Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the method, the terminal and the base station for acquiring system information of the present invention are described in further detail below with reference to the accompanying drawings and embodiments.
Example 1:
the embodiment provides a method for acquiring system information, which is applied to a terminal, for example, an electronic device such as a mobile phone, a vehicle-mounted computer, and a smart watch. To better illustrate the method, the present embodiment adopts a method for acquiring 5G system information for example, but the method is not only applicable to 5G, but also applicable to acquiring system information in LTE system, where information such as transmission mode and priority of each system information is determined according to the function of 5G system information, and the specific scheduling parameters to be involved in the method are described as follows:
as shown in table 1, the table is a case table of 5G system information (MIB, SIB 1-SIB 9), which includes information such as function description of each information, transmission mode, and transmission priority.
TABLE 1
In table 1, the transmission mode includes periodic broadcast transmission (period), timed transmission according to actual demand (on demand), and unicast transmission according to demand (unicast), where the timer period timer can be sent both in the periodic broadcast transmission and the timed transmission according to actual demand, the system information is retransmitted in the fixed timer, and the value of the timer can be set according to the demand of the terminal or the network side, for example, can be set to 40ms or 80 ms. Note that, as for the system information MIB and SIB1, a transmission mode in which only periodic broadcast transmission is performed is generally set. The priority comprises three levels of setting, wherein SIB 6-SIB 8 is set to be 0 when the natural disaster, emergent emergency and the like are faced, so the priority is the highest; MIB-SIB 1 is used as basic system information, the priority of which is most important and is set to 1; the priority of the other system information is set to 2. Of course, the method for distinguishing priority in setting is not limited to the above numerical values in this embodiment, and other methods for performing priority division on system information are within the scope of the present disclosure.
The method for acquiring system information provided by the present disclosure relates to specific scheduling parameters including:
(1) SI-Broadcast Status (system information Broadcast Status): the transmission mode of the scheduled state of SIB1, i.e., the transmission mode in the scheduling information in SIB1, is indicated. If the field is set to 1, it indicates that the field is set to broadcast (periodic broadcast); if the field is set to 2, the on-demand SI mode is set; if the field is set to 3, indicating that unicast mode is set; with a default value of 1. It should be noted that other fields that are convenient for distinguishing the three transmission modes belong to the protection scope of the present disclosure.
(2) systemlnformationareaid (system information area identification): indicating the system information area to which the current cell belongs.
(3) Value Tag in SIB-Type Info: the scheduled state is represented, the value is 0-31, and when the system information after the terminal change is consistent with the stored original SI-Window information, the system information is represented to be unchanged, and the value Tag value is unchanged; and when the terminal change system information is inconsistent with the stored original SI-Window information, the value Tag value is + 1.
(4) systemlnformatimeter (number of times of system information): and if the change times of the sending system information is shown and the system information is changed together, the timer value is + 1.
(5) system information priority: the method comprises the steps of representing scheduling priorities, wherein SIB 6-SIB 8 are system information facing natural disasters, emergent emergencies and the like, the priority is the highest, and the field is set to be 0; MIB-SIB 1 is used as basic system information, the priority is most important, and the field is set to 1; and other system information sends changes according to the service requirements, and the field is set to be 2.
As shown in fig. 1, the method for acquiring system information includes the following steps:
In this embodiment, the service change includes a service change initiated by a terminal or a service change initiated by a network side, and the terminal and the network side know the currently occurring service change through signaling interaction, where the specific content of the service change includes that the terminal initiates continuous paging, location change or terminal capability change, and the terminal receives a system information change notification, receives an indication of an ETWS notification, and so on. In addition, the types of the services include a service related to mobile handover and a service related to RRC connection, such as a signaling flow of System Information (SI) transmission/reception shown in fig. 2:
the signaling in the first solid line box is system information change message signaling, and when the system information is changed, signaling interaction is sent to a base station at a network side through a terminal for transmission;
the signaling in the second dotted line block is an RRC connection signaling, and when the terminal changes system information during RRC connection, signaling interaction is sent to the terminal through a base station on the network side for transmission;
and the signaling in the third solid line box is Handover signaling, and when the terminal sends a system information change during Handover, the signaling is sent to the base station at the network side through the terminal for interactive transmission.
In an embodiment, as shown in fig. 3, when a service is changed, system information sent by a network side is received and stored in a system information message pool, and it is determined whether the service is a change of a system information area id to which a current cell belongs: if yes, changing the number of times of the service by +1, judging whether the total number of times of the service is larger than a first threshold value, if not, setting the sending mode of the system information of the service as periodic sending, and determining to send a switching request to a network side, wherein the switching request comprises the sending mode of the system information of the service; if the judgment result is yes, the sending mode of the system information of the service is set to be sent according to the requirement or sent in a unicast mode, and a switching request is determined to be sent to the network side, wherein the switching request comprises the sending mode of the system information of the service.
In this embodiment, when the service is changed, the terminal can receive the changed system information sent by the network-side base station, and comparing the changed system information with the original system information stored in the system information message pool, if the comparison result is not consistent, the changed system information is stored in a system information message pool, specifically, the terminal stores the current latest system information, the system information includes the most important and commonly used transmission parameters, system information scheduling information, relevant information of other cell access, radio resource configuration information common to the terminal, co-frequency/inter-frequency cell reselection parameters and the like, wherein, each system information corresponds to one SI-Window, after the terminal receives each system information sent by the base station, each system information is stored in a corresponding SI-Window, and the current latest SI-Windows are stored together to form an SI message pool.
It can be seen that, when the service is changed, the terminal first judges whether the system information requirement and the information stored in the SI message pool meet the service requirement (i.e. the number of changes is less than or equal to the first threshold) when the service is changed, and if the service change requirement is met, the original sending mode (periodic sending) is maintained to continue sending the system information; if the service change requirement cannot be met (namely the change times are greater than a first threshold), determining the type of the service, and determining a sending mode of system information corresponding to the service according to the change times of the service.
Specifically, it is first determined whether the service is a change of the system information area id to which the current cell belongs: if yes, changing the number of times of the service by +1, namely, systemlnformatimeter +1, and because the area ID of the system information is changed, the changed system information is inconsistent with the original SI-Window information stored in the system information message pool, therefore, value Tag + 1, when the same service change occurs again, the number of times of the change of the service continues by +1, thus realizing the judgment and accumulation of multiple changes for the same service. It should be noted that the accumulation refers to accumulating the number of times of change of the same service after the terminal is powered on, and when the terminal is powered on again, the number of times of change of the service needs to be recalculated. Then judging whether the total change times of the service after the terminal is started up is larger than a first threshold value, if the total change times is smaller than or equal to the first threshold value, setting the sending mode of the system information of the service as periodic sending, namely, modifying an SI-Window Window according to the service, setting SI-Broadcast Status as 1, and determining to send a switching request to a network side, wherein the switching request comprises the sending mode (namely, periodic sending) of the system information of the service; if the total change times is larger than the first threshold value, the sending mode of the system information of the service is set to be sent as required or sent in a unicast mode, that is, the SI-Window is modified according to the service, and SI-Broadcast Status is set to be 2 or 3, and it is determined to send a switching request to the network side, where the switching request includes the sending mode (i.e., on-demand or unicast sending) of the system information of the service, basic information, and other changed SIBs.
It should be noted that the first threshold is a parameter, and can be set according to the requirements of the terminal or the network side base station, and when performing the setting, factors such as preventing a network signaling storm and ensuring that the terminal can receive correct system information need to be comprehensively considered.
For example: if the first threshold is 5, when the service change terminal performs a handover between cell a and cell B, the terminal receives MIB, SIB1, SIB2, SIB3, SIB4, and SIB5 transmitted by the network side base station, and determines that the service is a change of a system information area (area id) to which the current cell belongs as a result of the determination, then systemlnformatizer +1, value Tag + 1, modifies the SI-Window according to the service, sets SI-Broadcast Status to 1, and determines to transmit a handover request to the network side, where the handover request includes a transmission mode (i.e., periodic transmission) of the system information of the service. When the terminal performs multiple handovers between the cell a and the cell B, and the number of handovers is greater than 5, the transmission mode of the system information of the service is set to be on-demand transmission or unicast transmission, that is, the SI-Window is modified according to the service, and the SI-Broadcast Status is set to 2 or 3, and it is determined to transmit a handover request to the network side, where the handover request includes the transmission mode of the system information of the service (i.e., on-demand or unicast transmission), MIB, SIB1, changed SIB2, changed SIB3, changed SIB4, and changed SIB 5. When the system information sending mode that the network side base station receives the system information sent by the terminal is periodic sending, the base station can retransmit the system information to the terminal in a fixed timer so as to ensure that the terminal can receive accurate system information. When the network side base station receives that the system information sending mode sent by the terminal is sending according to the requirement, and when the base station receives service requests of SIB 2-SIB 5 sent by the terminal, the base station can retransmit the system information to the terminal in a fixed timer, so as to ensure that the terminal receives accurate system information on time. When the network side base station receives that the system information transmission mode transmitted by the terminal is unicast transmission and the base station receives service requests of SIB 2-SIB 5 transmitted by the terminal, the base station transmits the system information to the terminal once, so that the terminal receives accurate system information. The system information comprises MIB, SIB1, SIB 2-SIB 5. Therefore, the terminal does not need to read the system information frequently, so that the terminal can receive the required correct system information on time, and network resources can be saved.
Specifically, the step of judging whether the service is the change of the system information area to which the current cell belongs includes detecting the system information area to which the current cell belongs, comparing whether the system information area to which the current cell belongs is consistent with the system information area id stored in the system information message pool, and if the comparison result is consistent, judging that the result is yes; if the comparison result is not consistent, judging whether the result is negative.
In this embodiment, if the system information area id to which the current cell belongs is identical to the system information area id stored in the system information message pool, it is described that the service change is not performed for the mobile handover. If the system information area id to which the current cell belongs is not consistent with the system information area id stored in the system information message pool, the service change of the mobile handover is described.
In one embodiment, the determining whether the service is a change of a system information area id to which the current cell belongs further includes:
if the area of the system information is not changed, further judging whether the system information after the service change is consistent with the corresponding system information stored in the system information message pool or not: if the system information is consistent with the service information, the change times of the service is +1, whether the total change times of the service is larger than a second threshold value or not is judged, if the total change times of the service is not larger than the second threshold value, the sending mode of the system information of the service is set to be periodic sending, and an RRC change request is determined to be sent to the network side, wherein the RRC change request comprises the sending mode of the system information of the service; if the judgment result is yes, setting the sending mode of the system information of the service as on-demand sending or unicast sending, and determining to send an RRC change request to the network side, wherein the RRC change request comprises the sending mode of the system information of the service; if the system information of the service is inconsistent with the system information of the service, the change frequency of the service is +1, whether the total change frequency of the service is greater than a third threshold value or not is judged, if the total change frequency of the service is not greater than the third threshold value, the sending mode of the system information of the service is set to be periodic sending, and an RRC change request is determined to be sent to a network side, wherein the RRC change request comprises the sending mode of the system information of the service; and if so, setting the transmission mode of the system information of the service to be on-demand transmission or unicast transmission, and determining to transmit an RRC change request to the network side, wherein the RRC change request comprises the transmission mode of the system information of the service.
In this embodiment, when the system information area is not changed and the changed system information of the service is consistent with the corresponding system information stored in the system information message pool as a result of the determination, the number of times of change of the service is +1, that is, systemlnformatizer +1, and since the system information area is not changed and the changed system information is consistent with the original SI-Window information, the value Tag is not changed, and when the same service change occurs again, the number of times of change of the service continues +1, so that determination and accumulation of multiple changes for the same service can be implemented. Then, judging whether the total change times of the service after the terminal is started up is larger than a second threshold value, if the total change times is smaller than or equal to the second threshold value, setting the sending mode of the system information of the service as periodic sending, namely, according to the service modification SI-Window, setting SI-Broadcast Status as 1, determining to send an RRC change request to the network side, wherein the RRC change request comprises the sending mode (namely, periodic sending) of the system information of the service; and if the total change frequency is larger than the second threshold value, setting the transmission mode of the system information of the service as on-demand transmission or unicast transmission, namely modifying an SI-Window Window according to the service, setting SI-Broadcast Status to be 2 or SI-Broadcast Status to be 3, and determining to transmit an RRC change request to the network side, wherein the RRC change request comprises the transmission mode (on-demand or unicast transmission), basic information and other changed SIBs of the system information of the service.
It should be noted that the second threshold is a parameter, and can be set according to the requirements of the terminal or the network side base station, and when performing the setting, factors such as preventing a network signaling storm and ensuring that the terminal can receive correct system information need to be comprehensively considered.
For example, if the second threshold is 50, when the service is changed to the user a where the terminal is located to page the user C, the terminal may receive the MIB, SIB1, and SIB2 sent by the network side base station, where the content in the system information includes a paging message, and the terminal sets the transmission mode of the system information of the service to be periodic transmission, that is, according to the service, the SI-Window is modified, and set SI-Broadcast Status to 1, it is determined to send an RRC change request to the network side, where the RRC change request includes the transmission mode of the system information of the service (i.e., periodic transmission). When the user a is continuously talking with the user C and the systemlnformationtimer is greater than 50 times, the terminal sets the transmission mode of the system information of the service to be on-demand transmission or unicast transmission, namely, modifies the SI-Window according to the service, sets SI-Broadcast Status to 2 or SI-Broadcast Status to 3, and determines to transmit an RRC change request to the network side, where the RRC change request includes the transmission mode (i.e., on-demand or unicast transmission), MIB, SIB1, and changed SIB2 of the system information of the service. When the system information sending mode that the network side base station receives the system information sent by the terminal is periodic sending, the base station can retransmit the system information to the terminal in a fixed timer so as to ensure that the terminal can receive accurate system information. When the network side base station receives that the system information sending mode sent by the terminal is sending according to needs, and when the base station receives the SIB2 service request sent by the terminal, the base station can retransmit the system information to the terminal in a fixed timer, so as to ensure that the terminal receives accurate system information on time. When the network side base station receives that the system information transmission mode transmitted by the terminal is unicast transmission, and when the base station receives the service request of the SIB2 transmitted by the terminal, the base station transmits the system information to the terminal once, so that the terminal receives accurate system information. The system information comprises MIB, SIB1 and SIB 2. Therefore, the terminal does not need to read the system information frequently, so that the terminal can receive the required correct system information on time, and network resources can be saved.
In addition, when the judgment result is that the area of the system information is not changed, and the changed system information of the service is not consistent with the corresponding system information stored in the system information message pool, the changed number of times of the service is +1, namely, systemlnformatizer +1, and the changed system information is not consistent with the stored original SI-Window information, so the value Tag + 1, and when the same service is changed again, the changed number of times of the service continues to be +1, so that the judgment and the accumulation of the multiple changes of the same service can be realized. Then, judging whether the total change times of the service after the terminal is started up is larger than a third threshold, if the total change times is smaller than or equal to the third threshold, setting the sending mode of the system information of the service as periodic sending, namely, according to the service modification SI-Window, setting SI-Broadcast Status as 1, determining to send an RRC change request to the network side, wherein the RRC change request comprises the sending mode (namely, periodic sending) of the system information of the service; and if the total change frequency is larger than the third threshold value, setting the transmission mode of the system information of the service as on-demand transmission or unicast transmission, namely modifying an SI-Window Window according to the service, setting SI-Broadcast Status to be 2 or SI-Broadcast Status to be 3, and determining to transmit an RRC change request to the network side, wherein the RRC change request comprises the transmission mode (on-demand or unicast transmission), basic information and other changed SIBs of the system information of the service.
It should be noted that the third threshold is a parameter, and can be set according to the requirements of the terminal or the network side base station, and when performing the setting, factors such as preventing a network signaling storm and ensuring that the terminal can receive correct system information need to be comprehensively considered.
For example, if the third threshold is set to 10, when the service is changed to that the user a and the user C in which the terminal is located receive a call request from in-terminal social software (e.g. WeChat, QQ) during the call, the terminal receives the MIB, SIB1, SIB2 sent by the network side base station, since the new service is a call request from the social software, the terminal receives the new service information sent by the network side, therefore, the service change makes the changed system information inconsistent with the stored original SI-Window information, the terminal sets the transmission mode of the system information of the service as periodic transmission, namely, according to the service, the SI-Window is modified, the SI-Broadcast Status is set as 1, the RRC change request is determined to be sent to the network side, the RRC change request includes a transmission mode (i.e., periodic transmission) of the system information of the service. When a user a receives a call request of social software for multiple times within a certain preset time length and the systemlnformatiometer is greater than 10 times, the terminal sets the sending mode of the system information of the service to be sent as required or sent in a unicast mode, namely, according to the service, the SI-Window is modified, the SI-Broadcast Status is set to be 2 or the SI-Broadcast Status is set to be 3, and the terminal determines to send an RRC change request to the network side, wherein the RRC change request includes the sending mode (i.e., on-demand or unicast sending) of the system information of the service, MIB, SIB1 and changed SIB 2. When the system information sending mode that the network side base station receives the system information sent by the terminal is periodic sending, the base station can retransmit the system information to the terminal in a fixed timer so as to ensure that the terminal can receive accurate system information. When the network side base station receives that the system information sending mode sent by the terminal is sending according to needs, and when the base station receives the SIB2 service request sent by the terminal, the base station can retransmit the system information to the terminal in a fixed timer, so as to ensure that the terminal receives accurate system information on time. When the network side base station receives that the system information transmission mode transmitted by the terminal is unicast transmission, and when the base station receives the service request of the SIB2 transmitted by the terminal, the base station transmits the system information to the terminal once, so that the terminal receives accurate system information. The system information comprises MIB, SIB1 and SIB 2. Therefore, the terminal does not need to read the system information frequently, so that the terminal can receive the required correct system information on time, and network resources can be saved.
