Abstract
It is disclosed methods, apparatuses, system and related computer program for handover procedures. The method comprises a network node verifying if a location area of a handover destination belongs to a zone wherein a subscriber is allowed to access services and based on such verification either successfully handing over a call or rejecting a handover request.
Claims10
A method comprising:
- storing a mapping of zone identities and location areas;
- receiving from a first mobile services switching center a handover requisition message for a subscriber at a second mobile services switching center, the message comprising information relating to a location area of a handover destination and comprising at least one of a list of zone identities indicating zones wherein the subscriber is allowed to access services and a list of zone identities indicating zones wherein the subscriber is not allowed to access services, wherein the handover requisition message is a request for handover of a service being provided by the second mobile services switching center to the first mobile services switching center so that the service can be provided by the first mobile services switching center;
- verifying by the second mobile services switching center if the location area of the handover destination belongs to a zone wherein the subscriber is allowed to access services;
- and
- sending a first resultant message and a second resultant message based on a result of the verifying by the second core network entity,
- wherein if the result of the verifying is positive, sending the first resultant message, and
- wherein if the result of the verifying is negative, sending the second resultant message.

A receiving mobile services switching center apparatus comprising:
- a processor;
- a receiver configured to receive a handover requisition message from a mobile services switching center, the mobile services switching center being an entity different from the receiving mobile services switching center apparatus, comprising information relating to a location area of handover destination for a subscriber and at least one of a list of zone identities indicating zones wherein the subscriber is allowed to access services and a list of zone identities indicating zones wherein the subscriber is not allowed to access services, wherein the handover requisition message is a request for handover of a service being provided by the mobile services switching center to the receiving mobile services switching center apparatus so that the service can be provided by the receiving mobile services switching center apparatus;
- a storage configured to store a mapping of zone identities and location areas;
- a verifier configured to verify if the subscriber is allowed access services in the location area of handover destination;
- and
- a transmitter configured to send a first resultant message and a second resultant message based on a result of the verifying in said verifier,
- wherein if the result of the verifying is positive, the transmitter is configured to send the first resultant message, and
- wherein if the result of the verifying is negative, the transmitter is configured to send the second resultant message.
5 more elements
A system comprising:
- a processor;
- a first mobile services switching center apparatus comprising a first receiver configured to receive a handover requisition message from a second mobile services switching center apparatus comprising information relating a location area of a handover destination for a subscriber and at least one of a list of zone identities indicating zones wherein the subscriber is allowed to access services and a list of zone identities indicating zones wherein the subscriber is not allowed to access services, a storage configured to store a mapping of zone entities and location areas, a verifier configured to verify if the subscriber is allowed access services in the location area of handover destination, and a first transmitter configured to send a first resultant message and a second resultant message based on a result of the verifying in the verifier;
- said system further comprising:
- a second mobile services switching center apparatus comprising a second transmitter configured to send the handover requisition message comprising an indication of zones wherein the subscriber is allowed to access services, wherein the handover requisition message is a request for handover of a service being provided by the second mobile services switching center apparatus to the first mobile services switching center apparatus so that the service can be provided by the first mobile services switching center apparatus,
- wherein if the result of the verifying is positive, the transmitter is configured to send the first resultant message, and
- wherein if the result of the verifying is negative, the transmitter is configured to send the second resultant message.

A computer program embodied on a non-transitory computer readable medium, the computer program, when executed by a processor, causes the processor to
- store a mapping of zone identities and location areas;
- receive from a first mobile services switching center a handover requisition message for a subscriber at a second mobile services switching center, the message comprising information relating to a location area of a handover destination and comprising at least one of a list of zone identities indicating zones wherein the subscriber is allowed to access services and a list of zone identities indicating zones wherein the subscriber is not allowed to access services, wherein the handover requisition message is a request for handover of a service being provided by the second mobile services switching center to the first mobile services switching center so that the service can be provided by the first mobile services switching center;
- verify by the second mobile services switching center if the location area of the handover destination belongs to a zone wherein the subscriber is allowed to access services;
- and
- send a first resultant message and a second resultant message based on a result of the verifying by the second core network entity,
- wherein if the result of the verifying is positive, the computer program, when executed by the processor, causes the processor to send the first resultant message, and
- wherein if the result of the verifying is negative, the computer program, when executed by the processor, causes the processor to send the second resultant message.
