The indication is a geographic information data packet, the length of the data packet is 100 bytes, an intelligent operation is required to be carried out, and binary data of 90 bytes are carried behind the data packet.
In particular, the broadcast network may be a Radio Data System (RDS) network, the RDS being a special Radio broadcast developed by BBC broadcasters in the united kingdom. It utilizes subcarrier to send out the station name, program type, program content and other information in digital form in FM broadcast transmitting signal. The digital signals can be identified by a tuner with RDS function and response processing is carried out, the RDS broadcast has AF (auto frequency) function, namely automatic frequency adjustment, when the signal is lower than a certain level, the AF function can automatically search other transmitting frequency strings of the current station, and when another signal with a frequency which is better and more stable than the original frequency is found, the broadcasting station can automatically jump to the past (of course, the program is the same). RDS broadcast also has the function of 'exchanging information', if there is an emergency, the radio station will send special signal to make the radio play forcibly. As long as the communication device enters the range covered by the RDS broadcast signal, the communication device, such as a mobile phone, can receive the signal transmitted by the RDS, such as the RDS function provided by the existing mobile phone, and is used by many users for listening to the broadcast. Of course, the broadcast network may also be other networks having a broadcast function, such as a satellite broadcast network, and it should be noted that for convenience of description, the RDS network will be taken as an example in the embodiment of the present invention for illustration, but this does not limit the kind of the broadcast network used, and any network having a function of broadcasting positioning service information belongs to the broadcast network referred to in the present invention
Specifically, the service processing is as shown in the above protocol, and there may be service processing modes such as initialization, update, addition, deletion, and the like for the geographic information and the positioning service auxiliary information, and the positioning service auxiliary information and the geographic information may appear alternatively or simultaneously, which is determined by specific circumstances, for example, in the using process of the geographic information, the service processing such as update is not required, and only the positioning service auxiliary information may appear, or conversely, only the geographic information may appear, and if both of them require certain service processing, both of them may appear. In addition, the positioning service information may further include a control signaling for the positioning service assistance information and/or the geographic information, which is used to indicate initialization, update, addition, or deletion of the sent positioning service assistance information and/or the geographic information. When there is no control signaling, the user may initialize, update, add, delete the received positioning service assistance information and/or geographic information as needed, for example, if the version of the received positioning service assistance information and/or geographic information is higher than that of the existing positioning service assistance information and/or geographic information, update the existing positioning service assistance information and/or geographic information with the received positioning service assistance information and/or geographic information, and so on; when a control signaling exists, the user equipment can automatically initialize, update, add and delete the received positioning service auxiliary information and/or geographic information according to the control signaling, namely, if the control signaling indicates to update the existing positioning service auxiliary information and/or geographic information, the received positioning service auxiliary information and/or geographic information is utilized to update the existing positioning service auxiliary information and/or geographic information; if the control signaling indicates to delete the existing positioning service assistance information and/or geographical information, the received positioning service assistance information and/or geographical information is used to delete the existing positioning service assistance information and/or geographical information, and so on, and similarly, the initialization and addition operations are not burdensome here.
That is, the positioning service information may include positioning service assistance information, or geographic information, or positioning service assistance information and control signaling, or geographic information and control signaling, and the like. According to different positioning service information, the positioning service processing specifically may be as follows:
when the positioning service information includes positioning service auxiliary information, initializing, adding, updating or deleting the existing positioning service auxiliary information according to the positioning service auxiliary information;
when the positioning service information includes positioning service auxiliary information and a control signaling, initializing, adding, updating or deleting the existing positioning service auxiliary information according to the positioning service auxiliary information and the control signaling;
when the positioning service information comprises geographic information, initializing, adding, updating or deleting the existing geographic information according to the geographic information;
when the positioning service information comprises geographic information and control signaling, initializing, adding, updating or deleting the existing geographic information according to the geographic information and the control signaling;
when the positioning service information includes positioning service auxiliary information and geographic information, initializing, adding, updating or deleting the existing positioning service auxiliary information and geographic information according to the positioning service auxiliary information and the geographic information;
when the positioning service information includes the positioning service auxiliary information, the geographic information and the control signaling, the existing positioning service auxiliary information and the geographic information may be initialized, added, updated or deleted according to the positioning service auxiliary information, the geographic information and the control signaling.
Further, the communication device may further perform the steps of:
the communication equipment receives geographical position information;
the communication equipment comprehensively analyzes the geographic position 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 more valuable information for users.
The geographical location information may be geographical location information received through a global positioning satellite, or geographical location information corresponding to cell information acquired through a mobile communication network or a mobile terminal, or geographical location information acquired through a mobile communication network server.
For example, the geographical location information may be longitude and latitude of the communication device itself or spatial location data information of the communication device itself, which is obtained by using the first type of GSM network-based positioning technology or the second type of CDMA network-based positioning technology mentioned above, or by using a new technology that organically combines these technologies, such as the GPS positioning technology or the CELL-ID technology that is more adopted nowadays. For example, when the user travels to a certain place, the positioning service information sent by the wireless data broadcasting system server is received, the user equipment performs protocol analysis to obtain the positioning service auxiliary information and the geographic information, at this time, the positioning service auxiliary information indicates that the user is performing traffic control in the certain place in the area, and the user equipment updates the geographic information because the geographic information has an update part compared with the geographic information used by the user, and then judges whether the place performing traffic control affects the arrival destination of the user according to the received geographic position information, namely, longitude and latitude, whether the original route should be changed, whether the end of the control should be waited, and the like. Therefore, the information related to positioning and the geographical position information transmitted by the wireless data broadcasting system server can be organically combined, thereby providing more valuable geographical reference information for users.
It should be noted that what kind of positioning service information is received by the communication device, or whether geographical reference information needs to be obtained, may be preset according to the personalized requirements of the user, that is, the user may select and preset from multiple service types provided by an operator, or set the receiving configuration of the communication device, and so on, to determine whether the communication device of the user may receive the positioning service information, which kind of positioning service information may be received, and whether geographical reference information needs to be obtained, and so on.
Further, before or at the same time of step 101, the method further comprises:
the communication equipment sends an authentication request message to the positioning server, wherein the authentication request message can be sent in a short message mode or a HyperText Transfer Protocol (HTTP) message mode;
the communication equipment receives a result message which is sent by the positioning server and indicates whether the message passes the authentication, namely if the authentication passes, the communication equipment receives the result message which is sent by the positioning server and indicates that the message passes the authentication, and if the authentication does not pass, the communication equipment receives the result message which is sent by the positioning server and indicates that the message does not pass the authentication.
Both steps are performed by the intermediary of the mobile communication system server. The wireless data broadcasting network used by the wireless data broadcasting system server is a network which can only transmit data in a downlink and cannot transmit data in an uplink. Therefore, the authentication service must be completed by the mobile communication system server in the prior art, the authentication service can be used for the positioning server to count the users who use the wireless data broadcasting system for positioning, and can also be used for the user right authentication because the paid wireless data broadcasting system positioning service is provided, for example, when the user receives the result message indicating passing the authentication, the positioning service information sent by the broadcasting network can be received, namely, only the user who opens the service can receive the positioning service information sent by the broadcasting network.
Further, when the positioning service information in the step of receiving the positioning service information transmitted through the broadcast network is encrypted, a key for decrypting the encrypted positioning service information may be received at the same time as the step of receiving the result message indicating passing of the authentication, for example, a key for decrypting the received encrypted positioning service information by an authorized user may be received. The key may be carried in the result message indicating that the authentication is passed, or may be a single piece of information, and certainly some public positioning service auxiliary information or geographic information may be sent to the user without being encrypted, or even forcibly sent to the user for use, for example, some emergency information, and the user may be prompted by using the forced play function of RDS itself, so that even if the user is in a state of closing the communication device, the information about such an emergency can be received, so as to make a decision.
The key usage process may be: and the communication equipment decrypts the encrypted positioning service information by using the key to obtain the positioning service auxiliary information and/or the geographic information.
As can be known from the first embodiment of the positioning service processing method, a communication device such as a mobile phone can receive positioning service information such as positioning service auxiliary information and geographic information by using a data broadcasting function of a broadcasting network such as a wireless data broadcasting system, and can perform service processing on the positioning service auxiliary information and the geographic information, and because the wireless data broadcasting system technology can transmit channel data of wireless data broadcasting in a roaming place in a public channel thereof, the communication device can timely and correctly obtain channel data sent by the wireless data broadcasting system in the roaming place, and finally can timely obtain the geographic information and the positioning service auxiliary information in the roaming place. Therefore, mobile communication resources for realizing the same function in the prior art can be saved, and compared with the prior art, the scheme provided by the embodiment of the invention can better meet the personalized requirements of users, because the positioning service auxiliary information and the geographic information in the prior art are generally public information, namely, the contents received by multiple persons are the same, and the service-defined information in the embodiment of the invention can be subscribed according to the needs of the users, namely, better positioning service can be provided for the users.
Second embodiment of a method for processing a location service
As shown in fig. 2, the step of the second embodiment of the location service auxiliary processing includes:
step 201: the positioning server packages the related information of the positioning service to obtain the positioning service information;
the positioning service related information refers to information related to positioning services, such as longitude and latitude information, and/or traffic flow information, and/or traffic signal information, and/or traffic control information, and/or regional public security information and the like; the positioning service information refers to information formed by encapsulating positioning service related information according to a certain format, and may be positioning service auxiliary information, or geographic information, or positioning service auxiliary information and control signaling, or geographic information and control signaling, or positioning service auxiliary information and control signaling, geographic information and control signaling, and the like.
Step 202: and the positioning server sends the positioning service information through a broadcast network.
In step 202, the positioning server may send the positioning service information through a wireless data broadcasting system network or a satellite broadcasting network, but is not limited to these two ways. The positioning service information may be positioning service assistance information and/or geographical information.
Further, the above steps (before or after or simultaneously with the above steps) may further include:
the positioning server receives an authentication request message;
the positioning server carries out authentication analysis on the user sending the authentication request message to obtain a result message of whether the user passes the authentication, namely if the user passes the authentication, the positioning server obtains a result message of passing the authentication, and if the user does not pass the authentication, the positioning server obtains a result message of failing the authentication;
the positioning server sends a result message indicating whether the authentication is passed, i.e. sends a result message indicating that the authentication is passed or sends a result message indicating that the authentication is not passed.
Further, step 201 may specifically include: and the positioning server encrypts and encapsulates the positioning service related information to obtain encrypted positioning service information. Step 202 may specifically include: the location server may transmit the encrypted location service information through a broadcast network.
Further, the location server may also transmit a key for decrypting the encrypted location service information through the mobile communication network. The key may be sent in a result message indicating that the authentication is passed. The authentication in combination with the key may provide the user with a location service that is charged.
For the description of the positioning service information, the authentication, the key, and the like, reference may be made to embodiment one, which is not redundant here.
As can be seen from the second embodiment of the positioning service processing method, the positioning server is responsible for performing protocol encapsulation on the collected related positioning service auxiliary information and/or geographic information by using a specific protocol (see the protocol example in the first embodiment of the positioning service processing method) to obtain positioning service information, and sending the positioning service information to the communication device, so that mobile communication resources for realizing the same function in the prior art can be saved, the communication consumption burden of a user is reduced, and better positioning service is provided for the user.
