Description

Cell search method and user equipment

Technical Field

The present disclosure relates to the field of mobile communications technologies, and in particular, to a cell search method and a user equipment.

Background

With the evolution and commercial use of the fifth generation (5th generation, 5G) mobile communication technology, there are two networking modes of a Non-independent (NSA) architecture and an independent (SA) architecture on the network side.

The SA architecture belongs to a network architecture of independent 5G carriers and does not depend on Long Term Evolution (LTE) carriers.

The NSA architecture is a new type of carrier (5G carrier) added on the basis of LTE, and the carrier can be used for carrying data services. Thus, NSA is an intermediate product of 5G network evolution relative to a well-established SA networking architecture. In the NSA architecture, a User Equipment (UE) may register to an LTE network, and the LTE network may add a New Radio (NR) cell to the UE. The NR cell may also be referred to as a 5G cell. In order to reduce the power consumption of the ue, when the current data traffic of the ue does not reach a threshold (the LTE network can meet the current service requirement of the ue) or the ue has no data service, the network side may instruct the ue to enter an idle state (idle), and release the NR cell. After the user equipment releases the NR cell, when the network side determines that the data volume of the user equipment performing the data service again meets the condition of adding the NR cell, the network side can add the NR cell for the user equipment again to ensure the smoothness of the data service.

In some scenarios, it is necessary to detect signals of a mobile communication network (e.g., a 5G network, a 4G network, etc.) in an environment where the mobile communication network is located, so as to select a place where the signals of the mobile communication network are better for surfing the internet. For example, when placing a mobile wireless fidelity (Wi-Fi) device, a user usually needs to select a place with better mobile communication network signal so as to improve the internet speed. The mobile Wi-Fi device is a router which is accessed to a mobile communication network through a Subscriber Identity Module (SIM) card, and the router can be used as a hot spot to provide Wi-Fi signal coverage, so that a terminal can be accessed to the mobile communication network through the router.

Under the SA architecture, an application processor of the user equipment may issue AT commands to the modem when evaluating mobile communication network signals in the environment. The modem measures a Reference Signal Receiving Power (RSRP) and a signal to interference plus noise ratio (SINR) of a cell in which the user equipment currently resides in response to the AT command. And converting the measured RSRP and SINR through a certain algorithm to obtain the signal quality of the current resident cell.

Under the NSA architecture, since whether the user equipment accesses the NR cell depends on the data volume of the data service of the user equipment, the data volume of the current data service of the current user equipment is small, and the network side releases the NR cell to which the user equipment accesses. In this case, the user equipment can only perceive the signal quality of the LTE cell, but cannot directly perceive the signal quality of the NR cell. Therefore, in this case, how to accurately evaluate the signal quality of the NR cell directly affects the accuracy of the mobile communication network quality evaluation result in the environment.

Detailed Description

The technical solution in the embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments.

Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise.

Wherein in the description of the present specification, "/" indicates a meaning, for example, a/B may indicate a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present specification, "a plurality" means two or more.

In the description of the present specification, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

Under the NSA architecture, the user equipment may camp on an LTE cell. If the data volume of the data service of the user equipment is large, the network side can add an NR cell to the user equipment, so that the user equipment can be simultaneously accessed to an LTE cell and the NR cell. If the user equipment does not perform the data service or the data volume of the data service is small, the network side can instruct the user equipment to release the NR cell.

For the case where the user equipment does not access the NR cell, the scheme of evaluating the mobile communication network quality in the environment may be as follows.

In the first scheme, when the user equipment evaluates the quality of the mobile communication network in the environment, the signal quality of the NR cell in the environment is not considered, but evaluated based on the signal quality of the LTE cell in which the user equipment currently resides. In this scheme, the signal quality of the NR cells in the environment is not considered, so that there is a large error in the evaluation result and the true situation. Specifically, in the same location and the same network environment, the difference between the signal quality evaluation result when accessing the NR cell (where the data volume of the data service of the user equipment is large and the NR cell is added to the user equipment by the trigger network side) and the signal quality evaluation result when not accessing the NR cell (where the user equipment does not have the data service or the data service is not large enough) is large.

In the second technical solution, the ue is in an idle state, the application layer issues a ^ NETSCAN instruction (for example, AT ^ NETSCAN ^ 1, XX, 3) to the communication protocol layer, triggers the communication protocol layer to perform a round of NR full band (band) network search (in the network search process, the ue continues to camp in an LTE cell), and reports the signal quality parameters (for example, RSRP, SINR) of the NR cell whose signal strength is greater than a threshold (XX dbm) and is the maximum to the application layer. And the application layer uses the reported signal quality parameters to combine with the signal quality of the current resident LTE cell to comprehensively calculate the quality score of the mobile communication network in the environment. This solution has the following problems.

In the scheme, each time the quality of the NR signal is searched in the case of residing in the LTE cell, all frequency bands and cells on the frequency bands of the NR should be scanned comprehensively, which takes long time and is poor in user experience.

In the scheme, a signal quality parameter of an NR cell having a maximum signal strength and a signal strength greater than a threshold is reported to an application layer, where the NR cell may be a cell to which a SIM card of a user equipment cannot register, that is, the NR cell may be a cell in a Forbidden Public Land Mobile Network (FPLMN) of the SIM card of the user equipment. For example, the SIM card belongs to an operator a1, and the NR cell corresponding to the reported signal quality parameter is a cell of an operator a 2.

C, the future 5G product form may include Customer Premise Equipment (CPE), mobile Wi-Fi (mobile Wi-Fi) equipment, a mobile phone, a vehicle module, and other user equipment. An operator can divide a dedicated frequency band and a standby frequency band for different product forms so as to improve the utilization rate of the frequency bands; and when the exclusive frequency band does not meet the network injection condition, the user equipment can be switched to the standby frequency band for temporary use. In other words, the dedicated band has a high priority over the spare band. For example, the NR frequency band includes three frequency bands N41, N77, and N78, and the operator a1 divides N41 into CPEs as dedicated frequency bands and divides N77 and N78 into CPEs as spare frequency bands. When the SIM card of the CPE registers the network, the CPE, according to the specification of the operator a1, will preferentially search whether the cell to which the dedicated frequency band belongs meets the residence condition, and if not, will search the cell to which the standby frequency band belongs. In the second scheme, the NR cell corresponding to the reported signal quality parameter has the largest signal strength among all the NR frequency bands, and the cell with the largest signal strength does not necessarily belong to the dedicated frequency band. In other words, the user equipment is not necessarily camped in the cell with the highest signal strength when it is the primary network. Therefore, in the second scheme, the evaluation result of the NR network quality in the environment cannot reflect the signal quality of the NR cell to which the user equipment is actually registered.

The embodiment of the specification provides a cell search method, which can be applied to user equipment configured with an application processor and a modem. In the method, the application processor can send a network searching instruction to the modem; in response to the network searching instruction, the modem can preferentially search cells on an exclusive frequency band and/or historical frequency points; when at least one cell in the cells on the dedicated frequency band and/or the historical frequency point meets the reporting condition, the modem can send the signal quality parameters of the at least one cell to the application processor; the application processor may determine the network quality in the environment where the user equipment is currently located according to the signal quality parameter of the at least one cell.

Fig. 1 illustrates a network architecture to which the cell search method provided in the embodiments of the present specification is applicable. The network architecture includes a user equipment 100, a primary network node (MN) 210, a secondary network node (SN) 220, and a core network (core network) 230. The Dual Connectivity (DC) capability supported by the user equipment 100 matches the dual connectivity capability supported by the main network node 210. The user equipment 100 may establish a connection with the primary network node 210 and the secondary network node 220, respectively.

In this specification embodiment, the main network node 210 may be an evolved node B (eNB) in an LTE system. The secondary network node 220 may be a next generation base station (gNB) in a 5G system, a new air interface (NR) system. The primary functions of the primary network node 210 and the secondary network node 220 include: management of radio resources, compression of Internet Protocol (IP) headers and encryption of user data streams, selection of Mobility Management Entity (MME) when a user equipment is attached, routing of user plane data to Serving Gateway (SGW), organization and transmission of paging messages, organization and transmission of broadcast messages, measurement for mobility or scheduling, and configuration of measurement reports. In addition, primary network node 210 or secondary network node 220 may also be an Access Point (AP), a Central Unit (CU), or other network entity, and may include some or all of the functionality of the above network entities. The name "network node" may vary. Furthermore, the primary network node 210 and the secondary network node 220 may be other means providing wireless communication functionality for the user equipment 100, where possible. For convenience of description, in the embodiment of the present specification, an apparatus for providing a wireless communication function for the user equipment 100 is referred to as a network node.

For NSA networking, the third generation partnership project (3 GPP) version (release, R)15 defines a Dual Connectivity (DC) framework of Long Term Evolution (LTE) and New Radio (NR) including evolved universal terrestrial radio access network (E-UTRAN) -NR dual connectivity (E-UTRA-NR) architecture. In the early stage of 5G network deployment, most operators chose an EN-DC architecture as a networking mode of NSA. The EN-DC architecture does not need to add a fifth generation (5th generation, 5G) core network, only needs to add a 5G base station, cooperates with an existing fourth generation (4th generation, 4G) base station, and provides 5G +4G combined access for the user equipment, and when the user equipment is in an EN-DC state, the user equipment is simultaneously accessed to a 4G cell and a 5G cell, where the 4G cell may be referred to as a Master Cell Group (MCG), and the 5G cell may be referred to as a Secondary Cell Group (SCG).

Under the EN-DC architecture, the primary network node 210 may be an eNB and the secondary network node 220 may be a gNB. The core network to which the eNB and the gNB are connected may be a 4G core network (EPC). For example, in the wireless communication system shown in fig. 1 in particular, the primary network node 210 may be an eNB, the secondary network node 220 may be a gNB, and the core network 230 may be an EPC. Under the EN-DC architecture, the user equipment 100 may first register with a cell provided by the primary network node 210, i.e. a primary cell (also referred to as a 4G cell), and then the primary network node 210 determines whether a cooperative secondary cell exists in the primary cell where the user equipment 100 currently resides. The secondary cell, i.e. the cell provided by the secondary network node 220, may also be referred to as a 5G cell. When there is a cooperative secondary cell in the cell where the user equipment 100 currently resides, the master network node 210 queries whether the user equipment 100 supports EN-DC. When the user equipment 100 supports EN-DC, the primary network node 210 adds a secondary cell to the user equipment 100 through a secondary cell addition procedure. When the primary network node 210 adds a secondary cell to the user equipment 100, the user equipment 100 may be said to enter an EN-DC state.

The user device 100 may be a device for providing voice and/or data connectivity to a user. The device may be a handheld device or other processing device having wireless connection capability. The user equipment 100 may communicate with one or more core networks via a Radio Access Network (RAN). The user device 100 may be a cell phone, a tablet, a wearable device, a Personal Digital Assistant (PDA), a Customer Premises Equipment (CPE), a mobile Wi-Fi device, or the like.

The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system.

In some embodiments, at least some of the functional modules of the mobile communication module 150 may be disposed in the same device as at least some of the modules of the processor 110.

The modem processor may include a modulator and a demodulator. The modulator is used for modulating a low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then passes the demodulated low frequency baseband signal to a baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor. The application processor outputs a sound signal through an audio device (not limited to the speaker 170A, the receiver 170B, etc.) or displays an image or video through the display screen 194. In some embodiments, the modem processor may be a stand-alone device.

In the embodiments of the present specification, unless otherwise specified, the network refers to a mobile communication network, such as a 5G network, a 4G network, and the like.

Application is carried out.

Illustratively, as shown in FIG. 4A, the terminal device 400 may display an interface 420 as shown in FIG. 4B in response to a user-initiated operation with respect to an application 410.

Illustratively, the terminal device 400 may further display an interface 440 as shown in fig. 4D in response to a user-initiated operation directed to the function area 431, the interface 440 being used to prompt the user that the network quality of the mobile communication network is being evaluated. In one example, interface 440 may also include a functional area 441. When the terminal device 400 receives the operation for the functional area 441, an evaluation cancellation instruction may be sent to the user device so as to trigger the user device 100 to stop the network searching process.

In some embodiments, user device 100 may be a display-equipped device. The user equipment 100 may be installed with a network evaluation application (e.g., a wire speed test-type application). The network evaluation application may invoke relevant hardware (application processor, modem, etc.) of the user equipment 100 to perform a network searching procedure, and evaluate the network quality of the mobile communication network in the environment where the user equipment 100 is located.

Illustratively, as shown in fig. 5A, the wire speed test application 510 may be included in the application list of the user equipment 100. The user device 100 may implement an interface 520 as shown in fig. 5B in response to a user initiated operation directed to the wire speed test application 510. Interface 520 is a network assessment interface that may include a functional area 521. The functional area 521 may display a prompt message for prompting the user to perform mobile communication network evaluation, for example, the prompt message may be specifically "evaluate network quality of the mobile communication network". The user equipment 100 may receive an operation initiated by the user with respect to the functional zone 521, and in response to the operation, start a network searching procedure and evaluate the network quality of the mobile communication network in the environment in which the user equipment 100 is located. Among them, the operation initiated by the user for the function area 521 may be referred to as a network evaluation instruction.

Illustratively, the user equipment 100 may further display an interface 530 as shown in fig. 5C in response to a user-initiated operation directed to the functional area 5211, the interface 530 being used to prompt the user that the network quality of the mobile communication network is being evaluated. In one example, interface 530 may also include a functional area 531. When the user equipment 100 receives an operation for the functional region 531, the network searching procedure may be stopped.

Next, with continued reference to fig. 3, a web searching process is exemplified. It should be noted that the network searching process in the following description specifically refers to a network searching process of a 5G network.

As shown in fig. 3, when the user equipment 100 receives the network evaluation instruction, the user equipment 100 may execute step 302 to determine whether the network currently registered by the user equipment 100 belongs to the SA architecture. . The ue 100 may determine whether the currently registered network belongs to the SA architecture by determining the mode of the network.

When the network currently registered by the ue 100 belongs to the SA architecture, the ue 100 may perform step 303 to determine the network quality according to the signal quality parameter of the currently registered network. Reference may be made to the prior art specifically, and details are not repeated herein.

When the ue 100 is currently registered in a network other than the SA architecture, the ue 100 may execute step 304 to determine whether the ue 100 is in the EN-DC state. Illustratively, the user equipment 100 may determine whether the NR anchor cell of the camped LTE cell is active. If the NR anchor cell is active, the ue 100 is in an EN-DC state. If the NR anchor cell is not active, the user equipment 100 is not in the EN-DC state.

When the user equipment 100 is in the EN-DC state, the user equipment 100 may perform step 303.

When the ue 100 is not in the EN-DC state, the ue 100 may execute step 305 to determine whether the ue 100 is in an idle state (idle) in the LTE network.

For example, the user equipment 100 may determine whether the user equipment 100 is in an idle state in the LTE network by determining whether a Radio Resource Control (RRC) link exists between the user equipment 100 and an access network device (e.g., an eNB) of the LTE network.

It is understood that the user equipment 100 may establish an RRC link with the access network equipment of LTE through a random access procedure. In an example, taking a contention-based random access procedure as an example, the user equipment 100 may send a Random Access Preamble (RAP), i.e. a Message1, to the access network equipment of LTE; the access network device of LTE may feed back a Random Access Response (RAR) to the user equipment 100, i.e. Message 2; the user equipment 100 may send a contention resolution request, i.e., Message3, to the access network equipment of LTE; the access network device of LTE may send a contention resolution result, i.e., Message4, to the user equipment 100. Thereby, an RRC link between the user equipment 100 and the access network equipment of LTE may be established.

After the RRC link is established between the user equipment 100 and the access network device of the LTE, if the user equipment 100 receives an RRC connection release message from the access network device of the LTE, the RRC link is released, and the user equipment 100 enters an RRC idle state. If the user equipment 100 does not receive the RRC connection release message from the access network device of LTE, the RRC link between the user equipment 100 and the access network device of LTE continues to be maintained, and the user equipment 100 continues to be in the RRC connected state.

Therefore, the user equipment 100 may determine whether to be in an idle state in the LTE network according to whether to receive the RRC connection release message sent by the access network equipment of the LTE.

If the user equipment 100 does not receive the RRC connection release message sent by the access network device of LTE, it may be determined that the user equipment 100 is in the RRC connected state. In this case, the user equipment 100 may perform step 303.

If the user equipment 100 receives the RRC connection release message sent by the access network device of LTE, it may be determined that the user equipment 100 is in an idle state.

When the user equipment 100 is in the idle state, the user equipment 100 may execute step 306 to obtain the network searching instruction and the spectrum indication information.

In some embodiments, in step 306, the application processor of the user equipment 100 may issue a network searching instruction and spectrum indication information to the modem of the user equipment 100. That is, in this embodiment, the modem of the user equipment 100 may acquire the network searching instruction and the spectrum indication information from the application processor of the user equipment 100. Specifically, when the application processor of the user equipment 100 determines that the user equipment 100 is in the idle state, the network searching instruction and the spectrum indication information may be issued to the modem of the user equipment 100.

In some embodiments,

steps

302, 304, and 305 described above may be performed by a modem of user equipment 100. When the modem determines that the ue 100 is in the idle state in the LTE network in step 305, the modem may report a notification message to the application processor of the ue 100, where the notification message is used to notify the application processor that the ue 100 is in the idle state in the LTE network. When the application processor receives the notification message, the application processor may issue a network searching instruction and spectrum indication information to the modem.

The spectrum indication information is used to indicate a partial spectrum in the NR spectrum. For convenience of description, the frequency spectrum indicated by the frequency spectrum indication information may be referred to as a frequency spectrum D1. When the user equipment 100 registers for an NR cell, the user equipment 100 preferentially registers for a cell on spectrum D1. That is, the user equipment 100 is more preferentially registered to a cell on the spectrum D1 than to other spectra in the NR spectrum (spectra other than the spectrum D1). The network searching instruction is used for instructing the user equipment 100 (the modem of the user equipment 100) to perform network searching on the spectrum D1.

Next, a network searching instruction and spectrum indication information will be described as examples.

In some embodiments, the network searching instruction may include condition C1 and the number of cells n. Where n is a natural number, which represents the number of cells that the modem needs to report to the application processor. In the embodiments of the present specification, n may be 1, 2, 3, or the like, which are not listed. Condition C1 is a condition that needs to be met by the cell reported to the application processor. In other words, the network searching command including the conditions C1 and n is used to trigger the modem to perform network searching, screen out n cells satisfying the condition C1 from the network searching result, and report the n cells to the application processor. In one example, the condition C1 may be a signal strength threshold, and the cell satisfying the condition C1 refers to a cell having a signal strength greater than the signal strength threshold. In one example, the condition C1 may be an SINR threshold, and the cell satisfying the condition C1 refers to a cell whose SINR is greater than the SINR threshold. The scheme for reporting the cell to the application processor by the modem will be described in detail below, and will not be described herein again.

It should be noted that, as described above, in step 306, the application processor also issues spectrum indication information to the modem. In the embodiment of the present specification, the specific example of the modem performing network searching is that the modem performs network searching on the frequency spectrum indicated by the frequency spectrum indication information.

For example, the network searching command may be "AT Λ NETSCAN ═ n, XX". n is introduced in the above paragraph and will not be described in detail here. "XX" represents condition C1. For example, when condition C1 is a signal strength threshold, "XX" is specifically a signal strength threshold, which may be in units of dbm. For another example, when the condition C1 is an SINR threshold, "XX" is specifically an SINR threshold.

In some embodiments, the spectrum indication information may include a band list (bandlist) L1, the band list L1 includes at least one band identifier, and the corresponding band may be a dedicated band of the user equipment 100. That is, spectrum D1 may include frequency bands specific to user equipment 100.

Understandably, the product morphology of 5GMay include CPE, mobile Wi-Fi equipment, cell phones, in-vehicle modules, and other modalities. Operator A1 (e.g., see FIGS.)

Or

Etc.) different dedicated and backup frequency bands can be allocated for products of different forms. In one example, the NR band of operator a1 may be set to include three bands, i.e., band N41, band N77, and band N78. The operator a1 may divide the frequency band N41 into the CPE as a dedicated frequency band, and the frequency bands N77 and N78 are spare frequency bands of the CPE. That is, when the user equipment 100 is a CPE, the spectrum D1 may include a band N41. In another example, the carrier a1 may divide the frequency band N77 into the mobile phones as the dedicated frequency band, and the frequency bands N41 and N78 are the spare frequency bands of the mobile phones. That is, when the user equipment 100 is a mobile phone, the frequency band indicated by the spectrum indication information is N77. In yet another example, operator a1 may partition frequency band N78 to mobile Wi-Fi devices as a dedicated frequency band, and frequency bands N41 and N77 are spare frequency bands for mobile Wi-Fi devices. That is, when the user device 100 is a mobile Wi-Fi device, the spectrum D1 includes a band N78.

The above examples are merely illustrative and are not intended to be limiting. Different operators can divide the exclusive frequency band and the standby frequency band for different product forms according to respective requirements.

In some embodiments, the frequency band identification (e.g. the label of the frequency band) of the dedicated frequency band of the user equipment 100 may be pre-configured in the user equipment 100. In an example, one or more operators supported by the user equipment 100 may be set, and when the user equipment 100 leaves a factory, the frequency band identifier of the dedicated frequency band, which is divided for the product form to which the user equipment 100 belongs by the one or more operators, may be configured in the user equipment 100. In one example, the frequency band identification of the dedicated frequency band may be contained in a configuration file, which may be stored in a memory of the user equipment 100. When the application processor of the user equipment 100 needs to issue a network searching instruction to the modem of the user equipment 100, the application processor may retrieve the frequency band identifier of the dedicated frequency band from the memory, and list the frequency band identifier of the dedicated frequency band in the frequency band list L1 to obtain the spectrum indication information.

In some embodiments, the frequency band identifier of the dedicated frequency band of the user equipment 100 may be issued to the user equipment 100 by the network equipment. In an example, when the user equipment 100 is connected to the primary network node 210 (or the secondary network node 220), the primary network node 210 (or the secondary network node 220) may obtain a product form of the user equipment 100, and further may determine a dedicated frequency band divided by an operator to which the primary network node 210 (or the secondary network node 220) belongs for the product form to which the user equipment 100 belongs, and send a frequency band identifier of the dedicated frequency band to the user equipment 100. In one example, when the user equipment 100 receives the frequency band identifier of the dedicated frequency band, the frequency band identifier of the dedicated frequency band may be stored in the memory. When the application processor of the user equipment 100 needs to issue a network searching instruction to the modem of the user equipment 100, the application processor may retrieve the frequency band identifier of the dedicated frequency band from the memory, and list the frequency band identifier of the dedicated frequency band in the frequency band list L1 to obtain the spectrum indication information.

In some embodiments, the spectrum indication information may include frequency point identification (e.g., frequency point number or frequency point number) of the historical frequency points. The history frequency point is a frequency point where an NR cell that the user equipment 100 has accessed most recently is located. That is, the spectrum D1 may be a frequency point where an NR cell that is accessed by the user equipment 100 most recently is located. The NR cell that the user equipment 100 has recently accessed may also be referred to as an NR cell that the user equipment 100 has last accessed, specifically, an NR cell that is distant from the current time in the time dimension at the access time of the user equipment 100. It can be understood that, when attempting to access an NR cell, the user equipment 100 preferentially attempts to access a cell on a frequency point where an NR cell that was accessed last time is located. In other words, the priority of the cell on the frequency point where the NR cell that the user equipment 100 registers to is accessed last time is higher than the priority of the cell on the other NR frequency points where the user equipment 100 registers. Therefore, the signal quality parameter of the cell on the frequency point where the NR cell that the user equipment 100 has recently accessed is used to evaluate the NR network quality of the user equipment 100 in the environment where the user equipment 100 is located, so that the signal quality of the NR cell that the user equipment 100 accesses next time can be better reflected.

In some embodiments, the spectrum indication information may include both the frequency point identification of the historical frequency points and the frequency band list L1. That is, the spectrum D1 may include a combination of a frequency point where an NR cell historically accessed by the user equipment 100 is located and a dedicated frequency band of the user equipment 100.

Referring to fig. 3, the user equipment 100 may perform step 307 to perform a network search on the spectrum D1. Illustratively, step 307 may be specifically performed by a modem of the user equipment 100.

Searching for a network may also be referred to as cell search or cell measurement. The user equipment 100 may measure signal quality parameters of its detected or searched cells during the network searching process. The signal quality parameter may include any one or a combination of RSRP, SINR, Reference Signal Received Quality (RSRQ), and Received Signal Strength Indication (RSSI). The signal quality parameter of the cell searched on spectrum D1 may be used by the user equipment 100 to determine the NR signal quality in the environment in which the user equipment 100 is located. That is, the user equipment 100 may determine or evaluate the NR network quality in the environment in which the user equipment 100 is located according to the signal quality parameter of the cell searched on the spectrum D1.

Next, a specific scheme for determining the NR network quality in the environment where the user equipment 100 is located according to the signal quality parameter of the cell searched on the spectrum D1 will be described.

In some embodiments, the network search command may include condition C1 and the number of cells n, as described above. The modem of the user equipment 100 may perform step 308 of screening the cell satisfying the condition C1 from the network search result. The condition C1 and the cell satisfying the condition C1 have the same reference to the above description of step 306, and are not described herein again. The modem may also perform step 309 to determine whether the number of cells satisfying the condition C1 is less than n.

In an illustrative example, when the number of cells satisfying the condition C1 is not less than n, the modem may perform step 311a, determine n cells from the cells satisfying the condition C1 according to the parameter E1, and report the signal quality parameters of the n cells to the application processor. In one example, the parameter E1 may be a parameter used to characterize signal strength, such as RSRP. The cells meeting the condition C1 may be sorted according to RSRP from high to low, and then the signal quality parameters of the first n cells in the sorted sequence are reported to the application processor. In another example, the parameter E1 may be SINR. The cells satisfying the condition C1 may be sorted according to SINR from high to low, and then the signal quality parameters of the first n cells in the sorted sequence are reported to the application processor. The first n cells may be referred to as available cells.

In one illustrative example, the spectrum indication information may be set to include at least a frequency band list L1. That is, the spectrum D1 includes at least the dedicated frequency band of the user equipment 100. When the number of cells satisfying the condition C1 is less than n, the modem may execute step 310 to determine whether a network search has been performed on all frequency bands in the frequency spectrum D1. If the network searching is performed on all frequency bands in the frequency spectrum D1, the cells meeting the condition C1 are reported to the application processor. If the network searching is not performed on all the bands in the spectrum D1, the modem may perform step 307 again to continue the network searching on the band in the spectrum D1 where the network searching is not performed. Next, an example is presented.

In an example of this example, when the frequency band list L1 includes frequency band identifiers of multiple frequency bands, the modem may first perform network searching on any frequency band in the multiple frequency bands, and each time the network searching on one frequency band is completed, the modem may perform

steps

308, 309, and 310. For example, the frequency band list L1 can be set to include a frequency band B1, a frequency band B2, and a frequency band B3. In step 307, the modem may first perform a network search in band B1. Then, in step 308, a cell satisfying the condition C1 is selected from the cells obtained by searching in the frequency band B1. And when it is determined in step 309 that the number of cells satisfying the condition C1 is less than n, the modem performs step 310. The modem determines that a network search has not been performed on the band B2 and the band B3, via step 310. The modem may again perform step 307 to continue searching for networks in band B2. Then, in step 308, a cell satisfying the condition C1 is selected from the cells obtained by searching in the frequency band B2. And when it is determined in step 309 that the number of cells satisfying the condition C1 (the sum of the cells satisfying the condition C1 on the band B1 and the cells satisfying the condition C1 on the band B2) is less than n, the modem performs step 310. At the modem, it is determined that a network search has not been performed on band B3, via step 310. The modem may again perform step 307 to continue searching for networks in band B3. Then, in step 308, a cell satisfying the condition C1 is selected from the cells obtained by searching in the frequency band B3. And when it is determined in step 309 that the number of cells satisfying the condition C1 (the sum of cells satisfying the condition C1 on the band B1, cells satisfying the condition C1 on the band B2, and cells satisfying the condition C1 on the band B3) is less than n, the modem performs step 310. The modem determines that a network search has been performed on all bands in spectrum D1, via step 310. The modem may perform step 311b to report the signal quality parameters of all cells satisfying the condition C1, which may be referred to as available cells, to the application processor.

It can be appreciated that searching for a network takes a long time. In the example, the network searching is firstly carried out on one frequency band, and when the network searching result meets the condition, the network searching is not carried out on other frequency bands, so that the network searching time is saved, and the rapid evaluation of the network quality is realized.

In another example of this example, the spectrum indication information may be set to include a frequency band list L1 and frequency point identifiers of historical frequency points. That is, spectrum D1 includes both historical frequency bins and dedicated frequency bins. As described above, when the user equipment 100 attempts to access the NR cell, it preferentially attempts to access a cell on a history frequency point. Thus, when spectrum D1 includes historical frequency points, in step 307, the modem may first perform a network search on the historical frequency points. Then, through

steps

308 and 309, it is determined whether the cell on the history frequency point satisfying the condition C1 is less than n. When less than n, the modem may perform step 310. The modem determines that a network search has not been performed on the dedicated frequency band, via step 310. The modem may again perform step 307 to perform a network search on the dedicated frequency band. The subsequent steps of 307 are then performed again. Specifically, reference may be made to the above description, which is not repeated herein. It should be noted that, when the dedicated frequency band is a plurality of frequency bands, the modem may first perform network searching on any one of the plurality of frequency bands. Specifically, reference may be made to the above description, which is not repeated herein.

It can be appreciated that searching for a network takes a long time. In the example, the network searching is firstly carried out on one frequency point, and when the network searching result meets the condition, the network searching is not carried out on the exclusive frequency band, so that the network searching time is saved, and the rapid evaluation of the network quality is realized.

It should be noted that, the cell corresponding to the signal quality parameter reported by the modem to the application processor may be referred to as an available cell. That is, the signal quality parameters of the available cells are reported to the application processor. The signal quality parameters may include a combination of signal quality parameters including one or more of RSRP, SINR, RSRQ, RSSI.

In an illustrative example, when spectrum D1 includes multiple bands, the modem may perform

steps

309 and 310 after completing the network search for the multiple bands. Wherein when the number of cells satisfying the condition C1 is not less than n. The modem may perform step 311 a. When the number of cells satisfying the condition C1 is less than n, the modem may directly perform step 311 b. That is, in this example, when it is determined that the number of cells satisfying the condition C1 is less than n in step 310, the modem may not need to perform step 310 any more, but directly perform step 311 b.

In some embodiments, with continued reference to fig. 3, the application processor may execute step 312 to filter the cells reported by the modem according to a Public Land Mobile Network (PLMN) corresponding to the SIM card.

Typically, the user equipment 100 is accessed into the mobile communication network by means of a SIM card, which in one example may be an identification card of a global system for mobile communications (GSM) digital mobile phone user. In one example, the SIM card may also be used to store the user's id and key, and support the GSM system's authentication of the user. In one example, the SIM card may also be a Universal Subscriber Identity Module (USIM), which may also be referred to as an upgraded SIM card. Etc., which are not listed here. The SIM card may be understood as a key for the user equipment 100 to access the mobile communication network. It is understood that the SIM card has subscription information or network usage rights of the carrier subscriber, which represents the user identity. The subscriber identity corresponds to a Public Land Mobile Network (PLMN), that is, the SIM card corresponds to the PLMN. The PLMN corresponding to the SIM card may include one or more combinations of a local public land mobile network (HPLMN), an equivalent local PLMN (EHPLMN), and a Forbidden PLMN (FPLMN).

In this embodiment, the modem may report the parameter information of the cell to the application processor together with the signal quality parameter of the cell. It is understood that the parameter information of the cell includes cell identity (cell ID), PLMN ID and other information. And the PLMN corresponding to the PLMN ID is the PLMN to which the cell belongs. In step 312, the application processor may obtain, from the SIM card of the user equipment 100, the PLMN ID of the PLMN corresponding to the SIM card, and filter the cell reported by the modem according to the PLMN ID of the PLMN corresponding to the SIM card and the PLMN ID in the parameter information of the cell reported by the modem.

In one illustrative example, the PLMN corresponding to the SIM card of the user equipment 100 may be set to include the HPLMN. In step 312, a cell of which PLMN is the HPLMN corresponding to the SIM card may be screened out from the cells reported by the modem.

In one illustrative example, PLMNs corresponding to the SIM card of the user equipment 100 may be set to include EHPLMNs. In step 312, the PLMN to which the cell belongs may be selected from the cells reported by the modem as the EHPLMN corresponding to the SIM card.

In one illustrative example, a PLMN corresponding to a SIM card of the user equipment 100 may be set to include the FPLMN. In step 312, a cell, of which the PLMN belongs to is not the FPLMN corresponding to the SIM card, may be screened out from the cells reported by the modem.

The signal quality parameters of the cells screened in the above example may be used to determine the NR network quality in subsequent steps, or to determine information characterizing the NR network quality.

In some embodiments, step 312 may be performed by a modem. That is, in this embodiment, the modem searches for a cell on the spectrum D1, and when a cell meeting a preset condition (for example, the condition C1) is found, the cell meeting the preset condition may be screened according to the PLMN corresponding to the SIM card. The signal quality parameters of the screened out cells can be used to determine the NR network quality (or information characterizing the NR network quality) in a subsequent step.

In some embodiments, with continued reference to fig. 3, the user equipment 100 may perform step 313 to determine the network quality of the NR network according to the signal quality parameters of the cells screened out in step 312. Illustratively, step 313 may be specifically performed by an application processor of user equipment 100. Illustratively, step 313 may be specifically performed by a modem of the user equipment 100.

In one illustrative example, in step 313, one or more cells may be determined from the cells screened in step 312 according to the parameter E2, and the NR network quality (or information characterizing the NR network quality) may be determined according to the signal quality parameter of the one or more cells. Illustratively, the parameter E2 may be any one of RSPR, SINR, RSRQ, RSSI.

In one example of this example, the parameter E2 may be set to RSRP. In step 313, a cell with the largest RSRP may be determined from the cells screened in step 312, and the NR network quality may be determined according to the signal quality parameter of the cell with the largest RSRP. For example, the NR network quality score may be obtained by a table lookup, and the quality score may be used to characterize the NR network quality. Alternatively, the quality score may be referred to as information for characterizing the quality of the NR network. Table 1 shows a correspondence table between cell signal quality parameters and NR network quality levels.

TABLE 1

For example, the RSRP of the cell with the largest RSRP may be set to-100 dbm and the SINR to 20. From table 1, the quality score corresponding to the cell can be obtained as 90. The quality score of the cell may be used to characterize the NR network quality of the environment in which the user equipment 100 is located.

It should be noted that the above examples are only for illustration, and in other examples, the parameter E2 may be SINR, or RSRQ, or RSSI. The corresponding relation table of the cell signal quality parameter and the NR network quality grade can also be a relation table in other forms. In a specific implementation, the correspondence table between the cell signal quality parameter and the NR network quality level may be specifically set according to experiments or experience, and the parameter E2 may be selected.

In one illustrative example, in step 313, the NR network quality (or information characterizing the NR network quality) may be determined directly from the signal quality parameters of the cells screened in step 312. For example, the signal quality parameters of the cells may be set to include RSRP and SINR, and the user equipment 100 may calculate NR network quality by using the signal quality parameters of the cells screened according to step 312 through a fusion algorithm. The fusion algorithm may specifically refer to the introduction in the prior art, and is not described herein again.

In some embodiments, when the user equipment 100 searches for a cell satisfying a preset condition (e.g., the condition C1) through step 307, the NR network quality (or information characterizing the NR network quality) may be determined directly according to the signal quality parameter of the cell satisfying the preset condition. For example, the signal quality parameters of the cells may be set to include RSRP and SINR, and the user equipment 100 may calculate NR network quality by using the signal quality parameters of the cells satisfying the preset condition searched in step 307 by using a fusion algorithm. The fusion algorithm may specifically refer to the introduction in the prior art, and is not described herein again.

In some embodiments, returning to fig. 4A, the user equipment 100, upon determining the NR network quality, may transmit information for characterizing the NR network quality to the terminal equipment 400. When the terminal device 400 receives the information for characterizing the NR network quality, the NR network quality may be presented based on the data for characterizing the NR network quality. In one example, the information characterizing the quality of the NR network may be set to a quality score, e.g., a quality score of 90. The terminal device 400 may display an interface 450 as shown in fig. 4E so that the user can visually see the NR network quality (5G network quality) in the environment in which the user device is currently located. Illustratively, the interface 450 may also include a prompt message for prompting whether to proceed with the evaluation, and a corresponding ribbon (e.g., "yes" ribbon). The user may click the "yes" function area, so that the terminal device 400 may send a network evaluation instruction to the user device 100 to trigger the user device 100 to perform a network searching process, and evaluate the network quality of the NR in the environment where the user device 100 is located. Specifically, reference may be made to the above description of each embodiment shown in fig. 3, which is not described herein again.

In some embodiments, returning to fig. 5A-5C, the user equipment 100 may present the NR network quality when it is determined. For a specific presentation manner, reference may be made to the above description of fig. 4E, which is not described herein again.

By the cell searching method provided by the embodiment of the specification, the dedicated frequency band of the user equipment and/or the frequency point of the recently accessed NR cell can be searched, and the NR network quality in the environment where the user equipment is located can be evaluated according to the search result, so that the evaluation result can more truly reflect the network quality of the cell to be registered by the user equipment, and the user experience of evaluating the network quality and the communication experience of the user are improved.
