Methods, servers and mobile stations are provided to allow a sender mobile station which has transmitted a message toward a recipient mobile station via a first protocol to be notified that the message has been delivered to the recipient mobile station via a different protocol. The sender mobile station may be notified that the message was delivered to the recipient mobile station via a different protocol method via a disposition notification message comprising an indication that the message was delivered to the recipient mobile station via a different protocol.

Method and system for reporting message disposition in a communication network

Systems and methods are disclosed herein that enable a client device to efficiently identify mailboxes containing objects of interest in a server-based message store. In some embodiments, a method of operation of a client device comprises sending a single request to a server for a list of mailboxes maintained by the server for a user that contain objects flagged with any of one or more flags specified in the single request. The method of operation of the client device further comprises, in response to the single request, receiving, from the server, the list of mailboxes maintained by the server for the user that contain objects flagged with any of the one or more flags specified in the single request. The method also comprises processing the list of mailboxes. In this manner, the client device is enabled to quickly and efficiently identify which mailboxes of the user contain objects of interest.

Managing specialized objects in a message store

Embodiments of the invention relates to methods, and apparatuses for exchanging the preferred MSRP chunk sizes between an end-point and a remote end-point, directly or via a server using SDP offer/answer mechanism. The preferred MSRP chunk size may be the maximum allowed MSRP chunk size for the end-point and may be determined in accordance with network/link conditions and/or internal configuration. The end-point uses its preferred MSRP chunk size and the received preferred MSRP chunk size of the remote end-point to determine the MSRP chunk size that will be used to segment the messages from the end-point to the remote-end-point over the MSRP session. The preferred MSRP chunk size can be renegotiated during an ongoing MSRP session.

Negotiation of message chunk size for message session relay protocol session

Method and gateway unit for registering a user terminal () of a multimedia subscriber being a subscriber of a circuit switched network (), in an IP multimedia system (IMS) network (). Registration in the IMS network () of a first contact address associated with a circuit switched communication capability of the user terminal () for regular communication purposes is used, as well as registration in the IMS network () of a second contact address associated with a circuit switched communication capability of the user terminal () for messaging purposes.

Method and system for message routing in IMS and circuit switched networks

A method in a first user terminal () for supporting provision of capabilities of the first user terminal to a second user terminal () is provided. The method comprises receipt () of a capability request from the second user terminal. Upon receipt of the capability request, filtering rules are used () on the capabilities of the first user terminal, wherein the filtering rules have been pre-configured for the first user terminal to control exposure of said capabilities. Thereafter a capability message is transmitted () to the second user terminal, wherein at least one of the capabilities of the first user terminal have been omitted from the capability message based on the filtering rules.

Method and user terminal for supporting provision of capabilities

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.

Method and internet protocol short message gateway (IP-SM-GW) for providing an interworking service between converged IP messaging (CPM) and short message service (SMS)

A method of transporting image or video information between end user terminals via a packet switched network whilst a circuit switched connection is established between the end users includes establishing a circuit switched connection between a plurality of end user terminals for carrying voice traffic. The method also includes using the. Message Session Relay Protocol (MSRP) to encapsulate image or video information transmitted between end user terminals via a packet switched network, where MSRP related traffic is routed between said end user terminals via one or more MSRP enabled nodes. Additionally, the method includes installing service policies into the or at least one MSRP node from a session initiation protocol (SIP) application server (AS) located in the control-plane of an IMS network and checking multimedia service requests against the installed policies to control end user terminal access to certain packet based services.

Exchange protocol for combinational multimedia services

A method of controlling subscriber access to SIP-based services facilitated by an IP Multimedia Subsystem. The method comprises defining at a Serving Call Session Control Function node at least one default screening trigger, and downloading from a Home Subscriber Subsystem, specific screening triggers allocated to at least certain subscribers. At the Serving Call Session Control Function node, at least certain SIP messages originating at subscriber terminals are intercepted and, for each intercepted message and in the absence of a matching specific screening trigger, the default trigger is activated so as to cause the SIP message to be forwarded to a specific SIP application service.

IMS subscriber access control

A communications network configuration for delivery of multimedia services comprises a packet network to which a plurality of terminal devices are connected, a service provider network for providing multimedia services to the terminal devices, a virtual circuit switched network intermediate the packet and service provider networks, and a gateway distributed over the circuit switched network. The distributed gateway comprises a client application unit interfacing the circuit switched network to said packet network and a virtual channel interface unit interfacing the circuit switched network to the service provider network. The client application unit binds logical channels for a multimedia call to association tags for respective virtual channels of the circuit switched network and forwards said association tags to the virtual interfacing unit. The interfacing unit assigns to the multimedia call one or more virtual channels associated with the association tags and informs the client application unit of channel numbers for the assigned channels to thereby complete set up of the multimedia call.
