Description

Method and device for processing inter-system measurement results, terminal and storage medium

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method and an apparatus for processing inter-system measurement results, a terminal, and a storage medium.

Background

As 5G networks (e.g., communication networks implementing the 5GNR standard) have become commercially available, many handsets are also provided with the 5G network connection function.

Assuming that the mobile phone currently starts a service in a 4G network (for example, a communication network implementing the LET standard), in a normal case, if the network side detects that a cell of the 5G network exists in an environment where the mobile phone is located, a different system measurement instruction is issued to the mobile phone. After receiving the inter-system measurement instruction, the mobile phone performs corresponding measurement on the 5G network cell according to the instruction, and reports an inter-system measurement result (that is, the measurement result for the 5G network cell may include information such as network signal strength of the 5G network cell).

After receiving the measurement result of the different systems, the network side controls the redirection of the mobile phone according to specific conditions. If the network side issues redirection indication information to the mobile phone, the mobile phone redirects, that is, registers (camp) the 5G network cell, and if the registration fails, returns to the previous 4G network cell again.

Since redirection is to perform scanning and registration (scan + camp) of a cell in a 5G network after performing radio resource control release (rrc) in a 4G network, transmission between upper layer service data is affected by the redirection process, and from releasing resources of a 4G network cell to completing registration of the 5G network cell, data transmission cannot be performed in this project, so frequent redirection may seriously affect transmission of upper layer data, cause jamming, and affect use experience.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the related art, if the redirection of the network cell for the 5G network fails while the terminal is in the communication connection state of the 4G network, the handset may return to the previous network cell (i.e., the network cell of the 4G network). However, because the approximate rate of the environment where the terminal is located is not changed, the network cell of the 4G network will issue the inter-system measurement for the network cell (i.e., the network cell of the 5G network) that fails to register currently again, the terminal reports the inter-system measurement result to the network side, the network side will re-instruct the terminal to re-redirect again with a high probability, and the terminal will re-redirect again with a high probability and fail. The above steps are repeated in a circulating way, if the terminal is not moved out of the current environment, the terminal can be frequently redirected, and normal data transmission is seriously influenced, so that the network of the terminal is continuously abnormal, and the use experience is seriously influenced.

The disclosure provides a method for processing a measurement result of a different system, which is applied to a terminal (such as a mobile phone). In the method, an abnormal cell library is arranged in a terminal, and if a second cell of a second network is a network cell in the abnormal cell library, in the state that the terminal is registered in a first cell of a first network, after the second cell is subjected to inter-system measurement, the reporting of the inter-system measurement result to the first cell of the first network is forbidden. If the first cell cannot receive the measurement result of the different system, the first cell will not issue redirection indication information to the terminal, and the terminal will not register the abnormal second cell. That is, if the second cell in the environment where the terminal is located is an abnormal cell, the terminal does not perform registration of the second cell. The terminal is always in a registration state with the first cell, frequent redirection of the terminal is avoided, normal data transmission of the terminal is better guaranteed, and use experience is improved.

In one exemplary embodiment, a method for processing inter-system measurement results is provided and applied to a terminal. Referring to fig. 1, the method includes:

s110, receiving a measurement instruction for performing inter-system measurement on a second cell from a first cell;

s120, performing inter-system measurement on the second cell according to the received measurement instruction to obtain an inter-system measurement result of the second cell;

s130, determining whether the second cell is a network cell in the abnormal cell library;

and S140, if the second cell is determined to be the network cell in the abnormal cell library, forbidding reporting of the measurement result of the abnormal system to the first cell.

In step S110, the first cell belongs to a first network, and the second cell belongs to a second network different from the first network.

Wherein the measurement indication comprises cell information required to be measured.

For example, the measurement indication including the number, frequency point, etc. of the second cell may be used to determine the unique identity of the second cell.

The first network may be one of a 3G network (e.g., a communication network implementing UMTS standards), a 4G network (e.g., a communication network implementing LET standards), and a 5G network (e.g., a communication network implementing 5GNR standards), and the second network may also be one of a 3G network, a 4G network, and a 5G network, and the second network is different from the first network.

It should be noted that, in general, data transmission of the 5G network is considered to be better than that of the 4G network, and data transmission of the 4G network is considered to be better than that of the 3G network. When the second network is better than the first network, the first cell of the first network will issue a measurement instruction for performing inter-system measurement on the second cell of the second network. The terminal will receive the measurement indication.

In the case of example 1, the following examples,

the terminal has the capability of 5G network communication and is currently in a 4G network communication state, i.e., the terminal is registered with a network cell (i.e., a first cell) of the 4G network. In this state, a network side (e.g., a 4G network core network) detects that one or more (a plurality of two) network cells of the 5G network exist at the current location of the terminal, and the network side issues an inter-system measurement instruction about a network cell (i.e., a second cell) of a certain 5G network to the terminal based on a 4G network communication state, so that the terminal can receive a measurement instruction for performing inter-system measurement on the second cell from the first cell.

In step S120, after receiving the measurement indication, the terminal performs inter-system measurement on the second cell. The inter-system measurement may include detecting signal strength, signal stability, etc. information of the second cell. Inter-system measurements are then obtained. The inter-system measurement result corresponds to the content of the inter-system measurement, which may include information of signal strength, signal stability, and the like of the second cell.

In steps S130 and S140, the abnormal cell library may also be referred to as an abnormal cell list, and may include network cells with abnormal registration, that is, network cells that the terminal cannot normally register.

When the second cell belongs to the abnormal cell pool, that is, the second cell is a network cell in the abnormal cell pool, it indicates that the second cell is an abnormal cell. The terminal cannot normally register in the second cell. At this time, even though the terminal has obtained the inter-system measurement result of the second cell through the inter-system measurement, the terminal does not report the inter-system measurement result to the first network. The first network does not issue redirection information to the terminal for the second cell (the redirection information indicates that the terminal is redirected from the serving cell to another cell). The terminal will not register with the second cell. Therefore, the terminal is always in the first network communication state, useless data transmission caused by frequent redirection of the terminal is avoided, frequent network disconnection caused by frequent redirection of the terminal can also be avoided, the terminal is prevented from being blocked, and the user experience is improved.

When any terminal in the mobile network fails to register in the network cell, the network cell information which fails to register is uploaded to the cloud. The cloud may store information of the network cell(s) with failed registration (also referred to as abnormal cell) and form an abnormal cell library. In addition, the terminal may store the abnormal cell that has failed to register itself, and form an abnormal cell library, which is not limited herein.

In the method, when the terminal is in the first cell communication state, if a second cell in the environment where the terminal is located is an abnormal cell, the terminal is not registered with the second cell. The terminal is always registered in the first cell, namely, the terminal is always in the communication state of the first cell, so that frequent redirection of the terminal is avoided, normal data transmission of the terminal is better ensured, and user experience is improved.

In one exemplary embodiment, a method for processing inter-system measurement results is provided and applied to a terminal. In the method, after determining that the second cell belongs to the abnormal cell bank, the method further includes: and accumulating the number of the report forbidding times, wherein the number of the report forbidding times refers to the number of the report forbidding times of the measurement result of the different system aiming at the second cell.

And accumulating the number of the report prohibiting times, and increasing the current report prohibiting times by 1 time when the second cell is determined to be the network cell of the abnormal cell bank once.

In the case of example 1, the following examples,

the terminal receives a measurement indication for performing inter-system measurement on a second cell from a first cell. Suppose that the number of prohibited reporting times of the second cell of the terminal is currently 0. According to the foregoing description, if the terminal determines that the second cell is a network cell in the abnormal cell pool, reporting of the inter-system measurement result for the second cell is prohibited. Meanwhile, the number of prohibited reporting times of the second cell is accumulated. That is, the number of prohibited reporting times of the second cell is increased by 1, and the updated number of prohibited reporting times is 1.

In the case of example 2, the following example was carried out,

the terminal receives a measurement indication for performing inter-system measurement on a second cell from a first cell. Suppose that the number of prohibited reporting times of the second cell of the terminal is currently 3. And if the second cell is determined to be the network cell in the abnormal cell library, updating the number of the report prohibition times to 4.

In the method, the terminal accumulates the number of prohibited reporting times of the second cell, so that the network condition of the second cell can be judged subsequently according to the number of prohibited reporting times of the second cell, and the improvement of the second cell is facilitated.

In one exemplary embodiment, a method for processing inter-system measurement results is provided and applied to a terminal. The method further comprises the following steps:

s210, if the number of times of report prohibition is determined to be more than or equal to the preset number of times, generating a first message;

s220, according to the first message, triggering the updating of the location area, and prohibiting the terminal from registering to a second cell;

and S230, sending a first message to the first network.

The first message is used to prohibit the terminal from registering with the second cell, that is, prohibit the terminal from registering with the second cell.

As shown in fig. 1a, the first message may be generated by the terminal itself, and the terminal generates the first message and then transmits the first message from a bottom layer (e.g., RRC layer (radio resource control layer)) to an upper layer (e.g., NAS layer (non-access stratum)).

In the method, the terminal triggers a location area update according to the first message, and updates the second network connection parameter of the terminal (the second network connection parameter is used for the terminal to perform the connection of the second network, that is, the second network connection parameter is used for registering with the network cell of the second network). The terminal prohibits its own connectivity with the second network and thus its own registration with the network cell of the second network.

According to an embodiment, the terminal may send a location area update request to the first cell according to the first message. The location area update request includes a plurality of parameters such as a terminal capability indication (e.g., an indication of the capability of the terminal to access the network to which the second cell belongs). In an embodiment, the terminal sends a location area update request with a removable second network capability related parameter, which informs the first cell that the terminal does not support the capability of the cell registered in the second network. In this way, the terminal may disable its own connectivity to the second network, thereby disabling its own registration with the network cell of the second network.

Wherein, the second network connection parameter can be N1mode parameter and DCNR (Dual Connectivity E-UTRAN and NR) parameter. The N1mode parameter is used to indicate whether the terminal supports the capability of connecting with an SA (independent networking), i.e., a 5G network in the form of an SA. When the N1mode parameter is 0, the terminal does not support the SA capability; when the N1mode parameter is 1, it indicates the terminal support and SA capability. The DCNR parameter is used to indicate whether the terminal supports a capability of connecting to NSA (non-independent networking) (a capability of connecting to a 5G network in the form of NSA). When the DCNR parameter is 0, the terminal does not support the NSA capability; when the DCNR parameter is 1, it indicates that the terminal supports NSA capability.

Meanwhile, the terminal sends the first message to the first cell, the first cell knows that the terminal is forbidden to register to the second cell, and the first cell does not send a measurement instruction for performing inter-system measurement on the second cell to the terminal. Therefore, the terminal can be prevented from frequently carrying out different system measurement aiming at the second cell, and the power consumption of the terminal can be further reduced.

In the case of example 1, the following examples,

the preset times is 5 times, the terminal is currently in a communication state of a 4G network, and if the number of prohibited reporting times for a second cell (belonging to the 5G network) reaches 5 times, the terminal triggers generation of a message (i.e., a first message) for removing connection capability between the second cell and the 5G network. The terminal may trigger a location area update according to the message. And when the location area is updated, updating the 5G network connection parameters of the terminal, and forbidding the terminal to establish the communication connection capability of the 5G network. I.e. registration with a network cell of the 5G network is prohibited. Wherein updating the 5G network connection parameters of the terminal is used to remove SA and NSA capabilities of the terminal for the 5G network. After the terminal removes the capability, the terminal cannot perform communication connection of the 5G network and cannot register with the network cell of the 5G network.

Meanwhile, the terminal sends the message to a core network of the 4G network (for example, referring to MME in fig. 1a, MME refers to a network node, which is a part of the core network and is responsible for a signaling processing part), and informs the core network that the terminal prohibits the connection capability with the 5G network, and cannot register with a network cell of the 5G network, and the core network does not issue a measurement instruction for performing inter-system measurement on the network cell of the 5G network.

It should be noted that the location area update in the method is similar to the location area update in the prior art, and the method focuses on setting up a new mechanism for triggering the location area update (i.e. triggering the location area update based on the first message), and updating the network connection parameters when the location area update occurs, so that the terminal temporarily disables the connection capability with the second network (i.e. disables registration with the network cell of the second network).

In the method, when the number of times of report prohibition aiming at the second cell is excessive, the registration capability of the terminal aiming at the second cell is removed, the first network does not instruct the terminal to carry out the different-system measurement aiming at the second cell any more, not only can frequent redirection be avoided, but also the terminal can be prevented from frequently carrying out the different-system measurement aiming at the second cell, and the power consumption of the terminal is reduced.

In one exemplary embodiment, a method for processing inter-system measurement results is provided and applied to a terminal. After prohibiting the terminal from registering with the second cell, the method further includes: and after the preset time is determined, triggering the location area updating again, and recovering the terminal to register to the second cell.

Wherein, when the terminal is forbidden to register to the second cell, a timing module can be started. The timing module is used for timing the forbidden time length. A preset time period (e.g., 1 hour or 12 hours) may be set in the timer module. After the prohibition lasts for the preset duration, the terminal can generate a second message, and according to the second message, the terminal triggers the location area update once again to recover the registration of the terminal to the second cell. I.e. the capability of the terminal to register with the second cell is restored.

Meanwhile, the terminal can also send a second message to the core network of the first network to inform the first cell that the terminal recovers the connection capability for the second network, and the first cell can recover to send a measurement instruction for performing inter-system measurement on the network cell of the second network to the terminal.

Wherein the second message is similar to the first message. Referring to fig. 1a, the second message may also be generated by the terminal itself, and the terminal generates the second message and then transmits the second message from a bottom layer (e.g., RRC layer (radio resource control layer)) to an upper layer (e.g., NAS layer (non-access stratum)).

In the method, the terminal can be prevented from frequently carrying out inter-system measurement, and the terminal can be prevented from permanently losing the connection capability with the second network. Namely, the method can also recover the previously forbidden connection capability (also called registration capability), ensure that the terminal can continue to use the second network and can continue to register in the network cell of the second network, and further improve the use experience of the user.

and if the preset conditions are met, resetting the abnormal cell library.

The resetting of the abnormal cell library may be clearing the network cell in the abnormal cell library, or restoring the abnormal cell library to a factory state (the abnormal cell library is preset in advance before the terminal leaves the factory), or deleting the abnormal cell library (the abnormal cell library is not preset before the terminal leaves the factory).

The preset conditions may be satisfied: a reset period to reset the abnormal cell is reached and/or the terminal is restarted.

For example, the abnormal cell is reset for 1 month, that is, every month, the abnormal cell pool is reset.

For another example, when the terminal is restarted, the abnormal cell pool is reset at the same time.

Of course, meeting the preset condition may also include other situations, for example, determining that the preset condition is met may include:

and when the protocol layer prohibits the cell bank from being reset, determining that the preset condition is met.

The protocol layer forbidden cell library refers to a cell library formed by network cells to which the wireless connection protocol layer of the terminal is forbidden to connect. The protocol layer prohibits the network cells in the cell library from being network cells which are explicitly prohibited by the terminal from registering.

In general, a protocol layer forbidden cell library is set in a terminal, and network cells in the protocol layer cell library are cells for which the network side explicitly rejects the terminal registration and all have an explicit rejection reason value. The protocol layer prohibits cell pool resetting (including updating and/or purging) according to network protocol requirements. In addition, in general, the network cell included in the forbidden cell library of the protocol layer is different from the network cell included in the abnormal cell library, and the network cell in the abnormal cell library is a network cell which is not included in the forbidden cell library of the protocol layer and is abnormally registered.

For example, the duration of rejecting access by a cell in the protocol layer forbidden cell bank is 12 hours each time, and then the protocol layer forbidden cell bank can be reset (for example, cleared) after 12 hours, and the abnormal cell bank can also be reset at the same time, so as to ensure synchronous reset of the two cell banks.

For another example, each time the terminal is restarted (or switched to the flight mode), the protocol layer forbidden cell bank is reset, and when the protocol layer forbidden cell bank is reset, the abnormal cell bank can also be synchronously reset, so as to ensure the synchronous reset of the two cell banks. In the method, the abnormal cell library and the existing protocol layer in the terminal forbid synchronous resetting of the cell library so as to realize an improvement mechanism of synchronous resetting of related network configuration parameters, reduce power consumption and complexity of program design and further improve the use experience of users.

s310, if the second cell is determined not to belong to the network cell in the abnormal cell library, reporting the measurement result of the different system to the first cell;

s320, receiving redirection information sent by the first cell;

s330, registering to the second cell according to the redirection information;

and S340, if the registration to the second cell is determined to be failed, adding the second cell to the abnormal cell library.

In step S310, if it is determined that the second cell does not belong to the network cell in the abnormal cell pool, it indicates that the second cell is not considered as an abnormal cell. The terminal can report the measurement result of the different system to the first cell for the first cell to perform the next processing according to the measurement result of the different system.

In step S320, redirection information is sent by the first cell in response to the inter-system measurement result. That is, after receiving the inter-system measurement result, the first cell generates corresponding redirection information according to the inter-system measurement result, and then issues the redirection information to the terminal. The terminal may receive the redirection information.

In step S330, after receiving the redirection information, the terminal registers with the second cell according to the redirection information. In this process, the first network needs to be disconnected (i.e. the terminal is no longer registered with the first cell). Therefore, the terminal is actually in a disconnected state in the redirection process, and data transmission cannot be normally performed.

In step S340, if it is determined that the registration with the second cell fails, the terminal returns to the registration state with the first cell. That is, the terminal returns to the communication connection state of the first network again, and data transmission is realized through the first network.

Meanwhile, the terminal can also add the second cell to the abnormal cell library. If the inter-system measurement is performed again for the second cell, the terminal may determine that the second cell belongs to the abnormal cell pool because the second cell has been added to the abnormal cell pool. The terminal may prohibit reporting the inter-system measurement result of the second cell to the first cell. The first cell does not send the redirection information to the terminal any more. The terminal is no longer registered with the second cell. The method avoids frequent redirection of the terminal, ensures normal data transmission of the terminal and improves use experience.

It should be noted that, in the method, the abnormal cell library may be preset in the terminal before the terminal leaves the factory, may be set by a subsequent user, or may be established after the first redirection failure.

In the case of example 1, the following examples,

and presetting an abnormal cell library before the terminal leaves a factory. The number of network cells in the abnormal cell library is 0, that is, the abnormal cell library is an empty library, and no abnormal cell is set. When a network cell which fails to be redirected appears, the network cell can be added to the abnormal cell library. And repeating the steps, and gradually adding the network cells in the abnormal cell library.

In the case of example 2, the following example was carried out,

after the user purchases the terminal. In the using process, an abnormal cell library is automatically established. The abnormal cell pool may be an empty pool to which no network cells are added. It can be understood that the user may also add the network cell which the user thinks the signal is not good to the abnormal cell library. When the network cell which fails to be redirected occurs, the network cell can be added to the abnormal cell library. And the network cells in the abnormal cell library are gradually added by analogy.

In the example 3, the first and second images are,

after the terminal fails to redirect for the first time, an abnormal cell library can be established and the network cell failed to redirect is added into the abnormal cell library. At this time, only the network cell with the redirection failure exists in the abnormal cell library. When a new network cell failing to be redirected appears again, the network cell can be added to the abnormal cell library. And the network cells in the abnormal cell library are gradually added by analogy.

In the method, if the second cell is determined not to be the cell in the abnormal cell library, the measurement result of the abnormal system is reported to the first network normally. After the network side receives the measurement result of the different system, if the measurement result meets the requirement, the network side can issue redirection information to the terminal according to the measurement result of the different system. After receiving the redirection information, the terminal performs redirection, that is, registers with the second cell.

After the terminal fails to be redirected, the network cell with failed registration can be added to the abnormal cell library, so that the terminal is prevented from being frequently redirected aiming at the network cell, frequent outage (namely network connection terminal) can be better avoided, normal transmission of data is guaranteed, and the use experience of a user is improved.

In an exemplary embodiment, a method for processing inter-system measurement results is provided, which is applied to a terminal and a device (e.g., a base station) on a network side. Referring to fig. 1a, a UE refers to a user equipment, i.e. a terminal in the present application. eNB (eNode-B) denotes a base station. MME refers to a network node, which is part of the core network, which is responsible for the signaling processing part. The double-headed arrows in the figure indicate the presence of interaction between the two, i.e. the transmission of information. Wherein, NAS stands for the non-access stratum, RRC stands for the control protocol layer of the radio resource, PDCP is the abbreviation of the agreement of convergence of packet data; RLC refers to the radio link control sublayer; MAC refers to the media access control layer; PHY refers to the port physical layer. The communication between the layers can be completed through message passing.

Referring to fig. 1a, NAS belongs to a non-access stratum and does not pass through eNB; the RRC, PDCP, RLC, MAC and PHY constitute an access layer. The RRC is responsible for air interface connection, belongs to a connection layer and only exists in a control plane; the PDCP carries out segmented chaining, header compression and encryption on data from an upper layer, and if the data is VoLTE, a voice packet is compressed; the RLC is only available on a data plane, and has a radio link control function, mainly ARQ error correction; MAC is mainly HARQ and scheduling functions.

In the method, it is assumed that a terminal (i.e., a UE in the figure) is currently in a communication connection state of a 4G network, and the terminal is registered in a first cell of the 4G network, where the first cell may refer to an area covered by a signal of a certain base station of the 4G network. That is, the terminal is communicatively connected to the above-described base station (i.e., eNB in the figure) of the 4G network.

The first cell sends a measurement instruction for performing inter-system measurement on a second cell (belonging to a 5G network, and similarly, the second cell may refer to an area covered by a signal of a certain base station of the 5G network) to the terminal for the first time. Wherein the base station, which is actually a 4G network (i.e. eNB in fig. 1 a), sends a measurement indication to the terminal.

And the terminal receives the measurement instruction, and can perform inter-system measurement on the second cell according to the measurement instruction to obtain an inter-system measurement result.

After the terminal obtains the inter-system measurement result, the first inter-system measurement result may be reported to the first cell (i.e., the inter-system measurement result is reported to the base station forming the first cell). And the first cell receives the measurement result of the different system and issues redirection information aiming at the second cell to the terminal according to the measurement result of the different system. In practice, the terminal reports the measurement result of the different system to the base station of the 4G network, and then the base station issues redirection information to the terminal based on the measurement result of the different system.

The terminal receives the redirection information and registers to the second cell according to the redirection information (namely, communication connection is established to a base station forming the second cell). And if the registration to the second cell is determined to be failed, establishing an empty abnormal cell library, and adding the second cell to the abnormal cell library.

And when the first cell issues the measurement instruction for performing the inter-system measurement on the second cell to the terminal again. And the terminal receives the measurement instruction and performs the inter-system measurement on the second cell again according to the measurement instruction to obtain the inter-system measurement result.

In addition, since the terminal can determine that the second cell belongs to the network cell in the abnormal cell library, the reporting of the measurement result of the different system to the first cell can be prohibited, and the number of prohibited reporting times is accumulated to be 1.

And repeating the steps until the number of times of forbidding reporting is accumulated to a preset number of times (for example, 5 times).

The RRC layer of the terminal may generate the first information and transmit the first information to the NAS layer of the terminal. And the NAS layer triggers the updating of the location area according to the first information and forbids the terminal to register to the second cell.

Meanwhile, the terminal reports the first information to a network node (i.e., MME in fig. 1 a) of the 4G network, and informs that the terminal has prohibited to register with the second cell (e.g., remove the connection capability between the terminal and the 5G network). The base station of the 4G network does not send a measurement instruction to the terminal for the second cell to perform inter-system measurement.

After a preset time period (e.g., 24 hours), the RRC layer of the terminal may generate the second message and transmit the second message to the NAS layer of the terminal. And the NAS layer triggers the updating of the location area again according to the second information, and the recovery terminal registers to the second cell.

Meanwhile, the terminal reports the second information to the network node of the 4G network, and informs that the base station terminal of the 4G network has recovered registration with the second cell (i.e., the terminal recovers the previously removed connection capability with the 5G network), and the first cell can continue to issue a measurement instruction for performing inter-system measurement on the network cell of the 5G network.

The method can avoid frequent redirection of the terminal. Especially, under the condition that the position of the terminal is not changed, the terminal can be effectively prevented from being frequently redirected to the same network cell and being measured by different systems of the same network cell, so that the power consumption of the terminal is reduced, the terminal can be prevented from being frequently cut off, the data transmission is prevented from being influenced, and the use experience of a user is improved.
