Description
Technical field
The present invention relates to utilize the media stream communication information statistical analysis of portable terminal device to improve mobile communication service quality, particularly relate to a kind of multimedia stream improving apparatus and method of portable terminal device.
Background technology
The three generations has been experienced in the development of mobile communication portable terminal device, the 1st generation (1G) at initial stage is a mode of utilizing analog voice level signal, the 2nd generation (2G) is the mode of utilizing by the word message level signal of digital processing, and the 3rd generation (3G) is then developed into the multi-communication mode that comprises voice level signal and word message level signal and image level signal.
For above-mentioned multimedia communication mode, owing to comprised voice level signal and literal level signal and image level signal, so want data quantity transmitted many, the bandwidth of distributing to channel needs wideer, channel data transmission speed or flow transmission speed need higher, have therefore distributed higher radio band.
Above-mentioned radio band is on characteristic, and the frequency band of distribution is high more, and it is big more influenced by barrier reflection, diffraction, refraction etc.In addition, portable terminal device need ensure mobility, owing to move and surrounding environment change etc. is former thereby disturb, causes wireless signal reception generation problem.
Particularly in the more area of skyscraper, building hinders the electric wave transmission, causes electric wave can not arrive the from cellar to rafter of business district well, so the shadow region (SHADOWAREA) of mobile communication service has taken place to use.In addition, business district, networking user and use the user many more for service provider, has often lost many chances.
In addition, the particular locality in the intensive business district of user, because the call volume that takes place or the traffic (TRAFFIC) may flash crowds, when the above-mentioned traffic had surpassed the channel capacity that corresponding area distributes, system can crash because of overload, causes service disruption.
Therefore, need a kind of technology of exploitation, make the bad statistics of service that the shadow region that takes place about a part of particular locality and traffic congestion etc. cause, detect, analyze, propose to improve the direction of the communication quality of corresponding area.
The media stream method of service of the portable terminal device of prior art is described with reference to the accompanying drawings.
Fig. 1 is the function constitution map of the portable terminal device mobile communication service deployment device of prior art, and Fig. 2 is the portable terminal device mobile communication service deployment method precedence diagram of prior art, and they all are used to illustrate prior art.
Below with reference to above-mentioned Fig. 1, the mobile communication service deployment device of the portable terminal device of prior art is described, mobile communication portable terminal device (UE:User Equipment) 10 carries out multimedia communication with not specific a plurality of people by calling out to be connected, above-mentioned portable terminal device 10 is in service area, and wireless connections have the base station (RAN:RADIO ACCESS NETWORK) 20 of base station controller (RNC:RADIO NETWORK CONTROLLER) and communicate.
Above-mentioned base station 20 is connected to mobile switching centre (MSC:MOBILE SWITCHING CENTER) 30, the wireless receiving signal is inserted above-mentioned mobile switching centre 30, the signal of 30 pairs of inputs of above-mentioned mobile switching centre (MSC) is analyzed, set up and call out (CALL), by above-mentioned call establishment, set up a path for the signal of communication transmission.So callee's portable terminal device 10 wireless connections of above-mentioned calling party's portable terminal device 10 and appointment communicate when moving.
The signal of 30 pairs of inputs of above-mentioned mobile switching centre is analyzed, if real-time call connection request signal, then handle by corresponding exchange, set up communication path, if non real-time transmission of messages call connection request signal, then insert the server (SERVER) 40 that message is managed, recorded and stored is carried out respective transmissions and is handled in assigned region.
Above-mentioned server 40 is transferred to word message, speech message, Multimedia Message the other side of appointment by Message Processing.
For the base station 20 that as above constitutes, fixed allocation the number of channel that can in the service area that forms, connect simultaneously, the portable terminal device 10 that surpasses the number of channel of said fixing distribution can't connect simultaneously, therefore, as mobile communication carrier, owing to service can't be provided, cause losing an opportunity.
In addition, for above-mentioned mobile switching centre 30, its capacity that can exchange processing simultaneously is defined, when surpassing above-mentioned capacity by each number that base station 20 connects and request call is handled, then can overload (LOAD), system thereby deadlock (DOWN) can't provide the mobile communication service.
Below with reference to Fig. 2, the portable terminal device mobile communication service deployment method of prior art is described.Mobile switching centre 30 judges after portable terminal device 10 connects whether utilize mobile communication service (step S10) in the media stream mode.In above-mentioned judgement (seeing step S10), when being when utilizing the service of media stream mobile communication, mobile switching centre 30 judges whether the traffic (TRAFFIC) is in the traffic (TRAFFIC) congestion state (step S20) of the scope that has surpassed accessible exchange processing capacity.
Judge in (seeing step S20) that in the above-mentioned traffic if assert traffic congestion, then above-mentioned mobile switching centre 30 so close (DOWN) system, stops utilization (step S60) owing to can't handle again; In above-mentioned judgement (step S20), if the traffic of mobile switching centre's 30 accessible degree, the intensity that then judges whether to be in the media stream wireless signal can not satisfy weak area or shadow region (SHADOW AREA) (the step S30) of communicating requirement.
In above-mentioned judgement (step S30), when portable terminal device 10 is positioned at the shadow region, can't realize wireless connections, so handle (step S50) as calling out connection failure; When leaving the shadow region, when being positioned at normal service area,, carry out media stream communication (step S40) by call connection processing.
Therefore, as above there are the following problems for the prior art of Gou Chenging, promptly, when portable terminal device 10 is positioned at the high density area of traffic congestion or shadow region that radio wave signal does not reach active strength, can't use the media stream communication service, operator be because of can't providing the media stream service and lose an opportunity or cause income to reduce, but also causes system employs degree of belief decline problem.
In addition, owing to can not distribute, dispose the mobile communication system resource, also exist and efficiently to share the problem that reaches the utilization system with optimum state.
