Problems solved by technology

However, when the GSM / GPRS message service and the IP-based message service are interoperable, since there is no similar function in the IP-based message service, each segmented message can only be sent as an independent message to the IP-based message service. terminal, and the terminal with IP access does not have any indication to know that this message is a segmented message, so it can only be displayed to the user as an independent message. For the user, the same service as the existing message service cannot be obtained. The quality is therefore unacceptable, which in turn will affect the promotion and use of IP-based messaging services

Embodiment Construction

[0065] The use of the existing SIP protocol message, for the case that the length of the message content to be sent is too long and exceeds the maximum data transmission unit that can be transmitted by a SIP protocol message, it is often unnecessary to establish a session for this purpose. Using the MSRP protocol to transmit this larger message content, it can be transmitted in segments, so that the same purpose can be achieved, but the use of network resources is much less than the use of the session method to transmit, and it is still general in the network view Sending of SIP messages. In specific implementation, the message sending end in the SIP network of the present invention judges whether the sent message content needs to be transmitted in segments by analyzing the message content before sending the message content. In the prior art, if the length exceeds the MTU, the MSRP protocol is used for transmission. However, in message transmission, in some cases, such as the mess...

Abstract

This invention discloses a message transmission method including: a, a sending end carries with segment instruction information in a SIP message of a segment transferred message, b, the receiving end receives the message content transmitted by each SIP message in segment based on said segment instruction information. This invention also discloses another two methods for transmitting messages.

Description

Technical field [0001] The present invention relates to the technical field of message transmission. More specifically, the present invention relates to a method for message transmission in a network based on the Session Initiation Protocol (SIP). Background technique [0002] SIP is an IP telephony signaling protocol proposed by the Internet Engineering Task Force (IETF). As its name implies, SIP is used to initiate a session. It can control the establishment and termination of a multimedia session attended by one or more participants, and can dynamically adjust and modify session attributes, such as session bandwidth requirements and transmission media types (Voice, video, text, etc.), media encoding and decoding formats, support for multicast and unicast, etc. [0003] In a network based on the SIP protocol, the message content transmitted by the SIP protocol is usually not too long, but in actual use, the user may also transmit a relatively large message content to the other ...
