Description

 Method and device for processing caller number display during communication

 Technical field

 The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for implementing a caller number display during a communication process. Background of the invention

 The concept of P0C (Call-on-Call based on cellular system) comes from the walkie-talkie, and its user experience is similar to that of walkie-talkies.

-- Simple, fast, half-duplex call. By setting the call group in advance, the user does not need to dial the call, and press and hold a specific button, the voice can be simultaneously transmitted to all other members in the group, and the call and call connection process is completed in an instant. During the P0C call, the receiver can answer without any response, and the call process uses half-duplex mode. When one party is talking, other members can only answer and cannot speak.

 Currently, in the group call network element architecture of the P0C of the 0MA (Open Mobile Alliance), the CF (the P0C server performing the call control function) performs the total control of the group session, and there is only one CF in one group session. PF (POC server performing call participation function) Entity A user, that is, one PF corresponds to one user.

 As shown in Figure 1, it can be seen that the P0C terminal directly interacts with the PF server, and the PF manages a user's session and continues signaling.

The CF interacts to ensure that the session of the P0C terminal is normal.

 In a P0C call, the calling party may request to hide its own number. At this time, the calling party's calling number 'information will not be provided to the called user during the P0C call, that is, the called user in the P0C call will not be able to know. The identity of the calling user who initiated the call.

 The above-mentioned hidden number service can meet the special needs of some users as the calling party. However, in some special cases, the called user must display the calling number for various reasons, for example:

 1. If the called party is a special service number or other important number, that is, the called user has a special identity, it is usually required to display the calling number information; for example, an emergency service center, or a legal listening center;

 2. If the group policy is that the called user with high priority has the right to know the calling number information with low priority, it is necessary to display the low priority calling number information unconditionally;

 3. In the actual communication process, some called users are required to display the calling number information to consider whether to accept the session request, that is, the called user needs to determine whether to establish a session with the calling user according to the calling number information.

 However, according to the current processing of the P0C service, when the calling user requests to hide his own number information, the number information is not displayed to the called user. Therefore, the existing processing cannot satisfy the above requirements, and at the same time, the implementation of the above two functions is not provided in other communication environments where similar requirements exist.

Mode for carrying out the invention

In the communication system, during the service communication between the calling and called users, if the P0C calling user initiates a P0C call, it is desirable to hide the calling number, and the invited called terminal requests the incoming P0C call to display the calling party. Number, at this time, the P0C master is called The called call attribute has a conflict. The purpose of the present invention is to solve the call attribute conflict problem in this case.

 The method for solving the above conflict problem mainly includes: when the calling user initiates a call, and the calling user requests to hide the calling number information, it determines whether to provide the calling number information to the user according to the service attribute information of the calling and called user. Instead of directly processing the calling party number in the manner of making a call to the called user as in the prior art. In the meantime, the present invention may further determine whether the called user accepts the call request and returns corresponding indication information according to the configured attribute information of the called user, so that the calling user knows whether the called user accepts the call initiated by the called user.

 Therefore, the present invention can flexibly determine whether to provide the called user with the calling number information for which the hidden calling number information is applied, according to different identity information of the users in the network. For example, when the called user has a higher priority level or a special identity, it may need to know the calling number information to which the call is initiated, and the present invention can well satisfy such users or services. demand. At the same time, the calling user who has hidden the calling number information can also know whether the called user accepts the call by using the returned indication information. For some specific scenarios, if the called user is authorized, the calling number hidden by the calling user is directly obtained, and the calling number of the calling user is indicated or not indicated in the response message returned to the calling user. Information that can meet the needs of specific applications, such as emergency services.

 The present invention is applicable not only to a P0C (Push-to-Talk over Cellular System) system, but also to any other communication system that provides a service for hiding a calling number. That is, the communication process involved in the present invention is not limited to the P0C session process, and is also applied in other SIP-based session processes such as message service, conference service, video communication, and the like. In summary, the present invention specifically provides two solutions to the above conflict problems:

The first implementation scheme displays the calling number information in a negotiation manner, specifically: when the calling user requests to hide the calling number information, it determines whether the called user accepts the call request and returns according to the configured attribute information of the called user. Corresponding indication information to indicate whether to accept the call initiated by the calling party. At the same time, when the calling user requests to hide the calling number information, and according to the service attribute of the called user, it is determined to display the calling number information, then the calling number can be resolved through the negotiation process between the calling and called users. The problem is displayed. At this time, the master and the called party will negotiate to reach a consensus through message interaction. After that, the corresponding call process continues. The second implementation scheme displays the calling number information unconditionally, specifically: when the calling user requests to hide When the calling number information is used, it is determined according to the configured attribute information of the called user whether the called user accepts the call request and returns corresponding indication information to indicate whether to accept the call initiated by the calling party. At the same time, when the calling user requests to hide the calling number information, and according to the service attribute of the called user, it is determined to display the calling number information, and then according to the level information of the calling user, it is determined whether the conditional information is unconditionally displayed to the called user. The calling number information, |] determines that the calling number information needs to be unconditionally displayed to the called user, and the calling number information is directly provided to the called user. Further, the called user may select information indicating or not indicating that the calling party number information is displayed in the response message. The above two specific implementations provided by the present invention will be described in detail below. First, the specific implementation manner of the first solution provided by the present invention is described in detail by taking the P0C system as an example. In the SIP (Session Initiation Protocol) network, in all communication processes using the calling number restriction display, in consideration of actual needs, in some cases, the called user may require that the calling number must be displayed before considering whether to accept the session request. The invention is in the network A negotiation mechanism is provided to negotiate whether to determine the calling number information to the called user.

 For the P0C user, it is configurable whether it is a request to display the calling number information when calling as a called party, and whether to provide the calling party with the calling party number information as the calling party. Generally, the P0C user can set the service attribute on the P0C server or the terminal, and can also configure the service attribute on the POC XDMS. If the configured service attribute information is on the POC XDMS, the P0C server or the client needs to The POC XDMS query obtains the corresponding service attribute information, and then uses it according to the usage on the P0C server or the P0C client.

 1. When the P0C user is called, the user can set the process of displaying the calling number, including:

 (1) Require any caller to display the number;

 (2) If the other party does not have a hidden number, it will be displayed; otherwise, it will not be displayed;

 (3) Set if the calling number is hidden, whether to directly reject the session request or initiate the calling number display negotiation process; and so on. ,

 2. When the P0C user acts as the calling party, the corresponding settings include -

(1) Set whether to use the calling number to limit the display;

 (2) Whether the calling number display negotiation is supported, and the calling number is accepted when the calling number display negotiation is performed for some specific called numbers;

 Temple Temple.

 In the present invention, when the P0C user receives the session request sent by another P0C calling user as the called party, it determines the pair according to the service attribute information configured on the P0C server or the P0C terminal or the POC XDMS described above. The session request is processed accordingly.

 In the present invention, when the calling user sends a P0C call request message to the called terminal, if the calling party asks to hide the calling number, and the called party requests that the calling number must be displayed, otherwise the negotiation is refused, The calling party initiates a calling number display negotiation process, and sends a negotiation request message to the calling terminal or a P0C server serving the calling terminal; the calling terminal or the P0C server serving the calling terminal receives the negotiation request. At the time, the decision is made according to the user's selection or saved settings. If it can be displayed, the caller's number information is carried in the returned response, otherwise the appropriate error indication information is returned.

 In the present invention, when the service attribute information is configured on the P0C terminal, that is, the called user terminal device, the called user terminal device determines whether to reject the current session request or initiate the calling number display negotiation process. At the same time, in the process, the session request information may also be notified (displayed) to the user of the terminal device (ie, the person holding the terminal) by some means, and the user temporarily decides according to his current situation. Rejecting the current session request or controlling the POC terminal to initiate the calling number display negotiation process, so that the P0C terminal determines whether to initiate the calling number display negotiation process according to the external operation control information input by the user; When the attribute is saved on the P0C server, the P0C server may also represent the called user terminal device. When receiving the session request, whether to reject the current session request or control the P0C terminal device to initiate the calling number display according to the configured service attribute information. The decision of the negotiation process.

In the following, the calling user uses the calling number to limit the display service, and the called user requests that the calling number must be displayed as an example, and the specific processing manner adopted by the corresponding called P0C terminal or the P0C server in the present invention is described. When the calling user uses the calling number to limit the display service, in the initiated session request, the calling number will be hidden using the existing mechanism, when the session request is transmitted to the service processing function entity in the network (for When the P0C service is the P0C server, the called terminal of the corresponding P0C service requests the received P0C call request to display the calling number, otherwise the session negotiation is refused. Therefore, the called P0C terminal and the P0C server can be used. The specific treatment includes:

 (1) The called P0C terminal or the P0C server determines the processing mode according to its own settings: directly reject the establishment of the session, or initiate the message interaction process to reach an agreement through negotiation;

 (2) The called P0C terminal or the P0C server determines the processing mode according to the indication carried in the received P0C call: If the indication can be used to perform the number display negotiation with the calling party, the message interaction process is initiated to perform the number display negotiation, otherwise the direct rejection is performed. The establishment of the session; or, if the indication is not possible to perform the number display negotiation with the calling party, the establishment of the session is directly rejected, otherwise the message interaction process is initiated to perform the number display negotiation.

 For the processing method in the above (2), the calling party side needs to add corresponding indication information to the session request message, and may set the session request message according to the user's service attribute setting when the P0C terminal constructs the session request message, or may When a normal session request message is sent to the POC server serving the calling user, the P0C server increases the setting according to the saved service attribute of the calling party. After the called user terminal device or the P0C server adopts the foregoing processing according to the configured service attribute information, the corresponding calling user terminal device or the P0C server also needs to display the negotiation display sent to the called user terminal device or the P0C server. The request message of the number is processed. The specific processing methods include:

 (1) When the service attribute information is configured on the P0C terminal, that is, on the calling user terminal device, the calling user terminal device determines whether to reject the request or send the calling number to the called user; When the service attribute information is configured on the P0C server, the P0C server may make a decision on behalf of the calling user to display the calling number request according to the saved service attribute information, and reject the request or provide the calling number information to the calling user. Called user

 When the calling user sets the condition of the number display on the P0C server in the network or on the P0C terminal, for example, the number of the calling party is allowed to be displayed for certain numbers or certain groups or POC users of a certain level or higher. On the called terminal, otherwise it cannot be displayed. At this time, the corresponding negotiation message only needs to be sent to the P0C server or the P0C terminal, and the P0C server or the client on the P0C terminal negotiates the P0C negotiation request without user intervention. The message is replied so that the calling number can be displayed at the called party.

(2) The P0C terminal may also notify (display) the negotiation display calling number request information to the user holding the terminal device, that is, the calling user, by the user, and the user temporarily decides to refuse according to his current situation. The request also sends the calling number to the called user, and inputs corresponding external operation information to the terminal device, and the terminal device determines to reject the request or provide the calling number information to the called user according to the corresponding external operation information, thereby allowing In the case, the P0C session request message is modified so that the calling number can be displayed at the called user. In order to further understand the technical solutions provided by the present invention, the present invention will be described below in conjunction with specific application examples. The following embodiment uses the session establishment process initiated by the INVITE as an example to illustrate how to implement the calling number negotiation display process. Therefore, only the main steps are listed. The detailed session establishment process is the same as the existing SIP session establishment process. Detailed. Moreover, in the following embodiments, it is assumed that the calling user accepts the display of the calling number during the negotiation process, and the called user can display the calling number after being able to display the calling number. The work completed the session negotiation process and established a meeting.

 The processing of the first embodiment of the first implementation scheme is as shown in FIG. 2, and specifically includes:

 The calling user, that is, the P0C terminal 1 selects the number hiding. When the INVITE message is sent to the called terminal P0C terminal 2, the called terminal decides to initiate the negotiation process, requesting the calling party to carry the calling number for display, thus returning a The error response Response message is sent to the calling user, and the response indicates that the called party requests the calling party to provide the number display, that is, the Response message needs to be able to indicate that the calling party is called because the calling number cannot be displayed and the session negotiation is refused;

 After the calling terminal receives the error response indication message, if the calling user determines to select to display the calling number, the calling user may choose to re-initiate a service request, where the calling number is not hidden, that is, the session restarted by the calling user. The calling number is no longer hidden in the request, so the new session will be established successfully.

 In this embodiment, the POC server serving the called terminal (such as the POS server PF2) may also terminate the request INVITE message instead of the called user, and return an error response; likewise, the calling user's POC server (such as the P0C server) PF1) may also terminate the error response message instead of the caller responding to the error response message, such as providing the called party with the calling number information, or refusing to provide the calling number information. The processing of the second embodiment of the first implementation scheme is as shown in FIG. 3, and includes:

 When the calling user selects the number to hide and sends the session request INVITE (1) message to the POC server PF2 serving the called terminal in the called network, the P0C server PF2 finds the called terminal according to the setting saved by the called terminal. Require that the calling number must be displayed to accept the session, then initiate a new session INVITE (2) to obtain the calling number information;

 Sending the new INVITE (2) to the calling user, requesting the calling user to transmit the calling number information, which carries information related to the previous request of the tongue for the calling user to refer to, and the calling user receives the information according to the The request message determines whether to send the calling number. If it is sent, the calling number is returned to the P0C server PF2 of the called terminal in the response message. Otherwise, the failure response message is returned, and the session establishment process on the called side fails; After receiving the response message including the calling number, the INVITE message is sent to the POC terminal 2, and an acknowledgment message is returned to the calling user, and the two message initiation sequences are not sequentially defined.

 In this embodiment, the POC server serving the called terminal may also send a P0C server serving the calling terminal when initiating a new session request, and the POC server determines whether to provide the calling according to the setting saved by the calling user. number. The third implementation of the first implementation scheme is as shown in FIG. 4 and FIG. 5, and specifically includes:

 If the P0C caller wishes to hide the calling number from the called party, but some called calls must display the calling number to be connected, the calling number is displayed by negotiating with the calling party.

 Before describing the embodiment, the corresponding hypothesis is described first:

 P0C terminal 1, assuming its number is - "PoC User A" <sip : PoC-UserA@networkA. net)

 POC terminal 2, assuming its number is:

"PoC User B"<sip : PoC-UserB@networkB. net> The POC terminal 2 will set the service attribute to the incoming call in the PF2 server to negotiate the display of the calling number, PF2 will save the attribute of the P0C terminal 2, and if the incoming call requests to hide the calling number, the negotiation process mechanism will be initiated.

 The calling number display negotiation process when the P0C terminal 1 calls the P0C terminal 2 will be described below, and specifically includes: Step 41: When the P0C terminal 1 calls the P0C terminal 2, the P0C terminal 2 is not expected to see its own number. In addition to the necessary information in the basic call message, the header field is required in the message, indicating that the P0C terminal 1 does not want to display its own number "PoC User A" <sip: PoC-UserA@networkA.net>, the message contains The specific information is as follows:

 P- Preferred- Identity: "PoC User A" <sip : PoC~UserA@networkA. net)

 Privacy: Id

 The Id (identification) information carried in the Privacy (private) domain in the above message indicates that the P0C terminal 1 chooses to hide its own calling number information;

 Step 42: The PF1, which is the proxy P0C terminal 1, receives the INVITE message sent by the P0C terminal 1, and sends the message to the CF. The special message header field is:

 P-Asserted- Identity: "PoC User A" <sip :PoC-UserA@net orkA. net>

 Privacy: Id

 Step 43: After the relevant analysis of the CF and the completion of the relevant call preparation, the CF will initiate a call to the P0C called party. Since the calling party only invites the P0C terminal 2, the CF will generate an INVITE message to the PF2, in addition to the call center. In addition to the information required, the special message header fields are:

 P— Asserted- Identity: "PoC User A〃 <si : PoC-UserA@networkA. net)

 Privacy: Id

 Step 44: After receiving the INVITE message, the PF2 determines that the POC terminal 1 needs to hide the calling number, and the service attribute indication of the P0C terminal 2 can negotiate to display the calling number. At this time, the PF2 sends a 183 response (processing) to the CF. The message in the message indicates that the calling number needs to be displayed through the XML (Extensible Markup Language) message body to continue the call;

 Incoming- session- cnip (name of a message unit displayed by the calling number, CNIP: Calling Name Presentation) The active "true" attribute indicates that the called party must request the calling number to be displayed, if active-"false" , the caller indicating that the called party does not force the incoming call must display the calling number;

 After the PF2 sends the 183 response message, it immediately starts the timer and waits for the negotiation result. If the timer expires, the call will be terminated and the failure response message will be returned, that is, the call fails.

 The 183 response message contains the following information -

Content-Type : application/poc~service+xral XML MIME BODY

<?xml version="l. 0"encoding="UTF-8"?> <poc- service

 <incoming-session-cnip active true〃>

 </ cal 1 er-privacy>

 </ poc - service >

 Step 45: After receiving the 183 response sent by the PF2, the CF learns that the POC is called to negotiate with the calling party to display the calling number, and the CF will generate a 183 response message for the P0C terminal 1 and send it to the PF1, where the message is represented by the extended message body. The called party asks to display the calling number, and the message contains the following information:

 Content-Type : application/poc-service+xml

 XML MIME BODY

 <caller-privacy>

 Incoming- session- cnip ac"tive true〃>

 </caller~privacy>

 </ poc- service >

 Step 46: After receiving the 183 response, the PF1 transparently transmits the result to the calling POC terminal 1. The POC terminal 1 promptly prompts the calling party through the menu selection. The called party is required to display the calling number to connect the calling party. The user can manually select the option to agree to display the calling number or disagree to display the calling number;

 Step 47: After the calling user selects, the terminal performs the PRACK (acknowledgement message of the temporary response, the acknowledgement message of the Provisional Responses) message in the XML message body according to different selections, and is used to indicate whether the calling party is willing to display the calling number; Use outgoing-session-cnir (calling caller number restriction display, cnir: calling name Restriction) to indicate the caller's calling number limit display (hide caller number) attribute of the calling party, when active="true" Indicates that the caller must hide the calling number from the called party; when active="false" indicates that the calling party agrees to display the calling number;

 P0C terminal 1 The user chooses to agree to display the calling number. In the PRACK message, it is expressed as:

 Content-Type : application/poc-service+xml

XML MIME BODY <?xml version="l. 0" encoding= ^/ UTF-8 ^, ?>'

 <poc— service

 <outing- session- cnir ac"tive=〃false〃>

 </caller~privacy>

 </ poc- service >

 Step 48: After receiving the PRACK message, the PF1 forwards to the CF, and the content of the extended message does not change, as follows:

 Content-Type : application/poc-service+xml

 XML MIME BODY

<?xml version="l. 0" encoding="UTF— 8"?>

 <poc- service

 Xmlns^^urn: oma: arams: xml: ns: poc: poc- service"

 <outing~session~cnir active=〃false〃>

 </caller-privacy>

 </ poc- service >

 Step 49: The CF receives the PRACK message sent by the calling terminal, and resolves whether the calling party is willing to display the calling number after the negotiation, records the calling party's selection in the CF, and creates a PRACK message to be sent to the PF2, and the corresponding PRACK. The information contained in the message includes:

Content-Type : application/poc-service+xml

 XML MIME BODY

<?xml version^l. 0" encoding="UTF-8"?〉

 <poc- service

<outing- session— cnir active="false"> </caller-privacy>

 </ poc - service >

 Step 410: After receiving the PRACK message sent by the CF, the PF2 parses the result of the calling party negotiation.

 If the calling P0C terminal is willing to display the calling number, PF2 forwards the INVITE message received in step 3 to the P0C terminal 2, and the message carries the calling number. The message contains the following information:

 P- Asserted- Identity: "PoC User A" <sip:PoC-UserA§networkA. net>

 Step 411: After receiving the invitation, the POC terminal 2 will immediately respond to the PF2 with a successful response 2000K, and bring the corresponding media information. Step 412: PF2 forwards 2000K to CF.

 Step 413: The CF receives the 2000K message of the PF2, and generates a 2000K message for the calling P0C terminal 1, and sends the message to the PF1. Step 414: After receiving the 2000K message of the CF, the PF1 forwards to the calling P0C terminal 1.

In FIG. 4, _£ said session request message may be sent to the called user terminal 2 P0C process, by a similar process to process.

 In the process shown in FIG. 4, if the calling user does not want to display the calling number when the P0C terminal 1 prompts whether to agree to display the calling number information, the corresponding processing flow is as shown in FIG. 5, which specifically includes:

 Steps 51 through 56 are the same as steps 41 through 46 described above and will not be described in detail herein.

 Step 57: If the calling P0C terminal 1 is unwilling to display the calling number, the message PRACK will be constructed, and the calling party in the BODY (message body) will not display the calling number. After the PRACK is constructed, it will be sent to the PF1.

 The outing-session-cnir attribute, active="true" indicates that the caller is not willing to display the calling number. The corresponding message contains the following information:

 Content-Type: application/poc-service+xml

 XML MIME BODY

 <?xml version=〃l. 0〃 encoding^^UTF-S^?)

 <poc— service

 Xmlns^urn: oma: params: xml: ns: poc: poc- service"

 <outing- session- cnir active=〃true〃>

 </caller-privacy>

 </ poc- service >

 Step 58: After receiving the PRACK message, PF1 forwards the message to CF. The message contains the following contents:

 Content-Type: appl i cat ion/poc-servi ce+xml

XML MIME BODY <?xml version ^{= /} l. encoding'="UTF- 8"?>

 <poc~service

 <outing-session-cnir active= 'true >

 </caller-privacy>

 </ poc - service >

 Step 59: The CF determines that the calling party is unwilling to display the calling number. The CF records the calling party's selection, and creates a PRACK message for the called party. The message is filled with an indication that the calling user does not display the calling number.

 The outing-session-cnir attribute, active-"true" indicates that the caller is not willing to display the calling number. The corresponding message contains the following information:

 Content-Type : Application/poc-service+xml

 XML MIME BODY

 <?xml version-^l. 0" encodingCUTF- 8〃7>

 <poc— service

 Xmlns=〃urn: oma: arams: ml: ns: oc: poc- service

 <caller-privacy>

 <outing~session-cnir active=〃t e〃>

 </caller-privacy>

 </ poc - service >

 Step 510: After receiving the PRACK message, the PF2 parses out whether the calling POC terminal 1 is still unwilling to display the calling number, and rejects the INVITE request on behalf of the P0C terminal 2, and responds to the CF 403, that is, returns a corresponding indication to the calling user. information.

 Step 511: After receiving the 403 response sent by the PF2, the CF finds that the called P0C terminal 2 refuses to receive the request, and generates a 403 response to be sent to the calling P0C terminal 1 through the PF1.

 Step 512: After receiving the 403 response sent by the CF, the PF1 forwards the message to the calling P0C terminal 1, and the P0C terminal 1 displays the call to the user is rejected.

It should be noted that, in the foregoing step 57, after the P0C calling user receives the message indicating the calling party returned by the P0C called user, if the P0C calling user is not willing to display the calling number information, the calling party After receiving the 183 response, the P0C terminal may not send a PRACK message but directly send a CANCEL message to cancel the call. The processing of the fourth embodiment of the first aspect is as follows: '

 The calling user selects the number to hide. When the request message is sent to the P0C server served by the P0C terminal of the calling user in the calling network, the P0C server determines whether to hide according to the number according to the setting saved by the calling user's P0C terminal. Implementing to encrypt the calling number. If the corresponding called number is allowed to display the calling number, the calling number in the request message is not hidden, otherwise it is hidden, and then if the called terminal or the called P0C server also makes a negotiation request The calling number is sent, and the calling user's P0C server can directly reject the corresponding negotiation request according to the saved setting of the calling terminal. It can be seen that, in the solution, the P0C calling party and the P0C called party can solve the problem of calling number display by means of negotiation. When the P0C called attribute requires the incoming call, the calling number needs to be displayed, and the message is the same as the main message. It is called negotiation, and the user of the calling P0C terminal 1 can manually select whether to display the calling number. In the following, the specific implementation manner of the second solution provided by the present invention will be described in detail by taking the P0C system as an example. When the P0C calling user subscribes to the service indicated by the calling number restriction (that is, the calling party number information is required to be hidden), the called user will not be able to see the calling party's number. As mentioned above, in special cases, some P0C called parties need to display the calling number unconditionally. For example, the P0C called number is a special service number. As a P0C special service number terminal, it usually has unconditional right to know the P0C calling party. That is, you need to know the calling number information unconditionally.

 Therefore, in the second implementation provided by the present invention, when the calling party that has signed the calling number restriction display service initiates a call, if the network side determines that the called user needs to display the unconditionally according to the service attribute information of the called user, When the number information is called, the calling number information is unconditionally provided to the called user to meet special needs. The service attribute information may be priority information of the user or other difference information.

 For example, if the P0C calling user subscribes to the calling number restriction display service, when the P0C calling party calls a P0C group, if the group's service attribute information (ie, the calling policy) is set to the higher priority called party priority A low-level caller has an unconditional right to know, and a P0C called by the same priority or low priority will have no such privilege. At this time, the P0C server performs different processing for the called terminals of different priorities, and for the called user with higher priority than the calling user, the calling number can be obtained, and the effect of unconditionally displaying the calling code is achieved; The called user with the same priority as the calling user or lower than the priority of the calling user will not be able to obtain the calling number, that is, the calling number restriction display. The specific implementation of the second solution provided by the present invention will be further described below.

 In the SIP (Session Initiation Protocol) network, in all communication processes using the calling number restriction display, in some cases, the calling number needs to be unconditionally displayed to a specific called user in consideration of actual needs. The realization is precisely to meet this demand = ■

When the calling user uses the calling number to limit the display service, in the initiated session request, the calling number will be hidden using the existing mechanism, when the session request is transmitted to the service processing function entity in the network, The function entity can determine whether it is necessary to implement unconditional number display for some called users by querying the configuration information of the local database (that is, the configured service attribute information) or querying the configuration information saved by other databases in the network: If unconditional display is required, the caller number restriction display set by the calling user is cancelled, and the session request is sent to the called user. At the same time, the service processing function entity may also notify the calling user about the calling number restriction display by some mechanism. Cancelled, and information about which called user was canceled;

 If the unconditional display is not required, the service processing function entity continues to forward the service request to the called user according to the existing implementation, and the called party will not see the calling number.

 In the above description, when the service processing function entity notifies the calling user about the cancellation of the calling number restriction display and the cancellation of the information of the called user, the mechanisms that can be used include:

 1. The calling user signs the service processing function entity when registering on the network (SUBSCRIBE), so that when the service processing function entity cancels the calling number restriction display, the NOTIFY message is sent to the calling user. Notify relevant information;

 2. When the service processing function 'entity cancels the caller number restriction display, the message MESSAGE service is used to send relevant notification information to the calling user;

 3. When the service processing function entity cancels the display of the calling number restriction, when receiving the response message of each called user, adding information about canceling the display of the calling number restriction is added to the response message, so as to facilitate the calling party. The user is informed of relevant information;

 4. The service processing function entity may also use other messages to notify the calling user, such as SIP INFO (Session Initiation Protocol Information) message, or use other protocols to implement this function, such as HTTP (Hypertext Transfer Protocol), etc. This will be detailed again. The method of the present invention will be described below with reference to the accompanying drawings in a specific application example.

 In the application example, an embodiment in which a P0C terminal 1 as a calling user calls a special service number as a called ffl is described. First, the following is assumed:

 P0C terminal 1, assuming its number is:

 - "PoC User A" <sip : PoC-UserA@net orkA. net), the user has signed the calling number restriction display service; P0C terminal 2, assuming its number is:

 "PoC User B〃 <sip : PoC-UserB@networkB. net>, the user is a special service number, and the caller number information must be unconditionally known.

 According to the special requirements, similar to the switches in the circuit domain, some numbers are set as special service numbers through the data configuration in the P0C server CF that performs the call control function, and the data configuration is saved in the CF. Before the called user of the P0C service is connected, the CF will scan and analyze the data configuration of the special service number. If the called party is a special service number, the corresponding special processing will be performed. That is, when the P0C terminal 1 calls the number of the P0C terminal 2, it is determined by the CF whether or not the calling number is displayed. According to the above assumption, as shown in FIG. 6, the corresponding processing process includes the following steps:

 Step 60: The P0C terminal 1 signs the contract with the P0C server CF, and through the SIP SUBSCRIBE (Session Initiation Protocol Description) message, the P0C server CF can return the notification message when the calling number restriction display is cancelled.

Step 61: When the P0C terminal 1 calls the P0C terminal 2, the P0C terminal 2 is not expected to see its own number. In addition to the necessary information in the basic call message, the message needs to be in the lead field, indicating that the P0C terminal 1 is unwilling. Show your number "PoC User A" <sip :PoC-UserA@networkA. net), the corresponding message contains the following information:

 P- Preferred—Identity: "PoC User A" <sip :PoC-UserA@networkA. net>

 Privacy: Id

 Step 62: The PF that is the proxy POC terminal 1 receives the INVITE message sent by the POC terminal 1, and sends the message to the CF. The special message header field is:

 P- Asserted- Identity: "PoC User A" <sip:PoC-UserA@networkA. net)

 Privacy: W

After the CF receives the INVITE request, the value of the Privacy header field is Id, that is, the caller wants to hide the display of the calling number, but by querying the configuration of the special service number data in the CF, the caller is found to be called by the calling party. The calling number is a special service number. Therefore, the CF decides to display the calling number information to the P0C terminal 2 corresponding to the special service number unconditionally.

 Steps 63 to 66: Display the calling number notification process unconditionally;

 The CF will notify the P0C terminal through NOTIFY that the called party will display its number unconditionally, and can also display to the calling party which of the called users unconditionally displays the calling number information;

 The notification process CF can select a notification based on a predetermined relevant policy.

 Step 67: The execution of the step and the step 63 have no relationship, and can be performed at the same time. The CF decides to display the calling number to the P0C terminal 2 unconditionally. At this time, the CF initiates an INVITE call to the P0C terminal 2, and the message will be P-Asserted- The Identity (with calling party number) header field, without the Privacy header field or the value of the Privacy header field is none, indicating that the calling number information is no longer hidden.

 P- Asserted- Identity: "PoC User A" <sip:PoC-UserA@networkA. net>

 Step 68: The POC server that is the PF function of the proxy POC terminal 2 transmits the message to the POC terminal 2. After receiving the call request, the POS terminal 2 detects that there is a P-Asserted-Component header field in the message, and the POC terminal 1 is The number is displayed to the user, and the P0C terminal 2 user immediately knows that it is a POC call sent by "PoC User A" <sip: PoC- UserAtoetworkA.net>. ·

 Step 69 to step 610: The POC terminal 2 requests a successful response to the server for the session, so as to return the corresponding indication information to the calling user, indicating that the call is successfully established;

 Step 611 to step 612: After the CF receives the successful response of the first called party, the group session enters an active state, and the caller returns a successful response.

 In addition to notifying the calling user through the subcribe/notify mechanism in the above figure, the calling number is unconditionally displayed to the called user, and the notification can also be implemented through the MESSAGE mechanism. The corresponding implementation process is shown in Figure 7, and The difference achieved in 6 is only different from the message that informs the calling user, and the other processing is the same.

In addition, the present invention may also add an indication to the called user after receiving the response message of the called POC terminal 2, indicating that the calling number is unconditionally displayed for the called user, as shown in FIG. Corresponding indication information is added to the 2000K message of the P0C terminal 1. A second implementation of the second aspect of the present invention, as shown in Figure 9, is described as follows: If the policy of the POC group is that the high-priority member has an unconditional right to know the low-priority calling number, when the low-priority P0C calling party calls the P0C group, if the low-priority calling party wishes Hiding their own number, the CF will ruling the member who is prioritized than the calling priority, and the called party will display the calling number unconditionally. The remaining members will not be able to display the calling number.

 The prerequisites for implementing this embodiment are:

 Create a P0C group poc_group in the POC XDMS (the XML document management server of the P0C), including the POC terminal 1, the terminal 2, and the terminal 3. The terminal 2 has the highest priority, the terminal is the first, and the terminal 3 is the lowest; The described POC XDMS is a server that stores data such as P0C group information, personal contact list, and the like in the P0C system.

 The policy needs to be determined in the attribute domain of the group: 成员 The priority member has the right to display the calling number unconditionally for the low priority calling party. These attributes will be returned with the group member list when the CF to XDMS acquires the group. Give CF.

 According to the above assumption, as shown in FIG. 9, the P0C terminal call group process includes:

 Step 90: The P0C terminal 1 signs the contract with the P0C server and passes the SIP SUBSCRIBE (Session Initiation Protocol Description) message, so that the P0C server can notify itself when the calling number restriction display is cancelled.

 Step 91: When the P0C terminal 1 calls the group poc_group, the group member is not expected to see the number of the group, and the necessary information is included in the basic call message, and the message field is required to indicate the P0C terminal 1 Unwilling to display your own number "PoC User A" <sip :PoC-UserA@networkA. net), the message contains the following:

 P- Preferred- Identity: "PoC User A" <sip :PoC-UserA@networkA. net>

 Privacy: Id Step 92: As the proxy POC terminal 1, the PF receives the INVITE message sent by the POC terminal 1, and sends the message to the ®CF. The special message header field is:

 P- Asserted- Identity: "PoC User A〃 <sip :PoC-UserA@networkA. net>

 Privacy: Id

Step 93: After receiving the INVITE message, the CF records the related information. Because it is a predefined group call, the group member ID and related group attributes are sent to the POC XDMS according to the group ID.

 Step 94: After receiving the request, the POC XDMS server indexes the group information through the group ID, and returns the group member list and related attributes to the CF.

 After the CF receives the response message, the CF will check the calling display policy of the group because the calling party does not want to display the calling number to the group member. Since the P0C group has signed the high priority member, the low priority calling is unconditionally displayed. The number, while the CF checks that the number of the calling P0C terminal 1 must be displayed to the P0C terminal 2, but is not displayed to the P0C terminal 3.

Steps 95 to 98: When the CF unconditionally displays the number of the calling P0C terminal 1 to some of the called parties in the group, the CF will notify the P0C terminal 1 that the number has been displayed to some of the called by a notification message (for example, a NOTIFY message). The user is called, and can indicate in the message that the calling number information is displayed to the P0C terminal 2 as needed. Steps 99 to 912: Steps 95 and 99 are performed in sequence, and may be performed simultaneously. The CF will initiate a call to the POC terminal 2, and the message carries P-Asserted-Identity, and the POC terminal 2 requests the server to successfully return to the session. In response, the response message contains the following information:

 P- Asserted- Identity: "PoC User A" <sip :PoC-UserA@networkA. net>

 Step 913: Steps 95 and 913 are in no order, and may be performed simultaneously. The CF will initiate a call to the POC terminal 3, the message will not carry P-Asserted-Identity, or the message carries the P-Asserted- Identity header field at the same time. The privacy header field value is Id; the subsequent P-Asserted- Identity header field deletion work can be handled by the PF3 or the IMS (IP Multimedia Subsystem), and the P0C terminal 2 requests the server to respond successfully to the session response message. The information contained is as follows:

 P- Preferred- Identity: "PoC User A" <sip :PoC-UserA@networkA. net>

 The subsequent processing of the Privacy: Id is similar to the processing provided by the first embodiment of the second implementation provided by the present invention and will not be described in detail herein.

 It is the same as described in the first embodiment of the second scheme. In this scheme, in addition to notifying the calling user to display the calling number unconditionally to the called user through the subcribe/notify mechanism, the MESSAGE can also be passed. The mechanism implements the notification. At this time, since the unconditional calling number display is implemented only for the POC terminal 2, the CF only needs to send the MESSAGE message to the calling user for the POC terminal 2. In addition, after receiving the response message of the called P0C terminal 2, the indication information is added therein to indicate that the calling number information is unconditionally displayed for the called user, that is, the corresponding information is added in steps 911 and 912. Instructions. Of course, the corresponding notification can also be sent through other protocol messages.

 In addition, it should be noted that: If a group in the POC XDMS service subscribes to a group that is not a member of the group, the calling number will be displayed unconditionally, so that if the calling user is not a member of the group, The CF sends the calling number to each group member to be called.

 It can be seen that the second implementation provided by the present invention can implement the P0C in the case that the P0C caller does not want the P0C called party to display its number, according to the P0C called party must have the right to know the P0C caller. Call the unconditional display of the calling number. Moreover, the scheme does not make too many changes to existing basic group calls, and whether or not the caller's decision is displayed on the CF. The two implementations provided by the present invention can be simultaneously applied to a communication system having a hidden calling number service, and a corresponding specific implementation will be described below.

 After the P0C terminal that has hidden the calling number initiates the call, the call request message is sent to the CF, and the CF determines the subsequent processing according to the configured service attribute information of the primary and the called user, including:

 If it is determined according to the service attribute information that the calling party is required to provide the calling number information by using the negotiation mode, the corresponding negotiation process is performed to obtain the calling number information.

If it is determined according to the service attribute information that the calling number information needs to be displayed unconditionally, the calling party number information of the calling user is directly provided to the called user; If it is determined according to the service attribute information that the calling number information may not be displayed, the subsequent call processing process is directly continued.

 It should be noted that the negotiation mode and the unconditional display of the calling number information in the present invention can also be implemented on different network entities, for example, the called user's P0C server, the called P0C terminal, and the like. The specific implementation of the two processing modes is described in the foregoing, and will not be described in detail herein.

 In addition, if it is determined according to the service attribute information that the negotiation mode and the unconditional display are simultaneously matched, the corresponding processing mode may be selected according to the predetermined rule. For example, if the priority of the unconditional display is higher than the negotiation mode display, then the unconditional selection is selected at this time. How the display is handled.

 In summary, the two implementations provided by the present invention enable the calling party that uses the hidden calling number service to determine whether to provide the calling number information to the called user according to actual needs during the communication process, thereby ensuring that the calling number information is provided to the called user. The flexibility of network operations.

 The present invention also provides an apparatus for processing a calling number display in a communication process, and the specific implementation structure thereof is as shown in FIG. 10, including determining a calling number hiding processing unit and providing a calling number processing unit, where:

 (1) Determine the calling number hiding processing unit

 (2) Provide calling number processing unit

 The unit is configured to determine, according to the configured service attribute information of the user, whether to provide the called number information to the called user, and the providing the calling number processing unit includes the following specific When the terminal device of the called user receives the session request sent by the calling user, it is determined that the calling party number information needs to be provided through negotiation according to the configured service attribute information of the user;

 and / or,

 When receiving the session request sent by the calling user, the POC server determines, according to the configured service attribute information of the calling and called user, that the calling number information is required to be provided through negotiation.

 In addition, the process of providing the calling number processing unit in the present invention may further include: when the terminal device of the called user receives the session request sent by the calling user, determining, according to the received external operation control information, that the negotiation needs to be performed. The method requires that the calling number information be provided;

 The providing calling number processing unit may further comprise: a negotiation providing a calling number processing unit: when it is determined that the calling number information is required to be provided by means of negotiation, the P0C server of the called user or the called user sends a negotiation and provides The iff request of the calling number information; when the P0C server of the calling user or the calling user receives the request for negotiating the calling party number information, the P0C server of the calling user or the calling user according to the configured service attribute information or The calling user rejects the request or provides the calling number information to the called user based on the received external operation information. The negotiation provides that the calling number processing unit is set in the user terminal or the P0C server. Moreover, the specific negotiation processing method has been described above, and therefore will not be described in detail herein.

The device of the present invention may further include a service attribute configuration unit and a service attribute query unit, where: a service attribute configuration unit, configured to configure user service attribute information on a POC server, an extensible markup language file management server, a POC XDMS, or a P0C terminal device;
