Abstract
The invention discloses a system, a method and equipment for controlling network access, and aims to solve the problem that the service quality of a mobile network can be improved only by increasing network construction cost. In the invention, service signal requiring quality assurance in a first call is transmitted by first access control equipment; and other service signals in the call except the service signal requiring the quality assurance are transmitted by second access control equipment. By the invention, different service signals in the call can be transmitted by different access control equipment, so that the service signal requiring the quality assurance can be transmitted by backhauling resources with quality assurance, other service signals without requiring the quality assurance can be transmitted by wideband backhauling resources in low cost; therefore, under the condition of not increasing network construction cost, the transmission quality of the service signal requiring the quality assurance is ensured.
Description
Technical field
The present invention relates to the communications field, relate in particular to system, the method and apparatus of network insertion control.
Background technology
Along with the continuous evolution of mobile network, broadband trend becomes clear day by day, single user rate improves constantly, from before 144～360Kbps bring up to～144Mbps, improve nearly 400～1000 times, possessed the technical capability of broadband access from HSPA (High speed packet access) beginning mobile network.End-to-end E2E in this process (End to End) One Way Delay also progressively is reduced to 20ms from 150ms
Be the broadband trend of reply mobile network, mobile network architecture constantly develops to flattening, progressively evolve to the two-tier system of HSPA+/SAE (System architecture evolution) from four layer architectures of 3GPP R99, gateway GW (Gateway) position finally also will constantly move down.
With reference to figure 1, in each stage of network development, a technology is arranged less than becoming, promptly a terminal only can be linked into core net by a serving BS in an area of coverage, and various types of business that terminal is used are also all multiplexing on same access link.
In current mobile network based on voice, the base station is linked into RNC (Radio NetworkController, radio network controller) or core net by transmission, and miscellaneous service can be provided simultaneously.But follow wireless technology to improve constantly and the mobile broadband application and development, more and more higher to the transmission capacity requirement of base station, the base station area coverage also can constantly be dwindled, and the density of deployment also can increase considerably.
The inventor finds that except that the base station that transfer resource is arranged of original deployment, other transmission backhaul resources problems that increase the base station newly are on the rise in realizing process of the present invention.Described transmission backhaul resources is meant transmission of traffic signal (as service signals such as voice, data) transmission channel between access control equipments such as base station and the core control equipment.If these base stations also were linked into core net with the base station is the same originally by transmission, huge cost expense will be produced, and may cause can't finishing deployment because of building or other barriers, so the mobile broadband network of setting up also will be competitive because of cost reason difficulty. at all
Reduce the cost expense, also can newly the local area network (LAN) of base station by disposing will be increased nearby, ADSL (Asymmetric Digital Subscriber Loop/Line, ADSL (Asymmetric Digital Subscriber Line)) data Access Network backhaul such as network is linked into core net, but because these networks are based on the fixed data service construction is provided, there is not service quality QoS (Quality of Service) assurance ability between net and the net, network failure is handled also relatively difficulty, this just causes, and the user's voice business service can't be guaranteed under new base station covers, particularly as the speech business of this class of urgent call, if there are not good assurance means to bring application hidden danger to the user, such network also is difficult to meet the demands.
Therefore, under prior art, follow the development of mobile broadband,, then do not increase the requirement that is difficult to satisfy the high-quality speech service under the situation of network cost if call still only continues by an access control equipment.
Summary of the invention
The embodiment of the invention provides a kind of system, method and apparatus of network insertion control, and service signals different in the call by different access control equipment transmission, is improved the transmission quality of service signal under the situation that does not increase network cost.
The embodiment of the invention discloses a kind of network access control system, comprising:
First access control equipment, described first access control equipment possesses the transmission backhaul resources of quality assurance, is used for transmission primaries and calls out the service signal that requires quality assurance;
Second access control equipment is used for transmitting described calling and requires service signal outside the service quality assuranced signal.
