The technical solution of the present invention is further illustrated by the following examples. As shown in fig. 2, a schematic diagram of an embodiment of a method for prioritizing network endec cells in an embodiment of the present invention may include:

201. determining a target cell set, wherein the target cell set comprises a first cell set, and all cells in the first cell set are ENDC cells and are sorted according to the order of channel quality.

Optionally, the obtaining of the first cell set may include: the terminal equipment acquires an available cell in an initial network scanning stage; adding, by the terminal device, cells, in the first target available cell, of which Reference Signal Receiving Power (RSRP) is greater than or equal to a Power threshold and Reference Signal Receiving Quality (RSRQ) is greater than or equal to a Quality threshold, into the endec cell set to obtain a first cell set; and the first target available cell is a cell which is successfully matched with the preset ENDC cell set in the available cells.

Exemplarily, the UE acquires an initial network scanning stage to scan out all available cells (available cells); and matching and judging each available cell (available cell) with a cell in a preset ENDC cell set, wherein the successfully matched available cell can judge the RSRP and the RSRQ. For example, when RSRP > -T1 & & RSRQ > -T2, the available cell is added to the endec preferred cell set to obtain a first cell set, where T1 is the power threshold and T2 is the quality threshold. It can be understood that, the matching decision between each available cell and a cell in the preset endec cell set is mainly to decide whether each available cell belongs to a cell in the preset endec cell set.

Optionally, the preset endec cell set includes a preset static endec cell set, and/or a preset dynamic endec cell set. It is to be understood that the order of cells in the preset static endec cell set and the preset dynamic endec cell set is not limited.

Optionally, the cells in the first cell set are sorted in order from high channel quality to low channel quality, or sorted in order from low channel quality to high channel quality.

It can be understood that the preset static endec cell set may also be referred to as a static embedded endec cell set or a static embedded data set, which is not limited specifically. And embedding high-priority ENDC cell information and maintaining a static ENDC cell information set through real network debugging experience and relevant information disclosed by an operator.

The preset dynamic endec cell set may also be referred to as a dynamic history endec cell set, or a dynamic history record data set, which is not limited specifically. Namely, historical endec cells can be dynamically learned and recorded: compared with static pre-embedded frequency points, the method has the advantages that the configuration of a network environment is complex, the static pre-embedded cell mode cannot well cover various ENDC cell information configured by the network, only a small part of ENDC cell information can be pre-embedded according to some prior information, and various cells which are not statically pre-embedded but are ENDC exist in the actual network environment, so that a mode of dynamically learning and recording historical ENDC cells can be introduced. Illustratively, when the cell is found to be an endec cell after the actual UE camps on the network, and does not belong to the cell in the current static embedded endec cell set, or does not belong to the cell in the dynamic history endec cell set, the cell is recorded in the dynamic history endec cell set. Optionally, since the real network has multiple combinations, in order to not affect the network searching performance and meet the requirement of fast network camping endec cell, the dynamic history endec cell set limits a certain number of cell records. For example, N, the number of ENDC cells recorded in the queue is less than N, and a new ENDC cell is directly added to the tail of the queue; and when the number of the ENDC cells recorded in the queue is equal to N, removing the ENDC cell information at the head of the queue, and adding new ENDC cell information at the tail of the queue.

202. And performing network residence according to the sequence of the cells with the channel quality from high to low in the first cell set.

Illustratively, the UE initiates the network camping attempts in sequence according to the order of the channel quality from high to low in the first cell set.

203. And under the condition that the network camping is not successful in the first cell set, performing network camping according to the sequence of the cells with the channel quality from high to low in the second cell set.

Optionally, the target cell set further includes a second cell set, and the cells in the second cell set are sorted according to the order of the channel quality.

Optionally, the obtaining of the second cell set may include, but is not limited to, the following implementation manners:

implementation mode 1: the terminal equipment adds the second target available cell into the non-ENDC cell set to obtain a first non-ENDC cell set, and the first non-ENDC cell set is used as a second cell set; and the second target available cell is a cell which fails to be matched with the preset ENDC cell set in the available cells, and the available cell is an available cell in an initial network scanning stage acquired by the terminal equipment.

Exemplarily, the UE acquires an initial network scanning stage to scan out all available cells (available cells); matching and judging each available cell (available cell) with a cell in a preset ENDC cell set, adding the failed available cell into a non-ENDC preferred cell set to obtain a first non-ENDC cell set, wherein the first non-ENDC cell set can be used as a second cell set.

Implementation mode 2: adding the second target available cell into the non-ENDC cell set by the terminal equipment to obtain a first non-ENDC cell set; the terminal equipment adds the cells of which the reference signal receiving power is smaller than a power threshold value and/or the reference signal receiving quality is smaller than a quality threshold value in the first target available cell into a first non-ENDC cell set to obtain a second cell set; and the second target available cell is a cell which fails to be matched with the preset ENDC cell set in the available cells.

Exemplarily, the UE acquires an initial network scanning stage to scan out all available cells (available cells); and matching and judging each available cell (available cell) with a cell in a preset ENDC cell set, and adding the failed available cell into a non-ENDC preferred cell set to obtain a first non-ENDC cell set. Further, the successfully matched available cell may be determined again by RSRP and RSRQ. For example, when RSRP < T1 and/or RSRQ < T2, the available cell may be added to the second non-endec preferred cell set to obtain a second cell set, where T1 is the power threshold and T2 is the quality threshold.

Implementation mode 3: and the terminal equipment adds the cells of which the reference signal received power is less than the power threshold and/or the reference signal received quality is less than the quality threshold in the first target available cell into the non-ENDC cell set to obtain a second cell set.

Illustratively, when the preset ENDC cell set comprises a preset static ENDC cell set, and the preset dynamic ENDC cell set. For example:

the provisioning of the static endec cell set may include: cell1, cell2, cell 3.

The provisioning of the dynamic endec cell set may include: cell1, cell3, cell5, cell7, cell9, cell11, cell13, cell15, cell17, and cell 19.

The currently available cells may include: cell1, cell3, cell7, cell9, cell2, cell4, cell6, cell8, and cell 10.

Then, each cell in the currently available cells is matched with a preset endec cell set, and the endec cells successfully matched are: cell1, cell2, cell3, cell7, cell 9; the ENDC cells with failed matching are: cell4, cell6, cell 8.

Further, the RSRP and RSRQ of the successfully matched endec cell are determined, and the endec cell with RSRP > T1& & RSRQ > -T2 is: cell1, cell3, cell7, cell 9; wherein, the cell2 does not satisfy RSRP > -T1 & & RSRQ > -T2.

At this time, the first cell set may include: cell1, cell3, cell7, and cell 9.

The second set of cells may include: cell4, cell6, cell 8; may also include: cell2, cell4, cell6, and cell 8.

Optionally, the cells in the second cell set are sorted in order from high channel quality to low channel quality, or sorted in order from low channel quality to high channel quality.

For example, in the case that the UE sequentially initiates the network camping attempts in sequence in the cells in the first cell set but does not succeed in network camping, the UE sequentially initiates the network camping attempts in sequence according to the order of the cells with channel quality from high to low in the second cell set. That is, when the cell camping in the first cell set fails, the terminal device may perform network camping according to the sequence of the cells with the channel quality from high to low in the second cell set, so as to ensure the normal operation of the UE service.

204. And under the condition that the preset ENDC cell set comprises a preset dynamic ENDC cell set, after the network residence is successful, determining the current service cell which is successful in the network residence.

205. And if the current service cell belongs to the cells of the second cell set and is the ENDC cell, adding the current service cell into the preset dynamic ENDC cell set to obtain the updated preset dynamic ENDC cell set.

For example, after the UE successfully camps on the network, it is determined whether a current serving cell (serving cell) needs to be newly added to the dynamic history endec cell set, and when a determination criterion may simultaneously satisfy the following conditions, the UE is added to the dynamic history endec cell set:

condition 1: the current serving cell is a cell in the second cell set;

condition 2: the current serving cell is currently updated to an endec cell.

Optionally, the adding, by the terminal device, the current serving cell into the preset dynamic endec cell set to obtain an updated preset dynamic endec cell set, where the updating may include:

if the number of the cells in the preset dynamic ENDC cell set does not reach a preset threshold value, adding the current service cell into the preset dynamic cell set to obtain an updated preset dynamic ENDC cell set;

and if the number of the cells in the preset dynamic ENDC cell set reaches a preset threshold value, deleting part of the cells in the preset dynamic ENDC cell set, and adding the current service cell into the preset dynamic cell set in which the part of the cells are deleted to obtain an updated preset dynamic ENDC cell set.

Optionally, the adding, by the terminal device, the current serving cell into the preset dynamic cell set to obtain an updated preset dynamic endec cell set, where the updating includes: the terminal equipment adds the current service cell to the tail of the queue in the preset dynamic cell set to obtain an updated preset dynamic ENDC cell set;

the method for acquiring the updated preset dynamic ENDC cell set by the terminal equipment includes the following steps: and the terminal equipment deletes the head cell of the queue in the preset dynamic ENDC cell set, and adds the current service cell to the tail of the queue in the preset dynamic cell set of the deleted head cell of the queue to obtain the updated preset dynamic ENDC cell set.

Illustratively, the current serving cell if the terminal device successfully camps on the network is cell 4. Since cell4 previously belonged to a cell in the second set of cells, however, the terminal device now detects that cell4 has been updated to an endec cell. Then the terminal device may update cell4 this endec cell into a preset dynamic endec cell set.

Optionally, before the updating, it may be determined whether the number of the endec cells in the preset dynamic endec cell set has reached a preset threshold (for example, 12), and if not, the cell4 may be directly added to the tail of the preset dynamic endec cell set, where the updated preset dynamic endec cell set may include: cell1, cell3, cell5, cell7, cell9, cell11, cell13, cell15, cell17, cell19 and cell 4.

Optionally, before the updating, it may be determined whether the number of the endec cells in the preset dynamic endec cell set has reached a preset threshold (for example, 10), and if the number of the endec cells in the preset dynamic endec cell set has reached the preset threshold, the cell at the head of the queue of the preset dynamic endec cell set may be directly deleted, and then the cell4 is added to the tail of the queue of the preset dynamic endec cell set, so that the updated preset dynamic endec cell set may include: cell3, cell5, cell7, cell9, cell11, cell13, cell15, cell17, cell19, and cell 4.

Optionally, step 203 and step 205 are optional steps. For the update of the preset dynamic endec cell set, reference may be made to the relevant description in step 201 for a specific example, and details are not described here.

It should be noted that the embodiment of the present invention may be applied to terminal devices of various manufacturers. Aiming at meeting the requirement of a network preference ENDC cell and simultaneously ensuring the channel quality of the selected cell, a network searching strategy of the network preference ENDC cell is realized by designing a static pre-buried cell set and/or a dynamic historical ENDC cell set, and simultaneously setting a threshold value T1 of RSRP and a threshold value T2 of RSRQ.

In the embodiment of the invention, a target cell set in an initial network scanning stage is obtained, wherein the target cell set comprises a first cell set, and cells in the first cell set are sequenced according to the sequence of channel quality; according to the sequence of the cells with the channel quality from high to low in the first cell set, network residence is carried out; further, under the condition that network camping is not successful in the first cell set, network camping is performed according to the sequence of the cells with the channel quality from high to low in the second cell set. The target cell set further includes a second cell set, and the cells in the second cell set are sorted according to the order of the channel quality. It should be noted that the first cell set and the second cell set do not need to be combined. Namely, in the NSA networking mode, the ENDC cell can be rapidly camped preferentially while the channel quality state of the cell camping on the network is ensured to be good, so that better 5G use experience is provided for users.

As shown in fig. 3, a schematic diagram of another embodiment of a method for prioritizing network endec cells in an embodiment of the present invention may include:

Illustratively, the UE sorts the first cell set and the second cell set according to channel quality, and after sorting of the two cell sets is completed, the two sorted cell sets are sorted according to: and finally, the UE performs network residence attempts in sequence according to the sequencing result and the sequence of the channel quality from high to low. For example: the target cell set is: cell1, cell3, cell7, cell9, cell4, cell6, cell 8; or cell1, cell3, cell7, cell9, cell2, cell4, cell6 and cell 8. Wherein the first set of cells comprises: cell1, cell3, cell7, and cell 9. The second set of cells may include: cell4, cell6, cell 8; alternatively, it comprises: cell2, cell4, cell6, and cell 8.

Referring to fig. 6, the handset includes: radio Frequency (RF) circuitry 610, memory 620, input unit 630, display unit 640, sensor 650, audio circuitry 660, wireless fidelity (WiFi) module 670, processor 680, and power supply 690. Those skilled in the art will appreciate that the handset configuration shown in fig. 6 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 6:

the RF circuit 610 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 680; in addition, the data for designing uplink is transmitted to the base station. In general, RF circuit 610 includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 610 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.

The memory 620 may be used to store software programs and modules, and the processor 680 may execute various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 620. The memory 620 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 620 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 630 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 630 may include a touch panel 631 and other input devices 632. The touch panel 631, also referred to as a touch screen, may collect touch operations of a user (e.g., operations of the user on the touch panel 631 or near the touch panel 631 by using any suitable object or accessory such as a finger or a stylus) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 631 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 680, and can receive and execute commands sent by the processor 680. In addition, the touch panel 631 may be implemented using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 630 may include other input devices 632 in addition to the touch panel 631. In particular, other input devices 632 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 640 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The Display unit 640 may include a Display panel 641, and optionally, the Display panel 641 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 631 can cover the display panel 641, and when the touch panel 631 detects a touch operation thereon or nearby, the touch panel is transmitted to the processor 680 to determine the type of the touch event, and then the processor 680 provides a corresponding visual output on the display panel 641 according to the type of the touch event. Although in fig. 6, the touch panel 631 and the display panel 641 are two independent components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 631 and the display panel 641 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 650, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 641 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 641 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuit 660, speaker 661, and microphone 662 can provide an audio interface between a user and a cell phone. The audio circuit 660 may transmit the electrical signal converted from the received audio data to the speaker 661, and convert the electrical signal into an audio signal through the speaker 661 for output; on the other hand, the microphone 662 converts the collected sound signals into electrical signals, which are received by the audio circuit 660 and converted into audio data, which are processed by the audio data output processor 680 and then transmitted via the RF circuit 610 to, for example, another cellular phone, or output to the memory 620 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 670, and provides wireless broadband Internet access for the user. Although fig. 6 shows the WiFi module 670, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 680 is a control center of the mobile phone, and connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 620 and calling data stored in the memory 620, thereby performing overall monitoring of the mobile phone. Optionally, processor 680 may include one or more processing units; preferably, the processor 680 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 680.

The handset also includes a power supply 690 (e.g., a battery) for powering the various components, which may preferably be logically connected to the processor 680 via a power management system, such that the power management system may be used to manage charging, discharging, and power consumption.
