Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communications method and apparatus.
Background
Most of the terminals of the internet of things support cellular communication technology and do not support other communication technologies such as Bluetooth or wireless high-fidelity (wireless fidelity, WIFI) and the like. For such terminals, a preset code number is required, based on which the terminal can download the electronic card. However, each terminal is configured with a preset code number, so that the terminal is helped to realize the initial network connection to complete the downloading of the electronic card, a large amount of code number resources are occupied, and the waste of the code number resources is brought. The code number multiplexing method can save code number resources, and the code number multiplexing method refers to: the unit time is divided into the same number of access time slots and download time slots, and different access time slots with the same preset code number are allocated to different terminals, so that a plurality of terminals share one preset code number.
In the existing preset code number multiplexing method, one access time slot can only be used by one terminal, but the frequency of using the access time slot by most terminals is low, so that most access time slots are idle for a long time, and waste of access time slot resources is generated.

Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" means two or more.
First, the technology related to the embodiment of the present invention will be described:
referring to fig. 1, fig. 1 illustrates a remote configuration architecture of an embedded subscriber identity module (embedded subscriber identification module, eSIM) card, including a code number management system, an eSIM card service acceptance and download trigger server (abbreviated as trigger server), an eSIM card management platform, and a communication module of the eSIM card. The code number management system is a subsystem in the business system of the operator and is mainly responsible for distributing code numbers to the eSIM cards and managing the eSIM cards. The triggering server can trigger the internet of things device to complete downloading, activating, inquiring or deleting of a user subscription data set (profile) of the eSIM card based on the eSIM card management platform when communicating with the internet of things device. The eSIM card management platform comprises an eSIM card data generation server and an eSIM card download server, and is responsible for generating, storing and managing profile data and executing functions such as profile downloading and the like. LPA is a software package in the communication module of the eSIM card that includes a local profile download (local profiledownload, LPD) and a local user interface (local user interface, LUI). In addition, CI is a certificate and EUM represents the vendor that produced the eSIM card.
As shown in fig. 1, the eSIM card management platform and the eSIM card may support ES8+ interface communication, the eSIM card management platform and the LPD may support ES9+ interface communication, the eSIM card and the LPD may support ES10b interface communication, and the eSIM card and the LUI may support ES10c interface communication.
Note that, the definitions of the above-mentioned ES8+ interface, ES9+ interface, ES10b interface, and ES10c interface may refer to the definitions in the prior art.
As shown in fig. 2, a flow diagram of a method for remote management of eSIM cards applied in the remote configuration architecture of eSIM cards shown in fig. 1 is provided.
For example, a user may first connect to an operator service system through an online or offline manner to perform service handling, and after the service handling is successful, the operator service system sends a profile package (profile package) generating request (corresponding to S11 in fig. 2) to the eSIM card management platform, where the profile package generating request carries subscription information of the eSIM card during service handling. Then, the eSIM card management platform generates a profile package (corresponding to S12 in fig. 2) and sends a generate profile package response to the carrier service system (corresponding to S13 in fig. 2). Finally, the carrier business system can synchronize the subscription information of the business-handling eSIM card to the trigger server (corresponding to S14 in fig. 2). The subscription information of the business transaction comprises an electronic identity (electronic identity, eID) and a business order associated with the eID, wherein the business order records the operation type of the internet of things equipment on the profile, including downloading, activating, inquiring or deleting and the like.
It should be noted that fig. 2 only shows one implementation manner of remote management of eSIM cards in the prior art, and in practical application, the implementation manner may be other ways. Illustratively, after receiving a profile package generating request sent by the carrier business system, the eSIM card management platform may directly synchronize subscription information of the eSIM card to the trigger server (corresponding to S15 in fig. 2).
Before the internet of things device downloads, activates, inquires or deletes the profile, the internet of things device first needs to execute the LPA instruction, that is, reports eID to the trigger server (corresponding to S21 in fig. 2), and then the trigger server inquires whether a service order associated with the eID reported by the internet of things device is recorded (corresponding to S22 in fig. 2). When the trigger server queries the service order associated with eID, the trigger server can enable the Internet of things equipment to report authentication information and mutually perform authentication, after the authentication is passed, the trigger server can send a trigger operation request to the Internet of things equipment (corresponding to S23 in FIG. 2), the trigger operation request carries an operation type of profile, and after receiving the trigger operation request sent by the trigger server, the Internet of things equipment completes corresponding operation according to the operation type of profile carried in the operation request (corresponding to S24 in FIG. 2). For example, when the operation type is downloading the profile, the internet of things device connects to the eSIM card management platform through the trigger server, and downloads a profile package associated with eID of the internet of things device in the eSIM card management platform (corresponding to S25 in fig. 2).
The embodiment of the invention provides a communication method which is used for solving the problem that part of terminals cannot communicate when moving out of the coverage range of the current operator.

In a specific implementation, embodiments of the present invention are not particularly limited to a particular form of communication device 100. The communication device 100 may be the code number management system.
The communication method provided by the embodiment of the present invention is described below with reference to the communication device 100 shown in fig. 3.
As shown in fig. 4, the communication method provided by the embodiment of the present invention includes:
s401, the communication device 100 acquires the target value n of the terminal.
Wherein the target value n of the terminal is related to the identity of the terminal.
The communication device 100 may directly acquire the target value n of the terminal. The communication device 100 may also acquire the identity of the terminal first, and then determine the target value n of the terminal according to the identity of the terminal.
The identity of the terminal includes, but is not limited to, eID of the terminal. The following describes embodiments of the present invention by taking an eID of a terminal as an example.
n is a positive integer. n satisfies the formula: (x+10y+100z) mod (N/2), x is the first last bit of the terminal eID, y is the second last bit of the terminal eID, and z is the third last bit of the terminal eID.
S402, the communication device 100 inquires about the allocation state of the access sub-time slot ns of the A-th preset code number.
Wherein A is a positive integer. s is a positive integer.
The access sub-slot ns is the s-th access sub-slot of the n-th access slot. For example, access sub-slot n1 is the 1 st access sub-slot of the nth access slot.
Each access slot includes M access sub-slots.
M is a positive integer. M satisfies the formula:
T access to access the length of the time slot, T download For the length of the download slot.
T download The formula is satisfied: t (T) download ＝T/N。
T is a unit time T, which may be an integer multiple of 0.5, for example, 0.5 hours, 1.0 hours, 1.5 hours, etc.
N is the number of time slots per unit time T.
N satisfies the formula:
k satisfies the formula:
r is the average rate in kilobits per second (kbps) that can be achieved at the minimum allocated resource unit of the network. For example, an average rate that can be achieved at 1 Resource Block (RB) in a long term evolution (long term evolution, LTE) system.
k is a correction factor, k is an integer greater than or equal to 1, when the network load is light, the average allocated resource number of the terminal is greater than the minimum resource unit, and the correction is carried out through k, 1 is taken by default, and the lower the network load is, the larger the value of k is.
P is the electronic card profile packet size in kilobytes (KByte).
For example, referring to fig. 5, a unit time T is divided into N slots, and each slot is numbered according to the sequence of the slots, wherein the first slot is numbered 0 and the nth slot is numbered N-1. The time slots are divided into odd time slots and even time slots according to the labels of the time slots. The odd number of slots are denoted as download slots (slot numbered 1, slot numbered 3, slot numbered 5, … …, slot numbered N-1, download slot 2, download slot 3, … … download slot N/2). The even number of time slots are denoted as access time slots (time slot numbered 0, time slot numbered 2, time slot numbered 4, … …, time slot numbered N-2, access time slot 1, access time slot 2, access time slot 3, … … access time slot N/2) as access time slots. Each access slot is divided into M sub-slots. For example, access slot 1 is divided into access sub-slot 11, access sub-slot 12, access sub-slots 13, … …, and access sub-slot 1M.
S403, the communication device 100 allocates the access sub-slot ns of the a-th preset code number to the terminal when the access sub-slot ns of the a-th preset code number is not allocated.
Illustratively, A is 1 and s is 1. The communication device 100 allocates the access sub-slot n1 of the 1 st preset code number to the terminal in the case where the access sub-slot n1 of the 1 st preset code number is not allocated.
As can be seen from the above-described S401 to S403, one access slot can be used by only one terminal, compared to the existing slot multiplexing method. The embodiment of the invention further divides the access time slot into a plurality of access sub-time slots, and then distributes different access sub-time slots of the same access time slot to different terminals, so that different terminals can use different access sub-time slots of the same access time slot. Therefore, the utilization rate of the access time slot resources is improved, and the problem that the utilization rate of the access time slot resources is lower in the existing preset code number multiplexing method is solved.
Referring to fig. 4, as shown in fig. 6, the communication method provided by the embodiment of the present invention further includes:
s404, when the access sub-time slot ns of the A-th preset code number is allocated and A is not equal to the first threshold value, the communication device 100 updates A to be A+1, and inquires about the allocation state of the access sub-time slot ns of the A-th preset code number.
Wherein, the initial value of A is 1, and the initial value of s is 1.
The first threshold is the same as the number of preset code numbers. For example, there are 1000 preset code numbers, and the first threshold is 1000.
It should be noted that, the access sub-slot ns of the a-th preset code number is already allocated, a is not equal to the first threshold, which means that the access sub-slot ns of the current preset code number is already allocated to other terminals and cannot be allocated to the terminal any more, so that the allocation situation of the access sub-slot ns of the next preset code number is to be queried (i.e. update a to a+1 and query the allocation status of the access sub-slot ns of the a-th preset code number) if the current preset code number is not the last preset code number (i.e. a is not equal to the first threshold). If the access sub-slot ns of the next preset code number is not available and the preset code number is not the last preset code number, the allocation of the next preset code number is queried again, and so on until an unallocated access sub-slot is found.
For example, there are 1000 preset code numbers in total, and the communication device 100 queries the access sub-slot ns of the 2 nd preset code number if the access sub-slot ns of the 1 st preset code number is allocated. If the access sub-time slot ns of the 2 nd preset code number is not allocated, the access sub-time slot ns is allocated to the terminal. If the access sub-slot ns of the 2 nd preset code number is allocated, the access sub-slot ns of the 3 rd preset code number is queried. And so on until an unassigned access sub-slot is found.
It should be noted that S404 may be understood that the communication device 100 updates a to a+1 when the access sub-slot ns of the a-th preset code number is allocated and a is not equal to the first threshold value. And then S402 is performed again.
S405, the communication device 100 updates A to 1 and S to s+1 when the access sub-time slot ns of the A-th preset code number is allocated and A is equal to the first threshold value, and inquires about the allocation status of the access sub-time slot ns of the A-th preset code number.
It is worth mentioning that the access sub-slot ns of the a-th preset code number is allocated, and a is equal to the first threshold. It is explained that the access sub-slot ns of the current preset code number has been allocated to other terminals and cannot be allocated to that terminal anymore, and that the current preset code number is the last preset code number, i.e. the access sub-slots ns of all preset code numbers have been allocated to other terminals. Therefore, the allocation of the next access sub-slot of the first preset code number is queried (i.e. update a is 1 and update s is s+1). If the access sub-slot ns of the next preset code number is not available and the preset code number is not the last preset code number, the allocation of the next preset code number is queried again, and so on until the unallocated access sub-slot is found.
For example, there are 1000 preset code numbers in total, and the communication device 100 queries the access sub-slot n2 of the 1 st preset code number if the access sub-slot n1 of the 1000 th preset code number is allocated. If the 1 st access sub-time slot n2 with the preset code number is not allocated, the terminal is allocated. If the access sub-slot n2 of the 1 st preset code number is allocated, the access sub-slot n2 of the 2 nd preset code number is queried. And so on until an unassigned access sub-slot is found.
It should be noted that S405 may be understood that when the access sub-slot ns of the a-th preset code number is allocated, and a is equal to the first threshold, the communication device 100 updates a to 1 and updates S to s+1. And then S402 is performed again.
S406, the communication device 100 periodically updates the allocation status of the access sub-slot.
Wherein the interval T time is updated twice.
Specifically, S406 includes:
the status of the allocated access sub-slots is periodically updated to unassigned.
The state of the previous access sub-slot of the allocated access sub-slot is periodically updated to be allocated.
It should be noted that S406 may advance each access sub-slot except the first access sub-slot by one bit every T times. To ensure that each terminal is assigned an access sub-slot that is located at the first position of the access slot.
Illustratively, referring to tables 1 and 2, 1 indicates that an access sub-slot has been allocated, and 0 indicates that an access sub-slot has not been allocated. Table 1 shows the allocation status of the current access sub-slot. Table 2 shows the allocation status of the access sub-slots after the T time. As can be seen from tables 1 and 2, each access sub-slot except the first access sub-slot is shifted forward by one bit every T times.
For example, the state of the access sub-slot 12 in table 1 is unassigned, and the state of the access sub-slot 11 in table 2 is the same (i.e., unassigned). That is, the access sub-slot 11 in table 2 is the access sub-slot 12 before the T time, i.e., the access sub-slot 12 in table 1.
For another example, the state of the access sub-slot 13 in table 1 is allocated, and the state of the access sub-slot 12 in table 2 is the same as the state (i.e., allocated). That is, the access sub-slot 12 in table 2 is the access sub-slot 13 before the T time, i.e., the access sub-slot 13 in table 1.
TABLE 1
TABLE 2
Specifically, the position Paccess (n) of the current access sub-slot of the terminal satisfies formula 1:
equation 1:
paccess (n) is the current access sub-slot of the terminal, and Paccess (n-1) is the access sub-slot position of one unit time (i.e. T) on the terminal.
For example, M is 1000, and the access sub-slot of the terminal with a unit time is the access sub-slot 3. Since 3+.1, the current access sub-slot of the terminal can be calculated as access sub-slot 2 (i.e., 3-1) according to equation 1.
For another example, M is 1000, and the access sub-slot of the terminal with a unit time is the access sub-slot 1. Since 1=1. The current access sub-slot of the terminal may be calculated as the access sub-slot 1000 (i.e., M) according to equation 1.
It should be noted that, in the case that the electronic card is not successfully downloaded by using the downloading time slot, the terminal may calculate the next access sub-time slot by using equation 1, and re-apply for using the downloading sub-time slot when the next access sub-time slot is used.
In addition, the terminal can calculate the current access sub-slot through the following formula, without calculating the current access sub-slot every T time.
Equation 2:
tm is the current position.
tm satisfies the formula:
v is the current position of the terminal, and the unit is hours.
V satisfies the formula: v= (T-T0) mod (mxt).
t0 is the time at which the communication device 100 notifies the terminal of the starting slot per unit time when the preset code number is allocated. t is the terminal access time.
It should be noted that if the calculated current access sub-slot does not arrive, when the access sub-slot arrives, the terminal requests to use the next download slot at the Paccs (n) th access sub-slot of the access slot to which the terminal belongs, if the current access sub-slot has passed, the Paccs (n) next access sub-slot position is calculated by formula 1, and when the next unit time arrives, the terminal requests to use the next download slot at the Paccs (n) th access sub-slot of the access slot to which the terminal belongs.
