Description
Technical Field
The present invention relates to a connection state notification technology, and more particularly, to a method for notifying a called connection state to a calling terminal in a CDMA 2000 circuit domain and a terminal using the same.
Background
In current communication networks, during a connection after a calling subscriber dials a called terminal number, the calling subscriber may hear a ring back tone and alert tones such as a blank tone, a busy tone, a congestion tone, etc. from the communication network. The communication network plays the ring back tone and the prompt tone to the calling terminal, and the aim is to inform the calling user of the connection state of the called terminal in the connection process, namely the called connection state, for example, the calling user can know that the dialed called terminal number does not exist by receiving the null tone, the called terminal can know the current ringing or busy by receiving the ring back tone or the busy tone, and the called side network congestion can be known by receiving the congestion tone. Therefore, the ring back tone and various alert tones are collectively referred to as continuation tones hereinafter, but it should be noted that the called connection state referred to in this application does not include only the state represented by the existing continuation tone, but also summarizes all the states of the called terminal during the connection process, including states customized by the called terminal, such as personalized connection states like "in a meeting, later replying" and the like.
Fig. 1 is a schematic diagram of a prior art method for informing a calling terminal of a called connection status, in which a solid line represents a signaling link and a dotted line represents a speech path. Wherein the various continuation tones are stored in the playback entity.
The continuous state obtaining entity is used for obtaining the called continuous state and sending a continuous sound playing instruction to the sound playing entity through the signaling link.
And after the playback entity receives the continuation tone playing instruction from the continuation state acquisition entity, playing the corresponding continuation tone to the calling terminal through the speech path.
It should be noted that, although the connection status acquiring entity and the playback entity are logically independent from each other, physically, these two entities may be disposed in the same network device, in other words, the same network device serves as both the connection status acquiring entity and the playback entity, in this case, from the external view, the operation of sending the connection audio playback instruction is an internal operation of the network device.
In the following, how to inform the called connection status to the calling terminal in the prior art is described in detail in conjunction with the existing communication network.
In a conventional mobile network before control and bearer separation, a Mobile Switching Center (MSC) is used as a connection state acquisition entity and a playback entity, wherein common network application scenarios and implementation manners include:
(1) the calling side MSC is used as a connection state acquisition entity and a sound reproduction entity at the same time, for example, when the calling side MSC learns that the called terminal number does not exist, the calling side MSC directly plays a null tone to the calling terminal through a speech path;
(2) the called side MSC is used as a connection state acquisition entity and a sound playing entity at the same time, for example, when the called side MSC learns that the called terminal rings, the called terminal is busy or the called side network is congested, the called side MSC directly plays the corresponding ring back tone, busy tone or congestion tone to the calling terminal through the speech path.
(3) The called side MSC is used as a connection state acquisition entity, the calling side MSC is used as a sound reproduction entity, for example, when the called side MSC learns that the connection of the called terminal is failed, if paging does not respond, the called side MSC sends a failure reason and a sound reproduction instruction to the calling side MSC through a signaling link, and the calling side MSC plays a corresponding failure sound to the calling terminal through a speech path.
In a mobile network with separated control and bearer based on soft switch, a mobile switching center emulation (MSCe) is used as a connection state acquisition entity, and a Media Gateway (MGW) is used as a playback entity, wherein common network application scenarios and implementation manners include:
(1) calling side MSCe is used as the connection state obtaining entity, calling side MGW is used as the playback entity, for example, when the calling side MSCe knows that the called terminal number does not exist, the calling side MSCe sends a null tone playing instruction to the calling side MGW through the signaling link, and the calling side MGW plays the null tone to the calling terminal through the speech path;
(2) the called side MSCe is used as a connection state obtaining entity, the called side MGW is used as a sound reproduction entity, for example, when the called side MSCe learns the ringing or busy of the called terminal, a ring back tone playing instruction or a busy sound playing instruction is sent to the called side MGW through a signaling link, and the called side MGW plays the ring back tone or the busy sound to the calling terminal through a speech path;
(3) the called side MSCe is used as the continuous state obtaining entity, the calling side MGW is used as the playback entity, for example, when the called side MSCe learns the network congestion of the called side, the called side MSCe sends a congestion tone playing instruction to the calling side MSCe through the signaling link, the calling side MSCe sends the congestion tone playing instruction to the calling side MGW according to the received instruction, and the calling side MGW plays the congestion tone to the calling terminal through the speech path.
The MSC and MSCe are collectively referred to herein as the mobile switching office.
In addition, for the fixed network and the mobile network supporting the personalized ring back tone service, the customized ring back tone is usually stored in a specific ring back tone server, when the continuing state acquiring entity learns the ringing of the called terminal, the continuing state acquiring entity sends a ring back tone playing instruction to the ring back tone server through a signaling link, and the ring back tone server plays the customized ring back tone to the calling terminal through a telephone line.
It can be seen that, in each stage of communication network evolution, the method for notifying the called connection status to the calling terminal is based on the architecture shown in fig. 1, that is, the called connection status can be notified to the calling terminal in an in-band manner only by means of a playback entity located in the communication network, and this architecture brings the following problems: because the playback entity needs to play the continuation tone to the calling terminal through the speech path, no matter whether the speech path is finally established between the calling terminal and the called terminal, the speech path must be established between the playback entity and the calling terminal for playing the continuation tone, and the result necessarily causes the waste of speech path resources, and the waste of the speech path resources is particularly serious when the playback entity is positioned in the called side network.

step 505: the calling side BS sends an air interface message carrying the called connection state information to the calling terminal through the signaling link.
The method is mainly used for the situation that the called terminal acquires the called connection state, for example, when the called terminal generates the connection state according to the indication of the called user or local configuration, the called terminal transmits the called connection state information representing the corresponding connection state to the calling terminal through a signaling link.
Fig. 6 is a schematic diagram of a fourth application scenario of the present principles, which occurs in a mobile network with separated control and bearer based on soft switch, wherein the connection state acquiring entity is a calling side MSCe, and the calling side MSCe notifies the calling terminal of the called connection state through a calling side BS.

It should be noted that the present invention can also be applied in a hybrid networking scenario, for example, the calling side network is a traditional mobile network before the control and bearer are separated, and the called side network is a mobile network based on the control and bearer separation of the soft switch, in this scenario, the calling side MSC and the called side MSCe can perform the signaling protocol conversion through one signaling gateway, and details are not described here.
The above-mentioned a interface refers to an interface between the BS and the MSC or between the BS and the MSCe; the inter-exchange message refers to a message between mobile switching offices, and specifically includes a message between MSC, a message between MSCe and MSCe, or a message between MSC and MSCe.
In the present invention, a method for notifying a called connection status to a calling terminal is introduced in combination with a specific application scenario in an existing communication network, and it should be noted that the method does not specifically limit an interoffice message, an a interface message, and an air interface message used for carrying called connection status information, nor specifically limit called connection status information carried by the interoffice message, the a interface message, and the air interface message.
The interoffice message, the a interface message, and the air interface message for carrying the called connection state information may be existing messages, for example: the interoffice message may be an existing Address Complete Message (ACM), an answer message (ANM), a call progress message (CPG), a connection message (CON), and the like; the interface a message may be an existing Flash With Information (FWI) or the like; the air interface message may be an existing FWI message, etc.
The interoffice message, the a interface message, and the air interface message for carrying the called connection state information may also be newly added messages, and these newly added interoffice message, the a interface message, and the air interface message should respectively conform to the basic format requirements of the Integrated Services Digital Network (ISDN) user part (ISUP) protocol or/and the SIP (Session Initiation protocol 1) message, the international organization for standardization (ISO) protocol, and the air interface protocol.
The called connection state information carried by the interoffice message, the a interface message, and the air interface message may be contained in an existing cell, for example: the called connection state Information carried in the interoffice message may be contained in User-to-User Information (UUI) in the ISUP protocol or contained in the ISUP message package of the SIP; the called connection state Information carried in the a interface message may be Mobile Station Information Records (MSIRs) in the ISO protocol; the called connection state Information carried in the air interface message may be Information Records (IR) in an air interface protocol.
The called connection state information carried by the interoffice message, the a interface message and the air interface message may also be included in the newly added cells, and these newly added cells carried by the interoffice message, the a interface message and the air interface message may be simplification of the existing cells, or may define the format with reference to the existing cells.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings by way of examples.
The first embodiment is as follows: fig. 9 is a flowchart of notifying a called connection state to a calling terminal in the first embodiment of the present invention, and this embodiment specifically illustrates how, in a fifth application scenario of the present invention, a called side MSCe notifies the calling terminal of the connection state after knowing that a current state of the called terminal is ringing. The process of notifying the called connection status to the calling terminal in this embodiment includes:
step 901: a called side MSCe sends 180 messages indicating the ringing of a called terminal to a calling side MSCe, the 180 messages carry ACM messages packaged according to ISUP, the ACM messages contain User-to-User message indicator (User-to-User indicator) and UUI cells packaged by the called side MSCe according to the current called connection state, wherein the User-to-User message indicator indicates that the ACM messages contain UUI cells, and the UUI cells contain information which can be recognized by the calling terminal and indicates the ringing of the called terminal, such as digital information or text information corresponding to 'the ringing of the called terminal';
step 902: the calling side MSCe returns a temporary response acknowledgement (PRACK) message in response to the 180 message in step 901 to the called side MSCe;
step 903: the called side MSCe returns a 200 OK message in response to the PRACK message in step 902 to the calling side MSCe;
step 904: the calling side MSCe sends a FWI message carrying the UUI information element in the step 901 to the calling side BS, wherein the UUI information element can be added in the MSIR field of the FWI message;
step 905: the calling side BS sends the FWI message in step 904 to the calling terminal, and the calling terminal analyzes the received FWI message to know that the current called connection state of the called terminal is ringing. At this point, the called terminal rings, and the calling terminal is informed of the continuing state.
After the calling terminal learns that the current called connection state of the called terminal is ringing, the calling terminal can further combine with the self setting to present the connection state as a mode which can be identified by the calling user, for example, generating a ring tone prompt or displaying information such as characters, pictures, videos and the like on a screen.
However, after step 903, the following steps 904 'to 905' may be executed without executing the above steps 904 to 905, and the steps 904 'to 905' are not shown in the figure.
Step 904': the calling side MSCe constructs a short message by using the UUI cell in step 901 as data, and carries the short message in an Application data delivery service delivery message (ADDS delivery) message to send to the calling side BS;
step 905': the calling side BS transmits the short message in step 904' to the calling terminal through a traffic channel. The called terminal rings and informs the calling terminal of the connection state, the calling terminal can directly display the received short message on the screen, or after identifying the content of the short message, the connection state is presented as a mode which can be identified by the calling user according to the connection state indicated by the content and the self setting, for example, a ring tone prompt is generated or information such as characters, pictures, videos and the like is displayed on the screen.
Example two: fig. 10 is a flowchart of notifying a called connection state to a calling terminal in the second embodiment of the present invention, and this embodiment specifically illustrates how, in a fifth application scenario of the present invention, a called side MSCe notifies the calling terminal of the connection state after knowing that a current state of the called terminal is called off-hook. The process of notifying the called connection status to the calling terminal in this embodiment includes:
step 1001: the called side MSCe sends 200 OK information indicating called user off-hook to the calling side MSCe, the 200 OK information carries ANM information packaged according to ISUP, the ANM information comprises user-to-user information indicator and UUI cell packaged by the called side MSCe according to the current called connection state, wherein the user-to-user information indicator indicates that the ACM information contains UUI cell, and the UUI cell comprises information which can be identified by the calling terminal and indicates called user off-hook, such as digital information or text information corresponding to the called user off-hook;
step 1002: the calling side MSCe returns an Acknowledgement (ACK) message in response to the 200 OK message in step 1001 to the called side MSCe;
step 1003: the calling side MSCe sends a FWI message carrying the UUI information element in the step 1001 to the calling side BS, wherein the UUI message can be added in the MSIR field of the FWI message;
step 1004: the calling side BS sends the FWI message in step 1003 to the calling terminal, and the calling terminal analyzes the received FWI message, so that the current called connection state of the called terminal can be known to be off-hook. At this point, the called terminal is notified of the connection status of off-hook.
After the calling terminal knows that the current called connection state of the called terminal is off-hook, the calling terminal can further combine with the self setting to express the connection state into a mode which can be identified by the calling user, for example, generating a ring tone prompt or displaying information such as characters, pictures, videos and the like on a screen.
However, after step 1002, the following steps 1003 'to 1004' may be executed without executing the above steps 1003 to 1004, and steps 1003 'to 1004' are not shown in the figure.
Step 1003': the calling side MSCe takes the UUI cell in the step 1001 as data to construct a short message, and carries the short message in an ADDS Deliver message to be sent to the calling side BS;
step 1004': the calling BS sends the short message in step 1003' to the calling terminal through a traffic channel. The called terminal is informed of the connection state of off-hook, and the calling terminal can directly display the received short message on the screen or combine with the self-setting according to the connection state indicated by the content after identifying the content of the short message, and present the connection state as a mode which can be identified by the calling user, for example, generating a ring tone prompt or displaying information such as characters, pictures, videos and the like on the screen.
Example three: fig. 11 is a flowchart of notifying a called connection status to a calling terminal in a third embodiment of the present invention, where the third application scenario is based on the present invention, that is, the called terminal is used as a connection status acquisition entity.
For example, when the called party is currently in a meeting and is inconvenient to answer the call, the called party sets the current connection state of the called terminal to be 'in the meeting and later replying', and when the calling terminal calls the called terminal, the called terminal knows that the current connection state of the called terminal is 'in the meeting and later replying' and informs the calling terminal of the state through a signaling link. Specifically, the process of notifying the called connection status to the calling terminal in this embodiment includes:
step 1101: the called terminal sends FWI information to the called side BS, the FWI information carries the call connection state information of the current terminal, such as 'in meeting, later reply' corresponding digital information or text information;
step 1102: the called side BS sends the FWI message in the step 1101 to a called side MSC;
step 1103: the called side MSC sends CPG message to the calling side MSC, the CPG message contains user-to-user message indicator and UUI cell packed by the called side MSC according to the called connection state, wherein the user-to-user message indicator indicates that the CPG message contains UUI cell, the UUI cell contains call connection state information carried by the FWI message in the step 1102;
step 1104: the calling side MSC sends a FWI message carrying the UUI information element in step 1103 to the calling side BS, wherein the UUI information element can be added in the MSIR field of the FWI message;
step 1105: the calling BS sends the FWI message in step 1104 to the calling terminal, and the calling terminal analyzes the received FWI message to know that the current called connection status of the called terminal is "in meeting, and replies later". To this end, the "meeting is being opened and the" connection state notification is replied to the calling terminal.
After the calling terminal knows that the current called connection state of the called terminal is 'in meeting and replying later', the calling terminal can further express the connection state into a mode which can be identified by the calling user by combining the self setting, for example, generating a ring tone prompt or displaying information such as characters, pictures, videos and the like on a screen.
However, after step 1103, the following steps 1104 'to 1105' may be executed without executing the above-described steps 1104 to 1105, and the steps 1104 'to 1105' are not shown in the figure.
Step 1104': the calling side MSC takes the UUI cell in step 1103 as data to construct a short message, and carries the short message in an ADDS delivery message to be sent to the calling side BS;
step 1105': the calling side BS transmits the short message in step 1104' to the calling terminal through a traffic channel. So far, the "meeting is being opened and the connection state is replied to" the calling terminal, the calling terminal can directly display the received short message on the screen, or after the content of the short message is identified, the connection state is presented as a mode which can be identified by the calling user according to the connection state indicated by the content and the self setting, for example, a ring tone prompt is generated or information such as characters, pictures, videos and the like is displayed on the screen.
