[0042] The technical solutions in the embodiments of the present disclosure will be apparently and completely described with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative in nature and by no means as any limitation on the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.
[0043] Unless specifically stated, the relative arrangement of the components and steps, numerical expressions, and numerical values set forth in the embodiments are not meant to limit the scope of the present disclosure.
[0044] It should be understood that the size of the various portions shown in the drawings is not necessarily drawn to scale in order to make the drawings easier to understand.
[0045] The techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered as part of the specification where appropriate.
[0046] In all the examples shown and discussed herein, any specific value should be interpreted as merely an example, and not as a limitation. Thus, other examples of the example embodiments can have different values.
[0047] It should be noted that similar reference numbers and letters refer to similar items in the following drawings, and thus, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.
[0048] When the mobile network adopts the store-and-forward communication mode, which is a non-real-time communication, the data sent by the UE needs to wait for a period of time to reach the network and be sent out from the network, which causes management problems, such as the ground network being unable to determine the time and location of the UE sending data. Moreover, this problem exists not only in the satellite communication scenario, but also in other communication scenarios using the store-and-forward mode. Therefore, in the related art, the processing accuracy of terminal data can be affected.
[0049] To solve the above technical problems, the present disclosure provides a communication method, a communication system, and related devices.
[0050] Figure 1 A flowchart of a communication method according to some embodiments of the present disclosure is shown. As shown in FIG. 1, the communication method includes the following steps.Figure 1 As shown, the communication method of this embodiment includes step S102.
[0051] In step S102, the first network element sends the uplink data of the user equipment and the first information to the second network element, wherein the first information includes at least one of the time and the location when the user equipment sends the uplink data.
[0052] The first network element can also be referred to as a first network entity. In the scenario of satellite communication, the first network element can be a network element on a satellite. For example, the first network element can be a base station, an MME, an AMF or a UPF on a satellite, etc. The first network element can also be a ground network element. For example, the first network element can be an MME, an SGW, an AMF or a UPF on the ground, etc.
[0053] The second network element can also be referred to as a second network entity. In the scenario of satellite communication, the second network element can be deployed on a satellite or on the ground.
[0054] In the scenario of non-satellite communication, the first network element and the second network element can also be other network-side network elements.
[0055] The user equipment (UE) can also be referred to as a user terminal, a terminal, etc. The UE is a device with wireless transceiving function, which can communicate with one or more core networks (CN) through an access network device in the (R)AN. It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on water, such as on a ship, etc.; it can also be deployed in the air, such as on an airplane, balloon or satellite, etc. The user equipment can be a mobile phone, a tablet computer, a computer with wireless transceiving function, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.
[0056] The UE sends uplink data to a network element of the network side. In some embodiments, the UE sends the uplink data to a network element on a satellite. The network element on the satellite can be the first network element or another network element, such as the third network element. The network element on the satellite can be a base station or a core network element. The satellite is, for example, a non-geosynchronous satellite.
[0057] The uplink data and the first information can be carried using GTP-U. That is, the first network element sends GTP-U data to the second network element, and the GTP-U data includes the uplink data and the first information. In some embodiments, the first information is located in an extension header of the GTP-U data. The uplink data and the first information can be transmitted using piggybacking. Other information, such as the second information, can also be carried in the GTP-U as needed.
[0058] The first network element can directly or indirectly receive the uplink data of the UE. For example, in the case where the UE directly sends the uplink data to the first network element, the first network element can record at least one of the time and the location at which the UE sends the uplink data, or actively receive from the UE at least one of the time and the location at which the UE sends the uplink data. In the case where the UE directly sends the uplink data to a network element other than the first network element and the second network element, such as the third network element, the third network element can send the uplink data and at least one of the time and the location at which the UE sends the uplink data to the first network element.
[0059] Regardless of whether the uplink data and the first information are sent by the UE to the first network element or by the third network element to the first network element, the first network element can temporarily store the uplink data and the first information. That is, the first network element stores the uplink data and the first information. In the case where the first network element receives the uplink data, there can be a case where the first network element cannot connect to the second network element, and therefore, in some embodiments, the first network element can store the uplink data and the first information in the case where the first network element cannot connect to the second network element. In the case where the first network element can connect to the second network element, the first network element directly forwards the uplink data and the first information to the second network element.
[0060] If the first network element cannot send data to the second network element due to the inability to connect to the second network element, the first network element can store the uplink data and the first information and wait for a connection to the second network element. In response to the first network element connecting to the second network element, the first network element sends the uplink data and the first information of the user equipment to the second network element. Thus, the forwarding of data can continue in the case where the first network element and the second network element can connect.
[0061] In some embodiments, the first network element stores the first information and the uplink data sent by the user equipment to the first network element. That is, the uplink data is directly sent by the UE to the first network element. Figure 2A flowchart of a communication method according to some embodiments of the present disclosure is shown. As Figure 2 The communication method of this embodiment includes steps S202-S206.
[0062] In step S202, the UE sends uplink data to a first network element.
[0063] In step S204, the first network element stores the first information and the uplink data.
[0064] The first information can be generated by the first network element or come from the UE.
[0065] For example, in response to the first network element receiving the uplink data from the user equipment, the first network element determines at least one of the time and the location when the user equipment sends the uplink data to obtain the first information.
[0066] For another example, the first information is sent by the UE to the first network element, i.e., step S202 can be specifically that the UE sends the uplink data and the first information to the first network element. When sending the uplink data, the UE can send at least one of the current time and location together with the uplink data to the first network element, or send the uplink data first and then send at least one of the time and location.
[0067] In step S206, the first network element sends the uplink data and the first information of the user equipment to a second network element.
[0068] Through this embodiment, the network element that directly receives the uplink data of the UE can carry the first information when transmitting the uplink data, so that other network elements on the transmission link can accurately process the uplink data based on the first information.
[0069] In some embodiments, the first network element stores the uplink data and the first information sent by other network elements to the first network element. The other network elements are, for example, the third network element mentioned above. The other network elements can be network elements on a satellite or ground network elements. Figure 3 A flowchart of a communication method according to some embodiments of the present disclosure is shown. As Figure 3 The communication method of this embodiment includes steps S302-S308.
[0070] In step S302, the UE sends uplink data to a third network element. The third network element is a network element on a satellite.
[0071] In step S304, the third network element sends the uplink data and the first information to a first network element. The first network element can be a satellite network element or a ground network element.
[0072] In step S306, the first network element stores the first information and the uplink data.
[0073] In step S308, the first network element sends the user equipment's uplink data and first information to the second network element.
[0074] For example, if the first network element is a satellite network element and the second network element is a terrestrial network element, the first network element executes step S308 in response to the first network element being able to connect with the second network element.
[0075] Through this embodiment, the network element that indirectly receives the uplink data of the UE can carry first information when transmitting the uplink data, so that other network elements after the network element on the transmission link can accurately process the uplink data based on the first information.
[0076] The two methods described above can also be combined. That is, after the UE sends uplink data, multiple network elements on the uplink data transmission link can act as "first network elements," carrying at least one of the time and location information of the UE when sending the uplink data. For example, the UE sends uplink data to network element A, and network element A stores at least one of the time and location information of the UE when sending the uplink data as first information; then, network element A sends the uplink data and the first information to network element B; network element B can then send the uplink data and the first information to network element C. Thus, the first information is always carried during the transmission of the UE's uplink data, enabling the network element processing the uplink data to perform more accurate processing based on the first information.
[0077] After receiving the uplink data and the first information, the second network element can process the uplink data based on the first information. Alternatively, it can continue to send uplink data to other network elements, carrying the first information with it. Uplink data processing may include handling regulatory requirements for communication data, such as processing requirements based on Lawful Interception (LI).
[0078] Through the above embodiments, information such as the time and location of the UE when sending uplink data can be carried during the uplink data transmission process from the UE. As a result, the network element receiving the information can perform more accurate processing based on the time and location information of the UE when sending uplink data.
[0079] When processing uplink data, information such as time and location may or may not be needed. The first network element can determine whether to carry this first information when sending uplink data based on configuration or instructions from other network elements.
[0080] In some embodiments, the first network element determines, based on configuration, whether to carry first information when sending uplink data. This configuration information may include an indication of whether to carry the first information, for example, by specifying a field and its value to indicate that the first information needs to be carried when sending uplink data. Furthermore, the configuration information may also include conditions for carrying the first information. For example, the first information may be carried when sending all transmitted uplink data; or, the first information may be carried only for specified uplink data, which may be uplink data from a specified user equipment, uplink data of a specified type, uplink data within a specified time period, uplink data within a specified service process, etc.
[0081] In some embodiments, the first network element receives an instruction sent by the second network element, which is used to determine whether to carry first information when sending uplink data. This instruction may be generated autonomously by the second network element and sent to the first network element, or it may be sent to the second network element by other network elements. That is, the requesting end of the first information notifies the sending end to carry the first information when sending uplink data.
[0082] Therefore, when the first network element needs to send first information, the second network element can send an instruction to the first network element. For example, during the establishment or modification process of a user plane session of a user equipment, the second network element can receive the instruction sent by the second network element. Thus, based on at least one of the time and location when the UE sends uplink data, the uplink data can be processed more accurately during the establishment or modification process of the user plane session.
[0083] The following is for reference. Figure 4A and 4B A signaling flowchart describing the communication method of this disclosure.
[0084] Figure 4A A signaling flowchart of a communication method according to some embodiments of this disclosure is shown. Figure 4A As shown, the communication method of this embodiment includes steps S402 to S414.
[0085] In step S402, the UE or the network initiates a user plane session establishment or modification procedure to establish or modify the UE's user plane resources in preparation for subsequent data transmission by the UE through the user plane.
[0086] After the UE initiates a user plane session establishment or modification procedure, satellite network element A can send a request to ground network element B, and ground network element B can send a request to ground network element C. Then, ground network element C sends a response to ground network element B, and ground network element B sends a response to satellite network element A. These two responses may, for example, carry an indication, which can be used by satellite network element A to determine whether to include first information when sending uplink data.
[0087] In step S404, StarNet element A determines that when sending uplink data of UE, it needs to carry first information, namely at least one of the time and location of UE when sending uplink data.
[0088] For example, if the UE's user plane session requires information such as the time and location of uplink data transmission, the relevant network element (e.g., a ground network element) will, during the session establishment or modification process, notify the sending end from the requesting end, instructing that the first information be carried in subsequent UE uplink data transmissions. Figure 4B For example, step S404 above can be specifically implemented as S4042 to S4048. In step S4042, satellite network element A sends a request to ground network element B to establish or modify a user plane session; in step S4044, ground network element B sends a request to ground network element C to establish or modify a user plane session; in step S4046, ground network element C sends a response to ground network element B to establish or modify a user plane session, the message including an indication carrying first information; in step S4048, ground network element B sends a response to satellite network element A to establish or modify a user plane session, the message including an indication carrying first information.
[0089] In a 4G network, the PGW can send instructions to the SGW, the SGW can send instructions to the MME, and the MME can send instructions to the eNB to notify the sender from the demand side. The satellite network element A can be either an eNB or an MME.
[0090] In a 5G network, the SMF can send instructions to the AMF, and the AMF can send instructions to the gNB, thus notifying the sender from the demand side. The satellite network element A can be the gNB, AMF, or UPF.
[0091] In step S406, the UE sends uplink data to the satellite network element A at one or more time points. Figure 4A and 4B The example of step S406 represents one or more transmission processes of the UE.
[0092] In step S408, when uplink data sent by the UE is received, StarNet element A receives and stores the uplink data sent by the UE, and also stores the time and location information of the UE sending the uplink data, i.e., the first information.
[0093] In step S410, when the satellite network element A can connect to the ground (i.e., the ground network element), the satellite network element A sends the uplink data sent by the UE and the first information stored in it to the ground network element B.
[0094] In 4G networks, terrestrial network elements can be MME or SGW.
[0095] In 5G networks, terrestrial elements can be AMF or (i)UPF.
[0096] In some embodiments, the first information may be included in the GTP-U corresponding to the uplink data. For example, the piggyback method can be used.
[0097] In step S412, ground network element B sends the UE's uplink data and the first information to other ground network elements C. This first information can be included in the GTP-U corresponding to the uplink data. For example, a piggyback method can be used.
[0098] In 4G networks, the terrestrial network element C can be a PGW.
[0099] In 5G networks, the terrestrial network element C can be a UPF.
[0100] In step S414, the ground network element C performs corresponding processing based on the uplink data sent by the UE and the first information.
[0101] For example, based on information such as the time and location when the UE sends uplink data, processing that complies with regulatory requirements for communication can be performed, such as LI-based processing.
[0102] Through the above embodiments, when the satellite network element cannot connect to the ground, it can temporarily store the uplink data sent by the UE and the corresponding first information, such as the time and location when the uplink data was sent. When the satellite network element can connect to the ground, it sends the uplink data and the first information to the ground network element. Furthermore, the ground network element, upon receiving the uplink data and the first information, also carries the first information when continuing to transmit uplink data. Therefore, the uplink data sent by the UE can be accurately processed based on the time and location information when the UE sent the uplink data.
