Technical field

The present disclosure relates to the field of communication technology, and in particular to a method, terminal and network equipment for cell reselection or handover.

Background technique

In related technologies, idle-state terminals measure signal strength and signal quality, and select the camping cell according to network broadcast thresholds, measurement configurations, and predefined criteria; the network sends measurement configurations to connected-state terminals, and the network receives measurement reports from the terminal The signal strength and signal quality of the cell are used for handover judgment, and the handover cell is selected for the terminal.

In the idle state, the network broadcasts the threshold and measurement configuration, so the behavior of all terminals in the cell is the same, but for some terminals with special capabilities, they may have special considerations for choosing a cell to camp on.

For example, some terminals that support multi-user identification card (Subscriber Identification Module, SIM) cards can support multiple SIM cards to work at the same time when they camp on the frequency band where cell 1 is located; On the frequency band, it is impossible to support multiple SIM cards to work at the same time. At this time, for this type of terminal, the use of the broadcast measurement configuration may cause the terminal to be unable to fully use its capabilities and reduce the system performance when the terminal is working.

For example, when the terminal supports both cellular mobile communication technology and WIFI technology, the frequency band used by the cellular system and the frequency band used by WIFI may cause serious harmonic and intermodulation interference in the device. When the interference is severe, it may cause A system is not working properly.

The connection state switching is also a similar problem. In related technologies, the network sends a measurement configuration to the terminal, and determines whether to switch based on the measurement results reported by the terminal. The main basis for switching is signal strength and signal quality, and from Factors such as frequency priority and load considered on the network side do not consider issues such as interference coexistence.

detailed description

Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the drawings show exemplary embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

As shown in FIG. 1, an embodiment of the present disclosure provides a method for cell reselection or handover, which is applied to a terminal, and the method includes:

Step 11: Detect the interference situation of the terminal.

Step 12: Perform cell reselection or handover according to the interference situation of the terminal.

In this embodiment of the present disclosure, the interference condition of the terminal is detected; and cell reselection or handover is performed according to the interference condition of the terminal. In this way, it is possible to select a better target cell according to the interference situation of the terminal.

In an optional embodiment of the present disclosure, if the terminal is in an idle state, detecting the interference of the terminal includes:

Step 111: Receive broadcast information sent by a network device, where the broadcast information includes at least one of the following: cell information or frequency information, camp threshold of each cell or frequency, and priority of the cell or frequency

Step 112: Detect the interference situation of the terminal.

Correspondingly, performing cell reselection according to the interference situation of the terminal includes:

Step 211: If the terminal has interference, increase the priority of the cell or frequency that does not cause the terminal to cause interference;

Step 212: Perform cell reselection according to the adjusted priority.

In an optional embodiment of the present disclosure, the method for cell reselection or handover may further include:

Step 13: The higher priority of the cell or frequency point without interference is adjusted to cover the priority of the cell or frequency point in the received broadcast information. It can be reselected to a cell with a higher priority during subsequent cell reselection.

In an optional embodiment of the present disclosure, performing cell reselection according to the interference situation of the terminal may further include:

If there is no interference in the cell or frequency where the terminal currently camps, reselect to the cell where the terminal currently camps.

The following describes an implementation process of the above-mentioned idle state terminal performing cell reselection, and the process includes:

Network equipment (such as base stations) broadcast cell selection and reselection related parameters, including frequency/cell information, camping threshold for each frequency/cell, frequency reselection priority, etc.;

The terminal receives the broadcast message of the base station and detects whether there is interference (harmonic/intermodulation interference). If there is coexistence interference, the terminal determines the frequency/cell that does not cause the terminal interference by detecting the coexistence interference. The priority is increased, and the increased priority will cover the reselection priority of the frequency broadcast by the original base station, and the terminal uses the updated frequency priority for cell reselection. Further, if a cell without coexistence interference meets the cell camping condition, reselect to the cell.

For example: the terminal is a terminal that supports multiple cards. When the SIM card 1 supported by the terminal works at frequency A and the SIM card 2 supported by the terminal works at frequency B, the terminal can work on two SIM cards at the same time; if the SIM card 1 When working at frequency point C, it cannot work on two SIM cards at the same time. The priority of the base station broadcast frequency point C is 7 (high priority), the priority of frequency point A is 1 (low priority), and the terminal will preferentially reside on frequency point C according to the procedures in the related technology. The terminal detects that coexistence interference occurs when it resides on C and B. There is no coexistence interference between B and A. To avoid coexistence interference, the terminal increases the priority of frequency A and preferentially resides on frequency A. The increased priority is used for cell reselection.

The terminal in the idle state of this embodiment detects coexistence interference and determines a cell/frequency without coexistence interference, which will increase the priority of the cell/frequency without coexistence interference for the terminal, and perform cell reselection according to the increased priority.

In an optional embodiment of the present disclosure, if the terminal is in a connected state, detecting the interference of the cell or frequency where the terminal is currently located includes:

Step 311: Receive a measurement configuration sent by a network device, where the measurement configuration includes at least one of the following: a measurement cell or a measurement frequency, a measurement threshold, and a measurement report event;

Step 312: Detect the interference situation of the terminal.

Correspondingly, performing cell handover according to the interference situation of the terminal includes:

Step 411: If the terminal has interference, obtain the measurement result of the cell or frequency that makes the terminal interference-free; and ignore the measurement threshold for enabling non-serving cell measurement;

Step 412: Send a first measurement result to the network device, where the first measurement result includes: a measurement result of a non-interfering cell or frequency;

Further, the method may further include: step 413, receiving a target cell fed back by the network device according to the first measurement result, and determining that the target cell is the cell to be handed over.

Optionally, if the first measurement result includes a measurement cell or measurement frequency in a non-measurement configuration, the first measurement result further includes: measurement cell or measurement frequency information in a non-measurement configuration and information about the non-measurement configuration. The identity of the measuring cell or the physical cell identity PCI; or, the indication information indicating the target cell to which the terminal expects to handover;

If the measurement configuration includes a measurement report event, and the measurement report event is that the terminal detects interference and can report a measurement result, the first measurement result further includes: a measurement cell or a measurement frequency in a non-measurement configuration.

The measurement of the measurement cell or measurement frequency point of the non-measurement configuration here is when the terminal detects interference and starts the measurement; or, according to the preset event configured by the network device, the measurement starts, the preset event is: terminal detection When interference is reached, start to measure the measurement cell or measurement frequency in the non-measurement configuration.

In another implementation, performing cell handover according to the interference situation of the terminal includes:

Step 511: If no interference occurs in the terminal and the serving cell satisfies the measurement threshold for enabling non-serving cell measurement, a second measurement result is obtained, and the non-serving cell is the measurement cell or the measurement cell in the measurement configuration. frequency;

Step 512: Send a second measurement result to the network device, where the second measurement result includes the measurement result of the non-serving cell.

Step 513: Receive a target cell fed back by the network device according to the second measurement result, and determine that the target cell is a cell to be handed over.

In an optional embodiment of the present disclosure, the method for cell reselection or handover may further include: receiving the configured blacklist cell or frequency sent by the network device, and not measuring the blacklist cell or frequency.

The following describes an implementation process of cell handover performed by the above-mentioned connected terminal, and the process includes:

The network equipment (such as the base station) sends the measurement configuration to the terminal, including the measurement frequency and the measurement threshold (used to enable the measurement of the non-serving cell, that is, the relevant parameter of the serving cell, such as the signal received power RSRP, exceeds the measurement threshold here. , The measurement of the non-serving cell is started), and the measurement report event (used to determine when to report the measurement result);

The terminal detects the situation of coexistence interference, and if no coexistence interference occurs and the current serving cell meets the threshold value for enabling non-serving cell measurement, the terminal starts measurement on the non-serving cell, and the non-serving cell belongs to the measurement frequency in the measurement configuration;

The terminal detects the coexistence interference situation. When coexistence interference occurs (assuming that the serving cell is in frequency A, frequency A will cause interference when the terminal and WiFi coexist), the terminal starts the measurement of the frequency/cell without coexistence interference, which can be ignored at this time Turn on the measurement threshold for the non-serving cell, and the non-serving cell is not limited to the measurement frequency in the measurement configuration;

In order to minimize the power consumption of the terminal and prevent the terminal from always searching and measuring the measurement frequency in the non-measurement configuration, a certain preset event trigger form can be used. The preset event can be implemented based on the terminal or based on the configuration of the base station, for example : Implementation based on the terminal: When the terminal detects coexistence interference (interference coexistence problem of multi-SIM card terminal, or interference coexistence problem in the device, etc.) or other problems that need to change the working frequency point, the terminal starts to measure non-serving cells and/or Measure the measurement frequency points in the non-measurement configuration. Based on the base station configuration: the base station adds the configuration of a preset event to the measurement configuration. For example, the preset event is: when the terminal detects coexistence interference, it starts to measure the non-serving cell and/or measures the measurement frequency in the non-measurement configuration.

If the measurement result includes a measurement frequency/cell in a non-measurement configuration, for such measurement results, the terminal needs to report: frequency information, cell ID or PCI, and measurement results at the same time; or,

The terminal may also report an indication information, which indicates the target cell that the terminal expects to handover, and this indication information may be reported together with the above measurement results; or,

If the network is configured with a measurement report event, and the measurement report event is "The terminal detects coexistence interference and can report measurement results", the terminal reports the measurement results after coexistence interference occurs. The measurement results here include (i) non-measurement configuration The measurement frequency/cell in can also include all measurement results.

The base station receives the measurement result reported by the terminal. If it receives the measurement result of the measurement frequency/cell in the measurement configuration other than the measurement configuration, it means that the terminal expects this cell to be the target cell for handover; or, if the base station receives the terminal’s instruction information, Indicates the target cell that the terminal expects to handover. The base station can select the target cell for handover for the terminal in combination with factors such as load and the target cell that the terminal expects to handover.

The base station configures the blacklist frequency for the terminal, and the terminal does not measure and/or report the frequency points in the blacklisted cell. The blacklist frequency may be certain dedicated frequencies, and ordinary terminals are not allowed to access; or the load of the blacklist frequency is too high to allow the terminal to access; or the signal level of the blacklist frequency is too low and the terminal accesses Produce interference.

In this embodiment, the connected terminal detects the coexistence interference of the current serving cell, determines the cell/frequency without coexistence interference, measures and reports the cell/frequency without coexistence interference, including frequency information, measurement results, cell ID/PCI, and triggers For handover, a better target cell can be selected according to the coexistence interference situation.

As shown in FIG. 2, the embodiment of the present disclosure also provides a method for cell reselection or handover, which is applied to a network device, and the method includes:

Step 21: Send broadcast information or measurement configuration to the terminal; the broadcast information is used for the terminal in the idle state to perform cell reselection according to the interference condition of the terminal, and the measurement configuration is used for the terminal in the connected state to perform cell handover according to the interference condition of the terminal .
