Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1 shows an application scenario of a group priority notification method in group communication according to an embodiment of the present invention, where the application scenario may include: a plurality of communication groups, base stations, evolved packet core (English: evolved packet core, abbreviation: EPC) network devices, and application servers; in the application scenario, one base station can cover a plurality of communication groups, that is, one base station can schedule communication resources for a plurality of groups at the same time; each communication group may contain a plurality of user equipments UE, which may be cellular phones, pagers, personal digital assistants (english: personal digital assistant, abbreviated: PDA), laptop computers, or other handheld, stationary or portable communication devices supporting push to talk (abbreviated: PTT) communications; the EPC network device may be a short-range service function entity (english: proximity service function, abbreviated: proSe function), a home subscription server (english: home subscriber server, abbreviated: HSS), and a policy and charging rule function unit (english: policy and changing rules function, abbreviated: PCRF); the application server may be a device used internally by an industry or department for determining group priority during group communication; preferably, the application server may be in a mission critical intercom communication (English: mission critical push to talk, abbreviation: MCPTT) system (e.g., police department, fire department).

It should be noted that, after receiving the group priority of the group sent by the application server, the EPC network device in the application scenario shown in fig. 1 does not directly notify the base station of the group priority, but sends the group priority to the base station through some other device (this part is not shown in fig. 1); for example, as shown in fig. 1A, when the EPC device is ProSe function, proSe function passes through HSS and mobility management entity (english: moblity management entity, abbreviation: MME); or the UE informs the base station of the group priority; as shown in fig. 1B, when the EPC network device is an HSS, the HSS notifies the base station of the group priority through the MME; as shown in fig. 1C, when the EPC network device is a PCRF, the PCRF informs the base station of the group priority through a packet data network gateway (english: packet data network gateway, abbreviated: PGW) and MME.

The group priority notification method in group communication provided by the invention is respectively executed for each device by the first embodiment, the second embodiment, the third embodiment and the fourth embodiment.

Example 1

Fig. 2 shows a flowchart of a communication method of group priority in group communication, which is applied to ProSe function and provided in an embodiment of the present invention, where the method may include:

201. The ProSe Function receives a first message sent by an application server; the first message includes: a first user identification of a user equipment, a first group identification of a group in which the user equipment is located, and a group priority of the group.

Wherein, the first user identifier is used for identifying the user equipment, and may be: an external identifier defined by the third generation partnership project (english: 3rd generation partnership project, abbreviation: 3 GPP), such as: the mobile subscriber number (English: mobile Subscriber International ISDN/PSTN number, abbreviation: MSISDN), ISDN, integrated service digital network, public switched telephone network, public switched telephone network.

The group may be any one of a plurality of groups subscribed to by the user equipment; the user equipment may be an initiator of group communication in the group; the first group identifier may be an application layer group identifier for identifying a group name of the group in an industry or a department; for example, a user in a fire department simultaneously signs up with group 1 (emergency group), group 2 (lead group), group 3 (service group), etc., the first group is identified as fire department-group 3 when the group is the service group.

The group priority can be dynamically determined by the application server according to the current attribute of the group, an attribute value corresponding to the current attribute and a preset priority ranking relation, and is used for representing the level of the group in a communication system so as to ensure that the determined group priority accords with the requirement of group communication; typically, group priorities can be categorized into high, medium, and low levels.

Wherein the current attribute comprises a static attribute and/or a dynamic attribute; the static attribute is an inherent attribute of the group and does not change along with the change of the group, including but not limited to one or more of the type of the group, the running time of the group and the default minimum priority of the group;

the dynamic attribute is an attribute that varies as a function of what happens within a group, including but not limited to one or more of the type of event that happens within the group, the severity of the event.

Preferably, the ProSe Function may receive the first message sent by the application server through the PC2 interface.

202. The ProSe Function sends a notification message to the base station according to the received first message; the notification message includes: a second user identification of the user equipment, a second group identification of the group, and a group priority of the group.

Wherein the second user identifier is also used for identifying the user equipment, and may be an internal identifier defined by the 3GPP system, for example: international mobile subscriber identity (english: international mobile subscriber identification number, abbreviation: IMSI).

The second group identification may be a network layer group address such as: layer 2 (Layer 2) address for identifying a destination address of the user equipment for group communication. Preferably, before step 202, the ProSe Function may select, according to the first group identifier, any group address from group addresses stored in the ProSe Function as a second group identifier of the group, and establish a correspondence between the second group identifier and a group priority of the group.

For example, in this embodiment, the sending, by the ProSe Function, a notification message to the base station may include:

the ProSe Function firstly sends the notification message to a home subscription server (English: home subscriber server, abbreviated: HSS) through a PC4a interface, the HSS sends the notification message to an MME through an S6a interface, and then the MME sends the notification message to the base station through an S1 interface;

or the ProSe Function firstly sends the notification message to an MME through a PCx interface, and then the MME sends the notification message to the base station through an S1 interface.

It should be noted that, in the notification message forwarded by the HSS to the MME and the notification message forwarded by the MME to the base station, some other information besides the second user identifier of the user equipment, the second group identifier of the group, and the group priority of the group may be added, which is not limited in the embodiment of the present invention, but in the forwarding process, the notification message must include the group priority of the group, so as to ensure that the base station can receive the group priority of the group.

Specifically, in the embodiment of the present invention, the ProSe Function may passively directly receive the first message sent by the application server, but as a more general implementation manner, before step 201, the ProSe Function may also send a message for indicating that the application server sends a group priority to the ProSe Function to the application server, and then receive the first message sent by the application server, which is specifically implemented as follows:

the ProSe Function sends a third message to the application server according to the application identifier, and the application server sends the first message to the ProSe Function after determining the group priority of the group; the third message includes a first user identification of the user device, a first group identification of the group.

Wherein the application identifier is used for identifying the application server.

Preferably, in the embodiment of the present invention, the second message received by the ProSe Function and the third message sent to the application server may further include: the current attribute of the group and the attribute value corresponding to the current attribute are used for facilitating the application server to determine the group priority of the group according to the current attribute of the group and the attribute value corresponding to the current attribute.

Furthermore, after the ProSe Function receives the second message sent by the user equipment, the method further includes: and authenticating the validity of the user equipment between the ProSe Function and the HSS, and performing authorization check on group communication initiated by the user equipment.

Further, in an embodiment of the present invention, the method may further include:

and the ProSe Function sends a second group identifier of the group to the application server so that the application server establishes a corresponding relation between the second identifier and the group priority of the group according to the second identifier, and sends the corresponding relation to the base station directly through user equipment.
