Communication method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication method and device.

Background

Most terminals of the internet of things support cellular communication technologies and do not support other communication technologies such as bluetooth or wireless fidelity (WIFI). For such terminals, a preset code number is required, and the terminal can download the electronic card based on the preset code number. However, each terminal is configured with a preset code number, so that the terminal is helped to realize initial network connection to complete electronic card downloading, and meanwhile, a large amount of code number resources are occupied, and waste of code number resources is brought. The code number multiplexing method can save code number resources, and the code number multiplexing method is as follows: 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 download time slot can only be used by one terminal, but some terminals can only use half or even less download time slots to complete the download, so that the remaining time of the download time slot occupied by the terminal after the terminal completes the download is not transmitted with any data, and cannot be used by other terminals, thereby generating the waste of download time slot resources.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the present invention, the meaning of "a plurality" means two or more unless otherwise specified.

First, a description is given of a technique related to an embodiment of the present invention:

referring to fig. 1, fig. 1 illustrates a remote configuration architecture of an embedded subscriber identity module (eSIM) card, which includes a code number management system, an eSIM card service acceptance and download trigger server (trigger server for short), an eSIM card management platform, and an eSIM card communication module. The code number management system is a subsystem in the operator service system and is mainly responsible for allocating code numbers to the eSIM cards and managing the eSIM cards. The trigger server can trigger the internet of things device to download, activate, query or delete 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 the functions of profile download and the like. The LPA is a software package in the communication module of the eSIM card, and includes a Local Profile Download (LPD) and a Local User Interface (LUI). In addition, CI is a certificate, and EUM denotes a vendor that produces eSIM cards.

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.

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 flowchart of a remote management method for an eSIM card applied to the remote configuration architecture of an eSIM card 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 transaction, and after the service transaction is successful, the operator service system sends a request for generating a profile package (profile package) to the eSIM card management platform (corresponding to S11 in fig. 2), where the request for generating the profile package carries subscription information of the eSIM card during service transaction. Then, the eSIM card management platform generates a profile package (corresponding to S12 in fig. 2), and transmits a generate profile package response (corresponding to S13 in fig. 2) to the carrier service system. Finally, the carrier business system may synchronize subscription information of the eSIM card at the time of business transaction to the trigger server (corresponding to S14 in fig. 2). The order information of the service transaction comprises an electronic identity (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 eSIM card in the prior art, and in practical applications, the implementation manner may also be implemented in other manners. For example, after receiving the profile package generation request sent by the operator service system, the eSIM card management platform may directly synchronize the subscription information of the eSIM card to the trigger server (corresponding to S15 in fig. 2).

Before the internet of things device downloads, activates, queries or deletes the profile, the internet of things device first needs to execute an LPA instruction, that is, report the eID to the trigger server (corresponding to S21 in fig. 2), and then the trigger server queries 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 the eID, the trigger server enables 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 the internet of things device receives the trigger operation request sent by the trigger server, the internet of things device completes a corresponding operation according to the operation type for the profile carried in the operation request (corresponding to S24 in fig. 2). Illustratively, when the operation type is downloading of a profile, the internet of things device is connected to the eSIM card management platform through the trigger server, and a profile package associated with the eID of the internet of things device in the eSIM card management platform is downloaded (corresponding to S25 in fig. 2).

The following describes a communication method provided by an embodiment of the present invention with reference to the communication device 100 shown in fig. 3.

As shown in fig. 4, a communication method provided in an embodiment of the present invention includes:

s401, the communication device 100 receives a download slot use request.

Wherein, the request for using the download time slot includes the CQI of the terminal.

The download slot use request is reported through an access slot n, wherein n is a positive integer.

n satisfies the formula: (x +10y +100z) mod (N/2), x being the first to last digit of the terminal eID, y being the second to last digit of the terminal eID, and z being the third to last digit of the terminal eID.

S402, the communication device 100 determines the number Y of the downloading sub-time slots required by the terminal according to the CQI of the terminal.

Wherein Y is a positive integer. Y satisfies the formula:

TBSmax' is the maximum resource block size that can be achieved when the electronic card is occupied to download the evenly distributed resources. The electronic card downloading average distribution resource can be obtained through simulation (the electronic card downloading average distribution resource obtained through simulation may be different due to different load conditions and different service models of cells in different areas). For example, the electronic card download average allocated resource of a Long Term Evolution (LTE) system is 6 Physical Resource Blocks (PRBs), the system bandwidth is 20M, and the TBSmax' is 4392 from table 7.1.7.2.1-1 in 3rd generation partnership project (3 GPP) 36.213.

Beta is a resource allocation correction coefficient, when a system is close to full load when busy hour or instantaneous traffic is large, the beta value is larger than 1, the higher the system load is, the larger the beta setting is, when the system load is lower than 70% when idle hour or traffic is small, the beta value is smaller than 1, and the lower the system load is, the smaller the beta setting is.

η is a Multiple In Multiple Out (MIMO) correction coefficient.

η satisfies the formula: eta is Lmax/L. Lmax is the maximum number of paths for space division multiplexing. And L is the maximum number of paths which can be reached by the terminal in the MIMO mode under the current CQI.

The Transport Block Size (TBS) is the TBS size when the average number of resources is occupied.

Illustratively, the communication device 100 determines 3 download sub-slots required for the terminal based on the CQI for the terminal.

Specifically, taking the LET system as an example, S402 includes:

the communication apparatus 100 obtains a modulation and coding scheme Index (IMCS) of the terminal from the CQI of the terminal.

The setting range of the IMCS, MCSindex, is defined to be "0" to "28". In addition, the initial value of "MCSIndex" is set to "5". When the value of Modulation is changed, the set value of MCSIndex is also changed in conjunction with the change.

The communication device 100 obtains a transport block size Index (ITBS) of the terminal from the IMCS of the terminal.

The communication apparatus 100 determines the TBS of the terminal according to the ITBS of the terminal.

S403, the communication device 100 issues the first indication message when the download time slot n is occupied and there are Y consecutive available download sub-time slots in the download time slot n.

The first indication message is used for indicating the terminal to download the electronic card by using Y available download sub-time slots in the download time slot n.

It should be noted that, referring to fig. 5, a unit time T is divided into N time slots, and a label is given to each time slot according to the sequence of the time slots, where the label of the first time slot is 0, and the label of the nth time slot is N-1. The slots are divided into odd slots and even slots according to their labels. The odd slots are denoted as download slots (slot number 1, slot number 3, slot number 5, … …, slot number N-1, as download slot 1, download slot 2, download slot 3, … … download slot N/2). The even slots are denoted as access slots (slot number 0, slot number 2, slot number 4, … …, slot number N-2, access slot 1, access slot 2, access slot 3, … … access slot N/2). 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-slot 13, … …, access sub-slot 1M.

And the terminal in different access sub-time slots of the same access time slot can use the download time slot corresponding to the access time slot. Therefore, a terminal in different access sub-slots of the same access slot may request to use the download slot corresponding to the access slot at the same time. In this case, the communication device 100 may first allocate a download sub-slot in the download slot to the terminal that has first sent the request and update the status of the download slot to occupied. The terminal that later makes the request can only use the download sub-slot (i.e., the available download sub-slot) that is not used by the previous terminal in the download slot.

Illustratively, there are 10 download sub-slots in download slot n. Wherein, the download time slot n is occupied, the 1 st to 7 th download sub-time slots in the download time slot n are unavailable, and the 8 th to 10 th download sub-time slots are available. Since there are 3 consecutive available download sub-slots (8 th to 10 th download sub-slots) in the download slot n, the communication apparatus 100 terminal downloads the electronic card using the 3 consecutive available download sub-slots in the download slot n.

It can be seen from the foregoing S401-S403 that, compared with the existing preset code number multiplexing method in which one download time slot can only be used by one terminal, the communication method provided in the embodiment of the present invention further divides the download time slot into a plurality of download sub time slots, and enables the terminal to download the electronic card through the remaining download sub time slots of the download time slot when the download time slot is occupied but there are continuously available download sub time slots. Thereby realizing that a plurality of terminals share different sub-time slots of one download time slot. Therefore, the resource utilization rate of the download time slot is improved. The problem of low resource utilization rate of the download time slot in the existing preset code number multiplexing method is solved.

Referring to fig. 4, as shown in fig. 6, the communication method provided in the embodiment of the present invention may further include:

s404, the communication device 100 issues the second indication message when the download time slot n is not occupied.

And the second indication message is used for indicating the terminal to download the electronic card by using the first Y download sub time slots of the download time slot n.

S405, the communication device 100 issues the third indication message when the download time slot n is occupied and there are no consecutive Y available download sub-time slots in the download time slot n.

And the third indication message is used for indicating the terminal to report the download time slot use request in the next access time slot n.

S406, the communication device 100 divides each download slot into D download sub-slots.

Wherein D is a positive integer. D satisfies the formula:

tdownload is the length of the download slot in milliseconds (ms).

tdownload' is the intermediate amount of the length of the download sub-slot, and the unit is ms.

Tdownload satisfies the formula: tdownload 1000/N.

T is unit time in seconds. When T is set, the timeliness and the code resource utilization rate need to be balanced, the code resource utilization rate is improved, the T value can be increased, the N value is increased, and the number of terminals reusing the same number is more; however, if the terminal fails to apply for using the next download timeslot in the access timeslot n, the terminal needs to re-apply for T time, and if the T value is set to be larger, the terminal can re-apply for a longer time interval, and the terminal has poor timeliness for completing the code number. When the code number resource is rich, the T value can be reduced, and the waiting time of the terminal is shortened. The value of T may be set by default to 3600 seconds (i.e., 1 hour).

N satisfies the formula:

k satisfies the formula:

p is the electronic card profile packet size in kilobytes (Kbyte).

Rmin is the minimum rate that the terminal can reach when occupying the electronic card to download the evenly distributed resources.

k is a correction factor and is an integer greater than or equal to 1, when the network load is light, the number of resources allocated by the terminal is greater than the average allocated resource unit, the correction is carried out through k, 1 is selected by default, and the value of k is larger when the network load is lower.

It is worth mentioning that k is different from β in that k is used for correcting long-term load, for example, when a new station of a system is built, the load is light, and as the number of users increases, the load increases, the value of k should be properly reduced; and beta is used for responding to short-time load change, for example, the load is increased in busy hours, and the terminal can not distribute the average number of resources, so that more downloading sub-time slots are obtained by increasing beta to ensure that the electronic card downloading is successfully completed.

Alpha is a MIMO correction factor. α satisfies the formula: and alpha is Lmin/Lmax. When the wireless environment is not good, MIMO usually operates in a reception diversity mode, and there is no space division multiplexing gain, Lmax is the maximum number of channels for space division multiplexing, Lmax is 2 for 2 × 2MIMO, and Lmax is 4 for 4 × 4 MIMO.

Rmin satisfies the formula: rmin TBSmin' Rmax/TBSmax.

Rmax is the peak rate of the terminal when all resources of the cell are occupied, and can be a simulation value or an actual peak value obtained from a network management system.

TBSmax is the maximum resource block size that can be achieved by occupying all resources, for example, the bandwidth of an LTE system is 20M, and the TBSmax is 75376 obtained from table 7.1.7.2.1-1 look-up in 3gpp 36.213.

tdownload' satisfies the formula:

tdownload’＝(TBSmax*P*8)/(TBSmax’*Rmax)。

the length of the download sub-slot can be denoted tdownload in ms.

tdownload satisfies the formula: tdownload is Tdownload/D.

The scheme provided by the embodiment of the invention is mainly introduced from the perspective of a method. To implement the above functions, it includes hardware structures and/or software modules for performing the respective functions. Those of skill in the art will readily appreciate that the present invention can be implemented in hardware or a combination of hardware and computer software, with the exemplary elements and algorithm steps described in connection with the embodiments disclosed herein.
