What is a signaling? What is a signaling network?

[Guide]This article is for you letter of introduction and signaling network meaning, structure, signaling mode, signaling network division, performance indicators, coding methods, signaling three-layer structure. What is a signaling?

Signaling is a message passed between terminal and terminal, terminal, and network, which is designed to control circuits, establish, manage, and delete connections so that users can communicate properly through these connections.

What is signaling mode? What is included in the specific content?

Signaling means the rules and conventions that a signal is supposed to follow in the course of transmission. Including: The structure of signaling, signaling in the multi-segment routing, and signaling control mode.

What are the types of signaling?

The signaling network can be divided into two types: User signaling and inter-signaling according to its use.

User signaling acts on the switch between the user terminal equipment (such as a telephone) and the telephone exchange, which acts between two trunk-connected switches.

Inter-bureau signaling can also be divided into road signaling and co-signaling. Signaling is a signaling network attached to a computer network or telephone network, do not need to re-build a network. The co-signaling system requires a re-construction of a signaling network (mainly between the offices).

What is a signaling network?

Signaling network is a special data support network which transmits signaling to the public channel signaling system.

What constitutes a signaling network?

Signaling networks are generally composed of signaling points (SP), Signaling Junction (STP), and signaling links.

The signaling network can be divided into:

Signaling network by structure can be divided into: stepless signaling network, hierarchical signaling network.

Stepless Signaling Network: Signaling network is not introduced into the signaling point of contact, signaling between the use of direct-linked working mode. This way in the capacity and economy can not meet the requirements of the international and domestic signaling network, it is not widely used.

Grading Signaling Network: Signaling network containing signaling to the point of contact, it can be divided into two levels, three-level network. Most countries use the two-level network, when the two-level network can not meet the requirements, should adopt the three-level network.

What are the major types of signaling network performance indicators?

The availability index of signaling network;

Indicators of reliance on signaling networks;

The delay index of signaling network;

What are the signaling point encoding methods? What are the application scenarios?

Signaling Network International Code (CCITT) mode is 14bit, and the domestic point coding method uses 24bit.

What is the three level structure of signaling network?

Level three signaling network structure (HSTP, LSTP, SP), long-distance signaling network three, medium and large cities local network two, including the SP includes telephone Exchange Bureau, ISDN Exchange Bureau, Business Exchange point SSP, Business Control point SCP and so on.

Multilevel Signaling Network

The use of a few signaling networks depends on the following two factors: the number of signaling points the signaling network can hold and the capacity of the STP.

STP capacity can be represented by two parameters: STP can connect the maximum number of signaling chains, signaling processing capacity (the maximum number of message signaling units per second can be processed msu/s).

Among them, independent STP: The maximum number of signaling chain is not less than 256 links, signaling processing capacity is not less than 20000msu/s. Integrated STP: The maximum number of signaling chain is not less than 256 links, signaling processing capacity is not less than 10000msu/s.
