GSM signaling network's reliability and availability

GSM signaling network's reliability and availability: I will give you some data through this article on the best way to make the GSM signaling network strong, dependable, and greater available. Some data will be given in extremely short, which will be exceptionally valuable for every one of you. 




In the telecom sector, the reliability and availability of the network is a vital issue, which is dealt with by all service providers. All in all, we can say that the soul of the telecom sector is the network's reliability and availability. Those working in the telecom sector who don't understand the significance of reliability and availability of the network, their jobs are always in harm's way.


Network Reliability 


I never challenge that the data given by me is the best yet can be a lot of value. We need to make the GSM signaling network more dependable, use one E1 line for associating the network elements to one STP. 




Successive LS(Link Set) down because of unstable network condition at the underlying stage of service should be taken considered- 


➤All signaling links associated with the LS would be down when the transmission lines or the facilities are fizzled because there will be just a single physical E1 line accessible between the network elements and the STP. 


➤Lost calls would be normal during the cutover between STPs and the processing load - status of the board work.



Conclusion/Recommendation 


➤Deployment of the other E1 line for those network elements would be recommendable even though there would just be one E1 needed from the dimensioning perspective. 


➤Half of the SLs of a specific network component would be distributed to one of the two E1's, and the rest half of SLs would be assigned to the next E1 line. 


➤It would be suggested that the two E1 lines of a specific network component will be associated with the various STPs respectively. 


Network Availability 


For the Network Availability Co-area of the IP(Intelligent Peripheral)s in ILTs and using 'F' connect for its signaling. 


We as a whole realize that in any network IP has restricted association includes for its signaling links so 10 E1(max), just 1 SL is assignable per E1. Required 2 SLs for association with every system because of its A/A(Active/Active) structure. 


IP is profoundly identified with SCP and SMS(Service Management System) for its working and shares a great deal of DB's with those systems, and IP is interoperated with SCP and SMS through the TCP/IP connect. 


Conclusion/Recommendation 


  • Direct association of IP to the STP would be a better solution for the development of O&M proficiency and network simplicity. 


  • It would be prescribed to co-find the IP with SCP. 


The second most significant issue of network availability is - signaling for Inter MSC. The signaling for Inter MSC - Intra Circle calls will be continued 'F' Links(Associated Signaling Links). 


  • The ILT switches and MSCs will be also associated with the STP. The signal processing heap of the STP for handling the ISUP call processing would be similarly low. 


  • Enter MSCs traffic would be also low because of the "Restricted Mobility" in-network service supplier. 


  • Directly associated signaling join structure for just ISUP call processing between bury MSCs traffic inside a Circle would influence on intricacy and inconsistency of office information, C7 linkage strategy and increase office investment
