The embodiments of the present invention will be described below with reference to the drawings.
Fig. 1 shows a flowchart of a method for grouping live users according to an embodiment of the present invention. The method is implemented by an access device and a central device, and implements hierarchical management on users, as shown in fig. 1, the method includes:
step 101: the entrance device receives a login request initiated by a current user, and determines a current user group to which the current user belongs according to the login request.
In the embodiment of the invention, the entrance equipment is used for a user to log in the live broadcast service; generally, the number of the access devices is multiple, so that users in different regions can conveniently log in nearby. For example, when a user in Beijing needs to watch a live video, he may initiate a login request based on the portal device in Beijing to log in to the live service to watch the live. In addition, each user is pre-assigned with a corresponding user group, and one user may be assigned with one user group or multiple user groups. When the portal device receives a login request of a current user, the portal device can determine which user group the current user belongs to, that is, the portal device can determine that the current user belongs to the current user group. The corresponding relation between each user and the user group can be pre-stored in the access device, and when the login request of the current user is obtained, the user group to which the current user belongs can be determined based on the corresponding relation between the users and the user groups; or, the login request initiated by the current user may include that the current user belongs to the current user group, and at this time, the current user may also be directly determined to belong to the current user group based on the login request.
Step 102: the portal device adds the current user to the current user group to update the local portal packet data for recording the user group to which the user logged in by the portal device belongs.
In this embodiment, the portal device may record all users logged in to the portal device and user groups to which the users belong, in addition to providing a login portal for the users. In this embodiment, the portal device stores data for recording a user group to which a user registered by the portal device belongs, that is, portal packet data. After the current user is successfully logged in, the current user can be added to the corresponding current user group in the ingress packet data. Wherein, the entrance grouped data record has one or more user groups, and each user group contains users belonging to the user group. Referring to fig. 2, it is assumed that there are currently six entrance devices, and the three regions are divided according to beijing, shenzhen, and hangzhou, and each region includes two entrance devices, for example, the two entrance devices of beijing are "beijing entrance 1" and "beijing entrance 2" in fig. 2, respectively. Taking the example of watching live broadcast 1 as an example, if a user 1 in beijing initiates a login request to beijing portal 1, if the user 1 belongs to group 1 (i.e. the first user group), the portal group data of the beijing portal 1 records that the user 1 belongs to group 1. Similarly, when a user 5 logs in Shenzhen entry 1, the entry packet data record of Shenzhen entry 1 indicates that the user 5 belongs to packet 2. Fig. 2 shows ingress packet data for six ingress devices, which may represent the packet status for each ingress device. Like beijing ingress 1, the ingress packet data may indicate that user 1 belongs to packet 1, that user 2 and user 3 belong to packet 2, and that user 4 belongs to packet 3.
Step 103: the entrance device sends a login success message to the central device, wherein the login success message comprises the grouping information of the current user.
In the embodiment of the invention, after the current user successfully logs in, the entry device can send a login success message to the central device, wherein the login success message can be a message regenerated by the entry device; if the login request initiated by the current user can indicate which user group the current user belongs to, the login request can also be directly used as a login success message. The grouping information of the current user is used to indicate which user group the current user belongs to, for example, the grouping information may include an identifier of the current user and an identifier of the user group to which the current user belongs.
Step 104: after receiving the login success message, the central device adds the current user to the current user group to update local central grouped data, wherein the central grouped data is used for recording the user groups to which all users in the login state belong.
In the embodiment of the present invention, the central device is a device of a unified management user, and may be in communication connection with one or more entry devices to receive a login success message sent by the central device. After receiving the login success message, the central device may determine, based on the group information therein, which user (i.e., the current user) is currently logged in the portal device, and may determine the user group to which the user belongs, i.e., the current user group. Similar to the ingress packet data of the ingress device, the central device also stores data for recording the user group to which the user belongs, i.e., the central packet data. The difference between the two is that the portal grouping data only records the users logged in by the corresponding portal equipment and the user groups to which the users belong; the central device can receive the login success messages sent by all the portal devices, so that all the users in the login state and the user groups to which the users belong are recorded in the central grouped data. If the current status of the inlet device is as shown in fig. 2, the corresponding status of the central device can be seen in fig. 3; fig. 3 shows the center packet data stored by the center device, for example, user 1, user 9, user d, etc. belong to packet 1.
In the embodiment of the invention, the method is based on the fact that the entrance equipment at the entrance and the center equipment at the center side jointly manage the users watching the live broadcast, and the hierarchical management of the users is realized; even if multiple users log in through the access devices in different regions, the central device can store all user groups to which the users belong, and any type of messages can be routed based on the central device. In particular, the method further comprises a process of sending a message, which comprises in particular step a1 and/or step a2 described below.
Step A1: when a first message needs to be sent to a target user group, the central equipment determines inlet equipment related to the target user group according to the central grouping data and broadcasts the first message to the inlet equipment related to the target user group; and after receiving the first message, the inlet equipment related to the target user group determines a first target user related to the target user group according to the inlet grouping data, and sends the first message to all the first target users.
Step A2: the central grouped data also comprises inlet equipment corresponding to each user, and when a second message needs to be sent to a second target user, the central equipment determines the inlet equipment corresponding to the target user according to the central grouped data and sends the second message to the inlet equipment corresponding to the target user; the portal device corresponding to the target user sends a second message to a second target user.
In the embodiment of the present invention, the central device may broadcast the message in units of groups. Specifically, when the first message needs to be sent to all users in a certain user group, the user group may be regarded as a target user group, and each user in the group is a first target user. At this time, the center device may broadcast the first message to the ingress devices associated with the target user group, so that the ingress devices may further transmit the first message to the corresponding first target users. As shown in fig. 3, if the central device needs to send a first message to group 1, that is, group 1 is a target user group; as can be seen from fig. 2, the beijing portal 1, the beijing portal 2, the hangzhou portal 1, and the hangzhou portal 2 all have the packet 1, so that the four portal devices are portal devices associated with the target user group, and can determine a user associated with the packet 1, i.e., a first target user, based on local portal packet data, and send the first message to the associated user. For example, the hang state portal 2 sends a first message to user i and user n, both of which are first target users.
As will be understood by those skilled in the art, since the central device sends the first message in a broadcast manner, it is not necessary to determine which portal devices need to be broadcasted at this time, that is, all the portal devices may be regarded as the portal devices related to the target user group, and the first message is broadcasted to all the portal devices at this time; after receiving the broadcast message, the ingress device continues to issue the first message if the local ingress packet data includes the target user group, otherwise, the message broadcast by the central device is ignored.
Alternatively, the central device may send a message to a user at a fixed point. In this embodiment, the central packet data recorded by the central device further includes an ingress device corresponding to each user; as shown in fig. 2, the user 1 is logged in based on the beijing portal 1, that is, the user 1 corresponds to the beijing portal 1, and the central grouping data records the correspondence between the user 1 and the beijing portal 1. When a specific user is required to send a second message, the specific user is used as a second target user, the central device can determine the access device corresponding to the second target user based on the central packet data, and then the second message is sent to the corresponding access device, so that the access device can send the second message to the second target user. For example, in fig. 2, the user 1 requests to send a second message to the user 9, since the user 1 is logged in to the beijing portal 1 and the user 9 is logged in to the hangzhou portal 1, which cannot implement message interaction based on the portal device, and this can be implemented based on the central device. Specifically, when the central device determines that the second message needs to be sent to the user 9, it may be determined based on the central packet data that the user 9 is logged in the hangzhou entry 1, at this time, the second message may be sent to the hangzhou entry 1, and then the hangzhou entry 1 sends the second message to the user 9, thereby implementing message communication across the entries.
In addition, optionally, the ingress device and the central device both store corresponding packet data, which can also improve reliability. In this embodiment, the method further includes:
step B1: when the central equipment is restarted, the entrance equipment sends entrance grouping data to the restarted central equipment.
Step B2: and the restarted central equipment generates local central grouped data according to the inlet grouped data.
In the embodiment of the present invention, in order to ensure the efficiency of querying the user, the packet data may be stored in the memory, that is, the ingress packet data is stored in the memory of the ingress device, and the central packet data is stored in the memory of the central device. If the central device is abnormally stopped, the central grouped data in the memory can be cleared, if the central device is restarted later, because the inlet grouped data is stored in the inlet device, the inlet device can send the inlet grouped data stored in the inlet device to the central device at one time, so that the central device can regenerate the central grouped data containing a full amount of users based on the inlet grouped data of all the inlet devices, and the central device can also quickly recover the working state when the central device is stopped and restarted for a short time.
In this embodiment, the number of the center devices may be multiple, for example, two, and at this time, even if one center device is shut down, the other center device can still normally operate, so that the reliability can be further improved. The access device can send login success messages to all the central devices in a broadcasting mode, so that different central devices can receive the login success messages, and the same central grouped data is generated and stored for subsequent use.
The method for grouping the live broadcast users, provided by the embodiment of the invention, manages the users watching the live broadcast based on the entrance equipment at the entrance and the central equipment at the central side together, and realizes the hierarchical management of the users; even if multiple users log in through the access devices in different regions, the central device can store all user groups to which the users belong, and any type of messages can be routed based on the central device. The full packet data is directly stored in the central equipment, for example, the memory of the central equipment, so that a database such as redis and the like is not needed; when a user needs to be inquired, the user can directly inquire based on the central grouped data of the central equipment without accessing a server through a network, and the inquiring efficiency is high. The inlet equipment and the central equipment store corresponding grouped data, and reliability can be improved.
On the basis of the above embodiment, when a user logs out or an ingress device fails, the corresponding user in the packet data (including the ingress packet data and the central packet data) needs to be deleted, so as to ensure that all users recorded in the packet data are users in the login state. In this embodiment, the method further includes: a multi-user deletion procedure and/or a single-user deletion procedure. Wherein, the multi-user deleting process comprises:
step C1: when the entrance device is off-line, the center device deletes the user related to the off-line entrance device from the corresponding user group to update the local center grouping data.
The single-user deletion process comprises:
step D1: the entrance device receives a log-in request initiated by a current user, and deletes the current user from the current user group to update local entrance packet data.
Step D2: the portal device sends a logout message to the central device.
Step D3: after receiving the log-out message, the center device deletes the current user from the current user group to update the local center grouping data.
In the embodiment of the invention, when the inlet equipment is in fault and offline, a multi-user deleting process can be executed. Specifically, if a certain ingress device goes offline and is unable to communicate with the central device, the central device may delete the user associated with the ingress device from the central packet data. As shown in fig. 2 and fig. 3, if the beijing portal 1 fails, the user 1, the user 2, the user 3, and the user 4 may be offline, and the central device may not communicate with the beijing portal 1, at this time, the central device may delete the user 1, the user 2, the user 3, and the user 4 in its central packet data. Optionally, when the beijing portal 1 fails, the user 1 and the like may be automatically accessed to the beijing portal 2, and at this time, the beijing portal 2 sends the login success message of the user 1 to the central device, so that the central device adds the user 1 to the portal packet data again.
If a user logs out actively, the single-user deleting process can be executed. Specifically, if the current user initiates a logout request, the portal device may delete the current user from the portal packet data, and send a logout request indicating that the current user logs out to the central device, so that the central device also deletes the current user in the central packet data. By deleting the users, the users recorded in the grouped data can be guaranteed to be all users in the login state.
The flow of the method is described in detail below by means of an example. Referring to FIG. 4, the method includes steps 404-411:
step 401: user a sends a login request to the portal device, the login request including the identity of user a.
The user A can initiate a login request based on a client such as a smart phone and a tablet computer, the identifier of the user A can be uniquely located to which user the identifier identifies, and the identifier can be a user name, a mobile phone number, an identity card number and the like of the user A.
Step 402: and the entrance equipment determines a corresponding user group to which the user A belongs according to the login request, and adds the user A to the corresponding user group so as to update local entrance packet data.
Step 403: the portal device transmits a login success message including the grouping information of the user a to the center device.
In the embodiment of the present invention, when the user a successfully logs in, the above steps 402 and 403 are executed, and the execution sequence of the two steps is not limited.
Step 404: and after receiving the login success message, the central equipment adds the user A to a corresponding user group so as to update the local central grouped data.
Step 405: when a message needs to be sent to the user A, the central equipment determines the entrance equipment corresponding to the user A according to the central grouping data.
Step 406: the central device sends the message to the portal device corresponding to user a.
Step 407: the portal device sends the message to user a.
Step 408: user a initiates a logout request to the portal device.
Step 409: the ingress device removes user a from the corresponding user group to update the local ingress packet data.
Step 410: the portal device sends a logout message to the central device.
Step 411: after receiving the log-out message, the center device deletes the user A from the corresponding user group to update the local center packet data.
The method for grouping the live broadcast users, provided by the embodiment of the invention, manages the users watching the live broadcast based on the entrance equipment at the entrance and the central equipment at the central side together, and realizes the hierarchical management of the users; even if multiple users log in through the access devices in different regions, the central device can store all user groups to which the users belong, and any type of messages can be routed based on the central device. The full packet data is directly stored in the central equipment, for example, the memory of the central equipment, so that a database such as redis and the like is not needed; when a user needs to be inquired, the user can directly inquire based on the central grouped data of the central equipment without accessing a server through a network, and the inquiring efficiency is high. The inlet equipment and the central equipment store corresponding grouped data, and reliability can be improved.
