FIELD: physics; communication. ^ SUBSTANCE: present invention pertains to the method of retrieving and sending multimedia messages (MMS) using session initiating protocol (SIP). Proposed here is a method of retrieving an MMS message (N404) by an MMS user agent (180), comprising the following stages: generation of an MMS subscription request (M401); sending the MMS subscription request (M401) to an MMS server (130); reception of an MMS report (M405) on the MMS message (N404) from the MMS server (130); in reply to the MMS report (M405), generation of an MMS message select query (M409) for retrieving the above mentioned MMS message (N404); sending the above mentioned MMS message select query (M409) to the MMS server (130); reception of an MMS message select query (M411), containing the above mentioned MMS service; and in reply to the received MMS message select query (M411) from the MMS server (130), sending a confirmation (m413) to the MMS server (M130). The above mentioned an MMS subscription request (M401) is sent using the SIP SUBSCRIBE method. The above mentioned MMS report is received using the NOTIFY method. The MMS message select query (M409) is sent using the FETCH method and the above mentioned confirmation is sent using the INFORM method. ^ EFFECT: possibility of retrieving MMS messages using SIP. ^ 8 cl, 5 dwg |
