void S1mmeSession::UpdateKqiInfo(S1APNode* p_node) { MsgCommonInfo& common = p_node->GetCommonInfo(); SPUserInfo& sp_user_info = p_node->GetUserInfo(); uint64_t imsi = sp_user_info->GetIMSI(); uint64_t imei = common.imei; uint32_t eci = common.eci == 0 ? sp_user_info->GetEci() : common.eci; uint16_t tac = common.tac; uint64_t last_time = current_time_.tv_sec; //IMSI_T imsi_key(imsi); //IMSI_Iter iter = ue_imsi_map_.find(imsi_key); //LogInfo("%d",common.imei); KqiValue& kqi_value = kqi_map_[imsi]; auto it = kqi_map_.find(imsi); if (it != kqi_map_.end()) { // 如果imsi已存在，则更新其value kqi_value.imsi = imsi; kqi_value.imei = imei; kqi_value.eci = eci; kqi_value.tac = tac; clock_gettime(CLOCK_REALTIME, &kqi_value.last_time); } LogInfo("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!!!!!!"); return; }添加代码，如果imsi不存在就正常添加

可以在`if (it != kqi_map_.end())`语句块之前添加如下代码：

if (it == kqi_map_.end()) {
    // 如果imsi不存在，则创建一个新的KqiValue对象并插入map中
    KqiValue kqi_value_new;
    kqi_value_new.imsi = imsi;
    kqi_value_new.imei = imei;
    kqi_value_new.eci = eci;
    kqi_value_new.tac = tac;
    clock_gettime(CLOCK_REALTIME, &kqi_value_new.last_time);
    kqi_map_.insert({imsi, kqi_value_new});
    return;
}

这样就可以在`imsi`不存在时创建一个新的`KqiValue`对象并将其插入到`kqi_map_`中。完整的函数代码如下：

void S1mmeSession::UpdateKqiInfo(S1APNode* p_node) {
    MsgCommonInfo& common = p_node->GetCommonInfo();
    SPUserInfo& sp_user_info = p_node->GetUserInfo();
    uint64_t imsi = sp_user_info->GetIMSI();
    uint64_t imei = common.imei;
    uint32_t eci = common.eci == 0 ? sp_user_info->GetEci() : common.eci;
    uint16_t tac = common.tac;
    uint64_t last_time = current_time_.tv_sec;

    KqiValue& kqi_value = kqi_map_[imsi];
    auto it = kqi_map_.find(imsi);
    if (it == kqi_map_.end()) {
        // 如果imsi不存在，则创建一个新的KqiValue对象并插入map中
        KqiValue kqi_value_new;
        kqi_value_new.imsi = imsi;
        kqi_value_new.imei = imei;
        kqi_value_new.eci = eci;
        kqi_value_new.tac = tac;
        clock_gettime(CLOCK_REALTIME, &kqi_value_new.last_time);
        kqi_map_.insert({imsi, kqi_value_new});
        return;
    }

    // 如果imsi已存在，则更新其value
    kqi_value.imsi = imsi;
    kqi_value.imei = imei;
    kqi_value.eci = eci;
    kqi_value.tac = tac;
    clock_gettime(CLOCK_REALTIME, &kqi_value.last_time);

    return;
}
