Description
Technical Field
The present invention relates to an IMS (IP Multimedia Subsystem), and more particularly, to a method and system for an MSC (mobile switching center) to obtain ICP (IMS control point) information.
Background
IMS is an IP-based network architecture proposed by 3GPP (3rd Generation Partnership Project), which constructs an open and flexible service environment, supports multimedia applications, and can provide rich multimedia services to users.
In the IMS service system, the control layer and the service layer are separated, the control layer does not provide specific services, and only provides necessary functions of triggering, routing, charging and the like for the service layer.
The service triggering and control functions in the control layer are performed by a CSCF (Call Session control function). CSCFs are divided into three types: P-CSCF (Proxy-Call Session Control Function), I-CSCF (Interrogating-Call Session Control Function), and S-CSCF (Serving-Call Session Control Function); where the S-CSCF is responsible for the main responsibility and the I-CSCF is optional. In addition, there are some auxiliary network elements in the IMS service architecture, such as IBCF (IMS boundary control function) and ATCF (access transfer control function).
The business layer is composed of a series of AS (Application Server) and provides specific business services. The AS may be a separate entity or may reside in the S-CSCF. And the S-CSCF controls service triggering according to the subscription information of the user, calls the service on the AS and realizes the service function.
The end-to-end device in the session is called UE (User Equipment) and is responsible for interaction with the User. There are UEs with various ways to access a mobile network, such as accessing the mobile network through the PS (Packet Switch) domain of a 3GPP mobile network, accessing the mobile network through the PS domain of a non-3 GPP mobile network (such as a CDMA (code division multiple access) 1X or Wimax (worldwide interoperability for microwave access) network), and even accessing the mobile network through the CS (Circuit Switch) domain of the mobile network. The mobile network includes a base station subsystem and a core network, and network elements of the core network may be SGSN (serving GPRS support node), GGSN (gateway GPRS support node), MME (mobility management entity), MSC, PCF (packet control function), PDSN (packet data serving node), or the like. In order to realize the interaction between the UE and the IMS network in the CS domain, in some cases, the MSC is required to obtain the ICP information, and the ICP may be an entity having an IMS signaling control function, such AS a P-CSCF, an I-CSCF, an IBCF, an ATCF, or an AS, or even an MSC having an IMS signaling function.
Fig. 1 is a flowchart of an MSC acquiring ICP information in the prior art, where the acquiring process includes:
step 101: the UE initiates an Attach Request to the mobile network, for example, sends an Attach Request (Attach Request) message to a base station subsystem serving itself; the Base station subsystem may be a Base Station System (BSS) or a Radio Network Controller (RNC).
Step 102: the base station subsystem sends an attach request message to the MSC.
Step 103: after receiving the Attach request message, the MSC allows the UE to Attach and use the mobile network, and then sends an Attach allowed message, such as an Attach Accept (Attach Accept) message, to the UE, where the Attach allowed message is routed through the base station subsystem.
Step 104: the base station subsystem sends an attach allowed message to the UE.
Step 105: after the MSC allows the UE to attach and use the mobile network, it initiates a registration request to the UE 'S home IMS network, such as sending a registration (Register) message to an S-CSCF in the UE' S home IMS network, where the registration message belongs to IMS signaling.
Step 106: the S-CSCF allows the UE to access the IMS network and then returns a registration response to the MSC, such as sending a "200 OK" message, which pertains to IMS signaling.
Step 107: the UE initiates a registration request to a home IMS network of the UE through an access service and a P-CSCF provided by a PS domain, for example, a Register message is sent to the P-CSCF so as to use a service provided by the IMS network; wherein the Register message belongs to IMS signalling.
The following step is the case where ICP is not on AS.
If the ICP is between the P-CSCF and the S-CSCF, as on IBCF, then this includes:
step 108 a: the P-CSCF, upon receiving the registration request, selects an ICP serving the UE and forwards the registration request to the ICP.
Step 109 a: after receiving the registration request, the ICP sends another registration request to the S-CSCF, where the another registration request carries ICP information, and the ICP information may be information for directly positioning the ICP, such as a number, an address, or an identifier of the ICP, or information for indirectly positioning the ICP, such as an index of the ICP, or any combination of the above information.
Step 110 a: the S-CSCF allows the UE to access the IMS network and use services provided by the IMS network, and then returns a registration response, such as sending a "200 OK" message, which pertains to IMS signaling.
Step 111 a: the register response arrives at the ICP, which forwards the register response to the P-CSCF.
If the ICP is on the P-CSCF, then steps 108a-111a are simplified to:
and after receiving the registration request, the P-CSCF sends another registration request to the S-CSCF, wherein the other registration request carries ICP information.
The S-CSCF allows the UE to access the IMS network and use services provided by the IMS network, and then returns a registration response to the P-CSCF, such as sending a "200 OK" message, which pertains to IMS signaling.
If the ICP is on the S-CSCF, then steps 108a-111a are simplified to:
and after receiving the registration request, the P-CSCF forwards the registration request to the S-CSCF.
The S-CSCF allows the UE to access the IMS network and use services provided by the IMS network, and then returns a registration response to the P-CSCF, such as sending a "200 OK" message, which pertains to IMS signaling.
The following steps are for the case of ICP on AS.
Step 108 b: and after receiving the registration request, the P-CSCF forwards the registration request to the S-CSCF.
Step 109 b: the S-CSCF allows the UE to access the IMS network and use services provided by the IMS network, and then returns a registration response to the P-CSCF, such as sending a "200 OK" message, which pertains to IMS signaling.
Step 110 b: the S-CSCF forwards the registration request to the ICP.
Step 111 b: after receiving the registration request, the ICP returns a registration response to the S-CSCF, where the registration response carries ICP information, and the ICP information may be information for directly locating the ICP, such as a number, an address, or an identifier of the ICP, or information for indirectly locating the ICP, such as an index of the ICP, or any combination of the above information.
The following steps are the common steps following the two cases.
Step 112: after receiving the registration response of step 111a or 109b, the P-CSCF forwards the registration response to the UE.
Step 113: after obtaining the ICP information, the S-CSCF notifies the obtained ICP information to the MSC, for example, sends a Notify message to the MSC, where the Notify message carries the obtained ICP information, and belongs to the IMS signaling.
As can be seen from the above procedure, in the prior art, the MSC must support the IMS signaling and complete the registration process instead of the UE to obtain the ICP information; if the MSC does not support IMS signaling, a new interface and protocol need to be added to enable the MSC to perform message interaction with the S-CSCF in order to apply the procedure shown in fig. 1, so the application scenario of the procedure is limited.
Disclosure of Invention
In view of the above, the main objective of the present invention is to provide a method and a system for an MSC to obtain ICP information, so that the MSC can obtain ICP information without adding a new interface and a new protocol.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:

Detailed Description
The present invention is further illustrated by the following examples.
Example one
Fig. 2 is a flowchart of an MSC obtaining ICP information according to a first embodiment of the present invention, and describes a process in which, after a UE initiates a call in a CS domain, the MSC anchors the CS call in an IMS domain, where the process includes:
step 201: the UE initiates a registration request, such as sending a Register message, to the IMS network over the PS domain.
Step 202: the registration request is routed through the P-CSCF, which forwards the registration request to the ICP.
Step 203: the ICP forwards another register request to the S-CSCF, where the another register request carries ICP information, and the ICP information may be information for directly locating the ICP, such as a number, an address, or an identifier of the ICP, or information for indirectly locating the ICP, such as an index of the ICP, or any combination of the above information.
Step 204: the S-CSCF allows the UE to access the IMS network and then returns a registration response, such as sending a "200 OK" message.
Step 205: and after receiving the registration response, the ICP forwards the registration response to the P-CSCF.
Step 206: and after receiving the registration response, the P-CSCF forwards the registration response to the UE.
Step 202-; the MSC may be an MSC to which the UE attaches (i.e., the MSC shown in fig. 2), or may be another MSC. If the ICP is on the MSC to which the UE is attached, there is no change in step 202-.
If the ICP is at the P-CSCF, then step 202 and 206 are simplified to:
after receiving the register request, the P-CSCF forwards another register request to the S-CSCF, wherein the another register request carries ICP information;
the S-CSCF allows the UE to access the IMS network and then returns a registration response, such as sending a "200 OK" message;
and after receiving the registration response, the P-CSCF forwards the registration response to the UE.
If the ICP is at the S-CSCF, then step 202 and 206 are simplified to:
the registration request passes through the P-CSCF, and the P-CSCF forwards the registration request to the S-CSCF;
the S-CSCF allows the UE to access the IMS network, and then returns a registration response;
and after receiving the registration response, the P-CSCF forwards the registration response to the UE.
The above steps belong to an IMS registration procedure, and there may be other IMS message interaction procedures between the UE and the IMS network, for example, when an Invite message of an IMS call request passes through an ICP, the ICP (ICP is not on the S-CSCF) may also carry ICP information in the Invite message forwarded to the S-CSCF.
Step 207: and the S-CSCF forwards the registration request carrying the ICP information to the AS according to the subscription information of the UE.
In the IMS calling process, the S-CSCF forwards an Invite message carrying ICP information to the AS.
Step 208: the AS returns a register response to the S-CSCF, such AS sending a "200 OK" message.
Step 209: the AS sends a notification message carrying ICP information to the SGSN, such AS an Insert Subscriber Data (Insert Subscriber Data) message carrying ICP information.
Step 210: the UE sends a call request, such as a Setup message, to the MSC in the CS domain.
Step 211: upon receiving the call Request, the MSC queries the SGSC for ICP information, such as sending an Identity Request message.
Step 212: the SGSN returns a response carrying the ICP information, for example, sends an identity response (identity response) message carrying the ICP information.
To this end, the MSC obtains ICP information.
Step 213: the MSC sends a call request to the ICP according to the ICP information, for example, when the MSC does not support the IMS signaling, the MSC sends an IAM (Initial Address Message); or when the MSC supports IMS signaling, an Invite message is sent.
Step 214: the ICP continues with the subsequent IMS call procedure.
Step 215: the ICP receives the called answer and sends a call response, such as an ANM (answer message) or a "200 OK" message, to the MSC.
Step 216: the MSC sends a call response, such as a Connect message, to the UE.
If the ICP is on the AS, the ICP information sent by the AS to the SGSN in step 209 is generated by the AS and not forwarded by the S-CSCF, and step 202-:
the registration request passes through the P-CSCF, and the P-CSCF forwards the registration request to the S-CSCF;
the S-CSCF allows the UE to access the IMS network and then returns a registration response, such as sending a "200 OK" message;
after receiving the registration response, the P-CSCF forwards the registration response to the UE;
the S-CSCF forwards a registration request to the AS according to the subscription information of the UE;
the AS returns a register response to the S-CSCF, such AS sending a "200 OK" message.
AS can be seen from the above variation of step 202-208, there is no ICP information in the forwarded registration request or Invite message when the ICP is on the AS.
Example two
Fig. 3 is a flowchart of an MSC acquiring ICP information according to a second embodiment of the present invention, and describes a process in which a UE in a CS domain session is transferred to a PS domain, and the MSC notifies the ICP to start transferring, where the process includes:
step 301-308: similar to step 201-208 in fig. 2, the description is omitted here.
Step 309: the AS sends an update message carrying the ICP information to an HSS (home subscriber Server), for example, sends an Sh-push (Sh-push) message carrying the ICP information.
If the ICP is on the AS, the ICP information is generated by the AS; otherwise, the ICP information is forwarded by the S-CSCF to the AS.
Step 310: the HSS sends a notification message carrying ICP information to the SGSN, such as an Insert Subscriber Data message carrying ICP information.
Step 309-310 may also be replaced by step 209 in fig. 2.
Step 311: the UE has a session in the CS domain, for example, the UE initiates a call in the CS domain or receives a call in the CS domain but has a session, during the session, the base station subsystem determines to switch the CS domain session of the UE to the PS domain, and then sends a Handover Request to the MSC, and triggers a Handover procedure from the CS domain to the PS domain, for example, sends a Handover Request message or a Relocation Request message.
Step 312: after receiving the handover Request, the MSC queries the SGSC for ICP information, such as sending an Identity Request message.
Step 313: the SGSN returns a response carrying the ICP information, for example, sending an identify response message carrying the ICP information.
To this end, the MSC obtains ICP information.
Step 314: the MSC sends a transfer request to the ICP according to the ICP information, for example, when the MSC does not support IMS signaling, an IAM message is sent; or when the MSC supports IMS signaling, an Invite message is sent.
Step 315: the ICP returns a transfer response to the MSC, such as sending a "200 OK" message.
Step 316: the MSC informs the UE to switch to the PS domain, e.g. sending a Handover Command message.
Step 317: concurrently with step 315, the ICP initiates a process of re-establishing a media connection between the ICP-controlled media gateway and the remote UE, such AS sending a re Invite message to the remote UE, or sending an Invite message to the AS and sending a re Invite message by the AS to the remote UE.
Step 318: after step 316, the UE modulates to the PS domain and accesses the IMS network through the PS domain.
Step 319: the UE initiates a transfer request in the PS domain, such as sending an Invite message or a reInvite message.
Step 320: after receiving the transfer request, the ICP returns a transfer response, such as sending a "200 OK" message, to the UE.
Step 321: the ICP establishes media connection between a media gateway controlled by the ICP and the UE according to a transfer request initiated by the UE, and enables the UE to continue conversation with the remote UE in the PS domain through the bridging effect of the ICP.
The process after step 313 in the second embodiment can also have other implementation schemes, and the second embodiment only illustrates the implementation scheme of one of the cases, but the process after step 313 does not affect the process between steps 301 and 313.
In order to implement the method, the embodiment of the invention also provides a system for acquiring the ICP information by the MSC. As shown in fig. 4, the system includes: AS, SGSN and MSC; wherein,
