Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and device of adaptive multi-rate adjustment.
Background technology
Second generation mobile communication system (2nd Genaration, abbreviate 2G as) global mobile communication (Global system for Mobile Communication, abbreviating GSM as) network developed for many years in China, there is a good national GSM network that covers in China Mobile, the construction of current GSM network is quite ripe, has good spreadability and stability, and the voice service of high-quality can be provided, still can be good speech business bearer network future, and this is very valuable resource.On the other hand, along with 3-G (Generation Three mobile communication system) (3rd Genaration, abbreviate 3G as) the continuous maturation of technology, the quickening of commercial process, and in the progressively promotion and application in the whole world, 3G network is with its higher availability of frequency spectrum and can provide the business of abundanter personalization to obtain approval widely.With respect to the 2G system, 3G network has greatly improved in the support to the data business, and for mobile Web access, audio stream, video flowing, and the support of IP multimedia call etc. is all more perfect.So 2G and 3G coexistence of systems will be a kind of long-standing situations.
A standard interface Iur-g between 2G and 3G wireless access system is arranged in third generation partner program (3rd Generation Partnership Project the abbreviates 3GPP as) international standard protocol, and this interface is not supported the user service data transmission of Information.Under the background of current 2G and 3G coexistence of systems, in particularly being switched to the voice of 2G by 3G, by (the Iur Interface between RNC and GSM of the logic interfacing between RNC and the GSM, abbreviate Iur-g as) interface transmission user business datum, it is very necessary to improve between handover success rate assurance system load balancing.
