The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1 and fig. 2, a redirection method for a communication system 100 is provided in the present embodiment. The communication system 100 includes a first network device 10, a second network device 20, and a terminal device 30. The redirection method comprises the following steps:
011: the second network device 20 sends first frequency point information to the first network device 10, where the first frequency point information includes a first frequency point whose network deployment scheme is to support dual connectivity;
012: the first network device 10 receives the first frequency point information;
013: the first network device 10 generates redirection information according to the first frequency point information;
014: the first network device 10 sends the redirection information to the terminal device 30; and
015: the terminal device 30 receives the redirection information.
With continued reference to fig. 1 and fig. 2, the present embodiment further provides a communication system 100. The communication system 100 includes a first network device 10, a second network device 20, and a terminal device 30. The second network device 20 comprises a communication module 21. Step 011 can be implemented by the communication module 21. The first network device 10 comprises a communication unit 11 and a processing circuit 12. Steps 012 and 014 can be implemented by the communication unit 11, and step 013 can be implemented by the processing circuit 12. The terminal device 30 includes a communication element 31. Step 015 may be implemented by the communication element 31.
That is, the communication module 21 is configured to send first frequency point information to the first network device 10, where the first frequency point information includes a first frequency point whose networking scheme is to support dual connectivity. The communication unit 11 is configured to receive the first frequency point information. The processing circuit 12 is configured to generate redirection information according to the first frequency point information. The communication unit 11 is also used to send redirection information to the terminal device 30. The communication element 31 is used to receive redirection information.
The first network device 10 may be a wireless communication facility for implementing a certain mobile communication technology, for example, a wireless communication facility for implementing a second generation mobile communication technology (2G) or a wireless communication facility for implementing a third generation mobile communication technology (3G). The second network device 20 may be a wireless communication facility for implementing another mobile communication technology, for example, may be a wireless communication facility for implementing a fourth generation mobile communication technology (4G), or the like. The Terminal device 30 may also be referred to as a User Equipment (UE), or may be referred to as a Mobile Station (MS), a Mobile Terminal device 30(Mobile Terminal), or the like. For example, the terminal device 30 may be a mobile telephone (or "cellular" telephone), a computer with mobile network access functionality, or the like; for example, the terminal equipment 30 may also be portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices that exchange voice and/or data with a radio access network; for example, the terminal Device 30 may also be a Device to Device (D2D) enabled terminal Device 30 or a Machine to Machine (M2M) enabled terminal Device 30, etc., and is not limited herein.
Specifically, when the first network device 10 needs to initiate a redirection request to the terminal device 30, the communication module 21 of the second network device 20 sends the first frequency point information of the second network device 20 to the first network device 10. The first frequency point information comprises a first frequency point which adopts a network arrangement scheme to support double connection. The number of the first frequency points in the first frequency point information may be one or more, and is not limited herein. In the second network device 20, the cell (4G) using the network deployment scheme to support the first frequency point of the dual connectivity has a frequency point configured with 5G for the terminal device 30 accessing to the cell, so that the terminal device 30 can use the capability of the 5G wireless communication network. A cell (4G) that uses the networking scheme and does not support the first frequency point of dual connectivity does not have the capability of configuring a 5G frequency point for the terminal device 30 accessing the cell. The network arrangement schemes of which first frequency points in the 4G wireless communication network support dual connection, and the network arrangement schemes of which first frequency points do not support dual connection are determined by network operators. For example, a network operator provides 10000 first frequency points, and on a 4G base station at a position a, three first frequency points of 100, 101, and 102 are arranged, wherein only 100 first frequency points support dual connectivity. After the network is configured, the 4G base station of the second network device 20 knows each first frequency point of the 4G base station and the network deployment scheme of each first frequency point. After receiving the information request, the second network device 20 may send the first frequency point 100 supporting dual connectivity to the first network device 10. It should be noted that, in other embodiments, the dual connectivity may refer to dual connectivity (i.e., EN-DC) between 4G and 5G with the core network being a 4G core network and the anchor point being a 4G base station, or may refer to dual connectivity (i.e., NE-DC) between 4G and 5G with the core network being a 5G core network and the anchor point being a 5G base station, or may refer to dual connectivity (i.e., nen-DC) between 4G and 5G with the core network being a 5G core network and the anchor point being a 4G base station after upgrade, and the like, which is not limited herein. Even, dual connectivity may also refer to dual connectivity between any other two wireless communication networks, such as dual connectivity between 4G and 6G, dual connectivity between 5G and 6G, and the like, without limitation herein.
After the communication unit 11 of the first network device 10 receives the first frequency point information sent by the second network device 20, the processing circuit 12 in the first network device 10 may generate redirection information for the first frequency point supporting dual connectivity according to the networking scheme. The communication unit 11 sends the redirection information to the terminal device 30, and the terminal device 30 can perform redirection according to the redirection information after receiving the redirection information. For example, after receiving the redirection message sent by the first network device 10, the terminal device 30 releases the connection with the first network device 10, and sends a connection request to the second network device 20 corresponding to the first frequency point according to the first frequency point carried in the redirection message, so as to redirect to the second network device 20.
It can be understood that when the communication network corresponding to the first network device 10 has signal difference, network congestion, or a network policy needs to be changed, the first network device 10 provides the terminal device 30 with the relevant frequency point information, so that the terminal device 30 can perform redirection. However, when the terminal device 30 performs redirection, it is not known which frequency points of the frequency points that are sent to it by the first network device 10 support dual connectivity, so that the terminal device 30 may redirect to a frequency point that does not support dual connectivity, resulting in a network residence failure of the terminal device 30.
In the redirection method and the communication system 100 according to the embodiment of the present application, the first network device 10 sends redirection information, which is sent by the second network device 20 and generated for the first frequency point supporting dual connectivity according to the networking scheme, to the terminal device 30, so that the terminal device 30 can redirect to a target frequency point preferentially according to the redirection information, and thus, the probability that the terminal device 30 successfully accesses to another wireless communication network through dual connectivity on one wireless communication network can be greatly improved.
Referring to fig. 2 and 3, in some embodiments, the redirection method further includes:
016: the first network device 10 sends an information request to the second network device 20;
017: second network device 20 receives the information request.
0111: the second network device 20 sends the first frequency point information to the first network device 10 according to the information request.
Referring to fig. 2 and fig. 3, in some embodiments, step 016 can be implemented by the communication unit 11, and steps 017 and 0111 can be implemented by the communication module 21.
That is, the communication unit 11 is also configured to send an information request to the second network device 20. The communication module 21 is further configured to receive the information request, and send the first frequency point information to the first network device 10 according to the information request.
Specifically, when the first network device 10 needs to initiate a redirection request to the terminal device 30, the communication unit 11 of the first network device 10 first sends an information request to the second network device 20 to request the second network device 20 to send the first frequency point information to the second network device 20. After receiving the information request, the second network device 20 sends the first frequency point information to the first network device 10 according to the information request. After the second network device 20 receives the information request, the second network device 20 sends the first frequency point information to the first network device 10, which can avoid the problem that the transmission overhead between the first network device 10 and the second network device 20 is increased when the first network device 10 does not need the first frequency point information, on the one hand, the second network device 20 can send the first frequency point information to the first network device 10 in time, and on the other hand, the second network device 20 can send the first frequency point information to the first network device 10 in time, so that the terminal device 30 can be redirected in time.
Fig. 4 is a schematic diagram of information interaction between first network device 10 and second network device 20 according to an embodiment. As shown in fig. 2 and 4, when the first network device 10 is a wireless communication facility for implementing a second generation mobile communication technology (2G), the first network device 10 includes a 2G base station (GERAN BSS) and a GPRS service Support Node (SGSN), in which case the communication unit 11 may include both a communication unit located in the 2G base station and a communication unit located in the GPRS service Support Node, and the processing circuit 12 may include both a processing circuit located in the 2G base station and a processing circuit located in the GPRS service Support Node; when the first network device 10 is a wireless communication facility for implementing the third generation mobile communication technology (3G), the first network device 10 includes a 3G base station (UTRAN RNC) and a GPRS service Support Node (Serving GPRS Support Node), the communication unit 11 may include both a communication unit located in the 3G base station and a communication unit located in the GPRS service Support Node, and the processing circuit 12 may include both a processing circuit located in the 3G base station and a processing circuit located in the GPRS service Support Node. The second network device 20 may be, for example, a wireless communication facility for implementing a fourth generation mobile communication technology (4G), and the second network device 20 includes a Mobility Management Entity (MME) and a 4G base station (E-UTRAN enodeB, also called LTE base station), in which case the communication module 21 may include a communication module located in the MME and a communication module located in the 4G base station.
The following describes information interaction between the first network device 10 and the second network device 20 by taking the first network device 10 as a wireless communication facility for implementing the second generation mobile communication technology (2G) and the second network device 20 as an example for implementing the fourth generation mobile communication technology (4G).
As shown in fig. 2 and fig. 4, when the first network device 10 needs to initiate a redirection REQUEST to the terminal device 30, the 2G base station first sends an INFORMATION REQUEST signaling (RAN INFORMATION REQUEST) to the GPRS service support node in a format of DIRECT INFORMATION TRANSFER (DIRECT INFORMATION TRANSFER). After receiving the INFORMATION request signaling, the GPRS service support node forwards the INFORMATION request signaling to the mobility management entity in a format of RAN INFORMATION RELAY (RAN INFORMATION RELAY). After receiving the INFORMATION request signaling, the MME sends the INFORMATION request signaling to the 4G base station through a format of MME direct INFORMATION TRANSFER (MME DIRECT INFORMATION TRANSFER). After receiving the INFORMATION request signaling, the 4G base station sends a signaling (RAN INFORMATION) containing the first frequency point INFORMATION to the MME through a format of direct INFORMATION TRANSFER (enb INFORMATION TRANSFER) of the 4G base station according to the INFORMATION request signaling. After receiving the signaling containing the first frequency point INFORMATION, the MME forwards the signaling containing the first frequency point INFORMATION to the GPRS service support node in a format of RAN INFORMATION RELAY (RAN INFORMATION RELAY). After receiving the signaling containing the first frequency point INFORMATION, the GPRS service support node sends the signaling containing the first frequency point INFORMATION to the 2G base station through a format of DIRECT INFORMATION TRANSFER (DIRECT INFORMATION TRANSFER).
It can be understood that after the 2G base station or the 3G base station sends the information request to the 4G base station, the signaling sent by the 4G base station to the 2G base station or the 3G base station usually does not include the first frequency point used by the 4G wireless communication technology, nor does it include the network deployment scheme corresponding to the first frequency point. In the redirection method of the embodiment of the application, after receiving an information request sent by a 2G base station or a 3G base station, a 4G base station adds both a first frequency point and a network deployment scheme corresponding to the first frequency point to a signaling, so that the 2G base station or the 3G base station can know the first frequency point of a 4G wireless communication network and a corresponding network deployment condition.
Referring to fig. 2 and 5, in some embodiments, the first frequency point information further includes that the network deployment scheme is the first frequency point that does not support dual connectivity; the step 013, in which the first network device 10 generates redirection information according to the first frequency point information, includes:
018: the first network device 10 selects the networking scheme as at least one first frequency point supporting dual connectivity from the first frequency point information.
With continued reference to fig. 2 and 5, in some embodiments, step 018 may be implemented by the processing circuit 12.
That is, the processing circuit 12 is further configured to select at least one first frequency point supporting dual connectivity as the networking scheme from the first frequency point information.
Specifically, in the redirection process, the second network device 20 may send its own first frequency point information to the first network device 10, where the first frequency point information may include a first frequency point whose network deployment scheme is to support dual connectivity and a second frequency point whose network deployment scheme is not to support dual connectivity. The first network device 10 may select at least one first frequency point from the first frequency point information for generating redirection information. In an example, the second network device 20 may add a corresponding attribute field to each first frequency point, so as to indicate to the first network device 10 whether the first frequency point supports dual connectivity, so that the subsequent processing circuit 12 selects a networking scheme from the first frequency point information as at least one first frequency point supporting dual connectivity. For example, an attribute field endflag may be added to each first bin to indicate whether the first bin supports dual connectivity, and endflag may be set to 1 to indicate that the first bin supports dual connectivity, and endflag may be set to 0 to indicate that the first bin does not support dual connectivity. Then, after the first network device 10 receives the first frequency point information, the first network device 10 may find the first frequency point with endc _ flag equal to 1 in the first frequency point information as the target frequency point. Of course, in other examples, an endc _ flag ═ 1 may be set to indicate that the first frequency point does not support dual connectivity, and an endc _ flag ═ 0 indicates that the first frequency point supports dual connectivity, and a specific numerical value corresponds to the network deployment scheme, which may be determined by a developer, or a standard builder introduces a 3GPP standard, and then the developer implements the first frequency point according to the 3GPP standard, and the like, without limitation.
Referring to fig. 2 and 6, in some embodiments, the redirection method further includes:
019: the terminal device 30 sends second frequency point information to the first network device 10, where the second frequency point information includes a second frequency point that can be used by the terminal device 30;
020: the first network device 10 receives the second frequency point information;
0181: the first network device 10 selects at least one first frequency point from the first frequency point information and the second frequency point information, the network arrangement scheme of the at least one first frequency point is to support dual connection, and the at least one first frequency point and the second frequency point are the same frequency point;
step 015 the receiving, by the terminal device 30, the redirection information includes:
0151: the terminal device 30 receives redirection information which is sent by the first network device 10 and is generated for a first frequency point which supports dual connection and is the same as a second frequency point according to a network deployment scheme;
the redirection method further comprises the following steps:
021: the terminal device 30 redirects the first frequency point supporting dual connection and being the same frequency point as the second frequency point according to the network deployment scheme.
With continuing reference to fig. 2 and fig. 6, in some embodiments, step 019, step 0151 and step 021 can be implemented by the communication component 31, step 020 can be implemented by the communication unit 11, and step 0181 and step 0131 can be implemented by the processing circuit 12.
That is, the communication element 31 is also configured to transmit second frequency point information to the first network device 10, the second frequency point information including a second frequency point that can be used by the terminal device 30. The communication unit 11 is further configured to receive second frequency point information. The processing circuit 12 is further configured to select at least one first frequency point from the first frequency point information and the second frequency point information, where the network deployment scheme of the at least one first frequency point is to support dual connectivity, and the at least one first frequency point and the second frequency point are the same frequency point. The communication element 31 is further configured to receive redirection information, which is sent by the first network device 10 and generated for the first frequency point that supports dual connectivity and is the same as the second frequency point according to the network deployment scheme, and redirect the first frequency point that supports dual connectivity and is the same as the second frequency point according to the network deployment scheme.
It can be understood that, in the first frequency point information sent by the second network device 20, not all the first frequency points can be used by the terminal device 30, and therefore the first network device 10 needs to receive the second frequency point information that the terminal device 30 sent by the terminal device 30 can use, the processing circuit 12 selects, from the first frequency point information and the second frequency point information, at least one first frequency point whose network deployment scheme is to support dual connectivity and is the same frequency point as the second frequency point, and generates redirection information for at least one first frequency point whose network deployment scheme is to support dual connectivity and is the same frequency point as the second frequency point. The terminal device 30 receives redirection information that is generated for the first frequency point that supports dual connectivity and is the same frequency point as the second frequency point according to the networking scheme and is sent by the first network device 10, and redirects according to the redirection information. The number of the second frequency points in the second frequency point information may be one or more, which is not limited herein. For example, the first frequency point information sent by the second network device 20 includes three first frequency points 100, 101, and 102, where the first frequency point 100 and the first frequency point 101 both support dual connectivity. And the second frequency point information sent by the terminal device 30 includes two second frequency points 101 and 103, and the processing circuit 12 determines, from the three first frequency points 100, 101, and 102, that the first frequency point 101 is a target frequency point that can support dual connection and can be used by the terminal device 30. After the processing circuit 12 obtains the target frequency point, the processing circuit 12 generates redirection information according to the target frequency point, and the redirection information is sent to the terminal device 30 by the communication unit 11. After receiving the redirection information, the terminal device 30 may redirect according to the target frequency point, and after the terminal device 30 redirects to the target frequency point, the second network device 20 may determine whether to configure the terminal device 30 in the dual connectivity state according to the network requirement of the terminal device 30. In an example, when the terminal device 30 is in a state of playing a movie, playing a game, or the like, the terminal device 30 needs to have a faster and better network speed, and at this time, the second network device 20 may configure the terminal device 30 to a dual connection state, and at this time, the network connection of the terminal device 30 is changed from the original single connection channel to the dual connection channel, so that the network speed is increased; in another example, when the terminal device 30 is in a state of voice call, web browsing, or the like, the amount of data required by the terminal device 30 is small, and at this time, the second network device 20 may not configure the terminal device 30 to the dual connection state. Of course, in other examples, the configuration policy may be that the second network device 20 configures the dual connectivity for the terminal device 30 as long as the terminal device 30 is redirected to the network corresponding to the target frequency point that can be used by the terminal device 30. The specific configuration policy may be determined by a network operator according to an actual application scenario, and is not limited herein.
Referring to fig. 2 and fig. 7, in some embodiments, after the step 015 of receiving, by the terminal device 30, redirection information, the redirection method further includes:
022: the terminal equipment 30 determines that the network deployment scheme is that a first frequency point which supports double connection and is the same as a second frequency point is a target frequency point and the second frequency point is a frequency point which can be used by the terminal equipment 30 according to the redirection information and the second frequency point; and
023: and the terminal equipment 30 redirects according to the target frequency point.
With continued reference to fig. 2 and 6, in some embodiments, the terminal device 30 further includes a processing chip 32. Step 022 may be implemented by the processing chip 32 and step 023 may be implemented by the communication element 31. That is, the processing chip 32 is configured to determine, according to the redirection information and the second frequency point, that the first frequency point, which is in the same frequency point as the second frequency point and supports dual connection, of the network deployment scheme is a target frequency point, and the second frequency point is a frequency point that can be used by the terminal device 30. The communication element 31 is also used for the terminal device 30 to perform redirection according to the target frequency point.
It can be understood that not all of the first frequency points in the first frequency point information sent by the second network device 20 can be used by the terminal device 30. Therefore, after the terminal device 30 receives the redirection information, it can determine, according to the redirection information and the second frequency point that can be used by the terminal device 30, that the first frequency point, which supports dual connection and is the same as the second frequency point, of the network deployment scheme is the target frequency point. For example, the first frequency point information sent by the second network device 20 includes three first frequency points 100, 101, and 102, where the first frequency point 100 and the first frequency point 101 both support dual connectivity. The processing circuit 12 of the first network device 10 generates redirection information according to the first frequency points 100 and 101 that support dual connectivity, and the communication unit 11 sends the redirection information to the terminal device 30. The communication element 31 of the terminal device 30 receives the redirection information and transmits the redirection information to the processing chip 32. The processing chip 32 obtains the two first frequency points 100 and 101 from the redirection information, and determines that the first frequency point 101 is a target frequency point that supports dual connectivity and can be used by the terminal device 30 by combining the second frequency points 101 and 103 that can be used by the terminal device 30 itself. The terminal device 30 can redirect the target frequency point preferentially, so that the probability that the terminal device 30 successfully accesses to another wireless communication network through dual connection on one wireless communication network can be greatly improved.
In summary, in the redirection method, the first network device 10, the second network device 20 and the communication system 100 according to the embodiments of the present application, the first network device 10 sends redirection information, which is sent by the second network device 20 and is generated for a first frequency point supporting dual connectivity according to a networking scheme, to the terminal device 30, so that the terminal device 30 can redirect to a target frequency point preferentially according to the redirection information, and thus the probability that the terminal device 30 successfully accesses to one wireless communication network through dual connectivity can be greatly improved.
