Abstract
Apparatus, and an associated method, for communicating short message service content to a short message service center. The address of an IP-SM-GW (Internet Protocol-Short Message-Gateway) defined in the 3GPP TS 23.204 is provided to user equipment and used to address an SIP request that contains encapsulated SMS content. The address is stored at the mobile station at a storage element, such as at a SIM card, UICC, or management object. A SIP request generator accesses the storage element and uses the address as the address of the SIP request. The SIP request also includes SMS content, in encapsulation, therein.
Claims23
Apparatus for a short message service capable communication device, said apparatus facilitating communication of a message by way of a network having network entities comprising at least a short message service center, said apparatus comprising:
- a device management provisioner configured to provision a storage element with an identifier that identifies a selected network entity of the network entities,
- the identifier identifying a network interworking unit when the network comprises an SMS over IP network and the identifier identifying the short message service center when the network comprises an all-IP network;
- and
- a session initiation protocol, SIP, Request generator adapted to receive the identifier stored at said storage element, said SIP Request generator configured to generate an SIP Request addressed with the identifier and the SIP Request having a short message service content encapsulated therein;
- the SIP Request, once addressed, permitting routing thereof to the short message service center.
A method in a short message capable communication device for facilitating communication of a message originated at the communication device, said method comprising:
- storing an identifier at the communication device, the identifier identifying a selected network entity, the identifier identifying a network interworking unit when the network comprises an SMS over IP network and the identifier identifying a short message service center when the network comprises an all-IP network;
- generating a session initiation protocol, SIP, Request addressed with the stored identifier;
- encapsulating a short message service content in the SIP Request;
- and
- transmitting the SIP Request addressed with the stored identifier.
A method in a communication network having network entities comprising a short message service center for facilitating communication of a message originated at a short message capable communication device, said method comprising the operations of:
- storing an identifier at the communication device, the identifier identifying a selected network entity of the network entities, the identifier identifying a network interworking unit when the network comprises an SMS over IP network and the identifier identifying a short message service center when the network comprises an all-IP network;
- generating a session initiation protocol, SIP, Request addressed with the stored identifier;
- encapsulating a short message service content in the SIP Request;
- and
- permitting the SIP Request addressed with the stored identifier to be routed to the short message service center.
Apparatus for a short-message service capable communication device to permit sending of a short message service message to a short message service center by way of an access independent network to which the short message service center is positioned in communication connectivity, said apparatus comprising:
- a SIP Request generator configured to generate an SIP Request having a short message service content encapsulated therein and to communicate the SIP Request routable, by way of the access independent network to the short message service center, the SIP Request having an identifier identifying a network interworking unit when the network comprises an SMS over IP network and the identifier identifying a short message service center when the network comprises an all-IP network.
