In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
With the development of the internet of things technology, the market puts higher requirements on a Subscriber Identity Module (SIM) card of the internet of things device, including: it is required to have higher physical properties, longer service life and higher reliability, more reliable and more wear-resistant physical connection contacts, and meet the requirements of some scenarios supporting remote configuration, remote activation, flexible user identity change over the air interface, and the like. Driven by the above demands, the global system for mobile communications association (GSMA) has proposed a technical system of e-SIM card to guide the SIM card to be developed into electronic card to meet the market demand.
Referring to fig. 1, a remote configuration architecture of an existing e-SIM card is provided, which includes a code number management system, an e-SIM card service acceptance and download trigger server (trigger server for short), an e-SIM card management platform, and a communication module of the e-SIM card, where the code number management system is a subsystem in an operator service system and is mainly responsible for allocating code numbers to the e-SIM card and managing the e-SIM card, the trigger server may trigger an internet of things device to complete downloading, activating, querying, or deleting a profile of the e-SIM card based on the e-SIM card management platform when communicating with the internet of things device, the e-SIM card management platform includes two parts, namely an e-SIM card data generation server and an e-SIM card download server, and is responsible for generating, storing and managing the profile data and executing the profile download, etc., L PA is a software package in the communication module of the e-SIM card, and includes local profile download (L PD) and local user interface (SIM card), and additionally, the manufacturer of the e-SIM card represents a manufacturer UI L.
As shown in FIG. 1, ES8+ interface communication can be supported between the e-SIM card management platform and the e-SIM card, ES9+ interface communication can be supported between the e-SIM card management platform and the L PD, ES10b interface communication can be supported between the e-SIM card and the L PD, and ES10c interface communication can be supported between the e-SIM card and the L UI.
It should be noted that, the definitions of the ES8+ interface, the ES9+ interface, the ES10b interface, and the ES10c interface may refer to the definitions in the prior art.
As shown in fig. 2, a flow chart of a remote management method of an e-SIM card applied in a remote configuration architecture of the e-SIM card shown in fig. 1 is provided.
Illustratively, a user may first connect to an operator service system in an online or offline manner to perform service handling, and after the service handling is successful, the operator service system sends a configuration file package (profile) generation request to the e-SIM card management platform (corresponding to S11 in fig. 2), where the profile package generation request carries subscription information of the e-SIM card during service handling. Then, the e-SIM card management platform generates a profile package (corresponding to S12 in fig. 2), and sends a generate profile package response (corresponding to S13 in fig. 2) to the operator service system. Finally, the carrier service system may synchronize subscription information of the e-SIM card at the time of service transaction to the trigger server (corresponding to S14 in fig. 2). The ordering information of the service transaction comprises a citizen network electronic identity (eID) and a service order associated with the eID, and the operation type of the Internet of things equipment on the profile, including downloading, activating, inquiring or deleting, is recorded in the service order.
It should be noted that fig. 2 only shows an implementation manner of remote management of an e-SIM card in the prior art, and in practical applications, the implementation manner may also be implemented in other manners. For example, after receiving the request for generating the profile package sent by the operator service system, the e-SIM card management platform may directly synchronize the subscription information of the e-SIM card to the trigger server (corresponding to S15 in fig. 2).
Before downloading, activating, querying or deleting a profile by an internet of things device, the internet of things device first needs to execute L PA instruction, that is, reporting an eID to a trigger server (corresponding to S21 in fig. 2), and then the trigger server queries whether a service order (corresponding to S22 in fig. 2) associated with the eID reported by the internet of things device is recorded, when the trigger server queries the service order associated with the eID, the trigger server causes the internet of things device to report authentication information and perform authentication with each other, after the authentication passes, the trigger server sends a trigger operation request (corresponding to S23 in fig. 2) to the internet of things device, the trigger operation request carries an operation type for the profile, and after receiving the trigger operation request sent by the trigger server, the internet of things device completes a corresponding operation (corresponding to S24 in fig. 2) according to the operation type for the profile carried in the operation request, exemplarily, when the operation type is a download server for the profile, the internet of the device is connected to an e-SIM card management platform, and performs download on an eID package corresponding to the internet of the device (corresponding to the download package of the internet of the profile package of the internet of things device) (25).
The remote management method for the e-SIM card can realize management of a large number of internet of things devices, however, if a large number of internet of things devices execute L PA commands simultaneously in the same cell and perform corresponding operations according to the operation types confirmed when executing L PA commands, the load of the cell can be greatly increased, which causes congestion, especially for access technologies with limited bandwidth, such as narrowband internet of things (NB-IOT) technologies based on cellular, when the internet of things devices share the limited bandwidth to execute L PA commands, not only the operation efficiency of downloading, activating, querying or deleting the profile by the internet of things devices is affected, but also normal services of the cell are affected.
In view of the problems in the prior art, an embodiment of the present application provides a communication method, where before an L PA instruction is executed by an internet of things device, it is necessary to determine whether a priority of communication between the internet of things device and a trigger server at a current time meets a preset condition, and compared with a communication method between an internet of things device and a trigger server in the prior art, a signaling load of a cell network when a large number of internet of things devices initiate requests for executing a L PA instruction at the same time in the same cell can be reduced, thereby avoiding occurrence of a congestion situation.
The communication method provided by the embodiment of the application can be applied to a communication system comprising the Internet of things equipment and the trigger server. Fig. 3 shows a structure of the communication system. As shown in fig. 3, the communication system includes at least one internet of things device 01 and a trigger server 02. The trigger server 02 is connected with each internet of things device 01.
The internet of things device 01 may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a Personal Digital Assistant (PDA), a wearable electronic device, a virtual reality device, and other devices connected to the trigger server 02.
When the internet of things device 01 successfully executes L PA instruction, the internet of things device 01 can perform information interaction with the trigger server 02, that is, communication between the two is realized.
The following describes a communication method provided in an embodiment of the present application with reference to the communication system shown in fig. 3.
In the embodiment of the application, the communication methods between the trigger server 02 and each piece of internet-of-things equipment 01 are the same. The following description will take an example of a communication method between the internet of things device 01 and the trigger server 02.
Referring to fig. 4, a communication method provided in the embodiment of the present application includes S101 to S103:
and S101, calculating the current access grade by the Internet of things equipment.
The current access level is used for representing the communication priority between the Internet of things equipment and the trigger server at the current moment.
The method comprises the steps that the trigger server records the operation type of a configuration file of an electronic card in the Internet of things equipment, wherein the operation type comprises the operations of downloading, activating, inquiring or deleting the profile of the electronic card by the Internet of things equipment.
It should be noted that the electronic card in the embodiment of the present application is an arbitrary identification card that can identify the identity of a user. The electronic card in the embodiment of the present application may be an e-SIM card, for example.
The internet of things equipment can determine the communication priority between the internet of things equipment and the trigger server at the current moment, namely the current access level, through calculation. Illustratively, the internet of things device may first obtain the waiting times, the network environment quality parameters, and the network state levels of the internet of things device, and then calculate the current access level according to the waiting times, the network environment quality parameters, and the network state levels of the internet of things device.
The initial value of the waiting times of the internet of things equipment is zero, and the initial value is used for representing the waiting times of the internet of things equipment waiting for L PA execution.
The network environment quality parameters at least comprise: received Signal Strength Indication (RSSI), Reference Signal Received Power (RSRP), reference signal transmit power, and signal transmission path loss.
When the RSSI is greater than a first preset value, it indicates that the power of a current transmission signal of a cell is higher (i.e., the current load of the cell is higher) or an interference signal of the neighboring cell is higher, or the noise signal is higher, indicating that the current network environment quality is poor, and the internet of things device is not suitable for executing the L PA instruction.
In addition, the quality of the transmission signals of the internet of things equipment can be judged through the RSRP, and when the RSRP is smaller than or equal to a second numerical value, the quality of the transmission signals of the internet of things equipment is poor. For example, the second value may be a difference between a reference signal transmission power of the internet of things device and a signal transmission path loss. The signal transmission path loss may be the maximum path loss that can be supported by the current cell, and in an NB-IOT system, the signal transmission path loss may be 144dB (decibel, a unit of count for measuring signal strength), and in other systems, the signal transmission path loss may take different values according to the requirement of the edge rate. Of course, in practical applications, the second value may also be determined in other manners, for example, in practical applications, when the internet of things device transmits a signal, there are other losses in addition to the signal transmission path loss, which results in a lower received power than the actual value, that is, a worse quality of the transmitted signal. Therefore, the second value may also be a difference between the reference signal transmission power of the internet of things device and the signal transmission path loss, and a second preset value, where the second preset value is a predetermined value representing the transmission signal loss. Illustratively, the second preset value may be 3 dB.
When the internet of things equipment is accessed to the network through the preset number, the internet of things equipment does not have the capacity of transmitting data, namely normal communication cannot be carried out, and only when the internet of things equipment downloads the number belonging to the internet, the internet of things equipment can carry out normal communication.
Illustratively, the current access class may be calculated by expression (1).
laccess＝elRSSI×lRSRP×k+nwait-k+lstatus (1)
Wherein, the access represents the current access level; and the lRSSI represents the RSSI level, the lRSSI takes a value of 0 when the RSSI is greater than a first preset value, and the lRSSI takes a value of 1 when the RSSI is less than or equal to the first preset value. And the lRSRP represents the RSRP access grade, when the RSRP is less than or equal to a second numerical value, the value of the lRSRP is 0, and when the RSRP is greater than the second numerical value, the value of the lRSRP is 1. The lstatus represents the network state grade, when the Internet of things equipment is accessed to the network through the preset number at the current moment, the lstatus takes the value of 1, and the values of other conditions are 0; nwait represents the current waiting times of the Internet of things equipment. In addition, k represents a waiting offset, which is a value determined according to the average load of the network, for example, k may be 2.
In addition, before the internet of things equipment calculates the current access level, whether the internet of things equipment is accessed to the network through the preset number at the current moment can be judged, when the internet of things equipment is judged to be accessed to the network through the preset number at the current moment, the L PA instruction is executed, and when the internet of things equipment is judged not to be accessed to the network through the preset number at the current moment, the current access level is calculated through the expression (2).
laccess＝elRSSI×lRSRP×k+nwait-k(2)
Of course, in practical application, the current access level may also be calculated in other manners according to the number of times of waiting for the internet of things device, the network environment quality parameter, and the network state level, which are not described herein again.
S102, the Internet of things equipment judges whether the current access grade is smaller than a preset grade.
And executing S103 when the IOT equipment judges that the current access grade is greater than or equal to the preset grade.
Specifically, in the expression (1), when the lstatus value is 1, the internet of things device may determine that the current access level is equal to the preset level, that is, s103 may be executed, when the lstatus value is 0, if any one of the lrrp or the lrrssi value is 0, the lrrssi × lrrp × k is 0, at this time, the size of the nwait and the value of k needs to be determined, when k is 2, the current access level may be determined to be greater than or equal to the preset level when the number of times of waiting is 2 or more, that is, s103 may be executed, when the lstatus value is 0, and when both the rsrp and the lrrssi value are 1, the expression (1) is transformed into a lost to enwaitAt this time, it indicates that the current network environment quality is good, and no matter how many times the waiting time is, it may be determined that the current access class is greater than or equal to the preset class, and S103 may be performed.
And S103, the Internet of things equipment executes L PA instructions.
When the internet of things equipment judges that the current access grade is larger than or equal to the preset grade, namely the communication priority of the internet of things equipment and the trigger server at the current moment meets the preset condition of executing the L PA instruction, the internet of things equipment can execute the L PA instruction to perform information interaction with the trigger server at the moment, and the trigger server records the operation type of the configuration file of the electronic card in the internet of things equipment, so the internet of things equipment can perform corresponding operation according to the operation type obtained by the information interaction, the operation after the L PA instruction is specifically executed can refer to the related description of the remote management method for the e-SIM card, and the description is omitted here.
Alternatively, as shown in fig. 5, after step S102, when the internet of things device determines that the current access level is less than the preset level, S104 is performed.
S104, the Internet of things equipment determines that the waiting times of the Internet of things equipment is the sum of the current waiting times and one.
When the internet of things equipment judges that the current access level is smaller than the preset level, it is described that the communication priority between the internet of things equipment and the trigger server at the current moment does not reach the condition that the internet of things equipment executes L PA instructions, the waiting times of the internet of things equipment need to be updated, the step S101 is executed again, and after the step S101, the internet of things equipment executes the step S102 again according to the access level obtained through recalculation.
For example, after the number of waiting times of the internet of things device is updated, a preset timer may be started, the duration of the preset timer is a preset duration, after the preset duration is ended, the access class of the internet of things device is recalculated, and step S102 is executed according to the access class obtained through recalculation.
Optionally, as shown in fig. 5, after step S103, the communication method provided in the embodiment of the present application further includes S105-S108:
and S105, calculating the current execution level by the Internet of things equipment.
Specifically, the internet of things device can calculate a current execution level, wherein the current execution level is used for representing that the internet of things device executes the L PA instruction at most n times under the current access level, and then executes the L PA instruction according to the maximum execution times n corresponding to the current execution level, wherein n is larger than or equal to 1.
For example, the internet of things device may obtain the waiting times, RSRP, and signal to interference plus noise ratio (SINR) of the internet of things device at the current time, and then calculate the current execution level according to the waiting times, RSRP, and SINR of the internet of things device at the current time.
The waiting times and RSRP of the internet of things device at the current moment may refer to the description in the foregoing description of calculating the current access level, and the SINR represents a ratio of the strength of the useful signal received by the internet of things device to the strength of the received interference signal.
Illustratively, the current execution level may be calculated by expression (3).
limple ＝limpeRSRP+lwait (3)
Wherein, the simple represents the current execution level; the lipersrp represents RSRP execution level, and may be determined by expression (4).
Figure BDA0002433751930000101
When the RSRP is less than-105 dBm or the SINR is less than 0dB, the quality of the current network environment is poor, the success rate of executing the L PA instruction can be improved by improving the times of executing the L PA instruction by the Internet of things equipment, when the RSRP is more than or equal to-85 dBm and the SINR is more than 10dB, the quality of the current network environment is good, the failure of executing the L PA instruction by the Internet of things equipment can be caused by other reasons, and the success rate of executing the L PA instruction cannot be improved even if the times of repeated execution are increased.
lwait represents the wait execution level, and can be determined by expression (5).
Figure BDA0002433751930000102
It should be noted that-85 dBm, 10dB, 0dB, and-105 dBm provided in the above embodiments are all parameters determined in advance by human, and in practical applications, the parameter values may be adjusted accordingly according to the network environment, which is not limited herein.
It should be noted that, in practical applications, the sequence of step S105 and step S103 is not limited, that is, after step S102, if the internet of things device determines that the current access level is greater than or equal to the preset level, step S103 may be executed first and then step S105 is executed, or step S105 may be executed first and then step S103 is executed, and in addition, step S105 may also be executed after step S106, when the internet of things device determines that the currently executed L PA instruction fails to be executed.
After the internet of things device calculates the current execution level, it may be determined, with reference to table 1, that the number of times n that the internet of things device corresponding to the current execution level executes L PA instructions at most under the current access level.
