Do all know the Internet TCP, HTTP, so mobile phone calls and text messages between the use of what is the agreement? Is there any agreement nouns can search?

Mobile communication involves many interfaces and nodes, therefore involves many protocols, the communication technology and mobile phone use also have relations, in the case of LTE, two users with voice calls involving the agreement includes: air interface PHY, MAC, RLC, PDCP, RRC, NAS, business to the RTP and RTCP, and signaling transmission business GTP - made C, GTP - U made, S1 - AP, involves the security and the Diameter of billing, IMS domain of SIP and SDP, and so on, of course, also lack of the TCP/IP,

You said this is almost the entire 3 g or LTE standard hollow agreement, not a year or two you don't know,

Then phone calls and text messages between use agreement, provide a keyword for your search: MAPVERSION 2

Mobile phone contact with the base station by Um interface, communication protocol for the physical layer in turn from bottom to top, the data link layer and layer 3, the third layer include MM, RR, CM! General mobile phone is based on GSM or CDMA, so can only use network communication operators,
Um interface is the air interface of GSM, Um interface communication protocol have 5 layers, from bottom to top in turn to the physical layer, MAC Mdium AccessControl) layer, LLC (Logical Link Control) layer, SNDC (Subnetwork DependantConvergence) layer and network layer,
