Description

Business scheduling method, system and equipment for enhanced broadcast multicast service

【Technical Field】

This application relates to the field of communication technology, and in particular to a service scheduling method and system for an enhanced broadcast multicast service.

【Background technique】

E-MBMS (Enhanced Broadcast Multicast Service) supports the provision of multicast/broadcast networks in cellular systems. Each cell that joins and sends MBMS (Multimedia Broadcast/Multicast Service) service is configured with a point-to-multipoint radio resource, and all users registered for the MBMS service can receive the same transmission signal at the same time.

Two logical channels are defined in E-MBMS to support p-t-m (Point to Multi-point) delivery: MCCH (Multicast Control Channel) and MTCH (Multicast Service Channel).

By establishing E-MBMS bearers, multiple cells transmit the same information on the same time-frequency resources. Each terminal can receive this part of the information, and can use this to effectively use the signal power from multiple cells, thereby Significantly improve coverage. This multi-cell transmission, called MBSFN (Multimedia Broadcast Multicast Service Single Frequency Network) transmission, can not only increase the strength of the received signal, but also eliminate the interference of different signals between cells.

In order to support the MBSFN transmission mode, E-MBMS defines a new transmission channel MCH (multicast channel), which can not only achieve broadcast coverage of the entire cell, but also support simultaneous MBMS transmission among multiple cells .

When the base station delivers the session to the terminal, the terminal will perform multicast resource monitoring on the session to receive corresponding data.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art clearly and implicitly understand that the embodiments described herein can be combined with other embodiments.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of an embodiment of the enhanced broadcast multicast service system of the present application.

The system described in this embodiment includes a base station 10, a terminal 20, a multi-cell/multicast coordination entity (MCE) 30, and a core network 40. The core network 40 can be used to send MBMS data, and the MCE 30 can allocate multicast radio resources and issue multicast control signaling. The base station 10 can be used to transmit the session and deliver content to the terminal 20, and the terminal 20 receives the session transmitted by the base station 10, thereby realizing data reception.

The specific process may be that the core network 40 sends an MBMS session start request to the MCE 30 that controls the base station 10 in the target MBMS service area. MCE 30 confirms the MBMS session start request, MCE 30 sends the MBMS session start message to the base station 10 in the target MBMS service area, the base station 10 confirms the MBMS session start request, and sends the MBMS session start message to the terminal 20, and the base station 10 joins the IP address After the group is broadcast, the core network 40 transmits the session data to the base station 10, and the base station 10 then delivers the session data to the terminal 20.

The base station 10 can judge the status of the session sent to the terminal 20. After the base station 10 judges that the transmitted session has not been actually sent in the cell where the terminal 20 is located, the base station 10 will send the multicast In the channel scheduling information, a corresponding invalid indication is configured for a session that is not actually delivered, and the configured scheduling information of the multicast channel is sent to the terminal 20. When the terminal 20 receives the scheduling information of the multicast channel sent by the base station 10, if it detects that there is an invalid indication configured for a session, it will cancel the multicast resource monitoring for the session.

The base station 10 can also use the resources occupied by the sessions that are not actually delivered to schedule other services, such as non-multimedia broadcast/multicast services, or unicast services. The terminal 20 may also receive scheduling information of other services performed by the base station 10, so as to achieve the effect of data transmission with the base station 10.

Please refer to Fig. 2, which is a schematic flowchart of a first embodiment of a service scheduling method for an enhanced broadcast multicast service according to the present application. The first embodiment of the service scheduling method for the enhanced broadcast multicast service of this application may include the following steps:

S100: Determine whether the session is actually delivered in the cell.

When E-MBMS is used for multicast broadcast transmission, the base station sends MBMS data to the air interface, and then is received by the terminal to realize the transmission of MBMS data. When the base station needs to deliver the data of a certain session to the terminal, it needs to occupy certain air interface resources to send the data.

In a specific implementation scenario, in an area covered by a 4G network (fourth generation mobile communication technology), the base station determines whether the session is actually delivered in the cell. The cell is the area covered by the base station. For example, in an MBSFN transmission area, multiple cells simultaneously issue a certain session, that is, multiple base stations simultaneously issue the same session. For one of the base stations, there may be a situation in which one of the sessions of the base station is not actually delivered, but the other base stations actually deliver. For the base station, since the session that is not actually issued will not be released, the air interface resources of the base station will still be occupied. For example, when base station A is performing scheduling, its corresponding cell bears session 1, session 2, and session 3. Among them, base station A can detect whether the session carried by it is actually delivered while scheduling. When the base station detects that the session 2 is not actually delivered, it is equivalent to that the air interface resources occupied by the session 2 are not actually used, and there is a waste of resources, and other base stations send sessions normally, that is, other base stations’ Session 2 is the actual delivered state. Of course, in other implementation scenarios, there may be more than one session that is not actually issued.

When the base station detects that the session has actually been delivered in the cell, the base station will continue to deliver the session, so that the terminal continues to receive MBMS data.

Please refer to FIG. 3 in combination. FIG. 3 is a schematic diagram of the second process of the first embodiment of the service scheduling method provided by the present application.

For the base station to detect whether the session is actually delivered, for example, it can be implemented through the following steps S101-S102 included in step S100:

S101: Determine whether the session is received by the terminal in the cell, or whether the establishment of the session in the cell fails.

When the base station detects that there are users registered for the corresponding MBMS service in the cell covered by it, the base station starts to transmit MBMS data to the corresponding terminal.

In a specific implementation scenario, when the base station bears three sessions 1, session 2, and session 3, the base station will join the IP multicast group to receive MBMS data including sessions 1, 2, and 3 sent by the core network. After the base station receives the MBMS data, if it detects that the session 2 is in the cell and there is no user registered for the corresponding MBMS service, it is determined that the session 2 is not received by the terminal in the cell. For sessions 1 and 3, since these two sessions are received by the corresponding terminal, the sessions 1 and 3 are received by the terminal.

In another specific implementation scenario, when the base station carries 3 sessions 1, 2 and 3, the MCE will allocate the resources occupied by the PMCH (Physical Multicast Channel) used to transmit MBMS data. The MCE can request the start of a session to enable the base station to establish a corresponding interface to receive the MBMS data sent by the core network. During MBMS data transmission, if a certain session, for example, session 2 fails to be established, it is determined that the establishment of session 2 of the cell covered by the base station fails. Specifically, the reason for the failure to establish session 2 may be that the transmission channel used to transmit session 2 fails to be established, for example, the establishment of the PMCH fails. Of course, it is also possible that there is an error in the MBMS session start message sent by the MCE, causing the establishment of session 2 to fail. It is understandable that there are not only the above two reasons for the failure of session establishment, and the reasons may also exist in each process from establishment to transmission of the session.

When the base station determines that the session has been received by the terminal in the cell, or the session is successfully established in the cell, it is determined that the session has actually been delivered, and the base station will continue the operation of delivering the session.

S102: If it is not received by the terminal or the establishment fails, it is determined that it is not actually delivered in the cell.

In a specific implementation scenario, during MBMS data transmission, among the many sessions carried by the base station, if the base station detects one of the sessions, for example, session 2 does not have a corresponding terminal to receive the data of the session, then it is determined that session 2 is not available. It is actually issued in the cell covered by the base station. If other sessions are received by the terminal, it is determined that the corresponding session has actually been issued.

In another specific implementation scenario, if a session fails to be established, whether it is because the transmission channel establishment fails, such as PMCH establishment failure, or other reasons, as long as the session cannot transmit data, it is determined that the session is not in Actually issued by the cell where it is located. When the session is successfully established, the base station determines that the session has actually been issued in the cell covered by it, and continues the operation of issuing the session.

Continue to refer to Figure 2, S200: If it is not actually delivered in the cell, configure a corresponding invalid indication for the session in the scheduling information of the multicast channel.

When the base station detects that there is a session that has not been actually delivered among the sessions it bears, the base station can configure a corresponding invalid indication for the session that has not been actually delivered in the scheduling information of the multicast channel sent by the base station. The number of sessions that are not actually delivered can be one or multiple.

In a specific implementation scenario, in an E-UTRAN network composed of multiple base stations, the MAC entity of the base station can map logical channels to transmission channels, specifically MCCH (multicast control channel) and MTCH (multicast control channel). Traffic channel) is mapped to MCH (multicast channel). At this time, the base station can use the MCH to communicate with the terminal. At the same time, at the beginning of each MSP (MCH scheduling period), the base station will send the scheduling information of the multicast channel to the terminal. The scheduling information of the multicast channel specifies which subframes will be allocated to the next MSP. A specific MTCH (multicast traffic channel) is used to transmit the corresponding session data. When the base station detects that a session has not been actually delivered, it will configure an invalid indication in the scheduling information of the sent multicast channel.

Specifically, the scheduling information of the multicast channel also includes the logical channel identifier of the session and the number of the subframe where the multicast service channel corresponding to the logical channel identifier stops transmitting. On this basis, the base station will also configure corresponding invalid indications for sessions that have not been actually delivered in the scheduling information of the multicast channel. That is to say, when the base station configures an invalid indication in the scheduling information of the multicast channel, the scheduling information of the multicast channel includes at least three types of information, which are the logical channel identifier of each session and the multicast corresponding to the logical channel identifier. The number of the subframe where the traffic channel stops transmitting, and the corresponding invalid indication is configured for the session that is not actually delivered.

For example, when the base station carries 3 sessions, namely Session 1, Session 2 and Session 3, the base station detects that Session 2 has not been actually delivered. At this time, the base station will still allocate a certain number of subframes for Session 2 and provide these subframes. The frame allocates MTCH for transmission, for example, MTCH2. The base station will also send scheduling information of the multicast channel to the terminal. The scheduling information of the multicast channel includes an invalid indication for indicating that the session 2 is invalid, and may also include the logical channel identifier corresponding to MTCH2 and the subframe number where MTCH2 stops transmitting.

The configuration invalid indication can be performed by setting the status bit. For example, it can be implemented by the following steps included in step S102: setting the status bit from the first state to the second state.

For the scheduling information of the multicast channel, since the base station configures an invalid indication through the scheduling information of the multicast channel, at least one status bit may be preset in the scheduling information of the multicast channel for configuring the invalid indication. The status bit can include two states, namely the first state and the second state. The second state is used to indicate that the session is invalid, and the first state is used to indicate that the session is valid.

In a specific implementation scenario, when the preset state bit is 1 bit, the first state may be "0" and the second state may be "1". When the preset status bit is 2 bits, the first status can be "00" and the second status can be "11". It can be understood that there is no specific limit to the number of status bits, as long as the first status and the second status can be distinguished. When the status bit is 1 bit, the subframe number of the multicast service channel corresponding to the logical channel identifier to stop transmission is 10 bits. When the status bit is 2 bits, the subframe number is 9 bits.

In another implementation scenario, since the scheduling information of the multicast channel only includes the logical channel identifier (LCID) of each session and the subframe number (Stop MTCH) of the multicast traffic channel corresponding to the logical channel identifier, the base station can One of the bits occupied by the subframe number where the multicast traffic channel stops transmitting is used to configure the invalid indication.

Please refer to FIG. 4, which is a schematic diagram of configuring an invalid indication in the service scheduling method of the enhanced broadcast multicast service of the present application. For example, for session 1, the original multicast traffic channel stop transmission subframe number (Stop MTCH) occupies 11 bits, then the base station uses one of the bits to configure the invalid indication, the multicast service at this time The number of bits occupied by the subframe number (Stop MTCH) where the channel stops transmission becomes 10 bits. Of course, the base station can use several bits to configure the invalid indication, either by using the bits occupied by the subframe number where the original multicast service channel stops transmission, or by using the bits occupied by the logical channel identifier of a certain session.

S300: Send the configured scheduling information of the multicast channel to the terminals in the cell.

After the base station has configured an invalid indication for a session that is not actually issued, it will send the scheduling information of the multicast channel containing the invalid indication to the terminal in the cell covered by it to notify the terminal which session has not been actually issued. The occupied resources are invalid and there is no data transmission.

In a specific implementation scenario, when the base station configures a corresponding invalid indication for the session 2 that is not actually issued, the base station sends the scheduling information of the multicast channel containing the invalid indication to the terminal to notify the terminal of the session 2. It is not actually delivered, so that the terminal will not perform multicast monitoring on the resources occupied by session 2.

S400: If it is not actually delivered in the cell, stop delivering the session to the cell.

When the base station detects that some of the MBMS sessions it bears are not actually delivered, the sessions not actually delivered by the base station at this time still occupy a certain amount of air interface resources, but no data is actually transmitted. Therefore, the base station can choose to stop sending sessions that are not actually sent to the cell in the cell covered by it, so as to save air interface resources and improve the utilization efficiency of air interface resources.

In a specific implementation scenario, when the base station carries 3 sessions, which are sessions 1, 2 and 3, respectively. The MTCH allocated for session 2 is MTCH2. When session 2 is determined by the base station as not being actually delivered, the base station can stop delivering session 2 to the cell covered by it. Stopping session 2 means not transmitting multicast data in the air interface resources occupied by session 2, such as transmitting multicast data on MTCH2.

S500: Use resources occupied by the session to schedule other services.

In the same MBSFN transmission area, base station A detects that the session carried by it has not been actually delivered, but since other base stations can transmit the session normally, for base station A, the session that has not been actually delivered will not be released. Since the sessions that are not actually delivered are not used to transmit data, there is a waste of resources. Therefore, base station A can use resources occupied by sessions that have not been actually delivered to schedule other services, thereby improving resource utilization. During scheduling, the transmission power of other services can be set to be lower than the transmission power of the session not actually issued.

In a specific implementation scenario, when the session 2 carried by the base station A is not actually delivered, the subframe used to carry the session 2 does not actually have data transmission. After receiving the invalid information configured in the scheduling information of the multicast channel sent by the base station, the terminal will not perform multicast detection on the subframe resource where the session 2 is located. However, the base station can perform other service scheduling on the subframe resource where the session 2 is located, so as to make full use of the subframe resource and improve the efficiency of data transmission. Specifically, the base station may use the subframe where Session 2 is located to perform other services other than Session 2, such as multimedia broadcast/multicast services or unicast services.

Further, because base station A uses the subframes of session 2 to transmit other data, there may be interference with signals of other base stations. Specifically, if the data (that is, session 2 data) scheduled by base station A at the same time and the same resource is different from other cells, interference will occur. In order to reduce the probability of this occurrence, or to reduce the degree of interference, base station A can transmit other services performed by the base station at a transmission power lower than the transmission power required to transmit session 2 data. In this way, the cell covered by base station A can receive other service scheduling data performed by the base station, and can also reduce interference to other cells, achieve the effect of improving the utilization of air interface resources, and reduce the waste of air interface resources.

Please refer to FIG. 5. FIG. 5 is a schematic flowchart of a second embodiment of a service scheduling method for an enhanced broadcast multicast service according to the present application. Another embodiment of the service scheduling method for the enhanced broadcast multicast service of the present application may include the following steps:

S601: Receive scheduling information of the multicast channel from the base station.

When the base station uses E-MBMS for multicast broadcast to transmit MBMS data, it will send scheduling information to the terminal.

In a specific implementation scenario, the terminal may receive the scheduling information of the multicast channel sent by the base station. After the terminal receives the scheduling information of the multicast channel sent by the base station, the terminal will perform multicast monitoring on the subframe resources indicated by the scheduling information of the multicast channel to receive the sent MBMS data. Specifically, after receiving the scheduling information of the multicast channel, the terminal can obtain the session information to be sent by the base station and the MTCH used to transmit the session information by reading the scheduling information of the multicast channel, and the LCID corresponding to each MTCH Value and the number of the subframe where the MTCH stops transmitting, etc.

S602: Determine whether there is an invalid indication configured for the session in the scheduling information.

When sending session data, the base station can detect whether there is a session that has not been actually delivered. If there is a session that has not actually been delivered, the base station will configure an invalid indication for the session, specifically the scheduling information on the multicast channel Configure an invalid indication for the session in, and then send it to the terminal. After receiving the scheduling information sent by the base station, the terminal will detect whether there is an invalid indication of a certain session in the scheduling information. Specifically, when the scheduling information received by the terminal is the scheduling information of the multicast channel, it will detect whether there is an invalid indication configured for the session in the scheduling information of the multicast channel.

In a specific implementation scenario, the terminal receives the scheduling information of the multicast channel sent by the base station, and the three sent sessions are session 1, session 2, and session 3. The scheduling information of the multicast channel includes the MTCH configured for sessions 1, 2 and 3 for transmitting the session information, the LCID value corresponding to each MTCH, and the subframe number of the MTCH to stop transmission. When there is an invalid indication configured for the session in the scheduling information of the multicast channel, for example, the invalid indication configured for session 2, then in the scheduling information of the multicast channel, the scheduling information of the corresponding session 2 will not only include The MTCH of the transmission session 2 and the LCID value corresponding to the MTCH and the number of the subframe where the MTCH stops transmission will also include an invalidation indicator, which is used to indicate that the session 2 is invalid.

When the terminal detects that there is no invalid indication information in the scheduling information of the multicast channel, it continues to perform multicast resource monitoring for all sessions.

S603: If there is an invalid indication, cancel the multicast resource monitoring of the session corresponding to the invalid indication.

When the terminal detects that there is an invalid indication configured for a session in the scheduling information, it will not perform multicast resource monitoring for the session. Specifically, when the terminal receives the scheduling information of the multicast channel, if the scheduling information indicates that a session is invalid, the MTCH that transmits the session will not be monitored.

In a specific implementation scenario, in the scheduling information of the multicast channel received by the terminal, an invalid indication indicating that the session 2 is invalid is detected, and at the same time, the LCID value corresponding to the MTCH2 and MTCH2 used to transmit the session 2 and the MTCH2 stop are detected. The number of the transmitted subframe. Then the terminal will not perform multicast resource detection on MTCH2.

S604: Monitor other services performed on the resources occupied by the session corresponding to the invalid indication.

After detecting that the transmitted session is invalid, the base station can use the resources of the session to schedule other services. At this time, the terminal can also respond to other service scheduling performed by the base station accordingly to perform corresponding monitoring.

In a specific real-time scenario, when the base station uses the resources of the invalid session 2 to perform unicast transmission, the terminal can use the resources of the session 2 to monitor the corresponding unicast transmission according to the scheduling of the base station. When the base station is performing non-multimedia broadcast/multicast services, the terminal can also perform corresponding monitoring.

Different from the prior art, the base station detects whether the session is actually delivered in the cell, and when it detects that the session is not actually delivered in the cell, it configures the corresponding invalid indication for the session in the scheduling information of the multicast channel, and changes The configured scheduling information of the multicast channel is sent to the terminal in the cell, and the invalid indication can be used to indicate that the terminal session is not actually delivered in the cell, so that the terminal does not perform multicast on the subframe resources where the part of the session is located. Resource monitoring to achieve power saving effect.

Please refer to FIG. 6, which is a schematic diagram of a framework of an embodiment of a communication base station of the present application. The communication base station 60 includes a processor 61 and a memory 62 that are coupled to each other. The processor 61 is configured to execute a computer program stored in the memory 62 to execute the method described in the first embodiment of the service scheduling method for the enhanced broadcast multicast service. .

Please refer to FIG. 7, which is another schematic diagram of the framework of the communication base station embodiment of the present application. The communication base station 70: a judgment module 71, an adjustment module 72, and a sending module 73. The judging module 71 is used to judge whether the session is actually delivered in the cell. If the determining module 71 determines that the session is not actually delivered in the cell, the adjusting module 72 is configured to configure a corresponding invalid indication for the session in the scheduling information of the multicast channel. The sending module 73 is configured to send the configured scheduling information of the multicast channel to the terminals in the cell.

Wherein, at least one status bit is preset in the scheduling information of the above-mentioned multicast channel. The aforementioned adjustment module 72 is configured to perform configuration of a corresponding invalid indication for the session in the scheduling information of the multicast channel, including setting the status bit from the first state to the second state.

Wherein, the foregoing scheduling information of the multicast channel further includes the logical channel identifier of the session and the number of the subframe where the multicast service channel corresponding to the logical channel identifier stops transmitting, wherein the status bit is 1 bit and the subframe number is 10 bits.

Among them, the judgment module 71 is used to judge whether the session is actually issued in the cell, which specifically includes: judging whether the session is received by the terminal in the cell, or whether the session fails to be established in the cell; if it is not received by the terminal or the establishment fails, then It is determined that it is not actually delivered in the cell.

Wherein, if the above-mentioned session is not actually issued in the cell, the sending module 73 is also configured to stop issuing the session to the cell.
