[0020] For a clearer understanding of the purpose, technical examples and advantages of the present invention, embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present invention may be combined with each other in any combination, provided there is no conflict.

[0021] The steps shown in the flowcharts of the accompanying drawings may be performed on a computer system by a program consisting of a set of commands executed in a strictly defined sequence. In addition, although the flowcharts show a logical sequence, in some cases the steps shown or described may be performed in a different sequence from that shown in the present invention.

[0022] Embodiments of the present invention provide a service configuration method as shown in Figure 1, including.

[0023] Step 101: Sending a request for service configuration information from the ONU to the OLT based on the pre-purchased service information.

[0024] The service configuration information of one of the illustrative examples is information corresponding to the complete set of functions necessary for the normal operation of the subsequent system.

[0025] In this illustrative example, after connecting the ONU to the OLT system, first, system access authentication is performed, including discovery, authentication, and registration. The GPON system must meet the ITU-T G.984.3 Gigabit Passive Optical Network link aggregation and data transmission layer specifications, the Next Generation Passive Optical Network (NG-PON) must meet the link aggregation and data transmission layer specifications of 10 - Gigabit ITU-T G.987.3 passive optical network, and the Ethernet passive optical network (EPON) system must comply with the IEEE 802.3 Ethernet protocol, details will not be repeated here.

[0026] Step 102: configuring the service at the ONU based on the pre-purchased service information.

[0027] A request for service configuration information based on the pre-acquired service information performed by the ONU based on the pre-acquired service information of another illustrative example comprises the steps of:

[0028] First, the ONU generates a service configuration information request based on the previously acquired service information and the communication protocol message specified in the field extension.

[0029] The communication protocol of another illustrative example is the communication protocol between the ONU and the OLT.

[0030] In this illustrative example, the ONU extracts information to be configured at the OLT and reported to the OLT from the pre-purchased service information to generate a request for service configuration information to be sent to the OLT; wherein the request for service configuration information contains all OLT-ONU configuration parameters necessary for downloading and forwarding the preset service, such as parameters of the media used to download and transmit the service (Transmission Container, T-CONT) in the direction of the GPON uplink, identifier distributions (Alloc IDentifier, Alloc-ID), GPON encapsulation mode port ID (G-PON Encapsulation Mode port Id), quality of service (Quality of Service, QoS, parameters of a virtual local area network (VLAN) of a gigabit passive optical network (Gigabit-CapablePassive Optical Network, GPON), Ethernet type; EPON system information such as logical link identifier (LLID), QoS, VLAN, and Ethernet type.

[0031] The ONU then sends a request for service configuration information to the OLT.

[0032] After receiving a request for service configuration information from the ONU, the OLT, in yet another illustrative example, also needs to perform the following operations:

[0033] Based on the service configuration information request, the OLT configures the VLAN information that is connected to the PON port on the OLT terminal, the VLAN information that is connected to the Ethernet port on the WAN terminal.

[0034] A request for service configuration information sent by the ONU to the OLT based on the pre-purchased service information of yet another illustrative example comprises:

[0035] Preferably, the ONU generates a request for service configuration information based on pre-acquired service information and based on managed entities defined in the scope extension of this standard.

[0036] The framework of the standard for this illustrative example is those followed by the system where the ONU and OLT are located.

[0037] Additionally, the ONU sends a request for service configuration information to the OLT.

[0038] According to another illustrative example, when the ONU and the OLT are located in a GPON gigabit passive optical network system, the communication protocol message is an optical network unit management and control interface (ONU Management and Control Interface, OMCI) message. Generating a service configuration information request at the ONU based on the previously acquired service information and using the communication protocol message defined in the field extension comprises the following steps, in which:

[0039] First, the ONU determines the parameters corresponding to the resources to be configured by the OLT for the ONU or the OLT itself based on the pre-purchased service information.

[0040] Then, the specified ONU terminal creates at least one OMCI profile containing the received parameters.

[0041] Finally, the ONU loads the received OMCI profile into the OMCI message and sets the MSB of the message type field in the OMCI message to a value indicating that the OMCI message sent to the OLT was used to request a service configuration, to be used as information about a service configuration request; wherein the MSB of the message type field in the OMCI message is pre-expanded as a value indicating whether the OMCI message sent to the OLT was used to request the service configuration.

[0042] According to another illustrative example, the most significant bit (bit) of the message type field (Message type) (Most Significant Bit, MSB) is reserved until it is used. To implement a service configuration request, the high bit of this byte may be filled with the AP field, and it is agreed that when the AP value is 0, this means that the OMCI message is an OMCI message following the current ITU-T G.988 standard format, when the value of AP is 1, which means that the OMCI message is an OMCI message for service configuration.

[0043] According to another illustrative example, when the ONU needs to make a request for a service, it uses a managed entity that complies with the current ITU-T G.988 Managed Entity (ME) standard and sets the AP to 1. Parameters that the OLT must configure for the ONU , these are T-CONT and Alloc-ID profiles, AP=1 means the OMCI message is an OMCI message requesting for service configuration. When the OLT receives this message, it can confirm that it needs to assign an Alloc-ID for the T-CONT with ME ID 0x8001 on the current ONU, and other parameters should be controlled as reported by the ONU. Since the Alloc-ID is assigned by the OLT in a single order, the request only indicates that the Alloc-ID should be assigned, and does not indicate it. The processed OMCIs are shown in Table 1 below.

Table 1.

[0044] According to another illustrative example, the ONU performs the following operations on each of the received profiles before performing further operations:

[0045] First, the ONU receives a data collection request from the OLT.

[0046] The ONU then sets the MSB of the message type field in the OMCI message to a value indicating that the OMCI message sent to the OLT was used to request the service configuration.

[0047] Finally, the ONU sends a processed OMCI message to the OLT to inform the OLT that there is a subsequent service configuration request for the ONU.

[0048] According to another illustrative example, the ONU generates service configuration request information based on the previously acquired service information and based on the managed entities defined in the extension of the scope of this standard, this operation is performed in the following sequence, on which:

[0049] First, the ONU generates a management profile corresponding to the managed entity based on the previously acquired service information.

[0050] The ONU then uses the control profile as service configuration request information.

[0051] According to another illustrative example, when the ONU and OLT are located in the GPON system, the managed entity contains: a managed entity identifier and a managed entity attribute; the managed entity attribute contains: at least one service configuration request information and an identifier corresponding to this service configuration request information.

[0052] According to yet another illustrative example, when the size of one or more service configuration request messages is too large, messages that are too large may be split to allow serial transmission, where the split service configuration request information includes: at least one an integral part of the service configuration request information; where each item includes: service configuration request information of the corresponding item, an identifier corresponding to the item, and an identifier indicating whether the item is the last item of the service configuration request information.

[0053] According to yet another illustrative example, when the ONU and the OLT are located in the EPON system, the managed entity contains: a management attribute collection in which service configuration request attributes have been added, and information corresponding to the service configuration request attributes.

[0054] According to yet another illustrative example, when the characters of the information corresponding to the service configuration request attribute exceed the maximum payload of one Operation Administration and Maintenance Protocol Data Unit (OAM PDU), the ONU sends the request information to service configuration, while sending contains the following stages, at which:

[0055] First, the ONU divides the information corresponding to the service configuration request attributes in the control profile into information segments whose characters do not exceed the maximum payload of one OAM PDU.

[0056] The ONU then sends the received information segments to the OLT in turn.

[0057] According to the service configuration method proposed by this embodiment, the ONU requests the service configuration information from the OLT based on the previously acquired service information, and performs the service setup based on the service establishment information, automatic service setup is realized, thereby reducing the complexity of service activation. operator and increasing the efficiency of service activation.

[0058] Embodiments of the present invention also provide a service configuration method. In order to inform the OLT of the service configuration request information after the ONU connects to the OLT, based on the current format of the OMCI standard, this service configuration method extends certain message formats for marking OLT upstream messages as a request for service configuration information. As shown in figure 2, suppose that the services to be implemented are configured by a specific operator and include: Voice over Internet Protocol (Voice over Internet Protocol, VoIP) services, Data services (Data), and TV over Internet services. protocol (Internet Protocol Television, IPTV) based on IP, and in order to provide these services, we need to install the ONU in advance, and the ONU is used in plug-and-play engineering applications. The service configuration method presented in the embodiments of the present invention includes the following steps, in which:

[0059] First, the ONU system initializes, reads preconfigured services, retrieves service data, and builds object data according to various managed entities defined in ITU-T G.988, including:

1. T-CONT, two profiles.

2. GEM Port CTP, three profiles, among them two bi-directional are used for voice and data services, one uni-directional is used for downlink IPTV services.

3. Internet protocol host configuration data (IP Host config data), one profile is used by the DHCP method to obtain addresses, for voice services.

4. Tagging operation configuration data in Vlan(Extended Vlan tagging operation configuration data), two profiles, which in downstream mode two profiles is 0. Among them, one profile used for voice contains upstream direction rule RuleX (untag add Vid 30 Pbits 7) and the other profile used for the data contains the upstream RuleY (untag add Vid 40 Pbits5).

5. Vlan tagging filter data, one profile used for IPTV service where the Vlan list is Vid 200.

6. Profiles related to the ONU system defined by other standards

[0060] The ONU then connects to the OLT system and completes the authentication and authorization.

[0061] The OLT then starts the process of auditing the MIB and resynchronizing the MIB using the method defined in ITU-T G.988.

[0062] As shown in Figure 3, the MIB audit and synchronization process includes:

[0063] Step 201: Sending a data collection request from the OLT to the ONU, in particular, text content: Get (ONU data (MIB sync data)), text content: Get (ONU data (MIB sync data)).

[0064] Step 202: The ONU sends a response to the data collection request. The ONU response needs to set the value of the AP field to 1 to tell the OLT that the ONU needs to apply for a service configuration in the future, text content: Get response (AP=1).

[0065] If the OLT receives a response in which the value of the AP field is not set, steps 203, 204 are performed; if the OLT receives a response in which the value of the AP field is set, steps 205 and subsequent steps are performed.

[0066] Step 203: The OLT sends a MIB reset request, text content: MIB reset.

[0067] Step 204: The ONU sends a MIB reset response, text content: MIB reset response.

[0068] According to yet another illustrative example, when the OLT receives a MIB reset MIB response from the ONU, the OLT decides whether to perform a MIB reset according to the OLT ITU-T G.988 definition, and the ONU takes the appropriate action.

[0069] The management information base synchronization process then begins.

[0070] Step 205: The OLT sends a MIB upload request to the ONU, text content: MIBUpload.

[0071] Step 206: The ONU sends a MIB upload response to the OLT, text content: MIB Upload response.

[0072] The management information base synchronization process then begins.

[0073] Step 207: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0074] Step 208: The ONU sends a service configuration request to the OLT in terms of the media used to load the service in the GPON upstream, i. ONU marks T-CONT in MIB Upload next response message, text content: MIB Upload next (AP=1, ME class=T-CONT, ME ID=0x8001).

[0075] Step 209: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0076] Step 210: The ONU sends a service configuration request to the OLT to identify the port of the GPON encapsulation method, text content: GEM Port ID required for service activation, text content: MIB Upload next (AP=1, ME class=GEM CTP, ME ID=0x8001).

[0077] Step 211: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0078] Step 212: The ONU sends to the OLT a service configuration request used for the Internet protocol host configuration data, i. IP host configuration data for voice services in Dynamic Host Configuration Protocol (DHCP) mode, text content: MIB Upload next (AP=1, ME class=IP Host, IP options=Enable DHCP).

[0079] Step 213: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0080] Step 214: The ONU sends the tagging data configuration rules in the Vlan extension to the OLT, i. Extended Vlan tagging operation configuration data rules required for service development, text content: MIB Upload next (AP=1, ME class=EX Vlan op, ME ID=0x0101).

[0081] Step 215: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0082] Step 216: The ONU sends the VLAN tag filter data to the OLT, i. e. profile Vlan tagging filter data and Vlan list of its subsets required for IPTV services, text content: MIB Upload next (AP=1, ME class=Vlan filter, ME ID=0x0101).

[0083] Step 217: The OLT sends the service configuration information to the ONU, i. e. The OLT assigns Alloc-ID, GEM Port ID in a uniform order according to system resources, and builds a complete service configuration message and sends it to ONU according to the standard definition, text content: Create, Set (Alloc-ID, GEM Port ID , ...).

[0084] According to one illustrative example, the OLT configures the Vlan information of the PON port on the OLT terminal and the Eth port on the WAN terminal in accordance with the service configuration requirements

[0085] Step 218: The ONU sends a service configuration information receive message to the OLT, text content: Create, Set response.

[0086] According to yet another illustrative example, the ONU obtains service configuration information and completes the local service configurations according to the OLT configuration.

[0087] Next, after the MIB resynchronization process is completed, the OLT receives the Extended Vlan tagging operation rule table one by one, which the ONU needs to advertise using the standard defined Get, Get next messages.

[0088] Step 219: The OLT sends a rule information request, text content: Get, Get next (ME Class=EX Vlan op, ME ID=0x0101) to the ONU.

[0089] Step 220: ONU sends rule information to OLT, text content: Get, Get next response (AP=1, ME Class=EX Vlan op, ME ID=0x0101, Rule).

[0090] Embodiments of the present invention also provide a service configuration method that, in accordance with the class of managed objects defined in the scope extension of this standard for requesting a service configuration, to enable transmission of service configuration information to the OLT after the ONU connects to OLT. The standard framework applied is the ITU-T G.988 standard framework, the managed entities defined in the extension are the ONU Service Request (Service application for ONU), including Managed Entity id and Service table .

[0091] The ME Class object is the Service application for ONU, this object is the only profile with ME id=0 because it is used to represent all requests for service presentation on the ONU. The profile contains one table attribute that contains information used to describe the ONU service.

[0092] In accordance with the ITU-TG.988 standards framework, the service description information in the Service table is stored in multiple lines. The preferred option is that the service configuration request is represented by a row (separated by Row id). Row id is 0-based and is a unique keyword for marking and distinguishing different rows and is 2 bytes long.

[0093] Due to the limitations of the standard on the length of the data format, one line of information may consist of several parts (Row part id). The row part id is represented by the lower 7 bits of the 3rd byte and takes values in the range 0-127. The high bit of this byte indicates whether the current Row is the last part of the current row (separated by Row id), bit=0 means that the current Row part content is not the last. Bit=1 means that the content of the current part of the line is the last part of the whole line. "Row part content" contains each Row part that starts with id=0, arranged in sequence, forms information about the complete row.

[0094] ONU service configuration request information has been described. This embodiment is written and stored as an ASCII encoded string. An acceptable way to describe is JSON format. Assume that the service being implemented is shown in figure 2, then in JSON format it can be described as:

Row id=0 Row id=1 Row id=3

"Service name":"VoIP" "Service name":"Data" "Service name":"IPTV"

"T-CONT": "T-CONT": "GEM PORT":

{ { {

"Index":1 "Index":2 "Index":0xFFFF
"Policy":"Strict priority""Policy":"Strictpriority""Direction":2

} } }
"GEM PORT": "GEM PORT": "VLAN":

}"View":40

"Vlan": "Pbits":5

{}

Tag Number:1
"TPID":0x8100
"Vid":30
"Pbits":7

}

[0095] For the above defined Service application for ONU managed entities, the service configuration request message in Figure 2 can be divided into 3 lines.

1. When Row id=0, voice services are described, and at the same time, various resources and each objects are required.

2. When Row id=1, the data services are described while the resources of each objects are described in detail.

3. When Row id=2, the IPTV service is described because the IPTV service is in the downstream direction, so the description object does not include T-CONT resource information.

[0096] The service configuration method presented in the embodiments of the present invention includes the following steps.

[0097] First, the ONU system is initialized, the preset service is read, the service data is retrieved, the service configuration request message is described in the above JSON format, and the profile data is constructed according to the object definition of “Service application for ONU” in this embodiment. The above JSON data is divided into three rows and broken into row segments of appropriate length, which are stored in the Service table.

[0098] The ONU then connects to the OLT system and completes the authentication and authorization.

[0099] Finally, the OLT begins the process of auditing the control information base and synchronizing the control information base, as defined in ITU-T G.988.

[0100] As shown in FIG. 4, the management information base audit process and the management information base resynchronization process include the following operations.

[0101] Step 301: The OLT sends a data collection request to the ONU, text content: Get (ONU data (MIB sync data)).

[0102] Step 302: The ONU sends a response to the data collection request, text content: Get response.

[0103] Step 303: The OLT sends a MIB reset request, text content: MIB reset.

[0104] Step 304: The ONU sends a MIB reset response, text content: MIB reset response.

[0105] According to another illustrative example, when the OLT receives a MIB reset response from the ONU, the OLT decides whether to perform a MIB reset in accordance with the OLT ITU-T G.988 definition, and the ONU takes the appropriate action.

[0106] The management information base synchronization process then begins:

[0107] Step 305: The OLT sends a MIB upload request to the ONU, text content: MIBUpload.

[0108] Step 306: The ONU sends a MIB Upload response to the OLT, text content: MIB Upload response.

[0109] Step 307: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0110] Step 308: The ONU sends a response to the OLT to the next upload request to upload the control information base, text content: MIB Upload next response.

[0111] At the same time, the interaction process is completed.

[0112] Step 309: The OLT sends the next MIB upload request to the ONU, text content: MIB Upload next.

[0113] Step 310: The ONU sends to the OLT a management profile corresponding to the managed entity, text content: MIB Upload next response (ME Class=Service application for ONU).

[0114] Step 311: The OLT sends a get management profile request to the ONU, i.e., all “Service table” data in the “Service application for ONU” profile is retrieved to the OLT via Get/Get next information as defined in ITU- T G.988, text content: Get, Get next (ME Class=Service application for ONU).

[0115] Step 312: The ONU sends a response to the request to the OLT, text content: Get, Get nextresponse (ME Class=Service application for ONU, Service table).

[0116] Step 313: The OLT sends the service configuration information to the ONU, i. e. The OLT assigns Alloc-ID, GEM Port ID in a unified order according to system resources, and builds complete service configuration information according to the standard definition and sends it to ONU, text content: Create, Set (Alloc-ID, GEM Port ID , ...).

[0117] According to one illustrative example, the OLT parses ONU service configuration request information according to the definition of “Service application for ONU”.

[0118] According to another illustrative example, the OLT configures the Vlan information of the PON port on the OLT terminal and the Eth port on the WAN terminal in accordance with the service configuration requirements.

[0119] Step 314: The ONU sends a service configuration information receive message to the OLT, text content: Create, Set response.

[0120] According to yet another illustrative example, the ONU obtains service configuration information and completes the local service configuration according to the OLT configuration.

[0121] Embodiments of the present invention also provide a service configuration method that, in accordance with the current scope of the standard, extends the definition of a managed object class for requesting a service configuration to enable transmission of service configuration information to the OLT after the ONU is connected to the OLT. The applicable framework is the IEEE 1904.1 framework, the existing set of management attributes "aOnuCapabilitiesExt" is defined in the service configuration request attribute extension "ServiceAppInfo". The added service configuration request attributes in the set of control attributes and service configuration request information corresponding to the specified service configuration request attribute are respectively shown in Tables 2 and 3 below. The tables indicate the size of the current service configuration request data downloaded by the ONU, and 0 indicates no service configuration request data.

[0122] When the content of the Service application information from the ONU exceeds the maximum payload capacity of the OAM PDU, the sequence number (Sequence) used to annotate the current response information is added before the TLV (Type-Length-Value) in accordance with IEEE 1904.1, i.e. . Sequence TLV is used.

[0123] To describe the ONU service configuration request information, this implementation is written and stored as an ASCII encoded string, JSON format is an acceptable way to describe. Assume that the service being implemented is shown in figure 5, then in JSON format it can be described as

[0124] The service configuration method presented in the embodiments of the present invention includes the following steps.

[0125] First, the ONU system is initialized, the preset service is read, the service data is retrieved, the service configuration request information is described in the JSON format described above, and the data is built according to a certain attribute in the "Service application for ONU" extension defined in the embodiments of the present invention. The above JSON data is Cache characters in ASCII encoding.

[0126] The ONU then connects to the OLT system and completes the authentication and authorization.

[0127] Finally, as shown in figure 6, this method contains the following steps:

[0128] Step 401: The OLT and the ONU sequentially go through the discovery and registration process, the generic OAM discovery process, and the OAM extension discovery process, i. Multipoint Control Protocol (MPCP) discovery registration, generic OAM discovery, and OAM extension discovery are completed in accordance with IEEE 1904.1.

[0129] Step 402: The OLT sends a request for service configuration information to the ONU, i. e. The OLT obtains the attribute in the aOnuCapabilitiesExt extension of the ONU based on the eOAM_Get_Request information and according to the IEEE 1904.1 standard, the content of the text is: eOAM_Get_Request (aOnuCapabilitiesExt).

[0130] If the ONU needs to request configuration information, it reports the symbol cache size for the service configuration request information in the ServiceAppInfo attribute, and proceeds to step 403; if the ONU does not need to request service configuration information, it sets the ServiceAppInfo sub-attribute to 0 and proceeds to step S407.

[0131] Step 403: The ONU sends a response to the OLT, text content: eOAM_Get_Response(aOnuCapabilitiesExt::ServiceAppInfo).

[0132] Step 404: The OLT sends a request to obtain details of the service configuration request to the ONU, i. e. The OLT obtains attribute details in the Servic application for ONU extension via eOAM_Get_Request information, text content: eOAM_Get_Request (Service application for ONU).

[0133] If the symbol cache size of the requested ONU service does not exceed the maximum payload of one OAM PDU, i. e. no more than 1490 bytes, then step 404 is performed, otherwise go to step 405.

[0134] Step 405: The ONU sends a response to the OLT, i. e. reports an attribute in the Service application for ONU extension via eOAM_Get_Response information, and carries service configuration request information via the Detail sub-attribute, text content: eOAM_Get_Response (Service application for ONU).

[0135] Step 406: The ONU sends a response in segments to the OLT, i. e. communicates the attribute in the Service application for ONU extension via multiple eOAM_Get_Response messages and inserts a Sequence TLV before the length value of this type (ag Length ValuTLV). the Detail sub-attribute of each application for ONU sub-property Detail carries a fragment of service configuration request information and marks the fragment with a Sequence TLV. Text content: eOAM_Get_Response (Sequence TLV #0x0000；Service application for ONU eOAM_Get_Response (Sequence TLV #0x8000；Service application for ONU).

[0136] According to one illustrative example, the OLT parses ONU service configuration request information from the "Service application for ONU" information loaded by the eOAM_Get_Response message.

[0137] In accordance with the IEEE 1904.1 standard, the above Sequence TLV must comply with the following principles:

1. The SequenceNumber field in the first OAM PDU is filled with 0, i.e. the sequence number starts at 0.

2. The LastResponse field in the last OAM PDU is set to the binary value 1, indicating that the current slice is the last slice.

3. The SequenceNumber field in all OAM PDUs is incremented in order.

[0138] Step 407: The OLT sends the service configuration information to the ONU, i. e. The OLT assigns LLID, Vlan services in a unified manner according to system resources.

[0139] In illustrative examples, the OLT configures the Vlan information of the PON port on the OLT and the Eth port on the WAN terminal in accordance with the service configuration requirements.

[0140] Step 408: The ONU sends a service configuration information reception message to the OLT.

[0141] According to another illustrative example, the ONU obtains service configuration information and completes the local service configuration according to the OLT configuration.
