Brief description of the figures
Figures 1 and 3 depict a schematic flow diagram;
Figures 2 and 4 depict a schematic block diagram; and Figure 5 depicts a schematic sequence diagram.
Description of the embodiments
Figure 1 depicts a schematic flow diagram of a method to operate a subscription entity of a communications network. According to the step 102 a control message is determined, wherein the control message comprises at least one
identifier indicating a plurality of affected subscribers, and an operation type. According to a step 104 the control message is transmitted to a session control entity. The control message is for example based on the Diameter
Protocol and comprises a certain set of Attribute Value Pairs, AVPs . The control message allows to realize the following use cases with a reduced control overhead: Mass Barring, Mass Blocking, Mass Deregistration, Mass AMBR (aggregated maximum bitrate) Update with same value for VoLTE specific INTERNET APNs, Mass Deletion of expired subscription, Mass Update of charging server details, Mass Provisioning of Shared Ids, Mass Update of Display name for certain similar type of applications, Mass Update of emergency location information, Identifiers SWAP use-cases triggering multiple messages on affected interfaces, MONTE Event Administrations. According to a further example, a reference location information change triggers a
registration-Termination Request, RTR, from the
subscription entity. Due to RTR there can be service interruption to the end user. The proposed method
facilitates the triggering RTR and forces a data reload from a call session control function, CSCF, via a Server- Assignment-Request, SAR.
Figure 2 depicts schematically the subscription entity 200. The subscription entity 200 comprises a processor 202, a communication module 204, and a memory 206. The memory 206 is equipped with computer program code 208, which is configured to, with the at least one processor 202, and the at least one communication module 204 to cause the
subscription entity 202 to execute the steps described in this specification. The subscription entity 200 is
especially configured as a home subscriber server, HSS.
Figure 3 depicts a schematic flow diagram of a method to operate the session control entity. According to a step 302 a control message is received from the subscription entity, wherein the control message comprises at least one
identifier indicating the plurality of affected
subscribers, and the operation type. According to a step 304 a plurality of affected subscriptions are determined in dependence on the at least one identifier and in dependence on the operation type. The identifier identifies several subscribers and therefore identifies the subscriptions of the subscribers, for example of IMS, non3GPP, Evolved
Packet System, EPS, Internet of Things, IoT. The
determination of the plurality of affected subscriptions
comprises a creation, updating or deleting of
subscriptions .
Figure 4 depicts schematically the session control entity 400. The session control entity 400 comprises a processor 402, a communication module 404, and a memory 406. The memory 406 is equipped with computer program code 408, which is configured to, with the at least one processor 402, and the at least one communication module 404 to cause the subscription entity 402 to execute the steps described in this specification. The session control entity 400 is especially configured as a call session control function, CSCF, especially as a service call session control
function, S-CSCF. The S-CSCF (Service Call Session Control Function) is a central instance that controls the service request and the connection setup of a subscriber. The subscriber is logged into the IMS system via the S-CSCF.
The S-CSCF queries the subscriber profiles from the HSS to obtain information about the services and functions that become relevant for the subscriber. The S-CSCF then
controls the connection removal, monitors the connection and terminates the connection at the end. It also monitors the fee calculation for the subscriber.
Figure 5 depicts a schematic sequence diagram of a
communications network 500, especially of an IP multimedia subsystem, IMS. A network operator entity 502, for example of a network operator, determines a mass request MR
affecting a plurality of subscription records. For example the mass request MR indicates a plurality of subscription
records of subscribers who have not paid their bills in order to block the subscription of these plurality of subscribers. Upon receiving the mass request MR a
provisioning system 504 searches the subscriber database 506 via a database request DBR and a corresponding database answer DBA.
A load balancer 508 monitors the provisioning system 504 via monitoring message M. The provisioning system 504 provides identifiers in form of a list and the
corresponding operation type via a corresponding message MA to the load balancer 508 upon receiving the monitoring message M. The load balancer 508 decides to distribute the affected identifiers according to a first group message G1 to a first subscription entity 200 a and according to a second group message G2 to a second subscription entity 200B. This distribution decision can be made in dependence on a load of the session control entity 400 which is also termed more general as peer network entity. For example, the subscription entities 200A and 200B are configured according to the subscription entity 200 of the figure 2.
The session control entity 400 could be a session control function, S-CSCF, a mobile management entity, MME, a
Service Capability Exposure Function, SCEF, a Session
Management Function, SMF, an Access and Mobility Function, AMF, or an Autonomous System, AS. Therefore, the principles of the present description can be applied to Internet of Things, IoT, 5th generation wireless systems, 5G, Evolved Packet System , EPS, or an IP Multimedia Subsystem, IMS.
Each one of the subscription entities 200A, 200B determines the control message Cl, C2 according to the provided group message Gl, G2. The session control entity 400 receives each one of the control messages Cl, C2 from the
subscription entities 200A, 200B, which provides that each one of the control messages Cl, C2 can be handled
separately, for example by different processing resources and/or communication resources. For example, virtualized network functions are able to handle the received control messages Cl, C2 in order to determine a plurality of affected subscriptions in dependence on the at least one identifier and in dependence on the operation type. For example at least one identifier is mapped to a plurality of affected subscriptions of subscribers by a mapping scheme, and encoding technique or a regular expression pattern. The session control entity 400 is therefore able to identify the subscriptions affected by the received control message Cl, C2, respectively. Together with the operating type the session control entity 400 is able to determine the
plurality of affected subscriptions, wherein the
determination includes a creation, modification or a deletion of the affected subscriptions.
The number of control messages Cl, C2 being generated is determined by the load balancer 508, for example in
dependence on peer capacity or predetermined agreements, or learning peer dynamics. The corresponding information has to be propagated to the load balancer 508.
The control message Cl, C2 has the following format:
Optimized-Operation : = <AVP header: X Y>
{ Operation-Type }
{Affected-Identifiers }
* [AVP]
The {Operation-Type} AVP has at least one of the following contents :
Complete-Subscription-Deregistration ( 0 )
Complete-Subscription-Blocked ( 1 )
Complete-Subscription-Deletion (2 )
Data-Reload-Required (3)
Shared-Data-Change (4)
The {Affected-Identifiers} AVP has the following format:
Affected-Identifiers: = <AVP header: X Y>
* {User-Identity}
* [User-Name]
* [Identity-Server-Location]
If the User-Identity is marked as then the
determination affects all subscribers at the session control entity 400 .
The control message Cl, C2 are exemplified in the
following, wherein the operation type "2" indicates that the session control entity 400 deletes the subscriptions identified via the affected identifiers.
Cl: =
Operation-Type: 2
Affected- Identifiers
User-Identity user1@ operator . com
User-Identity user3 @ operator . com
User-Identity user7 @ operator . com
User-Identity user 9@ operator . com
User-Identity userl8@operator . com User-Identity user19@ operator . com
C2 : =
Operation-Type: 2
Affected- Identifiers
User-Identity user36@ operator com
User-Identity user38@operator com
User-Identity user29@ operator com
User-Identity user59@ operator com
In dependence on responses Rl, R2 the control entity 400 indicates the success or failure of the execution of the control messages Cl, C2 respectively. In case of failure, the subscription entities 200, 200 B can initiate a further iteration of transmission of control messages Cl, C2. The responses Rl, R2 are also propagated to the load balancer 508.
