A kind of integration switch system and integrated exchange method that merges IMS territory and CS field technique

Technical field

The present invention relates to communication technical field, particularly a kind of integration switch system that merges IMS territory and CS field technique andIntegrated exchange method.

Background technology

In recent years, IMS (IPMultimediaSubsystem, IP multimedia system) deployment scope progressively expanded, moreCome more operators and equipment vendor and start to accept IMS. But for some large-scale operators, make the overall arrangement for IMSAlso face some problems: first, existing network size is very huge, be difficult at short notice network be carried out to complete upgrading;Secondly, be limited to current PS territory (PacketSwitch, packet switch) access capability, be difficult to the territory (Circuit by whole CSSwitch, circuit switching) user proceeds to packet domain; In addition, complete upgrading will inevitably be eliminated a large amount of existing network equipment, and this is not yetBe beneficial to investment protection. For dedicated network user or industry user, on the CS territory network foundation of having built up, introduce simultaneouslyIMS network, reaches the maximum utilization of equipment and technology by the fusion of CS territory and IMS territory network, be also that one must becomeGesture.

IMS based on IP technology has broken the bottleneck in traditional circuit domain ability, IMS with its distinctive opening, flexibilityDevelop by leaps and bounds, its trend that becomes core network of future generation is extensively admitted by industry. But a networkEvolution needs considerable time. Therefore within the regular period from now on, CS territory also will exist, and also will have suitable onePoint user is accessed by CS territory, namely over a period to come IMS territory and CS territory incite somebody to action and deposit. At IMS and CS and depositIn period, the user that operator can select to allow IMS territory and CS territory be respectively in territory separately provides business, and two territories respectivelyManage. Therefore, how to handle the throw the net relation of network of the old and new two well, making it bring into play maximum ability just becomes one urgentlyProblem to be solved.

There are a lot of significantly shortcomings in this mode: concurrent maintenance two network of throwing the net will certainly increase O&M cost; Need to ensure IMSThe uniformity of territory and CS territory business needs extra work; IMS and CS business providing capability are not reciprocity, and some business can onlyOpen in IMS territory and CS territory user cannot use these business.

In special industry user, also there is Similar Problems, for example military mobile network communication system or emergent mobile network communicationHow in IMS and CS territory also in system, how the miniaturization network equipment of high integration supports IMS and two territories of CS,Unified business is provided in the network of depositing, user is experienced unanimously, to reach the network integration and integrated services, this is all needThe problem solving.

For these problems, 3GPP (The3rdGenerationPartnershipProject, third generation technical specification) proposesA solution be IMS centralized traffic control (ICS, IMSCentralizedService). The core concept of ICS isComplete all Service controls by IMS, by gateway by CS domain signaling be converted to SIP (SessionInitiationProtocol,Session initiation Protocol) signaling, make CS territory become a kind of access way of IMS. ICS not only can give full play to existing network CSThe surplus capacity in territory, and made up the deficiency in the business providing capability of CS territory. Under ICS pattern, only complete by IMS territoryBecome Service control, therefore do not need two service networks to safeguard, greatly reduce O&M cost, and can ensure CSUser and IMS user's business uniformity.

3GPP starts ICS to carry out standardization from Rel8 version, has proposed respectively two kinds of different ICS implementations, butBe that this two schemes all exists larger obstacle in specific implementation process, IMS is fast-developing at present in addition, realizes ICSDemand more and more stronger. Simultaneously because ICS framework is the frame of reference putting forward on existing civilian network foundation, notConsider special industry user's demand: device miniaturization, system be removable, it is efficient and convenient to open. Therefore be starved ofThe integration switch system scheme in a kind of enforceable fusion IMS and CS territory is proposed on the basis of 3GPP specification.

The proposition of ICS provides a feasible road to the evolution of IMS network for existing CS core net. 3GPP has proposedTwo kinds of ICS schemes have also been carried out standardization to it, are respectively ICS scheme and network ICS scheme based on terminal.But the ICS scheme based on terminal too depends on UE capability, require user to upgrading or upgrade existing terminal, because ofIt is very large that this promotes difficulty. Network ICS scheme is placed on network side by ICS what's new and realizes, and subscriber equipment is not doneAny requirement, is therefore easier to promote, but because this scheme need to be carried out complete upgrading to VMSS all in network,The network element relating to is too much, needs a large amount of costs to drop into and the quite long engineering time. Existing these two kinds of ICS schemes are at toolDifficulty in body implementation process is all very large.
