Description
Technical field
The present invention relates to the method for a kind of definite ground digital TV network, relate in particular to a kind of method of utilizing information of mobile communication base station to determine the ground digital TV network.
Background technology
Digital Television is divided into three kinds, be respectively terrestrial DTV, cable digital TV and satellite digital TV, wherein, terrestrial DTV can carry out the digital television signal issue and receive under wireless and relative-movement state, and it is therefore characteristics and obtained using widely also.
China has issued the national ground digital television channels transmission standard GB20600-2006 with independent intellectual property right in August, 2006.So far, Chinese ground standard becomes the 4th terrestrial DTV standard in the world.
Through development in a few years, terrestrial DTV has carried out the network coverage in national, provincial and important city and has carried out relevant business.Yet the scope of the terrestrial DTV network coverage is limited, and its coverage can be in tens kilometers, so can have following covering problem in the development of the terrestrial DTV network coverage:
1, owing to be subjected to the influence of landform, some regional network coverage meeting is using large tracts of land to cover the mode that covers by other frequencies in the blind area on the basis;
2, adjacent two administrative regions or more wide zone be not owing to reasons such as frequency planning, distance, content construction use same frequency to carry out the construction of Single Frequency Network, thereby occur using a plurality of frequencies to carry out the situation that ground covers.
The characteristics of above-mentioned covering can occur in the terrestrial DTV network coverage afterwards frequently.For the terminal receiving equipment, owing to can move reception, the problem of another one network's coverage area will appear carrying out the transition to from a network's coverage area.The terminal receiving equipment from receive one the network video, data, services then receive video, data, services in the another one network, with continuous be this process that the user provides the terrestrial DTV service, be called " roaming ".
Because the ground digital television channels transmission network is the network of a broadcasting property, promptly transfer of data is a single direction, aloft transmits to the terminal receiving equipment from fixing television transmitting station in TV broadcast applications.Simultaneously, the characteristics of terrestrial DTV are the digital television signals that receiving equipment locked and received a simulation frequency at one time.Based on such situation, the terrestrial DTV terminal if from a network coverage under the situation that the another one network coverage is moved, normally adopt and search for manually/switch or the mode of passive roaming solves.
The mode of passive roaming mainly is a situation of knowing the terrestrial DTV network coverage in ground digital television signal or other approach as the mode that is stored in terminal in advance, which frequency the network coverage as an area and adjoining area has used separately, and service of which professional drawn game body or the like is provided in the frequency.
Digital television signal occur unstable, the error rate increases, under the situation of signal strength weakening, reception of souning out and present network cover the frequency of the use of exterior domain adjacent areas, if there are parameters such as signal and signal quality, intensity to meet the requirements, switch after then judging, to reach the purpose of roaming by imposing a condition.The passive type roaming has following shortcoming:
1, roaming is passive.Promptly the measure just taked under the bad situation occurred at network, this moment, the user obviously experienced the decline of service quality, mosaic occurred as video, and sound is discontinuous or data, services occurs pausing, loses or situation such as prolongation.
2, roaming might be unsuccessful.Because ground digital TV receiving terminal is to judge by some phenomenons, be problems such as network quality, judgement to the position of terminal self also can go wrong, and promptly has the situation that may not go out a network's coverage area and sound out, service impacting continuity and quality; Also having a kind of may be because the mistake of judging on opportunity, thus roaming of evening too early or excessively, and this angle from the user also is unsuccessful.
This shows that terminal be because can't accurately know the multiple frequency network, MFN information of current frequency overlay area periphery, thus make when terminal is in current frequency overlay area peripheral position can not be accurately and timely the switching frequency, and then influenced the service quality of terminal.
Summary of the invention
The object of the present invention is to provide a kind of method of determining the ground digital TV network based on information of mobile communication base station, make terminal accurately and timely switch frequency at current frequency overlay area peripheral position, thereby guarantee the service quality of terminal according to this terrestrial DTV network information of determining of determining.
