Description

A multicast service transmission device and method

technical field

The present invention relates to the field of wireless communication, in particular to a multicast service transmission device and method.

Background technique

The multicast technology is a point-to-multipoint data transmission technology. Specifically, the multicast technology means that a data sending device sends the same data to multiple data receiving devices through the same shared channel.

At present, the Multicast technology used in the 3rd Generation Partnership Project (English: 3rd Generation Partnership Project, referred to as: 3GPP) includes Multimedia Broadcast Multicast Service (English: Multimedia Broadcast Multicast Services, referred to as: MBMS) and single cell point-to-multipoint (English: single cell point to multipoint, referred to as: SC-PTM) technology. Taking the use of multicast technology to transmit multimedia broadcast multicast services as an example, the base station transmits to multiple user equipments (English: User Equipment, referred to as UE) in the cell through a physical multicast channel (English: Physical Multicast Channel, abbreviated: PMCH) simultaneously. MBMS, so that multiple UEs obtain MBMS by reading PMCH at the same time.

As shown in Figure 1, the UE is receiving the multicast service A sent by cell 1 through the multicast bearer. When the UE switches from cell 1 to cell 2 that does not send multicast service A, the UE determines by reading the broadcast message of cell 2 After the cell 2 does not send the multicast service A, it establishes a unicast bearer with the cell 2 first, so as to continue to receive the multicast service A through the unicast bearer. In the process of handing over to cell 2 first and then establishing a unicast bearer, service interruption occurs when the UE receives the multicast service A. In order to avoid service interruption, as shown in Figure 2, when the UE moves from cell 1 to cell 2, the UE first establishes a unicast bearer with cell 1 to continue receiving multicast services sent by cell 1 through the unicast bearer A, and then switch from cell 1 to cell 2. However, by adopting this technical solution, because the cell 1 schedules the UE to receive the data packets of the multicast service A through the multicast bearer and the establishment of the unicast bearer respectively, resources are wasted.

Embodiment five

Embodiment five is corresponding to embodiment one,

As shown in Figure 16, an embodiment of the present invention provides a multicast service transmission method, the method is executed by a base station, including:

S1601: The base station establishes a unicast bearer with the user equipment UE;

S1602: The base station determines that the established unicast bearer is used to transmit the multicast service received by the UE;

S1603: When the base station determines that the current cell where the UE is located is using the multicast bearer to transmit the multicast service, schedule the multicast bearer to transmit the data packet of the multicast service, so that the UE receives the data packet of the multicast service on the multicast bearer, and The UE is not scheduled to receive data packets of the multicast service on the unicast bearer.

In this embodiment, establishing a unicast bearer with the UE by the base station can avoid the interruption of the multicast service transmitted by the base station to the UE when the UE is handed over from the current cell to the target cell.

In this embodiment, after the base station establishes a unicast bearer with the UE, when the data packet of the multicast service associated with the unicast bearer arrives at the base station, if the base station does not schedule the UE to receive the data packet of the multicast service on the unicast bearer, the It will occupy unicast bearer resources to achieve the purpose of saving resources. This avoids resource waste caused by the base station scheduling other UEs to receive multicast services on multicast bearers and scheduling the current UE to receive multicast services on unicast bearers in the prior art.

In this embodiment, when determining that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service, the base station schedules the UE to receive the data packet of the multicast service on the unicast bearer.

Optionally, the base station may determine that the current cell where the UE is located does not use a multicast bearer to transmit the multicast service by the following method:

Method 1. When the base station receives a notification message of stopping the multicast service sent by the server controlling the multicast service, it determines that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service.

Method 2. When the base station determines that the number of UEs receiving the multicast service in the current cell is less than a preset value, determine that the current cell where the UE is located does not use a multicast bearer to transmit the multicast service.

In this embodiment, the base station may determine that the UE is in the edge area of the current cell when receiving the unicast bearer establishment request sent by the core network device, and the unicast bearer establishment request is used to request the base station to establish a unicast bearer with the UE, The core network device sending the unicast bearer establishment request to the base station is triggered by the UE sending the unicast bearer establishment request to the core network device through the application server.

Optionally, before establishing a unicast bearer with the UE, the base station may send a unicast bearer establishment threshold to the UE, so that when the UE determines that a unicast bearer needs to be established according to the received unicast bearer establishment threshold, the base station is triggered to establish a unicast bearer with the UE. Unicast bearer. Specifically, the base station sends the unicast bearer establishment threshold to the UE, and the UE determines the unicast bearer establishment index of the current cell, and when the unicast bearer establishment index is less than or equal to the unicast bearer establishment threshold, it can determine that it is in the edge area of the current cell . At this time, the UE sends a unicast bearer establishment request to the core network device through the application server, so as to trigger the core network device to request the base station to establish a unicast bearer with the UE. Optionally, the base station sends the unicast bearer establishment threshold to the UE through a broadcast message or a dedicated message, where the dedicated message includes a unicast bearer reconfiguration message, but is not limited thereto.

Taking the threshold of signal strength as the threshold of unicast bearer establishment as an example, since the signal strength decreases with the increase of the distance between the current geographic location and the center of the cell, when the UE is in the edge area of the cell, the signal strength is weak. Therefore, the UE can determine whether the UE is in the edge area of the current cell by detecting the signal strength of the current geographic location and comparing the signal strength of the current geographic location with the signal strength threshold, and then determine whether the UE is in the edge area of the current cell. The base station needs to be triggered to establish a unicast bearer with the UE.

S2105: The core network device sends a unicast bearer establishment request to the base station, and the unicast bearer establishment request carries second indication information;

S2106: The base station establishes a unicast bearer with the UE;

S2107: The base station sends a unicast bearer reconfiguration message to the UE;

S2108: When the base station determines that the current cell where the UE is located is using the multicast bearer to transmit the multicast service, schedule the multicast bearer to transmit the data packet of the multicast service, so that the UE receives the data packet of the multicast service on the multicast bearer without Scheduling the UE to receive data packets of the multicast service on the unicast bearer; or

When determining that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service, the base station schedules the UE to receive data packets of the multicast service on the unicast bearer.

Optionally, S2109: When the UE determines that receiving any data packet of the multicast service fails, send a data packet reception failure indication message to the base station, and the indication message is used to indicate that the UE fails to receive any data packet;

S2110: the base station schedules the UE to receive any data packet and the sequence indication information of any data packet on the unicast bearer;

Wherein, the sequence indication information is used to indicate the sequence position of any data packet in the multicast service. Optionally, the sequence indication information may be the time when the base station first transmits any data packet to the UE, or the time when the UE confirms that the reception of any data packet fails, but is not limited thereto.

Through the technical solution in Embodiment 5, when the base station transmits the multicast service to the UE, the base station learns the relationship between the UE's unicast bearer and the multicast service, and the base station can choose whether to schedule according to the way the current cell transmits the multicast service The unicast bearer transmits the multicast service to the UE, that is, when the base station determines that the current cell where the UE is located is using the multicast bearer to transmit the multicast service, it schedules the multicast bearer to transmit the data packet of the multicast service, so that the UE can transmit the multicast service on the multicast bearer. Receive data packets of multicast services without scheduling the UE to receive data packets of multicast services on unicast bearers, avoiding the problem of simultaneous scheduling of multicast bearers and unicast bearers by the base station in the process of transmitting multicast services using existing technical solutions The resulting waste of bearer resources can improve the utilization rate of bearer resources for transmitting multicast services through the technical solution in this embodiment.

Therefore, the UE can determine whether the UE is in the edge area of the current cell by detecting the signal strength of the current geographic location and comparing the signal strength of the current geographic location with the signal strength threshold, and then determine whether the UE is in the edge area of the current cell. The base station needs to be triggered to establish a unicast bearer with the UE.
