In The related art, The terminal cannot determine The type of The Fourth Generation mobile communication (4G) neighbor cell corresponding to The serving cell when performing cell reselection. Specifically, from the perspective of the terminal, the 4G cell and the Non-independent Networking (NSA) cell are both intra-system or inter-system neighboring cells with equal priority; that is to say, when the signal strength of the 4G cell in the overlapping coverage area is higher than that of the NSA cell, even if the NSA cell already satisfies the camping condition, the terminal will still select to camp on the 4G cell, so that the terminal always operates in the 4G mode and cannot be switched to the NSA mode with stronger transmission capability, which results in reducing the probability that the terminal operates in the NSA mode, and greatly reduces user experience.

Detailed Description

So that the manner in which the features and elements of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

It should be noted that in the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

As 4G enters The commercial-scale phase, 2020 and future-oriented fifth generation mobile communication (5G) technology has become a global research and development hotspot. Currently, The Third Generation Partnership Project (3 GPP) defines two schemes for 5G New air interface (NR) networking, SA and NSA respectively.

Wherein, NSA refers to independently deploying a control plane (4G network bearing control signaling) in a 4G network, deploying a user plane (5G and 4G networks bearing user plane data) in a 5G and 4G network together, or independently deploying a user plane (only 5G network bearing user plane data) in a 5G network; and SA refers to the independent deployment of control plane and user plane in 5G network (5G network independently carries control signaling and user plane data). For the SA mode, a 5G end-to-end network needs to be deployed independently, and a base station and a core network are newly established, so that the 5G network can work independently of a 4G network. For the NSA mode, the existing 4G network can be relied on, so that the pre-issued requirements of part of operators on the 5G network are met.

In practical applications, the existing network 4G cells can be divided into two types according to the NSA method, which are a pure 4G cell (referred to as "4G cell" herein) that does not support the NSA method and a 4G cell (referred to as "NSA cell" herein) that supports the NSA method. When the 4G cell and the NSA cell are serving as serving cells, the terminal may be notified whether the cell has the NSA capability through signaling or the like. When the 4G cell and the NSA cell are used as 4G neighbor cells corresponding to the serving cell, both exist in the form of 4G cells, and the terminal cannot determine the type of the neighbor cell before finishing cell reselection and residing to the target cell.

Currently, according to different requirements of operators, in practical network deployment, there may exist coverage of both 5G NSA network and 4G network in a certain area, that is, an NSA cell and a 4G cell overlap to cover a certain area. For the area covered by the NSA cell and the 4G cell in an overlapping way, when the terminal is resided in the 4G cell, the terminal works in a 4G mode. If the traditional idle-state interoperation mechanism is adopted, the terminal measures 4G neighboring cells in all broadcast messages, triggers cell reselection when the reselection conditions are met, reads the broadcast message of the target cell and resides in the target cell. Similarly, there may be an SA network and an NSA network in 5G and an area where a 4G network overlaps, and after the terminal resides in an SA cell and a serving cell signal deteriorates, the terminal measures 4G neighboring cells in all broadcast messages according to a conventional inter-system idle state interoperation mechanism, and when a reselection condition is met, the terminal triggers cell reselection, reads a target cell broadcast message, and resides in the target cell.

In practical application, if the 4G neighboring cell is a neighboring cell supporting an NSA mode, after the terminal reselects a target cell, and after the current cell supports NSA, the working mode of the terminal is converted into the NSA mode, and a 5G network is adopted to carry service transmission; if the 4G neighboring cell is a neighboring cell which does not support the NSA mode, such as a 4G cell, and the terminal reselects the target cell, the terminal judges that the current cell does not support the NSA and still works in the 4G mode at the moment, and the 4G network is adopted to carry service transmission.

However, in the related art, in the process of performing cell reselection, the terminal may not distinguish the type of the 4G neighboring cell, that is, whether the type of the 4G neighboring cell is a cell supporting the NSA mode is not distinguished, then, for an NSA cell and a 4G cell overlapping coverage area, the terminal in the related art cannot preferentially select a neighboring cell supporting the NSA capability because the terminal cannot identify the type of the neighboring cell, so that the terminal cannot be converted into the NSA mode with a stronger transmission capability, but the terminal will always operate in the 4G mode, and then: the terminal can not carry out 5G service, and the user experience is reduced.

Based on this, in various embodiments of the present invention, a network device sends, to a terminal, indication information, where the indication information is used to indicate whether a type of a 4G neighboring cell corresponding to a serving cell covered by the network device is a cell supporting an NSA mode; and after receiving the indication information, the terminal can quickly determine the 4G adjacent cell with the prior measurement according to the indication information.

The following describes a process for implementing the method for determining a neighboring cell in the embodiment of the present invention with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart illustrating an implementation process of a method for determining a neighboring cell on a network device side according to an embodiment of the present invention, where the method for determining a neighboring cell is applicable to a network device, such as a base station, and as shown in fig. 1, the implementation process of the method for determining a neighboring cell according to an embodiment of the present invention may include the following steps:

step S101: the indication information is determined.

Here, the indication information is used to indicate whether the type of the 4G neighboring cell corresponding to the serving cell covered by the network device is a cell supporting the NSA mode. According to different services supported by a serving cell, the serving cell may be divided into a 4G cell, an NSA cell, and an SA cell.

Here, in actual application, the network device may determine the indication information according to needs, for example, the network device may be configured with the indication information in advance, which is not further limited in the embodiment of the present invention.

Step S102: and sending the indication information so that the terminal can determine the 4G adjacent region with the prior measurement based on the indication information.

In some embodiments, the sending the indication information includes:

setting the indication information in the adjacent cell information;

That is to say, the indication information is set in the neighbor cell information carried in the system message broadcast by the network device, so that, in actual application, the network device sends the indication information to the terminal in a full-network broadcast manner, so that the terminal determines the 4G neighbor cell to be preferentially measured based on the indication of the indication information.

In practical application, the neighboring cells corresponding to different types of serving cells may be different, and the frequency point information of different neighboring cells may also be different. Based on this, the neighboring cell information can be divided into same-frequency neighboring cell information and different-frequency neighboring cell information according to the difference of the frequency point information of the neighboring cells. That is, when the types of the serving cells are different, the indication information is set differently.

In some embodiments, when the serving cell is a 4G cell or an NSA cell, the setting the indication information in the neighboring cell information includes:

Here, in actual application, when the network device sends the indication information to the terminal, the network device may select to set the indication information in the same-frequency neighboring cell information of the system message according to the determined type of the serving cell, such as a 4G cell or an NSA cell. The same-frequency neighboring cell information may be, for example, a System message block of Type 4 (SIB4, System information block Type 4) in an Evolved Universal Mobile Telecommunications System (UMTS) terrestrial Radio Access Network (E-UTRAN), that is, the indication information is configured in an SIB4 (as shown in fig. 2).

In some embodiments, when the type of the serving cell is an independent networking SA cell, the setting the indication information in the neighboring cell information includes:

Here, in actual application, when the network device sends the indication information to the terminal, the network device may select to set the indication information in the inter-frequency neighboring cell information of the system message according to the determined type of the serving cell, such as the SA cell. The inter-frequency neighbor information may be, for example, a system message Block of Type 5 (SIB5, systeminformationblock Type 5) in the E-UTRAN, that is, the indication information is configured in an SIB5 (as shown in fig. 3).

Of course, for the type of the serving cell being a 4G cell or an NSA cell, the network device sets the indication information in SIB4 to indicate the type of the 4G neighboring cell corresponding to the serving cell.

In practical application, the indication method for the neighboring cell type may include:

Here, the neighboring cell information may specifically be same-frequency neighboring cell information, where the neighboring cell list includes all neighboring cells, that is, the indication information is set in each neighboring cell of the neighboring cell list included in the same-frequency neighboring cell information; the frequency point information list includes frequency point information of each neighboring cell, that is, the indication information is set in the frequency point information of each neighboring cell included in the same-frequency neighboring cell information.

In practical application, an indication bit sequence is set in the neighbor cell information, so that the effect of indicating the type of the 4G neighbor cell can be achieved through the indication of the indication bit sequence.

It should be noted that, for the type of the serving cell being an SA cell, the network device sets the indication information in SIB5, so as to indicate the type of the 4G neighboring cell corresponding to the serving cell. In practical application, the above-mentioned indication manner of the neighboring cell type (as shown in fig. 4) may be adopted when the serving cell type is a 4G cell or an NSA cell, and is not described herein again. The only difference is that, when the type of the serving cell is an SA cell, the corresponding neighboring cell information may specifically be inter-frequency neighboring cell information.

The method for determining the neighbor cell provided by the embodiment of the present invention can be used to distinguish whether the type of the 4G neighbor cell is a cell supporting the NSA mode through the indication of the indication information, so that when the terminal with the NSA capability performs cell reselection, the neighbor cell supporting the NSA mode is preferentially selected, and thus, the probability that the terminal operates in the NSA mode under the same condition can be increased, the terminal is prevented from operating in the 4G mode for a long time, and user experience is improved.

Correspondingly, fig. 5 is a schematic diagram of an implementation flow of a method for determining a neighboring cell at a terminal side according to an embodiment of the present invention, where the method for determining a neighboring cell is applicable to a terminal, such as a smart phone, and as shown in fig. 5, the implementation flow of the method for determining a neighboring cell according to an embodiment of the present invention may include the following steps:

step S501: indication information is received.

Here, the receiving indication information is actually the indication information sent by the network device for the terminal. The indication information is used for indicating whether the type of the 4G neighboring cell corresponding to the serving cell covered by the network device is a cell supporting the NSA mode.

Here, the network device may be, for example, a base station or the like. According to different services supported by a serving cell, the serving cell may be divided into a 4G cell, an NSA cell, and an SA cell.

In some embodiments, the receiving indication information includes:

That is, the terminal receives the indication information by receiving a broadcasted system message, wherein the indication information is set in the neighbor information of the system message.

In actual application, the manner of setting the indication information in the neighboring cell information is different according to different types of the serving cell. For example, the indication information may be set in the same-frequency neighboring cell information of the system message, and for another example, the indication information may be set in the different-frequency neighboring cell information of the system message.

It should be noted that the specific process of setting the indication information in the same-frequency neighboring cell information of the system message or setting the indication information in the different-frequency neighboring cell information of the system message is described in detail above, and is not described herein again.

Step S502: and determining the 4G adjacent regions which are measured preferentially based on the indication information.

In practical application, except that the indication information can be used for directly determining the 4G adjacent region with the priority measurement, the capability supported by the terminal can be taken into account, so that the two factors are combined to jointly determine the 4G adjacent region with the priority measurement, and the accuracy of determining the 4G adjacent region with the priority measurement can be improved.

Based on this, in some embodiments, the determining, based on the indication information, the 4G neighbor cell for preferential measurement includes:

Here, the terminal's own supported capabilities may include at least one of: support 4G mode, support NSA mode but not support SA mode, support SA mode and NSA mode simultaneously.

It should be noted that the embodiments of the present invention are not considered for terminals that support the SA mode but not the NSA mode.

In practical application, the terminal supports the NSA mode but not the SA mode, and when the cell where the terminal resides is the NSA cell, the terminal works in the NSA mode; and when the cell in which the terminal resides does not support the NSA capability, the terminal works in the 4G mode. The terminal simultaneously supports the SA mode and the NSA mode, and when the cell where the 5G terminal resides is a 5G NR cell, the terminal works in the SA mode; when the cell where the 5G terminal resides is an NSA cell, the terminal operates in an NSA mode; and when the cell where the 5G terminal resides does not support the NSA capability, the terminal works in the 4G mode.

Next, a specific implementation process of determining a preferentially measured 4G neighboring cell based on the indication information and the capabilities supported by the terminal itself will be described with respect to the several capabilities supported by the terminal itself described above.

In some embodiments, the capability supported by the terminal is to support only a 4G mode, and the determining a 4G neighboring cell to be preferentially measured based on the indication information and the capability supported by the terminal itself includes:

That is to say, when the capability supported by the terminal only supports the 4G mode, the types of the 4G neighboring cells corresponding to the serving cell covered by the network device are not distinguished, that is, the neighboring cell supporting the NSA mode and the neighboring cell supporting the 4G mode are not distinguished, and at this time, the neighboring cell supporting the NSA mode and the neighboring cell supporting the 4G mode are determined as the 4G neighboring cells with the same priority measurement. Therefore, in the process of measuring the adjacent cells, the terminal simultaneously measures the adjacent cells supporting the NSA mode and the adjacent cells supporting the 4G mode, and sorts all the adjacent cells according to a traditional cell reselection mechanism to select a target cell so as to reside in the target cell. This is not further limited by the examples of the present invention.

In some embodiments, the capability supported by the terminal is that the terminal supports an NSA mode but not an SA mode, and the determining a 4G neighboring cell that is measured preferentially based on the indication information and the capability supported by the terminal itself includes:

That is to say, when the capability supported by the terminal is that the terminal supports the NSA mode but does not support the SA mode, based on the indication of the indication information, it is determined that the type of the 4G neighbor cell corresponding to the serving cell covered by the network device is the neighbor cell that supports the NSA mode, and the terminal preferentially selects the neighbor cell that supports the NSA mode when the cell is reselected, so that the terminal is transitioned to the NSA mode with a stronger transmission capability, and the probability that the terminal operates in the NSA mode can be improved.

In some embodiments, the capability supported by the terminal is to support an SA mode and an NSA mode simultaneously, and the determining a 4G neighboring cell to be measured preferentially based on the indication information and the capability supported by the terminal itself includes:

That is to say, when the capability supported by the terminal is to support both the SA mode and the NSA mode, based on the indication of the indication information, it is determined that the type of the 4G neighbor cell corresponding to the serving cell covered by the network device is a neighbor cell that does not support the NSA mode.

In some embodiments, the method may further comprise:

measuring the 4G adjacent region which is preferentially measured;

and when the judgment result represents that the 4G adjacent cell which is measured preferentially does not meet the cell reselection condition, continuing to measure other adjacent cells in the 4G adjacent cell.

In practical application, when the 4G neighboring cell which is preferentially measured is determined to be a neighboring cell which supports the NSA mode, after a signal of a serving cell is degraded, when in-system neighboring cell measurement is performed, a terminal preferentially measures the neighboring cell which supports the NSA mode according to actual deployment of a network, and determines whether the neighboring cell which supports the NSA mode meets a set cell reselection condition, when the cell reselection condition is met, the terminal reselects from a currently resident serving cell and resides in a target neighboring cell which supports the NSA mode, where any one of the neighboring cells which support the NSA mode can be used as a target neighboring cell; and when the cell reselection condition is not met, the terminal will continue to measure other neighboring cells in the 4G neighboring cells, for example, the terminal will continue to measure a neighboring cell supporting the 4G mode in the 4G neighboring cells.

In actual application, when the 4G neighbor cell which is preferentially measured is determined to be the neighbor cell which supports the SA mode, after a signal of a service cell is degraded, when inter-system neighbor cell measurement is performed, a terminal preferentially measures the neighbor cell which supports the SA mode according to actual deployment of a network, judges whether the neighbor cell which supports the SA mode meets a set cell reselection condition, and when the cell reselection condition is met, the terminal reselects and resides in a target neighbor cell which supports the SA mode from a currently residing service cell, wherein any one of the neighbor cells which support the SA mode can be taken as the target neighbor cell; when the cell reselection condition is not met, the terminal continues to measure other adjacent cells in the 4G adjacent cells, for example, when the cell reselection condition is not met, the terminal preferentially measures the adjacent cell supporting the NSA mode, at this time, whether the adjacent cell supporting the NSA mode meets the cell reselection condition is judged, when the adjacent cell supporting the NSA mode meets the cell reselection condition, the inter-system cell is executed to reselect to a target adjacent cell supporting the NSA mode, and otherwise, the adjacent cell supporting the 4G mode in the 4G adjacent cells is measured.

It should be noted that, after determining the 4G neighboring cell for preferential measurement, when the signal of the serving cell deteriorates and the neighboring cell is measured, if none of the cells in the neighboring cell list satisfies the cell reselection condition and the serving cell cannot satisfy the camping condition, the terminal selects a target cell out of the neighboring cell list, and determines a procedure according to the existing cell type, that is, determines the type of the target cell according to the system message broadcast by the target cell, which is not described herein again.
