Aiming at the technical problems, the embodiment of the invention provides an offline message transmission method, which relates to an offline message batch issuing mode, in particular to: the terminal informs the server of the capability of receiving offline messages in batches when registering, the server detects that the terminal has a plurality of offline messages (including one-to-one messages and group chat messages), encodes the offline messages in batches and continuously sends the offline messages to the client through MSRP (Message Session Relay Protocol ) messages. When the multimedia messages are more, the message transmission efficiency can be obviously improved. Tests show that the optimized scheme has obvious reduction in the aspects of terminal power consumption, flow and transmission time.

The scheme provided by the embodiment of the invention mainly relates to:

the new feature tag is carried in a SIP (Session Initiation Protocol ) register message (i.e., the above-mentioned registration message) at the time of registration by the client (i.e., the above-mentioned terminal), so as to inform the server that the client has the optimized offline message receiving capability (i.e., the capability of receiving offline messages issued in batch).

The embodiment of the invention provides a REGISTER request example, which is specifically as follows:

a// SIP message header for initiating registration;

REGISTER sip:bj.ims.mnc000.mcc460.3gppnetwork.org SIP/2.0

after the client is online, an offline message session is created, and the offline message is packaged and issued in batches by the server, as shown in fig. 3, which includes:

step 31: the client sends a REGISTER message to the server to request registration;

step 32: the server replies a 200OK message to the client to inform the client of finishing registration;

step 33: the server sends an offline message issuing request INVITE (offlinemsg) to the client;

step 34: the client replies a 200OK message to the server to create an offline message session with the server;

step 351: the server sends MSRP Send information to the client to Send offline information 1-M to the client;

step 361: the client replies a 200OK message to the server to inform the server of successfully receiving the offline messages 1-M;

step 352: the server sends MSRP Send information to the client to Send offline information M+1 to M+N to the client;

step 362: the client replies a 200OK message to the server to inform the server of successfully receiving the offline messages M+1 to M+N;

step (transmission of remaining offline messages);

Step 37: the server sends BYE information to the client to inform the client that the offline information is sent completely;

step 38: the client replies a 200OK message to the server to notify the server that the BYE message was successfully received, and knows that the offline message transmission is finished (i.e., the offline message transmission flow is finished at this time).

(III) MSRP messages are encoded in MIME (Multipurpose Internet Mail Extensions ) types, and multiple offline messages may be separated by a separator.

In the MSRP message body, each offline message content is encoded, the following parameters are extended (see table below) to correspond to the important header field parameters in the original SIP message (in order for the client to be able to identify each offline message), and a shorthand parameter format (optional use when supported by the client) is provided to reduce the message body size:

for special Service messages such as burn after reading and public account, the X-Rcs-Service-Type can carry a plurality of mark parameters (see the following table) at the same time, so as to be "; "separate (e.g., send a text message of a public number account number, which would need to be carried: P; pub).

Character string	Shorthand	Description of the invention
			Pager	P	Page text message, receipt message
Large	L	Large text message
			File	F	File transfer
group-chat	gc	Group chat text message, group chat optimized notify message
			group-invite	gi	Offline group chat invitation
barCycle	bar	Burn after reading sign
			publicmsg	pub	Public account message sign

For group chat services (including Pager, large, file transmission and other services), an isfocus parameter (namely the group chat identifier sub-parameter) can be carried in the X-Rcs-From, and the group chat message and the one-to-one message are distinguished through the parameter; such as: X-Rcs-From: "sip:12520001XXXXXXXXXXXX@as1.gc.rcs.chinamobile.com"; isfocus.

Various offline messages are mixed (i.e. at least two types of messages are encoded in one MSRP message), such as a Pager Mode message, a Large Mode message, a file transfer message, and service types include 1-1 messages, group chat messages (including group chat messages, offline notifications, etc.).

(IV) offline message packing (batch) Transmission mechanism and examples

In the embodiment of the present invention, if an offline message is to be transmitted, the instant message server (i.e., the server) needs to perform capability negotiation with the receiver (i.e., the terminal) to determine whether the receiver has the capability of receiving the message.

The session is established by capability negotiation, specifically through SIP INVITE. An example of an offline message session creation INVITE request is as follows:

a// SIP message header for establishing a session;
