Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method, apparatus, device, and storage medium for joint networking. Background Art

[0002] Non-terrestrial network (NTN) is one of the current hotspots in mobile communication research. A non-terrestrial network is a wireless communication network carried by aerial platforms such as spacecraft or airborne equipment (e.g., geostationary earth orbit satellites, low earth orbit satellites, highly elliptical orbit satellites, high-altitude platform stations (HAPS)), and is an effective supplement to the existing terrestrial mobile communication network (i.e., the terrestrial network). Currently, when a terminal device accesses the network, a selective access method can be used to jointly network the non-terrestrial network and the terrestrial network. Specifically, if the terminal device can search for the signal of the terrestrial network, it accesses the terrestrial network; if the terminal device cannot search for the signal of the terrestrial network, it attempts to access the non-terrestrial network.

[0003] However, in the above method, when jointly networking the non-terrestrial network and the terrestrial network by the selective access method, the terminal device needs to switch between the non-terrestrial network and the terrestrial network when moving, resulting in unstable network speed of the terminal device, and moreover, there may be a problem of switching failure. Therefore, the user experience when accessing the non-terrestrial network and the terrestrial network is poor. Summary of the Invention

Further, when the remaining network carrying capacities of the first cell and the multiple second cells are greater than or equal to a preset network carrying capacity, control the first cell to carry the first service of the terminal device, and control the multiple second cells to carry the second service of the terminal device; when the remaining network carrying capacities of the first cell and the multiple second cells are less than the preset network carrying capacity, activate the third cells corresponding to at least one deactivated terrestrial base station, control the first cell to carry the first service of the terminal device, and control the multiple second cells and the at least one third cell to carry the second service of the terminal device.

[0019] That is, when the network loads of the non-terrestrial network and the currently activated terrestrial network are relatively low, different services of the terminal device can be carried by the non-terrestrial network and the currently activated terrestrial network; when the network loads of the non-terrestrial network and the currently activated terrestrial network are relatively high, activate the previously deactivated terrestrial network, and carry different services of the terminal device by the non-terrestrial network, the previously activated terrestrial network, and the newly activated terrestrial network.

[0020] Through the above method, different services of the terminal device can be carried by the cells of the aerial base station and the cells of the terrestrial base station, and when the cells of the aerial base station and the cells of the terrestrial base station cannot meet the traffic volume of the terminal device, activate the cells of the new terrestrial base station, so as to carry different services of the terminal device by the cells of the aerial base station, the cells of the terrestrial base station, and the cells of the newly activated terrestrial base station. Thus, the technical problem in the prior art that when joint networking of a non-terrestrial network and a terrestrial network is performed by a selective access method, the terminal device needs to switch between the non-terrestrial network and the terrestrial network, resulting in unstable network speed of the terminal device, is solved, and the user experience is improved.

[0031] Next, the technical solutions in the embodiments of this application will be described in conjunction with the accompanying drawings in the embodiments of this application.

[0032] In the description of this application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. Herein, "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, "at least one" and "multiple" refer to two or more. The words such as "first" and "second" do not limit the quantity and execution order, and the words such as "first" and "second" do not necessarily limit being different.

[0033] After the current non-terrestrial network is completed for networking, there are problems of overlapping coverage and networking coordination with the existing terrestrial network. Currently, for non-terrestrial networks and terrestrial networks, the common networking solution is selective access. Specifically, if the terminal device can search for the signal of the terrestrial network, it accesses the terrestrial network; if the terminal device cannot search for the signal of the terrestrial network, it attempts to access the non-terrestrial network.

[0034] However, in the above method, when jointly networking a non-terrestrial network and a terrestrial network through a selective access method, in current mobile communications, when a terminal device moves, it needs to switch between a cell of the non-terrestrial network and a cell of the terrestrial network to achieve the mobility of the terminal device. Inevitably, traffic drops and data delays will occur during the switching process, resulting in unstable network speed of the terminal device. Moreover, there may be a problem of switching failure, thus affecting the user's service experience.

[0035] In addition, the cells of the non-terrestrial network and the cells of the terrestrial network are always kept on. If the network load of a certain cell is small, it will cause a great waste of resources and increase the operating cost of the operator.

[0036] The present application provides a joint networking method. When it is necessary to jointly network a non-terrestrial network and a terrestrial network for a terminal device, the remaining network carrying capacity of the first cell corresponding to the air base station connected to the terminal device and the remaining network carrying capacity of the second cells corresponding to multiple turned-on ground base stations included in the first cell can be obtained. Further, when the remaining network carrying capacity of the first cell and the multiple second cells is greater than or equal to a preset network carrying capacity, the first service of the terminal device is carried by the first cell, and the second service of the terminal device is carried by the multiple second cells; when the remaining network carrying capacity of the first cell and the multiple second cells is less than the preset network carrying capacity, at least one third cell corresponding to a turned-off ground base station is turned on, the first service of the terminal device is carried by the first cell, and the second service of the terminal device is carried by the multiple second cells and at least one third cell.

[0037] That is, when the network loads of the non-terrestrial network and the currently turned-on terrestrial network are low, different services of the terminal device can be carried by the non-terrestrial network and the currently turned-on terrestrial network; when the network loads of the non-terrestrial network and the currently turned-on terrestrial network are high, the previously turned-off terrestrial network is turned on, and different services of the terminal device are carried by the non-terrestrial network, the previously turned-on terrestrial network and the newly turned-on terrestrial network.

[0038] Through the above method, different services of the terminal device can be carried by the cells of the air base station and the cells of the ground base station, and when the cells of the air base station and the cells of the ground base station cannot meet the traffic volume of the terminal device, the cells of the newly turned-on ground base station are turned on, so as to carry different services of the terminal device by the cells of the air base station, the cells of the ground base station and the cells of the newly turned-on ground base station. Thus, the technical problem that when jointly networking a non-terrestrial network and a terrestrial network through a selective access method in the prior art, the terminal device needs to switch between the non-terrestrial network and the terrestrial network, resulting in unstable network speed of the terminal device, is solved, and the user experience is improved.

[0039] A joint networking method provided by an embodiment of the present application can be applicable to a joint networking system. Figure 1 The structure diagram of a joint networking system is shown. As Figure 1 shown, the joint networking system 10 includes: a terminal device 11, an aerial base station 12, and a ground base station 13. The terminal device 11, the aerial base station 12, and the ground base station 13 are connected to each other. The terminal device 11, the aerial base station 12, and the ground base station 13 can be connected by a wired method or a wireless method, and the embodiments of the present invention do not limit this.

[0040] The terminal device 11 is used to search for a network cell at the current location, access the first cell corresponding to the aerial base station 12 and the second cell corresponding to the ground base station 13 when the first cell corresponding to the aerial base station 12 and the second cell corresponding to the ground base station 13 are searched, send a first service to the aerial base station 12 corresponding to the first cell, and send a second service to the ground base station 13 corresponding to the second cell; the aerial base station 12 is used to obtain the remaining network carrying capacity of the first cell connected by the terminal device 11 and the remaining network carrying capacity of each second cell included in the first cell, and carry the first service of the terminal device 11; the ground base station 13 is used to carry the second service of the terminal device 11 to perform joint networking based on the terminal device 11, the aerial base station 12, and the ground base station 13.

[0041] Optionally, the terminal device 11 can be a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The aerial base station 12 and the ground base station 13 can be base station devices.

[0042] It should be noted that the terminal device 11 can be a mobile communication terminal device. The aerial base station 12 can be carried by an aerial platform such as a satellite or an aerostat to form a non-terrestrial network and comply with the 3rd generation partnership project (3GPP) NTN protocol standard. The ground base station 13 can be a ground mobile communication base station and can form a terrestrial network.

[0043] Next, a joint networking method provided by an embodiment of the present application will be described with reference to the accompanying drawings. As Figure 2 shown, a joint networking method provided by an embodiment of the present application is applied to an aerial base station, and the method includes S201 - S203:

[0044] S201. Obtain the remaining network carrying capacity of the first cell connected by multiple terminal devices and the remaining network carrying capacity of each second cell included in the first cell.

[0045] Among them, the first cell is the cell corresponding to the aerial base station, and the second cell is the cell corresponding to the activated ground base station.

[0046] It can be understood that the remaining network carrying capacity of the first cell connected by multiple terminal devices and the remaining network carrying capacity of each of the multiple second cells included in the first cell can be obtained through the aerial base station.

[0047] Optionally, after any one of the multiple terminal devices is powered on and enters the access process, cell search can be performed at the current location through any one of the terminal devices. When the signal of the first cell (i.e., the non-terrestrial network cell) is searched, access the first cell, use the first cell as the master node (MN) of any one of the terminal devices, and continue to perform cell search at the current location through any one of the terminal devices to search for the signal of the first target second cell (i.e., the terrestrial network cell).

[0048] Furthermore, obtain the remaining network carrying capacity of the first cell and the remaining network carrying capacity of each of the multiple second cells included in the first cell through the aerial base station corresponding to the first cell, and judge the magnitude relationship between the sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of the multiple second cells and the first preset network carrying capacity.

[0049] S202. When the sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of the multiple second cells is greater than or equal to the first preset network carrying capacity, control the first cell to carry the first service of multiple terminal devices, and control the multiple second cells to carry the second service of multiple terminal devices.

[0050] Among them, the first service includes at least one of the following: voice service and short message service, and the second service includes data service.

[0051] It can be understood that when the sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of the multiple second cells is greater than or equal to the first preset network carrying capacity, the first service and the second service can be sent to the first cell through the aerial base station, and the first service and the second service are carried by the first cell.

[0052] Optionally, when the sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of the multiple second cells is greater than or equal to the first preset network carrying capacity, send the first service to the first cell through multiple terminal devices, so that the first cell carries the first service of multiple terminal devices; send the second service to the multiple second cells through multiple terminal devices, so that the multiple second cells carry the second service of multiple terminal devices.

[0053] S203. When the sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of multiple second cells is less than the first preset network carrying capacity, at least one third cell included in the first cell is activated, the first cell is controlled to carry the first service of multiple terminal devices, and the multiple second cells and at least one third cell are controlled to carry the second service of multiple terminal devices.

[0054] Wherein, the third cell is the cell corresponding to the closed ground base station, and the sum of the remaining network carrying capacity of the first cell, the remaining network carrying capacities of multiple second cells, and the remaining network carrying capacity of at least one third cell is greater than the first preset network carrying capacity.

[0055] Optionally, when the sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of multiple second cells is less than the first preset network carrying capacity, at least one third cell included in the first cell can be activated, and at least one third cell included in the first cell is activated, the first cell is controlled to carry the first service of multiple terminal devices, and the multiple second cells and at least one third cell are controlled to carry the second service of multiple terminal devices.

[0056] The first target second cell can be used as the first secondary node (SN) of any terminal device to establish a dual connection. The first service can be sent to the first cell through any terminal device, the first service of any terminal device is carried by the air base station corresponding to the first cell, and the second service is sent to the first target second cell. The second service of any terminal device is carried by the ground base station corresponding to the first target second cell (that is, the data service can be split to the secondary node through the primary node).

[0057] Exemplarily, Figure 3 As shown, the terminal device 2 located at position B can search for the non-terrestrial network cell corresponding to the air base station and the terrestrial network cell 1 corresponding to the ground base station 1, and use the non-terrestrial network cell corresponding to the air base station as the primary node of the terminal device 2 and the terrestrial network cell 1 corresponding to the ground base station 1 as the first secondary node of the terminal device 2; the terminal device 1 located at position A can only search for the non-terrestrial network cell corresponding to the air base station, so the non-terrestrial network cell corresponding to the air base station can be used as the primary node of the terminal device 1 without adding a secondary node.

[0058] It should be noted that, Figure 3 the air base station in Figure 3The coverage ranges of ground base stations 1 to 9 can achieve good overall geographical coverage and serve as a great supplement to the coverage of the ground mobile network. However, non-terrestrial networks also have problems such as large network latency, small bandwidth, and low rate. Only by organically combining non-terrestrial networks and ground networks can their respective advantages be brought into play to provide users with the best network services. The integration of non-land and land networks (abbreviated as the integrated network) is also an inevitable trend in the development of future new-generation mobile communication networks.

[0059] Exemplarily, the signaling connection of the terminal device 2 can be maintained by the aerial base station, and the voice service can be sent from the terminal device 2 to the aerial base station to carry the voice service of the terminal device 2 through the aerial base station; the data service can be sent from the terminal device 2 to the ground base station 1 to carry the data service of the terminal device 2 through the ground base station 1.

[0060] In a possible way, by having the aerial base station undertake the basic voice service and SMS service of the terminal device, the advantage of wide coverage of the non-land network can be utilized to ensure that the terminal device is always online; by splitting the data service to the secondary node through the master node and having the secondary node undertake the data service, the advantages of large capacity and small latency of the ground network can be utilized to provide the terminal device with high-speed and high-quality broadband Internet access services. By using the dual-connection technology to simultaneously access the non-land network and the land network, the non-land network's wide coverage can be used to ensure that the terminal is always online and provide basic service, and the large capacity and low latency of the land network can be used to provide high-quality data service, thereby providing the optimal network communication solution for users.

[0061] The sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of multiple currently activated second cells is greater than the network carrying capacity required to carry the first service and the second service of multiple terminal devices in the first cell, indicating that the first cell and the currently activated second cells can meet the service requirements of users in the first cell. Then, the services of users can be carried only by the first cell and the currently activated second cells.

[0062] The sum of the remaining network carrying capacity of the first cell and the remaining network carrying capacities of multiple currently activated second cells is less than or equal to the network carrying capacity required to carry the first service and the second service of multiple terminal devices in the first cell, indicating that the first cell and the currently activated second cells cannot meet the service requirements of users in the first cell. Then, at least one third cell that is closed in the first cell can be activated, and the services of users can be jointly carried by the first cell, the currently activated second cells, and the newly activated third cell to meet the service requirements of users in the first cell.

[0063] Using the network of the aerial base station with a wider coverage as the underlying network and the control node, the network of the ground base station can be turned on and off as needed to achieve the goals of energy conservation and improved network operation efficiency.

[0064] In one design, as Figure 4 shown, a joint networking method provided by an embodiment of the present application further includes S301 - S303:

[0065] S301. When a first service of any one of multiple terminal devices is carried by a first cell and a second service of any one of the terminal devices is carried by a first target second cell among multiple second cells, during the movement of any one of the terminal devices, obtain a target neighboring cell corresponding to the first target second cell.

[0066] Optionally, when the first service and the second service of any one of the terminal devices are carried by the first cell and the first target second cell, during the movement of any one of the terminal devices, the terminal device can search for the target neighboring cell corresponding to the first target second cell in real time.

[0067] Exemplarily, as Figure 3 shown, the current serving cells of the terminal device 2 at position B are a non - terrestrial network cell and a terrestrial network cell 1. During the movement of the terminal device 2 towards the terrestrial network cell 2 corresponding to the ground base station 2, the terminal device 2 can report in real time the measurement report corresponding to the cell searched by the terminal device 2. When the terminal device 2 moves to position C, according to the measurement report, it can be determined that the signal strength of the terrestrial network cell 1 searched by the terminal device 2 is less than or equal to a first preset strength value, and the signal strength of the terrestrial network cell 2 is greater than a second preset strength value, which means that at this time the terminal device 2 has entered the edge position between the terrestrial network cell 1 and the terrestrial network cell 2, and the terrestrial network cell 2 is the neighboring cell corresponding to the terrestrial network cell 1.

[0068] S302. When the signal strength of the target neighboring cell is greater than the first signal strength, connect any one of the terminal devices to the target neighboring cell.

[0069] Optionally, when any one of the terminal devices searches for the target neighboring cell, the signal strength of the target neighboring cell can be determined according to the measurement report corresponding to the target neighboring cell. Further, when the signal strength of the target neighboring cell is greater than the first signal strength (i.e., the threshold for adding a secondary node), connect any one of the terminal devices to the target neighboring cell and use the target neighboring cell as the second secondary node of the terminal device.

[0070] Exemplarily, when the signal strength of the terrestrial network cell 2 is greater than the first signal strength, add the terrestrial network cell 2 as the second secondary node of the terminal device 2.

[0071] S303. Control the first target second cell and the target neighboring cell to jointly carry the second service of any one of the terminal devices.

[0072] Optionally, a second service may be sent to the terrestrial base station corresponding to the first target second cell and the terrestrial base station corresponding to the target neighboring cell through any terminal device, so that the terrestrial base station corresponding to the first target second cell and the terrestrial base station corresponding to the target neighboring cell jointly carry the second service of any terminal device.

[0073] In a possible way, by establishing connections between the terminal device and multiple terrestrial base stations, optimal service guarantee during user movement can be achieved, ensuring that the user is always online and reducing or even eliminating handover latency during movement.

[0074] In one design, as Figure 5 shown, a joint networking method provided in an embodiment of the present application, the method in step S303 above specifically includes S401 - S402:

[0075] S401. Determine the first traffic volume ratio corresponding to the second service of any terminal device carried by the first target second cell and the second traffic volume ratio corresponding to the second service of any terminal device carried by the target neighboring cell based on the ratio between the signal strength of the target neighboring cell and the signal strength of the first target second cell.

[0076] Optionally, based on the ratio between the signal strength of the target neighboring cell and the signal strength of the first target second cell, the first traffic volume ratio corresponding to the second service of any terminal device carried by the first target second cell and the second traffic volume ratio corresponding to the second service of any terminal device carried by the target neighboring cell can be determined. The higher the signal strength of the cell, the larger the traffic volume ratio corresponding to the second service of the terminal device carried by the cell.

[0077] Exemplarily, if the signal strength of terrestrial network cell 2 is 10 dBm and the signal strength of terrestrial network cell 1 is 20 dBm, then the traffic volume ratio corresponding to the data service of the terminal device carried by terrestrial network cell 2 is one - third, and the traffic volume ratio corresponding to the data service of the terminal device carried by terrestrial network cell 1 is two - thirds.

[0078] S402. Control the second service of any terminal device with the first traffic volume ratio carried by the first target second cell, and control the second service of any terminal device with the second traffic volume ratio carried by the target neighboring cell.

[0079] Optionally, based on the first traffic ratio and the second traffic ratio, the second traffic with the first traffic ratio is sent to the ground base station corresponding to the first target second cell through any terminal device, and the second traffic with the second traffic ratio is sent to the ground base station corresponding to the target neighboring cell through any terminal device, so as to jointly bear the second traffic by the ground base station corresponding to the first target second cell and the ground base station corresponding to the target neighboring cell (that is, perform on-demand traffic splitting between the first secondary node and the second secondary node according to the signal strength of the ground base station).

[0080] In a possible way, data traffic can be split among different ground base stations according to the signal strength of different ground base stations. In different scenarios, data traffic can be split through different traffic splitting methods, which can achieve efficient and reasonable offloading of user traffic, ensure that the traffic of the terminal device does not drop during movement, the data has no delay, and the user's service experience is optimal.

[0081] In one design, as Figure 6 shown, in a joint networking method provided by an embodiment of the present application, the method further includes S501-S502:

[0082] S501. During the continuous movement of any terminal device, if it is detected that the signal strength of the first target second cell is less than the second signal strength, disconnect the connection between any terminal device and the first target second cell.

[0083] Optionally, during the continuous movement of any terminal device in the first target second cell, the signal strength of the cell can be determined according to the measurement report of the cell. If the signal strength of the first target second cell is less than the second signal strength (i.e., the lowest service threshold), disconnect the connection between any terminal device and the first target second cell.

[0084] Exemplarily, as Figure 3 shown, during the process of the terminal device 2 continuing to move towards the land network cell 2, if the signal strength of the land network cell 1 detected by the measurement report is less than the second signal strength, delete the first secondary node. Finally, the terminal device 2 completely moves to the land network cell 2 (that is, the terminal device is located at position D), and at this time, the terminal device is in dual connection.

[0085] S502. Control the target neighboring cell to bear the second traffic of any terminal device.

[0086] Optionally, data traffic can be sent to the target neighboring cell through any terminal device, so as to bear the data traffic by the target neighboring cell.

[0087] Exemplarily, when the terminal device 2 completely moves to the terrestrial network cell 2, the second secondary node is adjusted to the first secondary node, and the data service of the terminal device 2 is completely taken over by the new first secondary node (i.e., the terrestrial network cell 2). At this time, the handover of the secondary node caused by the movement of the terminal device is completed.

[0088] In a possible way, the transition of the terrestrial network cell can be carried out through multi-connection. First, add the neighboring cell as the secondary node, and then delete the currently served secondary node, which can ensure that the terminal device always has a reliable terrestrial network connection to provide services during the movement, avoiding the traffic drop and data delay problems brought by the conventional cell handover process, and can effectively improve the user experience.

[0089] In one design, as Figure 7 shown, in a joint networking method provided by an embodiment of the present application, a joint networking method provided by an embodiment of the present application, the method includes S601:

[0090] S601. Based on the remaining network carrying capacity of each second cell among the multiple second cells included in the first cell, determine the second target second cell from the multiple second cells, and turn off the second target second cell.

[0091] Wherein, the remaining network carrying capacity of the second target second cell is greater than or equal to the second preset network carrying capacity.

[0092] It can be understood that the remaining network carrying capacity of each second cell among the multiple second cells included in the first cell corresponding to the air base station can be obtained through the air base station, and based on the remaining network carrying capacity of each second cell, the second target second cell is determined from the multiple second cells through the air base station, and the second target second cell is turned off.

[0093] Optionally, the second target second cell corresponding to the ground base station with the largest remaining network carrying capacity (i.e., the second cell with the lowest network load) can be determined from the multiple second cells within the coverage area of the first cell. Further, the users of the second target second cell can be migrated to the first cell or other second cells within the coverage area of the first cell.

[0094] Or, if the second target second cell is a secondary node, the secondary node identity of the second target second cell can be deleted. Further, after the users of the second target second cell are migrated, the second target second cell can be turned off (i.e., the ground base station corresponding to the second target second cell is put into sleep).

[0095] In a possible implementation, turning off some ground base stations with relatively large remaining network carrying capacity (i.e., relatively low network load) can save energy and improve operation efficiency.

[0096] As Figure 8As shown in the figure, when it is detected through the measurement report that the terminal device enters the edge of the serving terrestrial cell (i.e., the first secondary node), neighbor cell measurement is initiated. When a neighbor cell of the serving terrestrial cell is measured and the signal strength of the neighbor cell meets the threshold for adding a secondary node, the neighbor cell is added as the second secondary node, and according to the cell signal strength, data traffic is split between the serving terrestrial cell and the neighbor cell. Further, when it is detected that the signal strength of the serving terrestrial cell is lower than the service threshold, the first secondary node is deleted, and the second secondary node is adjusted to be the first secondary node, and the data traffic is taken over by the new first secondary node. At this time, the secondary node handover is completed.

[0097] The embodiment of the present application provides a joint networking method. The present application mainly uses a non-terrestrial network to establish a primary connection between the terminal device and the aerial base station to keep the user always online and ensure that the user's basic voice and SMS services are not interrupted; and uses a terrestrial network as a supplement to establish a secondary connection between the terminal device and the ground base station to carry the user's data traffic. Compared with the common selective networking methods, it fully considers the collaborative networking problem of the non-terrestrial network and the terrestrial network in the prior art, can make full use of the respective advantages of the two networks, provide the optimal network service for users, and provide a high-speed network service with high speed and low latency for users.

[0098] In different scenarios, the present application realizes the efficient and reasonable offloading of user traffic through different service splitting methods; through the method of transitioning with multiple connections, first adding a neighbor cell as a secondary node and then deleting the serving secondary node, so that the terminal device always has a reliable network connection to provide services during the movement process, and reduces or even eliminates the network handover delay during movement. Thereby avoiding the traffic drop and data delay caused by the conventional cell handover process, and can effectively improve the user experience. In addition, the present application can control the network of the ground base station through the network of the aerial base station, and control the opening and closing of the network of the ground base station in real time according to the requirements, while saving energy and improving the network operation efficiency, and providing the optimal network service for users to ensure that the user is always online.
