Description

Multimedia broadcast multicast service acquisition method, device and communication system

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a communication system for acquiring a multimedia broadcast multicast service. Background technique

In the existing mobile communication system, Multimedia Broadcast Multicast Service (MBMS) technology is widely used for transmission of various multimedia broadcast multicast services, such as video program playback. Group communication can also be implemented using MBMS technology. In group communication, all users (UE, User Equipment) in a group form a group, and each group member can become the sender or receiver of the service. When a group member in a group initiates communication, the group member is the initiator of the group service, and the group service data can be sent to all group members in the group in MBMS mode. The service can be regarded as an MBMS service, and all group members can be As a user interested in the MBMS service, the control site of the group service is a Group Communication System Enabler Application Server (GCSE AS).

In general, mobile terminal users can obtain MBMS services through two transmission methods: broadcast multicast mode and unicast mode.

The broadcast multicast mode is implemented by a Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) technology. In the MBSFN system, multiple cells in a specific area simultaneously transmit MBMS service data of the same content, and the mobile terminal simultaneously performs MBMS transmission of multiple cells in the MBSFN network for joint reception. The MBMS service transmission path of the broadcast multicast mode is as shown in FIG. 1. The MBMS gateway (MBMS GW, MBMS Gateway) delivers the MBMS service to the relevant eNBs in the area through the MBMS bearer; the eNB delivers the MBMS service to all UEs or part of the UEs in the cell by means of broadcast multicast. On the air interface, a Multicast Control Channel (MCCH) is used to carry MBMS control signaling, and a Multicast Traffic Channel (MTCH) is used to carry MBMS service data. The UEs that are interested in the MBMS service can receive the MBMS service in three steps. First, the UE first learns the MCCH transmission information, such as the scheduling resource, the modulation and coding mode, and the MCCH modification period, by using the information in the system broadcast message. Second, the user receives the transmission on the MCCH. Control signaling, the control signaling includes a PMCH (Physical Multicast Channel) configuration, which may indicate an MBMS service identifier, a time domain resource and a radio configuration of the MBMS service scheduling, etc. Finally, the UE receives the MBMS service through the MTCH on the indicated resource. data.

The unicast mode receives the MBMS service data through the existing Evolved Packet System (EPS) bearer, as shown in FIG. 2, by establishing the UE and the packet data network gateway (P-GW, PDN-GW, Packet Data Network). The EPS bearer between the Gateway or the Serving Gate Way (S-GW) sends the MBMS service to a designated UE. For example, when the UE wants to receive an MBMS service and the current serving cell does not provide broadcast multicast transmission of the MBMS service, the UE initiates a service request to the network side through non-access stratum (NAS, Non-Access Stratum) signaling. Establish related EPS bearers. The MBMS service will be sent to the UE through the established EPS bearer.

In order to improve the transmission efficiency of the MBMS service, the MBMS service is transmitted in the prior art by using the transmission method shown in FIG. The transmission mode can be regarded as a combination of the above broadcast multicast mode and the unicast mode. In this transmission mode, the eNB in the MBSFN network receives the MBMS service through the interface with the MBMS GW, and further, the eNB can decide whether to transmit the MBMS service in the broadcast multicast mode or the unicast mode on the air interface. For example, in order to improve resource utilization efficiency, when the number of UEs interested in one MBMS service in the cell is relatively large, the eNB transmits the MBMS service by using the broadcast multicast mode; when the number of UEs interested in the MBMS service in the cell is small, the eNB adopts The unicast mode sends MBMS services to each UE on the air interface. This way can be called a hybrid approach.

It should be noted that the above description of the technical background is only for the purpose of facilitating the clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these solutions are set forth in the background section of the present invention. Summary of the invention

It can be seen from the background that in the prior art, the UE can receive the MBMS service through three transmission modes. In the broadcast multicast mode, all UEs interested in the MBMS service can receive the MBMS service broadcast by the cell through the MCCH/MTCH. In the unicast mode, the UE interested in the MBMS service can use the NAS signaling to the core network side entity. The MBMS service receiving request is initiated, and the MBMS service is received by the EPS bearer. In the hybrid mode, the eNB in the MBSFN network sends the MBMS service in an unicast manner on the air interface, and the UE interested in the MBMS service passes the air interface signaling ( For example, radio resource control signaling) is initiated to the eNB The MBMS service receives the request and receives the MBMS service through the radio bearer.

As can be seen from the above, when the eNB adopts the broadcast multicast mode, the eNB broadcasts the MBMS related information by using the system information and the MCCH signaling, and the UE can learn that the eNB currently uses the broadcast multicast transmission mode to transmit the MBMS service; and when the eNB adopts another transmission mode. The eNB does not send any MBMS service related information through the Uu interface (the interface between the User Equipment (UE) and the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The problem is that the UE that is interested in the MBMS service cannot know whether the transmission mode of the MBMS service in the current eNB is a unicast mode or a hybrid mode, and thus cannot determine which way to request to acquire the MBMS service.

In another embodiment of this embodiment, the transmission mode indication information is included in an information element of Multimedia Control Channel (MCCH) signaling.

In the present embodiment, the transmission mode of the MBMS is indicated by an implicit method. Currently, the information element of the MCCH signaling, for example, the Physical Multicast CHannel (PMCH) configuration information element includes the MBMS identifier, but also includes the scheduling information corresponding to the MBMS. In this embodiment, the MBMS is removed. The corresponding scheduling information, for example, the scheduling information corresponding to the MBMS is set to OPTIONAL to implicitly indicate that the transmission mode of the MBMS is a hybrid transmission mode.

The MBMS transmission mode is used to initiate a corresponding MBMS request process, thereby achieving the purpose of improving resource utilization.

Example 4

The embodiment of the present invention further provides a method for acquiring a multimedia broadcast multicast service, which is a process of the UE side corresponding to the method of the first embodiment, and the same content as that of the embodiment 1 is not repeatedly described. Figure 7 is a flow chart of the method. Referring to Figure 7, the method includes:

Step 701: The user equipment receives the transmission mode indication information sent by the base station.

The base station may send the foregoing transmission mode indication information to the UE in a broadcast or multicast manner to indicate the transmission mode of the MBMS used by the current cell of the UE. The contents of the transmission mode indication information and the bearer mode have been described in detail in Embodiment 1, and the content thereof is incorporated herein, and details are not described herein again.

Step 702: The user equipment determines, according to the transmission mode indication information, a transmission mode of the MBMS. The UE may determine a transmission mode of the MBMS of the current cell by using the transmission mode indication information. For example, if the transmission mode indication information is included in a system message or included in a message of Multimedia Control Channel (MCCH) signaling, and the transmission mode indication information includes an MBMS service identifier or includes an MBMS service identifier and a transmission mode indicator. And the transmission mode indicator indicates a hybrid transmission mode, and the user equipment determines that the transmission mode of the MBMS is a hybrid transmission mode; instead, if the transmission mode indication information is included in the system message or included in the multimedia control channel (MCCH) signaling In the message, but the transmission mode indication information does not include the MBMS service identifier or includes the MBMS service identifier and the transmission mode indicator, but the transmission mode indicator indicates the unicast transmission mode, the user equipment determines that the MBMS transmission mode is Unicast transmission method.

For another example, if the transmission mode indication information is included in a PMCH configuration information element of the Multimedia Control Channel (MCCH) signaling, and the transmission mode indication information includes an MBMS service identifier, and the scheduling information corresponding to the MBMS service is not included, The user equipment determines that the transmission mode of the MBMS is a hybrid transmission mode; instead, if the transmission mode indication information includes the PMCH configuration information of the Multimedia Control Channel (MCCH) signaling In the element, but the transmission mode indication information includes both the MBMS service identifier and the scheduling information corresponding to the MBMS service, the user equipment determines that the transmission mode of the MBMS is a broadcast multicast transmission mode.

Step 703: The user equipment acquires a multimedia broadcast multicast service according to the determined transmission mode of the MBMS.

After determining the transmission mode of the MBMS, the UE may initiate a corresponding MBMS request procedure to obtain the MBMS.

For example, if it is confirmed that the transmission mode of the MBMS is a hybrid mode, the UE may initiate an MBMS transmission request to the eNB, and the eNB learns that the UE is interested in the MBMS service according to the request of the UE, and the eNB sends relevant configuration information to the UE and starts to the UE. Send MBMS service data. In addition, if the UE is in an idle state before sending an MBMS service request to the eNB, the UE is further changed from the idle state to the connected state before the process.

For example, if it is confirmed that the transmission mode of the MBMS is the unicast mode, the UE may send an MBMS transmission request message to the core network side entity, establish a corresponding EPS bearer, and receive the MBMS data from the EPS bearer. Similarly, if the UE is in an idle state before initiating an MBMS request to the core network, the UE is further changed from the idle state to the connected state before the process.

For another example, if it is confirmed that the transmission mode of the MBMS service is the broadcast multicast mode, the UE receives the configuration information of the MTCH, and receives the MBMS data in the allocated MBSFN subframe through the MTCH.

FIG. 8 is a schematic diagram of an interaction process between a UE and a network side entity. As shown in FIG. 8, the interaction process includes the following steps:

Step 801: The eNB sends the transmission mode indication information to the UE in a broadcast or multicast manner to indicate the MBMS service transmission mode used by the current cell.

The content and the bearer mode of the transmission mode indication information are as described above, and are not described here.

Step 802: The UE determines, according to the transmission mode indication information in step 801, the transmission mode of the MBMS used by the current cell.

If the transmission mode of the MBMS used by the current cell is determined to be a hybrid mode, the steps are performed.

803a. If it is determined that the transmission mode of the MBMS used by the current cell is the unicast mode, step 803b is performed. If it is determined that the MBMS transmission mode used by the current cell is the broadcast multicast mode, step 803c is performed.
