The present disclosure relates generally to wireless communication, including short message service (SMS) and, in particular, to the reduction of communications traffic between mobile terminals and the base station in the course of applying SMS service.
Wireless frequency spectrum is an important resource for wireless communication services. With the development of broadband wireless communication, the demand for frequency spectrum tends to be in rapid and exponential growth. One of the embodiments is the popularity of small piece data services such as SMS and microblog. SMS is a tool that provides the user of mobile phone with short messages or other information. Microblog is a new means of communication. Microblog users may publish instant messages by distributing short posts over the network via mobile terminals such as mobile phones.
The data transportation capacity provided by the current wireless access network for data service is limited by wireless frequency spectrum resources. In reality, it often happens that transportation of a great deal of SMS messages of small piece data would burst in a short period of time. For example, at large gatherings, the huge communications traffic due to a great deal of SMS messages sent by group messaging would have a serious impact on a wireless access network, often leading to temporary unavailability of the SMS service.
In one embodiment, a method for group messaging at a mobile terminal in an autonomous network includes acquiring a message and a list of target identifiers, the list of target identifiers containing the identifiers of multiple mobile terminals to which the message is to be sent; transmitting the message via the autonomous network to any mobile terminal of the multiple mobile terminals that is located in the autonomous network, and removing the identifier of the mobile terminal from the list of target identifiers to obtain an updated list of target identifiers; generating an aggregate message, wherein the aggregate message contains the message and the identifiers in the updated list of target identifiers; sending the aggregate message to a base station if the length of the aggregate message does not exceed a pre-defined threshold; and dividing the aggregate message into multiple fragment messages and then sending the multiple fragment messages to the base station if the length of the aggregate message exceeds the pre-defined threshold.
In another embodiment, a proxy apparatus for group messaging at a mobile terminal in the autonomous network includes an acquiring device, configured to acquire a message and the identifiers of multiple mobile terminals to which the message is to be sent; a transmitting device, configured to transmit a message via the autonomous network to one or more mobile terminals in the autonomous network; and a message aggregating device, configured to generate an aggregate message, the aggregate message containing a message and identifiers of multiple mobile terminals to which the message is to be sent, wherein the transmitting device is further configured to send the aggregate message generated by the message aggregating device to a base station of mobile terminals.
In still another embodiment, a method for message processing in a base station of wireless communication network includes receiving a message frame from a mobile terminal; if the payload of the received message frame is a fragment message, assembling the fragment message and other fragment messages belonging to the same series as the fragment message into an aggregate message; disassembling the aggregate message in the payload of the received message frame or obtained by assembling the fragment message to generate multiple standard downlink frames each containing a message and a target mobile terminal identifier, and sending the message to the mobile terminal corresponding to each target mobile terminal identifier.
The features, advantages and other aspects of the various embodiments of the disclosure will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereon, by way of illustration, but non-limiting examples, the embodiments of the disclosure are illustrated. In the accompanying drawings:

Hereinafter, the principle and spirit of the present disclosure will be described with reference to various exemplary embodiments. It should be understood that provision of these embodiments is only to enable those skilled in the art to better understand and further implement the present disclosure, not intended for limiting the scope of the present disclosure in any manner.
In the following, various embodiments of the disclosure are described in detail with reference to accompanying drawings. For purpose of easy description and content consistency, in the following detailed description, the SMS will be taken as an example of short piece data service and the mobile phone will be taken as an example of smart mobile terminal/device. However, the disclosure is obviously not limited to that. Therefore, due to the need of the context in the specification, the term “mobile terminal” is sometimes used to represent “mobile phone”, and vice versa.
The mobile terminals 111-118 and the base station BS are a part of the wireless communication network 100. The mobile terminals and the base station communicate with an assigned wireless frequency band. When the mobile terminals transmit messages to each other via the base station, a source mobile terminal that originates a message would send an up-link frame (UL-frame) comprising a part of frame header and a part of frame content via the up link to the base station BS. The base station BS sends a down-link frame (DL-frame) via the down link to a target mobile terminal that received the message. Specific details such as coding, sending, receiving, decoding of the UL-frame and the DL-frame, are known in the art and thus a detailed description of the same is omitted here.
It is noted that although only eight mobile terminals are shown in
The autonomous network 101 is a social relation based autonomous network (SAN). In such an autonomous network, mobile terminal users have some social relationships with each other, such as friends, colleagues, relations, club members and so on. Users may register with, for example, a social relationship server (SRS) providing social relationship registration service and establish various social relationships among themselves. The social relationship server SRS may also establish and save such social relationships automatically with such information as the communications record of the users, and provide query. In SAN, the short message route in the network layer is determined according to social relationships. WLAN or Bluetooth is taken as the Media Access Control Layer protocol for performing the transmission instruction issued by the Network Layer, so that end-to-end multi-hop transmission of SMS data may be realized. The mobile terminals in the autonomous network 101 may communicate with each other wirelessly via a connection channel provided by the autonomous network. For example, mobile terminals 111-115 may realize short message communication with each other by the “Bluetooth” function.
As shown in
A SAN network list may be used to store identification information of the mobile terminals in the SAN, such as a mobile phone number. For example, assuming the phone numbers of the mobile terminals 111, 112, 113, 114 and 115 in the SAN of
Furthermore, the SAN network list may take the form of an adjacency list for representing connection relationships among mobile terminals, as the following:
A1:A2, A4
A2:A4
A3:A4
A4:A1, A2, A3, A4, A5
A5, A4
Wherein, for example, “A1:A2, A4” denotes that the mobile terminal 111 is adjacent to the mobile terminal 112 and 114 respectively, “A4:A1, A2, A3, A4, A5” denotes that the mobile terminal 114 is adjacent to the mobile terminal 111, 112, 113, 114 and 115 respectively.
Generally speaking, the mobile terminals in the autonomous network SAN 101 have different capabilities. The mobile terminals with relatively strong capability generally have following one or more capabilities, including: a relatively strong electric power endurance capability, such as having relatively adequate battery charge or having access to active power supply; a relatively strong processing capability, such as large storage, rapid in computing speed; having well established wireless connection with surrounding mobile terminals, and capable of realizing relatively stable wireless data transmission with surrounding mobile terminals; and a capability of establishing stable connection with wireless network external to the SAN.
As shown in
In practical implementations, other or more capability evaluation items may be set and a capability evaluation function Q may be used to quantify the capability of the mobile terminal.
The mobile terminal with stronger capability may become the relay device when other mobile terminals in the autonomous network are transmitting messages. There might be multiple mobile terminals qualified for acting as relay devices, one of which being the master relay device. The communication connections among the multiple relay devices have hierarchical relations like the tree structure, for example.
In the following, a method of the disclosure for group messaging at a mobile terminal in the autonomous network will be described by way of example.
As shown in the figure, in block 210, the mobile terminal 114 acquires a message MSG and the identifiers of multiple target mobile terminals to which the message is to be sent. In other words, the mobile terminal 114 acquires a message MSG and a list of target identifiers that contains the identifiers of multiple mobile terminals to which the message is to be sent.
According to one embodiment of the disclosure, the mobile terminal 114 acquires the message and the identifiers of multiple target mobile terminals based on a user's input. To facilitate description, the identifiers of target mobile terminals are also referred to as “target identifiers” below. Assuming the above list of target identifiers is <A3, A5, A6, A7, A8>, the target identifiers contained in the list are respectively the identifiers of the mobile terminal 113, 115, 116, 117 and 118. For example, “A3” denotes the mobile terminal 113. If the mobile terminal 113 is a mobile phone, then “A3” could be a phone number.
In block 220, the message is transmitted via the autonomous network to any mobile terminal of the multiple mobile terminals that is located in the autonomous network, and the identifier of the mobile terminal is removed from the list of target identifiers to obtain an updated list of target identifiers. In other words, for one or more mobile terminals corresponding to target identifiers that are located in the autonomous network 101, the message is transmitted via the autonomous network 101 to the one or more mobile terminals and the identifiers of the one or more mobile terminals are removed from the list of target identifiers.
For example, the mobile terminal 113 corresponding to “A3” is located in the autonomous network 101, so the mobile terminal 114 transmits the message MSG to the mobile terminal 113 via the autonomous network 101, and removes A3 from the list of target identifiers. Similarly, the mobile terminal 115 corresponding to “A5” is located in the autonomous network 101, so the mobile terminal 114 transmits the message MSG to the mobile terminal 115 via the autonomous network 101, and removes “A5” from the list of target identifiers. The message transmission from mobile terminal 114 to the mobile terminals 113 and 115 may be implemented by Bluetooth technology, for example.
According to one embodiment of the disclosure, block 220 may first detect whether mobile terminals corresponding to the acquired multiple target identifiers are located in the autonomous network 101.
According to one embodiment of the disclosure, the mobile terminal 114 may detect whether a mobile terminal is located in the autonomous network according to the SAN network list as described above.
If a certain mobile terminal is located in the autonomous network, then the message is transmitted to the mobile terminal via the autonomous network 101.
As a result of block 220, the content of target identifier list is updated to be <A6, A7, A8>.
In block 230, an aggregate message is generated, wherein the aggregate message contains the message and the updated list of target identifiers. In the present example, the aggregate message generated contains the message MSG and the target identifiers A6, A7 and A8.
According to an embodiment of the disclosure, the aggregate message also contains information indicating the position of the message MSG and the updated target identifier list <A6, A7 and A8> in the aggregate message.
With reference to
As shown in the figure, the aggregate header 310 is 4 (four) characters in length, which comprises:
Bit 0: message indicator 311, indicating aggregate message if the value of the bit is 1, indicating fragment message if the value is 0;
Bits 1-6: message type 312, indicating a non-standard SMS frame if the value is “111111”;
Bits 7-18: length of aggregate body 313, the value of which indicates the length of aggregate body 320 of aggregate message 300, the unit of the length being character; and
Bits 19-29: identifier position 314, the value of which indicates the starting position of the target identifier list 322 in the aggregate message 300.
The message content 321 includes the content to be sent by group messaging, for example MSG.
The identifier list 322 comprises all the target identifiers in the target identifier list. Each target identifier in the identifier list 322 occupies a fixed length, or, target identifiers are separated by a specific separator between them.
With such a format, the starting position of the target identifier list 322 in the aggregate message may be determined according to the content of the identifier position 314. Then the position of each of target identifiers may be further determined according to the fixed length or the separator for the target identifier. The position of the message MSG can be determined according to the length of the aggregate header 310 and the target identifier position 314.
Those skilled in the art shall appreciate that, in practice, the length and content of the aggregate header 310 may be set according to requirements. Not only may the content and position of the message indicator 311, the message type 312, the payload length 313 and the identifier position 314 be adjusted, additional information may also be included into the aggregate header.
According to one embodiment of the disclosure, the aggregate header 310 may further contain the identifier of the source mobile terminal originating the group messaging of the message. Thus, the base station BS may determine that the message MSG is initially originated from the source mobile terminal represented by the identifier.
Referring again to
If the length of the aggregate message 300 does not exceed the pre-defined threshold, the aggregate message 300 is sent to a base station BS in block 250. Then, the process ends.
After the base station BS receives the UL-frame whose payload is the aggregate message 300, it will perform corresponding parsing. This further described below in conjunction with
From the foregoing, it will be seen that if the length of the aggregate message does not exceed the pre-defined threshold, the aggregate message only needs to be transmitted from the mobile terminal 114 to the base station BS once, instead of three times, in order to sent the message to three target mobile terminals 116, 117 and 118. Thus the occupation of air interface bandwidth between the terminal and the base station could be reduced.
If the length of the aggregate message exceeds the pre-defined threshold, then the process proceeds to block 260, where the aggregate message is divided into multiple fragment messages.
For example, assuming that the pre-defined threshold is 70 characters, then the aggregate message 300 is divided into multiple fragment messages to so that the fragment messages, except the last one, are each 70 characters in length.
With reference to
As shown in the figure, the length of the fragment header 410 is 2 characters, which includes Message indicator 411 (bit 0), indicating fragment message if the value of the bit is 0 (zero), and message type indicator 412 (bits 1-6), used for distinguishing the fragment message of the disclosure from the standard SMS message. For example, a value of “111111” is used to indicate that the current frame is a fragment message.
End-of-fragment indicator 413 (bit 7) is used for indicating whether the fragment message is the last one of a series of fragment messages. For example, the value of End-of-fragment indicator may be set to “1” to indicate the fragment message is the last one.
Message identifier 414 (bits 8-10) is a field used for identifying different aggregate messages. For example, when the mobile terminal 114 sends a first aggregate message to the base station BS, the value of the field is “000” (binary). The value of the field will be increased by degrees along with the increase of the number of aggregate messages sent by the mobile terminal 114 to the base station BS. When the mobile terminal 114 sends the eighth aggregate message to the base station BS, the value of the field is “111”.
Serial number 415(bits 11-15) is a field used for identifying different fragment messages within the same aggregate message. The field is valid inside the same aggregate message. The initial value is “00000” (binary) corresponding to a first fragment message and the value will be increased by degrees as the number of fragment messages is increased, up to a maximum value of “11111”. So the field can identify 32 fragment messages within the same aggregate message.
The fragment body 420 is filled with the data obtained by sequentially splitting the aggregate message 300 including the aggregate header 310.
Following the example shown in
As shown in
The fragment body 420 of the fragment message 402 contains the remaining part of target identifier list (322), i.e., “789; 823456789”. Besides, the value of the End-of-fragment indicator 413 in the fragment header 410 of the fragment message 402 is set to 1, because the fragment message 402 is the last one in the generated series of fragment messages.
Returning to
Next, it is assumed that the user of a certain mobile terminal 111 intends to send a message with the content of MSG by group messaging to mobile terminals 113, 115, 116, 117 and 118. According to one embodiment of the disclosure, the mobile terminal 111 may first select a relay device from multiple mobile terminals in the social relation based autonomous network SAN 101. Generally speaking, the relay device that may be selected by the mobile terminal is a mobile terminal with relatively strong capability in the autonomous network SAN 101.
The below mechanism may be followed in determining a mobile terminal with relatively strong capability in the autonomous network SAN 101 to act as the relay device. When a mobile terminal starts, it will firstly launch broadcast information to search whether or not there is existed a SAN. If there is existed a SAN, the mobile terminal would launch a request for joining in the SAN to the mobile terminals in the SAN. The other mobile terminals in the SAN would learn the joining of the new mobile terminal and update respective adjacency lists. Otherwise, the mobile terminal would set up a SAN by itself, become a number of the SAN and automatically become the master relay device, with the value of capability assessment function Q being q.
The addresses or identifiers of other members in the SAN are acquired, and comparison is made between the value q′ of its own capability assessment function Q to the value q of the capability assessment function Q of the current master relay device. If the difference q′−q is greater than a pre-defined threshold, the current master relay device will be replaced by the mobile terminal.
The mobile terminals in the SAN periodically report their own values of the capability assessment function Q to the master relay device. The master relay device maintains a list of nodes sorted according to values of Q of all mobile terminals within its scope coverage. And the node list is sent to the surrounding mobile terminals as a copy. At anytime, if there is a mobile terminal, the difference of whose value q′ of capability assessment function Q of a mobile terminal and the value q of the capability assessment function Q of the current master relay device is greater than a pre-defined threshold, the mobile phone will replace the current master relay device.
When a mobile terminal normally exits from the SAN, it informs other surrounding mobile terminals to remove it from their route tables and informs the master relay device to remove it from the node list. The master relay device sends maintenance information to other mobile terminals periodically. If no reply is received from a certain mobile terminal upon a time-out, it indicates that the mobile terminal exits abnormally. Then the master relay device will broadcast to all mobile terminals in the SAN informing them to remove the exit mobile terminal from their route tables, and remove it from the node list.
If the master relay device normally exits from the SAN, it selects a mobile terminal with the highest Q value according to the node list, requests it to become the master relay device, and transfers management information to it. All mobile terminals in the SAN are notified of the updating of the master relay device. If the master relay device exits from SAN abnormally, other mobile terminal will not receive maintenance information from the master relay device upon a time-out. The relay device with a copy of the node list will select the mobile terminal with the highest Q value to be the master relay device according to the node list.
Assuming the relay device selected by the mobile terminal 111 is the mobile terminal 114, the mobile terminal 111 will transmit, via the SAN 101, the message MSG and the target identifier list <A3,A5,A6,A7,A8> to the mobile terminal 114 acting as the relay device.
Referring again to
The mobile terminal 114 may proceed with Block 220 to 270 so as to complete the processing of the message MSG and the target identifier list <A3,A5,A6,A7,A8>. The details are not repeatedly described herein.
According to one embodiment of the disclosure, in this case, in block 230 of generating aggregate message, the mobile terminal 114 also sets the identifier of the source mobile terminal 111 originating the group messaging in the aggregate header of the aggregate message.
According to one embodiment of the disclosure, prior to transmitting the message MSG and the target identifier list <A3,A5,A6,A7,A8> to the mobile terminal 114, the mobile terminal 111 may conduct aggregating processing of the message MSG and the target identifier list <A3,A5,A6,A7,A8> to generate an aggregate message. Then the aggregate message is transmitted to the mobile terminal 114. The mobile terminal 111 may conduct message aggregation with respect to the message MSG and the target identifier list <A3,A5,A6,A7,A8> in the same way as generating aggregate message shown in
In this case, what the mobile terminal 114 acquires from the mobile terminal 111 is the aggregate message containing the message MSG and the target identifier list <A3,A5,A6,A7,A8>.
According to one embodiment of the disclosure, the mobile terminal 114 that acquires the aggregate message containing the message MSG and the target identifier list <A3,A5,A6,A7,A8> from the mobile terminal 111 may obtain the message and each target identifier therein by parsing the aggregate message. Specifically, as described above in conjunction with
In the above two embodiments, the source mobile terminal 114, as well as the source mobile terminal 111, sends message to five target mobile terminals by group messaging. But, the mobile terminal 114 only needs to send the message MSG to three mobile terminal 116,117 and 118 via the base station BS.
Furthermore, although the mobile terminal 114 needs to send message to the three mobile terminals via the base station BS, the mobile terminal 114 merely needs to transmit data to the base station BS twice. This shows that, by applying the embodiments of the disclosure, the times of signaling interaction and the up-link communications traffic between the mobile terminal and the base station may be reduced, thereby reducing the occupation of wireless bandwidth of the base station. In general, the more the numbers of identifiers for group messaging, the shorter the message MSG is.
The method for group messaging at a mobile terminal in the autonomous network is described above. Those skilled in the art shall appreciate the above method may be implemented by configuring a proxy at the mobile terminal.
According to the same inventive concept, the disclosure also provides a proxy apparatus for group messaging at a mobile terminal in the autonomous network.
As shown in the figure, according to an embodiment of the disclosure, a proxy apparatus 600 for group messaging MSG at mobile terminal (111 . . . 117) in an autonomous network 101 comprises: an acquiring device 610 which is configured to acquire a message and the identifiers of multiple mobile terminals to which the message is to be sent; a transmitting device 620 which is configured to transmit a message via the autonomous network to one or more mobile terminals in the autonomous network; a message aggregating device 630 which is configured to generate an aggregate message 300, the aggregate message containing the message and the identifiers of multiple mobile terminals to which the message is to be sent, wherein the transmitting device 620 is further configured to send the aggregate message generated by the message aggregating device 630 to a base station BS of mobile terminals.
According to one embodiment of the disclosure, the transmitting device 620 is further configured to transmit the aggregate message 300 generated by message aggregating device 630 to one or more mobile terminals in the autonomous network 101.
According to one embodiment of the disclosure, the proxy apparatus 600 further comprises a message splitting device 640 which is configured to divide one aggregate message 300(301) into multiple fragment messages 400(401, 402), wherein the transmitting device 620 is further configured to send the fragment messages 400(401, 402) generated by the message splitting device 640 to a base station BS of mobile terminals.
According to one embodiment of the disclosure, the proxy apparatus 600 further comprises a disassembling device 650 which is configured to extract the message and each of the identifiers of multiple mobile terminals from the aggregate message containing the message and the identifiers of the multiple mobile terminals to which the message is to be sent.
According to one embodiment of the disclosure, the proxy apparatus 600 further comprises a detecting device which is configured to detect whether the mobile terminals corresponding to the identifier of multiple mobile terminal acquired by the acquiring device 610 are located in the autonomous network.
According to one embodiment of the disclosure, the detecting device 660 may detect whether a mobile terminal is located in the autonomous network according to the SAN network list described above.
The functions of various devices contained in the above proxy apparatus 600 and details of their implementation have been fully elaborated in previous description of various embodiments of the inventive method for group messaging at a mobile terminal in the autonomous network given in conjunction with drawings; thus they will not be repeatedly described here.
Various embodiments of the method and apparatus for group messaging at a mobile terminal in the autonomous network have been described in above. From the above description it can be known that the payload of a UL frame transmitted from the mobile terminal to the base station may comprises an aggregate message or a fragment message. Accordingly, the disclosure also provides a method for processing a message containing the aggregate message and the fragment message at the base station BS.
Generally speaking, the disclosure provides a method for message processing in a base station of wireless communication network, comprising: receiving a message frame from a mobile terminal; if the payload of the received message frame is a fragment message, then assembling the fragment message and other fragment messages belonging to the same series as the fragment message into an aggregate message; disassemble the aggregate message in the payload of the received message frame or obtained by assembling the fragment message to generate multiple standard downlink frames each containing a message and a target mobile terminal identifier, and sending the message to the mobile terminal corresponding to each target mobile terminal identifier.
Referring to
As shown in
If it is determined in decision block 520 that the payload is a standard SMS message, then, in block 530, the SMS message is forwarded in a standard manner. Then the processing of the frame ends. On the other hand, if it is determined in decision block 520 that the payload is not a standard SMS message, then, in decision block 540, it is determined whether the payload is an aggregate message. As described above in conjunction with
If, in decision block 540, it is determined that the payload is an aggregate message is determined, the message frame is divided into one or more standard SMS message frames in block 542. Then the process turns to block 530, where the SMS message is forwarded in a standard manner. Then the processing of the frame ends.
As described above in conjunction with
If, in decision block 540, it is determined that the payload is not an aggregate message, then in decision block 550, it is determined whether the payload is fragment message. As described above, in the case that message indicator bits 311 and 411 are used for distinguishing aggregate message from fragment message, the determination operations in decision blocks 540 and 550 may be merged as one operation.
If, in decision block 550, it is determined that the payload is fragment message, the process turns to decision block 552. In decision block 552, it is determined whether the payload is the last fragment message in a series of fragment messages. As described in the above in conjunction with
If it is determined that the payload is not the last fragment message, the process turns to block 554. In block 554, the received fragment message is stored. Then in block 556, the next fragment message is received. If the payload is the last fragment message is determined, then the process turns to block 560.
In Block 560, the fragment message and other fragment messages belonging to the same series as the fragment messages are assembled into an aggregate message. The other fragment messages belonging to the same series as the fragment message are those that are in block 554. As described above in conjunction with
For example, the method of assembling the fragment message 401 and 402 shown in
After block 560, the process proceeds to blocks 542 and 530. Then the process ends. As a result, the base station BS sends the message MSG to mobile terminals 116, 117 and 118 via downlink.

In other embodiments of the present disclosure, the method may have more, or less, or different blocks, and numbering the blocks is only for making the depiction more concise and much clearer, but not for stringently limiting the sequence between each blocks, and the sequence of blocks may be different from the depiction.
Therefore, in some embodiments, the above one or more optional blocks may be omitted. Specific embodiment of each block may be different from the depiction. All these variations fall within the spirit and scope of the present disclosure.

A network adapter may also be coupled to the system such that the data processing system can be coupled to other data processing systems, remote printers or storage devices via an intermediate private or public network. A modem, a cable modem, and an Ethernet card are merely examples of a currently usable network adapter.
In view of the above-mentioned problems, one embodiment of the disclosure is to reduce communications traffic and the number of signaling interactions between the mobile terminal and the base station for the service of group messaging of small piece data by mobile terminals (such as SMS group messaging) in wireless access network.
By applying various embodiments of the disclosure, on one hand, by using social relation based autonomous network to transmit messages to a part of mobile terminals as target of group messaging, redundant traffic between the mobile terminal and the base station could be eliminated, thereby reduce the required communications traffic through the base station; on the other hand, by optimized treatment of the messages to be transmitted via the base station (such as by message aggregating, fragmenting, assembling and disassembling), the communications traffic transmitted through the base station could also be reduced.
