Description

Method for determining network type of neighbor cell and related equipment

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method for determining a neighbor network type and related devices.

Background

The high-speed railway network is a network deployed along a high-speed railway, and is specially optimized relative to a non-high-speed railway network (or public network) deployed around the high-speed railway so as to ensure the service experience of users in a high-speed moving state. For a User Equipment (UE) on a high-speed rail, in a case that the signal quality of a serving cell of the UE is poor, the UE may be handed over or rebuilt to an adjacent high-speed rail cell or a public network cell.

The reestablishment of the UE to the public network cell may cause interruption of data transmission and reception, and because the public network is not particularly optimized at high speed, the UE may cause poor user experience when operating in the public network cell. Therefore, in order to avoid the UE from reestablishing to the public network cell, whether the neighboring cell is a high-speed rail cell can be judged first.

Currently, after the measurement of the neighbor cell is completed, the UE needs to further decode the system information block (System Information Block, SIB) information of the neighbor cell to determine whether the neighbor cell is a high-speed rail cell. However, decoding SIB information may cause interruption of data transmission and reception of the UE in the serving cell, affecting user experience.

Detailed Description

In the description of the present application, "/" means "or" unless otherwise indicated, for example, a/B may mean a or B. The term "and/or" in this application is merely an association relation describing an association object, and means that three kinds of relations may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Furthermore, "at least one" may refer to one or more, and "a plurality" may refer to two or more. The "first", "second", etc. do not limit the number and order of execution, and the "first", "second", etc. do not necessarily differ.

In this application, the terms "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the description of the present application, "indication" may include direct indication and indirect indication, and may include display indication and implicit indication. Information indicated by a certain information (indication information described below) is called information to be indicated, and in a specific implementation process, there are various ways to indicate the information to be indicated. For example, the information to be indicated may be directly indicated, such as indicating the information to be indicated itself or an index of the information to be indicated. For another example, the information to be indicated may be indirectly indicated by indicating other information, where there is an association relationship between the indicated other information and the information to be indicated. For another example, only a portion of the information to be indicated may be indicated, while other portions of the information to be indicated are known or agreed in advance.

Technical terms and related technical knowledge that may be involved in the embodiments of the present application are described first. The terminology used in the description section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

(1) Target network and non-target network

The target network refers to a particular network that is specifically optimized for a particular user. The non-target network refers to a common network, or public network, adapted for public users.

For example, in a high-speed rail scenario, the target network refers to a high-speed rail network, and the non-target network refers to a non-high-speed rail network. The high-speed railway network is specially optimized for high-speed railway users to ensure the service experience of the high-speed railway users in a high-speed moving state.

Referring to fig. 1, fig. 1 is a schematic diagram of network deployment in a high-speed rail scenario according to an embodiment of the present application. As shown in fig. 1, two types of networks are included, one being a high-speed railway network 101 deployed along a high-speed railway, and the other being a non-high-speed railway network 102 deployed around the high-speed railway. There may be overlap in coverage areas of non-high-speed rail network 102 and high-speed rail network 101 such that User Equipment (UE) 103 on the high-speed rail may access cells under high-speed rail network 101 as well as cells under non-high-speed rail network 102.

(2) Cell measurement

The UE may perform cell measurement on the relevant neighbor cell of the serving cell according to a synchronization Signal block (Synchronization Signal Block, SSB) configured by the network side or measurement frequency point information of a channel state information-Reference Signal (CSI-RS), and report a measurement result to the network, where the network side indicates whether the UE performs cell handover according to the measurement result. The measurement results may include any one or more of reference signal received power (Reference Signal Received Power, RSRP), reference signal received quality (Reference Signal Received Quality, RSRQ), and signal-to-interference-and-noise ratio (Signal to Interference plus Noise Ratio, SINR), among others.

The measurements are classified into physical layer measurements (or L1 measurements) and radio resource control (Radio Resource Control, RRC) layer measurements (or L3 measurements). The measurement is divided into the same-frequency measurement, different-frequency measurement and different-system measurement. The embodiment of the application mainly performs the same-frequency measurement under the physical layer measurement, wherein the same-frequency measurement is defined as the same-frequency measurement based on the SSB or the CSI-RS, provided that the center frequency of the SSB or the CSI-RS of the measured service cell is the same as the center frequency of the SSB or the CSI-RS of the adjacent cell, and the subcarrier intervals of the SSB or the CSI-RS of the two cells are also the same.

If a Primary Cell (PCell) or a Primary secondary Cell (Primary Secondary Cell, PSCell) provides carrier frequency information, the UE should be able to identify a new co-frequency Cell even if an explicit neighbor list with a physical layer Cell identity is not provided. The identification of the new on-channel cell refers to that the UE obtains the physical cell identity (Physical Cell Identifier, PCI) by detecting the primary synchronization signal (Primary Synchronization Signal, PSS) or the secondary synchronization signal (Secondary Synchronization Signal, SSS), and the UE needs to perform PSS/SSS detection first to perform measurement. For SSB-based cell measurements, the UE performs SS-RSRP, SS-RSRQ, and SS-SINR measurements on the identified on-channel cells. For CSI-RS based cell measurements, the UE performs CSI-RSRP, CSI-RSRQ, and CSI-SINR measurements on the identified on-channel cells.

(3) Cell handover

Referring to fig. 2, fig. 2 is a schematic diagram of a cell handover according to an embodiment of the present application. As shown in fig. 2, cell 1 represents a serving Cell in which the UE is located, and Cell 2 represents a neighbor Cell detected by the UE. For a UE in a radio resource control (Radio Resource Control, RRC) connected state, when the signal quality of the serving Cell 1 gradually deteriorates (for example, RSRP becomes smaller) and the signal quality of the neighboring Cell 2 gradually increases (for example, RSRP becomes larger) with movement of the UE, in order not to interrupt the service, the network side switches the serving Cell of the UE from the Cell 1 with poor signal quality to the neighboring Cell 2 with good signal quality if the set condition is met.

The serving Cell 1 and the neighbor Cell 2 are on the same frequency point, the UE always performs the same frequency measurement, when the measurement result meets a certain condition (for example, an A3 event, that is, the signal quality of the neighbor Cell 2 is higher than that of the serving Cell 1 by a certain offset), the UE reports the measurement result to the network side, the network side generates a switching list to evaluate and judge the measurement result, and when the certain switching condition is met, the network side transmits a corresponding switching command to the UE.

(4) A3 event

The same-frequency switching can be triggered by an A3 event, wherein the A3 event means that the signal quality of the neighbor cell is higher than the signal quality of the serving cell by a certain Offset, wherein the signal quality can be described by RSRP, RSRQ or SINR, and the Offset can be configured by a higher layer and determined by a higher layer parameter (A3-Offset). This parameter is set for the A3 event for adjusting the ease of handoff. For example, the parameter may take a positive or negative value, which when taken increases the difficulty of triggering the A3 event, thereby facilitating delay of the handover; when taking the negative value, the difficulty of triggering the A3 event can be reduced, so that the early switching is facilitated.

(5) RRC reestablishment

The purpose of RRC reestablishment is to reestablish the RRC connection and reduce dropped calls. The RRC reestablishment procedure may be triggered by the following failure scenario:

Handover Failure: in the switching flow, after receiving a reconfiguration message containing a switching command, the UE starts a T304 timer, and if the UE cannot complete random access in a target cell before T304 times out, the UE initiates reestablishment with a cause value of "handover failure";

reconfiguration failure (Reconfiguration Failure): after receiving the reconfiguration message, the UE initiates a reestablishment with a cause value of reconfiguration failure if the reconfiguration message cannot be matched/compatible with the cells in the reconfiguration message in the security mode activation state;

other classes of failure scenarios include:

the UE may initiate a re-establishment request when the uplink radio link control (Radio Link Control, RLC) is re-communicated a maximum number of times;

the UE in the connected state may initiate random access in other scenarios except handover, such as resynchronization after out-of-sync, or the number of times of transmission of the scheduling request (Scheduling Request, SR) reaches the maximum number of times of retransmission, and if the random access fails, the UE may initiate a reestablishment request;

radio link failure (Radio Link Failure, RLF): in the physical layer, the UE continuously evaluates the RRC link quality between the neighboring cell and the serving cell, and reports the Block Error Rate (BLER) result of the evaluated physical downlink control channel (Physical Downlink Control Channel, PDCCH) to the RRC layer in a measurement configuration manner SINR Of radio link monitoring reference signal (Radio Link Monitoring-Reference Signals RLM-RS), estimating whether BLER Of current PDCCH is higher than Out-Of-Synchronization (OOS) threshold (BLER) according to SINR _out ) Or below the Synchronization (IS) threshold (BLER) _in ) Wherein the OOS threshold BLER _out And IS threshold BLER _in Depending on UE implementation, the RRC layer may count the number of OOS or IS continuously reported, and when it IS determined that the current RRC link quality IS particularly poor, the current connection cannot be maintained, and the power of the neighboring cell IS strong, the UE may trigger the RLF and RRC reestablishment procedure, and access to the neighboring cell through the RRC reestablishment procedure.

It is to be understood that the above definitions of the various technical terms are provided by way of example only. For example, as technology continues to evolve, the scope of the above definition may also change, and the embodiments of the present application are not limited.

Taking a high-speed rail scenario as an example for illustration, please refer to fig. 3, fig. 3 is a schematic diagram of cell switching and reconstruction in the high-speed rail scenario according to an embodiment of the present application. As shown in fig. 3, assuming that the UE on the high-speed rail operates in the serving cell, there are two physically co-frequency neighbors: one is a high-speed rail cell (the network type of which is a high-speed rail network) and the other is a public network cell (the network type of which is a non-high-speed rail network). And the UE performs the same-frequency measurement on the two cells, and if the measurement result of the Gao Tiexiao area does not meet the A3 event, the UE does not report the measurement result of the high-speed rail cell to the network side, namely the UE cannot be switched to the high-speed rail cell. Since the public network cell and the serving cell have no configuration neighbor cell relationship, the UE cannot be switched to the public network cell.

In some cases, for example: the power of the public network cell is stronger and weaker, the power of the service cell is lower and lower, the SINR of the service cell is lower and lower, the OOS reaches a certain number of times, or the uplink SR transmission number reaches the maximum retransmission number, or the random access fails, or the uplink congestion causes the uplink transmission failure, and the UE can be rebuilt to the public network cell through RRC before being switched to the high-speed rail cell. However, when the UE reestablishes to the public network cell, data transmission and reception are interrupted, and because the public network is not particularly optimized at high speed, a poor user experience may be caused when the UE works in the public network cell. Similarly, UEs that have access to the public network cell need to return to the high-speed rail cell through RRC reestablishment, which also results in interruption of data transmission and reception.

In order to ensure the experience of the high-speed rail user, the technical concept of the embodiment of the application comprises the following steps: the UE knows whether the neighboring cell is a high-speed railway cell or not in advance, so that the UE is prevented from being rebuilt to the public network cell, the UE can continuously transmit and receive data in the high-speed railway cell as much as possible, or the UE which is resident in the public network cell can return to the high-speed railway cell as soon as possible, and the UE is prevented from being in the public network cell for a long time.

At present, the scheme for judging whether the neighbor cell is a high-speed railway cell is as follows: after the UE completes the neighbor cell measurement, whether the neighbor cell is a high-speed rail cell or not is judged by further decoding system information block (System Information Block, SIB) information of the neighbor cell. Specifically, if a high-speed configuration parameter (high speed configuration) is configured in SIB1 information of a neighboring cell, the neighboring cell is a high-speed railway cell; if the high-speed configuration parameter is not configured in the SIB1 information of the neighbor cell, the neighbor cell is a non-high-speed railway cell. The SIB1 information is carried in a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH). However, the above solution requires the UE to further decode SIB1 information after completing neighbor cell measurement, which may cause interruption of data transmission and reception of the UE in the serving cell, and affect user experience.

In order to solve the above problems, the embodiments of the present application provide a method for determining a network type of a neighboring cell and related devices, which can avoid interruption of data transmission and reception of a user equipment in a serving cell, and are beneficial to improving user experience.

In order to better understand a method for determining a network type of a neighboring cell provided in the embodiments of the present application, an example of a network architecture applicable to the embodiments of the present application is described below.

In combination with the above network architecture, a method for determining a network type of a neighboring cell according to an embodiment of the present application is described below. Referring to fig. 5, fig. 5 is a flowchart of a method for determining a network type of a neighboring cell according to an embodiment of the present application, and the method may be applied to the ue 403 in the network architecture shown in fig. 4. As shown in fig. 5, the method of determining a neighbor network type may include the following steps S501 to S503.

S501: and carrying out neighbor cell detection on the service cell where the user equipment is located, and obtaining neighbor cell identifiers.

The serving cell where the ue is located may be understood as a cell to which the ue is currently connected, and a network device corresponding to the serving cell may be preconfigured with a measurement object, for example, a frequency measurement frequency point, and the ue may perform neighbor detection, for example, perform Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) detection, according to the configured same frequency measurement frequency point, so as to obtain a neighbor identifier.

The neighbor cell identifiers are used for indicating detected neighbor cells, one neighbor cell identifier indicates one neighbor cell, and different neighbor cell identifiers indicate different neighbor cells. The neighbor cell identifier may be represented by a Physical Cell Identifier (PCI), or may be represented by other identifiers, for example, an identifier having a correspondence with the PCI, where the correspondence may be, but is not limited to, an association or a conversion relationship.

S502: a set of cell identities is obtained.

A set of cell identities is understood to be a set of a plurality of cell identities, one cell identity indicating one cell and different cell identities indicating different cells. The cell identifier herein may be represented by a Physical Cell Identifier (PCI), or may be represented by other identifiers, for example, an identifier having a correspondence with the PCI, where the correspondence may be, but is not limited to, an association or a conversion.

The network type of the cell indicated by each cell identity in the set of cell identities is determined, and the network type of the cell indicated by each cell identity may be one of a target network and a non-target network.

S503: and determining whether the network type of the neighbor cell indicated by the neighbor cell identifier is a target network according to the neighbor cell identifier and the cell identifier set.

According to the neighbor cell identification and the cell identification set, whether the cell identification matched with the neighbor cell identification exists in the cell identification set or not can be determined, and then whether the network type of the neighbor cell indicated by the neighbor cell identification is a target network or not is determined according to whether the network type of the cell indicated by the cell identification is a target network or not. The neighbor cell identifier is matched with the cell identifier, which can be understood as that the neighbor cell indicated by the neighbor cell identifier and the cell indicated by the cell identifier are the same cell.

In one possible implementation manner, the neighbor cell identifier and the cell identifier are expressed in the same form, for example, are both expressed by using PCI, and at this time, whether the cell identifier matched with the neighbor cell identifier exists in the cell identifier set can be determined by judging whether the cell identifier identical with the neighbor cell identifier exists in the cell identifier set. Specifically, if the cell identifier set has the same cell identifier as the neighbor cell identifier, determining that the cell identifier set has the cell identifier matched with the neighbor cell identifier, where the cell identifier matched with the neighbor cell identifier is the same cell identifier as the neighbor cell identifier.

In another possible implementation manner, the neighbor cell identifier and the cell identifier are expressed in different forms, for example, the neighbor cell identifier is expressed by using a PCI, and the cell identifier is expressed by using an identifier having an association relationship with the PCI, and at this time, whether the cell identifier matched with the neighbor cell identifier exists in the cell identifier set can be determined by judging whether the cell identifier associated with the neighbor cell identifier exists in the cell identifier set. Specifically, if the cell identifier associated with the adjacent cell identifier exists in the cell identifier set, determining that the cell identifier matched with the adjacent cell identifier exists in the cell identifier set, wherein the cell identifier matched with the adjacent cell identifier is the cell identifier associated with the adjacent cell identifier.

In another possible implementation manner, the neighbor cell identifier and the cell identifier are expressed in different forms, for example, the neighbor cell identifier is expressed by using a PCI, and the cell identifier is expressed by using an identifier having a conversion relationship with the PCI, at this time, the neighbor cell identifier may be converted correspondingly to obtain a converted identifier, and then, whether the cell identifier matched with the neighbor cell identifier exists in the cell identifier set is determined by judging whether the cell identifier identical with the converted identifier exists in the cell identifier set. Specifically, if the cell identifier set has the same cell identifier as the converted identifier, determining that the cell identifier set has the cell identifier matched with the neighbor cell identifier, where the cell identifier matched with the neighbor cell identifier is the same cell identifier as the converted identifier.

In the case that the cell identifier matched with the neighbor cell identifier exists in the cell identifier set, whether the network type of the neighbor cell indicated by the neighbor cell identifier is a target network can be determined according to whether the network type of the cell indicated by the neighbor cell identifier is the target network or not. Specifically, if the cell identifier matched with the neighbor cell identifier is the target network, determining the network type of the neighbor cell indicated by the neighbor cell identifier as the target network; if the cell identifier matched with the neighbor cell identifier is the non-target network, determining that the network type of the neighbor cell indicated by the neighbor cell identifier is the non-target network.

Optionally, the network type of the cell indicated by each cell identity in the set of cell identities is the same. For example, the network types of the cells indicated by the cell identities in the set of cell identities are all target networks. In this case, if there is a cell identifier matching with the neighbor cell identifier in the cell identifier set, determining the network type of the neighbor cell indicated by the neighbor cell identifier as the target network; if the cell identifier matched with the neighbor cell identifier does not exist in the cell identifier set, determining that the network type of the neighbor cell indicated by the neighbor cell identifier is a non-target network.

For another example, the network types of the cells indicated by the cell identities in the set of cell identities are all non-target networks. In this case, if there is a cell identifier matching with the neighbor cell identifier in the cell identifier set, determining that the network type of the neighbor cell indicated by the neighbor cell identifier is a non-target network; if the cell identifier matched with the neighbor cell identifier does not exist in the cell identifier set, determining the network type of the neighbor cell indicated by the neighbor cell identifier as a target network.

Optionally, the cell identifier set includes a first cell identifier set and a second cell identifier set, where the network types of the cells indicated by each cell identifier in the first cell identifier set are the same and are all target networks; the network types of the cells indicated by the cell identifiers in the second cell identifier set are the same, and the cells are non-target networks. In this case, if there is a cell identifier matched with the neighbor cell identifier in the first cell identifier set, determining the network type of the neighbor cell indicated by the neighbor cell identifier as a target network; if the second cell identifier set has the cell identifier matched with the adjacent cell identifier, determining that the network type of the adjacent cell indicated by the adjacent cell identifier is a non-target network.

In the scheme provided by the embodiment, after the user equipment obtains the neighbor cell identifier, whether the network type of the neighbor cell is the target network can be determined according to the neighbor cell identifier and the cell identifier set, and neighbor cell measurement is not required in the determination process, and system information block information of the neighbor cell is not required to be further decoded, so that interruption of data receiving and transmitting of the user equipment in the service cell can be avoided, and the user experience is facilitated.

In combination with the foregoing embodiments, another method for determining a neighboring cell network type provided in the embodiments of the present application is described below. It should be understood that the terms used in the various embodiments may be mutually referenced, and the same terms may not be repeated for the different embodiments to avoid redundancy in description. Referring to fig. 6, fig. 6 is a flowchart of another method for determining a neighboring cell network type according to an embodiment of the present application. As shown in fig. 6, the method of determining a neighbor network type may include the following steps S601 to S607. Among them, S604 to S607 are optional steps. It should be understood that, for the specific description of step S601, reference may be made to step S501, which is not repeated herein.

S601: and carrying out neighbor cell detection on the service cell where the user equipment is located, and obtaining neighbor cell identifiers.

S602: and receiving signaling sent by network equipment corresponding to the service cell, wherein the signaling comprises a cell identification set.

When the user equipment accesses the serving cell, for example, when the user equipment is just connected with the network equipment, the network equipment transmits signaling to the user equipment, wherein the signaling comprises a cell identification set. The user equipment, upon receiving the signaling, then obtains a set of cell identities.

In the scheme, the signaling sent by the network equipment to the user equipment comprises the cell identification set, and the user equipment can obtain the cell identification set by receiving the signaling, so that the obtaining difficulty is low.

Optionally, after obtaining the cell identifier set, the user equipment further determines a network type of the cell identifier set, where the network type of the cell identifier set refers to a network type of a cell indicated by a cell identifier in the cell identifier set. The network type of the set of cell identities may be one of a target network and a non-target network.

A possible implementation manner determines, according to a network type of a serving cell, that a cell identifier set is one of a first cell identifier set and a second cell identifier set, where a network type of a cell indicated by a cell identifier in the first cell identifier set is a target network, and a network type of a cell indicated by a cell identifier in the second cell identifier set is a non-target network.

When the user equipment accesses to the service cell, the network type of the service cell can be obtained. The network type of the cell identification set issued by the network equipment is the same as the network type of the service cell. The user equipment may thus determine the network type of the set of cell identities based on the network type of the serving cell.

Specifically, if the network type of the serving cell is a target network, determining that the cell identifier set is a first cell identifier set; if the network type of the serving cell is a non-target network, determining the cell identification set as a second cell identification set.

It can be understood that if the network type of the serving cell is the target network, the network type of the cell identifier set is also the target network, and the cell identifier set is the first cell identifier set. If the network type of the serving cell is a non-target network, the network type of the cell identifier set is also a non-target network, and the cell identifier set is a second cell identifier set.

In one possible implementation manner, the signaling further includes network indication information associated with the cell identification set, and according to the network indication information, it is determined that the cell identification set is one of a first cell identification set and a second cell identification set, where a network type of a cell indicated by a cell identification in the first cell identification set is a target network, and a network type of a cell indicated by a cell identification in the second cell identification set is a non-target network.

Network indication information associated with the cell identification set is used for indicating the network type of the cell identification set. After receiving the signaling, the user equipment obtains the cell identification set and the associated network indication information thereof, and then determines the network type of the cell identification set according to the network type indicated by the network indication information.

Specifically, if the network indication information indicates the target network, determining the cell identifier set as a first cell identifier set; and if the network indication information indicates a non-target network, determining the cell identification set as a second cell identification set.

It may be appreciated that if the network indication information indicates the target network, the network type of the cell identity set is the target network, and the cell identity set is the first cell identity set. If the network indication information indicates a non-target network, the network type of the cell identification set is the non-target network, and the cell identification set is a second cell identification set.

S603: and determining whether the network type of the neighbor cell indicated by the neighbor cell identifier is a target network according to the neighbor cell identifier and the cell identifier set.

In a possible implementation manner, if the cell identifier set is a first cell identifier set, determining that the network type of the neighbor cell indicated by the neighbor cell identifier is a target network if the neighbor cell identifier is in the first cell identifier set; if the neighbor cell identifier is not in the first cell identifier set, determining that the network type of the neighbor cell indicated by the neighbor cell identifier is a non-target network.

Whether the neighbor cell identity is in the first set of cell identities may be determined by determining whether the neighbor cell identity is the same as the cell identities in the first set of cell identities. Specifically, if the neighbor cell identifier is the same as one cell identifier in the first cell identifier set, determining that the neighbor cell identifier is in the first cell identifier set; if the neighbor cell identifier is different from all the cell identifiers in the first cell identifier set, determining that the neighbor cell identifier is not in the first cell identifier set.

Whether the neighbor cell identifier is in the first cell identifier set can also be determined by judging whether the correspondence exists between the neighbor cell identifier and the cell identifiers in the first cell identifier set. The neighbor cell identifier and the cell identifier have a corresponding relationship, which can be understood that the neighbor cell indicated by the neighbor cell identifier and the cell indicated by the cell identifier are the same cell. Specifically, if a corresponding relation exists between the neighbor cell identifier and one cell identifier in the first cell identifier set, determining that the neighbor cell identifier is in the first cell identifier set; and if the corresponding relation does not exist between the adjacent cell identifier and all the cell identifiers in the first cell identifier set, determining that the adjacent cell identifier is not in the first cell identifier set.

In another possible implementation manner, if the cell identifier set is the second cell identifier set, if the neighbor cell identifier is in the second cell identifier set, determining that the network type of the neighbor cell indicated by the neighbor cell identifier is a non-target network; if the neighbor cell identifier is not in the second cell identifier set, determining the network type of the neighbor cell indicated by the neighbor cell identifier as a target network.

Whether the neighbor cell identity is in the second set of cell identities may be determined by determining whether the neighbor cell identity is the same as the cell identities in the second set of cell identities. Specifically, if the neighbor cell identifier is the same as one cell identifier in the second cell identifier set, determining that the neighbor cell identifier is in the second cell identifier set; if the neighbor cell identifier is different from all the cell identifiers in the second cell identifier set, determining that the neighbor cell identifier is not in the second cell identifier set.

Whether the neighbor cell identifier is in the second cell identifier set can also be determined by judging whether the correspondence exists between the neighbor cell identifier and the cell identifiers in the second cell identifier set. The neighbor cell identifier and the cell identifier have a corresponding relationship, which can be understood that the neighbor cell indicated by the neighbor cell identifier and the cell indicated by the cell identifier are the same cell. Specifically, if a corresponding relation exists between the neighbor cell identifier and one cell identifier in the second cell identifier set, determining that the neighbor cell identifier is in the second cell identifier set; and if the corresponding relation does not exist between the adjacent cell identifier and all the cell identifiers in the second cell identifier set, determining that the adjacent cell identifier is not in the second cell identifier set.

Alternatively, in the case where the network type of the neighbor cell is determined to be a non-target network, step S604 is performed.

S604: no reselection, no handover or no reestablishment to the neighbor cell.

The network type of the neighbor cell is a non-target network, which indicates that the neighbor cell is not a cell which the user equipment desires to access, and the neighbor cell is not selected as a target cell no matter whether the network type of the serving cell is a target network or a non-target network, namely, the neighbor cell is not reselected, switched or rebuilt.

For example, the network type of the serving cell is a target network, one or more operations of measuring the neighbor cell and reselecting or reestablishing to the neighbor cell according to the measurement result of the neighbor cell may be skipped, thereby avoiding reselection or reestablishing to the neighbor cell.

For another example, the network type of the serving cell is a non-target network, and one or more operations of measuring the neighbor cell, reporting the measurement result of the neighbor cell to the network device, and responding to a handover instruction of the network device may be skipped, so as to avoid handover to the neighbor cell; one or more operations of measuring the neighbor cell and reselecting or reconstructing the neighbor cell according to the measurement result of the neighbor cell may also be skipped, thereby avoiding reselection or reconstruction to the neighbor cell.

In the above scheme, under the condition that the network type of the neighbor cell is a non-target network, the user equipment does not reselect, switch or reestablish the neighbor cell, so that the influence on the data receiving and transmitting of the user equipment in the process of reselecting, switching or reestablishing the neighbor cell of the non-target network can be reduced, and the user experience is prevented from being deteriorated.

Alternatively, in the case where the network type of the neighbor cell is determined as the target network, step S605 is performed.

S605: and judging whether the network type of the serving cell is a target network.

Alternatively, in the case where the network type of the serving cell is the target network, step S606 is performed.

S606: and when the preset condition is met, reporting the measurement result of the neighbor cell to the network equipment corresponding to the service cell.

After determining that the network type of the neighbor cell is the target network, the user equipment may measure the neighbor cell to obtain a measurement result of the neighbor cell, where the measurement result may characterize the signal quality of the neighbor cell, for example, the measurement result may be, but not limited to, RSRP, RSRQ, or SINR.

In the case that the network type of the serving cell is the target network, the ue may determine whether a preset condition is satisfied based on the measurement result of the neighbor cell, where the preset condition may be a condition corresponding to the signal quality of the neighbor cell, for example, an A3 event. When the preset condition is met, the user equipment reports the measurement result of the neighbor cell to the network equipment corresponding to the service cell, and the network equipment indicates whether the user equipment performs cell switching or not through certain judgment.

In the above scheme, under the condition that the network types of the neighbor cell and the service cell are both target networks, the user equipment can be switched to the target network neighbor cell according to the preset condition, which is beneficial to keeping stable work in the target network.

Alternatively, in the case where the network type of the serving cell is a non-target network, step S607 is performed.

S607: reconstructing the neighbor cell according to the measurement result of the neighbor cell.

In case that the network type of the serving cell is a non-target network, the user equipment may reestablish to the neighbor cell through RRC according to the measurement result of the neighbor cell.

In the above scheme, the user equipment can reconstruct to the target network neighbor cell under the condition that the network type of the neighbor cell is the target network and the network type of the service cell is the non-target network, which is beneficial to improving the user experience.

S701: and carrying out neighbor cell detection on the service cell where the user equipment is located, and obtaining neighbor cell identifiers.

S702: a predefined or pre-stored set of cell identities is read.

The cell identification set may be predefined in the protocol, or may be pre-stored in the ue, and the ue obtains the cell identification set by reading the predefined or pre-stored information.

The cell identifiers may be divided into two types in advance, where the two types of cell identifiers respectively form a first cell identifier set and a second cell identifier set, where the network type of the cell indicated by the cell identifier in the first cell identifier set is a target network, and the network type of the cell indicated by the cell identifier in the second cell identifier set is a non-target network.

Optionally, the set of cell identities is in particular a first set of cell identities. Optionally, the set of cell identities is in particular a second set of cell identities. Optionally, the set of cell identities comprises a first set of cell identities and a second set of cell identities.

In the scheme, the user can obtain the cell identification set by reading the predefined or prestored information, the acquisition efficiency is high, the additional signaling overhead is not needed, and the network resources are saved.

Alternatively, the network type may be indicated by MIB information without increasing information bits, for example, by 1-bit information reserved in MIB information. The network type indicated by the MIB information may be one of a target network and a non-target network, and whether the network type of the neighbor cell is the target network may be determined according to the network type indicated by the MIB information.

Specifically, if the MIB information indicates the target network, determining the network type of the neighbor cell as the target network; if the MIB information indicates a non-target network, determining the network type of the neighbor cell as the non-target network.

In the scheme provided by the embodiment, the user equipment determines whether the network type of the neighbor cell is the target network according to the MIB information of the neighbor cell, and only the MIB information of the neighbor cell is needed to be decoded in the determining process, and SIB information of the neighbor cell is not needed to be further decoded, so that interruption of data receiving and transmitting of the user equipment in the service cell can be avoided, and the user experience is facilitated.
