Description

Determination method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining.

Background

In the prior art, after a terminal is deployed or moved to a non-coverage area of its home operator, it may search for other operator networks, and obtain network connection based on wireless channels of the other operator networks in a roaming manner. However, when the terminal is in a roaming network, the terminal may continuously perform home public mobile network (HPLMN) cell search (i.e., search for its home operator). If the roaming terminal is in a region where the home operator does not have network coverage, the terminal continuously performs home cell search, which greatly increases its power consumption but cannot return to the home operator. However, if the roaming terminal does not perform the home cell search for a long time, the roaming terminal may perform network connection based on the roaming network for a long time, and the roaming terminal may generate a high communication cost due to a high roaming cost.

The following describes a determination method provided by an embodiment of the present invention with reference to the determination device 100 shown in fig. 1.

As shown in fig. 2, the determining method provided in the embodiment of the present invention includes:

s201, determining that the equipment 100 acquires target data.

Wherein the target data includes: the terminal comprises an identification of a current service cell, an identification of a target cell, a target distance and a first number.

The cell identifier may be a cell Identity document (cellID) of the cell, or may be other types of identifiers. The embodiment of the present invention is not limited thereto. The following embodiment of the present invention takes the identifier of the cell as the cellID of the cell as an example for description.

The target cell is the serving cell where the terminal is located when the terminal performs the home search last time.

The cellID of the serving cell in which the terminal is currently located may be represented by CellIDs.

The cellID of the serving cell where the terminal was located when the terminal last performed the home search may be represented by cellID s'.

The target distance is the distance between the current position of the terminal and the position of the terminal when the terminal executes the home location search last time. The target distance may be denoted by d. The target distance can be calculated by the longitude and latitude between the two positions.

The first number is the number of search cycles for which the terminal has not performed the home cell search continuously before the current search cycle. The first number may be n _noserch And (4) showing. The terminal adds 1 to the first number in the case where the home cell search is not performed in the search period. The terminal sets the value of the first number to 0 in the case of performing the home search in the search period.

Optionally, the target data may further include: the remaining capacity of the terminal, the target data amount, the target value and the second quantity.

The remaining capacity of the terminal may also be referred to as a remaining capacity percentage of the terminal, and may be represented by l _battery And (4) showing.

Residual capacity l of terminal _battery Satisfies the formula: l _battery ＝C _remain /C _total ×100％。

C _remain Is the remaining capacity of the terminal. C _total Is the total charge of the terminal.

The target data volume is the data volume transmitted by the terminal through the application layer between the current time and the time when the terminal performs the home cell search last time. The target data amount may be denoted by b. The unit of the target data amount may be a byte (byte).

The target value is used for representing the condition of the service cell where the terminal is located currently. The target value may be represented by R. The R value is increased, which indicates that the load of the serving cell where the terminal is currently located is higher or the interference is larger, and the terminal should return to the home cell as much as possible.

The target value R satisfies the formula: r =10lg (RSSI-N × RSRP).

Reference Signal Receiving Power (RSRP) is defined as the linear average of the power contributions (in megawatts (mW)) of the resource elements carrying the cell-specific reference signal over the considered measurement band.

The Received Signal Strength Indication (RSSI) is the thermal noise contained within the bandwidth defined by the receiver pulse shaping filter and the noise generated by the receiver. RSSI is in units of mW.

N denotes the number of Resource Blocks (RBs) in the RSSI measurement bandwidth.

The second number is the number of target search cycles. The target search period is a search period in which the terminal performs a home search but the search fails. The second number may be n _fail And (4) showing. If the terminal fails to search for the home location, 1 is added to the value of the second number. If the terminal has successfully performed the attribution and the search, the value of the second number is set to 0.

S202, under the condition that at least one condition in the first type of conditions is met, the device 100 determines that the terminal executes the home cell search in the current search period.

Wherein the first type of condition comprises: the identification of the current service cell of the terminal is not equal to the identification of the target cell, the target distance is greater than or equal to a first threshold value, and the first number is greater than or equal to a second threshold value.

The first threshold may be denoted by D. The first threshold satisfies the formula: d = D _bs /2。

D _bs Terminal D deployed in urban environment for terminal deployment and average inter-station distance of application scene _bs The value is smaller than that of a terminal deployed in a remote environment, and if the terminal is likely to move in multiple scenes, several scenes D are taken _bs A minimum value.

The second threshold may be denoted by M2. The setting can be made according to a return policy, and the M2 value can be reduced if the terminal is expected to return to the home network as much as possible. For example, M2 may be 100. The second threshold is used for triggering the terminal in a roaming state for a long time to try to execute home cell search after roaming occurs to a fixed scene due to coverage holes and other problems, and avoiding the situation that the terminal cannot return to the home cell after the coverage of the home cell is improved due to the fact that the terminal roams for a long time due to unchanged position.

It should be noted that the cellID of the serving cell where the terminal is currently located is not equal to the cellID of the serving cell when the terminal performs the previous home cell search, which indicates that the serving cell where the terminal is currently located and the cell where the terminal performs the previous home cell are not the same cell.

In the case where the terminal does not have a Global Positioning System (GPS) function, the target distance is not satisfied by default to be greater than or equal to the first threshold.

It can be seen from S201-S202 that, in the embodiment of the present invention, the terminal performs the home cell search only in the current search period, instead of continuously performing the home cell search, when a certain condition is satisfied. Therefore, the method avoids the terminal from blindly executing the home cell search, and solves the problem of how to make the terminal reasonably execute the home cell search.

Referring to fig. 2, as shown in fig. 3, the determining method provided in the embodiment of the present invention may further include:

s203, the determining device 100 determines that the terminal does not perform home cell search in the current search cycle if all the conditions in the first type of conditions are not satisfied.

And S204, determining that the searching frequency of the next searching period is a first numerical value under the condition that the first condition is met by the device 100.

Wherein the first value may be represented by Ts. The first value may be 100 in seconds. I.e. the search frequency is 100 seconds. The search period in which the search frequency is the first value may be referred to as a short period.

The first condition is that the remaining capacity of the terminal is greater than or equal to a third threshold and at least one condition of a second type of condition is satisfied.

The third threshold may be represented by L, and the third threshold L satisfies the formula: l = 1-L'/(k 1 × k 2).

And k1 is the service life grade of the terminal. Related to the terminal service life class. For example, it may be as shown in table 1.

TABLE 1

Predicted service life of terminal	K1
		Less than one year	1
1-3 years old	1.1
		More than 3 years	1.3

K2 is the battery replacement difficulty level. Related to the difficulty of replacing the terminal battery. For example, as shown in Table 2.

L' is an absolute threshold of the power used by the terminal, and may be 0.7, for example.

TABLE 2

Ease of battery replacement	K2
		Easy to use	1
Difficulty in	1.1

When the terminal supplies power to the power supply, the third threshold may be 0, that is, the terminal supplied with power by the default power supply always satisfies the condition that the remaining power of the terminal is greater than or equal to the third threshold.

The second type of condition includes: the target data amount is greater than or equal to the fourth threshold, and the target value is greater than or equal to the fifth threshold.

The fourth threshold may be denoted by B. The fourth threshold may also be referred to as a data volume threshold. The fourth threshold value can be calculated according to roaming charges and the sensitivity of different internet of things terminal users to charges, wherein the higher the roaming charges are, the smaller the B value is, and the higher the sensitivity of the users to charges is, the smaller the B value is. The unit of the fourth threshold is byte.

For the case that the target data volume is greater than or equal to the fourth threshold, the traffic volume is considered to be large, and the corresponding roaming and non-roaming tariff difference is not within the acceptable range, so that the target data volume is urgently returned to the home cell. Correspondingly, for the case that the target data volume is smaller than the fourth threshold, the traffic volume is considered to be small, and the corresponding roaming and non-roaming tariff difference is within the acceptance range, so that the return to the home cell is not urgent.

The fifth threshold may be estimated or tested. For example, an average estimated value or an average test value of a target value (R value) at 70% of the terminal serving cell load may be taken.

It is worth mentioning that the search frequency of the first search period may be a fixed value. For example, the search frequency of the first search period may be fixed to a first value, i.e., the first search period is fixed to a short period.

S205, determining that the device 100 determines the search frequency of the next search cycle to be the second value when the first condition is not satisfied and at least one condition of the third type of condition is satisfied.

Wherein the second value may be denoted by Tl. The second value may be 10000 in seconds. I.e. the search frequency is 10000 seconds. The search period in which the search frequency is the second value may be referred to as a long period.

The third type of condition includes: the second quantity is greater than or equal to a sixth threshold, the first quantity is greater than or equal to a seventh threshold, and the residual capacity of the terminal is greater than or equal to a third threshold.

The sixth threshold may be represented by N1. The sixth threshold may also be referred to as a return failure threshold. The value of N1 may be increased if the terminal is expected to return to the home network as much as possible. For example, N1 may be 5.

The seventh threshold may be denoted by M1. The value of M1 may be increased if the terminal is expected to return to the home network as much as possible. M1 is less than M2. For example, M1 may be 5.

And S206, under the condition that the first condition is not met and all the conditions in the third type of conditions are not met, the determining device 100 determines that the searching frequency of the next searching period is the same as the searching frequency of the current searching period.

Illustratively, the frequency of the current search period of the terminal is a first value. The determination apparatus 100 determines the search frequency of the next search cycle to be the first value in the case where the first condition is not satisfied and all of the third type conditions are not satisfied.

For another example, the frequency of the current search period of the terminal is a second value. The determination device 100 determines the search frequency of the next search cycle to be the second numerical value if the first condition is not satisfied and all of the third type conditions are not satisfied.
