[0047] Hereinafter, embodiments of the present application will be described in more detail with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0048] In order to improve the technical problem that the current terminal is interfered by signals when accessing the LTE network in the GSM / LTE shared spectrum network. This embodiment provides a communication method, as Figure 1 shown, the method includes:

[0049] Step 101, determine that the cell accessed by the terminal is a cell sharing GSM spectrum and LTE spectrum.

[0050] For the execution subject of this embodiment, it may be a communication device or a communication device, and may be configured on the terminal device side, such as an electronic device or a chip, etc.

[0051] In some examples, the terminal device may be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device may also be an automobile with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, 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 may also be a chip or a chip system, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0052] The terminal may receive a GSM signal sent by a network device of GSM or may receive an LTE signal sent by a network device of LTE.

[0053] In one embodiment of the present application, the network device may be a device such as a base station or a satellite. In the embodiments of the present application, there is no specific limitation on the network device. The network device may be an entity on the network side for transmitting or receiving signals. For example, the network device may be a communication satellite, an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. Embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the network device. The network device provided by the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0054] In some examples, GSM belongs to the second-generation (2nd Generation, 2G) cellular mobile communication technology. Both the signaling and voice channels are digital, and it is the most widely used mobile phone standard currently. LTE is the long-term evolution of the Universal Mobile Telecommunications System (UMTS) technical standard formulated by the 3rd Generation Partnership Project (3GPP). It introduces key transmission technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multi-Input&Multi-Output (MIMO), significantly increasing the spectral efficiency and data transmission rate, and supporting various bandwidth allocations, such as 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz, etc., and supporting the mainstream 2G / 3G frequency bands globally and some new frequency bands. Therefore, the spectrum allocation is more flexible, and the system capacity and coverage are also significantly improved.

[0055] Step 102: Obtain GSM frequency point information.

[0056] In some examples, a frequency point is a number assigned to a fixed frequency. For example, if the frequency interval is 200 KHz, 125 wireless frequency bands can be divided from 890 MHz, 890.2 MHz, 890.4 MHz, 890.6 MHz, 890.8 MHz, 891 MHz... 915 MHz according to the frequency interval of 200 KHz, and each frequency band is numbered from 1, 2, 3, 4... 125. These numbers assigned to the fixed frequencies are the frequency points. In the GSM network, frequency points can be used to replace frequencies to specify the transmission frequencies of transceiver units.

[0057] For this embodiment, multiple optional methods can be used to obtain GSM frequency point information. For example, the power spectral density method, the frequency point search method based on RSSI (Received Signal Strength Indicator), the frequency sweep measurement method, etc. Exemplarily, as an optional method, GSM frequency points can be scanned through the power spectral density (PSD) method. Among them, the power spectral density method is a probability and statistics method, which is a measure of the mean square value of a random variable and can show the variation of signal power in a unit frequency band with the frequency band. Specifically, for each frequency point to be scanned within the scanning interval, the number of sample points satisfying one sub-frame is collected. The sample points of one sub-frame are divided into n segments, the power spectral density of each segment of the signal is calculated, and then the eigenvalue of each segment is obtained based on the power spectral density of each segment, and the maximum eigenvalue in this sub-frame is retained. The eigenvalues of each frequency point within the entire scanning interval form an eigenvalue list, and the GSM frequency points are obtained based on the eigenvalues in this eigenvalue list.

[0058] Step 103: Perform filtering processing on the GSM frequency point information through a radio frequency filter.

[0059] As Figure 2 shown, the mobile communication module of current smart phones can include: an antenna, radio frequency, baseband / application processor, etc. Among them, the radio frequency includes a transceiver and a radio frequency front end, and the radio frequency front end includes a switch, a filter, a power amplifier, and a low-noise amplifier connected to the antenna.

[0060] For example, in the GSM and LTE shared spectrum network configuration, if the GSM frequency points fall within the LTE frequency range, when the terminal accesses the LTE network, it uses the bandwidth configuration issued by the network and selects standard 5M / 10M / 15M / 20M filter bandwidths to filter the signals received by the antenna. However, these filters with standard bandwidths fail to filter out the GSM frequency points, resulting in GSM interference signals being included in the LTE signals, interfering with the demodulation of the LTE signals and affecting the demodulation performance of the terminal in the LTE network.

[0061] Exemplarily, as Figure 3As shown, in order to take into account the user equipment of the GSM network, the operator can improve the utilization efficiency of the low-frequency band (such as GSM900M) network through spectrum sharing. For example, a 2.4M bandwidth GSM network and a 10M bandwidth LTE network are deployed using 10.8M bandwidth in the GSM900M band. Among them, the LTE independently uses 8.4M bandwidth and shares 1.6M bandwidth with the GSM. When the end user accesses the LTE, since the LTE bandwidth configured and distributed by the LTE network is 10M, the terminal selects a 10M RF filter, resulting in the GSM signal falling within the filter range, interfering with the LTE signal, affecting the demodulation performance of the LTE terminal, and affecting the user experience.

[0062] In the embodiment of the present disclosure, by filtering this part of the GSM frequency point information through a radio frequency filter, the interference can be reduced when the terminal accesses the LTE network under the GSM and LTE shared spectrum network, ensuring the signal quality when the user terminal accesses the LTE network.

[0063] Compared with the current existing technologies, in this embodiment, first, it is determined that the cell accessed by the terminal is a cell sharing the GSM spectrum and the LTE spectrum; then, the GSM frequency point information is obtained; and then, the GSM frequency point information is filtered through a radio frequency filter. In this embodiment, under the GSM and LTE shared spectrum network configuration, when the terminal accesses the LTE network, by filtering the corresponding GSM frequency point information, the interference of the GSM signal on the LTE signal is reduced, the influence on the demodulation of the LTE signal is reduced, and further, the demodulation performance of the terminal when accessing the LTE network is optimized, and the user experience is improved.

[0064] Furthermore, in order to illustrate the specific implementation process of the method in this embodiment, this embodiment provides a specific method as shown in Figure 4 which includes:

[0065] Step 201: Determine that the cell accessed by the terminal is an LTE cell in the target band.

[0066] In the embodiment of the present disclosure, the target band is a band configured with shared GSM and LTE spectra.

[0067] Step 202: Detect whether the scanned GSM frequency points fall within the target band.

[0068] In some examples, if it is determined that the cell the terminal is about to access is an LTE cell in the target band, where the target band can be the GSM900M band, then check whether the scanned GSM frequency points fall within the LTE cell band.

[0069] Optionally, obtain the power spectral density of the target frequency band; filter out the LTE signals in the target frequency band according to the power spectral density; in response to the presence of signal spikes, receive GSM system messages based on the target frequency points corresponding to the signal spikes; in the case where the GSM system messages can be correctly parsed, determine that the scanned GSM frequency points fall within the target frequency band.

[0070] As Figure 5 shown, the power spectral density of GSM is much higher than that of LTE, that is, in the power spectral density on a specific spectrum, GSM signals appear as spikes. Exemplarily, use radio frequency (RF) to scan the GSM900M frequency band of the target cell to obtain the power spectral density of this frequency band. Among them, the bandwidth of each GSM signal is 200k, Figure 5 and there are 4 GSM signals overlapping on both sides of the LTE frequency band, that is, GSM and LTE share the frequency band.

[0071] Exemplarily, filter out the LTE signals in the frequency band shared by GSM and LTE as the background noise. If there are signal spikes, there are GSM signals or interference signals. Use this signal spike as the GSM frequency point to receive GSM system messages. If the basic elements such as the header mark, protocol identifier, timestamp, and user data of the GSM system messages can be correctly parsed according to the message element table, it means that the GSM system messages can be correctly parsed, then this frequency point is the GSM frequency point.

[0072] Optionally, in the case where the GSM system messages cannot be correctly parsed, determine that the signal corresponding to the signal spike is an interference signal.

[0073] Step 203: If the scanned GSM frequency points fall within the target frequency band, determine that the cell accessed by the terminal is a cell sharing GSM spectrum and LTE spectrum.

[0074] Step 204: Obtain GSM frequency point information.

[0075] Optionally, in the case where the GSM system messages can be correctly parsed, determine the target frequency points as GSM frequency points, and count the GSM frequency points and the number thereof as GSM frequency point information.

[0076] In the embodiments of the present disclosure, for a cell sharing GSM spectrum and LTE spectrum, the GSM frequency points and the number thereof can be calculated by the method in step 202, and the specific method will not be elaborated here. And notify the actual LTE network usage bandwidth to the RF filter.

[0077] Step 205: Perform filtering processing on the GSM frequency point information through the RF filter.

[0078] Optionally, filter out the GSM frequency points by controlling the RF filter to shrink the filtering bandwidth.

[0079] Exemplarily, as Figure 6 shown, the cell is configured with an LTE network of 10M bandwidth, and 4 GSM frequency points are configured on both sides of the LTE network. Each GSM signal has a bandwidth of 200k, that is, a total of 1.6M bandwidth of LTE is occupied. The radio frequency filter receives the actual used bandwidth of the LTE cell from the baseband as 8.4M. Controlling the radio frequency filter to adjust the filtering bandwidth from 10M to 8.4M can complete the filtering.

[0080] Optionally, after filtering out the GSM frequency points by controlling the radio frequency filter to contract the filtering bandwidth as described above, it specifically further includes: when it is determined that the cell accessed by the terminal is not a cell sharing GSM spectrum and LTE spectrum, controlling the radio frequency filter to restore the filtering bandwidth.

[0081] In some examples, as Figure 7 shown, when the user accesses other cells sharing non-GSM spectrum and LTE spectrum, the baseband notifies the radio frequency filter to restore the filtering bandwidth.

[0082] Optionally, the radio frequency filter is a broadband filter with adjustable filtering range, or the radio frequency filter is composed of multiple narrowband filters.

[0083] For example, the radio frequency filter can consider using a broadband filter whose filtering range can be adjusted between 0M and 20M, or 100 narrowband filters with a bandwidth of 200k to form the 20M filtering bandwidth required for the LTE network.

[0084] Compared with the current existing technologies, in the network configuration of sharing GSM and LTE spectrums, when the terminal accesses the LTE network, the configuration of this solution can filter out the corresponding GSM frequency point information by controlling the radio frequency filter to contract the filtering bandwidth, reducing the interference when the terminal accesses the LTE in the GSM and LTE shared spectrum network, optimizing the demodulation performance of the terminal when accessing LTE, and improving the user experience.

[0085] Furthermore, as a Figure 1 and Figure 4 specific implementation of the method shown, this embodiment provides a communication device, as Figure 8 shown, the device includes: a determination module 31, an acquisition module 32, and a processing module 33.

[0086] The determination module 31 is configured to determine that the cell accessed by the terminal is a cell sharing GSM spectrum and LTE spectrum;

[0087] The acquisition module 32 is configured to acquire GSM frequency point information;

[0088] The processing module 33 is configured to filter the GSM frequency point information through a radio frequency filter.

[0089] In some examples of this embodiment, the determination module 31 is specifically configured to determine that the cell accessed by the terminal is an LTE cell in the target frequency band; detect whether the scanned GSM frequency point falls within the target frequency band; if the scanned GSM frequency point falls within the target frequency band, determine that the cell accessed by the terminal is a GSM spectrum and LTE spectrum sharing cell.

[0090] In some examples of this embodiment, the determination module 31 is further specifically configured to obtain the power spectral density of the target frequency band; filter the LTE signal in the target frequency band as the background noise according to the power spectral density; in response to the presence of a signal spike, receive the GSM system message based on the target frequency point corresponding to the signal spike; and determine that the scanned GSM frequency point falls within the target frequency band when the GSM system message can be correctly parsed.

[0091] In some examples of this embodiment, the acquisition module 32 is specifically configured to determine that the target frequency point is a GSM frequency point when the GSM system message can be correctly parsed, and count the GSM frequency point and the number thereof as the GSM frequency point information.

[0092] In some examples of this embodiment, the determination module 31 is further specifically configured to determine that the signal corresponding to the signal spike is an interference signal when the GSM system message cannot be correctly parsed.

[0093] In some examples of this embodiment, the processing module 33 is specifically configured to filter the GSM frequency points by controlling the radio frequency filter to shrink the filter bandwidth.

[0094] In some examples of this embodiment, the processing module 33 is further specifically configured to, after filtering the GSM frequency points by controlling the radio frequency filter to shrink the filter bandwidth, control the radio frequency filter to restore the filter bandwidth when it is determined that the cell accessed by the terminal is not a GSM spectrum and LTE spectrum sharing cell.

[0095] In some examples of this embodiment, the processing module 33 is further specifically configured that the radio frequency filter is a broadband filter with an adjustable filtering range, or the radio frequency filter is composed of a plurality of narrowband filters.
