Technical Field

The application belongs to the technical field of communication, and particularly relates to a voice fallback method, a voice fallback device and user equipment.

Background

In cellular systems, the associated protocols provide for using the previous generation network to carry voice traffic if the new generation network has insufficient voice carrying capability, for example, from a fifth generation wireless communication (5-generation, 5G) independent networking (SA) voice fallback to a fourth generation wireless communication (4-generation, 4G).

When a User Equipment (UE) initiates a voice call request or receives a voice call request, a network device issues measurement control To the UE, where a report configuration List (report To Add Mod List) in the measurement control carries a Reference Signal Received Power (RSRP) threshold. If the UE reports according to the RSRP threshold measurement, the UE may report a cell with a poor signal quality value, so that the UE fails to access the cell or a radio link error occurs after the UE accesses the cell, and further voice fallback failure is caused.

In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The embodiment of the application provides a voice fallback method, a voice fallback device and UE (user equipment). under the condition that the UE is a calling party or a called party, a first frequency point can be measured according to measurement control information sent by network equipment; and sending a measurement report of the first cell to the network equipment under the condition that the signal quality value of the first cell corresponding to the first frequency point is greater than a preset threshold value, wherein the preset threshold value is configured by the UE; and accessing the first cell according to the indication information sent by the network equipment, and establishing the voice fallback conversation in the first cell. By the scheme, the preset threshold is configured for the UE, for example, the UE can configure different preset thresholds under the condition that the maturity of the cell is different, so that the UE reports the measurement report not under the condition that the RSRP threshold in the measurement control issued by the network device is met, but reports the measurement report of the cell with better quality as much as possible, thereby improving the success rate of voice fallback.

The following describes in detail a voice fallback method, an apparatus and a UE provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present application provides a voice fallback method. The method may include S101 to S103 described below. The method is exemplified below by taking the execution subject as the UE.

S101, under the condition that the UE is called or called, the UE measures a first frequency point according to measurement control information sent by network equipment.

The application provides the following two scenarios as application scenarios of the voice fallback method:

one scenario is that when the UE is used as a calling device and initiates a call to a called device, a network device in communication connection with both the calling device and the called device issues measurement control information to the calling device; in another scenario, when the UE is used as a called device and receives a called instruction sent by the calling device, the network device communicatively connected to both the calling device and the called device issues measurement control information to the calling device.

For example, after the UE is powered on, the UE may camp on the 5G SA and register with a voice over long term evolution (VoLTE) based voice system, so that the UE may initiate a call (i.e., make a call) to another device or receive a called command (i.e., answer a call) from another device. And then, the network equipment can send the measurement control information to the UE, so that the UE can measure the first frequency point according to the measurement control information.

Optionally, the measurement control information may include at least one of:

measurement Object list meas Object To Add ModList,

Reporting a report configuration List report To Add Mod List,

Measurement report configuration List meas Id To Add Mod List.

The measurement object list may be used to indicate a cell frequency point of a cell to be measured.

The reporting event configuration list may be used to indicate LTE B1 event configuration, where the LTE B1 event configuration includes a RSRP threshold (threshold), and generally, the RSRP threshold is low, and if the UE reports according to the RSRP threshold measurement, the UE may report a cell with a poor signal quality value, so that the UE fails to access the cell or a radio link error occurs after accessing the cell, and further voice fallback fails, so the RSRP threshold in the LTE B1 event configuration is not used in the present application.

The measurement report configuration list may be used to indicate measurement objects and reporting events.

Optionally, the frequency points of the cells in the measurement object list may be arranged according to a preset priority, for example, the frequency point of the cell with the highest UE access frequency is set to be the highest priority, and the frequency point of the cell with the lowest UE access frequency is set to be the lowest priority. Of course, the priority ranking order of the frequency points of each cell may also be set in other manners, and this embodiment of the present application is not limited.

For example, the first frequency point is taken as the cell with the highest priority in the measurement object list. After the UE receives measurement control information sent by the network device to the UE, if a measurement object list included in the measurement control information indicates that the priority of the first frequency point is the highest, the UE may measure the first frequency point.

S102, when the signal quality value of a first cell corresponding to the first frequency point is larger than a preset threshold value, the UE sends a measurement report of the first cell to the network equipment.

Wherein, the preset threshold is configured by the UE. For example, the preset threshold may be configured by the UE according to the maturity of the cell.

Regarding "the signal quality value of the first cell corresponding to the first frequency point is equal to the preset threshold value", the embodiment of the present application provides two optional implementation manners as follows:

a first optional implementation manner is that the UE may send a measurement report of a first cell to the network device when the signal quality value of the first cell corresponding to the first frequency point is equal to a preset threshold.

Specifically, if the signal quality value of the first cell corresponding to the first frequency point is greater than or equal to the preset threshold, the signal quality of the first cell corresponding to the first frequency point may be considered to be better, so that the UE may send a measurement report of the first cell to the network device; and if the signal quality value of the first cell corresponding to the first frequency point is smaller than the preset threshold value, the signal quality of the first cell corresponding to the first frequency point can be considered to be poor, so that the UE does not send the measurement report of the first cell to the network device.

A second optional implementation manner is that the UE may not send the measurement report of the first cell to the network device when the signal quality value of the first cell corresponding to the first frequency point is equal to the preset threshold.

Specifically, if the signal quality value of the first cell corresponding to the first frequency point is greater than the preset threshold, the signal quality of the first cell corresponding to the first frequency point may be considered to be better, so that the UE may send a measurement report of the first cell to the network device; and if the signal quality value of the first cell corresponding to the first frequency point is less than or equal to the preset threshold, the signal quality of the first cell corresponding to the first frequency point can be considered to be poor, so that the UE does not send the measurement report of the first cell to the network device.

The following embodiments are all described by taking the first optional implementation manner as an example, and do not limit the embodiments of the present application. In practical implementation, the second optional implementation manner may also be adopted to implement the voice fallback method in the embodiment of the present application.

Optionally, the preset threshold configured by the UE may include at least two of a preset RSRP, a preset RSRQ, and a preset SINR. Correspondingly, the signal quality value of the first cell corresponding to the first frequency point is greater than the preset threshold value, and includes at least two items:

(1) the reference RSRP of the first cell is greater than a preset RSRP.

(2) The Reference Signal Received Quality (RSRQ) of the first cell is greater than a preset RSRQ.

(3) The signal-to-interference and noise ratio (SINR) of the first cell is greater than a predetermined SINR.

Optionally, the measurement report of one cell includes: physical Cell Identity (PCI) of one cell, signal quality value of one cell. Wherein the PCI of the one cell may be used to indicate the one cell.

Optionally, the measurement control information may be used to indicate multiple frequency points, where each frequency point corresponds to at least one cell, that is, the frequency point of at least one cell may be the same frequency point of the multiple frequency points. For example, taking the first cell PCI 1 and the second cell PCI 2 corresponding to the first frequency point as an example, if the signal quality value of the first cell corresponding to the first frequency point is greater than a preset threshold value, and the signal quality value of the second cell corresponding to the first frequency point is less than or equal to the preset threshold value, the UE may only send the measurement report of the first cell to the network device.

S103, the UE accesses the first cell according to the indication information sent by the network equipment and establishes the voice fallback conversation in the first cell.

In this embodiment of the application, if the UE-camped network is the first network under the condition that the UE is the calling or the called, after the UE sends the measurement report of the first cell to the network device, the network device may send indication information to the UE, where the indication information may be used to indicate that the UE is allowed to access the first cell. After the UE successfully accesses the first cell according to the indication information sent by the network device, the UE may establish a voice fallback session in the first cell. The network of the first cell is a second network, and the network system of the second network is lower than that of the first network. Thus, the UE implements voice fallback.

For example, assuming that the first network is a 5G SA and the second network is LTE, the UE falls back from 5G SA voice to LTE voice, i.e. an evolved packet system (EPS fallback) mechanism is adopted.

For another example, assuming that the first network is 4G, the second network is 3G or 2G, and the UE falls back from 4G voice to 3G or 2G voice, that is, a circuit switched fallback (CS fallback) mechanism is adopted.

The embodiment of the application provides a voice fallback method, which can measure a first frequency point according to measurement control information sent by network equipment under the condition of a UE calling party or a UE called party; and sending a measurement report of the first cell to the network equipment under the condition that the signal quality value of the first cell corresponding to the first frequency point is greater than a preset threshold value, wherein the preset threshold value is configured by the UE; and accessing the first cell according to the indication information sent by the network equipment, and establishing the voice fallback conversation in the first cell. By the scheme, the preset threshold is configured for the UE, for example, the UE can configure different preset thresholds under the condition that the maturity of the cell is different, so that the UE reports the measurement report not under the condition that the RSRP threshold in the measurement control issued by the network device is met, but reports the measurement report of the cell with better quality as much as possible, thereby improving the success rate of voice fallback.

Alternatively, in conjunction with fig. 1, as shown in fig. 2, the above S101 may be implemented by S101A described below. Accordingly, S102 described above can be implemented by S102A described below.

S101A, under the condition that the UE is called or called, the UE receives the measurement control information sent by the network equipment, measures the first frequency point according to the measurement control information sent by the network equipment, and starts timing.

It should be noted that, in the embodiment of the present application, the execution sequence of "measuring the first frequency point according to the measurement control information sent by the network device" and "starting timing" is not specifically limited, and may be determined according to the actual use requirement. For example, the UE may simultaneously perform "measure the first frequency point according to the measurement control information sent by the network device" and "start timing"; or "measure the first frequency point according to the measurement control information sent by the network device" may be executed first, and then "start timing" may be executed; and the 'starting timing' can be executed firstly, and then the 'measuring the first frequency point according to the measuring control information sent by the network equipment' is executed.

S104, the UE determines whether the timing time reaches a preset time length.

When the UE determines that the timing time does not reach the preset duration, the UE may perform S105 described below; in a case where the UE determines that the counted time reaches the preset time period, the UE may perform S109 described below.

Optionally, the preset time duration may be configured, or preconfigured, or protocol-specified, or configured by the network device, or preconfigured by the network device, and this embodiment of the present application is not limited.

S105, the UE determines whether the signal quality value of the first cell corresponding to the first frequency point is larger than a preset threshold value.

When the UE determines that the timing time does not reach the preset duration, the UE may determine whether a signal quality value of a first cell corresponding to the measured first frequency point is greater than a preset threshold configured by the UE, for example, determine whether an RSRP of the first cell is greater than a preset RSRP, and determine whether an RSRQ of the first cell is greater than a preset RSRQ. When the UE determines that the signal quality value of the first cell corresponding to the first frequency point is greater than the preset threshold, the UE may perform S102A described below; in a case that the UE determines that the signal quality value of the first cell corresponding to the first frequency point is less than or equal to the preset threshold, the UE may perform S106 described below.

S102A, when the timing time does not reach the preset time length and the signal quality value of the first cell corresponding to the first frequency point is greater than the preset threshold value, the UE sends the measurement report of the first cell to the network equipment and stops timing.

According to the voice fallback method provided by the embodiment of the application, before the timing duration of the UE reaches the preset duration, if the signal quality value of the first cell corresponding to the first frequency point is greater than the preset threshold, the UE sends the measurement report of the first cell to the network device, so that the network device can obtain the measurement report of the cell with better quality, and the UE can fall back to the cell through voice.

Further, as shown in fig. 2, after S105, the speech fallback method provided in the embodiment of the present application may further include S106 described below. Further, after S106, S107 or S108 described below may be further included.

And S106, under the condition that the timing time does not reach the preset duration and the signal quality value of the first cell corresponding to the first frequency point is less than or equal to the preset threshold value, the UE measures the second frequency point according to the measurement control information.

Optionally, the second frequency point may be a frequency point that is lower than the priority of the first frequency point and higher than the priorities of other frequency points in the multiple frequency points indicated by the measurement control information, that is, the second frequency point belongs to the second highest priority among the multiple frequency points.

And S107, under the condition that the timing time does not reach the preset duration and the signal quality value of the second cell corresponding to the second frequency point is greater than the preset threshold value, the UE sends a measurement report of the second cell to the network equipment and stops timing.

And S108, under the condition that the timing time does not reach the preset duration and the signal quality value of the second cell corresponding to the second frequency point is less than or equal to the preset threshold value, the UE measures the third frequency point according to the measurement control information.

Optionally, the third frequency point may be a frequency point, among the plurality of frequency points indicated by the measurement control information, which is lower than the priorities of the first frequency point and the second frequency point and higher than the priorities of the other frequency points.

For the descriptions of S107 and S108, reference may be made to the description of the signal quality of the first cell corresponding to the first frequency point in the foregoing embodiment, and details are not repeated here.

According to the voice fallback method provided by the embodiment of the application, before the timing duration of the UE reaches the preset duration, when the signal quality of the cell corresponding to the first frequency point does not meet the requirement, the UE can select a cell with the signal quality meeting the requirement from the cells corresponding to the multiple frequency points by measuring the second frequency point or the third frequency point, and report a measurement report of the cell to the network equipment. And then the UE can fall back to a cell with signal quality meeting the requirement.

Further, as shown in fig. 2, after S104, the speech fallback method provided in the embodiment of the present application may further include S109 described below.

And S109, when the timing time reaches a preset time length and the signal quality values of all the cells corresponding to all the measured frequency points are less than or equal to a preset threshold value, the UE stops timing and sends a measurement report of the target cell to the network equipment.

And the target cell is the cell with the highest signal quality value in all the cells corresponding to all the measured frequency points.

When the timing time reaches a preset time length, if the signal quality values of all cells corresponding to all frequency points (e.g., a first frequency point, a second frequency point and a third frequency point) measured by the UE are all less than or equal to a preset threshold value, that is, the signal quality values of all cells corresponding to all frequency points cannot meet the user requirement, the UE may select a cell with the highest signal quality value from all cells corresponding to all measured frequency points, to serve as a target cell, stop timing, and send a measurement report of the target cell to the network device. Therefore, the voice fallback of the UE can be guaranteed with the highest quality as far as possible under the condition that the signal quality values of all the cells corresponding to all the frequency points cannot meet the user requirements.

According to the voice fallback method provided by the embodiment of the application, after the timing duration of the UE reaches the preset duration, if the signal quality values of all the cells corresponding to all the frequency points cannot meet the user requirements, the UE selects one cell with the highest signal quality value from all the cells corresponding to all the measured frequency points, so that the requirement that a measurement report sent to network equipment is the measurement report of the cell with the highest signal quality value can be met, and the voice fallback of the UE is guaranteed.

It should be noted that, in the voice fallback method provided in the embodiment of the present application, the execution main body may be a voice fallback device, or a control module in the voice fallback device, configured to execute the voice fallback method. The embodiment of the present application takes the voice fallback method executed by the voice fallback apparatus as an example, and the voice fallback apparatus provided in the embodiment of the present application is described.
