In view of the above problems, an embodiment of the present application provides an affiliation information display method, where when a called terminal receives a service request sent by a calling terminal, because the service request carries information of an operator to which the calling terminal belongs, the called terminal can display information of the operator to which the calling terminal belongs, which is sent by the calling terminal.

The attribution information display method provided by the embodiment of the application is suitable for the communication system 10-1. Fig. 1a shows one configuration of the communication system 10-1. As shown in fig. 1a, the communication system 10-1 includes: a calling terminal 11 and a called terminal 12. Wherein, calling terminal 11 is connected with called terminal 12 in communication.

The calling terminal 11 and the called terminal 12 in this embodiment of the application may be various handheld devices, vehicle-mounted devices, wearable devices, computers, smart home devices, or intelligent office devices with communication functions, which is not limited in this embodiment of the application.

Example one

A detailed description will be given below of an attribution information displaying method provided by an embodiment of the present application, with reference to the communication system shown in fig. 1a and the attribution information displaying apparatus shown in fig. 2 (or fig. 3).

Fig. 4 is a flowchart illustrating a method for displaying attribution information according to an embodiment of the present application. As shown in fig. 4, the attribution information displaying method includes the following S401-S403.

S401, the calling terminal determines the operator information to which the calling terminal belongs according to the user identification card.

Currently, a terminal usually includes two numbers, one is a mobile station international subscriber identity (MSISDN), i.e., an Integrated Services Digital Network (ISDN) number of a mobile subscriber, which is a number that can uniquely identify the mobile subscriber in a public switched telephone network (pstn) switching network numbering plan. It is simply understood that the MSISDN is the mobile phone number. Another number of the terminal is an International Mobile Subscriber Identity (IMSI). The IMSI is a flag for distinguishing a mobile subscriber, and is stored in a Subscriber Identity Module (SIM) card, and is used as effective information for distinguishing a mobile subscriber. It is simply understood that the IMSI is an identification number of the SIM card, and each SIM card can be distinguished.

The IMSI consists of a string of decimal digits with a maximum length of 15 digits. The IMSI consists of three parts: a Mobile Country Code (MCC), a Mobile Network Code (MNC), and a Mobile Subscriber Identification Number (MSIN). Wherein the MCC is 3 bits in length; MNC length is determined by the value of MCC, which can be 2 digits (european standard) or 3 digits (north american standard); the value of MSIN is assigned by the operator.

When a user corresponding to the calling terminal carries the number and changes the network, the MSISDN number is unchanged, but because the IMSI is stored in the SIM card of the user and the user needs to go to a business hall corresponding to an operator to change the SIM card when carrying the number and changing the network, the calling terminal can update the SIM card of the calling terminal while changing the operator.

In this case, the calling terminal may determine, from the SIM card, operator information to which the calling terminal belongs.

Specifically, the calling terminal may determine, according to the MCC and MNC in the IMSI of the SIM card, operator information to which the calling terminal belongs.

Optionally, the calling terminal may determine, according to a classification of a Public Land Mobile Network (PLMN) in the SIM card, operator information to which the calling terminal belongs.

Specifically, PLMNs include the following 9 classes: registered PLMN (registered PLMN), equivalent PLMN (equivalent PLMN EPLMN), Equivalent Home PLMN (EHPLMN), Home PLMN (HPLMN), visited PLMN (visited PLMN, VPLMN), user controlled PLMN (UPLMN), operator controlled PLMN (OPLMN), Forbidden PLMN (FPLMN), and Acquirable PLMN (APLMN).

Illustratively, the HPLMN is a PLMN of the SIM card of the user corresponding to the IMSI. EHPLMN equivalent home PLMN. The operators corresponding to the HPLMN may have different numbers, for example, operator a has 46000, 46002 and 46007. 46002 is EHPLMN relative to 46000, and the operator writes into the SIM card when burning the card. The EPLMN is equivalent to the PLMN, the EPLMN is the peer-to-peer network of the last registered network, and is equivalent to the RPLMN. If the user is at home then EPLMN EHPLMN. If roaming, EPLMN is not equal to EHPLMN. The RPLMN is a PLMN registered by the terminal before the last shutdown or offline, and is temporarily stored on the SIM card.

S402, the called terminal receives the service request sent by the calling terminal.

And after determining the operator information to which the calling terminal belongs, the calling terminal sends a service request to the called terminal. After the calling terminal sends a service request to the called terminal, the called terminal receives the service request sent by the calling terminal. The service request carries information of an operator to which the calling terminal belongs; the information of the operator to which the calling terminal belongs is determined according to the subscriber identity module card of the calling terminal.

Alternatively, the service request may be a voice service request, a short message service request, or the like.

And S403, the called terminal displays the information of the operator to which the calling terminal belongs.

And after receiving the service request sent by the calling terminal, the called terminal displays the operator information to which the calling terminal belongs.

The embodiment of the application provides an attribution information display method which is applied to a communication system comprising a calling terminal and a called terminal. The calling terminal is in communication connection with the called terminal. The attribution information display includes:

the called terminal receives the service request sent by the calling terminal. The service request carries information of an operator to which the calling terminal belongs, wherein the information of the operator to which the calling terminal belongs is determined according to a subscriber identity card of the calling terminal. Subsequently, the called terminal displays the information of the operator to which the calling terminal belongs.

Example two

When the called terminal receives the service request sent by the calling terminal, the called terminal can also receive the service request sent by the calling terminal through the calling core network device and the called core network device. Next, a detailed description will be given of another attribution information display method provided by the embodiment of the present application, in conjunction with the communication system shown in fig. 1b and the attribution information display apparatus shown in fig. 2 (or fig. 3).

Fig. 5 is a flowchart illustrating another home information display method according to an embodiment of the present application. As shown in fig. 5, the attribution information displaying method includes the following S501-S505.

S501, the calling terminal determines the operator information to which the calling terminal belongs according to the user identification card.

The specific implementation manner of the calling terminal determining the operator information to which the calling terminal belongs according to the subscriber identity module card may refer to the description of S401, which is not described in detail herein.

S502, the calling core network equipment receives a service request sent by the calling terminal.

After determining the operator information to which the calling terminal belongs, the calling terminal adds the operator information to the service request, and sends the service request to the calling core network device. Because the home operator information in the service request may be lost when the calling terminal sends the service request to the calling core network device, the calling core network device determines whether the service request carries the home operator information after receiving the service request sent by the calling terminal.

And if the service request carries the operator information to which the calling terminal belongs, the calling core network equipment sends the service request to the called core network equipment.

If the service request does not carry the attributive operator information, the calling core network equipment acquires the SIM card of the calling terminal and determines the attributive operator information according to the SIM card. Then, the calling core network device adds the attributive operator information into the service request, and sends the service request to the called core network device.

Optionally, when the calling core network device determines the home operator information according to the SIM card, the home operator information may be represented as a PLMN (e.g. 46001), may also be represented as an operator noun (e.g. operator a), and may also be represented as a uniformly planned operator code (e.g. 1241 or T1 is the code of operator a, 1242 or T2 is the code of operator B, and 1243 or T3 is the code of operator C). The granularity of the attribution information can be configured to countries, provinces, cities, etc.

Optionally, when the calling terminal sends a service request to the calling core network device, the calling terminal generally adds the home operator information to a P-Preferred-Identity header field or a FROM header field or a P-Asserted-Identity header field in an INVITE (INVITE) message.

Illustratively, the P-Asserted-Identity contains a Uniform Resource Identifier (URI) and an optional list name (display name). When the calling terminal adds P-Asserted-Identity, the attributed operator information may be added to the display name field.

Optionally, when receiving the service request sent by the calling terminal, the calling core network device may also authenticate the calling number sent by the calling terminal and the affiliated operator information, and determine whether the calling number is legal, so as to prevent a false calling. If the calling number carried by the calling terminal and the attributive operator information are legal, the calling core network equipment can simultaneously perform corresponding transformation on the attributive operator information of the calling number inserted by the calling terminal. If the calling number carried by the calling terminal and the attributive operator information are illegal, the calling core network equipment deletes the calling number carried by the calling terminal and the attributive operator information, and the calling core network equipment inserts the attributive operator information of the calling core network equipment as the attributive operator information of the calling number according to network configuration.

If the INVITE message sent by the calling terminal includes a P-Preferred-Identity header field when the calling terminal sends a service request to the calling core network device, the P-CSCF deletes the P-Preferred-Identity header field, and checks whether a URI identifier filled in the P-Preferred-Identity header field matches one of public user Identifiers (IMPUs) registered by the calling terminal.

If the request is matched with the IP address of the P-CSCF, the P-CSCF inserts into a P-Asserted-Identity header field, the URI identification in the P-Asserted-Identity header field is filled in the P-Asserted-Identity header field, the display-name of the P-Asserted-Identity header field is written into the display-name in the P-Asserted-Identity header field, and the P-CSCF can also supplement and fill the display-name of the P-Asserted-Identity header field according to equipment configuration to increase the attributive operator information.

If not, the P-CSCF shall insert a P-Asserted-Identity header field, fill the default value of the user registration public user Identity in the URI part in the P-Asserted-Identity header field (if there are multiple default values of the public user Identity, the P-CSCF may randomly select one of them, or insert multiple ones), and set the operator information of the home of the calling terminal as the value of the display-name in the P-Asserted-Identity header field by the P-CSCF according to the device configuration.

And if the INVITE message sent by the calling terminal contains the P-Asserted-Identity header field added by the calling terminal when the calling terminal sends the service request to the calling core network equipment, the P-CSCF deletes the P-Asserted-Identity header field added by the calling terminal and inserts a new P-Asserted-Identity header field. And the P-Asserted-Identity header field is inserted into the P-CSCF, the URI value is the telephone number of the registered calling terminal obtained in the registration process, and the display-name value is the value of the P-Asserted-Identity header field of the calling terminal or the display-name value of the P-CSCF which sets the attributive operator information of the calling terminal into the P-Asserted-Identity header field according to the equipment configuration.

S503, the called core network equipment receives the service request sent by the calling core network equipment.

After the calling core network device sends a service request to the core network device, the called core network device receives the service request sent by the calling core network device. The service request carries information of an operator to which the calling terminal belongs; the information of the operator to which the calling terminal belongs is determined according to the subscriber identity module card of the calling terminal.

S504, the called core network equipment sends a service request to the called terminal.

After receiving the service request sent by the calling core network device, the called core network device sends the service request to the called terminal.

And S505, the called terminal displays the operator information to which the calling terminal belongs.

And after receiving the service request sent by the called core network equipment, the called terminal displays the operator information to which the calling terminal belongs.

EXAMPLE III

When the calling terminal or the called terminal signs a restricted number service, the called core network device may also determine the display policy of the called terminal according to the number service of the calling terminal or the called terminal. Next, a detailed description will be given of another attribution information display method provided by the embodiment of the present application, in conjunction with the communication system shown in fig. 1b and the attribution information display apparatus shown in fig. 2 (or fig. 3).

Fig. 6 is a flowchart illustrating another home information display method according to an embodiment of the present application. As shown in fig. 6, the attribution information displaying method includes the following S601-S606.

S601, the calling core network equipment acquires the number service of the calling terminal.

The number service comprises a display restriction service or a forced display service.

The display restriction service is used for indicating that the number information of the calling terminal is not displayed when the calling terminal sends a service request to the called terminal.

The forced display service is used for displaying the number information of the calling terminal when the calling terminal sends a service request to the called terminal.

The number information includes: at least one of a mobile station international subscriber identity, MSISDN, of the calling terminal, or a home operator of the calling terminal.

S602, the called core network equipment receives the number service of the calling terminal sent by the calling core network equipment.

After acquiring the number service of the calling terminal, the calling core network device sends the number service of the calling terminal to the called core network device, and the called core network device receives the number service of the calling terminal sent by the calling core network device.

S603, the called core network equipment acquires the number service of the called terminal.

It should be noted that, in the present application, S601-S602 may be executed first, and then S603 is executed; or S603 can be executed first, and then S601-S602 can be executed; S601-S602 and S603 may also be executed simultaneously, which is not limited in this embodiment of the application.

S604, the called core network equipment determines the display strategy of the called terminal according to the number service of the calling terminal and the number service of the called terminal.

The display strategy is used for indicating the called terminal to display the number information corresponding to the display strategy.

Specifically, if the called terminal signs a forced calling number display service and the calling terminal signs a forced calling number display service, the called core network device determines that the display policy of the called terminal is to display the calling number and the operator information to which the calling terminal belongs.

If the called terminal signs a calling number forced display service and the calling terminal signs a calling number display restriction service, the called core network equipment determines that the display strategy of the called terminal is to display the calling number and the operator information to which the calling terminal belongs.

If the called terminal signs the calling number display restriction service and the calling terminal signs the calling number display restriction service, the called core network equipment determines that the display strategy of the called terminal is not to display the calling number and the operator information to which the calling terminal belongs.

If the called terminal signs the calling number display restriction service and the calling terminal signs the calling number forced display service, the called core network equipment determines that the display strategy of the called terminal is not to display the calling number and the operator information to which the calling terminal belongs.

And S605, the called core network equipment adds the display strategy into the service request and sends the service request added with the display strategy to the called terminal.

After determining the display strategy of the called terminal according to the number service of the calling terminal and the number service of the called terminal, the called core network equipment adds the display strategy into the service request and sends the service request added with the display strategy to the called terminal.

Specifically, when the calling terminal signs a calling number display restriction service, the calling core network device should add a Privacy header field in an INVITE message sent by the calling terminal, set the value to "id", and change the From header field to anonymous.

When the called terminal signs the calling number forced display service and the calling terminal signs the calling number forced display service, the called core network device does not specially process the P-Asserted-Identity header field and passes through to the called terminal.

If the called terminal preferentially displays the FROM header field, in order to ensure the reliability of the FROM header field, the called core network equipment identifies the FROM header field according to the number in the P-Asserted-Identity, the consistency of the FROM header field and the P-Asserted-Identity header field is ensured, and the terminal preferentially takes the number FROM the FROM header field as the calling number to display.

When the called terminal preferentially displays the P-Asserted-Identity, the called core network device does not perform special processing on the P-Asserted-Identity header field, the P-Asserted-Identity header field is transmitted to the called terminal in the INVITE message, and the called terminal preferentially fetches a number from the P-Asserted-Identity header field to be used as a calling number for display.

When the called terminal does not sign a mandatory display service, the privacy field in the INVITE message received by the called core network device is id, and the FROM header field is anonymous (set by the calling core network device), the privacy field and the FROM header field are not processed, and are directly transmitted. If the privacy field in the received INVITE message has id and user, the FROM header field is set to anonymous. The called core network equipment deletes the P-Asserted-Identity according to the Privacy id, optionally deletes the Privacy field at the same time, and then sends a service request to the called terminal.

When the called terminal signs the mandatory display service, the called core network device does not modify the P-Asserted-Identity header field, deletes the whole Privacy header field, and the called core network device directly sends the service request to the called terminal without any change.

When the called terminal does not sign a mandatory display service, the called core network device sets the value of the Privacy header field in the INVITE message to be id. When the value of Privacy in the INVITE session request received by the called core network device is "id", the called core network device deletes the P-Asserted-Identity header field in the session request sent to the called terminal by the called core network device, and changes the From header field to anonymous.

And S606, the called terminal displays the number information of the calling terminal according to the display strategy.

And after receiving the service request which is sent by the called core network equipment and added with the display strategy, the called terminal displays the number information of the calling terminal according to the display strategy.

The called terminal displays the calling number according to the P-Asserted-Identity or the URI of the FROM header field in the received INVITE message, and displays the operator information to which the calling terminal belongs according to the display name. Because the P-Asserted-Identity or FROM header field has been authenticated and checked for validity by the calling core network device, the called terminal can also display the home information of the calling terminal according to the URI part home network domain name in the P-Asserted-Identity or FROM header field.
