Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a short message sending method and a base station of a broadband cluster.
Background
A Long Term Evolution (LTE) broadband cluster is a broadband wireless communication system that supports broadband data transmission service, voice and multimedia-form cluster command and scheduling service based on LTE technology.
In an LTE broadband cluster, an enhanced mobile management entity (eMMC) sends a short message of a user plane to a base station, the base station establishes a group based on the short message sent by the eMMC, and sends a paging message of the group to member terminals of the group through an air interface after resources are allocated to the group, so that the member terminals of the group monitor the short message sent by the base station according to the paging message of the group.
However, in the existing LTE broadband cluster, the process of sending the short message by the base station and the process of sending the paging message by the base station are two independent processes, and the process of sending the paging message by the base station in the LTE broadband cluster follows the power saving policy of discontinuous reception DRX, that is, the base station sends the paging message according to a predetermined sending cycle, and during this cycle, the base station may have sent the short message to the member terminals of the group, but since the member terminals of the group do not receive the paging message about the group, the terminal cannot parse the received short message, thereby causing the problem of data loss.
Disclosure of Invention

A first aspect of the embodiments of the present invention provides a method for sending a short message in a broadband cluster, where the method includes:
when receiving a short message sent by an enhanced mobile management entity (eNME), a base station establishes a group and allocates frequency resources for the group;
and the base station repeatedly sends the short message by adopting the frequency resource.
A second aspect of an embodiment of the present invention provides a base station, including:
the system comprises a group establishing module, a frequency resource allocating module and a processing module, wherein the group establishing module is used for establishing a group and allocating the frequency resource to the group when a base station receives a short message sent by an enhanced mobile management entity (eNME);
and the sending module is used for repeatedly sending the short message by adopting the frequency resource.
In the embodiment of the invention, when the short message sent by the enhanced mobile management entity is received, the group is established, the frequency resource is distributed to the group, and the short message of the group is repeatedly sent by adopting the frequency resource, so that even if the short message is sent to the member terminals of the group before the paging message of the group, the member terminals can monitor and receive the short message repeatedly sent by the base station according to the subsequently received paging message, thereby avoiding the problem of short message loss and improving the reliability of short message sending in the broadband cluster.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover non-exclusive inclusions, e.g., a process or an apparatus that comprises a list of steps is not necessarily limited to those structures or steps expressly listed but may include other steps or structures not expressly listed or inherent to such process or apparatus.
In the existing broadband cluster, the sending of the paging message and the short message of the group is two independent sending processes. When a base station receives a short message sent by an enhanced mobile management entity (eMMC), the base station establishes a group and allocates frequency resources for the group, and then, on one hand, the base station follows a power saving strategy of Discontinuous Reception (DRX) and sends a paging message for indicating member terminals of the group to monitor and receive the short message of the group when the next sending period arrives according to a preset sending period, and on the other hand, the base station directly sends the received short message to the member terminals of the group according to the frequency resources allocated for the group. Therefore, the situation that the short message is sent first without sending the paging message is caused, so that the problem that the member terminal cannot normally monitor and receive the short message is caused, and the short message is lost.
In order to solve the above problem, in order to improve the transmission reliability of the short message in the broadband cluster, an embodiment of the present invention provides a short message sending method for the broadband cluster, where the method is executed by a base station. Referring to fig. 1, fig. 1 is a flowchart of a method for sending a short message in a broadband cluster according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
In an actual scenario, when receiving a short message sent by an enhanced mobile management entity eMME, a base station establishes a group and allocates a frequency resource for the group, where the frequency resource is used for transmitting the short message of the group.
Further, after successfully establishing the group and allocating the frequency resource to the group, the base station generates a paging message for instructing the member terminals of the group to monitor and receive the short message of the group, wherein the paging message includes, but is not limited to, the group identifier and the information of the allocated frequency resource.
In this embodiment, the group establishing method and the paging message generating method are similar to those in the prior art, and are not described herein again.
And step 102, the base station repeatedly sends the short message by adopting the frequency resource.
Optionally, in this embodiment, the sending of the paging message of the group follows the DRX power saving policy, and the sending period may be set according to needs, which is not specifically limited in this embodiment.
Optionally, in order to facilitate the member terminal of the group to identify and clean the repeatedly received short message, in this embodiment, the base station uses the frequency resource of the group and repeatedly sends the short message of the group with the same serial number, that is, for the repeatedly sent short message, the same serial number is carried each time the short message is repeatedly sent, and the member terminal identifies the repeated data according to the serial number carried in the received short message.
Therefore, when the group short message is sent to the member terminals of the group before the group paging message, the member terminals do not receive the paging message, so that the group short message cannot be monitored and received accurately.
Optionally, in this embodiment, the base station may repeatedly send the group short message in the following manner:
in a possible implementation manner, the base station repeatedly sends the short messages of the group by using the frequency resources allocated to the group by the base station until the preset number of times is reached.
In another possible implementation manner, the base station repeatedly sends the short message of the group at a preset period by using the frequency resource allocated to the group by the base station until receiving the target response message, where the target response message is used to indicate that the member terminals of the group successfully receive the short message of the group.
In this manner, the preset period may be preferably embodied as a period in which the base station transmits the paging message.
In another possible implementation manner, the base station repeatedly transmits the short messages of the group within a preset time length range by using the frequency resources allocated to the group by the base station. For example, if the preset time length range is 20ms, the base station repeatedly sends the short message of the group within 20ms after allocating the frequency resource to the group. It is understood that this is by way of illustration and not by way of limitation.
In this embodiment, when receiving a short message sent by an enhanced mobility management entity, a group is established, a frequency resource is allocated to the group, and the short message of the group is repeatedly sent by using the frequency resource, so that even if the short message is sent to a member terminal of the group before a paging message of the group, the member terminal can monitor and receive the short message repeatedly sent by a base station according to a subsequently received paging message, thereby avoiding the problem of short message loss and improving the reliability of sending the short message in a broadband cluster.
