Http://blog.csdn.net/foolskindom/archive/2009/12/16/5018547.aspx 2.2 IMS entity and Function Description This section describes IMS entities and key functions. These entities can be roughly divided into six categories: session control and routing entity family (cscfs), Database entity (HSS, SLF), and interconnected entity(Bgcf, mgcf, im-MGW, SGW), service-related entities (application server, mrfc, mrfp), supporting entities (thig, seg, PDF), and bill

There are a lot of WLAN and Eutran switch types, the main distinction is a variety of interfaces (such as S2A, S2B, S5, S8), as well as various ways (such as PMIPV6, PIMIP) but for the interface, the basic is the same (I am the terminal test, so the basic value of attention to the interface message) Example: Handover fromtrusted or untrusted non-3gpp IP Access to E-utran with PMIPv6 ons2a or S2B and GTP on S5/S8 interfaces E-utran) "> Step Description: 1. The terminal is connected to a Wi-Fi

Speaking of LTE, we immediately think of the 4G, and when it comes to 4G, many people in the mind is TDD LTE, because our first 4G license is TDD LTE, currently is TDD LTE, operators mainly for China Mobile's dominant. However, with the FDD LTE license soon to be released, C

 Data Warehouse Architecture: Stg-ods-dw-rep/dm/other, Basic dimension date + product. Use the Python language to implement the ETL work of MySQL to Oracle, file landing method. Define HSS functions, program execution portals, define general.py public functions, and develop python.py scripts. Data architecture, each layer based on business design specification rules ETL work, Extract,transform,load, Export file: The database itself exports statem

It is best to define the table of contents form, beautiful and convenient, the following is a definition of a few, you might as well try(1) \def\mla#1#2#3{\par\noindent\hspace*{1 true cm}\parbox[b]{12.3 true cm}{\protect\hspace*{-1 true cm}{#1}\quad{#2}~\dotfill~}\hbox to1.0 true cm{~ (\

unchanged. Of course, this requires the participation of the DNS server. Can all application layer protocols directly obtain the IP address of the final target host, and then enter the IP address in the message for sending? We rely on the DNS server to obtain the IP address of the final target host, but not all application layer protocols use domain names as the routing address, so we cannot obtain the final IP address through the DNS server. Now let's consider an example of a diameter message

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_GW, HSS executables on the same host?So I'll

Currently, traffic revenue is growing rapidly, accounting for about half of the operator's revenue. However, traditional voice communication revenue is still the focus of operators. However, in the 2G or 3G era, there is no obstacle in the 4G era. Complicated VoIP implementation, multiple solutions help LTE transition LTE is a full-IP network, and its network architecture can implement VoIP communication. H

General steps for creating an index in solrj: 1) create a solrserver object, which is used to manage indexes. 2) create a solrinputdocument object, that is, a document object, and add fields to the Document Object. 3) use the Add method of the solrserver object to add the solrinputdocument object and create an index. 4) Call The COMMIT () method of the solrserver object to submit the index. For example: Httpsolrserver HSS = new httpsolrserver ("http:

, TDD spectrum may become an important reserve resource for future business traffic development. Taking the UK market as an example, UK Broadband's 3.5 GHz LTETDD spectrum resources of MHz can also provide sufficient bandwidth for future mobile data businesses. As business traffic demand increases, it may become the target of major operators. At the same time, TDD Systems naturally have flexible asymmetric transmission capabilities, which can better adapt to the asymmetric characteristics of mob

1, what is the 4G network? How fast is 4G speed faster than 3G? 4 G is the fourth generation of mobile communication technology, it integrates 3G and WLAN in one, and can transmit high-quality video images and with High-definition television comparable. The popular point is that using mobile phones to surf the internet faster, the theoretical speed can reach 100Mbps, about 12.5mb/s. It is 2000 times times faster than dial-up, 3-5 times faster than the 3G we now use, and is comparable to WiFi. F

Difficulties to be solved for commercial acceleration of carrier Aggregation The increase in network coverage and the popularity of wireless applications bring a good user experience, and the willingness of users to use 4G services is also increasing. According to statistics, LTE users consume GB of data traffic per month on average, almost twice the usage of non-LTE users. Various novel wireless applicati

other functions, to promote the first rapid development of mobile data Services, the realization of mobile communication technology and data communication technology (especially Internet technology) perfect combination. GPRS is a technology between 2G and 3G, also known as 2.5G . It also has a younger brother Edge, known as 2.75G. They lay the groundwork for a smooth transition from GSM to 3G. 3G: The third generation of mobile communication technology, refers to the support of high-spe

with an HMAC. HMAC is formed in this way: first, a data structure is established, which includes Alice's temporary value, Bob's temporary value, their identification, and shared secret key KAB; then hash the data structure and the hash result is HMAC. When Alice received message 2, she now had the identity of Ra, Rb, both sides, and secret key KAB, so she could also calculate HMAC. if the calculated HMAC is the same as the HMAC in the message, she knows that she is talking to Bob. Alice also

Go to your own blog early, and save it for future blocking. Single radio voice call continuity (srvcc) srvcc is an LTE functionality that allows a VoIP/IMS call in the LTE packet domain to be moved to a legacy voice domain (GSM/UMTS or CDMA 1X ). consider a case where a new LTE network operator wants to move voice services to VOIP over IMS in conjunction with the

People often associate the application with a fixed venue when speaking of HD video conferences. However, just in the Shanghai World Expo Park area of China Mobile TD-LTE integrated business demonstration car, reporters found such a no need to connect to the high-definition video conference room cable: 65 inch on the high-definition display, whether in China Mobile Expo communication command center, theme pavilion mobile HD conference room, or even ta
