Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Fig. 1 is a schematic diagram of some embodiments of a communication system for implementing an IMS service according to the present disclosure.
As shown in fig. 1, the system of this embodiment includes:
an IMS service platform 11 (which may be referred to as a "service platform" for short),
the interworking network device 12 is a device that is,
the IMS domain 13 is a domain in which the IMS,
the IMS service platform 11 and the IMS domain 13 are in communication connection with the interworking network device 12. The IMS service platform 11 and the IMS domain 13 may use a standard SIP protocol to perform interworking with the newly-built interworking network device 12. There are typically multiple IMS domains 13, which may be deployed in different geographical locations, e.g. one IMS domain for each province.
Therefore, each IMS domain can share the IMS service platform and various innovative IMS voice services provided by the IMS service platform through the intercommunication network equipment, each IMS domain only needs to be connected with one network element (namely intercommunication network equipment) in a butt joint mode, and does not need to be connected with each IMS service platform in a butt joint mode, and related voice innovation service platforms are high in expansibility and rapid in deployment.
The network networking structure of the present disclosure is clear, and the function division of each network element is clear. And realizing the overall coordination scheduling of the intensive networking through the intercommunication network equipment. The interworking network device mainly implements functions such as routing, signaling processing, number normalization, etc. in the aspect of network networking. The IMS service platform focuses on implementing the relevant functions in the innovative voice service aspect. The IMS domain routes the call to the interworking network device using triggering methods such as an IFC (Initial Filter criterion), a PSI (public service identity), and a fixed access code according to different service characteristics.
In some embodiments, interworking network device 12 includes interworking gateway device 121 and number translation device 122. The IMS service platform 11 and the IMS domain 13 are communicatively connected to the interworking gateway device 121, and the interworking gateway device 121 is communicatively connected to the number translation device 122. The overall coordination scheduling of the intensive networking is realized through the cooperation of the interworking gateway equipment and the number translation equipment.
The interworking gateway device 121 is respectively connected to the IMS domain of each province and various IMS service platforms by using a standard SIP (Session Initiation Protocol), so that a function of overall scheduling of cross-domain IMS services can be realized.
The realized functions comprise ① signaling TLS encryption, ② interaction with number translation equipment, user attribution domain query and cell phone H code query translation, functions of adding 0 to a called cell phone number when a calling number and a called number do not belong to the same area code, ③ routing analysis function, ④ anti-theft function, such as IP dialing restriction and international long distance dialing restriction, ⑤ number regulation function, ⑥ voice coding and decoding conversion, ⑦ interaction with number translation equipment, such as domain name conversion to IP address, and the like.
The functions implemented by the number translation device 122 include, for example, ① performing domain name and IP address conversion functions, ② performing mobile phone H-code translation into area code plus mobile phone number format functions, and so on.

The intercommunication gateway device adopts a standard ISC interface to intercommunicate with an ICSCF network element or an SCSCF network element of each IMS domain. For IMS fixed telephone users, the SBC, PCSCF and SCSCF cooperate with the intercommunication gateway equipment to provide services for the users. For non-IMS fixed telephone users, the soft switch device, MGCF, ICSCF cooperate with the intercommunication gateway device to provide services for the users. For mobile phone users, the MGCF and the ICSCF cooperate with the intercommunication gateway device to provide services for the users.
Fig. 2 is a schematic diagram of some embodiments of the communication system implementing the IMS service and the interworking network device therein according to the present disclosure.
As shown in fig. 2, the interworking gateway device 121 includes, for example: a call routing unit 121a, a number normalization unit 121b, a signaling header normalization unit 121c, a call stealing prevention processing unit 121d, an encryption unit 121e, a coding/decoding conversion unit 121f, an SIP protocol unit 121g, a Diameter protocol unit 121h, and the like. The number translation apparatus 122 includes, for example: a mobile phone number translation unit 122a, a number routing and addressing translation unit 122b, a Diameter protocol unit 122c, etc.
The call routing unit 121a is configured to select a corresponding IMS service platform or IMS domain for call connection according to the call routing reference information. For example, call routing is performed according to a calling number or a called number or a service type or a routing access code in a call signaling flow. The call routing includes two aspects, namely, selecting a corresponding service platform on one hand, and selecting different IMS domains on the other hand, thereby realizing call connection.
The number normalization unit 121b is configured to perform number normalization processing on the related numbers. For example, a calling number or a called number or a service trigger number in a call signaling flow is structured, where the structured processing includes converting number formats, structured according to a specified number type, deleting number prefixes or adding number prefixes, and the like. For example, the called number normalization is an example in which a calling subscriber dials only a called number without adding a country code or a region code prefix, and a global number is obtained by complementing the country code or the region code prefix on the basis of the called number through the called number normalization.
And a signaling header field regulating unit 121c, configured to regulate the relevant signaling header fields according to different service requirements. For example, after the number of call forwarding times in the History-info header field of the Invite message is reduced by 1, a new Invite message is initiated, so as to avoid processing such as abnormal call occurrence caused by the number of call forwarding times exceeding a threshold set by a relevant network element.
And the anti-pirate processing unit 121d is used for performing connection or disconnection processing on the call of the specified prefix or number. For example, a blacklist or a white list or a function of preventing fraudulent calling is set based on the number, the area code, the international code, etc., when the blacklist is satisfied, the call of the appointed prefix or number is connected, and when the blacklist is satisfied, the call of the appointed prefix or number is not connected, etc., so that the security is increased.
An encrypting unit 121e, configured to encrypt the signaling. For example, the signaling is encrypted in an encryption manner such as TLS (Transport layer encryption), thereby enhancing security.
A codec converting unit 121f, configured to convert the codec. For example, voice codecs in the call signaling flow are converted according to the service requirements.
And the SIP protocol unit 121g is configured to run an SIP protocol, and implement communication connection with the SIP service platform and the IMS domain.
And the Diameter protocol units 121h and 122c are configured to run a Diameter (Diameter, authentication, authorization, accounting, AAA, protocol standard) protocol to implement a communication connection between the interworking gateway device and the number translation device.
The mobile phone number translation unit 122a is configured to perform H-code translation on the called mobile phone number. The H code translation means that 11-bit mobile phone numbers are translated into + 11-bit mobile phone numbers so as to perform call routing according to the translated area codes. For the condition that a calling party dials a called mobile phone number with a non-identical area code, 0 is added in front of the called mobile phone number through H code translation, so that the problem that an IMS system at the called side cannot perform subsequent number analysis is solved.
A number routing and addressing translation unit 122b, configured to complete conversion between the domain name and the IP address, and convert the TEL format of the number into the SIP format, for example, convert a TEL (telephone) URI (Uniform Resource Identifier) into a SIP (Session Initiation Protocol) URI. The PSI may for example be in sip URI format or Tel URI format.
IMS service triggers can be divided into two categories. One is control trigger service, and the service initiation point is an IMS service platform, such as multi-party call, voice notification and other services. The other type is a call triggering type service, the service starting point is a mobile phone or a fixed telephone terminal, and the IMS service platform passively receives the call and realizes a voice innovation service, such as a number conversion type service.
Fig. 3 is a schematic flow chart of an IMS service platform actively initiating a voice service according to some embodiments of the present disclosure.
As shown in fig. 3, this embodiment includes:
step 31: the user initiates a voice call through a WEB page or a mobile phone APP, and submits a call request to a voice service platform (i.e. an IMS service platform for a certain service).
Step 32: after the call request is submitted to the voice service platform, the voice service platform completes the relevant service processing in combination with the voice service logic corresponding to the call request, and then routes the call request to the intercommunication gateway device.
The call sent by the voice service platform to the interworking gateway device is set as a first call, the first call is used for a calling party (the number of the calling party is a calling number a) to call a called party (the number of the called party is a called number b), and the first call comprises the calling number a and the called number b.
Step 33: the interworking gateway device responds to the first call, and processes the related number information and signaling header field information, for example, adding access code information, number conversion, conversion processing of a certain signaling header field, H-code translation of the calling/called mobile phone number to determine the attributive IMS field, and the like. After the relevant signaling and number processing, the interworking gateway device performs steps 34a and 34b, respectively, in conjunction with the service processing requirements.
It should be noted that the associated signaling and number processing to be done by different traffic logics may be different. For example, some service logics need to add an access code (e.g. 117) to the called number, and the interworking gateway device routes the 117 to the designated IMS domain, and then the IMS domain completes the subsequent call routing. The number conversion means that a calling number or a called number in a calling process is modified into another number according to a preset service logic rule. The processing of the signaling header field refers to initiating a new Invite message after subtracting 1 from the number of call forwarding times in the History-info header field of the Invite message, so as to avoid processing such as abnormal call occurrence caused by the number of call forwarding times exceeding a threshold set by a relevant network element.
Step 34a, the interworking network device initiates a second call to the IMS domain corresponding to the calling number.
The interworking network equipment initiates a second call to the calling number by using the calling display number, and selects the IMS domain to which the calling number belongs or the IMS domain to which the calling display number belongs to route the second call. Fig. 3 shows the case where the IMS domain to which the calling number belongs routes the second call.
The calling display number may be a third number different from the calling number and the called number, or may be the calling number.
And the ICSCF network element in the IMS domain through which the second call passes selects a corresponding network element according to the type of the calling number to complete call connection.
For example, the interworking network device sends the second call to an ICSCF network element in an IMS domain to which the calling number belongs, and if the calling number is a fixed-line subscriber in the IMS domain, completes subsequent call connection through the SCSCF network element, and connects to the calling subscriber corresponding to the calling number. If the calling number is the non-fixed telephone user of the IMS domain, the subsequent call connection is completed through the MGCF network element, and the call connection is continued to the calling user corresponding to the calling number.
For example, the interworking network device sends the second call to the ICSCF network element in the IMS domain to which the calling display number belongs, if the calling number and the calling display number are in the same IMS domain, the subsequent connection process is consistent with the previous content, and if the calling number and the IMS domain of the calling display number are different, the ICSCF network element in the IMS domain to which the calling display number belongs connects the call to the IMS domain to which the calling number belongs via the MGCF network element, and further connects to the calling subscriber corresponding to the calling number.
Step 34 b: and the interworking network equipment initiates a third call to the IMS domain corresponding to the called number. Thus, call signaling between the calling subscriber and the called subscriber is established through the second call and the third call.
The interworking network equipment initiates a third call to the called number by using the calling display number, and selects the IMS domain to which the called number belongs or the IMS domain to which the calling display number belongs to route the third call.
And the ICSCF network element in the IMS domain through which the third call passes selects a corresponding network element according to the type of the called number to complete call connection.
For example, the interworking network device sends the third call to an ICSCF network element in an IMS domain to which the called number belongs, and if the called number is a fixed-line subscriber in the IMS domain, completes subsequent call connection through the SCSCF network element and connects to a called subscriber corresponding to the called number, and if the called number is a non-fixed-line subscriber in the IMS domain, completes subsequent call connection through the MGCF network element and connects to a called subscriber corresponding to the called number.
For example, the interworking network device sends the third call to the ICSCF network element in the IMS domain to which the calling display number belongs, if the called number and the calling display number are in the same IMS domain, the subsequent connection process is consistent with the previous content, and if the called number and the IMS domain of the calling display number are different, the ICSCF network element in the IMS domain to which the calling display number belongs connects the call to the IMS domain to which the called number belongs via the MGCF network element, and further connects to the called user corresponding to the called number.
Therefore, the IMS service platform can actively initiate voice service.
Fig. 4 is a schematic flow chart of an IMS service platform passive triggering service according to some embodiments of the present disclosure.
For the scenario that the service needs to be routed to the service platform to trigger the service, the IMS domain of each province can use the triggering modes such as IFC, PSI, or fixed access code according to different service characteristics, and first route the call to the interworking gateway device, and then route the call to the interworking gateway device according to the judgment conditions such as the prefix of the relevant service by combining with different service characteristics, and route the call to different service platforms to complete the subsequent service processing.
In this embodiment, a number translation service of a called number is taken as an example to describe a flow of a passive service triggering by an IMS service platform.
The service mobile phone number which needs to realize number conversion is transferred to the designated number by registering unconditional calling, and the related network element routes the designated number calling to the IMS domain of the attribution province by data configuration. The IMS of the province of affiliation routes the call to the newly-built interworking gateway equipment according to the triggering modes of IFC, PSI or fixed access code, etc., for example, the appointed number is used as a fixed access code, the account is opened according to the PSI identity, and the method is set as a PSI triggering mode, the call is triggered to the service platform through the interworking gateway equipment, and the service platform completes the triggering of the relevant service logic of number conversion. And after the service triggering is finished, the service platform completes the subsequent call continuing processing through the IMS domain of the service triggering number attribution province by the intercommunication gateway equipment. All province users under the same operator can sign number conversion services provided by the same service platform based on the networking architecture, and the IMS cross-domain sharing service triggering is realized.
As shown in fig. 4, taking the number translation class service of the called number as an example for explanation, the flow of the service platform passively triggering the service includes:
step 41: the calling user dials the mobile phone service number signed with the number conversion service, and the call is sent to the mobile phone network of the place where the called mobile phone service number belongs to by the calling user side through the related network element.
Step 42: the mobile phone network of the location where the mobile phone service number belongs judges that the user signs a service with number conversion class, carries out the call forwarding process triggered by the service, forwards the service to a specific access code, and then configures the call to pass through the IMS domain of the province where the mobile phone service number belongs according to the data of the access code.
Step 43: and the IMS of the mobile phone service number attribution province triggers the call to the interworking gateway equipment according to the access code.
Step 44: the intercommunication gateway device selects the call route to the appointed service platform according to the access code and the calling and called number information, simultaneously deletes the corresponding access code information, and normalizes the number into the appointed format of the service platform.
Step 45: the service platform processes the service logic after receiving the call, converts the called service number into a corresponding connection number according to the service logic, and transfers the new call to the intercommunication gateway equipment.
Step 46: after receiving the call, the intercommunication gateway device processes the related signaling header field, number normalization, etc. in the call in combination with the related number information, CALLID (cell identification), etc., and at the same time, interacts with the number translation device to determine the area number of the province to which the new called number (i.e. the continuing number) belongs, and then the intercommunication gateway device routes the call to the corresponding home IMS domain according to the area number to perform the subsequent call continuing process.
Step 47: finally, the network element to which the continuing number belongs initiates a call to the user after receiving the call, and the calling party and the called party can communicate after the user is off-hook and connected.
The innovative voice service platform and each IMS domain adopt a standard SIP protocol to communicate with the newly-built intercommunication gateway equipment. For the service platform to passively trigger the service, the IMS system of the called service number attribution province routes the call to the newly-built intercommunication gateway equipment according to the triggering modes of IFC, PSI or fixed access code, and the intercommunication gateway equipment cooperates with the newly-built number translation equipment and the service platform to interactively complete the subsequent service and call processing.
Based on the disclosure, all fixed phone users and mobile phone users can flexibly share voice innovation services (such as services in the aspects of number conversion and the like) provided by the service platform, and can route calls to an IMS (IP multimedia subsystem) domain of a number attribution province for connection according to different numbers in a call flow. Meanwhile, the user can also utilize WEB webpage, APP and other modes to provide related voice innovation functions by means of the voice service platform; using fixed phone or mobile phone number as calling display number to initiate different forms of voice call (such as multi-party call, voice notification, etc.); the call can be routed to the home IMS domain of the calling display number for routing connection; and telephone traffic is shunted nearby according to the IMS domain of the province to which the calling number or the called number belongs, so that the cross-province telephone traffic detour and inter-province settlement are reduced, and the national voice innovation service can be developed quickly and massively.
