qcmap底层基于高通的数据服务接DSI接口
DSI：Data Service Interface，数据业务接口
netctrl：网络控制
bring up / tear down：数据呼叫通道的建立、销毁
APN：Access Point Name，移动接入点名称
PDN：Packet data network，包数据网络（分组业务网络）
DNS：Domain Name Service，域名解析服务
Qos：Quality Of Service，业务质量控制
QMI：Qualcomm Messaging Interface，高通消息传递接口
本库启动的时候作为一个守护进程，底层依赖QMI提供功能，客户端启动进程后调用本库连接守护进程处理数据业务。
本库提供：
1. WWAN数据业务的建立、销毁和基本配置，可以配置APN、IP协议族、技术选择优先级、用户名密码、profile ID等
2. Qos（DSI_NetCtrl provides methods for applications to request UE-initiated QoS）
3. 多播和多媒体多播
4. DNS（Domain Name Service）
5. 各种数据业务状态查询
6. 支持双IP数据呼叫，客户端只要使用单个接口即可，不用连接两次
7. 支持多PDN同时建立数据业务，应用程序必须控制路由
8. 支持多个进程连接DSI_NetCtrl，每个进程可以独立控制数据连接的建立和销毁，多PDN场景也可以用多个进程处理
【数据呼叫流程】
1. dsi_init，初始化，客户端连接到守护进程
2. dsi_start_data_call，设置数据连接参数，启动数据连接，启动前可以配置多次，可以配置的参数包括：
2.1 UMTS / CDMA ID
2.2 APN
2.3 IP Version （IPv4 / IPv6/ IPv4v6）
2.4 APN用户名密码
2.5 认证优先级
2.6 技术类型 / 扩展技术名称
3. dsi_stop_data_call，销毁数据连接（同时网络侧可能发起数据连接销毁，此时将网络状态通知到dsi进程）
【Qos】
主要功能：
流量监管（对进入接口的，超出限制速率的报文进行丢弃）
流量整形（对接口发送的，超出限制速率的报文先进行缓存，等待流量不超出速率时发送）
拥塞避免（在出现网络拥塞时对符合条件的报文进行丢弃）
拥塞管理（在出现网络拥塞时采用队列调度的方法对符合条件的队列中的报文优先发送）
流策略（可根据不同的流分类实现诸如禁止/允许通过，重标记报文优先级、重标记报文VLAN标签、重定向流量、过滤报文、
流量镜像、启用流量统计功能等行为）。
dsi库支持用户发起的和网络侧发起的Qos。
【qcmap】
9X07模块提供了qcmap_msgr服务来进行拨号，通过与dsi_netctrl对比，qcmap_msgr接口更清晰，而且操作也简单。
AP侧使用QMI架构和modem通信初始化流程是固定的：
qcmap_msgr_get_service_object_v01查询服务对象 =>qmi_client_notifier_init初始化client通知信息 =>qmi_client_get_service_list查询支持的服务列表个数 =>qmi_client_get_service_list查询支持的服务列表信息 =>qmi_client_init使用其中一个服务信息初始化client
参考代码：
void qcmap_ppp_init(qcmap_ppp_t *self,client_status_ind_t client_cb_ind) {
qmi_idl_service_object_type qcmap_msgr_qmi_idl_service_object;
uint32_t num_services = 0, num_entries = 0;

if (qcmap_msgr_qmi_idl_service_object == NULL)
{

return;
}
qmi_error = qmi_client_notifier_init(qcmap_msgr_qmi_idl_service_object,

&self->qmi_qcmap_msgr_notifier);

{

/* The server has come up, store the information in info variable */
qmi_error = qmi_client_get_service_list(qcmap_msgr_qmi_idl_service_object,
info,
&num_entries,
&num_services);
LOG("qmi_client_get_service_list: num_e %d num_s %d error %d", num_entries, num_services, qmi_error);
if (qmi_error != QMI_NO_ERR)
{

self->qmi_qcmap_msgr_notifier = NULL;
LOG("Can not get qcmap_msgr service list %d",
qmi_error);
return;
}
qmi_error = qmi_client_init(&info[0],
qcmap_msgr_qmi_idl_service_object,
client_cb_ind,
NULL,
NULL,
&self->qmi_qcmap_msgr_handle);
LOG("qmi_client_init: %d", qmi_error);

self->qmi_qcmap_msgr_notifier = NULL;
LOG("Can not init qcmap_msgr client %d", qmi_error);
return;
}
}
对应释放过程比较简单，主要是释放client初始化信息:
static void qcmap_ppp_uninit(qcmap_ppp_t *self) {
qmi_client_error_type qmi_error;
assert(self);
qmi_error = qmi_client_release(self->qmi_qcmap_msgr_notifier);
self->qmi_qcmap_msgr_notifier = NULL;
if (qmi_error != QMI_NO_ERR)
{
LOG("Can not release client qcmap notifier %d",qmi_error);
}
qmi_error = qmi_client_release(self->qmi_qcmap_msgr_handle);
self->qmi_qcmap_msgr_handle = NULL;
if (qmi_error != QMI_NO_ERR)
{
LOG("Can not release client qcmap handle %d",qmi_error);

}
至此，就可以完成拨号的连接和断开。
2.3 PPP状态
如果关注状态通知，需要处理知函数client_cb_ind中状态通知。主要包含了建立拨号成功/失败，网络状态变化（切换网络模式）的断开通知等。
static void qcmap_ppp_ind(
qmi_client_type user_handle,
unsigned int msg_id,
void *ind_buf,
unsigned int ind_buf_len,
void *ind_cb_data )
{
qmi_client_error_type qmi_error;
LOG("qcmap_msgr_qmi_qcmap_ind: user_handle %X msg_id %d ind_buf_len %d.", user_handle, msg_id, ind_buf_len);
}
2.4 建立连接可选项
- 禁用ipv6

qcmap_msgr_disable_ipv6_resp_msg_v01 qcmap_disable_ipv6_resp_msg;
qmi_client_error_type qmi_error;
/* Enable IPV6. */

}

}
- 配置自动连接(没测试出效果)
