逆向解析 ColorOS 离线号码库 (一)：12-Bit 极限压缩的归属地查询算法#

0. 前言#

最近在开发一个项目时，需要用到中国大陆电话号码归属地以及运营商查询的 API。在调研了网络上现有的 API 后，我发现它们要么存在严格的并发限制和 API Key 双重校验，要么底层的数据库不够完整和准确。

但我们平时使用的智能手机，在没有网络的情况下依然能在来电几毫秒内准确显示号码归属地，它们是如何做到的？与其依赖受限的网络 API，不如直接从手机系统自带的拨号软件中提取离线数据库。

1. 理论依据与通用架构#

在原生的 Android 系统中，来电归属地等本土化功能其实比较薄弱。但国内的手机厂商（如 OPPO、小米、vivo 等）都基于此构建了一套非常成熟的 “本地离线查询 + 云端辅助” 机制。

这类系统实现“归属地与运营商”查找的通用技术架构一般如下：

a. 核心原理：基于“号段”的离线映射

中国大陆的手机号码分配有着严格的规律。通常，前 3 位决定了基础运营商，而前 7 位决定了具体的地级市归属地和运营商细分。厂商会在系统级的核心应用（如 ContactsProvider.apk 或独立的 Telephony 服务）中内置一个高度压缩的离线数据库（通常是 .db、.dat 格式或自定义的二进制文件）。

号段示例 (前7位)	运营商	归属地
138 0010	中国移动	北京
186 0210	中国联通	上海
189 0200	中国电信	天津

b. 代码层面的查询流程

当我们在拨号盘输入号码，或者收到来电时，系统的跨进程查询流程通常如下：

提取特征：系统前端首先清洗输入的号码（去除 +86、空格、破折号等格式字符），然后截取前 7 位核心号段。
IPC 跨进程通信：UI 层不会直接去读取底层离线文件，而是通过构建特定的 Uri，向系统的底层内容提供者（ContentProvider）发起查询请求。
底层解析返回：底层的服务应用接收到请求后，通过查表或特定算法解析二进制数据文件，将计算出的“归属地”和“运营商”字段打包，原路返回给 UI 层进行渲染显示。

2. 寻找并定位离线数据库#

以我所使用的设备 OPPO Find X6（ColorOS 16.0 系统） 为例。

通过在系统中进行关键词检索，我很快定位到了专门负责处理归属地逻辑的系统应用——号码归属地 (com.oplus.phonenoareainquire)。幸运的是，作为系统内建的基础服务，该应用并未进行深度的加固或高强度混淆，这为我们的静态分析提供了极大的便利。

提取并解压该应用的 APK 文件后，在 /assets 目录下，我如愿以偿地找到了两个核心数据文件：

PhoneNumberData_3_1_0.dat (归属地数据库)
CarrierData_1_0.dat (运营商数据库)

本节我们先将目光聚焦在归属地文件 PhoneNumberData_3_1_0.dat 上。

不出所料，使用普通的文本编辑器打开它后是一堆乱码。为了让系统在极短的时间内完成检索，厂商并没有使用纯文本或标准的 SQLite 格式，而是采用了一种自定义的高强度压缩二进制数据结构。

不过，通过分析文件底层的字节流，我们依然能窥探到一些明文线索：

文件头 (Header)：文件最开头明文存储了一串数字 817820250424。在大多数安卓号段库中，这通常代表着数据库的版本号或最后更新的编译时间戳。
数据字典区 (Tail)：在文件靠后的尾部数据区，清晰地暴露出了中国大陆的城市长途区号及地名（采用 GBK 编码）。例如：010、020、021（分别对应北京、广州、上海），以及成百上千个地级市的区号。

3. 提取读取规则与字典表#

既然无法直接阅读，那没招了，试试 Jadx 逆向吧。

在 Jadx 中全局搜索字符串 "PhoneNumberData_3_1_0.dat"，很快定位到了负责初始化的 PhoneNoInquireDatabaseHelper.java 类。在它的 c() 方法中，揭示了文件头部的读取规则：

1
public void c(SQLiteDatabase sQLiteDatabase, String str) throws Throwable {

2
    File fileA = b.a(PhoneNoInquireProvider.f300w);
3
    InputStream inputStreamOpen = this.f740d.getResources().getAssets().open("PhoneNumberData_3_1_0.dat");
4
    FileOutputStream fileOutputStream = new FileOutputStream(fileA);
5
    byte[] bArr = new byte[102400];
6
    Log.i("PhoneNoDbHelper", "copy PhoneNumberData.dat to /data/data/");
7
    while (true) {
8
        int i3 = inputStreamOpen.read(bArr);
9
        if (i3 == -1) {
10
            break;
11
        } else {
12
            fileOutputStream.write(bArr, 0, i3);
13
        }
14
    }
15
    inputStreamOpen.close();
16
    fileOutputStream.close();
17
    FileInputStream fileInputStream = new FileInputStream(fileA);
18
    DataInputStream dataInputStream = new DataInputStream(a(fileInputStream));
19
    byte[] bArr2 = new byte[12]; // 读取前 12 个字节作为版本号
20
    int i4 = dataInputStream.read(bArr2, 0, 12);
21
    String str2 = new String(bArr2, "UTF-8"); // 对应我们看到的 817820250424
22
    Log.i("PhoneNoDbHelper", "version =" + str2 + ", versionLength = " + i4);
53 collapsed lines
23
    try {
24
        ContentValues contentValues = new ContentValues();
25
        contentValues.put("ver", str2);
26
        sQLiteDatabase.insert("version", null, contentValues);
27
    } catch (Exception e3) {
28
        Log.e("PhoneNoDbHelper", BuildConfig.FLAVOR + e3);
29
    }
30
    File fileA2 = b.a(PhoneNoInquireProvider.f301x);
31
    InputStream inputStreamOpen2 = this.f740d.getResources().getAssets().open("ExtendNumber.dat");
32
    FileOutputStream fileOutputStream2 = new FileOutputStream(fileA2);
33
    while (true) {
34
        int i5 = inputStreamOpen2.read(bArr);
35
        if (i5 == -1) {
36
            break;
37
        } else {
38
            fileOutputStream2.write(bArr, 0, i5);
39
        }
40
    }
41
    inputStreamOpen2.close();
42
    fileOutputStream2.close();
43
    f(dataInputStream, sQLiteDatabase);
44
    File fileA3 = b.a(PhoneNoInquireProvider.f302y);
45
    InputStream inputStreamOpen3 = this.f740d.getResources().getAssets().open("city_name_table.txt");
46
    FileOutputStream fileOutputStream3 = new FileOutputStream(fileA3);
47
    while (true) {
48
        int i6 = inputStreamOpen3.read(bArr);
49
        if (i6 == -1) {
50
            break;
51
        } else {
52
            fileOutputStream3.write(bArr, 0, i6);
53
        }
54
    }
55
    inputStreamOpen3.close();
56
    fileOutputStream3.close();
57
    d(sQLiteDatabase);
58
    try {
59
        h(sQLiteDatabase);
60
    } catch (Exception e4) {
61
        Log.e("PhoneNoDbHelper", "updateCityCode fail " + e4);
62
    }
63
    try {
64
        b.b(new File(PhoneNoInquireProvider.f303z));
65
        OplusLocaleChangeJobIntentService.n(PhoneNumberAreaApplication.b("Multi_Language_Table.txt", PhoneNoInquireProvider.f303z), this.f740d, sQLiteDatabase, str);
66
    } catch (Exception e5) {
67
        try {
68
            OplusLocaleChangeJobIntentService.n(null, this.f740d, sQLiteDatabase, str + "-Exception");
69
        } catch (Exception e6) {
70
            Log.e("PhoneNoDbHelper", "e = " + e6);
71
        }
72
        Log.e("PhoneNoDbHelper", "e = " + e5);
73
    }
74
    fileInputStream.close();
75
}

更关键的是用于解析字典表的 f() 方法。代码展示了它是如何通过跳过核心数据区，直接读取尾部的城市字典的：

1
    private void f(DataInputStream dataInputStream, SQLiteDatabase sQLiteDatabase) throws IOException {
2
        byte[] bArr = new byte[2];
3
        byte[] bArr2 = new byte[2000];
4
        byte[] bArr3 = new byte[8000];
5
        byte[] bArr4 = new byte[2000];
6
        dataInputStream.skip(dataInputStream.available() - 12002); // 直接跳到文件末尾的倒数 12002 字节处
7
        dataInputStream.read(bArr); // 数量标识
8
        dataInputStream.read(bArr2); // 区号区
9
        dataInputStream.read(bArr3); // 城市名区
10
        dataInputStream.read(bArr4); // 扩展标记区
4 collapsed lines
11
        if (f738e) {
12
            Log.d("PhoneNoDbHelper", "cityNum:" + ((bArr[1] & 255) | (bArr[0] << 8)));
13
        }
14
        Log.d("PhoneNoDbHelper", "start insert areano_and_citynames table");
15
        for (int i3 = 0; i3 < 400; i3++) {
16
            try {
17
                String strTrim = new String(bArr2, i3 * 5, 5).trim();
18
                String strTrim2 = new String(bArr3, i3 * 20, 20, "gbk").trim();
24 collapsed lines
19
                if (strTrim.equals(BuildConfig.FLAVOR) && strTrim2.equals(BuildConfig.FLAVOR)) {
20
                    break;
21
                }
22
                sQLiteDatabase.execSQL("insert into areano_and_citynames(areano,cityname) values ('" + strTrim + "','" + strTrim2 + "');");
23
            } catch (Exception unused) {
24
                Log.e("PhoneNoDbHelper", "init database failed");
25
                return;
26
            }
27
        }
28
        SharedPreferences.Editor editorEdit = this.f740d.getSharedPreferences("expand", 0).edit();
29
        editorEdit.clear();
30
        for (int i4 = 0; i4 < 1000; i4++) {
31
            int i5 = i4 * 2;
32
            int i6 = (bArr4[i5] & 255) << 8;
33
            int i7 = bArr4[i5 + 1] & 255;
34
            if (i6 == 0 && i7 == 0) {
35
                break;
36
            }
37
            editorEdit.putString(Integer.toString(i4), Integer.toString(i6 + i7));
38
        }
39
        editorEdit.commit();
40
        dataInputStream.close();
41
        Log.d("PhoneNoDbHelper", "init database sucess");
42
    }

通过上述代码，我们可以清晰地得出尾部字典的结构：

bArr2：存放了 400 个区号，每个固定占 5 个字节（需执行 .trim() 去除空格）。
bArr3：存放了 400 个城市名称，每个固定占 20 个字节（需使用 GBK 解码）。
bArr4：1000 个 16 位的扩展号段标记。

遗憾的是，当试图查看最核心的查询方法 l() 和初始化号码树的方法 F() 时，Jadx 提示 Method dump skipped。由于方法体过长或逻辑过于复杂，反编译引擎放弃了转换。无奈之下，只能硬着头皮去阅读底层的 Smali 汇编指令。

阅读 Smali 代码后发现，在 F() 方法中，系统构建了一个名为 this.a 的 HashMap。这个 Map 存放的是手机号前三位（基础号段）对应的内存基础偏移量。

代码通过循环，为 130-139、150-159 以及 188、189 等基础号段分配了递增的偏移值。例如：

130 对应偏移量 0
131 对应偏移量 10000
132 对应偏移量 20000

随后，它还会从尾部的扩展区中读取诸如 170、199 等较新的号段，并将它们同样补充进该 HashMap 中。

4.2 号段的数学映射模型 (`l()` 方法)#

当系统需要查询一个具体的号码（例如 13812345678）时，l() 方法的剥离与寻址逻辑如下：

提取核心：截取前 7 位，得到 1381234。
拆分前后缀：前缀 Prefix = 138，后缀 Suffix = 1234。
计算绝对索引：去 HashMap 中查到 138 的基础偏移量（假设为 80000）。将其与后缀转换为的整数相加：绝对索引 = 80000 + 1234 = 81234。

4.3 精妙的 12-Bit 极限压缩算法#

拿到绝对索引后，如何去庞大的二进制流中取出归属地 ID？通常，表示一个城市的 ID 至少需要一个 short (16位/2字节)。但为了将千万级号段的数据体积压缩到极致，工程师为每个城市 ID 仅分配了 12 个 Bit (1.5 字节)。因为全国地级市不到 400 个，最大 ID 只需要 12 位二进制（最大可表示 4095）便绰绰有余。

为了将两个 12-Bit 的数据严丝合缝地塞进 3 个字节（24 bits）里，底层进行了绝妙的位移运算（Bitwise Shift）。将 Smali 代码还原为 Java 逻辑如下：

1
int remainder = index % 2;
2
int baseIndex = (index / 2) * 3; // 因为每 2 个数据共占 3 个字节
3

4
// 连续读取 3 个字节
5
int b1 = this.b[baseIndex] & 0xFF;
16 collapsed lines
6
int b2 = this.b[baseIndex + 1] & 0xFF;
7
int b3 = this.b[baseIndex + 2] & 0xFF;
8

9
int cityId;
10
if (remainder == 0) {
11
    // 偶数索引：取第1个字节的全部 + 第2个字节的前4位
12
    cityId = (b1 << 4) | (b2 >> 4);
13
} else {
14
    // 奇数索引：取第2个字节的后4位 + 第3个字节的全部
15
    cityId = ((b2 & 0x0F) << 8) | b3;
16
}
17

18
// cityId 为 0 时表示未知归属地
19
if (cityId == 0) {
20
    return null;
21
}

拿到解密后的 cityId 后，直接将其作为索引，去步骤 3 中提取出的城市字典列表中查找，即可完美获得该号码的对应城市与区号。

5. Python 算法重构#

基于以上的逆向分析，我们完全脱离了 Android 环境，使用纯 Python 实现了对该二进制数据文件的脱机解析与查询。完整代码如下：

1
import os
2

3
def load_database(file_path):
4
    print("⏳ 正在加载并解析底层数据库...")
5

18
        # 解析城市名 (GBK编码，遇 \x00 截断)
19
        name_bytes = city_names_raw[i*20 : i*20+20].split(b'\x00')[0]
20
        name = name_bytes.decode('gbk', errors='ignore').strip()

6. 阶段总结与预告#

至此，我们已经成功解决了字典的内存偏移规则、精妙的 12-Bit 压缩解密算法，以及尾部城市的解析方式，完成了号码归属地的逆向重构。

不过，你可能会发现，这套方案目前只能查到归属城市，还缺少至关重要的“运营商”信息。在下一节中，我们将继续深挖同目录下的 CarrierData_1_0.dat，揭开运营商识别的底层多级指针寻址机制，敬请期待！
