Delivery report for text messages in SIP communications

摘要

Systems and methods are disclosed for providing a delivery status of a text message in a SIP response. In one embodiment, a text message system receives a SIP request from an entity in a packet-switched network, where the SIP request encapsulates a text message. The text message system determines a status for delivering the text message to a recipient, and generates a SIP response that includes a delivery status parameter for text messages. The text message system inserts the determined delivery status for the text message in the delivery status parameter of the SIP response, and transmits the SIP response to the entity over the packet-switched network.

主权项

1. A text message system comprising:
a network interface configured to receive a Session Initiation Protocol (SIP) request that encapsulates a text message from an entity in a packet-switched network; and a control system including a processor configured to generate a SIP response for the SIP request indicating a delivery status of the SIP request to the text message system as successful; the control system is further configured to determine a delivery status of the text message to a recipient; the control system is further configured to insert an indication of the delivery status of the text message in a delivery status parameter of the SIP response so that the SIP response reports both the delivery status of the SIP request to the text message system and the delivery status of the text message to the recipient, wherein the delivery status of the text message indicates a successfully delivery to the recipient or a failed delivery; the network interface is further configured to transmit the SIP response to the entity over the packet-switched network.
