Description

下载软件的方法和系统 Method and system software download

技术领域 FIELD

[0001] 本发明涉及无线通讯技术领域,更具体地,涉及一种无线接入终端下载软件的方法和系统。 [0001] The present invention relates to wireless communication technology, and more particularly, to a method and system for wireless access terminal to download software.

背景技术 Background technique

[0002]无线接入终端,例如,采用 CDMA 或GSM(Global System forMobile communications)等无线接入方式的无线接入固定台(以下简称固定台),其中有些参数在软件下载后第一次启动时会根据不同的硬件情况进行重新计算(例如:固定台的压控振荡器参数,即VCO参数(Voltage Control Oscillation)等),因此必须在软件下载之前首先获得这些参数的具体数值,并根据实际的数值来判定是否满足下载条件。 [0002] The wireless access terminal, e.g., using CDMA, or GSM (Global System forMobile communications) wireless access fixed wireless access station (hereinafter referred to a fixed station), some of the parameters for the first time after starting the software download will be recalculated based on different hardware (for example: a voltage controlled oscillator fixing table parameters, i.e. parameters VCO (Voltage Control Oscillation), etc.), it is necessary to obtain specific values ​​of these parameters before the first software downloads, and based on the actual value to determine whether conditions meet downloads. 例如VCO参数,在软件下载后第一次启动时,如果参数VCO的数值为0,则会根据本机硬件条件重新计算VCO 数值,这种情况满足下载要求;如果参数VCO的数值不为0,则不会重新计算,这样便导致原来非0参数有可能不是本机硬件条件的参数而出现开机处于离线状态。 For example VCO parameter, the first time after the software download starts, if the parameter value of the VCO is 0, VCO value is recalculated according to the machine hardware conditions, such a download request satisfied; VCO if the value of the parameter is not 0, will not be recalculated, this will lead to the original non-zero parameters may not be the parameters of the machine hardware conditions of the emergence of the boot is offline.

[0003] 因而,需要一种下载软件的方法来在软件下载前确保VCO的数值为0,必须提供一种下载软件的方法,在软件下载到目标机之前就知道VCO等参数的具体数值。 [0003] Accordingly, a need for a method for downloading software to ensure that the value is 0 VCO, must provide a method for downloading software, the software download to know specific numerical values ​​to the VCO parameters before the target before the software download. 而VCO等参数是以文件系统的方式存储在存储器中,但由于文件系统每次运行时的物理地址通常是变化的,所以无法知道VCO等参数存储时的实际物理地址。 The VCO and other parameters are stored in a memory file system, but due to the physical address of the file system each time it runs usually change, it is impossible to know the actual physical address of the VCO and other parameters are stored. 在现有技术中,解决这个问题的办法是文件系统每次构建时的物理地址保持不变(如图1所示),这种方式的弊端是当某个文件被删除时该文件所占用的地址无法继续使用,造成物理空间的严重浪费,这种浪费在无线终端等存储空间非常珍贵的嵌入式设备上是无法允许的。 In the prior art, the solution to this problem is the physical address of the file system each time the building remained unchanged (Figure 1), the drawbacks of this approach is that when a file is deleted the file occupied address can not continue to be used, resulting in a serious waste of physical space, such waste on the wireless terminal and other storage space is at a premium embedded devices is not allowed.

[0004] 因而,急需一种新方式,能够使在文件系统中的每个文件的存储位置是动态变化的,并且文件不是顺序排列的情况下得到特定的参数值,并根据所获得的参数值确定是否进行软件下载。 [0004] Thus, the need for a new way, enabling the storage location of each file in the file system is dynamic, and the resulting specific parameter value if the file is not arranged in order, and the parameter values ​​obtained according to determine whether the software download.

[0030] 以下将参考图3和图4对本发明进行详细说明。 [0030] below with reference to FIGS. 3 and 4 of the present invention will be described in detail. 下载软件前获取参数值的具体实施方法包括以下几个步骤: Obtaining a parameter value before downloading specific software implemented method comprising the following steps:

[0031] 步骤一,在文件系统中的每个文件开始的地方均加一个特定标识,这些特定标识的目的是为了区分系统中不同的文件,是文件名的一种标识。 [0031] Step a, where the beginning of each file in the file system are added to a specific identification, a specific identity for these purposes is to distinguish different file system, a file name identifier. 这个标识是某种特殊的字符串,可以唯一的标识每一个文件,要求字符串的长度不小于10位,例如i^fileri ; This is a particular identification string, the unique identifier for each file, required length of the string is not less than 10, e.g. i ^ fileri;

[0032] 步骤二,在下载之前,首先查找文件系统中每个文件的特定标识所在的位置,即唯一标识每一个文件的特殊字符串的存放位置。 [0032] Step two, before downloading the file system first looks for the location where the specific identity of each file, i.e. storage position special character string uniquely identifies each file. 例如,如图3中的文件2。 For example, file 32 in FIG. 然后,查找文件的特定标识,也就是在系统中查找字符串内容为_打&2_,这个查找字符串的过程是通过“查找单元”来完成的,其中,此单元是通过字符串匹配来实现的。 Then, find the file specific identity, that is, find the string content in the system is playing & _ 2_, the search string is done through the process of "search unit", in which the unit is achieved by matching strings . 另外,在查找到字符串的同时记录下此字符串的具体存放位置,即就是特定标识所在的位置(如图4所示),从而得到文件file2的特定标识的绝对地址A ; Further, in a specific storage location to find the string while the string is recorded, i.e., it is the location where the specific identification (4), to give specific identification file file2 absolute address A;

[0033] 步骤三,根据查找到的特定标识位置和参数在文件中的偏移量(这里参数以VCO 为例,类似参数还有ESN(电子序列号,ElectronicSerial Number)等),找到VCO的物理地址,根据VCO的物理地址取出VCO的实际数值(如图4所示),然后根据步骤二得到的特定标识绝对地址A,并根据VCO的偏移量b,从而计算出VCO的绝对物理地址A+b,从A+b处得到VCO的实际数值;以及 [0033] Step three, according to the found position and the specific identification parameter offset file (VCO parameters here as an example, and the ESN (Electronic Serial Number, ElectronicSerial Number) and the like parameters), to find the physical VCO address, the physical address of the actual value of a VCO of the VCO removed (FIG. 4), and according to a particular absolute address identifier a obtained in step two, and according to the offset VCO, b, to calculate the absolute physical address a VCO + b, to give the actual values ​​from the VCO at the a + b; and

[0034] 步骤四,如果参数VCO的数值为0,则会根据本机硬件条件重新计算VCO数值。 [0034] Step four, if the value of the parameter is 0 VCO, VCO value is recalculated according to the machine hardware.

[0035] 在步骤四中的这种情况满足下载要求,则进行软件下载;如果参数VCO的数值不为0,则不会重新计算,这种情况不满足下载要求,不能进行软件下载。 [0035] In this case satisfy the download request in step four, software download is performed; if the value of the parameter is not 0 VCO is not recalculated, this download request is not satisfied, the software can not be downloaded.

[0036] 在该实施例中,公开了一种在无线接入终端产品上实现软件下载前获取参数值, 实现各种参数对于开发和测试人员全透明,达到出厂时各种参数能完全按照客户需要。 [0036] In this embodiment, there is disclosed a former acquisition parameters downloaded software implemented on the wireless access terminal products, and various parameters for developers and testers transparent, various parameters can be factory reaches full-service need. 本发明在软件下载前获取参数值的方法,思想独特、新颖,简单、易行。 The present invention obtain the parameter values ​​before the software download method, unique ideas, innovative, simple and easy.

[0037] 图5是根据本发明的下载软件前获取参数值的系统的框图。 [0037] FIG. 5 is a block diagram of a system according to the parameter values ​​acquired prior to downloading the software of the present invention. 如图5所示,该系统包括:唯一标识添加单元502,用于在文件系统中的每个文件开始的地方均增加唯一标识; 查找单元504,用于在下载软件前,查找文件系统中的每个文件的唯一标识,并获取唯一标识所在的地址;获取单元506,用于根据唯一标识所在的地址和所需参数在对应文件中的偏移量,计算出所需参数的实际地址,并获取所需参数的参数值;以及判断单元508,用于在获取所需参数的参数值之后,判断参数值是否满足要求,并根据判断结果确定是否进行软件下载。 As shown, the system 5 includes: a unique identifier adding unit 502, where for each file in the file system begins to increase both the unique identification; searching unit 504, prior to downloading software, a file system to find uniquely identifies each file, and acquires the address where the unique identification; obtaining unit 506, according to the address uniquely identify the required parameters and is located offset in the corresponding file, calculate the actual address of the desired parameter, and obtaining the parameter values ​​of the desired parameters; and a determination unit 508, after acquiring the parameter values ​​for the desired parameters, parameter values ​​are determined to meet the requirements, and determine whether to download the software according to the determination result.

[0038] 其中,判断单元508在判断参数值满足要求的情况下,确定进行软件下载,否则不进行软件下载。 [0038] wherein, in a case where the determination unit 508 determines a parameter value to meet the requirements, determining software downloads, software downloads or not.

[0039] 唯一标识是预设的字符串。 [0039] is a preset unique identification string. 字符串的长度不小于10位。 Length of the string is not less than 10.

[0040] 另外,查找单元通过字符串匹配来查找唯一标识。 [0040] Further, a searching unit to search uniquely identified by string matching.
