Description
The present invention relates to wireless communication technology field, and in particular to a kind of method of adjustment, system and the relevant device of voice auto-adaptive parameter.
Mobile bandwidth speech is in wireless access network equipment from global system for mobile communications (Global System for Mobile communication, abbreviation GSM)/CDMA access system (Code Division Multiple Access, abbreviation CDMA)/UMTS (Universal Mobile Telecommunications System, abbreviation UMTS) etc. to LTE evolution, wherein, once there are a variety of schemes for being used to solve LTE voices, the most commonly used but develop is the most quickly internet protocol-based IP multimedia subsystem, IMS (Internet Protocol Multimedia subsystem, abbreviation IMS) LTE network voice (Voice over LTE, abbreviation VoLTE), as full Internet protocol (Internet Protocol, abbreviation IP) epoch core net standard architecture.In the long run, VoLTE can bring three aspect values：One is lifting wireless frequency spectrum utilization rate, reduces network cost, the availability of frequency spectrum is more than 4 times of GSM；Two be lifting Consumer's Experience, and the high definition voice and video that VoLTE is introduced increases communication quality, and VoLTE calling duration significantly shortens；Three be VoLTE and the wireless of converged communication external member (Rich Communication Suite, abbreviation RCS) integrated can bring more abundant business.
Enhanced voice service (Enhanced Voice Service, abbreviation EVS) it is third generation cooperative partner program (the 3rd Generation Partnership Project, abbreviation 3GPP) the real-time Communication for Power audio coder ＆ decoder (codec) for aiming at packet switching network and designing.Compared with traditional audio coder ＆ decoder (codec), EVS can realize full HD voice call quality, can not only carry out natural voice communication, and entire audio spectrum can also reproduce music environment atmosphere.EVS speech coding parameters include speech encoding rate, sample rate, coding work pattern, bandwidth mode and RTP (Real Time Protocol, abbreviation RTP) load model etc., each coding parameter can be adjusted in the range of the option of offer, to obtain balance between voice quality and power system capacity, flexible deployment option is provided for Virtual network operator, for example, speech encoding rate supports 13 kinds of speech encoding rates, its speed range is from 5.9~128k changes, speech encoding rate can be adjusted continuously within the range, therefore when power system capacity increase, voice quality will not be deteriorated suddenly.
In existing EVS schemes, static configuration mode is used to EVS speech coding parameters, i.e., a kind of coding mode is set for system in advance, under this coding mode, speech coding parameters are all fixed, therefore power system capacity is also fixed.Coding mode once it is determined that, before setting and modifying to system, all-calls in system all use this coding mode.But, in actual applications, different application scene, different periods, the requirement to power system capacity or voice quality is inconsistent.For example when network is in higher load condition, often using relatively low code rate, lifting system capacity is carried out to sacrifice voice quality.If using the method for static configuration, it is difficult to pre-set out a kind of coding mode suitable for all scenes, and after the setup, also Mobile state adjustment can not be entered to coding mode according to the change of load or channel quality.
