2G, 3G interoperability testing

2G, 3G interoperability Cisco Catalyst 3560 and upgrading work is at present operators need to complete the work,the interoperability working smoothly?

● coverage based switching, service based switching and load based switching and other advanced algorithm, can effectively guarantee the continuity of the 3G, and make full use of the existing 2G cyber source, to maximize the performance of 3G mobile user experience.

The software system, test system using the framework of the same, all network standard,according to the module is loaded, the user can choose the corresponding module combination,can achieve a variety of network support functions.

Lu Xiao: with the improvement of 2G network, 3G network continuous input, 2G/3G network willcoexist for a long time, then 2G, 3G interoperability and upgrading work are also operatorsattach great importance to work, but in the early stage of 3G development, operators have been aware of this problem, technical requirement on operators, 2G/3G interoperability is a very important index.

Japanese technology products, has been the spirit of 2G to 3G smooth upgrade of the goal, to achieve the interoperability of 2G/3G upgrade. In order to test system NTASPROFESSIONAL as an example, can support TDSCMA/WCDMA/CDMA1X/GSM/GPRS/EDGE 2G/3G network system, software system using the framework of the same, all network system, are in accordance with the module is loaded into it, the user can choose the corresponding modulecombination, can achieve a variety of network support functions. In early 2006, TD-SCDMA is still in the test period, rising technology will help operators to complete the TD-SCDMA and GSM at the same time comparison test work in Baoding, help operators to better analyze and understand the differences between two kinds of networks and problems.

Chen Ding: the first time realized the TD 2G/3G voice switching in 2007 April, interoperableproducts have full 2G/3G support. In 2007 September, system interoperability testing in a mobile group of 2G/3G interoperability, 2G system is connected with the Nokia Siemens and Ericsson and other manufacturers of TD TD system conducted a comprehensive verification of 2G/3G interoperability, satisfactory results have been achieved. The early construction of TD network, GSM/GPRS network covering a wide range, TD network general services in regional hot spots or key city, TD system provides coverage based switching, service based switching and load based switching and other advanced algorithm, can effectively guarantee the continuity of the 3G, and make full use of the existing 2G cyber source, maximum limit to improve the 3G mobile user experience.

Tao Xiongqiang: Putian as early as 2007 had successfully completed the development of theproperty, and in 2007 August passed the test of the Ministry of information industry and China Mobile Group respectively, the successful completion of the terminal and core network IOT test.Marking equipment TD system has been completely Putian 2G/3G switching function, to meet the needs of large-scale commercial operators.

Huang Yue: for network interoperability, Datang Mobile 3G network fully support all needed functions, and already and mobile GSM network equipment providers completed interoperability testing.Cisco 3560 Switch
