Reporting terminal capabilities for supporting short message service
A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.
1. A method for operation in a network device, the method comprising:
receiving at least one Internet Protocol (IP)-based registration message from a first user equipment (UE) via a wireless local area network (WLAN), wherein the at least one IP-based registration message indicates support for short message reception and includes security association data, a cellular network identifier of the first UE, and an IP address of the first UE;
storing, in a database, the security association data of the first UE, the cellular network identifier of the first UE, and the IP address of the first UE; and
receiving, from a second UE, a request for sending a short message, wherein the request is an IP-based message and includes a cellular network identifier of the first UE.
2. The method according to claim 1 , further comprising:
receiving capability information of the first UE, wherein the capability information includes at least one of: available memory size, terminal type, screen size, and SIP support.
3. The method according to claim 1 , further comprising:
transmitting, to the first UE, the stored cellular network identifier of the second UE.
4. A network device comprising:
a receiver for receiving at least one Internet Protocol (IP)-based registration message from a first user equipment (UE) via a wireless local area network (WLAN), wherein the at least one IP-based registration message indicates support for short message reception and includes security association data, a cellular network identifier of the first UE, and an IP address of the first UE; and
a database for storing the security association data of the first UE, the cellular network identifier of the first UE, and the IP address of the first UE;
wherein the receiver is configured to receive, from a second UE, a request for sending a short message, wherein the request is an IP-based message and includes a cellular network identifier of the first UE.
5. The network device according to claim 4 , wherein the receiver is configured to receive capability information of the first UE, wherein the capability information includes at least one of: available memory size, terminal type, screen size, and SIP support.
6. The network device according to claim 4 , further comprising:
a transmitter configured to transmit, to the first UE, the stored cellular network identifier of the second UE.
