Description

Method and device for reporting measurement report and obtaining speed status by mobile terminal

The present invention relates to the field of communications, and in particular, to a method and apparatus for reporting a measurement report by a mobile terminal and obtaining a state of speed.

Background technique

In the wireless network, in order to ensure the continuity of the service of the mobile terminal in the case of mobile, it is necessary to switch the cell where the mobile terminal is located to the access network control node or the core network node serving the mobile terminal, in LTE (Long Term Evo lut ion, In the long-term evolution, the access network control node is an ENB (evolved NodeB), and the core network node is an MME (Mob i i ty Management Entity, mobile management entity); in UMTS (Univer sa lbibi le Te In the lecommunica network, the access network control node is the RNC (Radio Resource Control), and the core network node is the MSC (Mobi le Services Swi tching Center) or the SGSN. (Serving GPRS Suppor t Node, packet service processing node).

The process of switching the cell in which the mobile terminal is located to the access network control node or the core network node serving the mobile terminal is initiated by the ENB, and is a target cell that determines whether to switch and handover according to the measurement report reported by the mobile terminal. In order not to affect the judgment of the ENB, the measurement report reported by the mobile terminal is very important. For a high-speed or medium-speed mobile terminal, it is more important to report the real-time performance of the measurement report. Otherwise, the mobile terminal has crossed the cell edge, and the measurement report has not been reported, resulting in the mobile terminal not being able to switch to other cells in time, so that the mobile terminal The call was interrupted. There are currently two factors affecting the measurement report, one is the hysteresis threshold and the other is TTT (tr igger to t imer). In order to realize real-time reporting of measurement reports by high-speed mobile terminals and medium-speed mobile terminals, TTT is set to a small value in order to set high-speed and medium-speed mobile terminals with the lag time required for high-speed mobile terminals when TTT is set. After reaching the hysteresis threshold of the reported measurement report, the measurement report can be reported to the corresponding ENB in a short period of time, to a certain extent, high speed and medium speed. The mobile terminal reports the measurement report in time; however, because the set lag time is relatively short, for a mobile terminal at a low speed or a normal speed, a TTT of a smaller value causes the mobile terminal to report the measurement report multiple times, and the ENB cannot be reported according to the report. As a result, the cell handover is performed reasonably.

For the shortcomings of setting a fixed TTT with the above, the real-time reporting report of the mobile terminal of different speeds cannot be solved, and a method for reporting the measurement report by distinguishing the speed of the mobile terminal is used, and the method is mainly used for the movement in the connected state. Terminal (the status of the mobile terminal is two, one is idle and the other is connected). The specific implementation manner of the method for distinguishing the speed of the mobile terminal by reporting the measurement report is as follows: setting an initial hysteresis threshold and TTT according to the condition of the low-speed mobile terminal performing cell handover, and adjusting the TTT according to the speed of the mobile terminal moving, such as When the mobile terminal is changed from a low-speed user to a high-speed user, the measurement report is sent to the ENB within a short lag time by shortening the TTT, so that the ENB performs timely on the mobile terminal according to the reported measurement report. Switching of the serving cell.

In the process of reporting the different speed state measurement reports, the inventor found that when the mobile terminal moves very fast, even if the TTT is adjusted to 0, the measurement result cannot be reported to the ENB in time, so that the ENB cannot be timely. The handover of the serving cell causes the mobile terminal to drop out or fail to switch within a certain time range.

In order to speed according to the idle state Adjusting the lag time or/and the hysteresis threshold to cause the mobile terminal to report the measurement report for the first time after reporting the connection state according to the adjusted hysteresis threshold or/and the lag time, after the first report measurement report ends, The acquisition of the speed of the mobile terminal is obtained according to the moving speed when the mobile terminal is connected.

After the foregoing technical solution provided by the embodiment of the present invention, the mobile terminal adjusts the lag time to a hysteresis threshold corresponding to the current speed state of the mobile terminal according to the obtained current speed state of the mobile terminal, or/and adjusts the lag time.

In the prior art, when the mobile terminal is at the cell edge, when the mobile terminal performs the idle state switching to the high-speed mobile connection state, the reporting report of the idle state cell reselection has not been initiated, and the mobile terminal has moved to another cell. After moving to another cell, the measurement report is reported according to the speed state of the mobile terminal in the connection state, so that the mobile terminal cannot report the measurement report in time, and the measurement report report when the mobile terminal state is switched is missed, so that the mobile The terminal's online service is suspended.

Example 2 The embodiment of the invention provides a method for reporting a measurement report by a mobile terminal. The method can adjust the delay threshold to enable the mobile terminal in various speed states to timely and accurately report the measurement report, as shown in FIG. include:

901. Set an initial delay threshold for reporting, by the mobile terminal, the measurement report. The hysteresis threshold can be set according to an empirical value. The embodiment of the present invention sets the hysteresis threshold in a medium speed state as an example.

902. Obtain a current speed state of the mobile terminal. When the current speed state of the mobile terminal is a medium speed, perform step 903. When the current speed state of the mobile terminal is high speed, perform step 904; when the current speed of the mobile terminal is When the state is low speed, step 905 is performed.

903. When the mobile terminal determines that the speed state of the mobile terminal is the medium speed state, since the initial hysteresis threshold is set according to the medium speed state of the mobile terminal, it is not necessary to adjust the initially set hysteresis threshold, so that the The mobile terminal in the medium speed state reports the measurement report in real time, and step 906 is performed.

904. When the mobile terminal determines that the speed state of the mobile terminal is a high speed state, the initial hysteresis threshold is set according to the medium speed state of the mobile terminal, and the hysteresis threshold of the mobile terminal is adjusted to a hysteresis threshold corresponding to the high speed. The initial delay threshold is adjusted to be small, so that the mobile terminal in the high speed state can report the measurement report in real time to step 906.

There are two methods for reducing the hysteresis threshold described above, as follows: First, selecting a hysteresis threshold corresponding to the high-speed state from a preset hysteresis threshold; second, multiplying the initially set hysteresis threshold by less than 1 And the scaling factor corresponding to the high speed state described above obtains a hysteresis threshold corresponding to the high speed state described above.

905. When the mobile terminal determines that the speed state of the mobile terminal is in a low speed state, the initial hysteresis threshold is set according to a medium speed state of the mobile terminal, and the hysteresis time of the mobile terminal is adjusted to a hysteresis corresponding to the low speed state. The threshold, that is, the initial hysteresis threshold is increased, so that the mobile terminal in the low-speed state can report the measurement report in real time.

There are two methods for increasing the hysteresis threshold, as follows: First, selecting a hysteresis threshold corresponding to the low speed state from a preset hysteresis threshold; second, initially setting The hysteresis threshold is multiplied by a scaling factor greater than 1 and corresponding to the low speed state described above, and a hysteresis threshold corresponding to the low speed state described above is obtained.

906. The mobile terminal reports the measurement report according to the adjusted hysteresis threshold.

The embodiment of the present invention further provides an apparatus for reporting a measurement report. As shown in FIG. 10, the apparatus includes: 1001, an obtaining unit 1002, an adjusting unit 1003, and a reporting unit 1004.

The device sets the initial hysteresis threshold and the hysteresis time of the measurement report reported by the mobile terminal through the setting unit 1001. In this embodiment, the hysteresis threshold and the hysteresis time are set in the medium speed state as an example.

The obtaining unit 1002 obtains the speed state of the mobile terminal. After obtaining the current speed state of the mobile terminal, the adjusting unit 1003 adjusts the hysteresis threshold of the reported measurement report to the hysteresis threshold corresponding to the speed state. There are two methods for adjusting the hysteresis threshold, specifically: first, selecting a hysteresis threshold corresponding to the speed state from a preset hysteresis threshold; second, multiplying the initially set hysteresis threshold by the speed state The corresponding scaling factor is used to obtain a hysteresis threshold corresponding to the speed state. After the hysteresis threshold is adjusted to a hysteresis threshold corresponding to the current state of the mobile terminal, the reporting unit 1 004 reports the measurement report according to the adjusted hysteresis threshold.

In the embodiment of the present invention, when the initial hysteresis threshold and the lag time are set according to the low speed state of the mobile terminal, when the current speed state of the mobile terminal is high speed or medium speed, the delay threshold of the mobile terminal is adjusted to be smaller, that is, The initial hysteresis threshold is multiplied by a scaling factor of less than 1 corresponding to the high-speed state, so that the mobile terminal in the high-speed or medium-speed state reaches the standard of reporting the measurement report as soon as possible, so that the mobile terminal in the high-speed state can report in time. measurement report.

In the embodiment of the present invention, when the initial hysteresis threshold and the lag time are set according to the high-speed state of the mobile terminal, when the current speed state of the mobile terminal is medium speed or low speed, the delay threshold of the mobile terminal is adjusted to be longer. The initial hysteresis threshold is multiplied by a scaling factor greater than one corresponding to the high speed state, so that the mobile terminal in the medium or low speed state can report the measurement report in time.

In the embodiment of the present invention, the hysteresis threshold is adjusted to be based on the speed state of the mobile terminal. The hysteresis threshold is adjusted to be smaller, so that the mobile terminal in the high-speed state can reach the standard for reporting the measurement report in time, so that the mobile terminal can count down the hysteresis time in advance, so that a terminal in a high-speed state can report the measurement report in time; When the mobile terminal is at a low speed, because the mobile terminal in the low speed state moves relatively slowly, the hysteresis threshold is adjusted to be larger, so that the mobile terminal starts the countdown of the lag time later, and the low speed mobile terminal can still report the measurement report in time. .

Example 3

An embodiment of the present invention provides a method for reporting a measurement report by a mobile terminal, where the mobile terminal in various speed states can implement a measurement report in time and accurately by adjusting a lag time, as shown in FIG. 11 , where the method includes :

1101. Set the initial hysteresis time of the >3⁄4 measurement on the mobile terminal. The mobile terminal has two states, an idle state when not online, and a connection state when online. The solution in this embodiment is to adjust the lag time so that the mobile terminals in different speed states can report the measurement report in real time, so the above lag is caused. The setting of the time is set according to the high-speed state, so that the mobile terminal at high speed can report the measurement report in time.

The first speed state of the mobile terminal is obtained; when the current speed state of the mobile terminal is medium speed or low speed, step 1103 is performed; when the current speed state of the mobile terminal is high speed, step 1104 is performed;

1103. The initial hysteresis time is adjusted according to a high-speed state of the mobile terminal, and the initial set hysteresis time is adjusted to a hysteresis time corresponding to the above-mentioned medium-speed or low-speed state, that is, the initial hysteresis time is lengthened, so as to be in the middle The mobile terminal in the fast or low speed state can report the measurement report in time, and step 1105 is performed.

There are two methods for lengthening the hysteresis time, as follows: First, multiplying a preset hysteresis time by a scaling factor greater than 1 and corresponding to the medium or low speed state, The lag time corresponding to the medium or low speed state. The initial lag time is set according to the high-speed state of the mobile terminal, so that it is not necessary to change the lag time, so that the mobile terminal at high speed can timely and accurately report the measurement report.

11 05. The mobile terminal reports the measurement report according to the adjusted lag time.

The embodiment of the present invention further provides an apparatus for reporting a measurement report. As shown in FIG. 12, the apparatus includes: a setting unit 121, an obtaining unit 122, an adjusting unit 123, and a reporting unit 124.

The device sets the initial lag time for the mobile terminal to report the measurement report through the setting unit 121. In the present embodiment, the initial hysteresis time is set as an example in a high speed state.

The device obtains the speed state of the mobile terminal by the obtaining unit 122. After the current speed state of the mobile terminal is acquired, the delay time of reporting the measurement report is adjusted by the adjusting unit 123 to a hysteresis time corresponding to the speed state. There are two methods for adjusting the hysteresis time, specifically: multiplying the initially set hysteresis time by a scaling factor corresponding to the speed state to obtain a hysteresis time corresponding to the speed state. After the hysteresis time is adjusted to the hysteresis time corresponding to the current state of the mobile terminal, the reporting unit 124 reports the measurement report according to the adjusted hysteresis time.

In the embodiment of the present invention, according to the speed state of the mobile terminal, the hysteresis time is adjusted to be smaller than the hysteresis threshold setting, and the hysteresis time is set to be the shortest, so that the mobile terminal in the high speed state can be as soon as possible. At the same time as reporting the measurement report standard, the measurement report is reported in a short period of time, so that the high-speed mobile terminal can report the measurement report in time and accurately; when the mobile terminal is at low or medium speed, under the premise that the hysteresis threshold is small The delay time is adjusted to be longer, so that the mobile terminal at the low or medium speed waits for a longer lag time, and then reports the measurement report; because the moving speed of the low speed or medium speed mobile terminal is relatively slow, even if the lag time is faster than the high speed The lag time is longer, and the mobile terminal in the low speed or medium speed state can still report the measurement report in real time. In the high-speed mobile terminal, the set hysteresis time is relatively short, and the number of cell handovers is compared. More, the occupied air interface resources are more; but when the mobile terminal is in the low speed or medium speed state, the delay time is lengthened, the number of cell handovers is relatively small, and the occupied air interface resources are relatively small; Compared with the air interface resources reserved in the high speed state, the speed state saves air interface resources to a certain extent.

The adjustment hysteresis threshold in Embodiment 2 and the adjustment hysteresis time in Embodiment 3 can be used in combination to enable the mobile terminals in various speed states to report the measurement report in time. When the mobile terminal is in the high speed or medium speed state, the hysteresis time is adjusted to be relatively short, and the hysteresis threshold is adjusted to be smaller, so that the mobile terminal at high speed reaches the standard for reporting the measurement report earlier. After the standard is reached, the measurement report is reported in a shorter waiting time; when the mobile terminal is in the low speed state, the hysteresis time is adjusted to be relatively longer, and the hysteresis threshold is adjusted to be larger, so that the mobile terminal is moving at a lower speed. The mobile terminal has a relatively slow arrival report report corresponding to the speed state; thus, the mobile terminal in various speed states can report the measurement report in time.

According to the different speed states of the mobile terminal, the hysteresis time and the hysteresis threshold of the reported measurement report are adjusted, so that the number of times the mobile terminal in different speed states reports the measurement report is different. When the mobile terminal is in a high-speed state, the number of times the measurement report is reported in a certain period of time is relatively large, and the number of times of cell handover is also relatively large, so that the mobile terminal that moves at a high speed occupies more air resources; and the movement of the low-speed or medium-speed mobile The number of times that the terminal reports the measurement report within a certain period of time is relatively small, and the number of air interface resources occupied by the mobile terminal in the high-speed state is relatively small, compared with the state of the art in which various speed states reserve air interface resources at a high speed. The degree of air resources is saved.

Example 4

The embodiment of the invention provides a method for reporting a measurement report by a mobile terminal. The method can adjust the sampling period of the physical layer, so that the mobile terminal in various speed states can timely report the measurement report, as shown in FIG. As shown, the method includes:

1 301. Set the sampling period of the physical layer, such as setting the sampling period of the physical layer according to the low speed state.

1 302. In order to enable the mobile terminal in various speed states to report the measurement report in time, it is necessary to adjust the sampling period of the physical layer according to the current speed state of the mobile terminal, and adjust the physical state. Before the sampling cycle of the layer, it is first necessary to obtain the speed state of the mobile terminal.

1 303. Adjust a sampling period of the physical layer to a sampling period corresponding to the speed state. When the mobile terminal is in the high speed or medium state, the sampling period needs to be shortened, and the scale factor corresponding to the speed state is less than 1; when the mobile terminal changes from the high speed or medium speed state to the low speed state, The current sampling period is restored to the initially set sampling period, that is, the sampling period is lengthened, and the scale factor corresponding to the speed state is greater than 1. The scaling period scaling factor corresponding to the speed state is delivered by the radio resource control layer.

1304. Multiply the received scale factor by the initially set sampling period to obtain a sampling period corresponding to the speed.

1 305. After adjusting the sampling period to a sampling period corresponding to the current speed state of the mobile terminal, the physical layer reports the measurement report to the RRC layer according to the initial reporting upper layer measurement period.

An embodiment of the present invention provides an apparatus for acquiring a speed state of a mobile terminal. As shown in FIG. 16, the apparatus includes: a receiving unit 161, an obtaining unit 162, a comparing unit 163, and a determining unit 164.

The device receives the rate sent by the network side by the receiving unit 161, and the rate may be an empirical value; the obtaining unit 162 is configured to acquire the current moving speed of the mobile terminal; when the current moving speed of the mobile terminal is obtained, The mobile terminal compares the received rate with the current speed of the acquired mobile terminal by using the comparing unit 163 according to the current moving speed of the mobile terminal and the rate sent by the network side, when the mobile terminal is currently moving. When the speed is lower than the moving rate, the determining unit 164 is configured to determine a speed state of the mobile terminal as a low speed state; when the current moving speed of the mobile terminal is higher than the moving rate, and the mobile terminal is related to the rate When the difference is within the range of the difference between the preset medium speed state and the rate, the determining unit 164 is further configured to determine the speed state of the mobile terminal as the medium speed state; if the mobile terminal is currently moving at a high speed At the moving rate, and the difference between the mobile terminal and the rate is in the preset The difference is within the range of the speed state rate, the determination unit 164 for further speed state of the mobile terminal determines that the high speed.

When the current speed of the mobile terminal is obtained, the detecting module 1621 is configured to detect the moving speed of the mobile terminal by the physical layer of the mobile terminal; when detecting the current moving speed of the mobile terminal, the upper module 1622 is used for the physical layer of the mobile terminal. The detected speed is on the mobile terminal radio resource control layer.

In the prior art, there are two types of determining the speed state of the mobile terminal: First, when the mobile terminal is in an idle state, determining the speed state of the mobile terminal according to the number of times the mobile terminal reselects the cell within a certain time range; When the mobile terminal is in the connected state, the speed state of the mobile terminal is determined according to the number of times the mobile terminal performs cell handover within a certain time range. The determination of the speed of the above two mobile terminals is not real-time. When the mobile terminal suddenly changes the speed state in the long-term, the mobile terminal cannot obtain the speed state in time, resulting in an inaccurate reporting report. In the embodiment of the present invention, the current speed of the mobile terminal is obtained, and the received speed range sent by the access network control node is received. The determination of the speed state of the mobile terminal enables the state of the current speed acquired by the mobile terminal to be real-time, thereby ensuring the accuracy of reporting the measurement report.
