Talk:GSM services

message: I think I read elsewhere on Wikipedia that in the UK, the caller pays different rates for calls to mobile phones than landlines, which is why all mobile numbers have a different prefix.  Here in the US, cell phone subscribers pay for their airtime.  Callers pay the same rates for calls to mobile and fixed phones, and there are usually no special prefixes.  For US subscribers, roaming simply means they may be charged more for their airtime, unless they have free roaming on their plan.  I think I'll convert the "Roaming" section into a general "Charges" section.  Someone should please add info about the different charges in the UK and other countries if that's correct. -- Beland 12:31, 9 Jan 2005 (UTC)
thread_title: Voice charges

message: OK, so this article now makes a lot of sense and seems really helpful, but it seems to have outgrown its title.  It not only describes the various services than GSM provides, but also the elements in the GSM system and several event sequences.  It seems to me that a more appropriate title would be something like, "How GSM works".  I like the suggestion of relegating description of the network components to GSM core network and GSM protocols.
Remaining todo items, then:
* Create and add diagrams to this page
* Clean up GSM core network and GSM
* Write GSM protocols

replies: text: I assumed that this page was about Suplimentary Services offered by GSM providers.  I think that content related to GSM architecture belongs in Base Station Subsystem and Network Switching Subsystem, but I don't know where call flow comes into the picture then.  Each of those subsystems is certainly large enough to warrent its own article. Cacophony 07:54, 23 December 2005 (UTC)
thread_title: Article coordination

message: I've noticed that if someone calls me when I've turned my phone off, it goes straight to my voicemail. However, if my phone loses a signal because it goes out of range, the other party still hears a ring--but it's a different ring than is heard when I'm within range and my phone is ringing. In fact, if I move within range while the third party is hearing the ring pattern, they will hear a change in the ring pattern when my cell picks up the ring signal.
So it appears the GSM standard incorporates a method of determining if a particular mobile station (phone) has powered down or has simply temporarily moved out of range. Furthermore, the MSC or Gateway MSC is able to determine the difference and create a different ring pattern based on which condition is in effect.
It appears that someone who has experience in engineering a GSM system has contributed to this article. Can that person (or people) put something in this article addressing this?

thread_title:  Copyright problem removed 

message: advice of charge is a general phone network feature. It is present in GSM but also in various ISDN standards. I would even argue that it originated from there. 
Why is is it forwarded to GSM in English Wikipedia? Wefa (talk) 18:27, 2 July 2022 (UTC)
