2 Signaling System #7 Process and Structure Course Number : TTH23 CLO : 2 Week : 5
3 CS and CCS CS: every information channel equally associated with signaling channel. The channel physically could be the same or different (separated in time or frequency) CCS: several information channels use common channel for signaling. Usually physically separated. Example of CCS is SS7 (Signaling System Number 7) n voice/data channel 1 2 voice/data channel signaling channel 1 2 Exchange n voice/data channel signaling channel Exchange B Exchange n 1 m << n Exchange B m m signaling channel
4 Signaling System 7 Elements (Signaling Point) (Signaling Transfer Point) SCP (Service Control Point) S (Service Switching Point) SEP (Signaling End Point) SL (Signaling Link) Link B Link C Link D Link E Link
5 Network Design Consideration 1. capacity Number of signaling links Signalling message transfer time Transmission capacity (bit rate) 2. Network performance Number of allowed Signaling delay 3. vailability & Reliability vailability: 1-level is worse (limited route) Reliability: 1-level is worse (limited route) link set signalling link link group link group Network Performance: 1-level is better (shorter delay)
6 One Level Structure Every is connected to at least 2 ll are connected in full mesh
7 Two Level Structure Every is connected to at least two lower level Every lower level is connected to at least two higher level ll higher level are connected in full mesh Higher level Lower level
8 Signaling: Case Study T&T Link Connects Function (ccess) ccess from LE/CO to Network Signaling B (Bridge) (same level) Connects 2 s in the same level C (Cross) (pair) lternate route when B fail D (different level) Connects 2 s in different level E Direct route F Direct route E E B D D D F C C B C D B B Signalling Point (=Switching Office)
9 Service Primitives request: issued by a service user to invoke a service element indication: issued by a service provider to advise that a service element has been invoked by the service user response: issued by the service user to complete a particular service element which invoked previously confirmation: issued by a service provider to complete a service element
10 Signaling Point Code Every has a unique identifier (ID), Signaling Point Code Sender s ID Originating Point Code Receiver s ID Destination Point Code
11 SS7 rchitecture 1. Signaling Data Link defines the physical, electrical and functional characteristics and the means to access it 2. Signaling Link defines the functions and procedures for and relating to the transfer of signaling messages over one individual signaling data link 3. Signaling Network defines those transport functions and procedures that are common to and independent of the operation of individual signaling links 4. User Part
12 Multiplexing TDM (Time Division Multiple ccess) GSM, GPRS, SS7 FDM (Frequency Division Multiple ccess) GSM, GPRS, WiFi CDM (Code Division Multiple ccess) Bluetooth, WiFi SDM (Space Division Multiple ccess) PDM (Power Division Multiple ccess)
