Description

TECHNICAL FIELD

[0001] The present application relates to the field of mobile communication technology, and in particular to a receiving method and a sending method of system information, a terminal and a base station. BACKGROUND

[0002] In a cellular system, system information (SI) refers to the common information of a cell or multiple cells. Since the content of SI is relatively large, SI is divided into system information blocks (SIBs) according to characteristics, and each SIB contains SI of the same characteristic. For example, SIB1 mainly contains timer and counter parameter information of a user equipment (UE) in an idle mode.

[0003] The position and period of a master information block (MIB) and SIB1 in a long term evolution (LTE) system in a time domain are fixed, and the position and period of an SI message in the time domain are specified by SIB1. SI collects SIBs with the same characteristic into a scheduling unit (SU), which is used to put SIBs with the same scheduling characteristic together, and is equivalent to a container. The SU is a basic unit of system information scheduling in the LTE system. The same characteristic here mainly refers to a period of information repetition. An eNodeB tells a UE which SI is included, which SIB is contained in each SI, and in which SI window the SI is sent, and the time domain position and length of the SI window, but does not tell the UE which subframe in the SI window schedules the SI. When the UE needs a SIB, it uses system information RNTI (SI-RNTI) to attempt to decode in each subframe of an SI window corresponding to the SIB (from the starting subframe of the SI window, and lasts for si-WindowLength subframes, but does not include subframes that cannot schedule SI), corresponding to the SI message of the SIB, until the SI message is successfully received.

[0004] The periodicity of SIB1 is 80 ms, and the same SIB1 is repeatedly transmitted on subframe 5 of the system frame with system frame number (SFN) % 2 = 0 in the periodicity. However, unlike the fixed time-frequency location of MIB, SIB1 and SI messages are both transmitted on PDSCH, and the RB (location in the frequency domain) occupied by SIB1 and SI messages and the transmission format thereof are dynamically scheduled, and are indicated by a physical downlink control channel (PDCCH) scrambled by an SI-RNTI.

[0005] Each SI message contains one or more SIBs other than SIB1 that have the same scheduling requirements (these SIBs have the same transmission periodicity). Which SIBs are contained in an SI message are specified by a scheduling information list (schedulingInfoList). Each SIB can only be contained in one SI message, and SIB2 is always placed in the first SI message item in the SI list specified by schedulingInfoList, so SIB2 is not specified in the SI in schedulingInfoList.

[0006] In the development process of the network from 4G to 5G, new SIBs may be added for broadcast transmission. For example, after the standalone network is modified to support interoperation and the 4G to 5G reselection function is enabled, the 4G base station needs to broadcast SIB24. The inventors have found that after SIB24 is broadcast, some 4G terminals in the existing network cannot access the LTE network and fall back to the 2G network, which seriously affects the network use of these terminals and causes user complaints. At the same time, after the SA modification, some 4G terminals using old versions of the chip add SIB24 (used for 4 / 5G reselection) to the LTE broadcast message, and when reading the LTE broadcast message (mainly SIB24), an abnormality occurs, which causes the terminal to fail to camp on the LTE network and fall back to the GSM network.

[0094] See Figure 1 , Figure 1 A block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a user terminal or a user equipment (UE), and the terminal 11 can be a terminal-side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), a wearable device, or a vehicle-mounted device, and it should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network device 12 can be a base station and / or a core network element, and the base station can be a base station of 5G and later versions (for example, a gNB, a 5G NR NB, or the like) or a base station in other communication systems (for example, an eNB, a WLAN access point, or other access points, and the like), and the base station can be referred to as a node B, an evolved node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the art, provided that the same technical effect is achieved, and the base station is not limited to a specific technical term, and it should be noted that only the base station in the NR system is taken as an example in the embodiments of the present application, but the specific type of the base station is not limited.

[0095] The base stations can communicate with the terminals 11 under the control of a base station controller, which can be part of the core network or of certain base stations in various examples. Some of the base stations can communicate control information or user data with the core network through backhaul links. In some examples, some of these base stations can communicate with one another through backhaul links, which can be wired or wireless communication links. The wireless communications system can support operation on multiple carriers (waveform signals of different frequencies). Multi-carrier transmitters can transmit modulated signals simultaneously on the multiple carriers. For example, each communication link can be a multi-carrier signal modulated according to the various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0096] The base stations can wirelessly communicate with the terminals 11 via one or more access point antennas. Each base station can provide communication coverage for a respective coverage area. The coverage area for an access point can be divided into sectors making up only a portion of the coverage area. The wireless communications system can include base stations of different types (e.g., macro, micro, or pico base stations). The base stations can utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations can be associated with the same or different access networks or operator deployments. The coverage areas of different base stations, including the coverage areas of base stations of the same or different types, utilizing the same or different radio technologies, or belonging to the same or different access networks, can overlap.

[0097] Communication links in a wireless communications system can include uplinks for carrying uplink (UL) transmissions (e.g., from a terminal 11 to a network device 12) or downlinks for carrying downlink (DL) transmissions (e.g., from a network device 12 to a terminal 11). UL transmissions can also be called reverse link transmissions, and DL transmissions can also be called forward link transmissions. Downlink transmissions can be made using a licensed spectrum, an unlicensed spectrum, or both. Similarly, uplink transmissions can be made using a licensed spectrum, an unlicensed spectrum, or both.

[0098] As described in the background, in the prior art, after the present network adds the scheduling information of SIB24 in SIB1, some inventory terminals in the present network can not support receiving SIB24 and abnormality occurs, at this time, the terminal can bar the normal and legal cell, thereby causing the terminal to be unable to access the LTE network, and seriously affecting the use experience of the terminal to the network. To solve at least one of the above problems, the embodiment of the present application provides a receiving method and a sending method of system information, which can reduce or avoid the occurrence of the above situation and improve the use experience of the terminal to the network.

[0099] Please refer to Figure 2 The system information receiving method provided by the embodiment of the present application can avoid the problem of reading abnormity caused by adding the scheduling information of the specific SIB in SIB1 directly by sending the specific SIB in the embedded hierarchical scheduling manner of the system message. As shown in the figure, Figure 2 When applied to the terminal side, the system information receiving method comprises the following steps:

[0100] In step 21, the terminal receives SIBm according to the scheduling information of SIBm, and acquires the scheduling information of SIBn carried by SIBm.

[0101] In the embodiment of the present application, the terminal can receive SIB1 sent by the base station, and SIB1 usually carries the scheduling information of a plurality of SIBs, wherein the plurality of SIBs are other SIBs except SIB1. The terminal can receive SIBm according to the scheduling information of SIBm read from SIB1. In the embodiment of the present application, SIBm adds the scheduling information of SIBn in addition to carrying the content of the SIB itself, so that the terminal can acquire the scheduling information of SIBn when receiving SIBm. The m and n are both integers greater than 1. For example, the SIBn is SIB24, and the SIBm is SIB3.

[0102] In this article, SIBm and SIBn are both other SIBs than SIB1. Since the information carried in the master information block (MIB) is only a part of the system information, most of the system information needs to be sent through SIBs. In addition to sending the MIB, the base station will usually send several different types of SIBs as needed, which provide the terminal with several parameters required for cell camping, retransmission, link establishment, etc. Taking the LTE system as an example, there are many types of SIBs, including SIB1, SIB2, SIB3, SIB4, SIB5, SIB6, SIB7, SIB8, SIB9, SIB10, SIB11, SIB12, SIB13, etc. Moreover, more SIBs can be defined according to the evolution of the communication system. Among them, SIB1 mainly carries cell access and cell selection related information, and can also carry subframe configuration, scheduling and window information of other SIB blocks, etc. SIB2 mainly carries public wireless resource configuration related information. SIB3 mainly carries common information related to intra-frequency, inter-frequency and cross-standard cell reselection. SIB4 mainly carries neighbor cell information for intra-frequency cell reselection. SIB5 mainly carries neighbor cell information for inter-frequency cell reselection, etc. Among them, the most important SIB is SIB1, because SIB1 carries not only the parameters required for UE to access the cell, but also the scheduling information of other SIB types. If the terminal cannot decode SIB1, it cannot decode other types of SIBs. Based on this, the base station in the prior art usually broadcasts SIBs in two different ways: the first is to broadcast SIB1 through a SystemInformationBlockType1 message cycle, and the second is to broadcast other SIBs except SIB1 through multiple SI message cycles.

[0103] The scheduling information of the SIBn includes at least one of the following information: a mapping relationship between the SIBn and system information SI, a scheduling period of the SI corresponding to the SIBn, beam information of the SI corresponding to the SIBn, bandwidth part (BWP) information of the SI corresponding to the SIBn, transport block size (TBS) information of the SI corresponding to the SIBn, and length and offset parameters of an SI window corresponding to the SIBn.

[0104] Optionally, the SIBm can also carry indication information of whether the SIBn changes.

[0105] Optionally, the SIBm can also carry indication information of whether the SIBn needs to be sent in segments.

[0106] Optionally, the SIBm can also carry indication information of whether the SIBn changes and indication information of whether the SIBn needs to be sent in segments.

[0107] Optionally, the scheduling information of the SIBn can further carry indication information of whether the SIBn changes.

[0108] Optionally, the scheduling information of the SIBn can further carry indication information of whether the SIBn needs to be sent in segments.

[0109] Optionally, the scheduling information of the SIBn can further carry indication information of whether the SIBn changes and indication information of whether the SIBn needs to be sent in segments.

[0110] Step 22, the terminal receives the SIBn according to the scheduling information of the SIBn.

[0111] Here, the terminal can receive the SIBn according to the scheduling information of the SIBn obtained from the SIBm. Optionally, the SIBn can contain information related to inter-system cell reselection. In this way, the terminal can obtain information related to inter-system cell reselection from the received SIBn.

[0112] Figure 3 An example of the embedded hierarchical scheduling of the embodiment of the present application is given, taking the scheduling information of the SIB24 carried in the SIB3 as an example. In the example, the information related to the SI window 3 corresponding to the SIB3 is indicated in the SIB1, the terminal can detect and receive the SIB3 in the SI window 3, and obtain the content of the SIB3 and the information related to the SI window 24 corresponding to the SIB24, so as to detect and receive the SIB24 in the SI window 24.

[0113] When the indication information of whether the SIBn changes is carried in the scheduling information of the SIBm or the SIBn, the terminal of the embodiment of the present application can determine whether the SIBn changes according to the indication information, and when the SIBn changes, receive the SIBn according to the scheduling information of the SIBn, and when the SIBn does not change, do not receive the SIBn, so as to save the receiving processing flow on the terminal side and reduce the power consumption of the terminal.

[0114] By the above mode, the embodiment of the present application introduces an embedded hierarchical scheduling mode, SIBn is sent through SIBm, the problem of system information reading abnormality of the old version terminal possibly caused by adding the scheduling information of SIBn in SIB1 directly is reduced or avoided, the communication reliability of the network is ensured, and the service quality of the terminal is improved. For the terminal (such as the terminal of the old version of the use stock chip in the present network) that does not need SIBn, the scheduling information of SIBn carried in SIBm can be directly ignored, that is, SIBn is not received. For the terminal that needs SIBn, SIBn can be received according to the scheduling information of SIBn carried in SIBm, and the required system information, such as the related information of inter-system cell reselection, is acquired, thereby supporting the interoperation of the 4G network to the 5G network.

[0115] Please refer to Figure 4 The embodiment of the present application further provides a system information sending method applied to the base station side, comprising the following steps:

[0116] In step 41, the base station sends the SIBm according to the scheduling information of the SIBm, and the SIBm carries the scheduling information of the SIBn.

[0117] In the embodiment of the present application, the base station can send SIB1, and the SIB1 carries the scheduling information of SIBm. The SIB1 usually carries the scheduling information of a plurality of SIBs, and the plurality of SIBs are usually other SIBs except SIB1. Here, the SIBm can be SIB3, SIB4, etc. The m and n are both integers greater than 1.

[0118] The base station sends SIBm according to the scheduling information of SIBm. In the embodiment of the present application, SIBm not only carries the content of the SIB itself, but also adds the scheduling information of SIBn. The SIBn can be SIB24 and other SIBs.

[0119] The scheduling information of the SIBn includes at least one of the following information: the mapping relationship between SIBn and system information SI, the scheduling period of the SI corresponding to SIBn, the beam information of the SI corresponding to SIBn, the bandwidth part (BWP) information of the SI corresponding to SIBn, the transport block size (TBS) information of the SI corresponding to SIBn, the length and offset parameters of the SI window corresponding to SIBn;

[0120] Optionally, the SIBm can also carry the indication information of whether SIBn changes.

[0122] Optionally, the SIBm can also carry indication information about whether the SIBn has changed, and indication information about whether the SIBn needs to be sent in segments.

[0123] Optionally, the scheduling information of the SIBn can also carry indication information about whether the SIBn has changed.

[0125] Optionally, the scheduling information of the SIBn can also carry indication information about whether the SIBn has changed, and indication information about whether the SIBn needs to be sent in segments.

[0126] Step 42, the base station sends the SIBn message according to the scheduling information of the SIBn.

[0127] Here, the base station can send the SIBn according to the scheduling information of the SIBn. Optionally, the SIBn can contain information about inter-system cell reselection. In this way, the base station can send the information about inter-system cell reselection to the terminal through the SIBn.

[0128] In the above manner, the embodiment of the application introduces an embedded hierarchical scheduling mode, sends the SIBn through the SIBm, reduces or avoids the problem that the abnormal system information reading of the old version terminal can be caused by adding the scheduling information of the SIBn in the SIB1 directly, guarantees the communication reliability of the network, and improves the service quality of the terminal.

[0129] In addition, in the embodiment of the application, when the scheduling information of the SIBn message is changed, the base station can also prohibit triggering the system message update or the paging message.

[0175] In some embodiments of the present application, a computer readable storage medium is also provided, which stores a program, and the program is executed by a processor to implement the following steps:

[0176] According to the scheduling information of the SIBm, the SIBm is sent, and the SIBm carries the scheduling information of the SIBn;

[0177] According to the scheduling information of the SIBn, the SIBn message is sent, and m and n are both integers greater than 1.

[0178] The program is executed by the processor to implement all the implementation manners in the above method for sending system information applied to the base station side, and the same technical effects can be achieved. To avoid repetition, this will not be described here.

[0179] Please refer to Figure 9 The other system information receiving method provided by the embodiment of the present application includes the following steps when applied to the terminal side:

[0180] Step 91, the terminal receives dedicated signaling, wherein the dedicated signaling carries SIBn of the first cell and the first neighboring cell in which the terminal resides.

[0181] Here, the dedicated signaling can be Radio Resource Control (RRC) signaling or other predefined signaling. For example, the dedicated signaling can be an RRC connection release message and / or a response message of a tracking area (TA) update, etc.

[0182] Here, the dedicated signaling carries SIBn of the first cell in which the terminal currently resides, and the SIBn of the first cell can include information related to inter-system cell reselection of the first cell. Specifically, for example, the SIBn can include SIB24 and other SIBs, and the information related to inter-system cell reselection can be carried in SIB24.

[0183] Considering that the terminal can reselect from one cell to another in an idle state or an inactive state, at this time, the network can not know the movement of the terminal and the current cell in which the terminal resides, thereby failing to timely send some SIBs to the terminal, such as the SIBs sent by the above-mentioned dedicated signaling. Therefore, the embodiment of the present application can also carry SIBn of the first neighboring cell in the dedicated signaling, at this time, the terminal can also obtain SIBn of the first neighboring cell from the dedicated signaling.

[0184] Here, the first neighboring cell is all or part of the neighboring cells of the first cell. The SIBn of the first neighboring cell can include information related to inter-system cell reselection of the first neighboring cell. Specifically, for example, the SIBn of the first neighboring cell can include SIB24 and other SIBs, and the information related to inter-system cell reselection of the first neighboring cell can be carried in SIB24.

[0185] For example, when the terminal is in an idle state, the first neighboring cell is a neighboring cell in a tracking area (TA) in which the terminal resides. When the terminal is in an inactive state, the first neighboring cell is a neighboring cell in a radio access network (RAN) notification area in which the terminal resides.

[0186] Step 92, the terminal obtains SIBn of the first cell and the first neighboring cell from the dedicated signaling.

[0187] Here, the terminal can directly receive the dedicated signaling and obtain SIBn of the first cell therefrom.

[0188] Through the above steps, the embodiment of the present application can not add the scheduling information of the SIBn of the first cell and the first neighbor cell in the SIB1, but directly send the added SIB through the dedicated signaling, so that the problem of system information reading abnormality of the old version terminal caused by directly adding the scheduling information of the SIBn in the SIB1 can be avoided, the communication reliability of the network is improved, and the service quality of the terminal is improved.

[0189] Optionally, the dedicated signaling also carries first indication information, and the first indication information is used to indicate whether the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell. Specifically, the above indication can be performed through the first indication information of at least one bit. For example, when the bit is 0, it indicates that the two are same, and when the bit is 1, it indicates that the two are different. Of course, when the bit is 1, it can also indicate that the two are same, and when the bit is 0, it indicates that the two are different.

[0190] Optionally, whether the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell can also be indicated by whether the dedicated signaling carries second indication information. The second indication information can be indicated by a certain predefined field in the dedicated signaling. When the dedicated signaling carries the second indication information, the field is included in the dedicated signaling, otherwise, when the dedicated signaling does not carry the second indication information, the dedicated signaling does not have the field.

[0191] For example, when the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell, the dedicated signaling carries the second indication information, otherwise, the dedicated signaling does not carry the second indication information. In this way, after receiving the dedicated signaling, the terminal can determine that the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell if the second indication information exists in the dedicated signaling, and can determine that the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell if the second indication information does not exist in the dedicated signaling.

[0192] Optionally, whether the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell can also be indicated by whether the dedicated signaling carries third indication information. The third indication information can also be indicated by a certain predefined field in the dedicated signaling. When the dedicated signaling carries the third indication information, the field is included in the dedicated signaling, otherwise, when the dedicated signaling does not carry the third indication information, the dedicated signaling does not have the field.

[0193] For example, when the information of the SIBn of the first neighbor cell is the same as the information of the SIBn of the first cell, the dedicated signaling can not carry the third indication information, otherwise, the dedicated signaling carries the third indication information. In this way, after receiving the dedicated signaling, if the second indication information does not exist in the dedicated signaling, the terminal can determine that the information of the SIBn of the first neighbor cell is the same as the information of the SIBn of the first cell; if the second indication information exists in the dedicated signaling, the terminal can determine that the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell.

[0194] In the embodiment of the present application, when the information of the SIBn of the first neighbor cell is the same as the information of the SIBn of the first cell, the first indication information can be sent to indicate the SIBn of the first neighbor cell without sending the whole content of the SIB.

[0195] In the embodiment of the present application, when the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell, the whole or part of the content of the SIBn of the first neighbor cell can be sent. When the part of the content of the SIBn of the first neighbor cell is sent, only the part of the SIBn of the first neighbor cell which is different from the SIBn of the first cell can be sent in the dedicated signaling, that is, only the different content of the two is sent without sending the same content of the two, so that the amount of information to be sent can be reduced and the signaling overhead can be saved.

[0196] For example, taking whether the second indication information is carried in the special signaling as an example to indicate whether the information of SIBn of the first neighbor cell is same as the information of SIBn of the first cell, when the information of SIBn of the first neighbor cell is same as the information of SIBn of the first cell, the field indicating SIBn of the first neighbor cell in the special signaling can only contain the second indication information, at this time, the terminal can judge that the information of SIBn of the first neighbor cell is same as the information of SIBn of the first cell, and directly acquires SIBn of the first neighbor cell according to SIBn of the first cell; while when the information of SIBn of the first neighbor cell is different from the information of SIBn of the first cell, the field indicating SIBn of the first neighbor cell in the special signaling can not contain the second indication information, but contains part of the information of SIBn of the first neighbor cell. Since the second indication information is not contained in the special signaling, the terminal can judge that the information of SIBn of the first neighbor cell is different from the information of SIBn of the first cell, and acquires the part of SIBn of the first neighbor cell which is different from SIBn of the first cell and is carried in the special signaling. For the remaining content of SIBn of the first neighbor cell (i.e. other content except the part of SIBn carried in the special signaling), the corresponding content in SIBn of the first cell can be directly used.

[0197] For example, if the third indication information is carried in the special signaling, the terminal can determine that the SIBn of the first neighboring cell is different from the SIBn of the first cell, and acquire the SIBn of the first neighboring cell from the special signaling. If the third indication information is not carried in the special signaling, the terminal can determine that the SIBn of the first neighboring cell is the same as the SIBn of the first cell, and acquire the SIBn of the first neighboring cell from the SIBn of the first cell.

[0198] Table 1 gives an example of information carried by the SIBn of the cell x sent through the special signaling. The left column of Table 1 is the relevant information element, and the left column is the specific content of the relevant information element. For example, the information of the SIBn of the cell x itself can be carried, which specifically includes the full configuration information of the SIBn of the cell x; the list of neighboring cells in the tracking area (TA) or the radio access network notification area (RAN area) where the cell x is located can also be carried, and the information of the SIBn of each neighboring cell in the list is carried respectively. In this table 1, only the parameter information of the SIBn of the neighboring cell which is different from the SIBn of the cell x is sent, which also reduces the signaling overhead.

[0199]

[0200]

[0201] Table 1

[0202] Please refer to Figure 10 The method for receiving system information provided by the embodiment of the present application comprises the following steps when applied to the base station side:

[0203] In step 101, the base station sends special signaling to the terminal, and the special signaling carries the SIBn of the first cell and the first neighboring cell in which the terminal resides.

[0204] Here, the special signaling can specifically include an RRC connection release message and / or a response message of zone TA update. The SIBn of the first cell can include information related to inter-system cell reselection of the first cell. Specifically, the SIBn can include SIB24.

[0205] The special signaling also carries the SIBn of the first neighbor cell. For example, when the terminal is in an idle state, the first neighbor cell is a neighbor cell in a tracking area in which the terminal is located; when the terminal is in an inactive state, the first neighbor cell is a neighbor cell in a radio access network notification area in which the terminal is located.

[0206] Through the above steps, the embodiment of the application can directly send some SIBs, such as a newly added SIB, to a terminal through special signaling, thereby avoiding network access problems caused by information reading abnormalities of some old version terminals due to the addition of scheduling information of SIBn in SIB1, and improving the use experience of the terminal to the network.

[0207] Optionally, the special signaling also carries first indication information, and the first indication information is used to indicate whether the information of the SIBn of the first neighbor cell is the same as the information of the SIBn of the first cell.

[0208] Optionally, when the information of the SIBn of the first neighbor cell is the same as the information of the SIBn of the first cell, the special signaling carries second indication information, otherwise, the special signaling does not carry the second indication information.

[0209] Or,

[0210] When the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell, the special signaling carries third indication information, otherwise, the special signaling does not carry the third indication information.

[0211] In addition, in order to reduce signaling overhead, when the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell, the target SIB of the first neighbor cell carried in the special signaling is: a part of the SIBn of the first neighbor cell that is different from the first cell.

[0212] For example, taking whether the second indication information is carried in the special signaling as an example, to indicate whether the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell, when the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell, the field indicating the SIBn of the first neighbor cell in the special signaling can only contain the second indication information; and when the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell, the field indicating the SIBn of the first neighbor cell in the special signaling sent by the base station can not contain the second indication information, but only contain part of the information of the SIBn of the first neighbor cell.

[0213] For example, taking whether the third indication information is carried in the special signaling as an example, to indicate whether the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell, when the information of the SIBn of the first neighbor cell is same as the information of the SIBn of the first cell, the field indicating the SIBn of the first neighbor cell in the special signaling can be empty, that is, does not contain the third indication information, and does not contain the content of the SIBn of the first neighbor cell; and when the information of the SIBn of the first neighbor cell is different from the information of the SIBn of the first cell, the field indicating the SIBn of the first neighbor cell in the special signaling can contain the third indication information, and also contain part of the information of the SIBn of the first neighbor cell.

[0214] The above introduces various methods of the embodiments of the present application. The following will further provide a device for implementing the above method.

[0217] An obtaining module 112 is used for obtaining SIBn of the first cell and the first neighbor cell from the special signaling, and n is an integer greater than 1.

[0218] Optionally, when the terminal is in an idle state, the first neighbor cell is a neighbor cell in a tracking area TA in which the terminal resides; and when the terminal is in an inactive state, the first neighbor cell is a neighbor cell in a radio access network notification area RAN in which the terminal resides.

[0227] Optionally, the SIBn contains information related to inter-system cell reselection.
