For another example, SIB24 is about New Radio (NR) cell reselection. For another example, SIB25 is about Unified Access Control (UAC).

[0043] For ease of description, this embodiment refers to the original SIB (ie, SIB1, SIB2-SIB18) as a first SIB type system message, and the extended SIB as a second SIB type system message.

[0044] Further, refer to Figure 1 The method for updating the system message in this embodiment may include the following steps:

[0045] Step S101, receiving a paging message;

[0046] Step S102, determining a system message to be updated in a first SIB type system message according to a first update indication in the paging message, wherein the first update indication is used to indicate whether the first SIB type system message is updated;

[0047] Step S103: determine the system message to be updated in the second SIB type system message according to the second update indication in the paging message, wherein the second update indication is used to indicate whether the second SIB type system message is updated.

[0048] Furthermore, the first SIB type system message may include SIB1 to SIB18, and the second SIB type system message may include an extended SIB.

[0049] The step S102 and step S103 may be executed synchronously or asynchronously. When executed asynchronously, the execution order of the step S102 and step S103 may be interchanged.

[0050] In a specific implementation, if the value of the first update indication is true (True), it indicates that the first SIB type system message is updated; if the value of the first update indication is false (False), it indicates that the first SIB type system message is not updated.

[0051] Similarly, if the value of the second update indication is True, it indicates that the second SIB type system message is updated; if the value of the second update indication is False, it indicates that the second SIB type system message is not updated.

[0052] In a specific implementation, the paging message may include a 2-bit indication field, wherein one bit corresponds to the first update indication, used to indicate the update status of the first SIB type system message (SIB1-SIB18); and the other bit corresponds to the second update indication, used to indicate the update status of the second SIB type system message (extended SIB, i.e., currently including SIB19-SIB26, and may include SIB27 introduced in the future, etc.).

[0053] Therefore, the paging message clearly indicates whether the extended SIB is updated through the second update indication.

[0054] For a new version UE, if the values ​​of the first update indication and the second update indication indicate that both the first SIB type system message and the second SIB system message are updated, it is necessary to receive updates of the original SIB and the extended SIB. Accordingly, the new version UE implementing this implementation scheme determines both the first SIB type system message and the second SIB system message as system messages to be updated.

[0055] For old version UEs, since the second update indication (i.e., the above-mentioned "another bit") is an additional bit, the old version UE can determine whether to perform the update operation only according to the first update indication. That is, the old version UE receives the update of the original SIB only when the first update indication indicates that the first SIB type system message is updated. If the first update indication indicates that the first SIB type system message is not updated, and the second update indication indicates that the second SIB type system message sends an update, the old version UE does not perform the update operation of the system message.

[0056] In a variation, if the first update indication indicates that the first SIB type system message is not updated, and the second update indication indicates that the second SIB type system message is updated, the UE needs to receive an update of the extended SIB. Accordingly, the new version UE implementing this implementation determines the second SIB type system message as a system message to be updated.

[0057] In one variation, if the first update indication indicates that the first SIB type system message is updated, and the second update indication indicates that the second SIB type system message is not updated, the UE only receives the update of the original SIB. Accordingly, the new version UE implementing this implementation determines the first SIB type system message as the system message to be updated.

[0058] In a variation, if the paging message includes only the first update indication, and the UE cannot determine whether the cell sending the paging message can separately indicate the update of the extended SIB through the paging message, then the UE needs to receive the update of the original SIB and the update of the extended SIB. Accordingly, the UE executing this implementation scheme can determine both the first SIB type system message and the second SIB type system message as the system message to be updated.

[0059] For example, the serving cell where the UE currently resides may not support indicating the update of the extended SIB separately through the second update indication. Therefore, when the received paging message includes only a 1-bit update indication, the UE receiving the paging message needs to check whether both the original SIB and the extended SIB are updated.

[0060] In a specific implementation, after step S103, the updating method of this embodiment may further include the steps of: acquiring scheduling information corresponding to the system message to be updated; and receiving the updated system message to be updated based on the scheduling information.

[0061] For example, if it is determined through the paging message that the system message to be updated is a first SIB type system message, the UE may read SIB1, and obtain new content of the first SIB type system message according to the scheduling information of the original SIB in SIB1.

[0062] For another example, if it is determined through the paging message that the system message to be updated is a second SIB type system message, the UE may read SIB1, and obtain new content of the second SIB type system message according to the scheduling information of the extended SIB in SIB1.

[0063] For another example, if it is determined through a paging message that the system message to be updated is a first SIB type system message and a second SIB type system message, the UE can read SIB1 and obtain the new content of the first SIB type system message and the new content of the second SIB type system message based on the scheduling information of the original SIB and the scheduling information of the extended SIB in SIB1.

[0064] In a specific implementation, the obtaining of the scheduling information corresponding to the system message to be updated may include the step of: if there is a demand for the network service associated with the system message to be updated, obtaining the scheduling information corresponding to the system message to be updated.

[0065] Specifically, when the UE finds that the extended SIB is updated, if the UE does not support the corresponding function or is not interested in the related service, the UE may not update these system messages.

[0066] That is, in this specific implementation, when the second update indication in the paging message indicates that the extended SIB is updated, the UE may receive the update of the extended SIB only when the UE supports the corresponding function or is interested in the related service.

[0067] From the above, the adoption of this implementation scheme can realize the update of system messages in a more targeted manner, and will not affect the old version UE when updating and expanding the SIB, thereby reducing the meaningless power consumption of the old version UE. Specifically, an indication information is added to the paging message specifically for indicating the update status of the second SIB type system message. That is, the update status of the two types of SIB types of system messages is indicated separately, so that both the new and old version UEs can perform reasonable update operations according to the corresponding indication information. For example, the first update indication enables both the new and old version UEs to update the first SIB type system message in a timely manner. For another example, the second update indication can prevent the old version UE from performing meaningless system message update operations and wasting power consumption, while ensuring that the new version UE can update the second SIB type system message in a timely manner.

[0068] Taking the new version UE as an example, the system message to be updated in the first SIB type system message is determined according to the first update indication, and the system message to be updated in the second SIB type system message is determined according to the second update indication. Thus, the new version UE can clearly know whether the original SIB and the extended SIB are updated.

[0069] Taking an old version UE as an example, if the first update indication determines that the first SIB type system message has not been updated, and the second update indication determines that the second SIB type system message has been updated, the old version UE can confirm that it does not need to perform an update operation, thereby making it possible to save meaningless power consumption of the UE.

[0070] Typically, the transmission of the paging message includes downlink control signaling indicating paging and a paging message (such as an RRC message) indicated by the downlink control signaling. In a specific implementation, the first update indication and the second update indication may both be located in the paging message.

[0071] In a variation, the second update indication may be indicated by a spare bit in the downlink control signaling indicating the paging message, so as to avoid affecting the size of the paging message.

[0072] For the old version UE, no special processing is performed on the spare bits in the downlink control signaling related to the paging message, so no unnecessary update operation is performed due to the second update indication.

[0073] For a new version UE, whether the extended SIB is updated can be known from the downlink control signaling indicating the paging message, and the updated extended SIB can be received more quickly.

[0074] Figure 2 2 is a schematic diagram of the structure of the first system message updating device according to an embodiment of the present invention. Those skilled in the art will appreciate that the system message updating device 2 described in this embodiment can be used to implement the above Figure 1 The method and technical solution described in the embodiments.

[0075] Specifically, refer to Figure 2 The system message updating device 2 described in this embodiment may include: a receiving module 21, used to receive a paging message; a first determination module 22, used to determine the system message to be updated in the first SIB type system message according to the first update indication in the paging message, wherein the first update indication is used to indicate whether the first SIB type system message is updated; a second determination module 23, used to determine the system message to be updated in the second SIB type system message according to the second update indication in the paging message, wherein the second update indication is used to indicate whether the second SIB type system message is updated.

[0076] For more information about the working principle and working method of the system message updating device 2, please refer to the above Figure 1 The relevant description in will not be repeated here.

[0077] Figure 3 It is a flowchart of a second method for updating system messages according to an embodiment of the present invention.

[0078] This implementation scheme may be applied to the network side, such as being executed by a base station on the network side.

[0079] Specifically, refer to Figure 3 The method for updating the system message in this embodiment may include the following steps:

[0080] Step S301, determining a first update indication and a second update indication according to the SIB type to which the system message to be updated belongs, wherein the first update indication is used to indicate whether a system message of a first SIB type is updated, and the second update indication is used to indicate whether a system message of a second SIB type is updated;

[0081] Step S302: Generate and send a paging message based on the first update indication and the second update indication.

[0082] Those skilled in the art will appreciate that the steps S301 and S302 can be considered as the same as the above steps. Figure 1 The steps S101 to S103 in the embodiment shown are corresponding execution steps, and the two complement each other in terms of specific implementation principles and logic. Figure 1 The relevant description of the illustrated embodiment will not be repeated here.

[0083] Furthermore, the first SIB type system message may include SIB1 to SIB18, and the second SIB type system message may include an extended SIB.

[0084] In a specific implementation, the cell may determine specific values ​​of the first update indication and the second update indication according to the update status of the system message, and then generate and broadcast the paging message.

[0085] For example, when the first SIB type system message is updated, the value of the first update indication is set to True; otherwise, it is set to False.

[0086] For another example, when the second SIB type system message is updated, the value of the second update indication is set to True; otherwise, it is set to False.

[0087] In a specific implementation, the first update indication and the second update indication may be located adjacently in the paging message, or one or more fields may be spaced between them.

[0088] From the above, by using a special indication (ie, the second update indication) in the paging message to clearly indicate whether the second SIB type system message is updated, the UE processing logic is optimized, making it possible to save UE power consumption, which is beneficial to improving the interaction efficiency between the UE and the network.

[0089] Figure 4 4 is a schematic diagram of the structure of the second system message updating device according to an embodiment of the present invention. Those skilled in the art will appreciate that the system message updating device 4 described in this embodiment can be used to implement the above Figure 3 The method and technical solution described in the embodiments.

[0090] Specifically, refer to Figure 4 The system message updating device 4 described in this embodiment may include: a determination module 41, used to determine a first update indication and a second update indication according to the SIB type to which the system message to be updated belongs, wherein the first update indication is used to indicate whether a first SIB type system message is updated, and the second update indication is used to indicate whether a second SIB type system message is updated; a sending module 42, used to generate and send a paging message based on the first update indication and the second update indication.

[0091] For more information about the working principle and working method of the system message updating device 4, please refer to the above Figure 3 The relevant description in will not be repeated here.

[0092] In a typical application scenario, an old version UE (such as a UE supporting protocol version 10 (Release 10, referred to as R10)) and a new version UE (such as a UE supporting protocol version 15 (Release 15, referred to as R15)) reside in a Long Term Evolution (LTE) serving cell.

[0093] Assume that the serving cell broadcasts SIB1, SIB2, SIB3, SIB5 and SIB24. The scheduling of SIB2 to SIB5 uses the scheduling information of the existing system message, and SIB24 uses the newly introduced extended SI scheduling (SchedulingInfoExt) as its scheduling information.

[0094] For an old version UE, after reading MIB and SIB1, SIB2 to SIB5 can be read through the scheduling information of the existing system information.

[0095] For the new version UE, after reading MIB and SIB1, SIB2 to SIB5 can be read through the scheduling information of the existing system information, and SIB24 can be read through the scheduling of the extended SI (SchedulingInfoExt).

[0096] For UEs that support NR independent deployment, it is necessary to read SIB24. For UEs that do not support NR independent deployment, it is not necessary to read SIB24.

[0097] At a certain moment, the serving cell decides to update SIB24. In order to avoid affecting the old version UE, the paging message can be enhanced, that is, based on the original first update indication (systemInfoModification), an independent indication extended SIB update information element (such as the second update indication systemInfoModificationExt) is introduced.

[0098] Specifically, the field description of the second update indication in the paging message may be: systemInfoModificationExt ENUMERATED{true}OPTIONAL, wherein ENUMERATED means enumeration and OPTIONAL means optional.

[0099] The second update indication may be used to indicate the update of the extended SIB (ie, the system message after SIB19).

[0100] In this application scenario, since only SIB24 is updated, the serving cell may set the first update indication (systemInfoModification) to False in the paging message; and set the second update indication (systemInfoModificationExt) to True.

[0101] For old version UEs, after receiving the paging message, if they find that they do not have their own UE identification (ID) and no indication of system message update (because the value of the first update indication is False), these old version UEs can continue to maintain the current state without receiving SIB1, etc. Therefore, based on the system message update mechanism described in this embodiment, old version UEs can effectively save power consumption.

[0102] For the new version UE, if the second update indication (systemInfoModificationExt) is found to be True through the paging message, the new version UE is aware that the extended SIB has been updated. Therefore, the new version UE can read SIB1 and obtain the new content of SIB24 according to the scheduling information of the extended SIB such as SIB24 in SIB1. Therefore, based on the update mechanism of the system message described in this embodiment, the new version UE can be more targeted to know the updated system message block.

[0103] After a period of time, if the serving cell needs to update SIB2 and SIB24 at the same time, the serving cell indicates through a paging message that the first update indication (systemInfoModification) is True and sets the second update indication (systemInfoModificationExt) to True as well.

[0104] At this time, for the new version UE, the new version UE needs to receive updates of SIB1 to SIB18 and updates of extended SIBs.

[0105] For the old version UE, the old version UE only needs to receive updates of SIB1 to SIB18.

[0106] Furthermore, based on the update mechanism of the system message described in this embodiment, the new version UE can be aware of whether the extended SIB is updated through the second update indication. When the extended SIB is updated, the new version UE can decide whether to receive the corresponding extended SIB according to its actual state.

[0107] For example, for the update of SIB24, the new version UE needs to receive the update of SIB24 only when it supports NR standalone deployment. When the new version UE does not support NR standalone deployment, even if the new version UE receives a paging message indicating the update of the second SIB type, the new version UE does not need to receive the update of SIB24.

[0108] For another example, for the update of SIB20, the update of SIB20 needs to be received only when the new version UE is interested in SC-PTM.
