Embodiment
The present invention is in order to solve the drawback that conventional solution exists, further set forth a kind of method of the present invention by following specific embodiment with mobile terminal system and a kind of expanding reception range of mobile phone television service of mobile phone TV services function, below embodiment is described in detail, but not as a limitation of the invention.
The mobile communication system that has the mobile multimedia receiving system of broadcast system and telecommunications standard on the terminal of the present invention simultaneously is double mode.The user can obtain the mobile phone TV services of radio network by mobile communication system when needed, utilizes the network coverage, the roaming advantage of mobile communications network, reaches the purpose of expanding reception range of mobile phone television service.
In dual-mode communication systems, as shown in Figure 1, be network system schematic diagram in the embodiment of the invention.
At network side, by mobile TV forwarding server 10, receive the mobile phone TV services that mobile TV source device 11 sends, as the multimedia service source of mobile communications network, accessing mobile communication network 12, and obtain mobile phone TV services from this network 12 by portable terminal 14; In view of the characteristics of mobile phone TV services, mobile TV forwarding server 10 operates mainly in live-mode; Simultaneously, can also obtain mobile phone TV services by portable terminal 14 from this network 13 by inserting mobile media broadcasting network 13.
Portable terminal 14 is distinguished a little less than mobile broadcast television blind area or signal, receive the mobile TV broadcasted content and watch by mobile communications network 12, in this way, except the coverage that can expand spot broadcasting, can realize that also the strange land broadcasted content receives in the other places.
Mobile terminal system with cell phone television business function is divided by function, mainly is made of two subsystems: communication subsystem and mobile phone TV services subsystem.
Communication subsystem is mainly by comprising: several sections such as radio-frequency module, SIM card module, memory module, keyboard, base band and application processor are formed, and are used to finish the basic communication service of terminal; And the mobile phone TV services subsystem is accepted the management and the allotment of base band and application processor, finishes mobile phone TV services of the present invention, the following specifically describes the formation of mobile phone TV services subsystem.
As shown in Figure 2, mobile phone TV services subsystem structure schematic diagram for terminal in the embodiment of the invention, front-end module 20 with mobile broadcast front end 200 and mobile communication front end 201 double-standards, be subjected to described control module 22 allotments, provide the accesses network inlet by described Subscriber Interface Module SIM 21, the Streaming Media of setting up terminal to network side mobile TV source device or mobile TV forwarding server respectively connects, and receiving demodulation is based on the mobile phone TV services of digital broadcast network or mobile communications network; Decoding playing module 23, controlled module 22 adjustmenting managements are used for the business datum that is received that front-end module 20 transmits is decoded, represented; Subscriber Interface Module SIM 21, by each professional accesses network inlet of record in the inlet control table 210, controlled module 22 adjustmenting managements provide uses, operate the interface of corresponding service to the user; Control module 22 (allocated by above-mentioned base band and application processor), control communication and operation between described each module, be used for obtaining by described mobile broadcast 200 or mobile communication front-end module 201 in real time the signal strength signal intensity of corresponding network, and, enable corresponding front-end module and obtain mobile phone TV services according to this signal strength signal intensity.
For certain mobile phone TV services, Subscriber Interface Module SIM 21 presents a unified interface to the cellphone subscriber, and the user is by these interface accessing mobile phone TV services; This interface is to enter the mouth by the Operational Visit of record in the inlet control table 210 to implement to the visit of business;
User applies after obtaining this function of mobile phone TV services of radio network by mobile communication system, promptly in inlet control table 210 at the concrete business of user applies, increase an Operational Visit inlet, this Operational Visit inlet points in the mobile communications network, the access to netwoks inlet of mobile phone TV services can be URL (the Uniform Resource Locator unified resource location) address of a RTSP (Real Time Streaming Protocol real-time streaming protocol) mode on the visit mobile TV forwarding server.
When the user in the strong zone of digital broadcast network signal, when using mobile phone TV services, control module is directly enabled the business that the mobile broadcast front-end module comes the receiving digital broadcast network according to the intensity of network signal; When the residing zone of user, when the digital broadcast network signal is very weak, obtain mobile phone TV services by mobile communication system.
As shown in Figure 3, be method flow diagram in the embodiment of the invention, may further comprise the steps:
Step 300, beginning extended mobile phone television services flow process;
Step 301 detects the signal strength signal intensity of mobile broadcast network in real time, and this signal strength signal intensity is lower than threshold value, execution in step 303; Otherwise, execution in step 302;
Step 302 equals threshold value when the signal strength signal intensity of mobile broadcast network is higher than, and then uses mobile broadcast network, continues to obtain mobile phone TV services;
Step 303 is enabled mobile communications network and is obtained business, and waits for that the user confirms; If the user confirms to start mobile communications network, then execution in step 305; If the user refuses to start mobile communications network, then execution in step 304;
Step 304 finishes the visit of these mobile phone TV services;
Step 305 is visited the inlet control table in the described Subscriber Interface Module SIM, obtains in the mobile communications network accesses network inlet of these mobile phone TV services;
Step 306, startup is communicated by letter with mobile communication network side, and the Streaming Media of setting up by terminal to network side TV forwarding server connects;
Step 307, from the connection of described foundation, terminal receives the mobile phone TV services data;
Step 308 is to the mobile phone TV services data of the receiving broadcast of decoding.
In addition, this method can when the network signal of mobile broadcast network is very weak, be confirmed process without the user by being provided with or the default configuration mode, directly switches, and receives mobile phone TV services by mobile communication system;
And after step 308 executes, when terminal has been carried out mobile phone TV services under mobile communications network, still need to detect in real time the signal strength signal intensity of mobile broadcast network, if signal strength signal intensity is higher than threshold value, signal takes a turn for the better, and should switch the moving radio network of travelling backwards, to guarantee better quality of service.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
