A messaging server improves interworking of the Group-chat feature (such as defined in Rich Communications Services (RCS)) with short message services such as SMS. It matches chat invitations in an effective manner. When an RCS-User invites an SMS-User to an RCS Group-chat session, the identification of the RCS-User in the Group-chat to the SMS-User is via the MSISDN of the RCS-User. Using the MSISDN of the RCS-User in the RCS Group-chat invitation to the SMS-User will provide a direct match with the RCS-User MSISDN in the address-book of the SMS-User and therefore provide immediate clarity from who this Group-chat invitation was received. The SMS-User can accept or reject the Group-chat invitation by returning the proper response as requested in the invitation.

Group messaging

The present disclosure provides a method of routing a short message to a user. According to the method, an SMSC sends a routing request to a HLR or HSS of the terminating user. The HLR or HSS has static provisioning settings for users and relays the request according to these settings. The HLR or HSS relays the request to the IP-SM-GW, which dynamically determines if the terminating user has attached to an IMS network and accordingly decides on onward routing of the message over circuit switched or IMS network elements. The present disclosure also provides a mobile network apparatus that is configured to perform the method.

Relating to messaging gateways

A communication network messaging server () and user devices () have control channels () to send and receive control data. The server sends to an originating device control data indicating recipient availability, status, and/or presence prior to the originating device sending a message. The server control channel () includes a multiplexer () for streaming between a user message channel and the control channel and maintains device registration data, status data, presence data, and user group management data. The server () enables end user initiated availability, status, and/or presence updates to be shared with the messaging network and with recipient devices via said control channel.
