Description

Method for displaying current network operator information

The present invention relates to an operator information display technology, and more particularly to a method capable of displaying information of a network operator currently located in a mobile communication terminal. Background of the invention

With the rapid development of mobile communications, there are more and more users who have roaming requirements across carriers. The so-called cross-operator roaming demand refers to: When a mobile communication terminal roams to a mobile communication network outside its own home network, it is expected to utilize the current The roaming network where it is located continues to communicate. Generally, as long as the roaming agreement is signed between the user's home network operator and the roaming network operator, the roaming network where the user is currently located can support the user to continue communication. For example, when the Chinese mobile communication network roams to Europe, it can pass the local The mobile communication network uses its own mobile communication terminal to make calls. For various needs, operators often want to display their own names on the mobile phones of users who roam to their own networks. For example, carrier A and carrier B have a roaming agreement, and operators of carrier B roam to carrier A. In the network, the operator A wants to display his own carrier name on the user's mobile communication terminal instead of the name of the operator B, and vice versa. However, the existing mobile communication terminal can only display the name of the home network operator. For example, the user 1 is a user registered with the operator A, and after the user 1 roams to the network of the operator B, the user 1 is on the mobile phone. Only the name of carrier A can be displayed, and the name of carrier B cannot be displayed.

The existing mobile communication terminals generally fall into two categories: a mobile communication terminal with a machine card integration and a mobile communication terminal with a separate machine card. Taking a CDMA mobile phone as an example, a CDMA mobile phone with a machine card integration and a CDMA mobile phone with a separate machine card. . For CDMA phones with integrated card and card, There are two methods for displaying the operator name: One is to define the carrier name as a variable in the CDMA mobile phone software code, and assign the operator name variable in the mobile communication terminal to the user home network before the mobile phone leaves the factory. The carrier name is then compiled into a software version for use. The other is to set a carrier name item in the rewritable storage area (NV), and then set the value of the item by inputting a specific password on the interface, or it can be set by dedicated software. It can be seen from the above two implementation schemes that the existing mobile communication terminal can only set the name of the home network operator when the mobile phone is shipped from the factory. Therefore, the operator name of the roaming place cannot be displayed in real time when the user roams, that is, the mobile phone terminal cannot be realized. The local carrier name is displayed.

For a CDMA mobile phone with a separate card, the common implementation is as follows: Store the home carrier name and some prompt information in the UIM card, as shown in Table 1. After the phone is turned on, the relevant data is read from the UIM card, and the display operator condition is used to determine whether to display the home operator name.

Bl = l indicates that the registered system is required to be displayed, b2 to b8 are RFUs; byte 2 is a character encoding, where bl ~ b5 is used to represent character encoding, b6 ~ b8 is RFU; byte 3 is a language indicator; Sections 4 through 35 can be used to display the operator's name, and unused bytes are set to FF.

It can be seen that the scheme can only pre-set the name of the user's home network operator in the UIM card, and cannot display the name of the roaming operator when the user roams, that is, the local operator name cannot be displayed. Summary of the invention

In view of this, it is a primary object of the present invention to provide a method of displaying current network operator information that enables a mobile communication terminal to display local operator information of the network in which it is currently located.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a flowchart of sending a feature notification message;

FIG. 2 is a flowchart of an implementation of an embodiment of the present invention. Mode for carrying out the invention

The core idea of the present invention is: using the existing outgoing message on the network side, the network side places the operator information of the carrier to which the carrier belongs, and sends it to the mobile communication terminal, and the mobile communication terminal displays according to the received information. The carrier information of the network where it is currently located.

Here, the sending message may use an existing feature notification message, and the operation of placing the operator information in the feature notification message may be performed by a mobile switching center (MSC) on the network side. Of course, the feature notification message may also carry other display-related control information, such as: display language indication information, and the like. The operator information may be an operator name or other information related to the operator. The implementation method of the present invention is further described below by taking the operator information as the operator name as an example, and other operator information has a similar processing flow.

Taking a CDMA network as an example, in a CDMA network, there is a feature notification message, which is mainly used to send a notification to a mobile communication terminal when there is no connection or idle state, such as: sending forward notification, message waiting notification Wait.

In the CDMA system, the feature notification message is triggered by the MSC when the CDMA mobile phone performs network registration. The specific process of the feature notification message is as shown in FIG. 1. The mobile communication terminal, such as a CDMA mobile phone, initiates a registration message to the base station system (BS); the BS sends a location update request to the MSC after receiving the location update request; The MSC returns a location update to allow Location update accept to the BS; after receiving the BS, the BS returns a registration accept command Register Accept Order; after that, the MSC sends a feature notification message to the mobile communication terminal.

The feature notification message includes a mobile station notification record (MS Information Records) field, and the specific composition of the field is as shown in Table 2.

As can be seen from Table 2, the Information Record Type field is included in MS Information Records. If the value of Information Record Type is 00000001, the field is used as the Display field. In this case, the information in the field can be directly displayed. On the mobile communication terminal.

Based on this, the present invention utilizes the display function of the Display field in the feature notification message, and the network side places the operator name, or operator name, and related control information of the operator to which the mobile communication terminal is currently located in the Display domain, and then A feature notification message containing the operator name or containing the operator name and related control information is transmitted to the mobile communication terminal.

As shown in FIG. 2, FIG. 2 is a flowchart of an implementation of an embodiment of the present invention. In this embodiment, the method for displaying the name of the local carrier is included in the feature notification message, and the method for displaying the name of the local carrier includes the following steps:

Step 201: Control information related to display that the mobile communication terminal is currently located in the network setting. Here, the control information includes at least preferred language information, English indication information, and native language index. Show information. In practical applications, this step can be omitted if control information is not required.

Step 202: The network side places the set control information and the operator name of the operator to which it belongs to the Display field of the feature notification message. Here, the location of the mobile communication terminal is referred to as the home country, and the operator name includes at least the operator name indicated in English and the operator name indicated in the native language. The specific composition of the Display field is as shown in Table 3.

In Table 3, j is the starting position of the Display field byte, and M/0 is Mandatory or Option, indicating forced or optional. j+2 indicates that the j+2th byte is a preferred language byte. In one byte of the preferred language, the bit bl is equal to 0, indicating that English is preferred; the bit M is equal to 1, indicating that the native language is preferred; Bits b2 to b8 are reserved bits (RFU). In general, the mobile communication terminal can support one or more languages and English is mandatory, so it can be set: if the mobile communication terminal supports the preferred language, the operator name is displayed in the preferred language, if the mobile communication terminal does not support the preferred Language, the operator name is displayed in English by default.

The j+3th byte is an English indication, which is used to give the value corresponding to English. According to the standard, the byte takes the value 00000001. The j+4 bytes are the native language indication, which is used to give the value corresponding to the language of the current location of the mobile communication terminal. The specific value of the byte according to the standard is shown in Table 4, for example: When roaming to France, the native language indicates a value of 00000010. The j+5 to j+36 bytes are the local carrier names in English. The unused bytes are set to FF; the j+37 to j+68 bytes are the local carrier names indicated in the native language, and the unused bytes are set to FF.

Step 203: The network side carries a specific notification message with the set Display field, and when the mobile communication terminal performs network registration, it is sent to the current mobile communication terminal.

Here, the performing network registration refers to registration of the mobile communication terminal to the current belonging network due to various reasons. Since there are many cases in which the mobile communication terminal performs network registration, and the mobile communication terminal only changes or restarts when the area is located, the operator's change may occur, and the operator of the network where the mobile communication terminal is located is the other time. It does not change, so in order to prevent the mobile communication terminal from frequently updating the display of the operator name, the mobile communication terminal can be controlled to be triggered only when the power-up registration and the zone-based registration are performed. The MSC sends a specific notification message carrying the Display domain.

Step 204 206: After receiving the specific notification message, the current mobile communication terminal extracts the information in the Display field of the message, and determines whether it supports the preferred language according to the obtained information. If yes, the local carrier name corresponding to the preferred language is displayed. If not, the local carrier name is displayed in English.

Here, the specific operation of determining whether the user supports the preferred language is: the mobile communication terminal first takes out the value of the j+2 byte bit M, determines whether the current preferred language is English or native language, and if the preferred language is native, then extracts j+ The value of 4 bytes, and then the obtained native language indication value is matched with the value corresponding to the language supported by itself. If the matching is successful, the current mobile communication terminal supports the native language, that is, supports the preferred language, otherwise, the current mobile communication is indicated. The terminal does not support native language, that is, does not support preferred language.

If the current mobile communication terminal supports the native language, the mobile communication terminal takes out the content in j+37~j+68 for display; if the current mobile communication terminal does not support the native language, the mobile communication terminal takes out j+5~j+36 The content is displayed.

In the actual application, if the Display field in the specific notification message does not contain the control information and only the local carrier name, the step can be as follows: The mobile communication terminal directly obtains and displays the local carrier name carried in the Display domain.

For example, assume that mobile communication terminal A supports English and Chinese, and the values of English and Chinese are 00000001 and 00000110, respectively. After the mobile communication terminal A roams to the SKT network in Korea, the mobile network wants to display the local carrier name, that is, SKT, in the native language, that is, Korean. Therefore, the value of the j+2 byte bit bl of the Display field is set to 1 by the network side. The value of the Mandarin indication is 00000101, and the SKT indicated by the English and the SKT indicated by the Korean language are respectively filled in the corresponding bytes of the Display field; the mobile communication terminal A generates the area switching registration due to the change of the location of the area, and the mobile communication terminal A triggers The MSC sends a specific notification message; after receiving the specific notification message, the mobile communication terminal A first takes out the value of the j+2 byte of the Display field, and finds that the bit M is equal to 1, indicating that the operator requires display in the native language, then the mobile communication Terminal A then takes the value of 00000101 of the j+4 byte, and then matches 00000101 with the values 00000001 and 00000110 corresponding to the language supported by itself, and finds that the matching is unsuccessful, indicating that the movement is The communication terminal A does not support the native language. Therefore, the mobile communication terminal A takes out the contents of the j+5~j+36 bytes and displays the local carrier name SKT in English.

The method of the present invention can be applied to the mobile communication network of IS95 and IS2000, and the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
