Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
D2D (Device to Device) communication is a new technology proposed by the 3GPP (3rd Generation partnership project) organization that allows terminals to communicate directly with cell resources without infrastructure under the control of a communication system. The D2D technology can improve the spectrum efficiency of the communication system and solve the problem of the lack of the spectrum resources of the wireless communication system to a certain extent. Meanwhile, the D2D technology can also effectively reduce the terminal transmitting power, reduce the battery consumption and prolong the endurance time of the mobile phone. Even in the case of no network coverage, a terminal using the D2D technology can perform short-range communication.
The application of D2D (Device to Device) may relieve the terminal from pressure to transfer data through the base station. As shown in fig. 1-a, by using D2D technology, two end users under the same base station communicate with each other, and data between the two end users can be directly transmitted to each other without being forwarded by the base station. Fig. 1-b is another form of D2D data exchange, where data and signaling can be exchanged between two end users without the participation of a base station.
The D2D technique classifies user rights into classes 2: restricted discovery and open discovery. The restriction finding means that: the terminal is not allowed to be detected without explicit permission. The public discovery means that: as long as the current terminal is a neighbor of another device, it may be detected and a connection established.

Example 2
The present example provides a method of establishing a group registration profile. Suppose that handset a, handset B, handset C and handset D all open D2D communication and set the user right to public discovery.
As shown in fig. 5, a method of establishing a group registration profile may include the steps of:
step S101, a group initiator (group owner) creates a group, searches for peripheral equipment and obtains equipment information of the peripheral equipment;
the group initiator (mobile phone A) names the new group, then searches surrounding mobile phones in a D2D communication mode, obtains the distribution conditions of the surrounding mobile phones, discovers mobile phone B, mobile phone C and mobile phone D, and obtains the equipment information of each mobile phone.
Wherein the device information of the D2D device may be: device identification, Media Access Control (MAC) address of the device, and a Control request for the device,
Wherein the device identification may be: IMEI (International Mobile Equipment Identity number), IMSI (International Mobile Subscriber Identity), device name, or owner name modified by the user.
Step S102, a group initiator (group owner) determines a group member list according to the searched D2D equipment;
for example, the group list includes: mobile phone a, mobile phone B, mobile phone C and mobile phone D.
Step S103, the group initiator (group owner) establishes contact with the group members;
the group initiator can establish contact with each member in the group respectively. The group owner sends a request for establishing contact (called a request for establishing contact for short) to a certain group member, and if a response instruction returned by the group member is received and indicates that the group member agrees to establish contact, the group owner judges that the contact is established successfully; and if the response instruction returned by the group member is not received, judging that the connection establishment is failed.
For example, the group owner (mobile phone a) sends a connection establishment request to the mobile phone B in a D2D communication manner, the mobile phone B authenticates the connection establishment request sent by the mobile phone a, and if the connection establishment request meets a preset condition, the mobile phone B returns a response instruction to the mobile phone a to indicate agreement to establish contact. If the condition is not met, the mobile phone B displays a notification message waiting for the manual confirmation of the user, if the manual confirmation of the user is obtained later, the mobile phone B returns a response instruction to the mobile phone A to indicate that the establishment of the contact is agreed, and if the manual confirmation of the user is not obtained later, the mobile phone B reserves the notification message waiting for the manual confirmation of the user and waits for the processing of the user.
For the group members, the preset condition may be a matched member in the address list, or an appointed proprietary name, etc.; where the agreed upon proper names are such as: a certain department, a certain group, etc.
The group owner and the group members may also exchange information, such as a contract communication key, a group name, an attachment size limit, etc., within a period of time (e.g., 30 minutes) after the group owner sends the association request.
Step S104, the group initiator (group owner) establishes a group registration configuration table;
the group registration configuration table comprises registration information of all group members in a group;
wherein, the group registration configuration table can be a configuration file;
wherein the registration information of the group member may include the following information: member equipment identification, member management authority, member temporary authority and a shared information release list;
wherein the member device identification comprises: IMEI, IMSI, device name, or owner name modified by the user, etc.
Wherein the member management authority comprises: group owner or general group member;
wherein the member temporary permission comprises: a main control end (host) and a client end (client); the client side has the authority of receiving the information but does not have the authority of issuing the information;
the shared information publishing list records a shared information attribute list of all shared information sorted according to publishing time;
wherein the shared information attribute comprises at least one of the following: the information issuing method comprises the following steps of information issuers, information issuing time, a received member list, information names, information types and information sizes;
step S105, the group initiator sends a group registration configuration table to the group members;
the group initiator may send the group registration configuration table to each member in the group, or may send the group registration configuration table to all members in the group in a broadcast manner.
Wherein the broadcast may send the group registration configuration table to all group members on one channel or multiple channels;
after receiving the response message, the group owner can set the receiving state of the group registration configuration table of the group member to a received state in the group registration table; if a group member does not receive the group registration configuration table sent by the group owner, the group owner may set the receiving state of the group registration configuration table of the group member to a non-receiving state, or the group owner may also resend the group registration configuration table to the group member;
for example, when the mobile phone B and the mobile phone C receive the group registration configuration table sent by the group owner, the group owner sets the state of the group registration configuration table received by the mobile phone B and the mobile phone C as the received state; if the mobile phone D does not receive the group registration configuration table sent by the group owner, the group owner may set the state of the group registration configuration table received by the mobile phone D to the unreceived state, or the group owner may resend the group registration configuration table to the mobile phone D.
Example 3
The present example provides a group information sharing method. Assume that a group has been established between cell phone a, cell phone B, cell phone C and cell phone D. The group members want to share information, and the shared information comprises: documents, pictures, videos, music, etc.
As shown in fig. 6, a group information sharing method may include the steps of:
step S101, a mobile phone (such as a mobile phone A) which needs to issue information at present modifies a group registration configuration file, and sets a temporary authority of the mobile phone as a main control end (host) in the group registration configuration file;
step S102, establishing contact between the current mobile phone (such as the mobile phone A) needing to release information and other group member mobile phones;
for example, the mobile phones of other group members include mobile phone B, mobile phone C and mobile phone D, and then mobile phone a may establish a connection with mobile phone B, mobile phone C and mobile phone D respectively in a point-to-point connection establishing manner;
step S103, the mobile phone (such as the mobile phone A) which needs to issue information at present sends the modified group registration configuration file to the mobile phones of other group members which have established contact in the step S102;
when the local computer needs to send information or attachments, the temporary authority of the local computer can be modified into host in the registry, then the modified registry is transmitted to other members of the group, and then the information or attachments are sent. For example, when a user clicks to send on a mobile phone interface, the information or the attachments can be first put into a local cache, and after the local host setting is completed and the group is synchronized, the information or the attachments are sent, so that the communication record of the whole group is maintained by using the registry as a carrier.
The mobile phone (for example, the mobile phone a) that needs to issue information currently may send the updated group registration configuration file to other group member mobile phones one by one, or may send the group registration configuration file to all group members on one or more channels in a broadcast manner.
After receiving the updated group registration configuration file, if other group member mobile phones also want to issue information, the information is sent after the information of the mobile phone A is issued;
step S104, the mobile phone which needs to release information sends the information which needs to be shared to other mobile phones of group members;
the mobile phone (mobile phone a) that needs to issue information currently can set itself as a hotspot, and other mobile phones can actively scan the hotspot, access the hotspot through a group key, and then acquire the information issued by the mobile phone a. Or the mobile phone A can establish point-to-point connection with other group member mobile phones to transmit information;
step S105, the mobile phone (mobile phone A) which issues the shared information updates the group registration configuration file according to the condition that other mobile phones of group members receive the shared information, and adds an information issuing record in the shared information issuing list, wherein the information issuing record comprises the attribute information of the shared information;
when a group member accesses a hotspot (mobile phone A), both the mobile phone A and the group member perform authentication, check keys, member mobile phone identifiers and the like, at the moment, the mobile phone A can match the mobile phone accessing the hotspot with the members in the registry, and determine which mobile phones receive shared information according to the matching condition and which mobile phones do not receive the shared information.
Wherein the attribute information of the shared information includes: the information issuing method comprises the following steps of information issuers, information issuing time, a received member list, information names, information types and information sizes;
step S106, the mobile phone (mobile phone A) which issues the sharing information sends the updated group registration configuration file to other mobile phones of the group members;
step S107, the other group member mobile phones receive the updated group registration configuration file to synchronize the locally stored group registration configuration file, and the group completes one-time information release.
Example 4
The present example provides a method of obtaining group sharing information. It is assumed that a group member (mobile phone C) does not receive the updated group registration configuration file and the published shared information from the temporary master control terminal (mobile phone a) with an earlier information publication time, but receives the shared information and the updated group registration configuration file published from the temporary master control terminal (mobile phone B) with a later information publication time, synchronizes the locally stored group registration configuration files, and finds that the group member does not receive the shared information from the mobile phone a in the process of synchronizing the group registration configuration files. The handset C can retrieve the missing information by the following method.
As shown in fig. 7, a method for acquiring missing group sharing information may include the following steps:
step S101, a group member (mobile phone C) finds that the sharing information of a first group member mobile phone (mobile phone A) is lost in the process of synchronizing the group registration configuration file;
step S102, a group member (mobile phone C) initiates a synchronization request to a first group member mobile phone (mobile phone A), wherein the synchronization request carries attribute information of shared information to be acquired;
step S103, the group member (mobile phone C) fails to successfully acquire the shared information to be acquired from the mobile phone of the first group member, and initiates a synchronization request to the mobile phone of the second group member (mobile phone D), wherein the synchronization request carries the attribute information of the shared information to be acquired;
step S104, the group member (mobile phone C) successfully acquires the sharing information to be acquired from the second group member mobile phone (mobile phone D), updates the group registration configuration file, modifies the information issuing record corresponding to the acquired sharing information in the sharing information issuing list, and adds the identification of the mobile phone in the received member list of the sharing information;
step S105, the group member (mobile phone C) establishes contact with other group member mobile phones, and sends the updated group registration configuration file to other group member mobile phones.
Example 5
The present example provides a method of adding a group member. As shown in fig. 8, a method of adding group members may include the steps of:
step S101, a mobile phone (such as a mobile phone A) which needs to invite other mobile phones to enter a group currently updates a group registration configuration file, and a temporary authority of the mobile phone is set as a main control end (host) in the group registration configuration file;
step S102, the mobile phone A searches the peripheral equipment, takes the newly found mobile phone (such as the mobile phone E) as the mobile phone of the invitee, and adds the mobile phone of the invitee to a group member list;
for example, the group list includes: mobile phone a, mobile phone B, mobile phone C, mobile phone D and mobile phone E.
Step S103, the mobile phone A updates a group registration configuration table, adds information of member mobile phones newly entering a group, and sets temporary permission of the new member mobile phones as a client;
step S104, establishing connection between the mobile phone A and the group members (mobile phone B, mobile phone C, mobile phone D and mobile phone E);
step S105, the mobile phone A sends a group registration configuration table to group members (mobile phone B, mobile phone C, mobile phone D and mobile phone E);
step S106, the mobile phone A updates the group registration configuration file according to the condition that the mobile phones of other group members receive the group registration configuration file;
step S107, the mobile phone A sends the updated group registration configuration file to other mobile phones of group members;
step S108, the mobile phones of other group members receive the updated group registration configuration file to synchronize the group registration configuration file stored locally, and the group completes the addition of new members.
The mobile phone currently needing to invite other mobile phones to enter the group can be a group owner or other group member mobile phones authorized by the group owner.
