As shown in fig. 2, the 3GPP (3 rd Generation Partnership Project) SMs protocol is divided into 3 parts from top to bottom, which are SM-AL (Short Message Application Layer), SM-TL (Short Message Transport Layer) and SM-RL (Short Message Relay Layer) in sequence. The CM-layer (Connection Management-layer) is responsible for establishing and managing connections based on GSM, UMTS, LTE, and NR bearers, and provides a uniform service interface to the SM-RL, so that the transmission process of an SM-RL layer packet (RPDU) is decoupled from specific mobile communication systems (2G, 3G,4G, and 5G) of an air interface. In addition, 3GPP introduced an IMS (IP Multimedia Subsystem) network, which in turn extends sms Service to IMS, which can be carried over a 3g,4g or 5G network.

As shown in fig. 3, a short Message relay layer (SM-RL) data packet is composed of an RP (Reply path) data header and an RP data part, where the RP data header includes two important fields, namely, MTI (Message Type Indicator) and MR (Message Reference). MTI denotes the message type, e.g., message type RP-DATA (MTI: 0) or RP-ACK (MTI: 3). MR may represent a one-to-one correspondence between RP-DATA and RP-ACK. The message sending end UE checks the MTI and the MR value, and the RP-DATA and the RP-ACK with the same MR value are judged to be the same group of request and response messages.

In summary, according to the current implementation manner of the 3GPP short message service, the SM-AL, SM-TL, and SM-RL in the conventional short message protocol part are completely independent of the bottom layer bearer (2G, 3G,4G, 5G, and IMS), and the transmission format and the transmission process of the short message data are consistent from 2G to 5G.

At the beginning of the birth of the short message service, the short message service is carried on a control channel SACCH or SDCCH of GSM. Because the bandwidth of the GSM control channel is low and the data transmission capacity is weak, the length of a single short message data part is set to be 140 bytes. As shown in fig. 4, when a long short message with a length greater than 140 bytes needs to be transmitted, the SM-TL divides the long text into several short message segments, and then the SM-RL layer at the UE side divides a long short message into two short message segments for transmission by using a stop-wait mode, which specifically includes:

step 401, a SM-RL entity at a UE side sends a first short message segment RP-DATA (MTI: 0, MR;

step 402, the CM entity at the UE side bears RP-DATA through CP-DATA and sends the RP-DATA to the network;

step 403, after receiving the CP-DATA sent by the UE, the CM entity on the network side sends the RP-DATA (MTI: 0, mr;

step 404, the network side CM entity sends CP-ACK to the UE side CM entity, responding to the CP-DATA in step 402;

step 405, the network side SM-RL entity sends RP-ACK (MTI: 3, MR;

step 406, the network side CM entity carries RP-ACK through CP-DATA and sends the RP-ACK to the UE;

step 407, after receiving the CP-DATA sent by the network, the CM entity at the UE side sends RP-ACK (MTI: 3, MR;

step 408, the CM entity at UE side sends CP-ACK to the CM entity at network side, responding to the CP-DATA in step 6;

in steps 409 to 416, and in steps 401 to 408, the UE sends the second short message segment RP-DATA (MTI: 0, MR.

The SMSoIP is defined in 3GPP, the UE can transmit the traditional short MESSAGE by using IMS network, the transmission process of the UE sending and receiving the SMSoIP long short MESSAGE is specified in the SMSoIP long short MESSAGE test case, as shown in fig. 5, the IMS long short MESSAGE sequentially transmits each segment of the long short MESSAGE by using stop mode through the SIP protocol MESSAGE, which specifically includes:

step 501, the SM-RL entity at the UE side sends RP-DATA (MTI: 0, MR;

step 502, the IMS entity at the UE side transmits RP-DATA of a first short MESSAGE segment to the IMS entity at the network side through a MESSAGE;

step 503, after receiving the MESSAGE, the IMS entity at the network side submits the RP-DATA of the first short MESSAGE segment to the SM-RL entity at the network side (MTI: 0, mr;

step 504, the network side IMS entity replies 202 Accepted, notifies the UE side IMS entity, and receives MESSAGE;

step 505, the network side SM-RL entity replies with RP-ACK (MTI: 3, MR;

step 506, the network side IMS entity transmits RP-ACK to the UE side IMS entity through MESSAGE;

step 507, the SM-RL entity at the UE side receives RP-ACK (MTI: 3, MR;

step 508, the IMS entity of UE side replies 200OK, notify the IMS entity of network side, receive the MESSAGE in step 506;

in steps 509 to 516, in the same steps 501 to 508, the ue sends a second short message fragment RP-DATA (MTI: 0, mr.

At the beginning of the conventional short message standard, the 3GPP is limited by the low bandwidth of GSM underlying transmission in the 2G era, and the short message data length is limited to 140 bytes. When the long short message is transmitted, the SM-RL entity adopts a stop-wait mode, and transmits the segmented RP-DATA of the long short message on the bottom layer bearing through the CM-repeater. As the mobile communication technology evolves from 2G to 5G, and an IMS network is introduced to carry a call and a short message service, the transmission rate of the bottom layer of the mobile communication is greatly increased, but in order to ensure the consistency of the short message service in providing services to the upper layer application, the SMSoIP function still maintains the SM-TL and SM-RL layers unchanged. Therefore, the current 3GPP protocol still transmits long short messages on 3G,4G, 5G and IMS bearers in a manner of segmenting the long short messages by 140 bytes, and the SM-RL entity transmits each short message segment through the IMS bearer in a stop-wait mode. The stop-wait mode transmission mode of the long short message segmentation greatly limits the transmission efficiency of the long short message and cannot exert the advantage of high bandwidth of 3G,4G, 5G and IMS.

According to an aspect of the present application, there is provided an information transmission method as shown in fig. 6, including:

s601, a first entity of the terminal equipment sends a plurality of information segments; wherein the plurality of information segments are obtained by dividing original information;

s602, a first entity of the terminal equipment receives a plurality of response messages; wherein different ones of the plurality of response messages correspond to different ones of the message segments.

According to another embodiment of the present application, there is provided an information transmission method as shown in fig. 7, including:

s701, a first entity of the network equipment receives a plurality of information segments; wherein the plurality of information segments are obtained by dividing original information;

s702, a first entity of the network equipment sends a plurality of response messages; wherein different ones of the plurality of response messages correspond to different ones of the message segments.

Here, the network device may refer to a gateway; specifically, the Gateway may be an IP-SM-GW (Internet Protocol-Short Message-Gateway).

The original information may be a short message to be sent of the terminal device, and more specifically, the short message to be sent is a long short message to be sent. The long short message may refer to a short message with a length greater than 140 bytes. The multiple information segments are obtained by segmenting a long short message to be sent; the plurality of information segments may specifically refer to two or more information segments, that is, the plurality of information segments refer to at least two information segments. Illustratively, the plurality of information segments may be referred to as a plurality of short message segments. Hereinafter, unless otherwise specified, the meaning of the information segment and the short message segment is the same, and the repeated description is not repeated.

The process of dividing the information to be sent into a plurality of short message segments (i.e. information segments) by the first entity of the terminal device may be based on a preset length, where the preset length may be set according to practical situations, for example, 70 bytes or 40 bytes or more or less, and is not exhaustive here. The specific division manner is not exhaustive.

The first entity of the terminal device sends a plurality of information segments, including: the first entity of the terminal equipment sends the plurality of information segments to the second entity of the terminal equipment respectively; and the second entity of the terminal equipment respectively sends the plurality of information segments to network equipment. A first entity of the network device receives a plurality of information segments, including: the first entity of the network device receives the plurality of information segments sent by the terminal device from the second entity of the network device.

The first entity of the terminal device may specifically refer to a Short Message Relay Layer (SM-RL) entity of the terminal device. The first entity of the network device refers to the SM-RL entity of the network device. The SM-RL may refer to a protocol layer in the 3GPP SMs, which has been described in detail in the foregoing embodiments, and will not be described repeatedly here. Hereinafter, unless otherwise specified, the first entity has the same meaning as the SM-RL entity, and a description thereof will not be repeated.

The second entity of the terminal device may specifically refer to an internet protocol Multimedia Subsystem (IMS) entity of the terminal device. The first entity of the network device refers to an IMS entity of the network device. In the following, unless otherwise specified, the second entity has the same meaning as the IMS entity, and will not be described repeatedly.

Wherein, the step of sending the plurality of information segments to the second entity of the terminal device by the first entity of the terminal device respectively means that: a first entity of the terminal equipment sequentially sends a plurality of information segments to a second entity according to the sequence of the information segments; or the first entity of the terminal equipment simultaneously sends the plurality of information segments to the second entity of the terminal equipment.

Based on the foregoing embodiment, it can be seen that the first entity of the terminal device may receive the multiple pieces of response information after completing sending the multiple pieces of information, and thus the terminal device does not need to wait for the response information of each piece of information in the process of sending the multiple pieces of information, so that the transmission time of the sent information may be shortened, and the transmission efficiency of the information may be improved.

In some possible embodiments, the sending, by the second entity of the terminal device, the plurality of information segments to the network device includes: the second entity of the terminal equipment determines a target information segment from one or more unsent information segments when one or more unsent information segments exist in the plurality of information segments; the second entity of the terminal equipment sends a target message carrying the target information segment to the network equipment; the second entity of the terminal equipment determines to finish sending the plurality of information segments under the condition that the second entity receives the confirmation message of the target message sent by the network equipment and no unsent information segment exists in the plurality of information segments; wherein the acknowledgement message of the target message is used for indicating that the network device receives the target message.

Optionally, in the plurality of information segments, each information segment may carry an order of the information segment in all the plurality of information segments, and the order may be characterized by a number, a sequence number, or the like; and/or the number of total information segments that may be carried in each information segment; and/or the number of information segments that may carry the entire information segment in a first information segment of the plurality of information segments. Correspondingly, the method for the first entity of the network device to determine whether the target information segment is the last information segment may include: the first entity of the network equipment acquires the number of the target information segment and the number of all the information segments from the target information segment, judges whether the number of the target information segment is equal to the number of all the information segments, if so, determines that the target information segment is the last information segment, otherwise, determines that the target information segment is not the last information segment.

Optionally, each information segment may also carry indication information; for example, the indication information may be a flag bit in an information segment, and if the value of the flag bit is a first value, it may indicate that the information segment is not a last information segment, and if the value of the flag bit is a second value, it may indicate that the information segment is a last information segment. Correspondingly, the method for the first entity of the network device to determine whether the target information segment is the last information segment may include: and the first entity of the network equipment acquires the value of the marking bit contained in the target information segment from the target information segment, judges whether the value of the marking bit is a second value or not, determines that the target information segment is the last information segment if the value of the marking bit is the second value, and otherwise determines that the target information segment is not the last information segment.

That is, in this embodiment, when the second entity of the terminal device and the second entity of the network device perform transmission of the target message and the acknowledgement message of the target message, an idle mode is adopted, that is, after one target message is sent, the acknowledgement message of the target message is received, and then the next target message is transmitted, and so on until transmission of all target messages is completed.

The target message and the acknowledgment message of the target message together constitute a transaction specified in SIP (Session initiation Protocol).

Unless otherwise stated, the values of MR, MR and MR are the same, and are not described again.

The jth response message refers to any one of multiple response messages, and because the multiple response messages are sent out sequentially and the processing for generating and sending one response message each time is the same, the details are not repeated. In addition, the number of the plurality of pieces of response information is the same as the number of the plurality of pieces of information.

The processing manner of the first entity of the network device may further include: and the first entity of the network equipment takes the corresponding relation value contained in the kth information segment as the corresponding relation value of the jth response information.

The processing at the first entity of the terminal device may further comprise: the first entity of the terminal device determines that the jth response information corresponds to the kth information segment based on the corresponding relationship value contained in each of the plurality of information segments and the corresponding relationship value contained in the jth response information; wherein, the information headers of different information segments contain different corresponding relation values; the kth information segment is one of the plurality of information segments, and k is a positive integer. Specifically, in the processing of the first entity of the terminal device, after receiving the jth response message, the first entity of the terminal device compares the jth response message with the corresponding relationship values of the multiple information segments one by one based on the corresponding relationship value included in the jth response message, and determines that the jth response message corresponds to the kth information segment when the corresponding relationship value included in the jth response message is the same as the kth information segment in the multiple information segments.

Here, k and j may be the same or different. That is, when the first entity of the network device generates the response information, the corresponding response information is not necessarily generated sequentially according to the sequence of the information segments. For example, the first response message generated by the first entity of the network device may be a response message corresponding to a second information segment of the plurality of information segments. However, since the response information needs to include a corresponding relationship value, which is the same as the corresponding relationship value included in the corresponding information segment, no matter whether the sequence of the response information generated by the first entity of the network device is the same as the sequence of receiving or sending the information segment, the first entity of the terminal device may determine the information segment corresponding to the response information based on the corresponding relationship value in the response information, that is, the terminal device may determine which information segment has received the corresponding response information.

For example, a first entity of the network device receives a first information segment and a second information segment, respectively, where an MR value in the first information segment is 1, and an MR value in the second information segment is 2; the first entity of the network device first generates a first response message, which is a response message of the second message segment, and the MR value in the first response message is 2. When the first entity of the terminal device may receive the first response message, it is determined that the first response message is the response message corresponding to the second message segment based on the MR value in the first response message being 2.

It should be further noted that, the second entity of the foregoing network device sends the jth reply message, and the second entity of the terminal device sends the jth reply acknowledgement message, which may also form a transaction specified in SIP (Session initiation Protocol).

In addition, in the plurality of information segments and the plurality of response information, a type indication may be carried in addition to the correspondence value. Specifically, each of the aforementioned information segments may be a data packet (i.e., SM-RL layer data packet), and similarly, each of the response messages is also a data packet (i.e., SM-RL layer data packet). Wherein, the corresponding relation value and type indication of each information segment are carried in the data head of the information segment; the corresponding relationship value and type indication for each response message is also carried in the header of the response message. In addition, each information segment further includes a data portion (or referred to as RP data portion), which may carry specific segment content or segment data; each response message may also contain a data portion, which may carry specific response content.

The value (or value) of the type indication may represent the type of information content; for example, the value of the type indicator is a third value for indicating that the type of the information content is a data type, and the value of the type indicator is a fourth value for indicating that the type of the information content is a response type; the third value is different from the fourth value, for example, the third value is 0, the fourth value is 3, or the third value and the fourth value may have other values, which are within the protection range of the embodiment as long as the third value and the fourth value are different. Illustratively, the type indication may specifically be MTI; for example, if the MTI value in the header of a DATA packet is 0, it indicates that the DATA packet is an information segment (which may be denoted as RP-DATA); for another example, if the MTI value in the header of a data packet is 3, the data packet is a response message (which may be denoted as RP-ACK).

The correspondence value may be MR; the MR value (or value) is used to identify the same set of RP-DATA and RP-ACK, i.e., the same set of RP-DATA and RP-ACK have the same MR value; the MR has already been described in detail in the foregoing embodiments, and will not be described repeatedly.

For example, when an SM-RL entity of a terminal device sends a DATA packet, the DATA header of the DATA packet carries an MTI and the value is 0, so as to indicate that the type of the information content of the DATA packet is a DATA type, that is, to indicate that the DATA packet is specifically an information segment (that is, an RP-DATA); in addition, the data header of the data message carries the MR and sets the value of the MR to be 1, so that the network device uses the value of the MR to represent the response information corresponding to the information segment. Correspondingly, when receiving a DATA message, the SM-RL entity of the network device may determine that the received DATA message is an information segment (i.e., RP-DATA) by analyzing the value of the MTI of the DATA header of the DATA message to be 0, and analyze the DATA header of the DATA message to obtain the value of the MR to be 1; when the SM-RL entity of the network device generates the response information of the information segment, a data packet is also generated, the data packet is represented as a response information (i.e., RP-ACK) by the MTI value carried in the data header of the data packet being 3, and the information segment corresponding to the response information is represented by the MR value carried in the data header of the data packet being 1.

In summary, by adopting the above embodiment, the first entity of the terminal device can concurrently transmit a plurality of information segments, thereby ensuring the information transmission efficiency. And the terminal equipment can determine the corresponding relation between the response information and the information segments through the corresponding relation value, so that the problem of disorder of the response information possibly generated by the concurrence of the information segments can be solved on the basis of ensuring the transmission efficiency. Specifically, by analyzing the SM-RL protocol, the SM-RL layer already supports the concurrent mode transmission of the information segments (namely, RP-DATA), so that the stop-wait mode of the transmission process of the SM-RL layer can be improved into the concurrent mode when a long short message is sent, so as to improve the transmission efficiency. When the SM-RL entity transmits the information segments in a concurrent mode, the information segments (namely, RP-DATA) and the response information (namely, RP-ACK) are matched by combining the MTI and the MR fields, so that the disorder problem in the transmission process can be avoided.

With reference to fig. 8, the terminal device is a UE, the network device is an IP-SM-GW, the first entity is an SM-RL entity (denoted as SM-RL in fig. 8), the second entity is an IMS entity (denoted as IMS in fig. 8), the information segment is a short message segment RP-DATA, the response information is RP-ACK, the type indication is MTI, and the relationship value is MR, which are taken as examples, the foregoing embodiment is exemplarily described:

step 801, the SM-RL entity at the UE side sends a first short message segment RP-DATA1 (MTI: 0, MR.

And step 802, the SM-RL entity on the UE side sends a second short message segment RP-DATA2 (MTI: 0, MR.

The foregoing steps 801 and 802 may be executed sequentially or concurrently, and are within the protection scope of the present embodiment. In addition, the process of the SM-RL entity sending the short message segment in steps 801 and 802 may be referred to as SMs-SUBMIT. The description of the aforementioned MTI and MR is the same as the aforementioned embodiment, and is not repeated.

Step 803, the UE side IMS entity sends a first short MESSAGE segment RP-DATA1 (MTI: 0, MR.

Here, MESSAGE1 may be a target MESSAGE in the foregoing embodiment; that is, the UE-side IMS entity determines the current target short MESSAGE segment (for example, selected as RP-DATA1 this time) from the two short MESSAGE segments in sequence, and sends the target short MESSAGE segment carried in MESSAGE1 (i.e., target MESSAGE 1) to the network-side IMS entity.

Step 804, after receiving the MESSAGE1, the network side IMS entity submits the first short MESSAGE segment RP-DATA1 (MTI: 0, mr.

Step 805, the network side IMS entity replies 202 Accepted, and notifies the UE side IMS entity to receive MESSAGE1 in step 804. Wherein 202 Accepted is the acknowledgement MESSAGE of the MESSAGE1 (i.e. the target MESSAGE 1).

The execution sequence of the step 804 and the step 805 may not be sequential, and the step 804 may be executed first and then the step 805 may be executed; alternatively, step 805 may be performed first and then step 804 may be performed; alternatively, step 804 and step 805 may be executed simultaneously, and are within the protection scope of the present embodiment.

In step 806, the UE side IMS entity sends a second short MESSAGE fragment RP-DATA2 (MTI: 0, MR.

In step 807, after receiving the MESSAGE2, the IMS entity on the network side submits RP-DATA2 (MTI: 0, mr.

Step 808, the network side IMS entity replies 202 Accepted, and notifies the UE side IMS entity to receive MESSAGE2.

The detailed description of the steps 806 to 808 is similar to the steps 803 to 805, and thus is not repeated herein.

Step 809, the network side SM-RL entity replies with RP-ACK2 (MTI: 3, MR.

In the step, the network side processes the RP-DATA1 and the RP-DATA2 to cause the RP-ACK disorder of the reply, wherein the RP-ACK2 is response information aiming at the second short message segment RP-DATA2 (MTI is 0, MR is 1) in the step 802, and therefore the value of the MR carried in the RP-DATA2 is the same as that of the RP-DATA 2.

In step 810, the network side IMS entity transmits RP-ACK2 (MTI: 3, MR 1. MESSAGE3 is the reply MESSAGE in the previous embodiment. Namely, the network side IMS entity carries RP-ACK2 in MESSAGE3.

In step 811, the SM-RL entity on the UE side receives RP-ACK2 (MTI: 3, MR.

In this step, the SM-RL entity on the UE side can know that the current RP-ACK2 is response information for RP-DATA2 (MTI: 0, MR 1) in step 802 based on the value of MR. Since the same MR value as RP-DATA2 is carried in RP-ACK2, the UE side SM-RL entity can determine the information segment (or short message segment) corresponding to each response message even if the response is out of order.

Step 812, the ue side IMS entity replies 200OK to notify the network side IMS entity, and receives MESSAGE3 in step 810. Here, "200OK" is the reply confirmation message in the foregoing embodiment.

The execution sequence of the step 811 and the step 812 may not be sequential, and the step 811 may be executed first and then the step 812 may be executed; alternatively, step 812 may be performed first and then step 811 may be performed; alternatively, step 811 and step 812 may be performed simultaneously, and both are within the scope of the present embodiment.

In step 813, the network side SM-RL entity replies with RP-ACK1 (MTI: 3, MR.

In the step, the network side processes RP-DATA1 and RP-DATA2 to cause the returned RP-ACK out of order, wherein the RP-ACK1 is response information aiming at RP-DATA1 (MTI is 0, MR is 0), so that the value of the MR carried in the RP-DATA1 is the same as that of the RP-DATA 1.

In step 814, the network side IMS entity transmits RP-ACK1 (MTI is 3, mr is 0) to the UE side IMS entity through MESSAGE4. Namely, the network side IMS entity carries RP-ACK1 in MESSAGE4.

Step 815, the SM-RL entity on the UE side receives RP-ACK1 (MTI is 3, MR is 0) on the network side.

In this step, the SM-RL entity on the UE side can know that the current RP-ACK1 is response information for RP-DATA1 (MTI: 0, MR. Since the same MR value as RP-DATA1 is carried in RP-ACK1, the UE side SM-RL entity can determine the information segment (or short message segment) corresponding to each response message even if the response is out of order.

Step 816, the ue side IMS entity replies 200OK to notify the network side IMS entity, and receives MESSAGE4 in step 814. Here, "200OK" is the reply confirmation message in the foregoing embodiment.

The detailed description of the foregoing steps 813-816 is similar to the detailed description of the steps 809-812, and is not repeated.

It should be noted that the transmission process of RP-ACK1 or RP-ACK2 in steps 809 to 815 may also be referred to as SMS-SUBMIT-STATUS interaction process.

In some possible embodiments, the sending, by the second entity of the terminal device, the plurality of information segments to the network device includes: the second entity of the terminal equipment sends a plurality of messages to the network equipment; wherein different ones of the plurality of messages carry different ones of the plurality of information segments; a second entity of the terminal equipment receives a plurality of confirmation messages sent by the network equipment; wherein each of the plurality of acknowledgement messages is used to indicate that the network device received the corresponding message.

The first entity of the network device receiving the plurality of information segments sent by the terminal device from the second entity of the network device, including: when a second entity of the network device receives a plurality of messages sent by the terminal device, a first entity of the network device receives information segments carried by each message in the plurality of messages sent by the second entity of the network device, and the second entity of the network device sends a plurality of confirmation messages to the terminal device; wherein each of the plurality of acknowledgement messages is used to indicate that the network device received the corresponding message.

The present embodiment is different from the foregoing embodiment in that, in the foregoing embodiment, the second entity of the terminal device receives the acknowledgment message of the message each time the second entity sends one message, and then sends the next message; in this embodiment, the second entity of the terminal device also sends all the plurality of messages, that is, the network device sends the plurality of acknowledgement messages after receiving all the plurality of messages.

The processing by the second entity of the network device may further comprise: judging whether the information segment carried in the currently received message is the last information segment or not, and if the information segment is the last information segment, determining that the receiving of a plurality of messages is finished; otherwise, it may continue to wait for the next message to be received from the second entity of the terminal device. The manner of determining whether the information segment is the last information segment is similar to the foregoing embodiment, and a repetitive description will not be made.

The processing of the second entity of the terminal device further comprises: and the second entity of the terminal equipment determines the reference identifier of each message based on the first parameter carried by each message in the plurality of messages. The method further comprises the following steps: the second entity of the terminal equipment determines the reference identifier of each acknowledgement message based on the second parameter carried by each acknowledgement message in the plurality of acknowledgement messages; and the second entity of the terminal equipment determines the message corresponding to each confirmation message based on the reference identifier of each confirmation message and the reference identifier of each message.

The processing of the second entity of the network device further comprises: the second entity of the network equipment determines a second parameter carried by the confirmation message of each message based on the first parameter carried by each message; the first parameter is used for determining a reference identifier of each message, and the second parameter is used for determining a reference identifier of an acknowledgement message of each message.

Each of the aforementioned acknowledgement messages together with its corresponding message constitutes a transaction in SIP. The reference identifier may be denoted as Transaction ID.

The number of the first parameters carried by each message may be one or more, and it should be understood that the first parameters carried by different messages are the same, but values of the first parameters carried by different messages are different. The second parameter carried by the acknowledgement message of each message is the same as the first parameter carried by the message, and the value of the second parameter is the same as that of the first parameter.

The determining, by the second entity of the network device, the second parameter carried by the acknowledgment message of each message based on the first parameter carried by each message may specifically be: when a second entity of the network device generates an acknowledgment message of a message, the first parameter and the value of the first parameter carried by the message are used as the value of a second parameter and a value of a second parameter carried by the acknowledgment message of the message. Illustratively, any one message is assumed to be a message1, and the first parameter that can be carried by the message1 includes at least one of the following: branch parameter 1 and cseq (command sequence number) 1 in the Via header field. The second parameter carried by the acknowledgement message of the message1 also includes at least one of the following: branch parameter 1 and cseq (command sequence number) 1 in the Via header field. The Via header field represents a transmission device for transaction transmission and an address for sending back a response; the branch parameter is used for representing the transaction, namely the branch parameter values of the same transaction are the same; cseq is used to distinguish between transactions and sequences as transactions.

The manner of determining the reference identifier of each message based on the first parameter carried by each message in the plurality of messages by the second entity of the terminal device may be: and the second entity of the terminal equipment generates the reference identification of the message based on the branch parameter and cseq in the Via header field of each message. The specific way of generating the reference identifier is not limited in this embodiment. The manner of determining the reference identifier of each acknowledgment message by the second entity of the terminal device based on the second parameter carried in each acknowledgment message of the multiple acknowledgment messages may also be: and the second entity of the terminal equipment generates a reference identifier of the confirmation message based on the branch parameter and cseq in the Via header field of each confirmation message in the plurality of confirmation messages.

The determining, by the second entity of the terminal device, the message corresponding to each acknowledgment message based on the reference identifier of each acknowledgment message and the reference identifier of each message may refer to: and the second entity of the terminal equipment compares the reference identifier of each confirmation message with the reference identifier of each message, matches the messages with the same reference identifier with the confirmation messages and obtains the message corresponding to each confirmation message.

When the second entity of the network device generates the acknowledgement messages, the corresponding acknowledgement messages are not necessarily generated in sequence according to the order of the messages. For example, the first acknowledgement message generated by the second entity of the network device may be an acknowledgement message corresponding to the second message of the plurality of messages. However, no matter whether the order of the confirmation messages generated by the second entity of the network equipment is correct or not, because the reference identifications of a pair of messages and the confirmation messages are the same, the corresponding messages can be determined by calculating the reference identifications of the confirmation messages, and thus the problem of message disorder can be solved.

For example, when the second entity of the terminal device sends the message1, the reference identifier Transaction ID obtained according to the first parameter carried in the message1 is equal to 1, and when the second entity of the terminal device sends the message2, the reference identifier Transaction ID is determined to be equal to 2 according to the first parameter carried in the message2. If a second entity of the network device first sends the acknowledgement message of the message2, the second parameter and the value thereof carried in the acknowledgement message are the same as the first parameter and the value thereof of the message2, and then when sending the acknowledgement message of the message1, the second parameter and the value thereof carried in the acknowledgement message are the same as the first parameter and the value thereof of the message1. Correspondingly, under the condition that the second entity of the terminal equipment receives the first confirmation message, the second entity obtains the second parameter carried by the first confirmation message and the value thereof from the first confirmation message, and calculates to obtain the reference identifier of the confirmation message, namely the Transaction ID is equal to 2; the confirmation message can be determined to be the confirmation message corresponding to the message1 based on the Transaction ID being equal to 2; the processing of the second acknowledgment message is the same as that of the first acknowledgment message, and is not described in detail. It should be understood that the above only takes two messages and their corresponding acknowledgement messages as examples, and there may be more messages and their corresponding acknowledgement messages in actual processing, and the processing manner is similar to the foregoing examples, but is not exhaustive.

The first entity of the network device sends a plurality of response messages, including: a first entity of the network device sending the plurality of response messages to a second entity of the network device; a second entity of the network equipment sends a plurality of reply messages to the terminal equipment; each reply message in the plurality of reply messages carries response information, and different reply messages carry different response information; a second entity of the network equipment receives a plurality of reply confirmation messages sent by the terminal equipment; wherein each reply acknowledgement message in the plurality of reply acknowledgement messages is used for indicating that the terminal device receives the corresponding reply message.

The first entity of the terminal equipment receives a plurality of response messages, including: when a second entity of the terminal device receives a plurality of reply messages sent by the network device, a first entity of the terminal device receives response information carried by each reply message in the plurality of reply messages sent by the second entity of the terminal device, and the second entity of the terminal device sends the plurality of reply confirmation messages to the network device; wherein each reply acknowledgement message in the plurality of reply acknowledgement messages is used for indicating that the second entity of the terminal device receives the corresponding reply message.

Wherein each of the plurality of information segments comprises a corresponding relationship value; wherein, the corresponding relation values contained in the information headers of different information segments are different. In a preferred example, the corresponding relation value may specifically be an MR value in a 3GPP short message protocol.

Each piece of response information in the plurality of pieces of response information comprises a corresponding relation value, the corresponding relation values contained in different pieces of response information are different, and each piece of response information is the same as the corresponding relation value contained in the corresponding information segment.

The processing at the first entity of the terminal device may further comprise: the first entity of the terminal equipment determines the information segment corresponding to each piece of response information based on the corresponding relation value contained in each piece of information in the plurality of pieces of information and the corresponding relation value contained in each piece of response information in the plurality of pieces of response information; wherein, the corresponding relation values contained in different information segments are different; the corresponding relation values contained in different response messages are different; each response message has the same corresponding relationship value as the corresponding message segment.

That is, when the first entity of the network device generates the response information, the corresponding response information is not necessarily generated sequentially according to the sequence of the information segments. For example, the first response message generated by the first entity of the network device may be a response message corresponding to a second information segment of the plurality of information segments. However, regardless of whether the order of the response information generated by the first entity of the network device is correct, the response information needs to include a correspondence value that is the same as the correspondence value contained in its corresponding information segment. For example, a first entity of the network device receives a first information segment and a second information segment, respectively, where an MR value in the first information segment is 1 and an MR value in the second information segment is 2; the first entity of the network device first generates a first response message, which is a response message of the second message segment, and the MR value in the first response message is 2. Correspondingly, in the processing of the first entity of the terminal device, after receiving each piece of response information, the first entity of the terminal device determines an information segment corresponding to the response information, where the information segment corresponds to the corresponding relationship value included in the response information.

The processing of the second entity of the terminal device further comprises: the second entity of the terminal equipment determines a fourth parameter carried by each reply confirmation message based on the third parameter carried by each reply message; wherein the third parameter is used to determine a reference identifier of each reply message, and the fourth parameter is used to determine a reference identifier of each reply acknowledgement message.

The processing by the second entity of the network device further comprises: and the second entity of the network equipment determines the reference identifier of each reply message based on the third parameter carried by each reply message in the plurality of reply messages. The method further comprises the following steps: the second entity of the network device determines a reference identifier of each reply acknowledgement message based on a fourth parameter carried by each reply acknowledgement message in the plurality of reply acknowledgement messages; and the second entity of the network equipment determines the reply message corresponding to each reply confirmation message based on the reference identifier of each reply confirmation message and the reference identifier of each reply message.

Each reply confirmation message and the corresponding reply message jointly form a transaction in the SIP. The reference identifier may be denoted as Transaction ID.

The number of the third parameters carried by each reply message may be one or more, and it should be understood that the third parameters carried by different reply messages are the same, but the values of the third parameters carried by different reply messages are different. And the fourth parameter carried by each reply confirmation message is the same as the third parameter carried by the corresponding reply message, and the value of the fourth parameter is the same as that of the third parameter. Here, specific parameter names of the fourth parameter and the third parameter are the same as those of the first parameter, and therefore, a description thereof will not be repeated.

The second entity of the terminal device determines, based on the third parameter carried in each reply message, the fourth parameter carried in the reply acknowledgement message of each reply message, and the specific processing is similar to that in the foregoing embodiment, where the second entity of the network device determines, based on the first parameter carried in each message, that the second parameter carried in the acknowledgement message of each message is similar, and therefore, the detailed description is omitted.

The manner of determining the reference identifier of each reply message by the second entity of the network device based on the third parameter carried in each reply message in the multiple reply messages is similar to the manner of determining the reference identifier of each message by the second entity of the terminal device based on the first parameter carried in each message in the multiple messages, and is not described in detail. The second entity of the network device determines, based on the fourth parameter carried in each of the multiple reply acknowledgement messages, a processing manner of the reference identifier of each reply acknowledgement message, which is similar to the manner, in the foregoing embodiment, in which the second entity of the terminal device determines, based on the second parameter carried in each of the multiple acknowledgement messages, the reference identifier of each acknowledgement message, and is not described in detail.

The determining, by the second entity of the network device, the reply message corresponding to each reply acknowledgement message based on the reference identifier of each reply acknowledgement message and the reference identifier of each reply message may refer to: and the second entity of the network equipment compares the reference identifier of each reply confirmation message with the reference identifier of each reply message, matches the reply messages with the same reference identifiers with the reply confirmation messages, and obtains the reply messages corresponding to each reply confirmation message.

When the second entity of the terminal device sends the reply acknowledgement message, the order of the reply messages is not necessarily the same. For example, the first reply acknowledgement message of the reply message generated by the second entity of the terminal device may be a reply acknowledgement message corresponding to the second reply message of the plurality of reply messages. However, no matter whether the order of the reply acknowledgement message generated by the second entity of the terminal device is correct, since a pair of the message and the acknowledgement message need to carry the same reference identifier, the reference identifier can be calculated by the parameter carried by the reply acknowledgement message, and the corresponding reply message is determined according to the reference identifier. For example, when the second entity of the network device sends the reply message1, the Transaction ID equal to 3 may be calculated from the third parameter carried in the reply message1, and when the reply message2 is sent, the Transaction ID equal to 4 may be calculated from the third parameter carried in the reply message2. If the second entity of the terminal device first sends the reply acknowledgement message of the reply message2, the fourth parameter and its value carried in the reply acknowledgement message are the same as the third parameter and its value that are the same as the reply message2. Correspondingly, under the condition that the second entity of the network equipment receives the first reply confirmation message, the fourth parameter carried by the second entity of the network equipment is obtained from the first reply confirmation message, and the reference identifier is calculated to be 4; it can be determined that the reply acknowledgement message is the reply acknowledgement message corresponding to the reply message2 based on the Transaction ID being equal to 4. In addition, in this example, for ease of understanding, the Transaction ID (i.e., reference identifier) is represented as equal to 1, 2, 3, 4, etc., but does not represent a limitation on the value of the Transaction ID.

In addition, in the plurality of information segments and the plurality of response information, a type indication may be carried in addition to the correspondence value. The specific description of the correspondence value and the type indication is the same as the foregoing embodiment, and therefore, the description thereof will not be repeated.

In summary, by adopting the above embodiment, the first entity of the terminal device can concurrently transmit a plurality of information segments, so that the information transmission efficiency can be ensured. Further, the second entity of the terminal device can concurrently carry the message of each information segment, thereby further promoting the transmission of the message of the long short message by the terminal device. Moreover, the terminal equipment can determine the information segments corresponding to the response information through the corresponding relation values, so that the problem of disorder of the response information possibly generated by concurrence of the information segments is solved; and the terminal equipment and the network equipment can also determine each message and the corresponding confirmation message based on the reference identifier, thereby solving the problem of possible IMS message disorder in the scene of concurrence of the messages carrying the information segments. Specifically, the SIP protocol is a Transaction protocol, and the MESSAGE and the 200OK (or 202 Accepted) are request response MESSAGE pairs in a non-INVITE Transaction, so that when multiple long short MESSAGE segments are transmitted by the MESSAGE in a concurrency mode, even if disorder occurs in MESSAGE transmission at the IMS layer, the IMS entity can still match the IMS request response MESSAGE pairs according to the Transaction ID calculated and obtained by the relevant header field in the response MESSAGE 200OK (or 202 Accepted), thereby solving the problem of disorder occurring in the transmission process of the IMS MESSAGE in the concurrency mode.

With reference to fig. 9, the foregoing embodiment is exemplarily described by taking a terminal device as a UE, a network device as an IP-SM-GW, a first entity as an SM-RL entity (denoted as SM-RL in fig. 9), a second entity as an IMS entity (denoted as IMS in fig. 9), an information segment as a short message segment RP-DATA, response information as an RP-ACK, a type indication as an MTI, a correspondence value as an MR, and a reference identifier as a Transaction ID as an example:

in step 901, the SM-RL entity at the UE side sends the first short message segment RP-DATA1 (MTI: 0, MR.

And step 902, the SM-RL entity on the UE side sends a second short message segment RP-DATA2 (MTI: 0, MR.

The foregoing steps 901 and 902 may be executed sequentially or concurrently, and are all within the protection scope of the present embodiment. In addition, the process of the SM-RL entity sending the SMs message fragment in step 901 and step 902 may be referred to as SMs-SUBMIT. The description of the aforementioned MTI and MR is the same as the aforementioned embodiment and will not be repeated.

In step 903, the IMS entity on the ue side sends RP-DATA1 (MTI: 0, mr.

Step 904, the ue side IMS entity sends RP-DATA2 (MTI: 0, mr.

Here, MESSAGE1 and MESSAGE2 may be MESSAGEs in the foregoing embodiments; namely, the UE-side IMS entity sends the two sms segments carried in MESSAGE1 (i.e. MESSAGE 1) and MESSAGE2 (i.e. MESSAGE 2) to the network-side IMS entity.

Note that, in this example, the values of the Transaction ID are shown in step 903 and step 904 of fig. 9 only for convenience of understanding, and the aforementioned Transaction ID is 1 and the Transaction ID is 2, which do not mean that the Transaction IDs are carried in

MESSAGEs

1 and 2. But the first parameter carried by the MESSAGE1 and the value thereof can be calculated to obtain the Transaction ID equal to 1, and similarly, the first parameter carried by the MESSAGE2 and the value thereof can be calculated to obtain the Transaction ID equal to 2. In addition, the first parameter may include at least one of: a branch parameter and cseq (command sequence number) in the Via header field, and the description of each parameter regarding the first parameter has been described in detail in the foregoing embodiments, and will not be described repeatedly.

The steps 903 and 904 may be executed sequentially or concurrently, and are all within the protection scope of the present embodiment.

Step 905, after receiving MESSAGE1, the network side IMS entity submits the first short MESSAGE segment RP-DATA1 (MTI: 0, mr.

Step 906, after receiving the MESSAGE2, the IMS entity on the network side submits RP-DATA2 (MTI: 0, mr.

Step 907, the network side IMS entity replies 202 accepted, and the transaction ID is 2, notifying the UE side IMS entity to receive the MESSAGE2 in step 904. Wherein 202 Accepted is the acknowledgement MESSAGE of MESSAGE2 (i.e. MESSAGE 2).

Step 908, the network side IMS entity replies 202 accepted, and the transaction ID is 1, notifying the UE side IMS entity to receive the MESSAGE1 in step 903. Wherein 202 Accepted is the acknowledgement MESSAGE of MESSAGE1 (i.e. MESSAGE 1).

Note that, in this example, the values of the Transaction ID are shown in step 907 and step 908 in fig. 9 only for convenience of understanding, and the aforementioned Transaction ID is 1 and the Transaction ID is 2, and it is not indicated that the "202 Accepted" carries the Transaction ID. But the IMS entity of the network device sends the second parameter and its value carried when the "202 Accepted" is sent, so that the IMS entity of the UE can calculate that the Transaction ID is equal to 1 or 2. Further, the terminal device may determine the MESSAGE corresponding to each "202 Accepted" according to the calculated Transaction ID. Additionally, the second parameter may include at least one of: the branch parameter and cseq (command sequence number) in the Via header field are described in detail in the foregoing embodiments, and a repeated description is omitted here.

Although the IMS layer 202 Accepted replies in step 907 and step 908 are out of order, due to the Transaction mechanism in the IMS message, the same Transaction ID can be calculated for a pair of messages and their acknowledgment messages, so the UE can identify the message corresponding to each acknowledgment message in the IMS layer, thereby solving the problem caused by message out of order.

In step 909, the network side SM-RL entity replies RP-ACK1 (MTI: 3, mr.

In step 910, the network side SM-RL entity replies RP-ACK2 (MTI: 3, mr.

Step 911, the network side IMS entity transmits RP-ACK1 (MTI is 3, MR is 0) to the UE side IMS entity through MESSAGE3, and the Transaction ID is 3. MESSAGE3 is the reply MESSAGE in the previous embodiment. Namely, the network side IMS entity carries RP-ACK1 in MESSAGE3.

In step 912, the network side IMS entity transmits RP-ACK2 (MTI is 3, mr is 1) to the UE side IMS entity through MESSAGE4, and Transaction ID is 4. MESSAGE4 is the reply MESSAGE in the previous embodiment. Namely, the network side IMS entity carries RP-ACK2 in MESSAGE4.

In this example, the values of the Transaction ID are shown in step 911 and step 912 of fig. 9 only for convenience of understanding, and the aforementioned Transaction ID is 3 and the Transaction ID is 4, which do not mean that the Transaction IDs are carried in MESSAGEs 3 and 4. But it means that the Transaction ID is equal to 3 through calculation of the third parameter and the value carried by MESSAGE3, and similarly, the Transaction ID is equal to 4 through calculation of the third parameter and the value carried by MESSAGE4. In addition, the description of the third parameter has been detailed in the foregoing embodiments, and is not repeated here.

In step 913, the SM-RL entity on the ue side receives the response information of RP-ACK1 (MTI is 3, mr is 0) on the network side, and the current RP-ACK is for the first short message segment RP-DATA1 (MTI is 0, mr is 0) in step 901.

In step 914, the SM-RL entity on the UE side receives the response information of RP-ACK2 (MTI is 3, MR is 1) on the network side, and the current RP-ACK is directed to the second short message segment RP-DATA2 (MTI is 0, MR is 1) in step 902.

Step 915, the IMS entity at the UE side replies 200OK and the transaction ID is 4; and informing the network side IMS entity of receiving MESSAGE4 in step 912. Here, "200OK" is the reply confirmation message in the foregoing embodiment.

Step 916, the UE side IMS entity replies 200OK, the transaction ID is 3; and informing the network side IMS entity of receiving the MESSAGE3 in the step 911.

In this example, the values of the Transaction IDs are shown in step 915 and step 916 of fig. 9 only for convenience of understanding, and the aforementioned Transaction ID is 3 and the Transaction ID is 4, and does not mean that the Transaction ID is carried in "200 OK". But the fourth parameter and the value thereof carried by the IMS entity of the UE when sending the "200OK" are represented, so that the IMS entity of the network can calculate the Transaction ID to be equal to 3 or 4. And the IMS entity of the network can determine the MESSAGE corresponding to each '200 OK' according to the computed Transaction ID. The description of each parameter related to the fourth parameter has been detailed in the foregoing embodiments, and will not be repeated here. In addition, for convenience of understanding, the Transaction ID (i.e., reference identifier) is represented as equal to 1, 2, 3, 4, etc., in this example, but does not represent a limitation on the value of the Transaction ID.
