a) Inter-system cell association information; the inter-system cell association information is used for representing association between two cells of the inter-system (i.e. two network systems of different systems), and the two associated cells can perform cell selection or reselection at the same time. For example: the terminal is currently registered in the 5G cell 1 and the 6G cell 1, when the terminal needs to reselect from the 5G cell 1 to the 5G cell 2, the association between the 5G cell 2 and the 6G cell 2 can be known according to the association relation, and the terminal can directly reselect from the 6G cell 1 to the 6G cell 2 without measuring the 6G cell.
b) Selectable cell identification information; for indicating cells that the terminal may select during cell selection and/or reselection.
c) Different system double resident indication information of the selectable cell; for indicating whether the selectable cell supports dual camping of the heterogeneous system when the terminal is selecting and/or reselecting the cell.
Optionally, the terminal supporting dual camping of the different system, or the terminal having performed dual registration in the different system, or the terminal having registered service or protocol data unit (Protocol Data Unit, PDU) session in both systems at the same time, can reselect to the cell supporting dual camping of the different system preferentially when performing cell reselection through the different system dual camping indication information.
In one embodiment, for example, in a specific embodiment of the inter-system cell association information, a first cell of 5G and a second cell of 6G have an association relationship, that is, terminals residing in both 5G and 6G, if reselecting to the first cell of 5G, the terminals may reselect 6G to the second cell at the same time.
The association relation of the application means that the 5G cell and the 6G cell are arranged in a co-station way, the coverage is the same or similar, and when the 5G signal is good, the 6G signal can be considered to be good. Meanwhile, the 5G cell transmits system information necessary for accessing the 6G to the terminal, when the terminal resides in the 5G, the 6G can be considered as a service cell, and when connection is to be established, the terminal can directly access the 6G cell.
In this embodiment of the present application, optionally, step 101 includes one of the following:
102, receiving the system information broadcast by the first network node or the second network node;
step 103, sending signaling to the first network node or the second network node, and receiving the system information fed back by the first network node or the second network node according to the signaling.
In one embodiment, step 102 obtains the system information through a broadcast message, for example: the terminal acquires broadcasted system information from the 5G cell, the 5G cell broadcasts all information required by accessing the 6G cell, the 6G cell does not need to broadcast the system information, only serves as NSA (Non-independent networking) access, all the broadcasted messages and the system information are obtained through the 5G cell, and the 6G cell only broadcasts MIB (Master Information Block, main system module) and a synchronizing signal. Alternatively, for example: the terminal acquires the broadcasted system information from the 6G cell, the 6G cell broadcasts all information needed by the 5G cell, and the 5G cell does not need to broadcast the system information.
In one embodiment, step 103 obtains the system information through signaling. For example: the terminal acquires the system information from the 5G cell, the terminal resides in the 5G cell, the terminal sends signaling to the 5G cell, reports the 6G cell which wants to reside, and acquires all information needed by the 6G cell from the 5G cell. Alternatively, for example: the terminal acquires the system information from the 6G cell, the terminal resides in the 6G cell, the terminal sends signaling to the 6G cell, the 5G cell which wants to reside in is reported, and all information required by the 5G cell to reside in is acquired from the 6G cell.
Optionally, in step 103, the terminal may first enter a connection state and then request system information of another network node (e.g. 6G cell) from the first network node or the second network node (e.g. 5G cell); alternatively, the terminal requests system information of another network node (e.g., a 6G cell) through random access in an idle state or a deactivated state of the first network node or the second network node (e.g., a 5G cell). In the random access information, network system information (system information indicating which network systems are requested, e.g., for requesting 5G or 6G) and a system information identification ID may be carried.
In summary, the terminal receives the system information of the second network node through the first network node or receives the system information of the first network node through the second network node by the method of step 102 or step 103 as above, for example: the system information of the 6G cell is obtained through the 5G cell, the 6G cell is accessed only when the 6G is accessed, the terminal only resides in the 5G cell at ordinary times, the system information and the broadcast message are received from the 5G cell, and the time and the power consumption for receiving the system information by the terminal are saved.
Optionally, the method further comprises:
and 104, performing dual-resident cell reselection according to the system information.
According to the embodiment of the application, the terminal can execute the double-resident cell reselection according to the system information without restarting the heterogeneous system search network, so that the reselection time is shortened, and the user experience is improved; meanwhile, the user experience is improved, and meanwhile, the processing of the terminal is simplified. Optionally, after receiving the system information, the terminal may obtain inter-system cell association information according to the system information, so as to obtain association relations between cells of different network systems, and when performing dual-resident cell reselection, the terminal may learn, only by combining with the association relation, a target cell that needs to be reselected by one network node according to a reselected target cell of another network node. For example: 5G cell 1 is associated with 6G cell 1, 5G cell 2 is associated with 6G cell 2; the terminal currently resides in the 5G cell 1 and the 6G cell 1, when the cell reselection is needed, the 5G cell 1 needs to be reselected to the 5G cell 2, the 6G cell is not needed to be measured, and the 6G cell 1 can be reselected to the 6G cell 2 at the same time according to the association relation.
Specifically, the step 104 includes:
and 105, determining the related information of the cells of the different systems according to the system information.
In the embodiment of the application, the terminal receives the inter-system cell association information sent by the network equipment, and can acquire the association information between the first network node cell and the second network node cell. That is, the terminal can determine the association between the 5G cell and the 6G cell according to the system information, and the terminal refers to the association when reselecting the cell, so that the terminal does not need to measure the 6G signal intensity.
Step 106, if the terminal reselects from the first network node to a third network node, reselecting from the second network node to a fourth network node according to the inter-system cell association information;
wherein the third network node and the fourth network node are associated.
It should be noted that, the meaning of the association may be understood that the terminal obtains from the system information that a certain 5G cell is related to a certain 6G cell.
In one embodiment, in step 106, if the terminal reselects from the first network node (e.g., a cell under 5G) to the third network node (e.g., B cell under 5G), according to the inter-system cell association information, reselects from the second network node (e.g., a cell under 6G) to the fourth network node (e.g., B cell under 6G), and the signal strength of the 6G network is not required to be measured; here, an a cell under 5G is associated with an a cell under 6G, and a B cell under 5G is associated with a B cell under 6G. According to the embodiment of the application, the dual residence of the cells is realized according to the synchronous reselection of the inter-system cell associated information.
In a specific embodiment, when the terminal reselects a 5G cell, the terminal ranks according to the R criteria, and the terminal selects a certain 5G cell according to the ranking. If the terminal has the corresponding relation between the 5G cell and the 6G cell, the terminal takes the 6G cell corresponding to the 5G cell as a service cell.
In another embodiment, when a terminal takes one 5G cell as a serving cell, the 6G cell associated with the terminal is also taken as the serving cell.
In another embodiment, when the terminal resides in 1 5G cell, if a service related to 6G is to be initiated, the terminal accesses the 6G cell associated with the 5G cell. In the prior art, the terminal needs to make different system measurements, obtain the optimal 6G cell by sequencing, and then reselect the 6G cell. Compared with the prior art, the speed of the terminal accessing the 6G cell can be faster.
In another embodiment, when the terminal considers that one 5G cell satisfies the cell selection S criterion, the terminal considers that the 6G cell associated with the 5G cell also satisfies the cell selection S criterion.
In an embodiment of the present application, optionally, the method further includes:
step 107, according to the system information, sending a registration request message to the first network node and/or the second network node under the condition that the first network node and the second network node support dual access; the registration request message comprises service information requested by the terminal at the first network node and service information requested by the terminal at the second network node;
Step 108, receiving network capability related information sent by the first network node and/or the second network node, where the network capability related information includes service capability information of the first network node and service capability information of the second network node.
Here, the terminal receives network capability related information, which is used to indicate that the network device supports dual access, i.e., the terminal can access the network through the 5G network node and the 6G node at the same time.
In this embodiment, the terminal may perform dual access between the first network node and the second network node according to the system information. In particular, the terminal may send a registration request to the first network node and/or the second network node, where the registration request includes service related information requested by the terminal. For example: the terminal sends the registration request message to a first network node, wherein the registration request message comprises: the terminal needs the service information requested in the first network node and the service information requested in the second network node.
Or the terminal sends the registration request message to the second network node, wherein the registration request message comprises: the terminal needs the service information requested in the second network node and the service information requested in the first network node.
Or, the terminal sends a registration request message to the first network node and the second network node respectively, for example: the terminal sends a first registration request message to a first network node, wherein the first registration request message comprises service information requested by the terminal in the first network node, and the first registration request message also comprises service information requested by the terminal in the second network node; the terminal sends a second registration request message to the second network node, wherein the second registration request message comprises service information requested by the terminal in the second network node, and the second registration request message also can comprise service information requested by the terminal in the first network node. For example: three processing methods are included in sending the registration request in step 107, including:
mode one: and sending the service information requested by the terminal at the 5G network node and the service information requested by the terminal at the 6G node to the 5G network node. I.e. the terminal sends a registration request to the 5G network node, wherein not only the request of 5G needs to be carried, but also the content of 6G needs to be carried, i.e. the first target service applied in 5G and the second target service applied in 6G are described in the registration request.
Mode two: and sending the service information requested by the terminal at the 5G network node and the service information requested by the terminal at the 5G network node to the 6G node.
Mode three: and sending the service information requested by the terminal at the 5G network node to the 5G network node, and sending the service information requested by the terminal at the 6G node.
Optionally, if the terminal sends the registration request to the 5G network node and the 6G node at the same time, service information requested by the terminal at the 5G network node is sent through the 5G network node, and service information requested by the terminal at the 6G node is sent through the 6G node. Or sending the service information requested by the terminal at the 5G network node and the service information requested by the 6G node through the 5G network node; and sending the service information requested by the terminal at the 6G node and the service information requested by the 5G network node through the 6G node.
In step 107, the terminal sends a NAS (non access stratum) registration request to the node of 5G and/or 6G, where the NAS registration request carries the requested service, for example, requested NSSAI information, where the requested NSSAI information includes target network slice information selected by the UE. It should be noted that there may be a difference between services supported by 5G and 6G, i.e., some services may be supported by only 5G or only 6G.
After the registration request is sent in step 107, network capability related information fed back by the network device is also received, where the network capability related information includes service capability information allowed by the current node and may also include service capability information allowed by another node.
Optionally, the network capability related information may further include a network format corresponding to the network node, for example: the first network node is a 5G network node, the second network node is a 6G network node, and the terminal sends a registration request message to the 5G network node, wherein the registration request message comprises service information requested in the 5G network and service information requested in the 6G network. The 5G network node feeds back the network capability related information to the terminal, wherein the information comprises the network type (namely 5G) and the supported service capability of the 5G network node, and further comprises the network type (namely 6G) and the supported service capability of the 6G network node.
For example, in the case that the 5G network node feeds back the supporting slice a/B, and the 6G node feeds back the supporting slice B/C/D, the feedback information in the above-mentioned mode one is: supporting slice A/B in the 5G network node; the feedback information in the second mode is: supporting slice B/C/D in the 6G node; the feedback information in the third mode is: slice A/B is supported in 5G and slice B/C/D is supported in 6G.
In an embodiment of the present application, optionally, the method further includes:
step 109, sending terminal capability information to the first network node and/or the second network node;
The terminal capability information is used for indicating that the terminal supports or does not support dual access.
It should be noted that, step 109 may be performed at any time after the terminal and the network device are connected.
In this embodiment, it may be determined according to the terminal capability information that the terminal supports or does not support dual access of the first network node and/or the second network node, for example, the terminal supports dual access in the 5G network and the 6G network, and then the terminal reports the capability to the 5G network node and the 6G network node, where the 5G network node and the 6G network node may determine that the terminal supports dual access according to the terminal capability, and then the terminal is allowed to perform dual connection between the 5G network node and the 6G network node.
In an embodiment of the present application, optionally, the method further includes:

Optionally, step 110 described above includes one of the following:
and a step a of sending the connection establishment request to the first network node if the first service is a service supported by the first network node.

And d, if the first service is the service supported by the first network node and the second network node, respectively sending the connection establishment request to the first network node and the second network node.
For example: the traffic supported by the first network node represents traffic supported by the 5G network node and the traffic supported by the second network node represents traffic supported by the 6G node. In step a, when a service is initiated by the terminal, if the first service is a service supported by the 5G network node only, the connection establishment request is sent to the 5G network node. In step b, when the terminal has service initiation, if the first service is the service supported by the 6G node only, the connection establishment request is sent to the 6G node.
In step c, when the terminal has a service initiation, if the first service is a service supported by both the 5G network node and the 6G network node, the terminal selects according to a predetermined rule (first rule), for example, the 5G signal is better than a certain condition (for example, greater than a threshold value), and preferentially selects the 5G network node to establish connection, otherwise, selects the 6G network node to establish connection. Or the terminal defaults to be initiated at the 5G network node or the 6G node, or the terminal autonomously selects to be initiated at the 5G network node or the 6G node.
In step d, when the terminal has service initiation, if the first service is a service supported by both the 5G network node and the 6G network node, the terminal initiates connection at the 6G node and the 5G network node respectively and simultaneously, and the 5G network node is a 5G network node.
In this embodiment of the present application, optionally, in a case where the terminal is in a dual idle state (idle), the method further includes:
step 111, receiving paging configuration information, wherein the paging configuration information comprises a paging identifier;
step 112, receiving paging information sent by the core network according to the paging identification;

For example, the 5G network node sends a paging identity for 5G network access to the terminal, and the 6G node sends a paging identity for 6G network access to the terminal. And the terminal receives the paging message under the 5G network node or the 6G network node according to the paging identification. Step 112 to step 113, the terminal realizes accessing to the corresponding network node according to the received paging message. For example, after receiving the paging message, the terminal performs 5G cell access or 6G cell access according to the paging message.
In this embodiment of the present application, optionally, the paging message includes at least one of the following information 1) to 4):
1) The system information corresponding to the paging message; the system information is used for indicating the network system corresponding to the paging message, for example, for indicating at least one of the following items corresponding to the paging message: 5G paging, 6G paging.
2) Network identification information corresponding to the paging message; the network identification information is used to distinguish between the first network node identification or the second network node identification, for example, it may be a 5G identification or a 6G identification.
3) Service type information; the service type information is used to represent the type of service supported by the network node, e.g. to determine whether the current node supports 5G services or 6G services.
4) Slice information. For example, slice information includes, but is not limited to: slice identification, slices supporting traffic of the first network node and/or the second network node, etc.
In this embodiment, after receiving the paging message, the terminal may determine an access network node according to the paging message, for example: the paging message comprises a 5G cell identifier, and a 5G cell indicated by the 5G cell identifier supports a first service, so that the terminal accesses a 5G cell corresponding to the 5G cell identifier; or the paging message includes a 6G cell identifier, and if the 6G cell indicated by the 6G cell identifier supports the first service, the terminal accesses the 6G cell corresponding to the 6G cell identifier.
In this embodiment of the present application, in a case where the terminal is in a connection state of the first network node and is in an inactive state of the second network node, the method optionally further includes:

In the above case, the terminal may directly receive the second service data sent by the first network node. For example: when the terminal is in a 5G network node connection state, receiving second service data of the 6G node at the 5G network node; or when the terminal 6G node is in a connection state, receiving second service data of the 5G network node at the 6G node.
Or, in the case that the terminal is in a connection state of the first network node and is in an inactive state of the second network node, the method further includes:
Step 115, receiving a radio resource control RRC message sent by the first network node, where the RRC message is generated by triggering by the second network node;
step 116, initiating access to the second network node according to the RRC message;
step 117, receiving the second service data in case of establishing a connection with the second network node;
wherein the second service data is related data of a second service supported by the second network node.
In this embodiment, the second network node is in an inactive state, at this time, the second network node triggers to generate an RRC message, and the RRC message is forwarded by the first network node to the terminal, and according to the RRC message, the terminal initiates access to the second network node, establishes connection, and after the establishment is successful, receives second service data sent by the second network node.
For example; when the 6G service arrives, if the current terminal is in an inactive state at the 6G network node, the 6G network node can trigger an RRC message instead of forwarding service data, and the RRC message is forwarded to the terminal through the 5G network node to request the terminal to initiate access to the 6G network node.
Optionally, the selection of the above-mentioned step 114, or the two processing manners from step 115 to step 117 depends on whether the currently initiated service data is carried on the first network node or the second network node.

For example, when the first network node is a 5G network node and the second network node is a 6G network node, in step 307, when the terminal is in a 5G network node connection state and a service of the 6G node arrives, if the 6G node is in an inactive state, the 6G node forwards the downlink arriving data (second service data) to the 5G network node, and the 5G network node sends the second service data to the terminal.
In another specific embodiment, when the first network node is a 5G network node and the second network node is a 6G node, in step 308, when the terminal is in a 5G network node connection state and a service of the 6G node arrives, if the 6G node is in an inactive state, the 6G node does not forward data, but triggers an RRC message, the 5G network node receives the RRC message sent by the 6G node, and the 5G network node sends the RRC message to the terminal to establish a connection with the terminal.
It should be noted that the selection of the two methods in step 307 or step 308 depends on whether the currently initiated service has a bearer on the first network node or the second network node.
According to the embodiment of the application, the first network node can send the system information of the first network node and the system information of the second network node to the terminal, so that the system information of two different network nodes is sent to the terminal under one network node, the terminal can carry out simultaneous residence or access of the two system network nodes according to the specific content of the system information, the construction cost is saved, the time and the power consumption for the terminal to receive the system information are saved, and the problem of great reconstruction of original network equipment can be avoided.
