Detailed ways

In the prior art, the terminal positioning operation is carried out during each call, and the CRBT is determined according to the position of the terminal, which brings great pressure to the CRBT service server; The position information after the terminal position changes determines and saves the color ring data corresponding to the changed position information; in this way, when the terminal is used as the called terminal during the calling process, the stored color ring data corresponding to the terminal is directly played. In this way, it is not necessary to perform the operation of determining the color ring tone every time a call is made, which reduces the work pressure of each device in the color ring ring service.

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 , it is a schematic diagram of the method steps of playing a CRBT in Embodiment 1 of the present invention. Before the communication process starts, the corresponding CRBT data has been determined according to the current location information of the terminal, and the identification of the terminal can be bound to the determined CRBT data. Certainly. When the terminal whose identification is bound to the CRBT data becomes the called terminal during the call, the CRBT service server plays the CRBT data corresponding to the determined current location information of the called terminal to the calling terminal during the current call. This embodiment one includes the following steps:

Step 101: the calling terminal initiates a call request to the called terminal.

Step 102: The MSC of the calling terminal initiates a CRBT play request to the CRBT service server through the carried identifier of the called terminal, requesting to play the CRBT data of the called terminal.

Step 103: The CRBT service server obtains the CRBT data bound to the CRBT identifier according to the predetermined correspondence between the CRBT identifier of the called terminal and the CRBT data corresponding to the location of the called terminal.

Step 104: The CRBT service server plays the CRBT data bound with the identifier of the called terminal to the calling terminal during the call.

According to the solution from step 101 to step 104, before the call process starts, the color ring data corresponding to the location information of the called terminal has been determined, and during the call process, the corresponding color ring data is directly obtained according to the identifier of the called terminal in the color ring play request The equipment in the color ring service does not need to confirm the data of the called terminal again, which reduces the workload of the equipment in the color ring service. When a large number of call services appear in parallel, the equipment in the color ring service can also process each The ring back tone service required in the call service.

In the first embodiment, the predetermined corresponding relationship between the identifier of the called terminal and the color ring data corresponding to the location of the called terminal can be obtained according to the method shown in FIG. 2:

Step 201: Detect the location of the terminal, and judge whether the location of the terminal changes, and if so, execute step 202; otherwise, continue to execute this step.

The methods for detecting the location of the terminal in this step include but are not limited to the following two:

The first detection method: the positioning server cooperates with the built-in Global Positioning System (GPS) or Assisted Global Positioning System (AGPS) and positioning satellites to obtain the latitude and longitude information of the terminal's location. When the latitude and longitude information of the terminal changes, and the amount of change reaches a set first threshold, it can be considered that the location of the terminal has changed.

The first threshold here may refer to a certain value of longitude and/or a certain value of latitude.

The second detection method: roughly determine the location of the terminal according to the location of the base station currently accessed by the terminal. It can be considered that the position of the terminal does not change when it moves within the coverage area of the same base station, but when the base station accessed by the terminal is transferred from one base station to another, the position of the terminal changes. It can also be considered that when the base station accessed by the terminal is transferred from one base station to another, the position of the terminal changes only when the distance between the two base stations reaches a set second threshold.

The second threshold here may refer to a distance of a certain value.

Step 202: Determine the current location information of the terminal.

This step can be similar to step 201. The terminal can determine the current location information of the terminal according to its built-in GPS or AGPS, or the MSC can determine the location of the base station the terminal is currently accessing. Since the terminal is close to the base station it is accessing, therefore, The current location information of the terminal can be estimated according to the location of the base station currently accessed by the terminal.

Step 203: Determine whether the current location information of the terminal changes within the set time period, if yes, return to step 202; otherwise, execute step 204.

Through this step, the process of determining the color ring tone can be avoided too frequently. It is generally believed that when the terminal is in a relatively stable state, that is, the position of the terminal does not change within a certain period of time, the process of color ring selection is performed.

This step is not a necessary step to achieve the purpose of the invention, and it is also possible to jump directly from step 202 to step 204 without determining whether the current location information has changed within the set time period.

Step 204: According to the correspondence between the location information and the CRBT data, determine the CRBT data corresponding to the current location information of the terminal from the CRBT data corresponding to the terminal.

In this step, a plurality of CRBT data corresponding to the terminal in the CRBT library is determined according to the identification of the terminal (such as a telephone number, etc.).

The CRBT library may pre-store the corresponding relationship between CRBT data and location information. In the corresponding relationship: one location information corresponds to one CRBT data, and one CRBT data corresponds to at least one location information. The first embodiment does not limit the setting conditions of the corresponding relationship between the CRBT data and the location information, which may be set by the user or generated by the system according to certain rules.

When it is necessary to determine the current CRBT data of the terminal for a certain terminal, according to the corresponding relationship between customized CRBT data and location information, find out the location information corresponding to the location information determined in step 202 from a plurality of CRBT data corresponding to the terminal in the CRBT database. For the CRBT data, further, parameters related to the CRBT data may be found according to the location information determined in step 202, and then the CRBT data corresponding to the current location information of the terminal may be synthesized.

Step 205: Establish the determined corresponding relationship between the color ring back tone data and the identification of the terminal.

In this embodiment, initially, a CRBT data may be bound with the identifier of the terminal, and the CRBT data at this time may be the CRBT data set by the user. When the position of the terminal changes for the first time, after performing steps 101 to 104, obtain the color ring data corresponding to the position information after the first conversion, and obtain the color ring data corresponding to the position information after the first conversion The initially set CRBT data is replaced to obtain the binding of the updated CRBT data and the identification of the terminal. By analogy, when the position of the terminal changes for the second time, the obtained CRBT data corresponding to the location information after the second transformation is replaced with the CRBT data at the time of the first change, and the updated CRBT data and the CRBT data are obtained again. Binding for the identity of the terminal.

In the method from step 201 to step 205, the involved terminal is the called terminal in the method shown in FIG. 1 .

When multiple terminals simultaneously request to determine the corresponding CRBT according to the location information of the terminal, the request of each terminal can be processed in a queue manner, especially if a certain terminal does not receive a response to the last request initiated , the location information of the terminal has changed, and if a request is re-initiated, the previous request can be deleted, and only the latest request can be kept and processed.

The location information involved in the first embodiment can be divided according to administrative regions or street names. For example, when the terminal is located in each area of Beijing, the location information of the terminal can all be "Beijing", and can also be Beijing is divided into Haidian District, Chaoyang District, etc. according to administrative regions. When the terminal is located in Haidian District, the location information of the terminal can all be "Beijing-Haidian District".

Through the method of the first embodiment, the color ring corresponding to the location information of the called terminal is determined before the call process starts, and the corresponding color ring is directly obtained from the device storing the binding relationship between the terminal identifier and the color ring during the call process. The equipment in the service does not need to perform the operation of determining the CRBT, which reduces the working pressure of each device in the CRBT service.

Under the same inventive concept as Embodiment 1 of the present invention, Embodiment 2 of the present invention also provides a device for playing CRBT. As shown in FIG. 3 , the device for playing CRBT includes: a CRBT play request receiving module 11 and a playing module 12, wherein: the CRBT playing request receiving module 11 is used to receive the CRBT playing request containing the identifier of the called terminal, and the CRBT playing request comes from the MSC of the calling terminal during the calling process; the playing module 12 is used to receive The corresponding relationship between the identification of the calling terminal and the color ring data corresponding to the location of the called terminal is obtained, and the color ring data corresponding to the identification of the called terminal in the color ring playing request is obtained, and the obtained color ring data is played to the calling terminal in the calling process.

The device for playing the CRBT also includes a CRBT data determination module 13 and a binding module 14, wherein: the CRBT data determination module 13 is used to determine from the CRBT data corresponding to the called terminal according to the correspondence between the position information and the CRBT data. The CRBT data corresponding to the current location information of the called terminal, the current location information of the called terminal is determined when the location of the called terminal changes; the binding module 14 is used to establish the determined CRBT data and called Correspondence between terminal identifiers.

The device for playing CRBT also includes a time period detection module 15, configured to trigger the CRBT data determination module 13 when it is determined that the current location information of the called terminal has not changed within a set time period.

In the second embodiment, the binding relationship between the CRBT data obtained by the binding module 14 and the identification of the called terminal may change frequently. For example, when the position of the terminal changes once, the transformed position information will be obtained. Corresponding CRBT data, replace the corresponding CRBT data corresponding to the transformed position information with the corresponding relationship between the existing CRBT data and the terminal identification, obtain the corresponding relationship between the updated CRBT data and the terminal identification, and replace each updated Or, when the color ring tone needs to be played each time, the play module 12 obtains the correspondence relationship between the latest color ring data and the terminal identification from the binding module 14.

Embodiment 3 of the present invention also provides a communication system. As shown in FIG. 4 , the communication system includes a positioning server 21, a CRBT library 22, a CRBT determination server 23, a call center 24, and a CRBT service server 25, wherein: the positioning server 21 It is used to detect whether the position of the called terminal changes, and when the position of the called terminal changes, determine the current position information of the called terminal; the CRBT database 22 is used to store the CRBT data corresponding to the called terminal; the CRBT determination server 23 is used for determining the corresponding CRBT data corresponding to the current location information of the called terminal from the CRBT library 22 according to the corresponding relationship between the location information and the CRBT data, and establishing the determined corresponding relationship between the CRBT data and the identification of the called terminal; The center 24 is used for initiating the identification CRBT playing request comprising the called terminal to the CRBT service server 25; The CRBT data corresponding to the identifier of the called terminal is played, and the obtained CRBT data is played to the calling terminal during the call.

The communication system further includes a time period detection module 26, which is used to determine whether the current location information of the called terminal changes within the set time period, and if there is no change, then trigger the color ring back tone to determine the server 23; otherwise, The positioning server 21 is triggered.

The call center in this embodiment may be the MSC of the calling terminal during the call.

The function of the CRBT determining server 23 is the sum of the functions of the CRBT data determination module 13 and the binding module 14 in the second embodiment; and.

The CRBT determination server 23 will use the CRBT data corresponding to the updated location information to update the corresponding relationship between the CRBT data and the terminal identification when the position of the terminal is updated each time, and send the corresponding relationship between the CRBT data and the terminal identification to the CRBT The service server 25; or, the CRBT service server 25 acquires the latest correspondence between CRBT data and terminal identifiers from the CRBT determining server 23.

Through the method, device and communication system provided by the embodiments of the present invention, when the terminal is not performing voice communication, the color ring data of the terminal can be dynamically determined in advance according to the actual location information of the terminal. When the terminal is used as the called terminal in the communication process At the same time, the determined CRBT data is played directly to the calling terminal, which improves the personalization capability of the CRBT service; at the same time, since the process of determining the CRBT data and the communication process are not performed at the same time, even if multiple terminals simultaneously propose to determine the CRBT based on the location information The request for data will not cause delayed service or no response, which reduces the working pressure of the CRBT service server and improves the concurrent capability of the CRBT service server.
