Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail and completely with reference to the following embodiments and accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the communication process, the communication chip often needs to store various data such as a routing table, a configuration table, and the like. Therefore, in general, each type of communication chip will also have a certain memory function. But limited by size and specification, the memory function of the communication chip is very limited, i.e. the memory space that the communication chip can have is small. This limits the communication functions of the communication chip to a certain extent, so that some functions cannot be realized or multiple functions cannot be realized simultaneously.
Currently, a plurality of communication chips, such as an NFC chip, a SIM card, and an eSE chip, are often mounted on mainstream communication equipment. All kinds of communication chips have certain memory function. Along with different use scenes, the occupation conditions of the storage space on various communication chips are often unbalanced. The storage space on a certain communication chip is full, so that the communication function of the communication chip is limited; while other communication chips have a large amount of free memory.
In view of this, the present invention provides a data storage method for a communication chip, which realizes the sharing of storage space among a plurality of communication chips, thereby improving the utilization imbalance of the storage space, and improving the utilization efficiency of the storage space, thereby realizing the expansion of the storage space of the communication chip in a phase-changing manner.
Referring to fig. 1, a data storage method of a communication chip according to an embodiment of the present invention is shown. The method is applied to a first communication chip. I.e. the first communication chip is the executing body of the method. The first communication chip refers to the communication chip that is the requestor in the method. And the opposite second communication chip is used as the communication chip of the requested party. In this embodiment, the method includes the steps of:
The data to be stored is communication data that needs to be stored in this embodiment. Generally, the data to be stored is generated by the first communication chip in the process of executing the communication function, and may be various types of data such as a routing table, a configuration table, and the like. In the prior art, the data to be stored is directly stored in the memory space of the first communication chip itself. However, in this embodiment, in order to achieve the balance of the storage space of each communication chip, one data storage request is generated correspondingly for the data to be stored. Through the data storage request, the storage space of which communication chip the data to be stored is stored in can be further determined.
In this embodiment, the data storage request will satisfy the TLV structure; wherein, T represents an index tag, L represents a data length field of the data to be stored, and V represents a request type field. The specific format is shown in the following table:
| T | L | V |
| index tag | Data length field | And (3) storage request: 1. reading request: 0 |
That is to say, the index tag, the data length field, and the request type field corresponding to the data to be stored may be determined first according to the actual content of the data to be stored. A data storage request is then generated based on the index tag, the data length field, and the request type field.
In addition, based on the same request structure in this embodiment, the specific request type may be a data storage request for storing data or a data reading request for reading data. The value of "store request" in the request type field in the table above is 1, and the value of "read request" is 0, meaning that the type of the request is a data store request.
The data storage request, after being determined, needs to be sent to at least one second communication chip. Typically, the data storage requests are sent to the plurality of second communication chips in sequence.
The second communication chip may determine its own storage state information after receiving the data storage request. The storage state information mainly includes a remaining amount of storage space of the second communication chip. The second communication chip may feed back a response request to the first communication chip if the storage state information of the second communication chip matches the data storage request. And feeding back the response request, which means that the second communication chip agrees to save the data to be stored into the storage space of the second communication chip.
Specifically, the second communication chip may determine the storage status information according to its current available storage space. And if the available storage space and the data length field corresponding to the data to be stored meet the matching condition, determining that the storage state information is matched with the data storage request.
In some cases, if the available storage space is greater than the data length described by the data length field, the two may be considered a match. In other cases, the two may also be considered to match when the available memory space is considered to be greater than the data length described by the data length field and the available memory space of the second communication chip is greater than a certain percentage of the total memory space. Or when the available storage space is larger than the data length described by the data length field and the surplus of the storage space of the second communication chip is still larger than a specific value after the second communication chip stores the data to be stored, the two are considered to be matched. I.e. to ensure that the necessary memory space margin is left for the second communication chip. Regardless of the matching mechanism, the second communication chip feeds back the response request when the storage status information is considered to match the data storage request.
Preferably, when an HCI (Host Controller Interface) communication network is used between the communication chips, the port definition may be performed on the second communication chip according to the ETSI TS 102 v13.0.0 protocol in the field, so as to implement sending of the data storage request to the second communication chip. For example, a Gate ID 0x52 port may be defined by the above protocol to be dedicated to receiving the data storage request.
In particular, the identifier of the second communication chip may be determined first. The identifier may specifically be a unique identifier Hid of the second communication chip in the HCI network. And then determining a corresponding data channel of the second communication chip in the HCI network according to the identifier of the second communication chip. This data channel is the Pipe described in the protocol above. Pipe can be considered as a logical data channel for devices in an HCI network to connect to different functional ports. By utilizing the data channel, the data storage request can be sent to a preset communication port in the second communication chip. The predetermined communication port is also defined as Gate ID 0x52.
Therefore, the data storage request is sent to the second communication chip on the communication layer in the embodiment. Of course, the above should be considered as merely an exemplary implementation. Other methods capable of implementing the same or similar functions may also be combined in the overall technical solution of the present embodiment.
And 103, when the response request meets a preset condition, determining a second communication chip corresponding to the response request as a target communication chip, and storing the data to be stored to the target communication chip.
The first communication chip sends data storage requests to the plurality of second communication chips, so that the response requests received by the first communication chip may not be unique. If a plurality of response requests are received, the response requests meeting the preset conditions need to be further screened out. For example, the first received response request may be considered to satisfy a preset condition.
And then, the second communication chip corresponding to the response request meeting the preset condition can be determined as the target communication chip. The target communication chip, i.e. the destination where the data to be stored is to be saved. That is, after the target communication chip is determined, the data to be stored may be stored in the storage space of the target communication chip.
And step 104, determining a first storage index corresponding to the data to be stored according to the target communication chip, and storing the first storage index.
The data to be stored is not stored in the first communication chip, so that the first communication chip also needs to store a first storage index corresponding to the data to be stored, so as to be convenient for reading the data to be stored from the target communication chip subsequently. Specifically, the first storage index may be determined according to the target communication chip. The specific format of the first storage index is as follows:
| T | L | Hid |
| index tag | Data length field | Identifier of target communication chip |
In contrast, after the target communication chip saves the data to be stored, the target communication chip may also determine a second storage index corresponding to the data to be stored, and save the second storage index, so that the first communication chip may return the data when reading the data to be stored. The specific format of the second storage index is as follows:
| T | L | Hid |
| index tag | Data length field | Identifier of first communication chip |
Therefore, the embodiment realizes the storage of the data to be stored and realizes the storage space sharing among the communication chips in the storage process. According to the technical scheme, the beneficial effects of the embodiment are as follows: the data storage request is sent to the second communication chip, and the data to be stored is stored in the conditional communication chip according to the corresponding response request, so that the sharing of the storage space among the plurality of communication chips is realized, the condition of unbalanced storage space utilization is improved, the utilization efficiency of the storage space is improved, and the expansion of the storage space of the communication chips is realized in a phase-changing manner.
Fig. 1 shows only a basic embodiment of the method of the present invention, and based on this, certain optimization and expansion can be performed, and other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of the data storage method of the communication chip according to the present invention. The embodiment aims at specific scenes that data to be stored needs to be encrypted when being stored in some scenes. In this embodiment, the method includes the steps of:
Since the data to be stored in this embodiment has a security requirement, the data storage request specifically includes an index tag, a data length field, a request type field, and an encryption requirement field. The details are shown in the following table:
| T | L | V（bit0） | V（bit8） |
| index tag | Data length field | And (3) storage request: 1. reading request: 0 | And (4) encrypted storage: 1. and (4) non-encrypted storage: 0 |
In the above table, V (bit 0) represents the request type field. The value of "storage request" in the request type field is 1, and the value of "read request" is 0, which means that the type of the request is a data storage request. V (bit 8) represents an encryption requirement field. The value corresponding to the encrypted storage in the encryption requirement field is 1, and the value corresponding to the unencrypted storage is 0, which means that the data to be stored needs to be encrypted during storage. At this time, it can be considered that the encryption requirement field is a first type field.
Similarly, after receiving the data storage request, the second communication chip needs to determine the storage status information according to its available storage space. And at the moment, the encryption requirement field is the first type field, and then the encryption condition of the second communication chip is required to be determined; i.e. to determine whether the second communication chip has the ability to cryptographically store data to be stored.
And then determining whether the available storage space of the second communication chip and the data length field corresponding to the data to be stored meet the matching condition. And determines whether the encryption condition of the second communication chip itself matches the first type field. In some cases, the encryption condition may be considered to match the first type field if the second communication chip has the ability to cryptographically store data to be stored. In other cases, it may be that a particular encryption algorithm is also specified in the first type field. At this time, it is determined that the second communication chip has the ability to encrypt using the algorithm, and if so, it is determined that the encryption condition matches the first type field.
In this embodiment, if the available storage space and the data length field satisfy the matching condition and the encryption condition and the first type field satisfy the matching condition at the same time, the second communication chip may feed back the response request.
And 203, when the response request meets the preset condition, determining the second communication chip corresponding to the response request as a target communication chip.
The content of this step is the same as that of the related step in the embodiment shown in fig. 1, and the description is not repeated here.
And 204, storing the data to be stored to the target communication chip, and encrypting the data to be stored.
In this embodiment, after the target communication chip stores the data to be stored, the data to be stored needs to be further encrypted.
Similarly, the first communication chip needs to store a first storage index corresponding to the data to be stored. The target communication chip also needs to store a second storage index corresponding to the data to be stored.
It should be noted that, after the data to be stored is saved to the target communication chip by the methods shown in fig. 1 to fig. 2, the method for reading the data to be stored may be as follows:
determining a data reading request according to the target data; sending a data reading request to a corresponding target communication chip according to the first storage index; so that the target communication chip feeds back the target data according to the second storage index.
The target data is the data to be stored which is stored in advance, and is also the data which needs to be read by the first communication chip. When the first communication chip needs to read the target data stored in the target communication chip, a corresponding data reading request needs to be generated first. The data read request is similar to the data store request, and also adopts a TLV structure, which may be specifically shown in the following table:
| T | L | V（bit0） | V（bit8） |
| index tag | Data length field | And (3) storage request: 0. reading request: 1 | And (4) encrypted storage: 1. and (4) non-encrypted storage: 0 |
In the above table, T represents an index tag, L represents a data length field of data to be stored, and V (bit 0) represents a request type field. The value of "store request" in the request type field is 0, and the value of "read request" is 1, meaning that the type of the request is a data read request. V (bit 8) represents an encryption requirement field. The value of "encrypted storage" in the encryption requirement field is 0, and the value of "unencrypted storage" is 1, which means that the target data is encrypted when stored.
After the first communication chip determines the data reading request, a target communication chip where the target data is located can be determined according to a first storage index corresponding to the target data; i.e. to determine the identifier (Hid) of the target communication chip in the first stored index. Based on the identifier, a data read request may be sent to the target communication chip.
After receiving the data reading request, the target communication chip can determine the identifier (Hid) of the first communication chip by the corresponding second storage index of the target data. The target data is then fed back to the first communication chip. And it can be known from the data read request that the target data is encrypted when stored. Before feeding back the target data to the first communication chip, the target data needs to be decrypted.
