Description

MBMS information transmission method, user equipment and network side equipment

The embodiments of the present invention relate to communication technologies, and in particular, to an MBMS information transmission method, a user equipment, and a network side device. Background technique

The Multimedia Broadcast Multicast Service (MBMS) was redefined in the ninth version of the 3rd Generation Partnership Project (3GPP) (Release d for Rel-9). The MBMS not only enables multicast and broadcast of low-rate plain text messages, but also enables multicast and broadcast of high-rate multimedia service messages.

Before the service data transmission is performed based on the MBMS, the network side device periodically periodically multicasts the channel scheduling information according to the MCH Scheduling Period (MSP).

The Multicast Channel Scheduling Information (MSI) is sent to the User Equipment (UE). The MSI is used to allocate resources to different Multicast Traffic Channels (MTCHs), and different MTCHs correspond to different sessions. The UE learns the transmission resources used by the MTCH corresponding to the session of interest according to the MSI received in the MSP, and acquires the session data packet transmitted on the MTCH. The length of the MSP period can be configured through a Multicast Control Channel (MCCH) message. However, the MSP configurable minimum period specified in the Rel-9 standard is 80ms.

Currently, MBMS technology mainly applies and transmits video programs such as TV programs to tolerate high latency services. Now consider using MBMS technology to carry Voice over Internet Protocol (VoIP) services to provide point-to-multipoint transmission of VoIP services. However, the generation period of the VoIP service call state data packet is short, such as 20 ms. The minimum period configurable by the MSP is only 80ms.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

3GPP has introduced MBMS technology in the Rd-6 version of the 3rd-generation mobile system (3G) to provide higher-speed service data transmission, and the MBMS technology in the Rel-9 version. Redefine. The MBMS technology referred to in this paper is applicable to higher communication systems than 3G communication systems, such as Long Term Evolution (LTE) communication systems.

FIG. 1 is a flowchart of a method for transmitting MBMS information according to Embodiment 1 of the present invention. The method of this embodiment is applicable to the case of using MBMS technology to carry VoIP services. The method is performed by the UE and can usually be implemented by hardware and/or software. The method in this embodiment specifically includes the following:

Step 101: Receive first multicast channel scheduling information MSI sent by the network side device, where the first MSI carries a period indication.

Step 102: Receive a second MSI sent by the network side device according to the receiving period indicated by the period indication.

Specifically, the first MSI refers to an MSI received by the UE before receiving the first session data packet sent by the network side device. After receiving the first MSI, the UE may receive the session data packet carried by the channel corresponding to the number according to the logical channel number carried in the first MSI. The first MSI may be a Media Access Control Control Element (MAC CE). The first MSI includes resource scheduling information of the MTCH corresponding to a logical channel identifier (LCID). Different LCIDs correspond to different MTCHs, and different MTCHs correspond to different sessions. After receiving the first MSI, the UE may determine, according to the LCID included in the first MSI, a logical channel to receive session data, and then receive a session data packet corresponding to the logical channel. For the MBMS bearer-based service, the UE needs to receive an MSI sent by the network side device before receiving a data packet. Then, after receiving the first session data packet, the user equipment needs to receive an MSI, that is, the second MSI, before receiving the second session data packet. The time when the user equipment receives the second MSI determines the time when the user equipment receives the second session data packet.

The receiving period indicated by the period indication carried in the first MSI may be a period in which the user equipment receives the second MSI. The generation period of the session data packets is different in different states, and the period in which the user equipment receives the session data packets is also different. Therefore, the reception periods configured in different service states are also different. If the service status of the MTCH of the different channel number is different, the MTCH indicating that the channel number is different may correspond to one period indication; if the service status corresponding to the MTCH of the different channel number is the same, the period indication may be all MTCHs with different channel numbers correspond to one cycle indication.

The user equipment needs to receive the MSI sent by the network side device before receiving the session data packet. As long as the period in which the user equipment receives the MSI is determined, the period in which the user equipment receives the session data packet can be determined. The receiving period of the period indication may be preset as the generation period of the session data packet, thereby avoiding the service delay caused by the MSI receiving period being greater than the generation period of the session data packet.

In this embodiment, the user equipment may receive the second MSI according to the receiving period indicated by the received periodic indication in the first MSI, so that the receiving period of the MSI is no longer restricted by the sending period, that is, the MSP. Therefore, the user equipment can receive the session data packet period, reduce the delay of the VoIP service, and improve the service quality.

At the same time, the period indication has a clear indication of the length and duration, to avoid the VoIP service in a silent state.

The UE only needs to receive the next MSI according to the receiving period indicated by the period indication, and there is no case that the UE receives one session data packet to receive multiple MSIs, thereby avoiding extra power consumption of the UE.

On the basis of the foregoing embodiment, the second embodiment of the present invention further provides a method for transmitting MBMS information.

Further, in the above solution, the period indication includes a long period indication and/or a short period indication. The receiving period indicated by the long period indication is greater than the receiving period indicated by the short period indication. Specifically, the period indication may include a long period indication, or a short period indication, or a combination of long and short period indications. Specifically, it can be represented by different assignments of the period indication. For example, the assignment of 1 indicates a long period indication, and the assignment 0 indicates a short period indication; it may also be a long period indication by assigning a value of 0, and a short period indication by an assignment of 1. VoIP services usually have two states, call state and silent state. The VoIP service in the call state has a shorter generation period of the session data packet, and the VoIP service in the silent state has a longer generation period of the session data packet. For the MTCH that carries the VoIP service in the call state, the corresponding period indication is the short period indication, and the corresponding MTCH that carries the silent state VoIP service, and the corresponding period indication is the long period indication.

The specific size of the receiving period indicated in the long-period indication and the short-period indication may be that the network-side device is configured according to the service status, and the user equipment is notified, and the user equipment may actively configure according to the predetermined rule.

Further, the period indication is carried in the message header and/or message content of the first MSI. The MSI is a MAC CE format in the MAC CE format, including the message header corresponding to the MAC CE and the content of the MAC CE message. Its message header consists of six fields: R, R, E, LCID, F, and L. Where R is the Reserve bit, that is, reserved bits; E indicates whether there are other message headers subsequently; F indicates the length of the L field, and L indicates the length of the MSI MAC CE. Generally, the L length is 7 bits, that is, the MSI message content can be up to 127 bytes. The MAC CE includes a variety of different formats. The LCID indicates that the MAC CE is an MSI MAC CE and the LCID is 5 bits long.

The message content includes the LCID and the subframe number indication. The LCID is different from the LCID in the message header. The LCID is mapped to the MTCH of different logical channel numbers to correspond to different service sessions. The subframe number is indicated as Stop MTCH, and the content of the MSI message includes multiple LCIDs and the corresponding Stop MTCHo Stop MTCH indicates the last subframe corresponding to the service session data carried on the MTCH mapped by the LCID corresponding thereto in the transmission period. Serial number. For example, if the value of the Stop MTCHn is 4, it indicates that the service session data carried on the MTCH mapped by the LCIDn is blocked by the Multicast Broadcast Single Frequency Network (MBSFN) subframe of the sequence number of 4 in the transmission period. on. After receiving the MSI, the UE receives the session data packet sent by the network side device.

The period indication may be carried in the message header of the first MSI, the content of the message, or both.

If the periodic indication is carried in the message header of the first MSI, it may be carried in the reserved bit of its message header. Since the message header of the MSI includes a 2 bit reserved bit, the message bit can be carried in the first reserved bit, or can be carried in the second reserved bit, or can be carried in combination with two reserved bits. Belt. For example, if the period indication is carried in the first reserved bit, the long period indication may be carried by 1 and the short period indication may be carried by 0. Correspondingly, if the period indication is carried in the second reserved bit, it may be similar. The method indicates that if two reserved bits are carried in combination, the long period indication may be carried by 01, the short period indication may be carried by 00, and 10 and 11 may also be used to carry other indication messages.

If the period indicates the content of the message carried in the first MSI, it may be a Stop MTCH corresponding to the LCID that does not map any session, or may be an idle bit carried in the Stop MTCH corresponding to the LCID of the mapped session. For the LCIDs that are not mapped to any session, since the Stop MTCH corresponding to each LCID is a libit, the 11-bit bits of the Stop MTCH may respectively carry a period indication, and each period indicates a corresponding LCID, that is, corresponding to one logical channel. . The period indication carried by the Stop MTCH corresponding to the LCID of which no session is mapped may be a plurality of period indications, which respectively correspond to different logical channels.

If all LCIDs in the first MSI are mapped to different sessions, the period indication may also be carried by the idle bits in the Stop MTCH corresponding to the LCID of the mapped session. For the 11-bit Stop MTCH, there are usually some idle bits in addition to the sub-frame number. Therefore, the period indication by the Stop MTCH can be carried by a specific bit, such as the first bit, the last bit, the first three bits, or the last three bits. The stop MTCH carries the period indication, and the LCID corresponding to the Stop MTCH may be the LCID corresponding to a certain session. It should be noted that the period indication carried by the Stop MTCH may be one period indication or multiple period indications.

Further, on the basis of the foregoing embodiment, the network side device may further send a period indication to the user equipment according to the period indication control unit, where the period indication control unit may be a new MAC CE format control message, the new MAC CE It may be a pre-configured control unit for the required periodic conversion service, which includes a predetermined periodic indication bit without carrying the periodic indication by the existing MSI MAC CE. The new MAC CE may carry a long-period or short-period indication, and may also carry multiple long-period or short-period indications, one for each logical channel.

The solution of the embodiment, on the basis of the solution of the foregoing embodiment, provides a plurality of preferred achievable solutions by using a plurality of specific periodic indication carrying modes, thereby better solving the delay problem of the VoIP service call state and the silent state. Power consumption problem.

On the basis of the foregoing embodiment, the third embodiment of the present invention further provides a method for transmitting MBMS information. FIG. 2 is a flowchart of a method for transmitting MBMS information according to Embodiment 3 of the present invention. As shown in FIG. 2, in step 101 of the foregoing embodiment, the first MSI sent by the network side device is received. Before, the specifics include:

Step 201: Receive a control message sent by a network side device. The control message includes: a service type.

Step 202: Determine, according to the service type, a receiving period indicated by the long period indication and/or a receiving period indicated by the short period indication.

Specifically, the service type may be a specific status of the VoIP session service carried by the MBMS, such as a call state or a silent state, or may be a service identifier of the VoIP. Before receiving the control message, the UE pre-configures the length of the VoIP service in a long period of time. For example, if the VoIP service is in the call state, the long period is 160 ms, and the corresponding VoIP service is in the silent state, and the long period is 20 ms. After receiving the control message, the UE may determine the size of the reception period indicated by the long and short period indication according to the type of the service.

This embodiment also provides an MBMS information transmission method which is an alternative to the above scheme. FIG. 3 is a flowchart of another MBMS information transmission method according to Embodiment 3 of the present invention. As shown in FIG. 3, before receiving the first MSI sent by the network side device in step 101 in the foregoing embodiment, the method further includes:

Step 301: Receive a control message sent by the network side device. The control message includes: a periodic configuration parameter.

Step 302: Configure, according to the periodic configuration parameter, a receiving period indicated by the long period indication and/or a receiving period indicated by the short period indication.

Specifically, if the UE side does not pre-configure the long and short periods, the configuration may be configured according to the periodic configuration parameters included in the received control message sent by the network side device.

In the above scheme, the control message is a multicast control channel MCCH message or a dedicated control message. The MCCH message is an MBMS session control message, and the dedicated control message may be, for example, a Radio Resource Control (RRC) message. The network side device may send the control message to the user equipment when transmitting the MCCH change notification message or the RRC reconfiguration message.

Further, the network side device can also configure a shorter MSP period and/or an MCCH message interval, thereby shortening the time for establishing a connection to better support low-latency services.

In this embodiment, the call delay of the VoIP service can be reduced, and the power consumption of the UE caused by the silence of the VoIP service can be reduced.

Embodiment 4 of the present invention further provides an MBMS information transmission method. The method of this embodiment is performed by a network The network side device is implemented, usually by hardware and/or software. FIG. 4 is a flowchart of a method for transmitting MBMS information according to Embodiment 4 of the present invention. As shown in FIG. 4, the method specifically includes the following:

Step 401: Generate a first MSI, where the first MSI carries a period indication.

The network side device configures the period indication in the MSI to generate the first MSI of the carrying period indication. The network side device generates the first MSI, which may be before the network side device generates the first session data packet.

Step 402: Send the first MSI to the user equipment, so that the user equipment receives the second MSI according to the receiving period indicated by the period indication.

The time at which the network side device sends the first MSI may be before sending the generated first session data packet. After receiving the first MSI, the user equipment, according to the period indicated by the first MSI, indicates a second MSI that is subsequently sent by the network side device according to the indicated receiving period. The network side device sends an MSI before sending a session data packet. If the network side device needs to send the N session data packets to the user equipment, the N-1 MSIs may not carry the period indication.

The solution in this embodiment can reduce the call delay of the VoIP service, improve the service quality, and reduce the power consumption of the UE when the VoIP service is silent.

Further, in the above solution, the period indication includes a long period indication and/or a short period indication; wherein, the long period indication indicates that the reception period is greater than the reception period indicated by the short period indication. Further, the period indication in the foregoing embodiment may be carried in a message header and/or message content of the first MSI.

Further, if the period indication is carried in the message header of the first MSI, the period indication is carried in the reserved bit of the message header of the first MSI.

On the basis of the foregoing embodiment, the solution, before the sending the first MSI to the user equipment in the foregoing step 402, specifically includes:

Sending a control message to the user equipment; the control message includes: a service type;

And a service type, configured to instruct the user equipment to determine a reception period indicated by the long period indication and/or a reception period indicated by the short period indication.

Step 502: The network side device generates a first MSI, where the first MSI carries a period indication.

Step 503: The network side device sends the first MSI to the user equipment.

Step 504: The user equipment configures the long receiving period and/or the short receiving period according to the received control message.

The long receive period and/or the short receive period means that the user equipment performs a receive cycle transition, that is, a receive cycle required to receive the next MSI. The configuration of the receiving period of the user equipment may further enable the length of the receiving period in different states to be pre-configured on the user equipment side. After receiving the MCCH message or the RRC message sent by the network side device, determining the specificity according to the service type included in the message. The length of the receive cycle.
