Background

In a mobile communication network of the fifth generation mobile communication technology (5th generation mobile networks, 5G), since the paging channel radio resource physical parameters of each cell are included in the system Information Block (systemlnformationblock Type1, SIB1) broadcasted by the cell, and the radio resource location of the SIB1 is stored in the Master Information Block (MIB) broadcasted by the cell, in order to monitor the paging channel of the camped cell, a User Equipment (UE) needs to acquire MIB Information and SIB1 Information of the cell, and can start monitoring the paging channel of the cell after the cell camping and parameter configuration of the corresponding physical layer are completed.

Currently, in the related art, when paging channel monitoring is implemented, two ways, namely, a current system information active acquisition mechanism and a historical system information direct multiplexing mechanism, are mainly used to implement the acquisition of MIB information and SIB1 information by the UE, and cell residence and parameter configuration of a corresponding physical layer are completed according to the MIB information and SIB1 information, thereby implementing the monitoring of the paging channel of the cell. However, an optimized space exists in a manner of actively acquiring current system information by the UE, and meanwhile, the accuracy of the system information cannot be guaranteed by a manner of directly multiplexing historical system information, which results in a decrease in the success rate of the UE in a subsequent access process. Therefore, how to efficiently monitor the paging channel becomes an urgent problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

According to the 3rd Generation Partnership Project (3 GPP) protocol, the SIB1 information broadcasted by the cell mainly contains various parameters required for UE camping and the broadcast status of other system message blocks. Table 1 shows a plurality of Information Elements (IEs) included in the SIB1 information and their corresponding roles for each information element.

It can be seen that the various Information contained in the SIB1 Information in table 1 includes, in addition to the Information necessary for camping in the cell, such as the cell Access related Information cellaccesratedsedlnfo and controlestifatfailure Control, serving cell configuration parameter Information servingCellConfigCommon used for listening to various downlink channels and initiating uplink Access in the cell, and cell selection criterion configuration Information cellselecteationinfo, Other System Information (OSI), i.e., Information si-SchedulingInfo used for acquiring broadcast states of SIBs 2 to SIB9, and various timer Information unification of the Radio Resource Control (RRC) layer UAC-BarringInfo and infinite Resource Control (RRC) layer, and so on. One part of the information may be considered as information necessary for cell camping, that is, after receiving and analyzing the SIB1 information, a Radio Resource Control (RRC) layer needs to configure the information to a Media Access Control (MAC) layer and a physical layer of the UE, and the other part is some parameter information used by the RRC layer itself.

TABLE 1

It is understood that the parameters carried in SIB1 are not fixed and the probability of each parameter changing is not the same. Such as: since the 5G network cell can dynamically control the broadcast status of other system messages except MIB and SIB1, the possibility of parameter change of the information si-scheduling info required for acquiring the broadcast status of SIB2-SIB9 is relatively high, and the possibility of parameter change of the information cell selection info and cell access relationship info required for the cell to dynamically adjust the number of UEs camping on the cell is relatively moderate. Further, since the change of the uplink and downlink infinite resource configuration parameters servingCellConfigCommon of the serving cell required for listening the downlink channel and initiating the uplink access in the cell directly results in the random access failure or the loss of service coverage of the UE residing in the cell, all UEs currently residing in the cell should re-perform the cell selection procedure to re-reside in the cell, and therefore, the possibility of the change of the servingCellConfigCommon parameter is relatively small, and the change probability is very small.

In a 5G mobile communication network, after a cell camping process is completed, a UE can monitor paging on a paging channel of the cell, or initiate an uplink service connection request on an uplink common channel. Since the physical parameters of the paging channel radio resources of each cell are contained in the system information block SIB1 broadcasted by the cell, and the radio resource location of the SIB1 is stored in the main system information block MIB broadcasted by the cell, in order to monitor the paging channel of the camped cell, the UE needs to acquire MIB information and SIB1 information of the cell, and can start to monitor the paging channel of the cell after the cell camping and the parameter configuration of the corresponding physical layer are completed.

Currently, in the related art, when paging channel monitoring is implemented, two ways, namely, a current system information active acquisition mechanism and a historical system information direct multiplexing mechanism, are mainly used to implement the acquisition of MIB information and SIB1 information by the UE, and cell residence and parameter configuration of a corresponding physical layer are completed according to the MIB information and SIB1 information, thereby implementing the monitoring of the paging channel of the cell.

Specifically, in the conventional paging channel monitoring mode of the current system information active acquisition mechanism, when the UE reselects or switches to a new cell due to user movement or change of cell signal quality, the MIB information and SIB1 information of the cell are acquired first, and the paging channel of the cell can be monitored only after the cell completes parameter configuration of a corresponding physical layer. However, on the basis of the current active system information acquisition mechanism, if the UE has camped in the cell previously, i.e. has read the SIB1 information of the cell, the UE acquires the MIB information and the SIB1 information each time the UE camps in the cell, which causes the terminal to work repeatedly and there is an optimization space.

Further, in order to reduce the defect that the UE repeatedly reads the system information after camping, an improved paging channel monitoring mode of a historical system information direct multiplexing mechanism is proposed in the related art, when reselecting or switching to a new cell each time, if the new cell is a cell in which the UE has previously camped and stored system information, the UE only reads MIB information, and when confirming that the read MIB information is the same as the stored MIB information, the reading process of acquiring SIB1 information is skipped, and parameter configuration is directly performed by using SIB1 information of the cell stored inside the UE, so as to save the time for reading SIB1, thereby advancing the starting time for the UE to monitor a cell paging channel. However, although the time for monitoring the paging channel is advanced in the improved method of directly multiplexing the historical system information compared with the current method of actively acquiring the system information, since the system information of the cell is not fixed, if the system information of the cell changes during the period that the UE leaves the cell, when the UE reselects or switches back to the cell, the parameter configuration is performed by directly using the SIB1 information stored in the history, which may result in that the UE cannot read other system messages SIB2-SIB9, or risk exists in a subsequent access process of camping, and considerable limitations are brought to activities of the UE after camping.

Therefore, an efficient paging channel monitoring method is urgently needed, which can optimize the original monitoring method of actively acquiring the current system information, and can solve the problem that the success rate of subsequent access of the UE residing in the system is reduced due to the fact that the accuracy of the system information cannot be guaranteed in the historical system information direct multiplexing mechanism.

In order to solve the problems in the existing paging channel monitoring process, the embodiments of the present application provide a paging channel monitoring method and apparatus, a terminal, a chip and a storage medium, and in particular, a terminal may not only perform reselection or handover to a target cell in which historical SIB1 information is already stored, the resource configuration information is directly determined according to the historical SIB1 information, so as to advance the initial monitoring time of the target cell paging channel, but also can renew the resource configuration information determined according to the historical SIB1 information according to the current SIB1 information when the current SIB1 information of the target cell changes, therefore, the paging channel of the target cell is monitored continuously through the updated resource allocation information, and therefore, the method not only advances the initial time for monitoring the paging channel of the target cell, meanwhile, the accuracy of system information can be effectively ensured, and the efficient monitoring of the paging channel is further realized.

It should be understood that the technical solution of the embodiment of the present invention may be applied to a fifth Generation mobile communication technology (5th Generation mobile networks or 5th Generation wireless systems, 5th-Generation, 5G) system.

It should be understood that in the 5G new air interface technology, the radio interface is an interface between the terminal and the access network, and communication between the UE and the access network needs to comply with the received specification. Specifically, the PHY is located at the bottom layer of the radio interface, provides all functions required for bit stream transmission in a physical medium, and is mainly used for providing information transmission services for the MAC layer and the upper layer. The Data Link layer mainly comprises 4 sublayers of MAC, Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP) and Service Data Adjustment Protocol (SDAP), wherein the SDAP sublayer is positioned on a user plane, the other 3 sublayers are positioned on the user plane and a Control plane at the same time, and the Data Link layer is positioned between a physical layer and a network layer and can provide services for the network layer on the basis of the services provided by the physical layer; the network layer is an RRC layer, located in the control plane of the access network, and is responsible for completing all signaling processing of interaction between the access network and the terminal. Exemplarily, fig. 1 is a schematic diagram of a radio protocol architecture of a terminal UE side and an access network gNB side, and as shown in fig. 1, the radio protocol architecture for the terminal UE side and the access network gNB side includes three layers and two surfaces, where the three layers are a physical layer, a data link layer and a network layer, and the two surfaces include a control surface and a user surface, and in a 5G protocol stack, the control surface includes a physical layer, a MAC layer, an RLC layer, a PDCP layer and an RRC layer; besides the user plane comprises a physical layer, an MAC layer, an RLC layer and a PDCP layer which are the same as the control plane, an SDAP layer is added to the user plane in the 5G protocol architecture, and therefore the SDAP layer is only used for the user plane, and the control plane protocol stack does not comprise the SDAP layer. Specifically, in the wireless protocol architecture: (1) the physical layer provides a transport channel to the MAC layer; (2) the MAC layer provides a logical channel to the RLC layer; (3) the RLC layer provides the PDCP layer with an RLC channel; (4) the PDCP layer provides an infinite bearer to the SDAP layer or the RRC layer; (5) the RRC layer is a network upper layer, and is mainly responsible for acquiring radio resources (i.e., radio bearers provided by the PDCP layer), and for configuring lower layers below RRC using RRC signaling between the UE side of the terminal and the gNB side of the access network.

It should be noted that, in the embodiment of the present application, the process of the UE performing the paging channel monitoring method mainly involves a physical layer, a MAC layer in a data link layer, and an RRC layer. Specifically, in the process that the UE performs monitoring of the paging channel of the target cell, the UE needs to complete cell synchronization and PBCH blind detection first to obtain MIB information, then performs analysis processing on the MIB information through the RRC layer to determine location parameters, further obtains SIB1 information according to the location parameters, continues to perform analysis processing on SIB1 information through the RRC layer, obtains resource configuration information, and performs parameter configuration processing on the MAC layer and the physical layer of the UE side according to the resource configuration information, thereby enabling the UE to monitor paging on the paging channel corresponding to the target cell.

It should be understood that in the embodiment of the present application, the paging channel monitoring apparatus 10 may refer to an access terminal device, UE, subscriber unit, subscriber station, Mobile station, remote terminal device, Mobile device, user terminal device, Wireless communication device, user agent or user equipment, and the terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G Network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like. In the following embodiments, the paging channel monitoring apparatuses are all described using UEs.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

An embodiment of the present application provides a paging channel monitoring method, and fig. 2 is a schematic diagram illustrating an implementation flow of the paging channel monitoring method provided in the embodiment of the present application, as shown in fig. 2, in the embodiment of the present application, a method for UE to perform paging channel monitoring may include the following steps:

step 101, when reselecting or switching to the target cell, judging whether the historical SIB1 information of the target cell is stored.

In the embodiment of the present application, when the UE reselects or switches to a target cell, the UE first needs to determine whether historical SIB1 information corresponding to the target cell is stored locally.

It should be noted that, in the embodiment of the present application, when a user moves or the channel quality of a cell changes, the UE may need to perform cell search, select a new cell, and complete the procedures of camping, monitoring a paging channel, initiating random access, and the like on the new cell.

Optionally, when the UE is in an RRC idle state, if the user moves or the channel quality of the cell changes, the UE may initiate cell search and reselect to the new cell; alternatively, if the user moves or the cell channel quality changes while the UE is in the RRC connected state, the UE may switch to the new cell. It is to be understood that, in the embodiment of the present application, the new cell is the target cell.

Specifically, in order for the UE to successfully camp on the target cell and monitor paging on the paging channel of the target cell, the UE first needs to perform cell synchronization, and after completing frequency sweep and target cell synchronization, continue to acquire system information of the cell, including MIB information and SIB1 information, and then perform cell camping through configuration parameters carried in the system information of the cell, so as to monitor the paging channel of the target cell. Here, since MIB information and SIB1 information are always periodically broadcasted in the whole cell range, the UE can acquire system information at any time.

It should be noted that, in the embodiment of the present application, in order to accelerate the residence time in the target cell and monitor the paging channel of the target cell earlier, when the UE reselects or switches to the target cell, the UE may determine whether historical SIB1 information corresponding to the target cell is locally stored. That is, it is determined whether the UE has camped on the target cell historically and has stored the historical SIB1 information corresponding to the target cell, or whether the UE has not camped on the target cell and has acquired and stored the historical SIB1 information corresponding to the target cell by another method.

Optionally, the historical SIB1 information of the target cell may be historical SIB1 information of the target cell stored after the UE previously camped on the target cell through reselection or handover.

Optionally, the historical SIB1 information of the target Cell may also be historical SIB1 information of the target Cell, which is acquired and stored in a process of performing Cell Global Identity (CGI) reporting when the UE is in an RRC connected state with another Cell. Specifically, when the UE establishes RRC connection with another cell and executes a CGI reporting process, the UE may receive a measurement configuration instruction sent by the other cell, read historical SIB1 information of the target cell according to the measurement configuration instruction, and store the information.

It should be noted that, in the embodiment of the present application, the target cell supports the 5G network communication technology.

Specifically, in the embodiment of the present application, the UE may obtain current identification information corresponding to the target Cell, such as a Physical Cell Identity (PCI), and current transmission resource parameters, such as frequency point and frequency band information, corresponding to the target Cell by performing frequency sweeping and target Cell synchronization, and further determine whether historical SIB1 information of the target Cell is locally stored according to the current identification information and the current transmission resource parameters corresponding to the target Cell.

Optionally, in an embodiment of the present application, the UE may locally read the historical identification information and the historical transmission resource parameter corresponding to the candidate cell, and determine whether to locally store the historical SIB1 information corresponding to the target cell by combining the historical identification information and the historical transmission resource parameter corresponding to the candidate cell, and the current identification information and the current transmission resource parameter corresponding to the target cell. The candidate cell is a cell corresponding to SIB1 information that is historically stored locally by the UE. It is understood that the UE may store multiple historical SIB1 information for multiple alternative cells.

It can be understood that, in the embodiment of the present application, if the UE determines that the historical identification information and the historical transmission resource parameter corresponding to the candidate cell are identical to the current identification information and the current transmission resource parameter corresponding to the target cell, it may be determined that the UE locally stores the historical SIB1 information of the target cell. That is, the UE has historically camped on the target cell and stored the historical SIB1 information of the target cell, or the UE has not camped on the target cell but acquired and stored the historical SIB1 information corresponding to the target cell through the CGI reporting process.

It is understood that, in the embodiment of the present application, if the UE determines that the historical identification information and the historical transmission resource parameter corresponding to the candidate cell and the current identification information and the current transmission resource parameter corresponding to the target cell are not the same, it may be determined that the historical SIB1 information of the target cell is not stored locally by the UE. That is, the UE does not historically camp on the target cell, or the UE does not acquire the historical SIB1 information corresponding to the target cell through the CGI reporting process even when the UE historically camps on another cell.

Further, in the embodiment of the present application, after the UE determines whether the historical SIB1 information corresponding to the target cell is stored locally when reselecting or switching to the target cell, the UE may further determine that the historical SIB1 information corresponding to the target cell is stored in the UE, or that the historical SIB1 information corresponding to the target cell is not stored in the UE.

And 102, if the information of the historical SIB1 is determined to be stored, determining resource configuration information according to the information of the historical SIB1, and monitoring a paging channel of the target cell through the resource configuration information.

In the embodiment of the present application, after the UE determines whether the historical SIB1 information corresponding to the target cell is stored or not when reselecting or switching to the target cell, if it is determined that the historical SIB1 information corresponding to the target cell is stored in the UE, the UE may directly determine the resource configuration information according to the historical SIB1 information, and monitor the paging channel of the target cell through the resource configuration information, that is, monitor the paging channel of the target cell earlier.

It should be noted that, in the embodiment of the present application, if the UE determines that the historical SIB1 information corresponding to the target cell is stored locally, that is, it is determined that the UE has historically resided in the target cell, or the UE has not resided but acquired the historical SIB1 information corresponding to the target cell through the CGI reporting process, the UE skips the reading process of the SIB1 information, directly uses the locally stored historical SIB1 information to determine resource configuration information, and monitors the paging channel of the target cell through the resource configuration information, so that the starting time of monitoring the paging channel of the target cell is advanced.

Specifically, in the embodiment of the present application, when the UE determines resource configuration information according to locally stored historical SIB1 information and monitors a paging channel of a target cell through the resource configuration information, the UE may analyze the historical SIB1 information through an RRC layer to obtain first resource configuration information, and then the RRC layer performs parameter configuration processing on an MAC layer and a physical layer of the UE side according to the first resource configuration information, thereby enabling the UE to monitor paging on the paging channel corresponding to the target cell.

More specifically, since the UE needs to monitor paging on the paging channel of the cell after completing the cell camping process, the UE may first successfully camp on the target cell according to the cell selection criterion configuration information cellselecteationinfo in the first resource configuration information, and then perform parameter configuration on the MAC layer and the physical layer according to the uplink and downlink infinite resource configuration parameter servingCellConfigCommon, so that the UE can monitor the paging channel and initiate an access request in the target cell.

That is, when the UE stores the historical SIB1 information of the target cell, the UE saves the time for reading the SIB1 information, and performs the parameter configuration process directly according to the historical SIB1 information, thereby speeding up the time that the UE camps on the target cell and also advancing the starting time of monitoring paging on the paging channel of the target cell.

Further, in the embodiment of the present application, after determining that the historical SIB1 information is stored, determining the resource configuration information according to the historical SIB1 information, and monitoring the paging channel of the target cell through the resource configuration information, if the SIB1 information of the target cell is changed, the UE needs to update the resource configuration information to monitor the paging channel of the target cell through the updated resource configuration information.

And 103, acquiring the current SIB1 information of the target cell.

In an embodiment of the present application, when the UE reselects or switches to a target cell, the UE may acquire current SIB1 information of the target cell.

It should be noted that, in the embodiment of the present application, after performing frequency sweeping and cell synchronization by the UE and acquiring the current identification information and the current transmission resource parameter corresponding to the target cell, the UE may determine whether the historical SIB1 information of the target cell is locally stored, and simultaneously read the current SIB1 information of the target cell in parallel, that is, the UE may perform the determination process of the historical SIB1 information and acquire the current SIB1 information corresponding to the target cell, where the two execution processes are performed in synchronization with each other and do not affect each other. It can be seen that, in the embodiment of the present application, step 101 and step 103 may be a parallel synchronization mechanism.

Specifically, in the embodiment of the present application, after completing cell synchronization, the UE may perform PBCH blind detection, read MIB information, perform analysis processing on the MIB information through an RRC layer, determine a location parameter, and then receive SIB1 information sent by a target cell according to the location parameter.

Further, in the embodiment of the present application, after acquiring the current SIB1 information of the target cell, the UE may update the resource configuration information according to the current SIB1 information when determining that the SIB1 information of the target cell changes.

And step 104, when the historical SIB1 information is different from the current SIB1 information, updating the resource configuration information according to the current SIB1 information to obtain updated resource configuration information, and monitoring a paging channel of the target cell through the updated resource configuration information.

In the embodiment of the application, the UE determines the resource configuration information according to the historical SIB1 information and monitors the paging channel of the target cell through the resource configuration information; after acquiring the current SIB1 information of the target cell, and after

steps

102 and 103, if the SIB1 information of the target cell is changed, that is, the acquired current SIB1 information is not the same as the historical SIB1 information, the UE needs to update the resource configuration information according to the current SIB1 information again to obtain updated resource configuration information, so that the UE continues to monitor the paging channel of the target cell through the updated resource configuration information.

It should be noted that, in the embodiment of the present application, if the SIB1 information corresponding to the target cell changes, the historical SIB1 information stored when the UE historically camps on the target cell, or the historical SIB1 information acquired through the CGI reporting process may not be the current SIB1 information of the target cell.

Specifically, since the target cell can dynamically adjust the number of UEs camping on the cell or adjust the broadcast status of other system information besides SIB1 information by adjusting the configuration parameters carried in SIB1 information, the system information of the target cell may change during the course that the historical UE leaves the target cell, so that when the UE reselects or switches to the target cell again, the historical SIB1 information of the target cell stored by the UE will no longer be the current SIB1 information of the target cell.

Further, if the historical SIB1 information stored in the UE is no longer the current SIB1 information, the UE performs resource configuration processing according to the first resource configuration information obtained from the historical SIB1 information, which may cause that the subsequent UEs cannot read system information other than the SIB1 information, or there is a failure risk in the access process initiated by the UE, at this time, the UE needs to perform update processing on the resource configuration information again according to the current SIB1 information corresponding to the target cell to obtain updated resource configuration information, and continues to monitor the paging channel of the target cell according to the updated resource configuration information.

Specifically, when the UE updates the resource configuration information according to the current SIB1 information to obtain updated resource configuration information, and monitors the paging channel of the target cell through the updated resource configuration information, the UE may analyze the current SIB1 information through the RRC layer to obtain second resource configuration information, that is, the updated resource configuration information, and then the RRC layer performs parameter configuration processing again on the MAC layer and the physical layer of the UE side according to the second resource configuration information, so that the UE continues to monitor paging on the paging channel corresponding to the target cell.

It can be seen that, in the embodiment of the present application, on one hand, when the UE reselects or switches to the target cell storing the historical SIB1 information, the UE may directly use the historical SIB1 information to perform resource configuration processing, that is, the RRC layer may configure the infinite resource parameter in the SIB1 information to the MAC layer and the physical layer in advance, so that the UE monitors on the paging channel of the target cell earlier; on the other hand, when the SIB1 information of the target cell changes, that is, the current SIB1 information is different from the locally stored historical SIB1 information, the UE may perform resource configuration processing again according to the current SIB1 information, which not only advances the channel monitoring time, but also ensures the accuracy of system information, and improves the success rate of the subsequent UE initiating the access process.

The embodiment of the application provides a paging channel monitoring method, when a terminal reselects or switches to a target cell, whether historical system information block SIB1 information of the target cell is stored is judged; if the historical SIB1 information is judged to be stored, determining resource configuration information according to the historical SIB1 information, and monitoring a paging channel of a target cell through the resource configuration information; acquiring current SIB1 information of a target cell; and when the historical SIB1 information is different from the current SIB1 information, updating the resource configuration information according to the current SIB1 information to obtain updated resource configuration information, and monitoring a paging channel of the target cell through the updated resource configuration information. That is to say, in the embodiment of the present application, when reselecting or switching to a target cell that has stored information of historical SIB1, a terminal may determine resource configuration information directly according to the information of historical SIB1, so as to advance an initial monitoring time of a paging channel of the target cell, and may also update the resource configuration information determined according to the information of historical SIB1 again according to the information of current SIB1 when the information of current SIB1 of the target cell changes, so as to continue monitoring the paging channel of the target cell through the updated resource configuration information.

Based on the foregoing embodiment, in yet another embodiment of the present application, fig. 3 is a schematic diagram of a second implementation flow of a paging channel monitoring method proposed in the embodiment of the present application, and as shown in fig. 3, in the embodiment of the present application, the acquiring, by the UE, the current SIB1 information of the target cell may include the following steps:

and 105, acquiring MIB information of the target cell.

And 106, analyzing the MIB information to obtain the position parameters.

And step 107, receiving the current SIB1 information sent by the target cell according to the location parameter.

In the embodiment of the present application, the UE may first obtain MIB information of the target cell, perform analysis processing on the MIB information to obtain a location parameter, and then receive current SIB1 information sent by the target cell according to the location parameter.

It should be noted that, in the embodiment of the present application, the UE may determine whether the history SIB1 information of the target cell is stored locally, and simultaneously read the current SIB1 information of the target cell in parallel, that is, the UE may perform the determination process of the history SIB1 information and acquire the current SIB1 information corresponding to the target cell, where the two execution processes are performed in synchronization with each other without mutual influence.

It should be noted that, in the embodiment of the present application, when the UE acquires the current SIB1 information of the target cell, since the radio resource location of the SIB1 is stored in the MIB information broadcasted by the cell, that is, the UE needs to know, according to the MIB information, at which resource location the current SIB1 information of the target cell is read, after completing synchronization of the target cell, the UE needs to continue to read the MIB information corresponding to the target cell, and further acquire the SIB1 information based on the MIB information.

Specifically, after completing cell synchronization, the UE performs PBCH blind detection, reads MIB information, and performs analysis processing on the MIB information through an RRC layer to determine a location parameter, and then receives SIB1 information sent by a target cell according to the location parameter.

Further, in the embodiment of the present application, after acquiring the current SIB1 information of the target cell, the UE may compare the acquired current SIB1 information of the target cell with the locally stored historical SIB1 information, and determine whether the system information SIB1 of the target cell changes during the UE leaving period according to the comparison result.

Further, fig. 4 is a schematic flow chart illustrating a third implementation flow of the paging channel monitoring method provided in the embodiment of the present application, as shown in fig. 4, in the embodiment of the present application, after acquiring the current SIB1 information of the target cell, that is, after step 103, the method for the UE to perform paging channel monitoring may further include the following steps:

and 108, when the historical SIB1 information is the same as the current SIB1 information, continuing to monitor the paging channel of the target cell through the resource configuration information.

Specifically, if the comparison result is that the historical SIB1 information is identical to the current SIB1 information, it indicates that the system information of the target cell has not changed during the UE leaving period, and at this time, the UE does not need to perform the update processing of the resource configuration information and can continue to monitor the paging channel of the target cell through the resource configuration information determined according to the historical SIB1 information. Thus, the UE skips reading the SIB1 information, and directly performs resource configuration processing according to the historical SIB1 information, which leads to an advance in the starting time of monitoring on the target cell paging channel by the UE compared with the case that the UE reads the current SIB1 information and then performs resource configuration processing.

The embodiment of the application provides a paging channel monitoring method, wherein UE can perform resource configuration processing according to historical SIB1 information to monitor a paging channel of a target cell, and then judge whether the historical SIB1 information of the target cell is the same as the current SIB1 information, that is, judge whether system information of the target cell changes during the period of departure of the UE, if the SIB information does not change, the UE directly performs resource configuration according to the historical SIB1 information, and the starting time of the target cell paging channel monitoring time is advanced; if the SIB information is changed, the UE can perform resource configuration processing again through the current SIB1 information of the target cell, and the accuracy of the system information is always maintained.

Based on the foregoing embodiment, in yet another embodiment of the present application, fig. 5 is a schematic diagram illustrating an implementation flow of a paging channel monitoring method provided in the embodiment of the present application, as shown in fig. 5, in the embodiment of the present application, after determining whether historical SIB1 information of a target cell is stored when a UE reselects or switches to the target cell, that is, after step 101, the method for the UE to perform paging channel monitoring may further include the following steps:

and step 109, if the historical SIB1 information is determined not to be stored, performing resource configuration processing according to the current SIB1 information to monitor the paging channel of the target cell.

In the embodiment of the present application, if the UE determines that the historical SIB1 information of the target cell has not been saved, the UE needs to perform resource configuration processing according to the current SIB1 information of the target cell.

It should be noted that, in the embodiment of the present application, the execution process of determining whether the historical SIB1 information corresponding to the target cell is stored locally by the UE and the execution process of actively reading the current SIB1 information corresponding to the target cell by the UE are performed synchronously without mutual influence.

Specifically, in the embodiment of the present application, if it is determined that the historical SIB1 information of the target cell is not stored locally, the UE directly determines resource configuration information according to the acquired current SIB1 information of the target cell, that is, second resource configuration information corresponding to the current SIB1 information, and performs resource configuration processing according to the second resource configuration information, thereby implementing monitoring on the paging channel of the target cell.

It can be understood that, if the UE determines that the historical SIB1 information of the target cell is not stored, indicating that the UE has not resided in the cell historically, or has not acquired the historical SIB1 information in any other way, the UE may perform the resource configuration processing directly according to the acquired current SIB1 information of the target cell. Further, the UE may store the current SIB1 information of the target cell for later reselection to the target cell or handover to the target cell, so as to implement early monitoring of the paging channel of the target cell.

Based on the foregoing embodiment, in a further embodiment of the present application, fig. 6 is a schematic flow chart of a fifth implementation process of a paging channel monitoring method provided in the embodiment of the present application, as shown in fig. 6, in the embodiment of the present application, a method for a UE to perform paging channel monitoring may include the following steps:

step 201, when the UE reselects or switches to the target cell, obtaining current identification information and current transmission resource parameters of the target cell.

Specifically, in the embodiment of the present application, when the UE reselects or switches to a target Cell, in order to successfully camp on the target Cell and monitor paging on a paging channel of the target Cell, the UE first needs to perform Cell synchronization, and obtain current identification information corresponding to the target Cell, such as a Physical Cell Identity (PCI), and current transmission resource parameters, such as frequency point and frequency band information, corresponding to the target Cell by performing frequency sweep and target Cell synchronization.

Further, after acquiring the current identification information and the current transmission resource parameter of the target cell, step 202 and step 203 are executed in parallel.

Step 202, judging whether historical SIB1 information of the target cell is stored or not according to the current identification information and the current transmission resource parameter; if yes, go to step 205; otherwise, step 204 is performed.

Optionally, in an embodiment of the present application, the UE may locally read the historical identification information and the historical transmission resource parameter corresponding to the candidate cell, and determine whether the historical SIB1 information corresponding to the target cell is locally stored by combining the historical identification information and the historical transmission resource parameter corresponding to the candidate cell, and the current identification information and the current transmission resource parameter corresponding to the target cell.

If the UE determines that the historical identification information and the historical transmission resource parameter corresponding to the candidate cell are completely the same as the current identification information and the current transmission resource parameter corresponding to the target cell, it may be determined that the UE locally stores the historical SIB1 information of the target cell, and then step 205 is performed;

if the UE determines that the historical identification information and the historical transmission resource parameter corresponding to the candidate cell are different from the current identification information and the current transmission resource parameter corresponding to the target cell, it may be determined that the historical SIB1 information of the target cell is not stored locally by the UE, and then step 204 is performed.

Step 203, acquiring the information of the main system information block MIB of the target cell, and analyzing the MIB information to obtain the location parameters.

Specifically, after completing cell synchronization, the UE performs PBCH blind detection, reads MIB information, and performs analysis processing on the MIB information through an RRC layer to determine a location parameter, and then receives current SIB1 information of a target cell according to the location parameter.

And step 204, determining second resource configuration information according to the current SIB1 information, and monitoring a paging channel of the target cell through the second resource configuration information.

Specifically, if the UE determines that the history SIB1 information of the target cell is not stored, it indicates that the UE has not resided in the cell historically or has not acquired the history SIB1 information in any other way, and the UE may perform the resource configuration processing directly according to the acquired current SIB1 information of the target cell.

Step 205, determining first resource configuration information according to the historical SIB1 information, and monitoring a paging channel of the target cell through the first resource configuration information.

It should be noted that, in the embodiment of the present application, if the UE determines that the historical SIB1 information corresponding to the target cell is locally stored, the UE skips the reading process of the SIB1 information, and directly uses the locally stored historical SIB1 information to perform resource configuration processing, so that the starting time of monitoring the paging channel of the target cell is advanced.

Specifically, in the embodiment of the present application, when the UE performs resource configuration processing according to locally stored historical SIB1 information, the UE may perform analysis processing on the historical SIB1 information through the RRC layer to obtain first resource configuration information, and then the RRC layer performs parameter configuration processing on the MAC layer and the physical layer of the UE side according to the first resource configuration information, thereby enabling the UE to monitor paging on a paging channel corresponding to a target cell.

Step 206, judging whether the current SIB1 information is the same as the historical SIB1 information; if yes, go to step 207; otherwise, step 208 is performed.

Specifically, since the system information of the target cell may change during the course of the UE leaving the target cell, when the UE reselects or switches to the target cell again, the historical SIB1 information of the target cell stored by the UE will no longer be the current SIB1 information of the target cell. Therefore, the UE can compare the acquired current SIB1 information of the target cell with the locally stored historical SIB1 information, and determine whether the system information SIB1 of the target cell changes during the UE leaving period according to the comparison result.

If the comparison result is that the historical SIB1 information is not the same as the current SIB1 information, indicating that the system information of the target cell is changed during the UE leaving period, jumping to perform step 208; if the comparison result is that the historical SIB1 information is identical to the current SIB1 information, it indicates that the system information of the target cell has not changed during the UE leaving period, and step 207 is performed.

Step 207, continue to monitor the paging channel of the target cell through the first resource configuration information.

And step 208, determining second resource configuration information according to the current SIB1 information, and monitoring a paging channel of the target cell through the second resource configuration information.

If the system information of the target cell changes, at this time, in order to avoid failure of initiating the access process by residing the subsequent UE, the UE needs to update the first resource configuration information according to the current SIB1 information to obtain updated resource configuration information, i.e., the second resource configuration information, and perform resource configuration processing again according to the updated resource configuration information, so that the UE continues to monitor the paging message on the paging channel of the target cell, thereby further ensuring that the residing subsequent UE can acquire other system information except SIB1, and improving the success rate of the UE access process.

Further, fig. 7 is a schematic diagram of a starting time when the UE monitors paging on a paging channel according to the embodiment of the present application, as shown in fig. 7, in a current system information active acquisition mechanism in the related art, when the UE reselects or switches to any cell, the UE needs to perform a reading process of current system information SIB1, and analyze the current SIB1 information through an RRC layer to obtain a configuration parameter, and further configure a physical layer according to the configuration parameter to monitor the paging channel of a target cell; on the other hand, in the historical system information direct multiplexing mechanism in the related art, since the UE stores the historical SIB1 information, when reselecting or switching to the target cell, the UE directly skips the reading process of the current SIB1 information, and directly performs configuration processing on the physical layer according to the locally stored historical SIB1 information, thereby advancing the monitoring time of the UE on the paging channel of the target cell. However, in the paging channel monitoring method provided in the embodiment of the present application, the UE employs a mechanism of reading SIB1 information in parallel and reconfiguring subsequent infinite resources, so that after the UE performs parameter configuration on the MAC layer and the physical layer according to the historical SIB1 information, when the historical SIB1 information is different from the current SIB1 information, the UE may reconfigure the MAC layer and the physical layer according to the current SIB1 information, and there is no need to worry about a failure risk in a subsequent access procedure due to skipping the reading procedure of SIB1, thereby always ensuring the accuracy of system information.

Based on the above-mentioned paging channel monitoring method proposed in steps 201 to 208, the UE can determine whether the history SIB1 information of the target cell is stored locally, and simultaneously read the current SIB1 information of the target cell in parallel, on one hand, when determining that the history SIB1 information is not stored, the UE can directly perform resource configuration processing according to the current SIB1 information, and does not need to perform the reading process of the current SIB information after determining that the history SIB1 information of the target cell is not stored. On the other hand, when the UE judges that the historical SIB1 information is stored, the UE can directly perform resource configuration processing according to the historical SIB1 information so as to advance the paging channel monitoring time. Furthermore, when the UE judges that the current SIB1 information is different from the historical SIB1 information, the UE can perform resource configuration processing again according to the current SIB1 information, so that the accuracy of the system information is always ensured.

It can be seen that, in the embodiment of the present application, compared with the conventional active acquisition mechanism of current system information and the direct multiplexing mechanism of historical system information, the paging channel monitoring method proposed in the present application does not delay the starting time of UE monitoring the paging channel of the target cell when the historical SIB1 information is not stored, and advances the starting time of monitoring the paging channel when the historical SIB1 information is stored, and even when the system information of the target cell changes, the parameter configuration processing can be re-executed according to the current SIB1 information, thereby always ensuring the accuracy of the system information, and further improving the success rate of the subsequent UE being camped to initiate the access process.

In the embodiment of the application, when reselecting or switching to a target cell which stores historical SIB1 information, a terminal can directly perform resource configuration processing according to the historical SIB1 information to monitor the time of a paging channel in advance, and can also update resource configuration information according to the current SIB1 information of the target cell again when the target cell SIB1 information changes, so as to perform resource configuration processing again, thereby continuously monitoring the paging channel of the target cell. The method for monitoring the paging channel can advance the initial time of channel monitoring, has important significance for the UE user to timely acquire earthquake, tsunami and other early warning information broadcasted by the wireless network through the paging channel, and can enable the user to have more time to escape from a dangerous situation.
