Methods, wireless communication device, IMS and OCS for sending information to communication network subscribers

A method performed by an Online Charging System (OCS) of a communication network, the method comprising:

• receiving, from an IP Multimedia System (IMS) information of a call initiated or received by a wireless communication device, the information comprising an ID indicative of a subscriber of the wireless communication device;
• checking, based on the ID indicative of the subscriber, whether the subscriber of the wireless communication device is subject to a notification picture, and
• when the subscriber of the wireless communication device is subject to a notification picture, sending, to the IMS, a pointer referring to the notification picture, the pointer being intended for the wireless communication device.

A method performed by a wireless communication device of a communication network for a call initiated or received by the wireless communication device, the method comprising:

• receiving, from an IMS of the communication network, a pointer referring to a notification picture, the pointer originating from an OCS of the communication network,
• downloading the notification picture using the received pointer, and
• displaying the downloaded notification picture.

An Online Charging System (OCS) operable in a communication network, the OCS comprising a processing circuitry and a memory, said memory containing instructions executable by said processing circuitry, whereby the OCS is configured to:

• receive, from an IP Multimedia System (IMS) information of a call initiated or received by a wireless communication device, the information comprising an ID indicative of a subscriber of the wireless communication device;
• check, based on the ID indicative of the subscriber, whether the subscriber of the wireless communication device is subject to a notification picture, and
• when the subscriber of the wireless communication device is subject to a notification picture, send, to the IMS, a pointer referring to the notification picture, the pointer being intended for the wireless communication device.

A wireless communication device, operable in a wireless communication network, the wireless communication device comprising a processing circuitry and a memory, said memory containing instructions executable by said processing circuitry, whereby the wireless communication device is configured to:

• receive, from an IMS of the communication network, a pointer referring to a notification picture, the pointer originating from an OCS of the communication network,
• download the notification picture using the received pointer, and
• display the downloaded notification picture.

A non-transitory computer readable storage medium storing a computer program comprising instructions, which, when executed by at least one processing circuitry of an OCS of a communication network, causes the OCS to perform the steps of:

• receiving, from an IP Multimedia System (IMS) information of a call initiated or received by a wireless communication device, the information comprising an ID indicative of a subscriber of the wireless communication device;
• checking, based on the ID indicative of the subscriber, whether the subscriber of the wireless communication device is subject to a notification picture, and
• when the subscriber of the wireless communication device is subject to a notification picture, sending, to the IMS, a pointer referring to the notification picture, the pointer being intended for the wireless communication device.
