The RSRP is a reference signal received power (reference signal receiving power, RSRP) value measured by the terminal to be upgraded.

The KRSRP is the difference between the RSRP value measured by the terminal to be upgraded and the RSRP threshold. The KRSRP may be calculated according to a relation "krsrp=rsrp-RSRP 0", where RSRP is an RSRP value measured by the terminal to be upgraded, and RSRP0 is an RSRP threshold. In practical application, in a long term evolution (long term evolution, LTE) system, RSRP0 is mainly-95 dBm. In a new radio, NR, system, RSRP0 is predominantly-105 dBm.

KSINR is the difference between the signal-to-interference-plus-noise ratio (signal to interference plus noise ratio, SINR) value measured by the terminal to be upgraded and the SINR threshold, and KSINR can be calculated according to the relation "ksinr=sinr-SINR 0", where SINR is the SINR value measured by the terminal to be upgraded and SINR0 is the SINR threshold. In practical application, in the LTE system, SINR0 is mainly 5dB. In the NR system, SINR0 is mainly 0dB. Ks is the neighbor terminal parameter of the terminal to be upgraded.

Ks can be calculated according to a relation 'Ks=X-X0', wherein X in the relation is the number of neighbor terminals of the terminal to be upgraded, X0 can be an average value of the number of neighbor terminals of all the terminals to be upgraded, and X0 can also be an average value of the number of neighbor terminals of the terminal.

Kstatus is the state of the terminal to be upgraded. The state of the terminal to be upgraded may include a connected state and an idle state. The terminal firmware upgrade apparatus 300 may determine a value of Kstatus of the terminal to be upgraded in the connected state as 1 and a value of Kstatus of the terminal to be upgraded in the idle state as 0. The embodiment of the invention introduces Kstatus for the preferential upgrading of the terminal to be upgraded in a connected state. Because the terminal in the connection state can carry out firmware upgrade along with the service, no additional network connection is required to be established, and network resources can be saved.

The terminal firmware upgrading device 300 determines a first priority of each of the plurality of terminals to be upgraded according to KRSRP, KSINR, ks and Kstatus of each of the plurality of terminals to be upgraded.

Wherein the first priority may be represented by a P value or a priority P value. The larger the value of the first priority of the terminal to be upgraded, the higher the first priority of the terminal to be upgraded.

In practical applications, the terminal firmware upgrading apparatus 300 may determine the first priority of the terminal to be upgraded according to KRSRP, KSINR, ks and the relation table of Kstatus and the first priority shown in table 1.

TABLE 1

The terminal firmware upgrading device 300 determines the second priority of each of the plurality of terminals to be upgraded according to RSRPavr1, RSRPavr2, RSRPavr3 and RSRP of each of the plurality of terminals to be upgraded.

Wherein, RSRPavr1 is the average value of RSRP of the first terminal to be upgraded, RSRPavr2 is the average value of RSRP of the second terminal to be upgraded, and RSRPavr3 is the average value of RSRP of the third terminal to be upgraded. The second priority may be represented by a K value or a priority K value. The larger the value of the second priority of the terminal to be upgraded, the higher the second priority of the terminal to be upgraded.

Specifically, the second priority of the first terminal to be upgraded may be calculated according to the relation "k= |rsrp-RSR Pavr 1|".

The second priority of the second terminal to be upgraded can be calculated according to the relation "k= |rsrp-RSRPavr 2|".

The second priority of the third terminal to be upgraded can be calculated according to the relation "k= |rsrp-RSRPavr 3|".

The terminal firmware upgrading device 300 determines the comprehensive priority of each of the plurality of terminals to be upgraded according to the first priority of each of the plurality of terminals to be upgraded and the second priority of each of the plurality of terminals to be upgraded.

The comprehensive priority of the terminal to be upgraded represents the firmware upgrading priority of the terminal to be upgraded, and the larger the numerical value of the comprehensive priority of the terminal to be upgraded is, the higher the comprehensive priority of the terminal to be upgraded is.

The integrated priority may be derived from a simple combination of the first priority and the second priority. For example, the first priority is 10 and the second priority is 0.1, and the terminal firmware upgrade apparatus 300 determines that the comprehensive priority of the terminal to be upgraded is <10,0.1> according to the first priority and the second priority. The composite priority may also be derived from a combination of the first priority and the second priority, and an algorithm (e.g., a weighted sum algorithm). The embodiment of the present invention is not limited thereto.

S302, the terminal firmware upgrading device 300 determines the coverage grade of the area where each terminal to be upgraded is located in the plurality of terminals to be upgraded.

The coverage levels may include a first coverage level, a second coverage level, and a third coverage level.

Specifically, the terminal firmware upgrade apparatus 300 determines the coverage level of the area where each of the plurality of terminals to be upgraded is located according to RSRPavr, RSRPd' and RSRP of each of the plurality of terminals to be upgraded.

Wherein RSRPavr is an average value of RSRP of a plurality of terminals to be upgraded, and when the number of terminals to be upgraded is n, RSRPavr may be represented as "rsrpavr= (rsrp1+rspp2+rsrp3+ … … +rsrpn)/n". And RSRPn is the RSRP of the nth terminal to be upgraded, and the rest is the same.

RSRPd' is the standard deviation of the RSRP of the plurality of terminals to be upgraded. When the number of terminals to be upgraded is n, RSRPd' may be expressed as

Is the root number.

Optionally, for each terminal to be upgraded in the plurality of terminals to be upgraded, if RSRP of the terminal to be upgraded is greater than rsrpavr+rsrpd', the terminal firmware upgrading device 300 determines that the coverage level of the area where the terminal to be upgraded is located is the first coverage level.

And if the RSRP of the terminal to be upgraded is smaller than the RSRPavr-RSRPd', determining that the coverage grade of the area where the terminal to be upgraded is positioned is a third coverage grade.

If the RSRP of the terminal is not more than RSRPavr+RSRPd 'and not less than RSRPavr-RSRPd', determining that the coverage level of the area where the terminal to be upgraded is located is a second coverage level.

S303, the terminal firmware upgrading device 300 determines the target terminal.

The target terminals comprise a first target terminal, a second target terminal and a third target terminal.

The first target terminal is a terminal to be upgraded, the comprehensive priority of which is arranged in the first L1 bit, in the first terminal to be upgraded. The first terminal to be upgraded is a terminal to be upgraded, wherein the area of the terminal to be upgraded is a first coverage level. L1 is a positive integer.

The second target terminal is a terminal to be upgraded, the comprehensive priority of which is arranged in the front L2 position, in the second terminal to be upgraded. The second terminal to be upgraded is a terminal to be upgraded, of which the area is a second coverage level, in the plurality of terminals to be upgraded. L2 is a positive integer.

The third target terminal is a terminal to be upgraded, the comprehensive priority of which is arranged in the first L3 bits, in the third terminal to be upgraded. The third terminal to be upgraded is a terminal to be upgraded, the area of which is a third coverage level, among the plurality of terminals to be upgraded. L3 is a positive integer.

Alternatively, L1 may be according to the relation

And (5) calculating to obtain the product. L is the number of target terminals.

TBS1 is the transport block size corresponding to the first condition. The first condition is sinr=sinravr 1 and the allocated resource is nresource. SINRavr1 is an average value of SINR of the first terminal to be upgraded. nresource is the total number of resources in time units.

TBS2 is the corresponding transport block size under the second condition. The second condition is sinr=sinravr 2 and the allocated resource is nresource. SINRavr2 is an average value of SINR of the second terminal to be upgraded.

The values of TBS1 and TBS2 can be queried through SINR and TBS mapping list (the mapping list is obtained from historical data of network management side, the network management side adopts different scheduling algorithms, and the obtained mapping list is different).

n1 is the number of first terminals to be upgraded. n2 is the number of second terminals to be upgraded. And n3 is the number of the third terminals to be upgraded.

Is rounded downwards.

Alternatively, L2 may be calculated according to the relationship "l2=l-L1-L3".

Alternatively, L3 may be according to the relation

And (5) calculating to obtain the product.

Alternatively, L may be calculated according to the relation "l=nresource (1-Rresource) ×rservice channel α/Nresource".

Nresource is the total number of resources in a time unit, in an LTE system, nresource is the total number of physical resource blocks (physical resource block, PRB) in a time unit, in an NB system, nresource is the total number of subcarriers in a time unit, and Nresource can be calculated according to the system bandwidth.

Rresource is the average resource utilization rate of a cell, rresource is the average utilization rate of PRB of the cell in an LTE system, and Rresource is the average utilization rate of sub-carriers of the cell in an NB system.

The Rservicechannel is a traffic channel resource occupation ratio and can be calculated according to the relation "rservicechannel=ns/nocccupy". Ns is the average occupied resource number of the service channel, ns in the LTE system is the average occupied PRB number of the service information, ns in the NB system is the average occupied subcarrier number of the service information, and Ns can be obtained from the network management system. Nocccupy is the average number of occupied resources of a cell.

Alpha is a correction coefficient and is related to the resource occupancy rate of the terminal upgrade time period. The resource occupancy rate is higher than the average resource occupancy rate when the service is busy, the time period of terminal upgrading is the time period when the service is busy, so that network congestion is avoided for avoiding terminal upgrading, and the alpha value can be smaller than 1. The resource occupancy rate in idle service is lower than the average resource occupancy rate, and the alpha value can be larger than 1. For example, the time period for upgrading the terminal is 0.7 for the busy hour α, and the time period for upgrading the terminal is 1.2 for the idle hour α. The period of time for terminal upgrade may be 0.9 for other periods of time (neither when the service is busy nor when the service is idle) a.

nresource is the number of resources scheduled to be allocated to each terminal for upgrade. The value of nresource is related to the size of the firmware package and the time when the upgrade is expected to be completed, and the larger the firmware package, the shorter the expected completion time, and the larger the value. Nresource defaults to 1prb in LTE system and one subcarrier in nb system.

In practical application, the terminal firmware upgrading device 300 obtains a plurality of terminal firmware upgrading lists according to the comprehensive priority of the terminal to be upgraded and the coverage level of the area where the terminal to be upgraded is located, and then determines the target terminal from the terminal firmware upgrading list of each coverage level area respectively. For example, the coverage levels include a first coverage level, a second coverage level, and a third coverage level. The terminal firmware upgrade apparatus 300 obtains a terminal firmware upgrade list of the first coverage level area, a terminal firmware upgrade list of the second coverage level area, and a terminal firmware upgrade list of the third coverage level area.

As shown in table 2, the terminal firmware upgrade list may include: the serial number of the terminal (ordering of the integrated priority of the terminal), the terminal name, the terminal identification, the firmware version of the terminal, the P value of the terminal (first priority), the K value of the terminal (second priority), and the integrated priority of the terminal. The terminal identity includes, but is not limited to, an international mobile equipment identity (IMEI, international mobile equipmentidentity), and embodiments of the present invention are merely exemplified with the terminal identity being the IMEI.

TABLE 2

S304, the terminal firmware upgrading device 300 determines that the target terminal obtains an upgrading packet through the cellular network.

The upgrade package is used for upgrading the firmware in the target terminal.

Specifically, the terminal firmware upgrade apparatus 300 sends a first message to the target terminal, where the first message is used to instruct the target terminal to download the upgrade package through the cellular network connection server.

In practical application, after the target terminal finishes upgrading, the terminal firmware upgrading device 300 determines a new target terminal according to the comprehensive priority of the terminal to be upgraded. When the target terminal firmware upgrade fails, the terminal firmware upgrade apparatus 300 will minimize the comprehensive priority of the target terminal, and determine a new target terminal according to the comprehensive priority of the terminal to be upgraded. The failure of upgrading the terminal firmware means that the repeated upgrading times of the terminal reach a preset threshold.

S305, the terminal firmware upgrading device 300 determines that the first neighbor terminal obtains an upgrading packet through a near field communication technology after the target terminal firmware is upgraded.

The upgrade package is used for upgrading firmware in the first neighbor terminal, the first neighbor terminal and the target terminal are the same in model number, and signal strength between the first neighbor terminal and the target terminal is larger than a threshold value. And when the signal strength between the two terminals is greater than the threshold value, the two terminals can be connected normally and exchange data. When the two are communicated through Bluetooth, the threshold value is mainly-80 dBm.

Specifically, the terminal firmware upgrade apparatus 300 sends a second message to the first neighboring terminal, where the second message is used to instruct the first neighboring terminal to connect to the target terminal through the near field communication technology to download the upgrade package.

In practical application, after the target terminal firmware is upgraded, an upgrade success message is sent to the terminal firmware upgrading device 300. After receiving the upgrade success message, the terminal firmware upgrade apparatus 300 determines the neighbor terminal of the target terminal according to the terminal relationship list. And then, sequentially informing the neighbor terminals of the target terminal to connect the target terminal through the Bluetooth network for upgrading. The order of notification may be to notify from high to low bluetooth signal strength between the neighbor terminal and the target terminal. If the notified neighbor terminal firmware upgrade fails, the terminal firmware upgrade apparatus 300 re-notifies the neighbor terminal to upgrade after other neighbor terminals complete the upgrade. As shown in table 3, the terminal relation list may include a terminal name of each terminal, a terminal identifier, a firmware version of the terminal, the number of neighbor terminals, and a name of each neighbor terminal, where the terminal name is unique and corresponds to the terminal identifier one by one. The terminal may periodically measure the neighbor terminals and periodically update the number of neighbor terminals and neighbor terminal information to the terminal firmware upgrade apparatus 300.

As can be seen from the above steps (S301-S305), only the target terminal is upgraded by the cellular network, and the rest of terminals to be upgraded are all upgraded by the near field communication technology. In the prior art, most of terminals are upgraded by cellular networks. Therefore, compared with the prior art, the embodiment of the invention reduces the cellular network utilization rate in the process of upgrading the terminal firmware and reduces the network load rate in the process of upgrading the terminal firmware. Therefore, the problem of network overload caused by terminal firmware upgrading is solved. In addition, the embodiment of the invention determines the target terminals from the terminals to be upgraded in the areas with different coverage levels respectively by introducing the coverage levels, and then uses the target terminals as seed nodes to help the neighbor terminals to finish remote firmware upgrading based on the near-field communication technology, thereby reducing the total time for finishing remote firmware upgrading for all the terminals to be upgraded and improving the remote firmware upgrading efficiency.
