Specifically, the broadcast network may be a Radio Data System (RDS) network. The so-called RDS is a special radio broadcast developed by the British BBC Broadcasting Corporation. It uses the subcarrier in the FM radio transmission signal to send the station name, program type, program content and other information in digital form. These digital signals can be identified and processed by a tuner with RDS function. RDS broadcasting has the function of AF (Auto Frequency), that is, automatic frequency adjustment. When the signal is lower than a certain level, the AF function will automatically search for the current station When it finds another frequency with a better and stable signal than the original one, it will automatically jump to it (of course, the program is still the same). RDS radio also has a unique "communication information" function. If there is an emergency, the radio station will send a special signal to force the radio to play. As long as it enters the range covered by the RDS broadcast signal, communication devices such as mobile phones can receive the signal sent by RDS. For example, the RDS function provided by the existing mobile phone is used by many users to listen to the radio. Of course, the broadcast network can also be other networks with broadcast functions, such as satellite broadcast networks. It should be noted that, for the convenience of description, the embodiment of the present invention will use the RDS network as an example for illustration, but this does not constitute a The types of broadcast networks are limited, as long as the network has the function of broadcasting positioning service information, it belongs to the broadcast network referred to in the present invention

Specifically, the business processing is as shown in the above-mentioned agreement. For geographic information and positioning service auxiliary information, there are business processing methods such as initialization, update, addition, and deletion, and positioning service auxiliary information and geographic information can be selected. appear, or appear at the same time, which is determined by the specific circumstances. For example, in the process of using geographic information, it does not need to be updated and other business processing, then only positioning service auxiliary information can appear; otherwise, only geographic information can appear , if both of them require certain business processing, both of them can appear. Moreover, the positioning service information may also include control signaling for positioning service auxiliary information and/or geographic information, which is used to indicate initialization, update, addition, and deletion of the sent positioning service auxiliary information and/or geographic information. When there is no control signaling, the user can initialize, update, add, and delete the received positioning service assistance information and/or geographic information as required, for example, if the received positioning service assistance information and/or geographic information are of a higher version Based on the version of the existing positioning service auxiliary information and/or geographic information, use the received positioning service auxiliary information and/or geographic information to update the existing positioning service auxiliary information and/or geographic information, etc.; When there is a control signaling, the user equipment can automatically initialize, update, add, and delete the received positioning service assistance information and/or geographic information according to the control signaling, that is, if the control signaling indicates to update the existing positioning service assistance information information and/or geographic information, use the received positioning service assistance information and/or geographic information to update the existing positioning service assistance information and/or geographic information; if the control signaling indicates to delete the existing positioning service assistance information information and/or geographic information, use the received positioning service auxiliary information and/or geographic information to delete the existing positioning service auxiliary information and/or geographic information, etc., and the operations of initialization and addition are similar to this , which is no longer redundant here.

That is to say, the positioning service information may include positioning service auxiliary information, or geographic information, or positioning service auxiliary information and geographic information, or positioning service auxiliary information and control signaling, or geographic information and control signaling, or positioning service Auxiliary information and control signaling and geographic information and control signaling, etc. According to different positioning service information, the specific positioning service processing can be as follows:

When the positioning service information includes positioning service auxiliary information, the existing positioning service auxiliary information may be initialized or added or updated or deleted according to the positioning service auxiliary information;

When the positioning service information includes positioning service auxiliary information and control signaling, the existing positioning service auxiliary information may be initialized or added or updated or deleted according to the positioning service auxiliary information and control signaling;

When the positioning service information includes geographical information, the existing geographical information may be initialized or added or updated or deleted according to the geographical information;

When the positioning service information includes geographic information and control signaling, the existing geographic information may be initialized or added or updated or deleted according to the geographic information and control signaling;

When the positioning service information includes positioning service auxiliary information and geographic information, the existing positioning service auxiliary information and geographic information may be initialized or added or updated or deleted according to the positioning service auxiliary information and geographic information;

When the positioning service information includes positioning service auxiliary information, geographic information and control signaling, the existing positioning service auxiliary information and geographic information may be initialized or added according to the positioning service auxiliary information, geographic information and control signaling or update or delete.

Further, the communication device can also perform the following steps:

The communication device receives geographic location information;

The communication device comprehensively analyzes the geographic location information and the positioning service information, such as positioning service auxiliary information and/or geographic information, to obtain geographic reference information, so as to provide users with more valuable information.

The geographical position information here may be the geographical position information received through the global positioning satellite, or the geographical position information corresponding to the cell information obtained through the mobile communication network or the mobile terminal, or the geographical position information obtained through the mobile communication network server .

For example, geographic location information can be obtained by the communication device itself using the first type of positioning technology based on the GSM network or the second type of positioning technology based on the CDMA network mentioned above, or a new technology that combines these technologies organically. The longitude and latitude of the location or the spatial location data information of the location, for example, more GPS positioning technology or CELL-ID technology is now used. For example, when a user travels to a certain place and receives positioning service information sent by the server of the wireless data broadcasting system, the user equipment performs protocol analysis to obtain positioning service auxiliary information and geographical information. At this time, the positioning service auxiliary information indicates that the user should A certain place in the region is under traffic control, and because the geographical information is updated compared with the geographical information stored and used by the user before, the user device updates the geographical information, and then judges the traffic according to the received geographical location information, that is, the longitude and latitude Will the location of the control affect your arrival at the destination, should you change your original route, should you wait for the end of the control, etc.? In this way, the location-related information sent by the server of the wireless data broadcasting system can be organically combined with the geographic location information, thereby providing users with more valuable geographic reference information.

It should be noted that as for which positioning service information the communication device receives, or whether it needs to obtain geographic reference information, it can be preset according to the individual needs of the user, that is, the user can perform positioning in various types of services provided by the operator. Select and reserve, or set the receiving configuration of the communication device, etc., to determine whether the user's communication device can receive positioning service information, which positioning service information can be received, and whether to obtain geographic reference information, etc.

Further, before or at the same time as step 101, it also includes:

The communication device sends an authentication request message to the positioning server, and the authentication request message may be sent by means of a short message or a hypertext transfer protocol (HTTP, HyperText Transfer Protocol) message;

The communication device receives a result message from the positioning server indicating whether the authentication is passed, that is, if the authentication is passed, the communication device receives a result message from the positioning server indicating that the authentication is passed, and if the authentication fails, the communication device receives the result message from the positioning server. The sent result message indicating that the authentication is not passed.

The above two steps are completed through the mobile communication system server as an intermediary. Because the wireless data broadcasting network used by the server of the wireless data broadcasting system is a network that can only send data downlink and cannot send data uplink. Therefore, the authentication service must be completed with the help of the mobile communication system server in the prior art. The authentication service can be used for the positioning server to perform statistics on users who use the wireless data broadcasting system for positioning, or because it provides paid wireless data broadcasting The system locates the service and authenticates the user's right to use it. For example, it can be set that the user can receive the positioning service information sent through the broadcast network only when the user receives the result message indicating that the authentication has passed, that is, only users who have opened this service can Receive positioning service information sent through the broadcast network.

Further, when the location service information in the step of receiving the location service information sent through the broadcast network is encrypted, the location service information for decrypting the encryption may also be received while receiving the message indicating the result of passing the authentication. The key of the information, for example, can receive the key for the authorized user to decrypt the received encrypted positioning service information. Wherein, the key may be carried in the result message indicating that the authentication has been passed, or it may be a separate piece of information. Of course, some public positioning service auxiliary information or geographical information may be sent to the user without encryption. It is even sent to users forcibly, such as some emergency information, you can use the forced playback function of RDS itself to prompt the user, so that even if the user is in the state of turning off the communication device, he can still receive such emergency information. information for decision-making.

The process of using the key may be: the communication device uses the key to decrypt the encrypted positioning service information to obtain positioning service auxiliary information and/or geographical information.

It can be seen from the first embodiment of the positioning service processing method that communication devices such as mobile phones can use the data broadcasting function of a broadcast network such as a wireless data broadcasting system to receive positioning service information such as positioning service auxiliary information and geographical information, and can update the positioning service auxiliary information Business processing with geographical information, and because the wireless data broadcasting system technology can realize the channel data of roaming wireless data broadcasting in its public channel, so that communication equipment can timely and correctly obtain the channel issued by the roaming wireless data broadcasting system Finally, geographical information and positioning service auxiliary information of the roaming area can be obtained in time. In this way, the mobile communication resources that realize the same function in the prior art can be saved, and compared with the prior art, the solution provided by the embodiment of the present invention can better meet the user's individual requirements, because the positioning service in the prior art Auxiliary information and geographic information are generally public information, that is, the content received by multiple people is the same, while the business information in the embodiment of the present invention can be reserved according to the needs of users, that is, it can be provided to users Better location services.
