Abstract

A method and an IP-SM-GW for providing an interworking service between CPM and SMS are provided. The method comprises the steps of receiving a chat session invitation, in a IP-SM-GW, the chat session invitation originating from a CPM UE and being sent toward an SMS enabled UE. Assigning an identifier with the chat session in the IP-SM-GW and sending an invitation acknowledgement from the IP-SM-GW to the CPM UE. Receiving a message containing data, within the chat session, in the IP-SM-GW, from the CPM UE and being sent to the SMS enabled UE, formatting the message into an SMS message, wherein the identifier assigned to the chat session is inserted as a sender of the SMS message to ensure that an SMS response is sent back to the IP-SM-GW and forwarding the formatted SMS message to the SMS enabled UE.

Claims

1. A method for Service-level Interworking where a Converged IP Messaging (CPM) User Equipment (UE) sends a chat session invitation to a Short Message Service (SMS) user, comprising the steps of:

a) the CPM UE registers to a Serving Call Session Control Function (S-CSCF) according to an IMS registration procedure;

b) the CPM UE sends a session invitation request for a chat session to the S-CSCF, using an appropriate SIP method;

c) the S-CSCF forwards the session invitation to an Internet Protocol Short Message Gateway (IP-SM-GW) based on stored initial Filter Criteria (iFC);

d) the IP-SM-GW performs service authorization based on stored subscriber data retrieved from a Home Location Register (HLR) or a Home Subscriber Server (HSS) at the time of the registration procedure and the IP-SM-GW checks whether a originating subscriber of the CPM UE is authorized to use the Service-level Interworking service;

e) if the originating subscriber of the CPM UE is authorized to use the Service-level Interworking service, the IP-SM-GW acknowledges the session invitation;

f) a session invitation acknowledgement is forwarded by the S-CSCF to the CPM UE;

g) a user of the CPM UE sends a message within the chat session containing data to the SMS user;

h) the IP-SM-GW transforms the message into a short message and sends the short message towards the SMS user.
