Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a device, and an apparatus for interconnecting devices in different networks.
Background
IMS is an Internet Protocol (IP) Multimedia Subsystem, which is called IP Multimedia Subsystem, and is a main technology for implementing convergence and intercommunication among different offices of a heterogeneous Network or a homogeneous Network in a Next Generation Network (NGN), including convergence and intercommunication of networks such as 3G/4G Network for mobile communications, PSTN (Public Switched Telephone Network) and VoIP (Voice over Internet Protocol). The heterogeneous network may be a network formed by two or more networks using different access technologies. Different offices of a homogeneous network may be networks using the same access technology but belonging to different operators. Of course, different offices of the homogeneous network are not limited to the above definition, and may also be different networks obtained by dividing the networks using the same access technology based on a preset dividing means, such as gateway division, webmaster division, network layer division, or logic division.
In consideration of the device capability, the dialing habit of the user, the storage of the server, the routing, the authentication of the user, the load balancing and other reasons among different offices of the heterogeneous network or the homogeneous network, the user identifiers are not only different in format type, but also different in the same number expression form, Uniform Resource Identifier (URI) type and the like. Because the user identifiers used by different offices of the heterogeneous network or the homogeneous network are different, an important problem to be solved when the different offices of the heterogeneous network or the homogeneous network are fused and intercommunicated is how to mutually convert the user identifiers used by the different offices of the heterogeneous network or the homogeneous network.
The existing interconnection of devices between different offices of heterogeneous networks or homogeneous networks is implemented by gateways, such as: a Media Gateway Control Function (MGCF) Gateway and a Breakout Gateway Control Function (BGCF) Gateway, where IMS and Circuit Switched Domain (CSD) are interconnected; a Voice gateway used for intercommunication between a Voice over Internet Protocol (VoIP) network and an IMS; interworking between IMS networks is achieved by querying a CSCF (I-CSCF) gateway or other gateways, where CSCF is a Call Session Control Function and is referred to as Call Session Control Function.
In the prior art, network interconnection among different offices of a heterogeneous network or a homogeneous network is realized through a gateway, and under the major trend of IMS network convergence, the prior art has the following defects and shortcomings:
1. poor flexibility of gateway handling subscriber identity
The gateway processes the user identifier, which is commonly referred to as "prefix" processing, for example, adding a prefix to a number to enable a network that recognizes the prefix to recognize the number; the number complementing processing or the number removing processing, etc., but the format type of the user identification is diversified, and the processing of the format type of the user identification by the gateway involves less.
2. Gateway management boundary limitation
The gateway is limited to managing the current inter-office or inter-network interworking.
3. The user identification processing strategies of different types of gateways are different, the newly added gateway needs to be reconfigured with the user identification processing strategy, and under the large trend of IMS network convergence, the prior art has low convergence efficiency
The user identification processing strategies of different types of gateways are different, for example, the gateway for realizing the intercommunication between the network A and the network B adopts the user identification processing strategy 1, the gateway for realizing the intercommunication between the network B and the network C adopts the user identification processing strategy 2, and if a new gateway needs to be added to realize the intercommunication between the network A and the network C, the new gateway needs to be configured with a new user identification processing strategy.
4. The gateways are of various types and are not convenient for unified management
Because the user identification processing strategies of different types of gateways are different, when the number of points of intercommunication between networks is more, the types of the related gateways are more, the number of management points of the user identification processing strategies is more, and unified management is inconvenient.

The process of interaction between the device and the apparatus initiating the interconnection is detailed below.
The preset user identifier analysis rule in the device can describe the user identifier format in a form of a table, is a structural description of the user identifier format and is used for analyzing the user identifier.
Taking a user identifier in Sip (Session Initiation Protocol) format and a user identifier in Tel format as examples, the user identifier of the device initiating interconnection is in Tel format, for example, Tel: +8613912345678. The user format of the devices waiting for interconnection is Sip format.
The preset user identification analysis rule in the device is shown in a table I.
Table-user identification parsing rule
The entries in the first table may be set based on Uri's specification of a Uniform Resource Identifier (Uniform Resource Identifier), for example, including Uri category, user name, Domain, Phone-context waiting for mobile Phone number content. No indicates the absence of this term. The record ID indicates the ID of the user identification resolution rule.

By way of example only, those skilled in the art may determine the user id parsing rule according to actual situations.
The device analyzes the rule based on the user identification shown in the table one, and the user identification Tel of the device initiating interconnection is: +8613912345678 resolution may result in user identification resolution information for the device initiating the interconnection as shown in table two.
User identification resolution information of table two-initiated interconnected devices
The device analyzes the user identifier of the equipment to be interconnected based on the user identifier analysis rule shown in the table I to obtain the user identifier analysis information of the equipment to be interconnected shown in the table III.
User identification resolution information of devices waiting for interconnection
The device sends an interconnection feedback message carrying the user identification analysis information of the interconnection initiating device and the user identification analysis information of the interconnection waiting device to the interconnection initiating device, so that the interconnection initiating device is interconnected with the interconnection waiting network based on the user identification analysis information of the interconnection initiating device and the user identification analysis information of the interconnection waiting device.
Of course, the apparatus may convert the user identifier of the device initiating interconnection into the target user identifier matching the user identifier resolution information of the device waiting for interconnection based on the user identifier resolution information of the device initiating interconnection and the user identifier resolution information of the device waiting for interconnection. Specifically, the user identification Tel of the device that will initiate the interconnection: +8613912345678 to Sip format for the user identification of the device waiting for interconnection:
Sip:008613912345678@dtmobile.cn；user＝phone
where "@ dtmobile. cn" may be derived from a domain name in the configuration information of the device initiating the interconnection.

After receiving the interconnection request message, the device analyzes the user identifier of the interconnection initiating equipment and the user identifier of the interconnection waiting equipment based on a preset user identifier analysis rule to obtain user identifier analysis information of the interconnection initiating equipment and user identifier analysis information of the interconnection waiting equipment, and sends the user identifier analysis information to the interconnection initiating equipment through an interconnection feedback message.
After receiving the interconnection feedback message, the interconnection initiating device stores the user identification analysis information of the interconnection initiating device and the user identification analysis information of the interconnection waiting device in a local database for subsequent use, and when the user identification analysis information is effective (the recorded TTS does not exceed the limit), the interconnection request message does not need to be sent to the device. When the subscriber identity resolution information is invalid, an interconnection request message needs to be sent to the device.
When the device initiating interconnection queries the local database, and the user identifier analysis information of the device initiating interconnection and the user identifier analysis information of the device waiting for interconnection can be obtained and are both valid, the user identifier analysis information can be directly used to convert the user identifier of the device initiating interconnection into the target user identifier matched with the user identifier analysis information of the device waiting for interconnection. And then, modifying the signaling by using the target user identification, and sending the signaling to the equipment waiting for interconnection to realize interconnection.
Fig. 11 is a second schematic diagram of signaling interaction between a device initiating interconnection and a device, and an application scenario of fig. 11 updates user identifier resolution information for the device.
After the user identification analysis rule shown in the table I is updated, the device can obtain the user identification analysis information of the equipment corresponding to the equipment ID recorded in the updated table I.
And the device sends an update message to the equipment corresponding to the equipment ID recorded in the table I, wherein the update message carries the correspondingly updated user identification analysis information.
And after receiving the updating message, the equipment stores the updated user identifier analysis information, resets TTS (time to live) of the user identifier analysis information as an initial value, and sends an updating feedback message to the device so as to ensure that the device determines that the equipment updates the user identifier analysis information.
Fig. 12 is a third schematic view of signaling interaction between a device initiating interconnection and a device, where an application scenario of fig. 12 is a failure of the device to acquire user identifier resolution information.
The device initiating interconnection sends an interconnection request message to the device;
if the device fails to acquire the user identifier analysis information, sending an interconnection feedback message carrying indication information of the failure of acquiring the user identifier analysis information to the interconnection initiating equipment;
after receiving an interconnection feedback message carrying indication information of failure in obtaining the user identification analysis information, the interconnection initiating equipment sends an interconnection request message to the device again at intervals of preset duration until obtaining the user identification analysis information of the interconnection initiating equipment and the user identification analysis information of the interconnection waiting equipment.
