Description

Method and device for routing messages in traditional network based on SIP protocol

technical field

The invention relates to the field of network technology, in particular to a method and equipment for routing messages based on the SIP protocol in a traditional network.

Background technique

SIP (Session Initiation Protocol, Session Initiation Protocol) message is a message transmission format based on TCP (Transmission Control Protocol, Transmission Control Protocol)/IP (Internet Protocol, Internet Protocol) protocol commonly used on the Internet. The most widely used is the instant message service. Since the network generally does not store and forward this type of message, the delay in message transmission is relatively small, so it is called instant message. SIMPLE IM is an instant message format defined by OMA (Open Mobile Alliance, Open Mobile Alliance), including session-independent message modes (Page mode, Large message mode) and session-based message mode (session based message). Fan adopted a form of instant messaging application. Wherein, Page mode is a message transmission mode based on SIP MESSAGE, and Large message mode and session basedmessage mode are both based on other SIP protocols such as MSRP (Message Session Relay Protocol, message session relay protocol) message transmission mode. 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project) also defines a message format carried in SIP messages for transmission, which is mainly used in IMS (IP multimedia subsystem, IP multimedia system). In addition, the current popular subject of OMA, CPM (Converged IP Messaging, converged IP messaging services), is also discussing a message format based on the SIP protocol - CPM messages. In the application of the fusion of various messaging services, the same user experience can be maintained when using different messaging services. With the rise and development of IMS-based access technologies, how to realize the intercommunication between IP-based messages and other types of message services, including OMA SIMPLE IM instant messages and SMS (Short Message Service) defined by 3GPP /EMS (Enhanced Message Service, Enhanced Short Message Service) business intercommunication, and CPM message and non-CPM message (such as between SMS/EMS defined by 3GPP) etc.; in realizing SIP MESSAGE and other types of On the basis of message exchange, how to maintain the consistency of user experience, reduce the impact on the existing network, and reuse the routing function and service processing function of the existing network is also a common concern of operators and a goal of the 3GPP standardization organization.

Since the EMS defined by 3GPP belongs to the enhanced type of SMS, for the sake of simplicity, the short message described below includes both SMS and EMS message services.

Figure 1 is the current network framework for implementing traditional short message services using IP terminals, in which SME (ShortMessage Entity, short message entity), SM-SC (Short Message-Service Center, short message service center), SMS-GMSC (Short Message Service Gateway Mobile SwitchingCenter, Short Message Mobile Switching Center Gateway)/SMS-IWMSC (Short MessageService-InterWorking Mobile Switching Center, Short Message Interworking Mobile Switching Center), HSS (Home subscriber server, home subscriber server), CGF (Charging GatewayFunction, billing Gateway function)/CDF (Charge Distribution Function, charging collection function) and OCS (Online Charging System, online charging system) are the functional entities of the existing mobile network to realize SMS services. Among them, SM-SC is used to store short messages; GMSC is used to query routing information from the HSS when receiving a called short message; SMS-IWMSC is used for authentication when a terminal sends a short message. Currently, the short message center used in the network is a collection of SM-SC, GMSC and SMS-IWMSC is a three-in-one device, and these three functional entities are not implemented as a separate physical device, so in the following, the short message center represents the three-in-one device of SM-SC, GMSC and SMS-IWMSC. HSS is used to store user's data information, including user's subscription service data and routing information, CGF/CDF is used to collect and process user's offline billing bill information, and then transfer it to the billing center, OCS is used to collect and process user The online billing bill information is then delivered to the billing center. In Figure 1, the IP message gateway realizes the communication between the IP client and the GMSC/SMS-IWMSC. The IP message gateway needs to carry out the IP network message protocol and the existing WCDMA/ Intercommunication at the transmission level or service level between the short message protocol of the GSM network (that is, the MAP protocol used between the IP message gateway and the GMSC/SMS-IWMSC), that is, the encapsulation/decapsulation or message format of the message carried by the SIP protocol convert.

In the existing 3GPP specifications, the intercommunication between the SIP protocol message based on the encapsulation of the traditional short message format and the traditional short message service at the transmission level and the service level between the instant message defined by SIMPLE IM or 3GPP and the traditional short message are proposed. Interworking services, in which the IP message gateway acts as a short message bearer interworking gateway between the IMS domain and the traditional CS/PS domain, performing authentication of SIP-based messages and traditional network message interworking services, and encapsulation/decapsulation or conversion of message formats and store-and-forward functionality for messages. Here, the IP messaging gateway provides services to the user through the user's third-party registration.

According to the above network architecture, the third-party registration process for traditional message service and SIP message interworking is shown in Figure 2, and the specific steps are as follows:

In step s201, the UE establishes an IP connection.

In step s202, the UE registers with the S-CSCF through the IMS registration process.

Step s203, the S-CSCF checks the initial filtering rules obtained from the HSS during the IMS registration process.

Step s204, after the successful IMS registration, the S-CSCF notifies the interworking server of the registration status of the user based on the initial filter rule.

Step s205, the interworking server returns a success response to the S-CSCF.

Step s206, the interworking server sends a registration request to the HSS.

Step s207 , the HSS stores the received information when needed, and uses it to notify the UE of becoming reachable in the IMS domain through an alarm message when the message waiting bit is set.

Step s208 , after the registration is successfully completed, the HSS checks whether the message waiting bit is not set, and whether an alarm procedure needs to be initiated.

According to the above-mentioned network architecture, the process of intercommunication between the traditional message service and the instant message service layer defined by SIMPLE IM or 3GPP in IMS-MO (message initiation in the IMS domain) is shown in Figure 3, and the specific steps are as follows:

Step s301, through the IMS registration process, the UE registers with the S-CSCF. For simplicity, I-CSCF and P-CSCF are not marked here.

In step s302, the UE sends an instant message to the S-CSCF using a suitable SIP method.

In step s303, the S-CSCF forwards the instant message to the IP messaging gateway based on iFC (initial Filtering Criteria, initial filtering rule).

Step s304, the IP message gateway decides whether to perform intercommunication at the service level by checking information such as the SIP header, operator policy, or whether the instant message can be routed by the called IMS. If it is decided to perform intercommunication at the service level, the IP message gateway will Authorize. If the authorization fails, the IP message gateway returns a failure report to the UE; otherwise, the IP message gateway converts the instant message into a traditional short message, and routes the short message to the routing entity of the traditional network. If the length of the instant message is greater than a short message The length of the message, the IP message gateway splits the instant message into multiple pieces, converts them into short message format, and forwards the converted short message to the short message service center.

Step s305, if the authorization is successful, the IP message gateway sends a success response to the S-CSCF.

Step s306, the S-CSCF forwards the success response to the UE.

In step s307, the SMS-IWMSC forwards the short message to the short message service center.

Step s308, the short message service center returns the report to the SMS-IWMSC.

In step s309, the SMS-IWMSC forwards the report to the IP message gateway.

In step s310, the IP message gateway converts the received report into an appropriate IMS message format and forwards it to the S-CSCF. If the IP message gateway generates multiple SM messages in the fourth part, the IP message gateway needs to wait for the return of the last report, convert all the reports into a suitable IMS message format, and forward it to the S-CSCF.

In step s311, the S-CSCF sends the converted instant message to the UE.

Step s312, the UE sends a success response to the S-CSCF.

Step s313, the S-CSCF forwards the success response to the IP message gateway.

During the process of realizing the present invention, the inventors found at least the following problems in the prior art.

In the IMS-MO process of the prior art, the SIP message of the calling UE is converted into an SM message after passing through the IP-SM-GW. In order to ensure compatibility with the existing short message process, the converted SM will definitely be transmitted to the short message first. The service center SM-SC, and then the short message service center transmits it to the peer UE according to the existing MT procedure. If the UE sends a SIP message in encapsulated SM format (such as intercommunication at the transport level), then the message contains the address of the SMS center, and the IP-SM-GW directly obtains the SMS message containing the address of the SMS center after decapsulating it. Messages can be routed by the network side to the Short Message Service Center. However, when performing interworking at the service level, what the UE sends is a SIP message (such as a SIMPLE IM or CPM message) that does not encapsulate any SM message, and the IP-SM-GW cannot obtain the UE's short message service center address information, so even if it can perform For message conversion, the network side does not know which short message center to send the converted short message to, and the message cannot be routed subsequently. In the current CPM interworking framework of the OMA, such problems also exist in the process of intercommunicating CPM messages and non-CPM messages.

Detailed ways

In the embodiment of the present invention, a method for routing a message based on the SIP protocol in a traditional network is shown in Figure 4, comprising the following steps:

In step s401, the interworking server receives a message based on the SIP protocol, and acquires a corresponding short message service center address.

Specifically, the method for obtaining the address of the short message service center may be:

(1) The interworking server acquires the short message service center address corresponding to the user from the HSS according to the user information in the message.

(2) The interworking server acquires the corresponding short message service center address from the SIP-based message.

(3) The interworking server obtains the corresponding information of the user according to the association relationship between the user information obtained from the third-party registration message received by the S-CSCF and the short message service center address, and the user information in the message based on the SIP protocol. Short message service center address.

(4) The interworking server obtains the short message service center address corresponding to the user according to the correspondence between the locally configured user information and the corresponding short message service center address, and the user information in the SIP protocol-based message.

In step s402, the interworking server converts the SIP-based message into a short message, adds the obtained short message service center address to the short message, and sends it.

According to the short message service center address carried in the short message, the network side can carry out the subsequent routing processing of the short message, thereby realizing the routing of the message based on the SIP protocol in the traditional network after format conversion.

The different ways in which the intercommunication server obtains the address of the short message service center in the present invention will be described in detail below in conjunction with specific application scenarios.

In Embodiment 1 of the present invention, taking the acquisition method as follows: the intercommunication server obtains the address of the short message service center from the HSS as an example, a specific implementation of a method for routing a message based on the SIP protocol in a traditional network in the present invention is described.

In the prior art, the user's subscription data and information related to message routing, such as short message service centers, are stored on the HSS. The corresponding short message service center is assigned to the user, and the corresponding relationship is stored in the HSS. In the prior art, the interworking server (such as the IP message gateway) can download the user's subscription data from the HSS through the Sh interface to provide the user with interworking services; in addition, the interworking server can also download the subsequent routing of the message from the HSS through the interface Information (such as the address of MSC/SGSN, etc.). In this embodiment, when the interworking server receives a message based on the SIP protocol, it judges that the processing of the interworking service at the service level is to be performed, and then after the service authorization is successful, the short message service related to the user information carried in the message is obtained from the HSS. The address of the center. The interworking server can acquire the address of the short message service center according to the following principle: if the interworking server is located in the IMS network of the calling side, then based on the information (such as address information) of the calling user, the address of the short message service center related to the calling party is obtained. address; if the interworking server is located in the IMS network of the called side, then obtain the address of the short message service center related to the called party based on the called user information. After the interworking server converts the message based on the SIP protocol into a traditional short message, it adds the address of the obtained short message service center to the routing information of the converted short message, so that the network side can perform subsequent routing processing of the short message.

A specific scenario of the above process is shown in Figure 5, taking the processing of the IMS network on the calling side by the interworking server as an example, including the following steps:

Step s501, through the IMS registration process, the UE is registered with the S-CSCF.

Step s502, the UE sends a SIP message to the S-CSCF.

Step s503, the S-CSCF forwards the SIP message to the interworking server based on the iFC.

Step s504, the interworking server determines whether interworking at the service level is required by checking the SIP header, operator policy, or whether the SIP message can be routed by the called IMS. If it decides to perform intercommunication at the service level, the interworking server authorizes the service . If the authorization fails, the interworking server returns a failure report to the UE. The failure is irrelevant to the embodiment of the present invention and will not be introduced here.

In steps s505-s506, after the authorization is successful, the interworking server returns a success response to the UE.

Step s507, the interworking server checks that the received SIP message is a message format (such as SIMPLE IM/CPM message) that does not encapsulate any SM message, and obtains it from the HSS according to the calling user information (such as the public user ID) carried by the message header The address of the short message service center related to the caller.

Steps s508-s509, the interworking server converts the SIP message into a traditional short message, adds the short message service center address obtained in step s507 to the address information of the short message, and routes the short message to the traditional network routing entity SMS-IWMSC .

In step s510, the SMS-IWMSC forwards the message to the SMSC according to the address information of the SMSC carried in the short message.

Step s511, the short message service center returns the report to the SMS-IWMSC.

In step s512, the SMS-IWMSC forwards the report to the interworking server.

Step s513, the interworking server converts the received report into a proper SIP message format, and forwards it to the S-CSCF.

In step s514, the S-CSCF sends the converted SIP report to the UE.

Step s515, the UE sends a success response to the S-CSCF.

Step s516, the successful response is forwarded to the interworking server by the S-CSCF.

The above steps s501 to s516 take the processing of the interworking server on the IMS network at the calling side as an example, the processing of the interworking server on the IMS network at the called side is similar, and will not be repeated here.

In the second embodiment of the present invention, taking the acquisition method as an example: the intercommunication server obtains the address of the short message service center from the received message based on the SIP protocol as an example, a method of routing a message based on the SIP protocol in a traditional network in the present invention is described. The specific implementation of the method.

In this embodiment, the UE carries the address of the short message service center in the message based on the SIP protocol sent by the UE, so that when the interworking server performs message processing, it adds the address of the short message service center obtained from the message based on the SIP protocol to the format-converted short message, so that the converted short message can be routed to the short message service center.

A specific scenario of the above process is shown in Figure 6, taking the processing of the IMS network on the calling side by the interworking server as an example, including the following steps:

Step s601, through the IMS registration process, the UE is registered with the S-CSCF.

In step s602, the UE sends a SIP message to the S-CSCF, and adds the address of the short message service center in the SIP message.

Specifically, the UE needs to add the address of the short message service center in the SIP message sent. Since the short message service center address will be solidified and stored in the UE's SIM card, when the calling UE sends a SIP message, it will carry the short message service center address obtained from the SIM card in the message header or message body of the SIP message parameter (the parameter may be a parameter of the existing SIP protocol, or a parameter of the extended SIP protocol), and send it through the IMS core network.

In step s603, the S-CSCF forwards the SIP message to the interworking server based on the iFC.

Step s604, the interworking server determines whether interworking at the service level is required by checking the SIP header, operator policy, or whether the SIP message can be routed by the called IMS, and if it decides to perform intercommunication at the service level, the interworking server authorizes the service . If the authorization fails, the interworking server returns a failure report to the UE. The failure is irrelevant to the embodiment of the present invention and will not be introduced here.

In steps s605-s606, after the authorization is successful, the interworking server returns a success response to the UE.

Step s607, the interworking server checks that the received SIP message is in a message format that does not encapsulate any SM message (such as SIMPLE IM/CPM message). Then the interworking server obtains the address of the short message service center from the SIP message.

Steps s608-s609, the interworking server converts the SIP message into a traditional short message, adds the short message service center address obtained in step s607 to the address information of the short message, and routes the short message to the traditional network routing entity SMS-IWMSC .

Steps s610 to s616 are the same as the above steps s510 to s516, and will not be described repeatedly here.

In Embodiment 3 of the present invention, taking the obtaining method as follows: the interworking server obtains the address of the short message service center from the third-party registration message received by the S-CSCF as an example, to illustrate a message based on the SIP protocol in the present invention in a traditional network The specific implementation of the routing method.

In this embodiment, in the third-party registration process, the application operator carries the short message service center address in the parameter (service info) of iFC, and carries the address information to the interworking server through the user's third-party registration, so that the interworking server can know the user The binding relationship between the information and the address of the short message service center, so that the format-converted short message can be routed to the short message service center in the subsequent routing of the interworking service.

A specific scenario of the third-party registration process is shown in Figure 7, including the following steps:

In step s701, the UE establishes an IP connection.

In step s702, the UE registers with the S-CSCF through the IMS registration process.

In this step, the iFC in the user subscription data downloaded by the S-CSCF from the HSS carries a parameter indicating the address of the short message service center.

Step s703, the S-CSCF checks the initial filtering rules obtained from the HSS during the IMS registration process.

In step s704, the S-CSCF initiates a third-party registration, and notifies the interworking server of the registration status of the user based on the initial filtering rule. The third party registration message carries the short message service center address acquired by the S-CSCF in step s702.

Step s705, the interworking server returns a success response to the S-CSCF.

In step s706, the interworking server acquires the address of the short message service center related to the registered user, and stores the association relationship between the address of the short message service center and the user information.

Step s707, the interworking server sends a registration request to the HSS.

Step s708 , the HSS stores the received information when needed, and uses it to inform the UE of becoming reachable in the IMS domain through an alarm message when the message waiting bit is set.

Step s709 , after the registration is successfully completed, the HSS checks whether the message waiting bit is not set, and whether an alarm procedure needs to be initiated.

After the third-party registration process in steps s701 to s709, the interworking server obtains the association relationship between the address of the short message service center and the registered user. In the subsequent IMS-MO process, when the interworking server receives the message based on the SIP protocol and successfully authorizes the interworking service, it can use the user information carried in the message based on the SIP protocol (generally, if the interworking server is in the The calling network just uses the information of the calling user, otherwise the information of the called user is used) to obtain the short message service center address corresponding to the user saved when the third party registers, and add the short message service center address in the format conversion in the subsequent short message so that the message can be routed to the short message service center. For this process, it is similar to the IMS-MO process in the prior art shown in Fig. 3, only the step of adding the short message service center address obtained by the interworking server to the short message after the format conversion is added, which is not done here Repeat description.

In Embodiment 4 of the present invention, taking the acquisition method as follows: the intercommunication server obtains the short message service center address according to the corresponding relationship between the locally configured user information and the corresponding short message service center address as an example, to illustrate a method based on the SIP protocol in the present invention. A specific implementation of the method for routing messages in traditional networks.

In this embodiment, the application operator directly configures the address information of the short message service center corresponding to the user number segment on the interworking server, so that the interworking server can find the corresponding short message according to the user information when performing the IMS-MO interworking service. The address of the service center, so that the format-converted short message can be routed to the short message service center. Specifically, this configuration can be a static configuration. The operator can configure the corresponding SMS center address according to the fixed number segment information. For example, users of 130/133 correspond to SMS center A, and users of 134/135 correspond to SMS Center B, etc.; in addition, the operator can also dynamically configure the address of the short message service center for the user according to the load balance of the network and the failure of the network, so that the network resources can be used more reasonably and the processing of the short message service can be optimized .

In this embodiment, after the step of directly configuring the corresponding relationship between user information and the address of the short message service center on the interworking server is added, the specific flow of IMS-MO is basically the same as that of the prior art. After successfully authorizing the interworking service, it can be found in the configuration list according to the user information carried in the instant message (if the interworking server is in the calling network, use the information of the calling user, otherwise use the information of the called user) The saved short message service center address corresponding to the user, when performing intercommunication business processing, carry the short message service center address in the short message after format conversion, so that the message can be routed to the short message service center. For this process , will not be repeated here.

In addition, the above-mentioned embodiments can also be applied to the situation of processing other messages based on the SIP protocol and interworking with traditional short messages. For example, for the CPM service: when the calling CPM user sends a message based on the SIP protocol to another CPM user, if the called user is unreachable on the called side network, then according to the operator's policy and user preference, the SIP The message is routed to the interworking server on the called side, and the call message is delivered through the traditional domain using the interworking service at the service level. In addition, when the calling CPM user sends a message based on the SIP protocol to another non-CPM user, but the user is an IMS subscriber, the SIP message is routed to the IMS core network on the called side, and through the subscription information of the called user, The IMS core network routes the SIP message to the interworking server on the called side, and uses the interworking service at the service level to deliver the message through the traditional domain. In both cases, the address of the short message service center can be obtained through the solutions provided by the above embodiments, so that the format-converted short message can be routed to the short message service center.

By using the methods provided in the above embodiments, the interworking server obtains the address of the short message service center and adds it to the short message obtained after the message conversion based on the SIP protocol, so that the format converted short message can be routed to the short message service center , realizing the routing of SIP-based messages in traditional networks after format conversion.
