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.
The invention provides a network group message management method, as shown in fig. 1, the method comprises the following steps:
in step S1, the new member sends a request for obtaining the original group message to the session management function entity. The method specifically comprises the following steps:
the original group is a group established by an old member, and after the old member establishes the group, the group session relationship is established. In the group session, the message sent by any one member can be received by other members at the same time. Thus, even if an old member exits the group, the group message generated by the old member session is stored by other old member terminals still in the group.
When a new member joining the group wants to obtain an original group message in the group, the new member sends a request for obtaining the original group message to a Session Management Function (SMF).
It should be noted that, in this embodiment, the request sent by the new member includes the group session identifier of the group. In addition, the original group message in this embodiment refers to a group message generated by a session between members in the group before the new member joins the group.
In some embodiments, the new member may include a key in the request. If the keyword is contained, the new member only requests the original group message matched with the keyword; if the key is not included, it indicates that the new member requests all messages.
In other embodiments, the request from the new member may also include a time constant. If the Current is contained, the new member requests the original group message among all the old members in the Current group; if "All" is included, it means that the new member requests the original group message between the current and All the old members who have joined the group.
Step S2, the SMF entity queries the user plane functional entity corresponding to the group and forwards the request to the user plane functional entity. The method specifically comprises the following steps:
each group corresponds to a group session, and the group session correspond to a group session identification number. In addition, the new member joining the group will cause the group session of the group to change, i.e. the original group and the group to which the new member joined are two different groups, and the group session identification number is updated correspondingly with the change of the group session. The SMF entity is responsible for session management, such as session establishment, modification and release; it is also responsible for the selection and control of User Plane Function (UPF) entities. Therefore, the SMF entity stores a mapping relationship between the group and the UPF entity providing the group session service for the group.
After receiving the request of a new member, the SMF entity queries a UPF entity providing service for the current group session according to the group session identification number carried in the request, and forwards the request for acquiring the original group message sent by the new member to the UPF entity.
In step S3, the UPF entity receives the request and queries the original group message. The method specifically comprises the following steps:
the joining of a new member to a group causes a change to the group session for the group to generate group session update data, which is recorded by the UPF. In addition, the UPF entity providing group session service for the group has a plurality of group session caches, and the group session caches are distinguished by group session identifiers.
After receiving the request for acquiring the original group message forwarded by the SMF entity, the UPF entity queries the original group session identification number before the new member joins according to the group session identification number carried in the request and the group session update data stored in the UPF, and queries the original group session cache according to the original group session identification number.
If the original group message is reserved in the original group session cache, the UPF entity sends the original group message in the original group session cache to the new member and returns a message identification number of the original group message provided for the new member to the SMF entity; and if the original group session cache does not retain the original group message, the UPF entity returns the original group session cache non-original group message to the SMF entity.
And step S4, the SMF entity forwards the request for acquiring the original group message to the old member according to the feedback of the UPF entity. The method specifically comprises the following steps:
in some embodiments, the SMF entity receives the original group session cache no-original-group message returned by the UPF entity, and the SMF entity forwards the request for obtaining the original group message to the old member currently still remaining in the group. In other embodiments, the SMF entity receives the message identifier of the original group message provided to the new member returned by the UPF entity, and the SMF entity sends a request for obtaining the original group message to the old member still remaining in the group, where the request includes the message identifier returned by the UPF entity.
The following description takes the example that the UPF entity returns the message identifier of the original group message provided to the new member to the SMF entity.
In step S5, the senior receives the request and searches for the original group message and the corresponding message identifier. The method specifically comprises the following steps:
and the old member receives a request for acquiring the original group message sent by the SMF entity, if the request is a non-repeated request, the old member searches the original group message and a corresponding message identification number in the locally cached group session message respectively, and sends the searched message identification number to the SMF entity, wherein the message identification number does not include the message identification number of the original group message sent to the new user by the UPF entity.
If the request forwarded by the SMF entity received by the old member is a repeatedly sent request and the new member has received the original group message, the old member can refuse to respond to the request.
The following description takes as an example the older adult receiving a non-duplicate request and returning a message identification number to the SMF entity.
And step S6, the SMF entity receives the message identification number returned by the old member and performs rearrangement, and distributes the rearranged message identification number to different old members. The method specifically comprises the following steps:
after the SMF receives the message identifiers returned by all the old members, the SMF needs to exclude the duplicated message identifiers because the message identifiers returned by the old members have duplicated parts, for example, two or more old members store the same original group message, and these old members provide the same message identifiers to the SMF. Therefore, when the SMF entity receives the message identification numbers of the original group message returned by the old members, the message identification numbers are rearranged first, and then the rearranged message identification numbers are distributed to different old members, so that the old members do not provide the original group message repeatedly.
In this embodiment, the distribution principle of the SMF may be preset, for example, the distribution of the message identification number may be reasonably performed according to the number of messages or the length of the messages.
Specifically, if the message identifiers returned by the first old member are 1, 2, 3 and 4, the message identifiers returned by the second old member are 4, 5 and 6, and the message identifiers returned by the third old member are 2, 5 and 7, the result of the average number distribution is: message identifiers 1, 3, 4 are assigned to the first old member, message identifiers 5, 6 are assigned to the second old member, and message identifiers 2, 7 are assigned to the third old member.
And step S7, the old member receives the message identification number of the original group message distributed by the SMF entity and sends the original group message corresponding to the message identification number to the UPF entity.
In step S8, the UPF entity receives the original group message sent by the old member and sends the original group message to the new member.
In step S9, the SMF entity returns a message that the forwarding of the original group message is completed to the new member.
In the method for managing network group messages provided by this embodiment, when a new member joining a group wants to obtain an original group message in the group, the original group message can be automatically obtained only by sending a request for obtaining the original group message to the SMF entity, and the obtaining process is simple and fast, thereby improving the efficiency. In the embodiment, receiving an original group message corresponding to the aging member and an identification number of the message returned by the aging member; and the old member provides the corresponding original group message according to the message identification number, thereby greatly reducing the repetition rate of the original group message.
