when a multicast single frequency network (MBSFN) group is established, determining a target Service Area (SA) where a member terminal of the MBSFN group is located;
when the MBSFN group is successfully established, according to the corresponding relation between a pre-established signaling multicast channel and an SA, the paging message of the MBSFN group is broadcasted in the target SA through the signaling multicast channel corresponding to the target SA, wherein the corresponding relation comprises a plurality of signaling multicast channels, and the paging message is used for indicating the member terminal of the MBSFN group to monitor and receive the data of the MBSFN group.
A second aspect of the present invention provides an apparatus for transmitting MBSFN group signaling, including:
the system comprises a determining module, a judging module and a judging module, wherein the determining module is used for determining a target service area SA where member terminals of a multicast single frequency network (MBSFN) group are located when the MBSFN group is established;
and the first broadcasting module is used for broadcasting a paging message of the MBSFN group in the target SA through a signaling multicast channel corresponding to the target SA according to a corresponding relation between a pre-established signaling multicast channel and the SA when the MBSFN group is successfully established, wherein the corresponding relation comprises a plurality of signaling multicast channels, and the paging message is used for indicating a member terminal of the MBSFN group to monitor and receive data of the MBSFN group.

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.
The embodiment of the invention provides an MBSFN group signaling sending method, which can be executed by an MBSFN group signaling sending device, and the device can be arranged in a group service server but is not limited to be arranged in the group service server. Referring to fig. 1, fig. 1 is a flowchart of a MBSFN group signaling sending method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
In this embodiment, when a terminal moves from one SA to another SA, the terminal reports the location, that is, the SA where the terminal is located, to a group service server, and after receiving the SA reported by the terminal, the group service server matches the SA with the locally stored SA where the terminal is located, and if the SA is not consistent, the locally stored SA of the terminal is updated to the SA reported by the terminal, and if the SA is consistent, the SA is not updated. Optionally, when the MBSFN group is established, the MBSFN group signaling sending apparatus searches the terminal identifier corresponding to the group identifier in the local database according to the received group identifier, and determines the SA (i.e. target SA) where the member terminal of the MBSFN group is located according to the correspondence between the locally stored terminal identifier and the SA in the service area.
102, when the MBSFN group is successfully established, according to a correspondence between a pre-established signaling multicast channel and an SA, broadcasting a paging message of the MBSFN group in the target SA through the signaling multicast channel corresponding to the target SA, wherein the correspondence includes a plurality of signaling multicast channels, and the paging message is used for instructing a member terminal of the MBSFN group to monitor and receive data of the MBSFN group.
Optionally, in a possible implementation manner, the correspondence between the signaling multicast channel and the SAs may be generated after the MBSFN group signaling sending apparatus randomly allocates one or more signaling multicast channels to each SA in the network, for example, there are a signaling multicast channel a, a signaling multicast channel b, and a signaling multicast channel c currently, and the current network includes service areas SA1, SA2, and SA3, and then the correspondence between the signaling multicast channel and the SA that are randomly established may be: the signaling multicast channel a corresponds to SA1, the signaling multicast channel b corresponds to SA2, and the signaling multicast channel c corresponds to SA3, but in an actual scenario, the signaling multicast channel a may be randomly configured to have other corresponding relationships besides the above corresponding relationships, which is only an example and is not a unique limitation to the present invention.
Optionally, in another possible implementation manner, the corresponding relationship between the signaling multicast channel and the SAs may be established by the MBSFN group signaling sending apparatus according to the service type of each SA and/or the load information of each SA in the network. For example, service areas with the same service type are configured to correspond to a same signaling multicast channel, or SAs with the same load number in a preset range are configured to correspond to a signaling multicast channel, or SAs with the same service type and the same load number in the preset range are configured to correspond to a signaling multicast channel. It is understood that this is by way of illustration and not by way of limitation.
Optionally, when the terminal receives multiple paging messages of the MBSFN group from the signaling multicast channel corresponding to the SA where the terminal is located, the terminal selects the paging message bound to the SA where the terminal is located from the multiple paging messages, and sends the paging message to the modem, so that the modem starts to monitor the data of the MBSFN group. Particularly, if the SA where the terminal is located has a plurality of multicast traffic channels available for reception corresponding to the MBSFN group, the multicast traffic channels are received together and decoded through a preset voice format. If the modem can not obtain the configuration of the multicast service channel according to the paging message, the unicast reception is triggered by the real-time transport protocol RTP voice quality detection.
In this embodiment, when the MBSFN group is established, the target service area SA in which the member terminals of the MBSFN group are located is determined, and when the MBSFN group is successfully established, the paging message of the MBSFN group is broadcasted in the target SA through the signaling multicast channel corresponding to the target SA according to the correspondence between the plurality of signaling multicast channels and the SAs which are established in advance. In this embodiment, the corresponding relationship between the multiple signaling multicast channels and the SAs is pre-established, so that the paging message of the MBSFN group does not need to be broadcasted in the whole network as in the prior art, but the paging message is broadcasted in the SA area where the member terminals of the MBSFN group are located according to the corresponding relationship between the signaling multicast channels and the SAs, thereby reducing the waste of the signaling multicast channels on the multicast resources, and the terminal only receives the message of the signaling multicast channel corresponding to the cell where the terminal is located, so the terminal does not receive the establishment or release message from all MBSFN groups in the whole network, thereby reducing the power consumption of the terminal.
Fig. 2 is a flowchart of an MBSFN group signaling sending method according to another embodiment of the present invention, as shown in fig. 2, on the basis of the embodiment of fig. 1, the method includes:
Optionally, in this embodiment, the signaling multicast channel corresponding to each SA may be randomly allocated to each SA by the MBSFN group signaling sending apparatus, or may be established by the MBSFN group signaling sending apparatus according to the service type of each SA and/or the load information of each SA in the network, for example, service areas with the same service type are configured to correspond to one same signaling multicast channel, or SAs with the same load number in the same preset range are configured to correspond to one signaling multicast channel, or SAs with the same service type and the same load number in the same preset range are configured to correspond to one signaling multicast channel. It is understood that this is by way of illustration and not by way of limitation.
Optionally, in an actual scenario, the correspondence between the signaling multicast channel and the SA is not limited to include the correspondence between the signaling multicast channel and the SA, but may also include a quality of service classification identifier QCI of the signaling multicast channel, an IP address and port information of the signaling multicast channel, and the like.
Optionally, in this embodiment, the information of the signaling multicast channel corresponding to each SA is sent to the terminal under each SA in a one-to-one sending manner.
In this embodiment, when the MBSFN group is established, the target service area SA in which the member terminals of the MBSFN group are located is determined, and when the MBSFN group is successfully established, the paging message of the MBSFN group is broadcasted in the target SA through the signaling multicast channel corresponding to the target SA according to the correspondence between the plurality of signaling multicast channels and the SAs which are established in advance. In this embodiment, the corresponding relationship between the multiple signaling multicast channels and the SAs is pre-established, so that the paging message of the MBSFN group does not need to be broadcasted in the whole network as in the prior art, but the paging message is broadcasted in the SA area where the member terminals of the MBSFN group are located according to the corresponding relationship between the signaling multicast channels and the SAs, thereby reducing the waste of the signaling multicast channels on the multicast resources, and the terminal only receives the message of the signaling multicast channel corresponding to the cell where the terminal is located, so the terminal does not receive the establishment or release message from all MBSFN groups in the whole network, thereby reducing the power consumption of the terminal.
