[0003] However, this will cause the terminal to need to store multiple sets of software, occupying a large amount of the terminal's storage space, reducing the data processing speed of the terminal, and the terminal also needs to maintain multiple software, which will also reduce the operation and maintenance efficiency.

[0022] Currently, for different types of communication subnets, in order for a terminal to adapt to a wider range of service support, there are usually multiple different software. For example, based on the service requirements of multiple sub-operators under a certain main operator, software corresponding to each sub-operator is stored respectively, so that when the terminal supports the service processing of a certain sub-operator, one of the software can be selected to run.

[0023] However, this will cause the terminal to need to store multiple sets of software, occupying a large amount of the terminal's storage space, reducing the data processing speed of the terminal, and the terminal also needs to maintain multiple software, which will also reduce the operation and maintenance efficiency.

[0024] To solve the above problems, the present disclosure provides a communication method, a terminal, a computer-readable medium and a computer program product.

[0025] In a first aspect, an embodiment of the present disclosure provides a communication method.

[0026] Figure 1Schematic flowchart of a communication method provided by an embodiment of the present disclosure. This communication method is applied to a terminal, and the terminal stores a basic version, which includes a common module and multiple alternative branch modules, and each alternative branch module corresponds to a communication subnet.

[0027] Among them, the common module is a module for supporting the basic operation of the terminal, or common code in the software for supporting the operation of the terminal.

[0028] In some embodiments, the terminal provided by the present disclosure can be a terminal used in any of the following application scenarios: Digital Subscriber Line (DSL) communication scenario, Fiber to the Room (FTTR) communication scenario, Fiber To The Home (FTTH) communication scenario, and Gigabit-Capable Passive Optical Network (GPON) communication scenario.

[0029] As Figure 1 shown, this communication method includes but is not limited to the following steps.

[0030] Step S101, determine that the current communication subnet is the target communication subnet.

[0031] Among them, the current communication subnet is the communication subnet that the terminal has currently entered. If the communication subnet where the terminal was previously located is not the target communication subnet, the terminal needs to adjust the software it runs at this time to support the communication services carried out by the terminal in the target communication subnet.

[0032] For example, the software currently running on the terminal is software that supports the first communication subnet. When the terminal enters the second communication subnet (i.e., the target communication subnet), the terminal needs to switch the software that supports the first communication subnet to software that supports the target communication subnet.

[0033] Step S102, select a target branch module corresponding to the target communication subnet from multiple alternative branch modules.

[0034] Among them, the target branch module is a module that can support the terminal to communicate in the target communication subnet.

[0035] Each alternative branch module corresponds to a communication subnet. By combining any alternative branch module with the common module, the obtained version can support the terminal to communicate in any one of multiple communication subnets.

[0036] In some embodiments, each alternative branch module can be implemented in the form of different configuration files or in the form of code branches.

[0037] Step S103, load the target branch module.

[0038] Among them, by selecting and loading the target branch module in the base version, the obtained version can support the communication of the terminal in the target communication subnet.

[0039] In the communication method of the embodiments of the present disclosure, the base version is stored in the terminal in the form of a common module and multiple alternative branch modules. Compared with the prior art in which multiple different software are stored on the terminal side, the storage space of the terminal can be saved; after determining that the current communication subnet is the target communication subnet, the terminal selects the target branch module corresponding to the target communication subnet from multiple alternative branch modules and loads the target branch module, so that the terminal can realize communication in the target communication subnet based on the base version loaded with the target branch module. Compared with the prior art, the terminal does not need to maintain multiple software, thereby improving the operation and maintenance efficiency.

[0040] In some embodiments, before performing the determination in step S101 that the current communication subnet is the target communication subnet, the method further includes: loading the common module.

[0041] Among them, the common module is a module for supporting the basic operation of the terminal, or the common code in the software for supporting the operation of the terminal. For example, the common module is a basic logic processing module such as system initialization and power-on processing, or the common code in the software versions corresponding to each alternative communication subnet supported by the terminal.

[0042] To ensure the normal operation of the terminal, as a way of the embodiments of the present disclosure, the terminal needs to first load the common module and then load the target branch module to realize the communication support for the target communication subnet, so as to realize the version formed by the base version based on the common module and the target branch module, and support the terminal to communicate in the target communication subnet.

[0043] In some embodiments, the determination in step S101 that the current communication subnet is the target communication subnet can be implemented in the following manner: in response to the received configuration message, obtain the service identifier carried in the configuration message; according to the service identifier, determine that the current communication subnet is the target communication subnet.

[0044] Among them, the service identifier is used to identify the corresponding communication subnet.

[0045] When the network-side device configures the terminal, one configuration only corresponds to opening a service channel corresponding to one communication subnet. In other words, only one service identifier corresponding to one communication subnet is carried in one configuration message. When the service identifier carried in the received configuration message is the same as the service identifier corresponding to the target communication subnet, it is determined that the current communication subnet is the target communication subnet.

[0046] As a way of an embodiment of the present disclosure, by means of the network-side device sending a configuration message to the terminal, the terminal can clearly know that the current communication network it is in is the target communication subnet, so as to facilitate the terminal to select the target branch module corresponding to the target communication subnet from multiple alternative branch modules; thereby, based on the version determined by the target branch module and the common module, support the terminal to communicate in the target communication subnet.

[0047] In some embodiments, the configuration message includes an idle field defined by a preset communication protocol, and the service identifier is stored in the idle field.

[0048] Among them, the preset communication protocol includes the communication protocol for short-range communication between the network-side device and the terminal. For example, if the short-range communication supported between the network-side device and the terminal is mobile hotspot (WiFi) communication, then the preset communication protocol is the WiFi communication protocol (such as, 802.11 ax standard protocol, etc.). If the short-range communication supported between the network-side device and the terminal is Bluetooth communication, then the preset communication protocol is the Bluetooth communication protocol.

[0049] The service identifier stored in the idle field can be any one of the following fields: the option 43 field in the Dynamic Host Configuration Protocol (DHCP), the option 15 field in the DHCP, the option 60 field in the DHCP, and the custom field in the Point-to-Point Protocol Over Ethernet (PPPoE).

[0050] By storing the service identifier in the idle field defined by the above preset communication protocol, there is no need to reconstruct the communication message again. The service identifier can be carried only through the original preset communication protocol, reducing the number of communication messages. At the same time, it can also enable the terminal to quickly know the service identifier corresponding to the target communication subnet it needs to support, which is beneficial for the terminal to quickly switch versions, support the normal communication of the terminal in the target communication subnet, and improve the communication efficiency.

[0051] In some embodiments, determining that the current communication subnet is the target communication subnet according to the service identifier includes: in response to the service identifier including the first type of target virtual local area network channel identifier, determining that the current communication subnet corresponding to the first type of target virtual local area network channel identifier is the target communication subnet.

[0052] Among them, each first - type target virtual local area network (VLAN) channel identifier corresponds to an alternative communication subnet. The first - type target VLAN channel identifier is the identifier of the terminal configured by the network - side device in the target VLAN channel.

[0053] By querying the pre - planned correspondence table between VLAN channel identifiers and each alternative communication subnet, it can be known that the first - type target VLAN channel identifier carried in the current configuration message corresponds to only one alternative communication subnet. Then, only by extracting this first - type target VLAN channel identifier can the service identifier be obtained, and then based on this first - type target VLAN channel identifier, the corresponding communication subnet is determined as the target communication subnet.

[0054] As a way of the embodiment of the present disclosure, by receiving a configuration message and confirming that the first - type target VLAN channel identifier carried in the configuration message corresponds to only one alternative communication subnet, the corresponding communication subnet can be directly determined as the target communication subnet based on this first - type target VLAN channel identifier, improving the recognition speed of the target communication subnet.

[0055] In some embodiments, determining the current communication subnet as the target communication subnet according to the service identifier includes: in response to the service identifier including a second - type target VLAN channel identifier and the device parameters of the alternative communication subnet, determining the target communication subnet according to the second - type target VLAN channel identifier and the device parameters of the alternative communication subnet.

[0056] Among them, each second - type target VLAN channel identifier corresponds to at least two alternative communication subnets, and the combination of each second - type target VLAN channel identifier and the device parameters of each alternative communication subnet corresponds to an alternative communication subnet.

[0057] By querying the pre - planned correspondence table between VLAN channel identifiers and each alternative communication subnet, it can be known that the second - type target VLAN channel identifier carried in the current configuration message corresponds to at least two alternative communication subnets, and the device parameters of each alternative communication subnet are different. Therefore, the second - type target VLAN channel identifier and the device parameters of the alternative communication subnet can be jointly used as the service identifier, and then based on this service identifier, the corresponding target communication subnet is determined to accelerate the recognition speed of the target communication subnet.

[0058] For example, by querying the correspondence table between the pre-planned VLAN channel identifiers and each alternative communication subnet, it can be determined that the second type of target VLAN channel identifier is 300, which can correspond to alternative communication subnet C or alternative communication subnet D; when the second type of target virtual local area network channel identifier carried in the configuration message received by the terminal is 300, and the device parameter of the alternative communication subnet carried is the network address information of alternative communication subnet C, the target communication subnet can be determined to be alternative communication subnet C.

[0059] Using the above method to determine the service identifier and determining the target communication subnet based on this service identifier can more accurately confirm different alternative communication subnets, so as to determine which specific alternative communication subnet the terminal is currently in based on a more accurate service identifier, improving the accuracy of determining the target communication subnet.

[0060] In some embodiments, the device parameters of the alternative communication subnet include at least one of the following: the network address identifier of the network-side device, the type information of the terminal, and the mask information of the communication subnet where the terminal is located.

[0061] In some embodiments, each alternative branch module includes alternative service parameters, and / or alternative service processing logic.

[0062] Among them, the alternative service parameters are parameters representing the business data processing in the corresponding alternative communication subnet in the alternative branch module; the alternative service processing logic is the logic for the alternative branch module to process the business data in the alternative communication subnet.

[0063] For example, the alternative service parameters include parameters such as the subnet identifier of the alternative communication subnet and the service types that the alternative communication subnet can support, and these alternative service parameters can be updated in the form of a configuration file.

[0064] For another example, the alternative service processing logic can be implemented in the form of alternative code branches. When it is determined that a certain alternative branch module needs to be used to support the business data processing in its corresponding alternative communication subnet, the alternative code branch corresponding to the identifier of the alternative communication subnet can be selected in the basic version to implement the processing of the business data of the alternative communication subnet.

[0065] By characterizing the processing method of service data in an alternative communication subnet based on alternative service parameters and / or alternative service processing logics, the service data in the alternative communication subnet can be processed more precisely, thereby improving the processing accuracy of service data. At the same time, the terminal does not need to store specific software corresponding to the alternative communication subnet anymore. It only needs to screen and load alternative branch modules based on the basic version to obtain a version that can support the processing of service data in the alternative communication subnet, thereby reducing the occupied proportion of the storage space of the terminal and improving the processing speed of the terminal for service data.

[0066] In some embodiments, before loading the target branch module in step S103, the method further includes: unloading the historical branch module.

[0067] The historical branch module is the branch module used at the previous moment when entering the current communication subnet.

[0068] For example, it is set that the communication subnet where the terminal is located at the first moment is the first communication subnet, and the communication subnet where the terminal is located at the second moment is the second communication subnet, and the first moment is the previous moment of the second moment; then when the terminal switches from the first communication subnet to the second communication subnet, it needs to unload the historical branch module corresponding to the first communication subnet in the version used at the first moment, and then load the target branch module corresponding to the second communication subnet, so as to obtain a new version that can support the service processing of the terminal in the second communication subnet (i.e., the target communication subnet).

[0069] It should be noted that when the terminal is in the factory settings, a default branch module is default set in the stored basic version. The default version generated by the default branch module and the common module can support the terminal to process corresponding service data in the communication subnet corresponding to the default branch module.

[0070] When the terminal first enters an actual communication subnet (such as the first communication subnet) for communication, its corresponding default branch module can also be regarded as a historical branch module; at this time, the terminal needs to unload the default branch module and load the target branch module corresponding to the first communication subnet, so that the loaded version corresponds to the first communication subnet and supports the terminal to process corresponding service data in the first communication subnet.

[0071] By adopting the above-mentioned offloading historical branch module and loading the target branch module, the replacement of the software of different communication subnets on the terminal is realized. Compared with the method in the prior art where the terminal needs to store the software codes and versions corresponding to multiple alternative communication subnets, it can obtain the version corresponding to the target communication subnet more quickly and conveniently, and support the terminal to process the corresponding service data in the target communication subnet. This not only reduces the occupation ratio of the storage space of the terminal, but also improves the processing efficiency of the service data in the target communication subnet by the terminal.

[0072] In some embodiments, the terminal in the present disclosure can be any one of the following devices: a router, a gateway device, and an ONU in an optical network.

[0073] For example, the terminal is an optical network unit ONU in an optical network; the network address identifier of the network-side device is the network address identifier of the target optical line terminal OLT connected to the ONU.

[0074] For example, Figure 2 It is a block diagram of the composition of a communication system provided by an embodiment of the present disclosure. As Figure 2 shown, the communication system includes an optically connected optical line terminal (Optical Line Terminal, OLT) 201 and an optical network unit (Optical Network Unit, ONU) 202.

[0075] Among them, the ONU 202 stores a basic version to support the ONU to communicate in the communication subnet corresponding to the target OLT (such as, OLT 201). The basic version includes a common module and multiple alternative branch modules, and each alternative branch module corresponds to a communication subnet.

[0076] Figure 3 It is another block diagram of the composition of a communication system provided by an embodiment of the present disclosure. As Figure 3 shown, a broadband remote access server (Broadband Remote Access Server, BRAS) 310 is connected to an optical line terminal OLT 320, and the optical line terminal OLT 320 is connected to an optical network unit ONU 330.

[0077] Among them, the ONU 330 includes: an ONU management and control interface (ONU Management and Control Interface, OMCI) module 331, a network connection module 332, and multiple service sub-modules (such as, a first service sub-module 3331, a second service sub-module 3332,..., a kth service sub-module 333k, etc., where k is an integer greater than or equal to 1).

[0078] The BRAS 310 is used to allocate corresponding Internet Protocol (IP) addresses to Wide Area Network (WAN) connections corresponding to multiple main operators, so as to distinguish different main operators using different IP addresses.

[0079] The OLT 320 is used to configure the VLAN channel of the WAN connection to which the ONU 330 belongs through OMCI messages.

[0080] Among them, the OMCI message can be a configuration message, and the configuration message carries the target virtual local area network identifier of the target main operator corresponding to the OLT 320, and / or the network address identifier of the network side device.

[0081] In some embodiments, the BRAS 310 may use the value of DHCP option 43 (or, the value of DHCP option 15, or, the value of DHCP option 60, or, the value corresponding to the custom field in DHCP, or, the value corresponding to the custom field in PPOE, etc.) to represent the network address identifier of the network side device, so as to distinguish the identifier of the target sub-operator under the target main operator.

[0082] The OMCI module 331 is used to receive and parse the configuration message sent by the OLT 320 to obtain the target virtual local area network channel identifier configured by the OLT 320; and send the target virtual local area network channel identifier to the network connection module 332, so that the network connection module 332 can select the service sub-module corresponding to the target virtual local area network channel identifier from multiple service sub-modules according to the target virtual local area network channel identifier for service data processing.

[0083] The network connection module 332 is used to select a target service sub-module (such as the second service sub-module 3332) from multiple service sub-modules according to the received target virtual local area network channel identifier and / or the network address identifier of the network side device, and specify the target service sub-module to execute the target service of the target sub-operator under the target main operator.

[0084] The target service sub-module in the ONU 330 processes the service data in the corresponding target communication subnet (that is, the communication subnet corresponding to the target sub-operator) based on its corresponding target virtual local area network channel identifier.

[0085] In some embodiments, when the target service sub-module is selected as the second service sub-module 3332, based on the identifier of the target sub-operator corresponding to the second service sub-module 3332, on the basis of the common module in the basic version, a target branch module corresponding to the identifier of the target sub-operator is loaded to obtain a version for processing the service data of the target sub-operator, so that each module in the ONU 330 can, based on the service processing logic of this version, cooperate with the second service sub-module 3332 to execute the corresponding processing of the service data.

[0086] By storing the basic version in an ONU in the form of a common module and multiple alternative branch modules, compared with the prior art of storing multiple different software codes and versions on the terminal side, it is possible to save the storage space of the ONU; moreover, it can achieve high sharing of software, reduce the workload of software development and maintenance, and improve the scalability and flexibility of the terminal.

[0087] In some embodiments, each sub-operator is an operator that leases the basic network resources provided by the main operator, so that each sub-operator can perform corresponding communication service processing based on the basic network resources provided by the main operator. For example, a certain sub-operator sets different communication packages to meet the service usage requirements of different terminal users.

[0088] In some embodiments, the main operator is an operator that can provide comprehensive network services (such as, including broadband services, mobile network access services, etc.) for each sub-operator.

[0089] In some embodiments, the number of service sub-modules in the ONU 330 is 4, corresponding to supporting the service processing of 4 different sub-operators (such as, sub-operator A, sub-operator B, sub-operator C, sub-operator D).

[0090] Among them, in the process of network planning, the BRAS 310 will set that sub-operator A corresponds to use the preset virtual local area network (VLAN) channel identifier of 100, sub-operator B corresponds to use the preset VLAN channel identifier of 200, sub-operators C and D correspond to use the preset VLAN channel identifier of 300, the network address of the OLT corresponding to sub-operator C is C, and the network address of the OLT corresponding to sub-operator D is D.

[0091] In some embodiments, the preset VLAN channel is the communication channel corresponding to each virtual local area network (VLAN) included in the wide area network (WAN).

[0092] The network addresses of different OLTs are characterized by the value of DHCP option 43 (or the value of DHCP option 15, or the value of DHCP option 60, or the value corresponding to the custom field in DHCP, or the value corresponding to the custom field in PPOE, etc.) carried in the configuration message.

[0093] Figure 4 It is a schematic flowchart of another communication method provided by an embodiment of the present disclosure. As Figure 4 shown, the communication method includes but is not limited to the following steps.

[0094] Step S401, when the ONU 330 requests to access the OLT 320, the OLT 320 configures a corresponding network channel for the ONU 330 according to the attribute information of the ONU 330.

[0095] Among them, the attribute information of the ONU 330 includes the type information of the ONU, the type information of the sub - operators supported by the ONU, etc. When the OLT 320 configures the network channel for the ONU 330, each configuration only corresponds to opening the service channel corresponding to one communication subnet.

[0096] It should be noted that when the ONU 330 is powered on and initialized, it needs to load the common module in the basic version and the default branch module with default configuration to realize the software support for the ONU 330.

[0097] Among them, the default branch module is a module used to support the ONU 330 to communicate in its default communication subnet.

[0098] Step S402, the ONU 330 responds to the configuration message sent by the OLT 320, parses the configuration message, and obtains the service identifier carried in the configuration message.

[0099] Among them, the service identifier characterizes which alternative communication subnet the ONU 330 is currently in, so as to determine which alternative branch module in the basic version the ONU 330 specifically uses to support the ONU 330 to communicate in its current communication subnet.

[0100] In some embodiments, the service identifier includes the first - type target virtual local area network channel identifier, and each first - type target virtual local area network channel identifier corresponds to an alternative communication subnet.

[0101] In some embodiments, the service identifier includes a second type of target virtual local area network (VLAN) channel identifier and device parameters of an alternative communication subnet; wherein, each second type of target VLAN channel identifier corresponds to at least two alternative communication subnets, and a combination of each second type of target VLAN channel identifier and device parameters of each alternative communication subnet corresponds to an alternative communication subnet.

[0102] In some embodiments, the OMCI module 331 in the ONU 330 is configured to receive a configuration message sent by the OLT 320, parse the configuration message to obtain the service identifier carried in the configuration message, and then send the service identifier to the network connection module 332, so that the network connection module 332 selects a corresponding service sub-module according to the service identifier to process corresponding service data.

[0103] Wherein, each service sub-module in the ONU 330 corresponds to an alternative branch module in the base version.

[0104] Step S403, the ONU 330 determines whether the target VLAN channel identifier in the service identifier is 100.

[0105] If it is determined that the target VLAN channel identifier in the service identifier is 100, step S404 is executed; if it is determined that the target VLAN channel identifier in the service identifier is not 100, step S405 is executed.

[0106] Step S404, the ONU 330 determines that the current communication subnet is the target communication subnet corresponding to the VLAN channel identifier of 100, and selects a target branch module corresponding to the target communication subnet from multiple alternative branch modules (such as, Figure 3 multiple service sub-modules in) in the base version; unloads the default branch module, and loads the target branch module to obtain a version corresponding to the target branch module.

[0107] In some embodiments, the default branch module may also be a historical branch module, which is used to represent the branch module used by the ONU 330 before obtaining the configuration message; the historical branch module is used to support the ONU 330 to communicate in the communication subnet corresponding to the historical branch module.

[0108] Step S405, the ONU 330 determines whether the target VLAN channel identifier in the service identifier is 200.

[0109] If it is determined that the target VLAN channel identifier in the service identifier is 200, step S406 is executed; if it is determined that the target VLAN channel identifier in the service identifier is not 200, step S407 is executed.

[0110] Step S406: The ONU 330 determines that the current communication subnet is the target communication subnet corresponding to the virtual local area network (VLAN) channel identifier 200, and selects the target branch module corresponding to the target communication subnet from multiple alternative branch modules in the base version (such as, Figure 3 multiple service sub-modules therein); unloads the default branch module and loads the target branch module to obtain the version corresponding to the target branch module.

[0111] Step S407: The ONU 330 determines whether the target VLAN channel identifier in the service identifier is 300.

[0112] If it is determined that the target VLAN channel identifier in the service identifier is 300, step S408 is executed; if it is determined that the target VLAN channel identifier in the service identifier is not 300, the process ends.

[0113] Step S408: The ONU 330 determines whether the network address of the OLT in the service identifier is C.

[0114] If it is determined that the network address of the OLT in the service identifier is C, step S409 is executed; if it is determined that the network address of the OLT in the service identifier is not C, step S410 is executed.

[0115] Step S409: The ONU 330 determines that the current communication subnet is the target communication subnet, and the service identifier corresponding to the target communication subnet includes a VLAN channel identifier of 300 and an OLT network address of C; selects the target branch module corresponding to the target communication subnet from multiple alternative branch modules in the base version (such as, Figure 3 multiple service sub-modules therein); unloads the default branch module and loads the target branch module to obtain the version corresponding to the target branch module.

[0116] Step S410: The ONU 330 determines whether the network address of the OLT in the service identifier is D.

[0117] If it is determined that the network address of the OLT in the service identifier is D, step S411 is executed; if it is determined that the network address of the OLT in the service identifier is not D, the process ends.

[0118] Step S411: The ONU 330 determines that the current communication subnet is the target communication subnet, and the service identifier corresponding to the target communication subnet includes a VLAN channel identifier of 300 and an OLT network address of D; selects the target branch module corresponding to the target communication subnet from multiple alternative branch modules in the base version (such as, Figure 3 multiple service sub-modules therein); unloads the default branch module and loads the target branch module to obtain the version corresponding to the target branch module.

[0119] Step S412, the ONU 330 runs based on the version corresponding to the target branch module.

[0120] In this embodiment, by storing the base version in the terminal in the form of a common module and multiple alternative branch modules, compared with the prior art of storing multiple different software on the terminal side, the terminal in this embodiment does not need to store the software corresponding to multiple communication subnets separately, but only distinguishes different communication subnets in the form of alternative branch modules, thereby saving the storage space of the terminal, realizing the highly shared code in the software, and greatly reducing the development workload. Further, when it is necessary to maintain or update the base version according to actual usage requirements, only the respective alternative branch modules need to be selected, and no operation needs to be performed on the common module, reducing the complexity and risk of maintenance.

[0121] Moreover, when a new communication subnet needs to be supported by the terminal, the terminal only needs to add the backup branch module corresponding to the newly added communication subnet (for example, implemented by adding based on a configuration file, etc.), thereby enhancing the compatibility and scalability of the terminal.
