Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
When a roaming subscriber leaves the coverage area of a certain operator, it may enter an area with a plurality of alternative roaming operators. When a roaming user is active in the area, it is often necessary to select a network of a roaming operator from a plurality of selectable roaming operators for network handover.
Typically, a roaming user is not aware of multiple alternative roaming operators, and often chooses a roaming operator at will among the multiple alternative roaming operators. Even if there is a network in which a roaming operator is willing to provide service preference for the roaming user to attract the roaming user to select itself, it is difficult for the roaming user to notice the roaming operator in time among a plurality of selectable roaming operators, and the roaming user still can select one roaming operator at will. However, when the roaming user randomly selects a roaming operator from a plurality of selectable roaming operators, the roaming user may miss the service preference, the benefit cannot be guaranteed, and the user experience is poor.
In addition, roaming operators willing to provide preferential service are difficult to attract roaming users effectively, the competitiveness is poor, and the service development is limited.
In order to solve the above problem, the present invention provides a network handover method based on a blockchain network, wherein the blockchain network comprises at least one initial operator system, at least one roaming operator system and at least one user terminal. The initial operator system refers to an operator system to which a network to which the user terminal is currently connected belongs, that is, when the user terminal is at a home location, the initial operator system may be the home location operator system of the user terminal; in case the user terminal is at a roaming location, the initial operator system may also be the operator system of the roaming location to which the user terminal is currently connected.
Fig. 1 is a block chain network-based network handover method applied to a user terminal, which can be implemented in the form of an intelligent contract in a block chain network. As shown in fig. 1, the method comprises the steps of:
step S101, receiving a roaming network recommendation event which is sent by an initial operator system to which a currently connected network belongs and is signed by a roaming operator system in advance.
The roaming operator system is an operator system which is recommended to the user terminal by the initial operator system after the user terminal leaves a network coverage range corresponding to the initial operator system, is a roaming place where the user terminal is located, and can provide roaming network access service for the user terminal.
In one embodiment, the roaming network recommendation event is an event sent by the initial carrier system in the case that a roaming network recommendation transaction pre-signed by the initial carrier system and the roaming carrier system exists in the affiliated blockchain network.
The roaming network recommended transaction is a transaction which is made by an initial operator system and a roaming operator system in order to recommend the roaming operator system to a user corresponding to the user terminal. The roaming network recommended transaction record is in a block chain account book of a block chain network, and the roaming network recommended transaction comprises account information, a transaction settlement function and a user identifier corresponding to a user terminal.
It should be noted that, through the roaming network recommended transaction and roaming network recommended event, after the user terminal leaves the network coverage range corresponding to the initial operator system, the roaming operator system recommended by the initial operator system may be selected instead of randomly selecting the operator system in the roaming place, so as to ensure the user benefit and improve the user experience. The roaming operator system can also effectively attract roaming users, improve competitiveness and promote service development.
In some implementation scenarios, after receiving a roaming network recommendation event sent by an initial operator system to which a currently connected network belongs and signed by the roaming operator system in advance, a user terminal may obtain, from a blockchain network to which the initial operator system broadcasts, a roaming network recommendation transaction in the blockchain network based on its own user identifier. The roaming network recommends that the transaction have the signature of the original carrier system and the signature of the roaming carrier system. The user terminal can know that the user terminal recommends the transaction based on the roaming network, and if the user terminal is in the area covered by the roaming network of the roaming operator system, the user terminal selects the roaming network connected with the roaming operator system to obtain preferential resources.
In one embodiment, the roaming network recommendation event includes network information of the roaming operator system, wherein the network information uniquely corresponds to the roaming operator system. The network information includes preset network address information.
The data format of the roaming network recommended event may be: e { [ A { [ P2 ]，[address_range]Where E denotes a roaming network recommendation event. P 2 Refers to a roaming operator system, A P2 Refer to roaming operator system P 2 Address range represents network information of the roaming operator system, which includes preset network address information, such as 61.48.254.254 or 61.48.0.0/16.[ A ] P2 ]Is the input of the recommended event of the roaming network, and indicates that the preset network address information included in the address range is contained in the roaming operator system P 2 Among all of the self-owned network addresses. [ Address _ range]Is the output of the roaming network recommended event, which represents the network address marked by the preset network address information included in the address range, and is the input [ A ] from the roaming network recommended event P2 ]。
In some embodiments, to conserve operator system resources, the roaming network recommends entry of an event [ A P2 ]In the method, all the self-owned network addresses can be expressed by the address range without the need of the roaming operator system P 2 Each own network address is written.
Step S102, under the condition of being located in the preset roaming area, a network connection request is initiated to the roaming operator system based on the roaming network recommending event, so that the roaming operator system can provide network access service based on the network connection request.
The preset roaming area is a network coverage area corresponding to the roaming operator system.
In one embodiment, in the case of being located in a preset roaming area, the step of the user terminal initiating a network connection request to the roaming operator system based on a roaming network recommended event includes:
step one, acquiring a network identifier of a corresponding roaming operator system based on network information contained in a roaming network recommendation event.
Wherein the network identification of the roaming operator system is an identification code of a network belonging to the roaming operator system. The Network identifier includes a Mobile Country Code (MCC) and a Mobile Network Code (MNC). The roaming operator system has one and only one network identification.
It should be noted that the network information of different operator systems is different, and therefore, the roaming operator system corresponding to the network information can be identified based on the network information included in the roaming network recommendation event.
In some embodiments, the user terminal may pre-store a correspondence list of operator systems and network identifications. And after the user terminal identifies the corresponding roaming operator system based on the network information contained in the roaming network recommendation event, the user terminal inquires and obtains the network identifier of the roaming operator system based on the relation list.
In other embodiments, after the user terminal identifies the corresponding roaming operator system based on the network information included in the roaming network recommendation event, the network identifier of the roaming operator system may be obtained based on a correspondence between the operator system and the network identifier that are broadcast in the blockchain network in advance. The corresponding relationship between the operator system and the network identifier in the block chain network may be broadcast by each operator system in advance.
And step two, searching the roaming network, and identifying whether the searched roaming network carries the network identifier of the roaming operator system.
The roaming network carrying the network identifier of the roaming operator system is the roaming network belonging to the roaming operator system.
In some embodiments, the user terminal identifies whether the searched roaming network carries the network identifier of the roaming operator system. Under the condition that the searched roaming network does not carry the network identifier, the user terminal can arbitrarily select one searched roaming network for connection. And executing a third step in the embodiment when the searched roaming network is identified to carry the network identifier.
In other embodiments, the user terminal re-executes the step two when recognizing that the searched roaming network does not carry the network identifier, and may optionally select one searched roaming network for connection when the step two is executed more than a preset number of times (e.g., 5 times) and the searched roaming network still does not carry the network identifier. And executing a third step in the embodiment when the second step is executed for no more than the preset number of times and the searched roaming network is identified to carry the network identifier.
And step three, initiating a network connection request to the roaming network carrying the network identification.
After the user terminal initiates a network connection request to the roaming network carrying the network identifier, the roaming operator system corresponding to the roaming network provides network access service for the user terminal based on the network connection request, and the user terminal is connected to the roaming network belonging to the roaming operator system.
In one embodiment, after initiating a network connection request to the roaming operator system based on the recommended event in case of being located in the preset roaming area, the method further includes the following steps:
step one, under the condition of connecting to a roaming network belonging to a roaming operator system, signing a roaming network recommended event, for example, signing the roaming network recommended event by using a private key of a user terminal.
After the user terminal signs the roaming network recommended event, the roaming network recommended event has the signature of the initial operator system, the signature of the roaming operator system and the signature of the user terminal.
In some embodiments, to indicate that the user terminal is always connected to the roaming network belonging to the roaming operator system, the user terminal may sign the roaming network recommendation event at preset intervals, which may be 1 second, 1 minute, 10 minutes, 1 hour, 100 minutes, and the like, preferably 1 minute or 10 minutes. The user terminal stores roaming network recommended events at least carrying roaming operator system signatures, the user terminal adds own signatures to the roaming network recommended events and broadcasts the roaming network recommended events to the block chain network every other preset period, and the user terminal increases a roaming network recommended event at least carrying roaming operator system and user terminal signatures on the block chain network every time the user terminal broadcasts the roaming network recommended events.
Step two, broadcasting the signed roaming network recommendation event to the affiliated block chain network, so that the verification node in the block chain network records the roaming network recommendation event into a block chain account book of the block chain network under the condition that the verification node verifies that the roaming network recommendation event is broadcasted through the roaming network.
Specifically, the data format of the recommended event in the roaming network is E { [ A ] P2 ]，[address_range]In the case of the foregoing, after the user terminal broadcasts the signed roaming network recommended event to the affiliated blockchain network, the step of verifying, by a verification node in the blockchain network, that the roaming network recommended event is broadcasted by the roaming network includes:
a verification node in the blockchain network verifies whether the roaming network recommended event has a signature of the roaming operator network. And under the condition of verifying that the signature of the roaming operator network does not exist, the roaming network recommended event is considered as an invalid event, and a block chain account book of the block chain network is not included. And under the condition of verifying the signature of the roaming operator network, verifying whether the network address adopted by the user terminal for broadcasting the roaming network recommended event is within the network address range marked by the address range. If so, the roaming network recommended event is considered to be a roaming network broadcast of the roaming operator system, and the roaming network recommended event is recorded into a block chain account book of the block chain network; if not, the roaming network recommended event is not broadcast through the roaming network of the roaming operator system, and the roaming network recommended event is an invalid event and is not counted into a block chain account book of the block chain network.
In some embodiments, the blockchain network may include a plurality of verification nodes, and the step of verifying, by the verification node in the blockchain network, whether the network address used by the user terminal to broadcast the roaming network recommended event is within the network address range marked by the address _ range further includes:
if the verification node which is not less than the preset percentage (for example, 50%) verifies that the network address adopted by the user terminal for broadcasting the roaming network recommended event is within the address range marked by the address range, the roaming network recommended event is considered to be broadcasted through the roaming network, and the roaming network recommended event is recorded into a block chain account book of the block chain network; if the network address adopted by the user terminal for broadcasting the roaming network recommended event is verified to be within the address range marked by the address range by the verification node below a preset percentage (for example, 50%), the roaming network recommended event is considered not to be broadcasted through the roaming network, the roaming network recommended event is an invalid event, and a block chain account book of the block chain network is not counted.
In some embodiments, the user terminal is connected with the WIFI network while being connected with the roaming network of the roaming operator system. In order to avoid interference of the WIFI network on the roaming network recommended event after the broadcast signature, when the user terminal is connected to the roaming network belonging to the roaming operator system, the network adopted when the roaming network recommended event after the broadcast signature is set by default is the roaming network.
In some embodiments, in order to ensure the benefit of the user, the roaming operator system avoids charging the traffic generated by the roaming network recommendation event after the user terminal broadcasts the signature, so as to improve the user experience, attract the roaming user, and increase the competitiveness of the roaming operator system.
The embodiment of the invention provides a network switching method based on a block chain network, which comprises the following steps: receiving a roaming network recommendation event which is sent by an initial operator system to which a currently connected network belongs and is signed by a roaming operator system in advance, wherein the roaming network recommendation event is an event sent by the initial operator system under the condition that a signature is added to a roaming network recommendation transaction which is signed by the roaming operator system in advance and is broadcasted to a block chain network, the roaming network recommendation event comprises network information of the roaming operator system, and the roaming operator system can effectively attract roaming users through the roaming network recommendation transaction and the roaming network recommendation event, so that the competitiveness is improved. Under the condition that the user terminal is located in the preset roaming area, the user terminal does not need to randomly select an operator system, and can initiate a network connection request to the roaming operator system based on the roaming network recommendation event so that the roaming operator system can provide network access service based on the network connection request, the user benefit is guaranteed, and the user experience is improved.

In one embodiment, the data format of the roaming network recommended event generated by the initial operator system is: e { [ A { [ P2 ]，[ADDRESS_RANGE]And wherein ADDRESS _ RANGE represents the network information to be written.
In order to meet the requirements of different service scenes, in the roaming network recommendation transaction, the transaction settlement function can quote the roaming network recommendation event or not. For example, user resource accounting function f P1 And a collaborative resource settlement function f P2 The specific expressions of (2) may all be related to the roaming network recommendation event, only one of the specific expressions may exist and may not be related to the roaming network recommendation event, or both the specific expressions and the roaming network recommendation event may be related to the roaming network recommendation event.
In some embodiments, in order to guarantee the benefits of the operator system and maintain the safety of the operator system, after the roaming network recommended transaction and the roaming network recommended event are generated, the roaming network recommended transaction and the roaming network recommended event are signed, and the following step two is executed after the signature.
And step two, sending the roaming network recommended transaction and the roaming network recommended event to a roaming operator system so that the roaming operator system can write corresponding network information in the roaming network recommended event, wherein the network information comprises preset network address information.
In one embodiment, the roaming operator system P 2 After the corresponding network information is written in the roaming network recommendation event, the data format of the roaming network recommendation event is as follows: e { [ A { [ P2 ]，[address_range]I.e. P 2 And specifically assigning the ADDRESS _ RANGE in the roaming network recommended event E to modify the ADDRESS _ RANGE in the event E into ADDRESS _ RANGE. ADDRESS RANGE is a variable parameter and ADDRESS RANGE is one or more specific values. E.g., address range has a value of oneThe address field 61.48.0.0/16, or a specific address 61.48.254.254.
It should be noted that the roaming network recommended transaction includes account information and a transaction settlement function. In one embodiment, in a case where the transaction settlement function refers to the roaming network recommended event, since the roaming operator system writes corresponding network information in the roaming network recommended event after the initial operator system sends the roaming network recommended transaction and the roaming network recommended event to the roaming operator system, the roaming network recommended transaction referring to the roaming network recommended event needs to be re-signed by the initial operator system. The roaming operator system signs the roaming network recommended transaction, sends the self-signed roaming network recommended transaction to the initial operator system, adds a signature to the roaming network recommended transaction signed by the roaming operator system by the initial operator system, and broadcasts the roaming network recommended transaction signed by the initial operator system and the roaming operator system to the affiliated block chain network. The roaming network recommended transaction signed by the initial carrier system and the roaming carrier system has both the signature of the initial carrier system and the signature of the roaming carrier system.
In some embodiments, in order to maintain system security, after the initial operator system receives the roaming network recommended transaction signed by the roaming operator system, the initial operator system verifies whether the signature of the roaming operator system is correct, and if the signature of the roaming operator system is correct, the step of appending the signature to the roaming network recommended transaction signed by the roaming operator system is performed, and the roaming network recommended transaction signed by the initial operator system and the roaming operator system is broadcasted into the affiliated blockchain network.
In another embodiment, in a case that a transaction settlement function included in the roaming network recommended transaction does not refer to the roaming network recommended event, the initial operator system sends the roaming network recommended transaction and the roaming network recommended event to the roaming operator system, and after the roaming operator system writes corresponding network information in the roaming network recommended event, the roaming network recommended transaction does not need to be signed by the initial operator system again. The roaming operator system signs the roaming network recommended transaction and broadcasts the roaming network recommended transaction signed by the roaming operator system to the affiliated block chain network. The roaming network recommends that the transaction have both the signature of the original carrier system and the signature of the roaming carrier system.
It should be noted that the roaming network recommended transaction in the blockchain network has both the signature of the initial carrier system and the signature of the roaming carrier system, and therefore, the roaming network recommended transaction is established.
In one embodiment, in order to ensure the benefit and security of the operator system, after the initial operator system receives the roaming network recommended event sent by the roaming operator system and previously signed by the roaming operator system, the signature of the roaming network recommended event is verified, and after the signature of the roaming network recommended event is verified, the following step S202 is executed.
In order to meet the requirements of different service scenes, in the roaming network recommendation transaction, the transaction settlement function can quote the roaming network recommendation event or not. Since the roaming network recommended transaction has both the signature of the initial operator system and the signature of the roaming operator system, in order to save the resources of the operator system, under the condition that the transaction settlement function included in the roaming network recommended transaction refers to the roaming network recommended event, the initial operator system does not need to add a signature to the roaming network recommended event having the signature of the roaming operator system, and the following step S202 can be directly executed after the roaming network recommended transaction signed by the initial operator system is broadcasted to the blockchain network. However, in the case where the transaction settlement function included in the roaming network recommended transaction does not refer to the roaming network recommended event, the initial carrier system needs to add a signature to the roaming network recommended event that has already been signed by the roaming carrier system after broadcasting the roaming network recommended transaction signed by the initial carrier system to the blockchain network, and after adding a signature to the roaming network recommended event, the following step S202 is executed.
Step S202, under the condition that the roaming network recommended transaction which is pre-signed by the roaming operator system exists in the block chain network, sending a roaming network recommended event to the user terminal which is currently connected to the block chain network, so that the user terminal initiates a network connection request to the roaming operator system based on the roaming network recommended event under the condition that the user terminal is located in a preset roaming area, and the roaming operator system provides network access service to the user terminal based on the network connection request.
It should be noted that, by recommending an event through the roaming network, after the user terminal leaves the coverage area of the initial operator system, the roaming operator system recommended by the initial operator system can be selected instead of randomly selecting the operator system, thereby ensuring user benefits and improving user experience. And the roaming operator system can also effectively attract roaming users through the roaming network recommended transaction and the roaming network recommended event, thereby improving the competitiveness and promoting the development of services.
In one embodiment, in the case that the user terminal accesses a roaming network provided by a roaming operator system and a roaming network recommendation event sent by the user terminal through the roaming network exists in a blockchain account book of a blockchain network, the method further includes the following steps:
step one, based on a roaming network recommendation event and a transaction settlement function in a block chain account book, obtaining a preferential resource amount corresponding to a user terminal.
In one embodiment, the data format of the roaming network recommended event is: e { [ A { [ P2 ]，[address_range]And the data format of the recommended transaction of the roaming network is as follows: t { [ I ] P1 ,I P2 ]，[f P1 →U，f P2 →P 1 ]}. The step of obtaining the preferential resource amount corresponding to the user terminal based on the roaming network recommended event and the transaction settlement function in the block chain account book specifically includes: and calculating the preferential resource amount corresponding to the user terminal based on the user resource settlement function contained in the roaming network recommendation event and the transaction settlement function. For example:
example one, at the userResource settlement function f P1 In the case that the specific expression of (f) is related to the roaming network recommended event E (in the case that the transaction settlement function refers to the roaming network recommended event), the user resource settlement function f P1 The specific expression of (a) may be:
(1)f P1 (E) = n (count (E)/m), which represents that for each m roaming network recommended events E stored in the blockchain account book, the user U can obtain the initial operator system P 1 N units of resources. Wherein, count (E) represents the count of the roaming network recommended events of the user U in the blockchain account book, and n and m are both weight parameters. For example, n may be 0.01, m may be 1000, then f P1 (E) = n (count (E)/m) represents that a user U can obtain an initial operator system P for every 1000 roaming network recommended events E stored in the blockchain account book 1 0.01 units of resources, e.g., 0.01 yuan.
(2)f P1 (E) And n (count-up (E)/m), wherein count-up (E) represents rounding up the count of the roaming network recommended events of the user U in the blockchain account, that is, less than m is counted by m.
(3)f P1 (E) And n (count-down (E)/m), wherein count-up (E) represents that the count of the roaming network recommended events of the user U in the blockchain account is rounded down, that is, less than m is calculated by 0.
(4)f P1 (E) = P (time (E)/q), which represents the user U per roaming operator system P 2 The roaming network residence time q, the user U can obtain the initial operator system P 1 P units of resources. Wherein time (E) indicates that the user U is in the roaming operator system P 2 P and q are weighting parameters, e.g. p may be 0.01, q may be 1000, then f P1 (E) = P (time (E)/q) represents the user U per roaming operator system P 2 The roaming network of (1) resides for 1000 minutes, and the user U can obtain the initial operator system P 1 0.01 units of resources, e.g., 0.01 yuan.
In some embodiments, the user terminal signs the roaming network recommended event every preset period and broadcasts the signed roaming network recommended event to the affiliated block chain network, so that the verification node in the block chain network records the roaming network recommended event into the block chain book of the block chain network when verifying that the roaming network recommended event is broadcast through the roaming network. The preset period is the broadcast time interval of two adjacent roaming network recommended events. Therefore, the roaming network recommended events can be counted through the roaming network recommended events recorded in the block chain account book, so that count (E) in the formula is obtained, and then the comparison result of the count (E) and m determines count-up (E) and count-down (E).
In some embodiments, any node in the blockchain network (e.g., the original carrier system or the roaming carrier system) is roaming the user U at the roaming carrier system P 2 The method for counting the residence time of the roaming network comprises the following steps: and acquiring each residence time period of the user U in the roaming network, and summing the residence time periods to obtain the residence time of the roaming network.
Specifically, a time interval between two roaming network recommended events E of a user U who continuously stores a block chain account book is obtained, and if the time interval does not exceed a preset time interval (for example, 2 minutes), it is determined that the two roaming network recommended events E are in the same residence time period; if the time interval exceeds a preset time interval (for example, 2 minutes), it is determined that, in the two consecutive roaming network recommended events E, the former roaming network recommended event E is the end of the last residence time period, and the latter roaming network recommended event E is the start of the next residence time period. For example, in the case where 1 roaming network recommended event E of user U is stored in the blockchain ledger at time 00, 01, 00, 02, 00, 03, 00.
Example two, settlement of function f at user resources P1 Is independent of the roaming network recommendation event EIn the case (in the case where the transaction settlement function does not refer to the roaming network recommended event), the user resource settlement function f P1 The specific expression of (a) may be: f. of P1 (t) = f, which means that in the period defined by t, as long as there is a roaming network recommended event sent by the ue through the roaming network in the block chain account book, the user U can obtain the initial operator system P 1 The unit of f is the resource, wherein t is a preset resource settlement period, f is a preset settlement preferential resource amount, and both t and f are constants. E.g., t =15, f =1, then f P2 (t) = f indicates that in each 15 days, as long as a roaming network recommendation event sent by the user terminal through the roaming network is stored in the block chain account book, the user U corresponding to the user terminal can obtain the initial operator system P 1 For example, a 1-dollar rate reward.
And step two, sending the preferential resources corresponding to the amount of the preferential resources to a resource account of the user terminal.
In some embodiments, the initial operator system may reduce the monthly bill of the user terminal from the preferential resource corresponding to the amount of the preferential resource, for example, when the bill is issued, the bill amount is reduced by the amount of the corresponding amount.

And then, sending the roaming network recommendation event to a user terminal currently connected to the own network, so that the user terminal does not need to randomly select an operator system under the condition that the user terminal is located in a preset roaming area, but initiates a network connection request to the roaming operator system based on the roaming network recommendation event, and the roaming operator system provides a network access service to the user terminal based on the network connection request, so that the user benefit is guaranteed, and the user experience is improved.

ADDRESS RANGE is a variable parameter and ADDRESS RANGE is one or more specific values. For example, the address range has a value of 61.48.0.0/16 or a specific address 61.48.254.254.
In one embodiment, in the case that the address allocated by the roaming operator system to the user terminal is a private network address (for example, any one of 10.0.0.0/24), the value of the preset network address information included in the network information written by the roaming operator system is the address of the port of the egress device (for example, a router or a switch) from the roaming network to the blockchain system.
And step three, signing the roaming network recommended transaction and the roaming network recommended event written with the network information.
In one embodiment, the roaming network recommended event written with the network information is signed by using a private key of the roaming operator system, and the step S301 is executed after signing.

Wherein, the count (E) represents the count of the roaming network recommended events of the user U in the blockchain account book, and r and m are both weight parameters. For example, r may be 0.02, m may be 1000, then f P2 (E) = r (count (E)/m) represents 1000 roaming network recommended events E per user U stored in the blockchain account book, and the initial operator system P 1 Roaming operator system P can be obtained 2 0.02 units of resources, e.g., 0.02 yuan.
(2)f P2 (E) N (= n) (count-up (E)/m), where count-up (E) represents rounding up the count of the roaming network recommended event for the user U in the blockchain ledger, i.e., less than m counts by m.

In some implementation scenarios, because the coverage of the initial operator system is limited, for example, in many areas in europe, the geographic range of the country is small, and many operators exist in each country at the same time, in the case of one large operator system simultaneously covering the initial operator system and the roaming operator system in the embodiment of the present invention, both the initial operator system and the roaming operator system face a large competitive pressure. By the network switching method based on the block chain network, provided by the embodiment of the invention, the initial operator system and the roaming operator system achieve the roaming network recommended transaction in advance, and can cope with the competition of the large operator system together. And the initial operator system sends the roaming network recommendation event to the user terminal corresponding to the user belonging to the initial operator system. The roaming operator system can effectively attract roaming users based on the roaming network recommended transaction and the roaming network recommended event, improve competitiveness and promote business development. When the user terminal corresponding to the user belonging to the initial operator system leaves the coverage area of the initial operator system and enters the area covered by the roaming operator system, the roaming network of the roaming operator system is preferentially selected to be connected based on the roaming network recommending event, so that the user benefit can be guaranteed, the user experience is improved, and the win-win situation is realized with the initial operator system and the roaming operator system.
The description of the user terminal, the initial operator system, the roaming operator system, and the verification node is detailed in the above embodiments, and will not be described herein again.
It should be noted that, in the network switching system based on the blockchain network, the initial operator system and the roaming operator system are not specific to a certain operator system, but only identify the identity of the operator system included in the network switching system based on the blockchain network under different conditions, and the operator system included in the network switching system based on the blockchain network may implement a function as both the initial operator system and the roaming operator system.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
