The genuine ouc.exe file is a software component of Enhanced Mobile Switching Center (EMSC) by Huawei Technologies Co., Ltd..
The "Online Update Client" is part of the software installed from Huawei's USB mobile Internet modem dongles alongside the "Connection Manager" and "Mobile Partner". It is known to install registry RUN keys which cause it to start automatically when Windows boots up, and to act as the computer on the Internet with system privileges. It can be uninstalled by running the "uninst.exe" program from the folder it installed in, which is usually a subfolder containing the ISP's name and possibly the name "UpdateDog" beneath that. Its name suggests that it looks for available updates of the USB modem's software and downloads them, however this is not clearly stated. Huawei Technologies Company is in Shenzhen, Guangdong Province, in mainland China and claims to supply mobile Internet service and associated devices to nearly one-third of the world's people. (One vendor of its USB modem sticks advertises that there are so many different Internet provider names on them that it ships at random whichever are in stock.) Huawei is also known to have close ties to China's military which has caused multiple countries' governments to ban use of their products for official communications.
