It is arranged in the equipment being connect with Internet of Things, this method includes: the step of LPA is executed
As shown in connection with fig. 1,
S110: downloading data is received；The downloading data is letter of application of the server according to the Profile downloading received
What breath generated, the downloading data includes multiple Profile data blocks；
Step S110 is executed on the basis of being built upon the application information for issuing Profile downloading with user orientation server,
Specifically, the application information of Profile downloading, the letter of application that server is downloaded according to Profile are issued with user orientation server
Breath determines Profile downloading data, and after determining, downloading data is sent to LPA.Wherein, user can be by Internet of Things
Downloading Profile button is clicked in user interface in equipment, after downloading Profile button is clicked, is issued to server
The application information of Profile downloading.Certainly, Profile data file can form multiple Profile data blocks here.
S120: each Profile data block in multiple Profile data blocks is converted one by one, obtains multiple lists
Multiple singles or cascading update short message file instruction perhaps cascading update short message file instruction and are sent to eSIM card by item,
So that eSIM card downloads Profile by multiple singles or cascading update short message file instruction.
It is understood that LPA is converted into single or cascade when receiving downloading data, by Profile data block
Then obtained single or cascading update short message file instruction are sent to eSIM card, eSIM card by more new message file instruction
By single or cascading update short message file instruction, Profile is downloaded.From the aforegoing it can be seen that the present invention not receives LPA
Profile data block directly passes through APDU (Application Protocol Data Unit) instruction Store Data and issues ISD-R to carry out
Profile downloading, but by being converted into more new message file instruction, it is downloaded by way of more new message file
Profile avoids the limitation due to mould group and leads to the case where downloading Profile failure.
Wherein, Profile data block is converted into single or cascading update short message file instruction, it can be understood as, one
Profile data block is converted into single or cascading update short message file instruction, and multiple Profile data blocks are converted into multiple lists
Item or cascading update short message file instruction.Specific change over condition can regard specific change data length, processing capacity etc.
Depending on.
The following present a Profile data blocks how much quantity is converted according to data length and processing capacity
Short message file instruction.Specifically each Profile data block in multiple Profile data blocks is converted one by one, is obtained
The step of multiple singles or cascading update short message file instruction includes:
One by one using each Profile data block in multiple Profile data blocks as current Profile data block:
(1) current Profile data block is split, obtains current single or cascade data store instruction.
Since Profile data block may include multiple data, the length of each data block and of different sizes can basis
Limitation of the eSIM card to data length in the processing capacity of data and a data store instruction (Store Data instruction), will work as
Preceding Profile data block split into preset length single or a plurality of cascade data, then by the single of preset length or
The a plurality of cascade data organization of person is at current single or cascade data store instruction.It is then organized into if it is single data default
One Store Data of length is instructed, and if it is a plurality of cascade data, is then organized into a plurality of Store of preset length
Data instruction.Wherein, preset length can be 255 bytes.
(2) by the current single, perhaps cascade data store instruction is converted to obtain current single or cascade more
New message file instruction.
Wherein, each Store Data instructs (instruction data storage) corresponding conversion at single or cascading update short message
File instruction, cascade Store Data instruction are converted into cascading update short message file instruction.
The present invention before the step of the multiple single or cascading update short message file instruction are sent to eSIM card,
Further include:
The storage file in eSIM card is selected, single or cascading update short message file instruction are sent in eSIM card
Storage file in.
For example, the 6F3C file under the selection storage common 7F10 file of short message.It, will after then having selected storage file
A plurality of more new message file instruction is successively sent to the 6F3C file under the 7F10 file in eSIM card, can update same provision
Part record can also be different item.
