可以使用一个 std::unordered_map 来维护这组 key-value 的关系,其中 key 为 imsi,value 为一个结构体,包含了 imsi、imei、common.eci、common.tac、last_time 等信息。每次调用 CtEncodeKqi 函数时,先从 unordered_map 中查找该 imsi 是否已经存在,如果存在则更新该 imsi 对应的 value 值,否则插入一个新的 key-value 对。最后需要注意,当 unordered_map 中的 value 被更新时,需要同时更新 last_time 值为当前时间。

这是一段 C++ 代码,其中定义了一个名为 S1mmeSession 的类,该类包含一个名为 CtOutputKqi 的成员函数。该函数的作用是根据传入的 S1MMEKQI 类型的参数 kqi,向 sp_user_info 对象中填充一些信息,然后根据 kqi 的类型执行不同的功能。具体来说,如果 kqi 的类型是 kS1mmeProcTypeEPSBearerContextDeactivation,则删除释放的承载;如果 kqi 的类型是 kS1mmeProcTypeERABRelease 或 kS1mmeProcTypeERABReleaseIndication,则删除需要释放的承载;如果 kqi 的类型是 kS1mmeProcTypePathSwitch、kS1mmeProcTypeS1SwitchOut 或 kS1mmeProcTypeS1SwitchIn,则删除没有切换过来的承载;如果 kqi 的类型不在 kS1mmeProcTypeAttach 和 kS1mmeProcTypeMax 之间,则直接返回。最后,该函数调用 CtEncodeKqi 函数对 kqi 进行编码,并且更新 test。
void S1mmeSession::CuOutputNode(S1APNode* p_node, uint8_t worker_id,bool timeout) { bool output_ue_release = true, out_put_pdn_connect = true; time_t last_kqi_sec = 0; for (std::vector<CuKqiInfo_T>::iterator it = p_node->cu_kqi_.begin(); it != p_node->cu_kqi_.end();) { CuOutputKqi(p_node, it->msg_type, it->ebi, last_kqi_sec, output_ue_release,worker_id); it = p_node->cu_kqi_.erase(it); } S1MMEKQI* kqi_main = p_node->FindKqi(kS1mmeProcTypeERABModification); if(kqi_main){ CuEncodeErabModification(kqi_main, p_node->GetCommonInfo(), p_node->GetUserInfo(), current_time_.tv_sec,worker_id); } kqi_main = p_node->FindKqi(kS1mmeProcTypeSecondaryRatDataUsage); if(kqi_main){ CuEncodeSecondaryRatDataUsageReport(kqi_main, p_node->GetCommonInfo(), p_node->GetUserInfo(), current_time_.tv_sec,worker_id); } kqi_main = p_node->FindKqi(kS1mmeProcTypeAttach); if (kqi_main && ((timeout && nas_default_encrypt_alg_) || (!timeout))) { S1MMEKQI* kqi_ue_release = p_node->FindKqi(kS1mmeProcTypeUEContextRelease); S1MMEKQI* kqi_pdn_connect = p_node->FindKqi(kS1mmeProcTypePdnConnect, 5); if (1) { for (uint8_t i=0; i<1; i++) { //KQIBearer* p_bearer = kqi_initial_context->GetBearer(i); //if (p_bearer == NULL) break; //p_node->GetUserInfo()->FillKQIBearer(p_bearer->ebi, p_bearer); } } CuEncodeAttach(kqi_main, p_node->GetCommonInfo(), p_node->GetUserInfo(), current_time_.tv_sec,worker_id,kqi_ue_release,kqi_pdn_connect); //output attach if (output_ue_release && kqi_ue_release && kqi_ue_release->complete_time_.tv_sec - kqi_main->complete_time_.tv_sec > 15) { //output UEContextRelease; CuEncodeUEContextRelease(kqi_ue_release,p_node->GetCommonInfo(),p_node->GetUserInfo(),current_time_.tv_sec,worker_id); output_ue_release = false; } out_put_pdn_connect = false; }什么意思
这段代码主要是将S1APNode的信息输出到CU(Control Unit)中。首先,它会遍历p_node->cu_kqi_中的每个CuKqiInfo_T对象,并调用CuOutputKqi()函数将KQI信息编码并输出到CU中。接着,它会查找S1MMEKQI对象,并调用CuEncodeErabModification()、CuEncodeSecondaryRatDataUsageReport()和CuEncodeAttach()函数将ERAB Modification、Secondary RAT Data Usage Report和Attach信息编码并输出到CU中。如果timeout为true且nas_default_encrypt_alg_不为空,还会调用CuEncodeUEContextRelease()函数将UE Context Release信息编码并输出到CU中。在输出Attach信息时,如果output_ue_release为true且kqi_ue_release不为空,且kqi_ue_release已完成的时间与kqi_main已完成的时间相差大于15秒,则会调用CuEncodeUEContextRelease()函数将UE Context Release信息编码并输出到CU中。最后,将out_put_pdn_connect设置为false。
