How to run Oaisim with virtual MME in same machine (example_oaisim_enb_ue_mme_virtual)Since I don ' t have much knowledge on EPC and MME, just follow the example file (Example_oaisim_enb_ue_mme_virtual.txt) to Make a test? The example file has such a configuration,according to Lionel gauthier.this example shows what to generate and launch ENB, 1 UE (NAS still not virtualized in UE) in virtualised mode, MME_

In recent years, the increasing demand for mobile data services has promoted the acceleration of LTE network commercialization. Throughout the world, LTE commercial networks are still dominated by lte fdd, but with the gradual development of their networks, users and businesses are increasing, lte fdd network frequency

4G TDD-LTE and FDD-LTE two models, do you understand? At present, there are two 4G standards based on LTE, namely lte fdd and lte tdd (China is used to call lte tdd TD-LTE, both stand

Currently there are two 4G standards based on LTE, namely LTE FDD and LTE TDD (the domestic custom of LTE TDD is called Td-lte). See the name you will have an intuitive impression, the two standards are based on the different branches of

Understanding CS fallback in LTE LTE technology supports packet based services only, however 3GPP does specifies fallback for circuit switched services as well. To achieve this LTE architecture and network nodes require additional functionality, this blog is an attempt to provide overviewFor same. In LTE architecture,

China's LTE commercialization is approaching, and the industry's attention to the subsequent evolution of LTE has reached a new peak. Compared with 3G, LTE significantly improves the spectrum efficiency. However, the industry has not stopped. A few years ago, 3GPP began to research and develop the LTE-Advanced standard

LTE beginners, if you also for the LTE self-study and confused;LTE scholars, if you're still worried about the effectiveness of LTE learning,If you want to learn LTE well instead of simply learning about LTE,To make

is equivalent to extending the S1 interface between the family base station and the core network, so that more family base stations can be configured in the system. We can think that the family base station gateway is used to centralize the control layer C-Plane), especially a concentrator of the S1-MME interface gateway module. The S1-U interface at the home base station end can be terminated at the home base station gateway or through the direct us

The Charm Clan MX5 cracked unicom/Mobile 4g/3g (TD-LTE/TD-SCDMA/FDD-LTE/WCDMA) Prerequisite: To ensure adequate electricity, at least 50%. Use pea pods, application treasure, etc. to back up important information. 1, download MX5 General edition firmware (http://www.flyme.cn/firmware.html) 2, after downloading, the handset and the computer through the data line connection. Hint: The screenshot b

-frame is to allow the terminal to decode the downlink dispatch information at an early stage (the translator note: The terminal can know how to decode the Dl-sch information), so that the terminal before the end of the sub-frame transmission can be Dl-sch demodulation and decoding, reduce dl-sch decoding delay, This reduces the delay of the overall downstream transmission. More importantly, the control domain is placed at the beginning of the sub-frame, then those non-scheduled terminals do not

switch command to the UE. After receiving the switch, the UE switches and synchronizes the switch to the target eNB. The network responds to the synchronization. After the UE successfully accesses the target eNB, send a switch confirmation message to the target eNB. C. Switching completed: MME sends a user-side update request to the S-GW, and the user-side switches the downstream path to the target side; the target eNB notifies the source eNB to rele

, and the dwpts length of 2nd half frames is 1 ms. Uppts and sub-frame 2 are used as the uplink, and sub-Frames 7 and 9 are used as the downlink.Physical resources Basic time unit Antenna Port LTE uses antenna ports to differentiate space resources. The definition of an antenna port is defined from the receiver's perspective. That is, if the receiver needs to distinguish the difference in space between resources, multiple antenna ports need to be d

In December 5, Wei leping, director of China Telecom Technology Commission, said that after China Telecom obtained a 4G license, it will coordinate the coordinated development of LTE and FTTH and give full play to its respective advantages ~ In the past 10 years, LTE and FTTH will be two major technical levers for China Telecom. In terms of 4G network planning, China Telecom will first adopt TDD and FDD hyb

Layered Structure of LTE air Interfaces Layered Structure of LTE air Interfaces LTE air interface layer structure, and WCDMA air interface layer structure is the same, from top to bottom is also divided into several layers of RRC-PDCP-RLC-MAC-PHY, RRC belongs to the network layer, PDCP, RLC and MAC belongs to the link layer, PHY belongs to the physical layer.
