Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method, apparatus, electronic device, and chip. Background Art

[0002] A terminal device (User Equipment, UE) needs to find a target cell on a frequency point when searching for a network. After synchronizing with the target cell, it reads the corresponding Master Information Block (MIB) and System Information Block Type 1 (SIB1) of the target cell. The UE will perform a residence check based on the residence information in the SIB1, and can only reside in the target cell after the check is successful.

[0003] Currently, during the residence check process, the frequency point information selected by the current cell is compared with the freqBandIndicator or MultiBandInfoList in the SIB1. If the current frequency point is included in the frequency band (BAND) corresponding to the freqBandIndicator or MultiBandInfoList, it can reside. If the current frequency point is not in the frequency band indicated by the freqBandIndicator and MultiBandInfoList, then it cannot reside in this cell, and the UE will continue to search for cells on other frequency points and try to reside.

[0004] However, since there may be a situation where cells are deployed in an overlapping area between different frequency bands, in the network selection process specified by 3GPP, when a target cell belonging to another frequency band is detected during the search for a frequency band, it is necessary to re-search the frequency band where the target cell is located to reside in the target cell, which will result in multiple searches being required to reside in the target cell, thereby causing a large consumption of time resources and computing resources and affecting the user experience. Summary of the Invention

[0028] The embodiments of the present disclosure will be described in more detail below with reference to the drawings. It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0029] In order to improve the technical problem that in the current existing technology, when searching for a target cell belonging to other frequency bands during cell reselection, it is necessary to re-search the frequency band where the target cell is located in order to camp on the target cell, which will lead to multiple searches being required to camp on the target cell, thereby causing a large consumption of time resources and computing resources and affecting the user experience. This embodiment provides a communication method, as Figure 1 shown, the method includes:

[0030] Step 101, in response to a target cell searched by a target frequency point during the cell reselection process of a terminal device, obtain target frequency band information corresponding to the target cell to be camped on.

[0031] In the embodiments of the present application, the method shown in the present application can be executed by a terminal device. The terminal device can be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device can also be an automobile with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, or can also be a chip or a chip system, etc. The specific technologies and specific device forms adopted by the terminal device in the embodiments of the present disclosure are not limited.

[0032] In some examples, in a mobile communication system, cell reselection refers to the process by which a terminal device selects and connects to a specific cell for communication. Cell reselection is the first step for the terminal device to access the network and is also the basis for the terminal device to maintain a connection in the mobile communication network. It is a key step for the terminal device to access the network. Among them, the terminal device obtains time synchronization by detecting the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS), and obtains the necessary system information by decoding the Master Information Block (MIB) and the System Information Blocks (SIBs), and finally selects a suitable cell for reselection. This process ensures that the UE can successfully access the network and maintain good communication quality.

[0033] Optionally, a frequency point refers to a specific frequency or frequency range used to identify the radio frequency used by one or more cells. Specifically, during the cell reselection process, the UE obtains time synchronization by searching for a specific frequency point, and obtains the necessary system information by reading the MIB and SIBs, and finally selects a suitable cell for reselection.

[0034] In the embodiments of the present application, a frequency band refers to a set of specific frequency ranges used to specify the radio frequency of mobile communication services. A frequency band is a basic concept in a mobile communication network, which defines the available frequency resources in wireless communication.

[0035] For this embodiment, a cell refers to a specific geographical area covered by a base station and is the basic service unit of a mobile communication network. A cell is a core concept in a mobile communication network, which allows the base station to provide wireless access services to users within a certain area.

[0036] It should be noted that the target frequency point in the embodiments of the present application can be the available frequency points that the terminal device searches for when it powers on or enters a new coverage area. Correspondingly, the cell to be reselected can be the cell where the available frequency points searched by the terminal device are located, and the target frequency band information is the frequency band information broadcast by the cell to be reselected, which can specifically include a frequency band indicator (freqBandIndicator) and a multi-band information list (MultiBandInfoList).

[0037] Specifically, the MultiBandInfoList is a list used to describe the detailed configuration information of multiple frequency bands in a mobile communication system. This list usually appears in the System Information Block (SIB1) to help the User Equipment (UE) determine the specific configuration information of available frequency bands, including the center frequency, bandwidth, duplex mode, etc. of the frequency bands. The MultiBandInfoList is an important parameter in SIB1, and the UE parses this information to determine which frequency bands are available and understand the specific configuration of each frequency band.

[0038] Correspondingly, the MultiBandInfoList is an important parameter in SIB1, which is used to describe the detailed configuration information of multiple frequency bands. The UE parses this information to determine which frequency bands are available and understand the specific configuration of each frequency band.

[0039] Exemplarily, in response to the target cell searched by the terminal device through the target frequency point during the cell residence process, obtaining the target frequency band information corresponding to the target cell may be that during the process of attempting to reside on the target cell after the terminal device searches for the target cell through the target frequency point, it is necessary to read the frequency band information broadcast by the target cell.

[0040] Step 102: If it is determined that the target frequency point is not included in the target frequency band information, convert the target frequency point into a frequency point that can be resided on.

[0041] Among them, the frequency point that can be resided on is used for the terminal device to reside on the target cell.

[0042] In some examples, based on Step 101, if the target frequency point is not included in the frequency band information broadcast by the target cell read, it is necessary to convert the target frequency point and convert the target frequency point into a frequency point that can be resided on.

[0043] The specific process may include determining the frequency bands supported by the terminal device in the frequency band information broadcast by the target cell, and converting the frequency point that the terminal device attempts to reside on from the target frequency point to a frequency point in the frequency bands supported by the terminal device, which is the frequency point that can be resided on.

[0044] It should be noted that the frequency point that can be resided on is a frequency point in the frequency bands supported by the terminal device in the frequency band information broadcast by the target cell.

[0045] Compared with the current existing technologies, in this embodiment, when it is determined that the target frequency point is not included in the target frequency band information, for cells with BAND mismatch, frequency conversion is performed, converting the target frequency point into a frequency point that can be resided on, and then the terminal device resides through the frequency point that can be resided on. This can effectively reduce the consumption of time resources and computing resources brought by network selection, enable the terminal device to quickly reside on the cell, conduct normal services, and improve the user experience.

[0046] Further, to illustrate the specific implementation process of the method in this embodiment, this embodiment provides a specific method as shown in Figure 2 below, and the method includes:

[0047] Step 201: In response to the target cell searched by the terminal device on the target frequency point during the cell residence process, establish an initial time synchronization between the terminal device and the target cell to be resident.

[0048] Exemplarily, as shown in Figure 3 below, Figure 3 101 in it may be a 4G network, 102 may be a base station, and 103 may be a terminal device. 3GPP (3rd Generation Partnership Project) describes the process of UE cell residence in TS36.331 and TS36304. During the UE network search process, when a cell is found on a frequency point and synchronization is obtained, the system message of the cell is read, the MIB and SIB1 are read. After reading SIB1, the UE will perform a residence check according to the residence information in SIB1. Only after the check is successful can the UE

[0049] reside in the target cell.

[0050] In the current cell residence check of the 3GPP protocol, the frequency point information selected by the current cell is compared with the freqBandIndicator or MultiBandInfoList in SIB1. If the current frequency point is included in the BAND (frequency band) corresponding to the freqBandIndicator or MultiBandInfoList, the UE can reside. If the current frequency point is not in the BAND indicated by the freqBandIndicator and MultiBandInfoList, then the UE cannot reside in this cell and will continue to search for cells on other frequency points and attempt to reside.

[0051] In some examples, according to the division of E-UTRA frequency bands in TS36.101, there may be overlapping situations between frequency bands, and cells can be deployed in the overlapping areas.

[0052] Exemplarily, as shown in Figure 4As shown, CELL1 belongs to BAND2 and does not belong to BAND1. In the network selection process specified by 3GPP, the UE first searches for BAND1. When CELL1 is detected and its bandIndicator is found to be BAND2, it is considered non-resident. Then, the UE initiates a search for BAND2 and discovers CELL1 again, at which point it can finally reside on it. In this scenario, since FREQ_1 and FREQ_2 have the same frequency, CELL1 will be found when searching for FREQ_1 during network search. During the process of attempting to reside, CELL1 could have resided when searching for BAND1, but actually completed the residence when searching for BAND2. During this period, additional time resources and computing resources were consumed. Also, since the UE did not reside in the cell, normal services could not be carried out, which also degraded the user experience.

[0053] For example, when the terminal device A is powered on or enters a new coverage area, it will search for available frequency points and cells. If the target frequency point 1 in cell 1 is found, it is necessary to detect the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) of cell 1 to achieve time synchronization and determine the physical layer ID of the cell.

[0054] In the embodiments of the present application, the Physical Layer Cell ID (PL-Cell ID) of a cell is an important parameter used to uniquely identify the cell and help the User Equipment (UE) perform initial time synchronization and cell selection when accessing the network.

[0055] In some examples, the Primary Synchronization Signal is one of the key signals for the UE to perform cell search and time synchronization. The PSS helps the UE quickly achieve time synchronization and determine the ID within the physical layer ID group of the cell. Specifically, the PSS helps the UE achieve time synchronization with the cell, and the PSS transmits the ID information within the physical layer ID group of the cell, which is part of the physical layer ID.

[0056] Correspondingly, the Secondary Synchronization Signal SSS is one of the key signals for the User Equipment UE to perform cell search and time synchronization. The SSS helps the UE determine the ID outside the physical layer ID group of the cell and achieve wireless frame synchronization. Specifically, the SSS transmits the ID information outside the physical layer ID group of the cell, which is part of the physical layer ID. The SSS helps the UE achieve wireless frame synchronization, that is, determine the boundary of the wireless frame.

[0057] Step 202: Read the MIB transmitted in the PBCH by the base station corresponding to the cell to be resided in, and determine the target frequency band information corresponding to the cell to be resided in based on the MIB.

[0058] Optionally, step 202 may specifically include: reading the MIB transmitted in the PBCH by the base station, decoding SIB1 in BCCH_DL_SCH based on the MIB; determining the target frequency band information corresponding to the cell to be camped on based on SIB1.

[0059] In the embodiments of the present application, the Physical Broadcast Channel (PBCH) is a key physical channel for transmitting the Master Information Block (MIB), which is the basic system information obtained by the UE when accessing the network. Specifically, the PBCH is used to transmit the MIB, which is the most basic information that the UE needs to obtain when first accessing the network. Although the PBCH itself does not directly provide time synchronization information, it is the first physical channel received after the UE completes time synchronization.

[0060] Furthermore, the MIB usually contains the following information: downlink bandwidth information (dl-bandwidth), the lower 10 bits of the system frame number (systemFrameNumber, SFN), and the configuration information of the Physical Hybrid ARQ Indicator Channel (PHICH).

[0061] In some examples, SIB1 is one of the key system information obtained by the UE during the network access process. SIB1 contains the necessary information required for the UE to perform preliminary cell selection and access. Specifically, SIB1 provides the configuration information related to cell access, including access control information, frequency information, etc. SIB1 contains the information on how to obtain other SIBs, which is crucial for the UE to further obtain other system information.

[0062] Furthermore, SIB1 usually contains cell access control information (accessControlInfo) including whether the cell allows access, access restrictions, etc.; the frequency band indicator (freqBandIndicator) is used to indicate the frequency band where the current cell is located. multiBandInfoList: contains the detailed configuration information of multiple frequency bands, including the center frequency, bandwidth, duplex mode, etc. of the frequency band. schedulingInfoList: the scheduling information of other SIBs, including the transmission period, scheduling information, etc. of the SIBs.

[0063] Exemplarily, based on step 201, after the UE establishes initial synchronization with cell 1, it detects the PSS, obtains an ID (one of 0, 1, 2) within the physical layer ID group, and then further detects the SSS to obtain an ID (one of 0 to 167) outside the physical layer ID group. The physical layer ID of cell 1 can be calculated through Formula 1 shown below:

[0064] Physical layer ID = Physical layer ID + 3 × ID outside the physical layer ID group (Formula 1)

[0065] Furthermore, the UE reads the MIB information in the PBCH according to the physical layer ID to obtain basic information such as the system frame number and downlink bandwidth, and then reads SIB1 in BCCH_DL_SCH according to the information in the MIB to obtain cell access-related information and scheduling information of other SIBs.

[0066] It should be noted that the target frequency band information may include freqBandIndicator and MultiBandInfoList in SIB1.

[0067] Step 203: If it is determined that the target frequency band information does not contain the target frequency point, convert the target frequency point into a dwellable frequency point.

[0068] Among them, the dwellable frequency point is used for the terminal device to dwell in the cell to be dwelled.

[0069] Optionally, step 203 may specifically include: if it is determined that the target frequency band information does not contain the target frequency point, obtain all the frequency band information included in SIB1, determine multiple candidate frequency bands supported by the terminal device from all the frequency band information; select a dwellable frequency band from the multiple candidate frequency bands, and convert the target frequency point into a dwellable frequency point included in the dwellable frequency band.

[0070] Among them, the dwellable frequency band is a frequency band that contains the target frequency corresponding to the target frequency point among the multiple candidate frequency bands.

[0071] Exemplarily, based on step 202, when the target frequency band information read by terminal device A does not contain target frequency point 1, it is necessary to read all the frequency band information in SIB1, select the frequency bands supported by terminal device A from all the frequency band information, and determine them as candidate frequency bands.

[0072] For example, if the frequency bands supported by the UE are Band 39 and Band 7, and the UE obtains the following information from SIB1: 1. Parse SIB1: freqBandIndicator: [3, 7, 39] · multiBandInfoList: Information of Band 3 (not considered as the UE does not support Band 3) · Information of Band 7 · Information of Band 39 2. Filter the frequency bands supported by the UE: · Screen out the frequency bands supported by the UE from the freqBandIndicator list: [7, 39] 3. Obtain frequency information: · Extract the detailed configuration information of Band 7 and Band 39 from the multiBandInfoList, for example: · Band 7: Center frequency is 2600 MHz, bandwidth is 20 MHz · Band 39: Center frequency is 1900 MHz, bandwidth is 10 MHz.

[0073] Optionally, step 203 specifically further includes: determining, in the preset order of multiple candidate frequency bands included in all frequency band information, multiple candidate frequency ranges corresponding to the multiple candidate frequency bands respectively; and when it is determined that the target frequency range among the multiple candidate frequency ranges contains the target frequency, determining the candidate frequency band corresponding to the target frequency range as the dwellable frequency band.

[0074] For this embodiment, different frequency bands correspond to specific frequency ranges. These frequency bands are defined and managed to ensure effective coordination and non-interference between different services.

[0075] Exemplarily, for the GSM system GSM 900: Uplink (MS→BS): 890 MHz to 915 MHz Downlink (BS→MS): 935 MHz to 960 MHz

[0076] GSM 1800: Uplink (MS→BS): 1710 MHz to 1785 MHz

[0077] Downlink (BS→MS): 1805 MHz to 1880 MHz

[0078] It should be noted that different frequency bands correspond to specific frequency ranges, and these frequency bands are allocated to different mobile communication technologies and services. By reasonably allocating and managing frequency bands, the limited spectrum resources can be effectively utilized to ensure the efficient operation of the mobile communication network.

[0079] Exemplarily, when determining multiple candidate frequency ranges corresponding to multiple candidate frequency bands respectively, and when it is determined that the target frequency range corresponding to the target frequency band among the multiple candidate frequency bands contains the frequency corresponding to the target frequency point, the target frequency band is determined as the dwellable frequency band.

[0080] It should be noted that the dwellable frequency band is the frequency band on which the terminal device can dwell through the target frequency point.

[0081] Optionally, step 203 specifically further includes: determining the transfer start frequency corresponding to the available residence frequency band and the transfer start frequency in the transfer frequency range, as well as the target start frequency in the target frequency range where the target frequency point is located; and converting the target frequency point into an available residence frequency point included in the available residence frequency band according to the target start frequency, the target start frequency point, and the target start frequency.

[0082] In the embodiment of the present application, after determining the available residence frequency band, the converted available residence frequency point can be obtained through Formula 1, and Formula 2 is specifically as follows:

[0083] Target frequency point = Frequency of the start frequency point - Start frequency of the selected Band + Start frequency point of the selected Band

[0084] (Formula 2)

[0085] It should be noted that in Formula 2, the target frequency point is the available residence frequency point in the present application, the frequency of the start frequency point is the start frequency of the target frequency point in the present application, the start frequency of the selected BAND is the start frequency of the available residence frequency band in the present application, and the start frequency point of the selected BAND is the target frequency point in the present application.

[0086] Compared with the current existing technologies, in this embodiment, when it is determined that the target frequency point is not included in the target frequency band information, for a cell with a mismatched BAND, frequency conversion is performed to convert the target frequency point into an available residence frequency point. Specifically, the original frequency point obtained by network search can be converted into a frequency point supported by the BAND. The terminal device then resides through the available residence frequency point, which can effectively reduce the consumption of time resources and computing resources brought by network selection, enable the terminal device to quickly reside in the cell, conduct normal services, and improve the user experience.

[0087] To illustrate the specific implementation process of this embodiment, the following specific application example is given, as Figure 5 shown, but not limited to this:

[0088] During the process of the UE residing in the cell, first, it searches for the cell on the corresponding frequency point and obtains initial synchronization for the cell; after obtaining the initial synchronization, the UE detects the BCCH channel, attempts to read the MIB, obtains frame information, and frame synchronization information; then it further detects the BCCH_DL_SCH channel and attempts to obtain SIB1 to obtain the residence verification information, including frequency band information (freqBandIndicator and MultiBandInfoList).

[0089] Compare whether the frequency point of the cell is in the BAND indicated by SIB1. If the BAND information check fails, try to perform the frequency band conversion algorithm. Calculate the corresponding frequency through the frequency point, and then convert it to the corresponding BAND. If the conversion to the corresponding BAND is successful, then the cell can be camped on.

[0090] Among them, as Figure 6 shown, after the BAND check fails, try to perform BAND conversion on the frequency point of the target cell, and convert the corresponding frequency point to the corresponding BAND.

[0091] The specific conversion content can include: filtering all BAND information (freqBandIndicator and MultiBandInfoList) in the obtained SIB1 to filter out the BANDs supported by the UE, and obtaining the frequency information of the original frequency point; sequentially select the BAND to be converted, and obtain the starting frequency information, ending frequency information, starting frequency point information, and ending frequency point information of the BAND.

[0092] If the frequency of the original frequency point is within the frequency range of the BAND to be converted, then it can be converted. Otherwise, select the next BAND and re-execute the process; after successfully selecting the BAND, the conversion can be performed through Formula 2 to complete the conversion process.

[0093] Compared with the current existing technologies, in this embodiment, when it is determined that the target frequency band information does not include the target frequency point, for a cell with a BAND mismatch, frequency conversion is performed to convert the target frequency point into a campable frequency point. Specifically, the original frequency point obtained by network search can be converted into a frequency point supported by the BAND, and the terminal device can then camp on the cell through the campable frequency point, which can effectively reduce the consumption of time resources and computing resources brought by network selection, enable the terminal device to quickly camp on the cell, perform normal services, and improve the user experience.

[0094] Further, as Figure 1 and Figure 2 shown in the specific implementation of the method, this embodiment provides a communication device, as Figure 7 shown, the device includes: an acquisition module 31 and a conversion module 32.

[0095] The acquisition module 31 is configured to obtain the target frequency band information corresponding to the cell to be camped on in response to the terminal device searching for the cell to be camped on through the target frequency point during the cell camping process.

[0096] A conversion module 32, configured to convert the target frequency point into a dwellable frequency point if it is determined that the target frequency band information does not include the target frequency point, where the dwellable frequency point is used for the terminal device to dwell in the to-be-dwelled cell.

[0097] In some examples of this embodiment, the acquisition module 31 is specifically configured to establish an initial time synchronization between the terminal device and the to-be-dwelled cell; read a master system information block MIB transmitted by a base station corresponding to the to-be-dwelled cell in a physical broadcast channel PBCH, and determine target frequency band information corresponding to the to-be-dwelled cell based on the MIB.

[0098] In some examples of this embodiment, the acquisition module 31 is further specifically configured to read the MIB transmitted by the base station in the PBCH, and decode a system information block SIB1 in BCCH_DL_SCH based on the MIB; determine target frequency band information corresponding to the to-be-dwelled cell based on the SIB1.

[0099] In some examples of this embodiment, the conversion module 32 is specifically configured to, if it is determined that the target frequency band information does not include the target frequency point, obtain all frequency band information included in the SIB1, determine multiple candidate frequency bands supported by the terminal device from the all frequency band information; select a dwellable frequency band from the multiple candidate frequency bands, and convert the target frequency point into a dwellable frequency point included in the dwellable frequency band, where the dwellable frequency band is a frequency band among the multiple candidate frequency bands that includes a target frequency corresponding to the target frequency point.

[0100] In some examples of this embodiment, the conversion module 32 is further specifically configured to sequentially determine multiple candidate frequency ranges corresponding to the multiple candidate frequency bands according to a preset order of the multiple candidate frequency bands included in the all frequency band information; and determine the candidate frequency band corresponding to the target frequency range as the dwellable frequency band when it is determined that a target frequency range among the multiple candidate frequency ranges includes the target frequency.

[0101] In some examples of this embodiment, the conversion module 32 is further specifically configured to determine a transfer start frequency point corresponding to the dwellable frequency band and a transfer start frequency in a transfer frequency range, and a target start frequency in a target frequency range where the target frequency point is located; and convert the target frequency point into a dwellable frequency point included in the dwellable frequency band according to the target start frequency, the target start frequency point, and the target start frequency.
