Description

Cross-service area message interaction method and device based on information catalogue, electronic equipment and storage medium

Technical Field

The disclosure relates to the technical field of communication, in particular to a cross-service area message interaction method based on an information directory.

Background

Under the scene that the security requirement is higher, the different service areas are communicated through the inter-area channels, and the inter-area gateway only opens a very limited number of ports to the outside, so that the communication flow between the different service areas can be conveniently checked, and effective long links cannot be established between the different areas under the condition. And for outdoor maneuvers a limited number of motorized vehicles make up a service area that is connected to a fixed service center (also a service area) through a wireless network, while jitter, delay, etc. of the wireless network are intolerable and manageable for the business service.

At present, the conventional service message clusters on the Internet basically do not exist in the cross-service area condition, and one set of message clusters is often only used in a certain service scene; and the conventional service on the internet basically has no condition that long links can not be established between gateways. Therefore, in the case that the requirements on the security of information transfer between the cross-service areas are high, and the network between the cross-service areas cannot establish an effective long link, especially in the case that the outdoor mobile operation network is poor, it is not practical to directly access other regional message service clusters through the message client in the region to obtain the required message (the message client directly accesses the message clusters generally needs to maintain the long link). Therefore, how to improve the efficiency of message interaction across service areas under the above conditions is a current urgent problem to be solved.

FIG. 1 illustrates a schematic diagram of an exemplary operating environment in which embodiments of the present disclosure can be implemented, as shown in FIG. 1, in which operating environment 100 may include subscription service areas and publication service areas, which may include business services, message servers, message trans-regional services, information directories, trans-regional gateways, and the like.

As one example, a business service subscribing to a business region may conduct a cross-regional message subscription to a business service publishing the business region through a message cross-regional service subscribing to the business region.

Specifically, the business service subscribing to the business region may send a first cross-region message subscription request to a message cross-region service subscribing to the business region.

The message cross-regional service of the subscription service region adds a subscription record in a subscription list of an information catalog of the subscription service region according to the first cross-regional message subscription request, and sends a second cross-regional message subscription request to the message cross-regional service of the release service region, namely sends the second cross-regional message subscription request to the message cross-regional service of the release service region through the subscription service region and a cross-regional gateway of the release service region.

And the message cross-regional service of the release service region adds a release record in a release list of the information catalogue of the release service region according to the second cross-regional message subscription request, and sends a third cross-regional message subscription request to the message server of the release service region.

The business services of the publishing business region can perform cross-region message publishing to the business services of the subscribing business region through the message cross-region services of the publishing business region.

Specifically, the service of the publishing service area may send a message to a message server of the publishing service area;

and the message service end of the release service area sends the message to the message cross-region service of the release service area.

The message cross-regional service of the publishing service region inquires a publishing list of the publishing service region, and sends a message to the message cross-regional service of the subscribing service region according to the domain name of the subscribing service region in the publishing record obtained by inquiry, namely sends the message to the message cross-regional service of the subscribing service region through the cross-regional gateways of the publishing service region and the subscribing service region.

The method for cross-service area message interaction based on the information directory according to the embodiment of the present disclosure will be described in detail, wherein the method for message interaction may be applied to the operating environment 100 shown in fig. 1.

Fig. 2 shows a flowchart of a cross-service area message interaction method based on an information directory according to an embodiment of the disclosure, and as shown in fig. 2, the message interaction method 200 may include the following steps:

s210, subscribing the business services of the business region to perform cross-region message subscription to the business services of the publishing business region through the message cross-region services of the subscribing business region.

Specifically, the service subscribing to the service area sends a first cross-area message subscription request to a message cross-area service subscribing to the service area, where the first cross-area message subscription request may include: message subject name, post service area domain name, business service client number.

In some embodiments, the service subscribing to the service area may send a message subscription request including a message header name and a service client number to a message service end subscribing to the service area through an embedded message client, and record a subscription list of the message service end, where the message client may determine according to a form of the message header name, and if the message subscription request is in a form of domainname, topicName, i.e. a service area domain name+a message header name, the message subscription request is determined to be a request subscribing to other areas, and the message header name is changed to a form of TopicName, and then a first cross-area message subscription request is sent to a message cross-area service subscribing to the service area, where the message header name in the first cross-area message subscription request is the changed message header name, the service area name is a service area domain name in the original message header name, and the service client number is used to identify the service initiating the message subscription.

The message cross-regional service of the subscription service region receives a first cross-regional message subscription request, adds a subscription record in a subscription list of an information catalog of the subscription service region according to the first cross-regional message subscription request, and sends a second cross-regional message subscription request to the message cross-regional service of the release service region.

The subscription record may include a message header name, a domain name of the publishing service area, a domain name of the original publishing service area, and a number of a service client, where the content of the domain name of the original publishing service area is NULL, that is, a NULL value. For example: the subscription record may be in the form of [ TopicName, publishDomain, outdatedPublishDomain, clientID ], where TopicName represents the message header name, publishDomain represents the post service area domain name, outdedPublishDomain represents the original post service area domain name, and ClientID represents the business service client number. The second cross-zone message subscription request may include: message subject name, subscription service area domain name.

In some embodiments, if the message cross-regional service in the subscription service region queries the subscription record in which the message subject name, the domain name of the publishing service region is consistent with the message subject name and the publishing service region name in the newly added subscription record in the subscription list in the subscription service region, the operation can be stopped, and the cross-regional message subscription can be completed quickly.

If the message cross-regional service of the subscription service region does not inquire the subscription record of which the message subject name and the domain name of the publishing service region are consistent with the message subject name and the publishing service region name in the newly added subscription record in the subscription list of the subscription service region, the message cross-regional service of the subscription service region can send a second cross-regional message subscription request to the message cross-regional service of the publishing service region.

For example: the message cross-regional service of the subscription service region inquires whether a subscription list of the region has a message subject name, a publishing service region domain name and a newly added subscription record with the same message subject name and publishing service region name, and if so, a value of 2 is returned; otherwise, inquiring whether the other area information cross-regional service address list in the information catalog of the area has the information cross-regional service address corresponding to the domain name of the release service area, if not, returning a value of 0 and the whole area information catalog address in the information catalog of the area, otherwise, returning a value of 1 and the information cross-regional service address corresponding to the domain name of the release service area. The method comprises the steps that a whole-area information directory is deployed by means of a certain service area, an operator establishes an external mapping address of an intra-area message cross-area service on each inter-area gateway of the service areas, registers the address to the whole-area information directory, establishes an external mapping address of the whole-area information directory on the inter-area gateway where the whole-area information directory is located, and establishes mapping from an internal address of the inter-area gateway to the external mapping address of the whole-area information directory on each inter-area gateway; and registering the mapping addresses inside the regional cross-regional gateways in the information catalogues of the regions, wherein the information catalogue addresses of the regions where the whole region information catalogues are located are registered with the internal addresses of the regions where the whole region information catalogues are located.

If the message cross-regional service subscribed to the service region receives the return value of 2, the fact that other service services in the region have subscribed to the same publishing service region and the same message subject name is indicated, and the next operation is not performed.

If the message cross-regional service of the subscription service region receives the message cross-regional service address with the return value of 1 and corresponding to the domain name of the release service region, the message cross-regional service address list of other region messages of the region stores the message cross-regional service address of the release service region, but the region does not have the same subscription record, and a second cross-regional message subscription request is sent to the message cross-regional service of the release service region according to the message cross-regional service address of the release service region.

If the message cross-regional service of the subscribed service region receives the return value of 0 and the whole-region information directory address, the message cross-regional service of the subscribed service region indicates that the region does not initiate any access request to the published service region, so that the message cross-regional service address of the published service region is not stored, the message cross-regional service of the region splices the Domain name of the published service region (Domain 2 is set as the region name of the published service region) and the message cross-regional service name of the Msg as the published service region (Domain 2. Msg), then the message cross-regional service of the region initiates access to the whole-region information directory with the message cross-regional service name of the published service region, and further after the message cross-regional service of the published region is acquired from the whole-region information directory and the message cross-regional service of the published region is mapped to the address IP1, namely the message cross-regional service address of the published service region outside the cross-regional gateway, an address mapping channel establishment request for the regional trans-regional gateway is initiated, mapping from the inter-regional gateway internal address IP2 of the subscription service region to the trans-regional service address IP1 of the message of the release service region is established, an address record is newly added in the trans-regional service address list of other regions of the region, wherein the ServiceName writing Domain2.Msg, innerAddress is IP2, the OuterAddress is IP1, as known, the ServiceName represents a service name, innerAdddress represents the inter-regional gateway internal address of the region, namely the inter-regional gateway of the region is mapped to the internal address of a certain service, and OuterAddress represents the external address of other regional trans-regional gateways, namely the external address of the regional trans-regional gateway of the region. And further, a second cross-regional message subscription request can be sent to the message cross-regional service of the release service region according to the message cross-regional service address of the release service region.

The message cross-regional service of the release service region receives a second cross-regional message subscription request, adds a release record in a release list of an information catalog of the release service region according to the second cross-regional message subscription request, and sends a third cross-regional message subscription request to a message service terminal of the release service region.

Wherein the publishing record includes a message subject name and a subscription service area domain name. For example: the publication record may be in the form of [ TopicName, subscribeDomain ], where TopicName represents the message subject name and subsribedomain represents the subscription service area domain name. The third cross-zone message subscription request may include: message subject name.

In some embodiments, if the message cross-regional service in the release service region queries a release record with a message subject name consistent with the message subject name in the newly added release record in the release list in the release service region, the operation can be stopped, and the cross-regional message subscription can be completed quickly.

If the message cross-regional service of the release service region does not query a release record with the message subject name consistent with the message subject name in the newly added release record in the release list of the release service region, a third cross-regional message subscription request can be sent to the message service terminal of the release service region.

For example: the message cross-regional service of the release service region inquires whether a release record with the message subject name consistent with the message subject name in the newly added release record exists in the release list of the region, if so, the value of 1 is returned, and if not, the value of 0 is returned.

If the message cross-regional service of the publishing service region receives a return value of 1, the message cross-regional service of the region can not perform the next operation if the message cross-regional service of the region has received subscription requests of other service regions to the same message subject.

If the message cross-regional service of the publishing service region receives a return value of 0, the message cross-regional service of the region does not receive subscription requests of other service regions for the same message theme before the message cross-regional service of the region, and a third cross-regional message subscription request is sent to a message service end of the region to subscribe the message corresponding to the message theme.

S220, the business service of the release business region performs cross-region message release to the business service of the subscription business region through the message cross-region service of the release business region.

Specifically, the service of the release service area sends a message to the message cross-area service of the release service area through the message service end of the release service area.

The message cross-regional service of the release service region receives the message, queries the release list of the release service region, and sends the message to the message cross-regional service of the subscription service region according to the domain name of the subscription service region in the release record obtained by query.

In some embodiments, if the message cross-regional service address corresponding to the subscription service area name is queried in the message cross-regional service address list of other areas in the information directory of the publishing service area, the message cross-regional service of the publishing service area is quickly sent to the message cross-regional service of the subscription service area according to the queried message cross-regional service address.

And if the message cross-regional service address corresponding to the domain name of the subscription service area is not queried in the message cross-regional service address list of other areas in the information catalogue of the release service area, acquiring the message cross-regional service address of the subscription service area from the whole-area information catalogue according to the domain name of the subscription service area, and rapidly sending the message to the message cross-regional service of the subscription service area according to the acquired message cross-regional service address.

For example: the message cross-regional service of the publishing service region carries a message subject name to inquire a publishing list of the region, acquire a subscription service region domain name, inquire whether a message cross-regional service address corresponding to the subscription service region domain name exists in a message cross-regional service address list of other regions of the region, and if so, return [ "subscription service region domain name", "1", message cross-regional service address of the subscription service region ]; otherwise, return [ "subscribe to service area domain name", "0", full area information directory address ].

If the return value received by the message cross-regional service of the publishing service region is [ "subscribed service region domain name", "0", and the whole-region information directory address ], the message cross-regional service address of the subscribed service region is obtained from the whole-region information directory according to the subscribed service region domain name, and the specific steps are similar to those of the example in S210, and are not repeated here.

The message cross-regional service of the subscription service region inquires a subscription list of an information catalog of the subscription service region, adjusts the message subject name of the message according to the subscription record obtained by inquiry, and sends the message to a message server of the subscription service region.

The message service end subscribed to the service area sends a message to the corresponding service, for example, pushes a message to the client of the corresponding service according to the subscription list of the message service end.

In some embodiments, if the original publishing service area name in the obtained subscription record is a null value, the message cross-regional service of the subscription service area splices the domain name of the publishing service area with the message subject name of the message, takes the spliced subject name as the message subject name of the message, and sends the message to the message service end of the subscription service area;

For example, subscribing to business service 1 in business region Domain2 subscribes to message Domain2.TopicName, business service 2 subscribes to message Domain3.TopicName in business region Domain3, and subsequent business service 2 changes the release business region of TopicName to Domain2, so that message TopicName returned by Domain2 needs to be given to business service 1 as well as business service 2; because the theme name can not be changed in the program running process, the message TopicName returned by Domain2 needs to be issued to the message service end by taking the theme names of Domain2.TopicName and Domain3.TopicName at the same time, so that the service 1 and the service 2 can be conveniently received at the same time, and the flexibility of message subscription under the cross-regional environment is improved.

According to the embodiment of the disclosure, under the cross-service area environment, the information between different areas can be published and subscribed as required based on the information cross-area service in each area, so that the information interaction efficiency and the safety of the cross-service area are improved. Meanwhile, if a plurality of business services in a certain area need the same information of other areas, the other areas only need to transmit the information once to the area, and the plurality of identical information are not required to be transmitted, so that the bandwidth under the condition of outdoor maneuvering operation can be effectively saved.

In some embodiments, the business services subscribed to the business region may cross-region message unsubscribe from the business services publishing the business region through the message cross-region services subscribed to the business region.

Specifically, the service subscribing to the service region may send a first cross-region message unsubscribe request to the message cross-region service subscribing to the service region. Wherein the first cross-domain message unsubscribe request includes: message subject name, post service area domain name, business service client number.

The message cross-regional service of the subscription service region receives a first cross-regional message unsubscribe request, and if a subscription record of which the service client number, the message subject name, the domain name of the release service region are consistent with the service client number, the message subject name and the release service region name in the first cross-regional message unsubscribe request is queried in a subscription list of the subscription service region, the queried subscription record is deleted. If the subscription records, of which the message subject names and the domain names of the publishing service areas are consistent with the message subject names and the publishing service area names in the first cross-area message unsubscribing request, are found in the subscription list after the queried subscription records are deleted, cross-area message unsubscribing is completed. If the subscription list after deleting the queried subscription records does not query the subscription records of which the message subject names and the domain names of the publishing service areas are consistent with the message subject names and the publishing service area names in the first cross-area message subscription cancellation request, sending a second cross-area message subscription cancellation request to the message cross-area service of the publishing service area. Wherein the second cross-zone message unsubscribe request includes: message subject name, subscription service area domain name.

The message cross-regional service of the publishing service region receives a second cross-regional message unsubscribe request, and deletes the publishing records of which the message subject names and the subscription service region domain names are consistent with the message subject names and the subscription service region names in the second cross-regional message unsubscribe request in the publishing list of the publishing service region. And if the queried published records with the message subject names consistent with the message subject names in the second cross-regional message unsubscribe request are queried in the published list after deleting the queried published records, finishing cross-regional message unsubscribe. If the publishing record with the same message subject name as the message subject name in the second cross-regional message unsubscribe request is not queried in the publishing list after deleting the queried publishing record, a third cross-regional message unsubscribe request is sent to the message server side of the publishing service area. Wherein the third cross-zone message unsubscribe request includes: message subject name.

The message cross-regional service of the subscription service region receives a third cross-regional message unsubscribe request, if a subscription record that the service client number, the message subject name, the original publishing service region domain name are consistent with the service client number, the message subject name and the publishing service region name in the first cross-regional message unsubscribe request is queried in a subscription list of the subscription service region, the queried subscription record is deleted, a message unsubscribe flow corresponding to the queried subscription record is executed, and specific steps are similar to the message unsubscribe steps and are not repeated herein.

Therefore, the message subscription can be flexibly canceled, and the user experience is improved.

In some embodiments, according to the content of the publishing service area name input by the user to the subscription record in the subscription list of the subscription service area, the content of the original publishing service area domain name in the subscription record is updated to the content of the publishing service area domain name in the subscription record, and the content of the publishing service area domain name in the subscription record is updated to the input content of the publishing service area name.

For example: because of the adjustment of business or function, the TopicName message originally provided by the area Domain2 subscribed by the area Domain1 is provided by the area Domain3 instead, and then an operator changes the subscription record in the subscription list of the area Domain1, changes the original subscription record [ TopicName, domain2, NULL, clientID ] into [ TopicName, domain3, domain2, clientID ], and after the change is completed, the information catalog of the area Domain1 sends a message cross-regional service notifying the area Domain 1.

And if the message cross-regional service of the subscription service region inquires the subscription record of which the message subject name and the domain name of the publishing service region are consistent with the updated message subject name and the original publishing service region name in the subscription list of the subscription service region, stopping operation, and finishing cross-regional message unsubscribing.

And if the message cross-regional service of the subscription service area does not inquire the subscription record of which the message subject names and the domain names of the publishing service areas are consistent with the message subject names and the original publishing service area names of the updated subscription record in the subscription list of the subscription service area, canceling subscribing the message corresponding to the message subject names in the updated subscription record in the updated original publishing service area. It is known that the specific operation is similar to the above-mentioned unsubscribing operation, and will not be described herein.

And if the message cross-regional service of the subscription service region inquires the subscription record of which the message subject names and the domain names of the publishing service regions are consistent with the updated message subject names and the updated publishing service region names in the subscription list of the subscription service region, the cross-regional message subscription is completed.

And if the message cross-regional service of the subscription service region does not inquire the subscription record of which the message subject names and the domain names of the publishing service regions are consistent with the message subject names and the publishing service region names of the updated subscription record in the subscription list of the subscription service region, subscribing the message corresponding to the message subject names in the updated subscription record in the updated publishing service region. It is known that the specific operation is similar to the subscription operation described above, and will not be described herein.

Therefore, the message publishing area can be changed under the condition that the code is not modified, and the flexibility of message subscription in a cross-regional environment is improved.

The message interaction method provided by the present disclosure may be described in detail below with reference to fig. 3, which is specifically as follows:

as shown in fig. 3, the following four service areas are included: the fixed service area D1, the maneuvering service area D2, the maneuvering service area D3 and the fixed service area D4 are formed by relying on the area D4.

The following example is completed based on fig. 3:

example 1: the business service a of the area D1 subscribes to the message D4.Material of the area D4;

example 2: the business service E of the area D1 subscribes to the message D4.Material of the area D4;

example 3: the business service C of the area D3 subscribes to the message D4.Material of the area D4;

example 4: the business service D of the area D4 issues a message Material;

example 5: the business service a of the area D1 unsubscribes from the message D4.Material of the area D4;

example 6: the business service E of the area D1 unsubscribes from the message D4.Material of the area D4;

example 7: the business service C of the area D3 unsubscribes from the message D4.Material of the area D4;

example 8: business service a of zone D1 subscribes to message D2. Signalization of zone D2;

Example 9: the motoring service area function is adjusted, and the Sitution message originally provided by the area D2 is now provided by the area D3;

example 10: the business service C of the area D3 issues a message Sitution;

example 11: the business service a of the area D1 is unsubscribed from D2. Site.

First, a pre-operation is performed, specifically as follows:

and D1, D2, D3 and D4 service areas are opened, and the domain name and the cross-regional gateway external address of each area are shown in table 1.

TABLE 1

DomainName	Address
		D1	10.10.10.1:9001
D2	10.10.10.2:9001
		D3	10.10.10.3:9001
D4	10.10.10.4:9001

The operator establishes external addresses of message cross-regional processing services in the respective regional areas on the cross-regional gateways corresponding to the areas D1, D2, D3 and D4, wherein the external addresses are respectively as follows:

region D1:10.10.1:9001/Msg- (21.21.21.3:8003);

region D2:10.10.2:9001/Msg- (22.22.22.3:8003);

region D3:10.10.10.3:9001/Msg- (23.23.23.3:8003);

region D4:10.10.4:9001/Msg- (24.24.24.3:8003).

The operator registers the above address in the whole area information directory as shown in table 2.

TABLE 2

ServiceName	Address
		D1Msg	10.10.10.1:9001/Msg
D2Msg	10.10.10.2:9001/Msg
		D3Msg	10.10.10.3:9001/Msg
D4Msg	10.10.10.4:9001/Msg

And an operator establishes a full-area information directory external mapping address of 10.10.10.4:9001/glonnfoaddr- (24.24.24.5:8005) on the trans-regional gateway of the area D4.

The operator establishes address mapping to the whole-area information catalog 10.10.10.4:9001/glonnfoaddr on the cross-area gateways corresponding to the areas D1, D2 and D3, wherein the address mapping is respectively as follows:

Region D1:21.21.1:8001/glonnfoaddr- (10.10.10.4:9001/glonnfoaddr);

region D2:22.22.1:8001/glonnfoaddr- (10.10.10.4:9001/glonnfoaddr);

region D3:23.23.23.1:8001/glonfoadr- (10.10.10.4:9001/glonfoadd).

The operator registers the mapping address from the cross-regional gateway to the whole-region information catalog in the region on the information catalog of the region, and registers the address 24.24.24.5:8005 in the whole-region information catalog in the information catalog of the region D4; registration information on the area D1 is shown in table 2; the service name of the message cross-regional service addressing the full-regional information directory is fixed to GloInfoAddr.

In the message cross-regional service and the information directory of the present region, when the message cross-regional service of other regions is addressed, the message cross-regional service name is in the form of domainname+msg, for example, the service name of the message cross-regional service of the region D1 is "D1Msg".

Example 1: the business service a of the area D1 subscribes to the message D4.Material of the area D4, and is specifically implemented as follows:

the business service a of the area D1 initiates a subscription request for the message D4.Material through the embedded message client carrying the ClientID number ClientA.

The message client embedded in the business service A sends a subscription request of the message D4.Material to the message service end of the area D1 and the message cross-area service.

After the message cross-regional service of the region D1 receives the subscription request for the message D4.Material, the subscription request is written into the information directory of the region D1, as shown in table 3, the "Material" is written into the TopicName field of the subscription list, the "D4" is written into the publichdomain field, the "NULL" is written into the outpatient publichdomain field, and the "ClientA" is written into the ClientID field.

TABLE 3 Table 3

After the information catalog of the area D1 receives the subscription request, inquiring whether subscription records with TopicName field of 'Material' and public Domain field of 'D4' exist in a subscription list of the information catalog, and if yes, returning to '2'; otherwise, inquiring whether the address information of the inter-regional service D4Msg of the information of the region D4 exists in the inter-regional service address list of other region information of the information directory, if not, returning to the '0' and the full-region information directory address, otherwise, returning to the '1' and the address information of the inter-regional service D4Msg of the region D4.

And (3) when the message is set to be subscribed to the D4 message for the first time, the information of the information directory of the last step of area D1 returned to the message trans-regional service is '0' and the whole-region information directory address is '21.21.21.1:8001/glonnfoaddr'.

After the message cross-regional service of the region D1 receives the returned information of 0 and the whole region information directory address, the splicing region domain name D4 and Msg are the message cross-regional service name D4Msg of the region D4, and then the message cross-regional service carries the D4Msg to initiate access to the whole region information directory.

After the message cross-regional service access full-regional information directory of the region D1 is mapped to the internal address "21.21.21.1:8001/glonnfoaddr" of the cross-regional gateway of the region D1, the request is mapped to the external address "10.10.10.4:9001/glonnfoaddr" of the cross-regional gateway of the region D4, and the cross-regional gateway of the region D4 maps the external address to the internal address "24.24.24.5:8005" of the full-regional information directory in the region D4.

After the gateway mapping, the area D1 obtains the external address "10.10.10.4:9001/Msg" of the information cross-regional service of the area D4 on the cross-regional gateway of the area D4 from the whole-regional information directory of the area D4.

The message cross-regional service of the region D1 initiates a channel establishment request for the cross-regional gateway of the region, and the mapping from the inter-regional gateway internal address of the region D1 to the cross-regional gateway external address of the region D4 is established by the message cross-regional service of the region D4, wherein 21.21.21.1:8001/D4Msg < - >10.10.10.4:9001/Msg; (the trans-regional gateway has the capability to receive the channel setup request and correspondingly set up the address mapping channel).

The message cross-regional service of the region D1 writes the address into the other region message cross-regional service address list of the information catalog of the region, wherein the ServiceName field is written into "D4Msg", the InnerAddress field is written into the cross-regional gateway internal address of the region D1 "21.21.21.1:8001/D4Msg", and the OuterAddress field is written into the cross-regional gateway external address of the region D4 "10.10.10.4:9001/Msg"; (the cross-regional gateway external address "outeraddress" field is an optional field, and the address map is stored in the cross-regional gateway).

The message cross-regional service of the region D1 carries the domain name "D1" of the region, and the message cross-regional service of the message subject name "Material" of the region D4 to be subscribed initiates a message subscription request.

After the message cross-regional service of the region D4 receives the subscription request, the subscription request is written into the information directory of the region D4.

After receiving the subscription request, the information directory of the area D4 writes "Material" in the TopicName field and "D1" in the subsribedomain field in the release list.

After receiving the subscription request, the information catalog of the area D4 inquires whether other subscription requests of other areas to the message theme 'Material' in the publishing list, namely, publishing records, if yes, the value '1' is returned, and if not, the value '0' is returned; setting the information catalog of the area D4 to be that the information catalog of the area D4 receives a subscription request of the information theme 'Material' of the other area for the first time, and returning '0' to the information cross-area service of the area D4.

After receiving the return value of 0, the message cross-regional service of the region D4 initiates a subscription request of message topic of Material on the message service end of the region D4 through the embedded message client; thus, the complete service A is completed to subscribe the message with the message theme of "D4. Material".

Example 2: the business service E of the area D1 subscribes to the message D4.Material of the area D4, and is specifically implemented as follows:

the business service E of the area D1 initiates a subscription request to the message D4.Material through the message client carrying the ClientID number ClientE.

The message client embedded by the business service E sends a subscription request of the message D4.Material to the message service end of the area D1 and the message cross-area processing service.

After receiving the subscription request of the business service E to the message D4.Material, the message cross-regional service of the region D1 writes the subscription request into the information catalog of the region D1.

After receiving the subscription request, the information directory of the area D1 writes "Material" in the TopicName field of the subscription list, "D4" in the publichdomain field, "NULL" in the outpatindpublichdomain field, and "ClientE" in the ClientID field.

And then, the message with the TopicName field of 'Material' and the public Domain field of 'D4' is subscribed for the second time, and the information catalog of the area D1 is returned to the message cross-area service '2'.

After the message cross-regional service of the region D1 receives the information catalog return value of 2 of the region, representing that the region has initiated subscription record to the message Material of the region D4, no subsequent operation is performed; thus, the service E in the area D1 completes the subscription request to the message D4. Material.

Example 3: the business service C of the area D3 subscribes to the message D4.Material of the area D4, and is specifically implemented as follows:

the basic flow is similar to that of example 1 above, and the description is omitted here, if the setting area D3 is the message D4.Material of the first subscription area D4.

After receiving the subscription request, the information catalog of the area D4 inquires whether other subscription requests of other areas to the message theme 'Material' exist in the publishing list of the information catalog, if so, the value '1' is returned, and if not, the value '0' is returned; since the posting list in the information directory of the area D4 stores the posting record, which is the subscription request for the message D4.Material initiated by the area D1, the information directory of the area D4 returns to the message cross-area service "1" of the area D4.

After the message cross-regional service of the region D4 receives the return value of 1 of the information catalog of the region, the subscription request of the message service end of the region D4 for the message D4.Material is not required to be initiated; thus, the service C in the area D3 completes the subscription request to the message D4. Material.

Example 4: the business service D of the area D4 issues a message Material, which is specifically implemented as follows:

the business service D of the area D4 issues a message of which TopicName is 'Material' to a message service end of the area D4;

the message service end of the area D4 pushes the message whose TopicName is "Material" to the message cross-regional service of the area D4 (the message client embedded in the message cross-regional service pushed to the area D4 may be equivalent to the message client to a certain extent, which is a part of the message cross-regional service).

After receiving the message of TopicName as "Material" by the message cross-regional service of the region D4, correspondingly querying a release list in the information catalog of the region D4, and acquiring the substricbedomain information corresponding to TopicName as "Material" and "D3" in the release list; (as shown in Table 4).

TABLE 4 Table 4

Publication list	TopicName	SubscribeDomain
			Material	D1
	Material	D3

After the information directory of the area D4 is queried to the domain names "D1" and "D3" of the subscription service area, if the information directory of the area D4 has the message cross-area service addresses of the areas "D1" and "D3", returning [ "D1", "1" and the message cross-area service address of the area D1 ], [ "D3", "1" and the message cross-area service address of the area D3 ]; otherwise return [ "D1", "0", and full area information directory address ], [ "D3", "0", and full area information directory address ].

The information catalog of the area D4 is set to have the information cross-regional service addresses of the area D1 and the area D3, namely, the information returned to the information cross-regional service by the information catalog is [ "D1", "1", "24.24.1:8001/D1 Msg" ] [ "D3", "1", "24.24.24.1:8001/D3Msg" ].

After the information is acquired by the message cross-regional service of the region D4, the access to the message cross-regional service of the region D1 and the region D3 is initiated, and the message of which TopicName is "Material" is sent to the message cross-regional service of the corresponding region.

After the message cross-regional service of the region D1 receives the message, inquiring subscription records with TopicName as 'Material' and publichDomain as 'D4' in a subscription list of an information catalog of the region, returning OutdatedPublishDomain information, if the OutdatedPublishDomain information is 'NULL', indicating that the message Material returned by the region D4 has no original subscription region, the message cross-regional service of the region D1 issues the message Material to a message service end of the region D1, and then the message service end of the region D1 pushes the message to business services A and E of the region D1; the processing procedure of the region D3 is similar to that described above, and will not be described here again.

Example 5: the business service a of the area D1 unsubscribes from the message D4.Material of the area D4, concretely implemented as follows:

The business service a of the area D1 initiates an unsubscribe request to the message D4.Material to the message service side and the message cross-area service of the area D1 through the message client carrying the ClientID number ClientA.

After receiving the message unsubscribing request, the message cross-regional service of the region D1 inquires a subscription list of an information catalog of the region, inquires a subscription record of which TopicName is 'Material', clientID is 'ClientA', a public domain field or an original publishing region Outddiscloses public domain field is 'D4', and inquires a result of [ 'Material', 'D4', 'NULL', 'ClientA').

The message cross-regional service of the region D1 deletes the records in the subscription list of the information catalog of the region, and simultaneously inquires whether other subscription records with TopicName fields of 'Material' and public Domain fields of 'D4' exist in the subscription list, if yes, the value of '1' is returned, and if not, the value of '0' is returned; the return value in this example is "1".

After the message cross-regional service of the region D1 receives the return value "1", which represents that other business services in the region have subscription requests for the message D4.Material, the message cross-regional service of the region D1 does not perform subsequent operations.

Example 6: the service E of the area D1 unsubscribes from the message D4.Material of the area D4, concretely implemented as follows:

the business service E of the area D1 initiates an unsubscribe request for the message D4.Material to the message service end of the area D1 and the message cross-area service by the embedded message client carrying the ClientID number ClientE.

After receiving the message unsubscribe request, the message cross-regional service of the region D1 inquires a subscription list of an information catalog of the region, inquires subscription records of which TopicName is "Material", clientID is "ClientE", public domain field or Outde public domain field is "D4", and inquires results are [ "Material", "D4", "NULL", "ClientE" ].

Deleting the records in the subscription list through the regional service by the message of the region D1, and simultaneously inquiring whether other records with TopicName fields of 'Material' and public domain fields of 'D4' exist in the subscription list, if so, returning a value of '1', otherwise, returning to '0'; the return value in this example is "0".

After the message cross-regional service of the region D1 receives the return value of "0", which represents that no other service in the region has a subscription request for the message D4.Material, the message cross-regional service of the region D1 initiates an unsubscribe request for the message D4. Material.

After receiving the unsubscribe request of the message Material sent by the message cross-regional service of the region D1, the message cross-regional service of the region D4 inquires a release list of the information catalog of the region D4, and correspondingly deletes the release record.

The message cross-regional service of the region D4 inquires whether the release list of the region has other release records of the message Material at the same time, if so, the message cross-regional service returns to 1, otherwise, the message cross-regional service returns to 0; the return value in this example is "1".

After the message cross-regional service of the region D4 receives the return value "1", if there is a subscription request of other regions to the message Material in the release list of the region D4, the message cross-regional service of the region D4 does not perform subsequent operations.

Example 7: the business service C of the area D3 unsubscribes from the message D4.Material of the area D4; the method is concretely realized as follows:

the business service C of the area D3 initiates a subscription-canceling request to the message D4.Material; the subsequent flow is similar to example 6, except that the return value is "0" in this example.

After the message cross-regional service of the region D4 receives the return value of "0", if there is no subscription request of other regions to the message Material in the publishing list of the region D4, the message cross-regional service of the region D4 initiates a subscription cancellation request to the message Material by accessing the message service end of the region D4 through the embedded message client.

Example 8: the business service a of the area D1 subscribes to the message D2. Site of the area D2, and is specifically implemented as follows:

the message D2. Subscription flow of the business service a of the area D1 to the area D2 is similar to the subscription flow described above, and will not be repeated here.

Example 9: the motoring service area function is adjusted, and the Sitution message originally provided by the area D2 is now provided by the area D3, and the following specific implementation is realized:

the operator modifies [ "Sitution", "D2", "NULL", "ClientA" ] in the subscription list of the information directory of the area D1 to [ "Sitution", "D3", "D2", "ClientA" ], the message Sitution indicating the subscription of ClientA is originally provided by the area D2 and is now provided by the area D3 instead; after the modification is completed, the information directory of the area D1 transmits a message to the inter-area service (as shown in table 3) notifying the area D1.

After receiving the notification, the message cross-regional service of the region D1 inquires whether subscription records with TopicName field of "location" and publichDomain field of "D3" exist in the subscription list of the region D1, if yes, the value of "1" is returned, and if not, the value of "0" is returned; in this example, there are no other related records, and the return value of the information directory to the message cross-regional service is "0".

After receiving the return value of 0, the message cross-regional service of the region D1 represents that no other service in the region D1 currently initiates a message subscription request for the TopicName of the region D3, and the message cross-regional service of the region D1 carries the message subscription request for the region D3 initiated by the TopicName field with the message subscription information.

After receiving the subscription request, the message cross-regional service of the region D3 accesses the information directory of the region, and writes [ "location", "D1" ] in [ "TopicName", "subsribedomain" ] fields of the release list.

The operation of the message cross-regional service of the region D3 on the subscription request is similar to the foregoing example, and will not be repeated here.

Meanwhile, after receiving the notification, the message cross-regional service of the region D1 inquires whether a record with a TopicName field of "location" and a publichDomain field of "D2" exists in a subscription list of the information catalog of the region D1, if so, returns to "1", otherwise, returns to a value of "0"; in this example, there are no other related records, and the return value of the information directory to the message cross-regional service is "0".

After receiving the return value of "0", the message cross-regional service of the region D1 represents that no other service in the region D1 currently initiates a message subscription request for the TopicName of the region D2, and then the message cross-regional service of the region D1 carries the TopicName field to initiate a message unsubscribe request for the region D2.

After the inter-regional service receives the above-mentioned unsubscribe request, the subsequent operations are similar to the above-mentioned unsubscribe operation, and will not be repeated here.

Example 10: the business service C of the area D3 issues a message situtation, which is specifically implemented as follows:

the business service C of the area D3 issues a message to the message service through the embedded message client, and the message service pushes the message to the message client embedded by the message cross-regional service of the area D3.

After the message cross-regional service in the region D3 receives the message, it queries the record of TopicName being "location" in the distribution list of the information directory in the region, and the query result is [ "location", "D1" ] (as shown in table 5).

TABLE 5

Publication list	TopicName	SubscribeDomain
				Situation	D1

The message cross-domain service of the area D2 transmits a message site to the message cross-domain service of the area D1 according to the subscore domain field value "D1".

The message cross-regional service of the region D1 receives the message situtation sent by the region D3, queries the subscription record with TopicName "situtation" and publicishdomain "D3" in the subscription list of the information directory of the region, and returns an outpatiedpublicishdomain field value "D2".

After the message cross-regional service of the region D1 receives the return value "D2", the OutdatedPublishDomain value "D2" and the TopicName value "signalization" are concatenated to D2. Signalization.

The message cross-regional service of the region D1 issues a Sitution message received from the region D3 to a message service end of the region D1 by taking D2.Sitution as TopicName; the message server then pushes the message to the business service a of the area D1 by querying its subscription list.

Example 11: the business service a of the area D1 unsubscribes from D2. Site, which is specifically implemented as follows:

the business service A of the area D1 initiates an unsubscribe request of the message D2. Site through an embedded message client, and the message client sends the unsubscribe request to a message service end of the area D1 and the message cross-area service.

After the message cross-regional service of the region D1 receives the message unsubscribe request, the subscription list of the information catalogue of the region is queried through [ TopicName, clientID ] value [ "location", "ClientA" ], and public domain field or OutdutPublishDomain field value "D2", and the information catalogue returns [ PublishDomain, outdatedPublishDomain ] value [ "D3", "D2" ].

After the message cross-regional service of the region D1 receives the returned result, the outpatiedpublishdomain field is not null, and a message unsubscribe request of the message site of the region D3 is initiated.

After the message cross-regional service of the region D3 receives the above-mentioned unsubscribe request, the subsequent operations are similar to the related steps described above, and will not be repeated here.
