Method and device for transmitting and receiving MBMS service related messages

The present invention relates to multimedia broadcast multicast service (MBMS) communication technology. More specifically, the present invention relates to methods and apparatus for transmitting and receiving MBMS service related messages to ensure that MBMS capable user equipment receives MBMS services.

This section is intended to provide a background or context to the invention as described in the claims. The description herein may include concepts that may have been explored, but are not necessarily those that have been previously contemplated or explored. Therefore, the contents mentioned in this section are not prior art to the specification and patent application scope of the present application, and are not admitted to be prior art as included in this section.

The Third Generation Partnership Project (3GPP) has defined MBMS for simultaneously delivering multimedia content to a large set of receivers. The 3GPP has published a set of MBMS specifications covering all aspects of this service from radio access to content delivery applications and protocols.

Carrier Aggregation (CA) is a technique in LTE-A that serves a user equipment by aggregating multiple carriers. As is well known, in a multicast broadcast single frequency network (MBSFN), a user equipment UE can receive an MBMS (Multimedia Broadcast Broadcast Service) service. However, the definition of the service area (SA) for MBMS is a geographical concept. It defines the geographic area in which the MBMS service is provided. On the other hand, for the MBSFN area definition, it combines the service area and the frequency layer (in other words, the carrier component under the carrier set (CA)), wherein the pin The geographic area and frequency band are defined for the MBMS service MBSFN transmission. It can be seen from this that the MBSNF area and the service area are service specific rather than user equipment specific. And the MBSNF area and the service area correspond to specific geographical areas.

In the service area, multiple carrier components can be configured in the same service area (the same geographical area). A primary cell (PCell) and a secondary cell (SCell) are defined for one user equipment. Different user devices in a service area have different primary cells according to their channel conditions. It can be clearly seen that the primary cell and the secondary cell in the service area are user device specific.

There is a layout scheme in which a plurality of carrier component cells overlapping in the same geographical area belong to the same service area.

However, the provision of current MBMS services is always pre-configured in a determined frequency carrier. However, such a scheme has the following problems. Since different user equipments are connected to different primary cells (different carrier component cells) due to different channel conditions, different carrier components will be configured in different neighboring cells. This makes it impossible to have all of the MBMS services received by all UEs having MBMS capability in one geographical area. In addition, the user equipment connected to one carrier component cell cannot obtain all the knowledge of the MBMS service providing information in the service area (geographic area). That is to say, the user equipment connected to its primary cell can only know the related information of the MBMS service provided by its primary cell and then receive the MBMS service provided by its primary cell (if any), but cannot know that it is not connected to the secondary device. The related information of the MBMS service (if any) provided by the cell and thus unable to receive the MBMS service provided by its secondary cell.

Accordingly, it is an object of the present invention to provide a method and apparatus for transmitting and receiving MBMS service related information to ensure that an MBMS capable user device can be informed of its service area (geographic area). Information about all MBMS services and, in turn, receiving MBMS services of interest.

According to a first aspect of the present invention, a method for transmitting a message to a user equipment in a service area is provided, where a plurality of carrier component cells of carrier aggregation are included in a service area, wherein a current cell group in which the user equipment is located is provided. One of the carrier component cells, the message is a message of MBMS service information of one or more neighboring cells in the service area of the same geographical area, and the method includes: defining a message cell of the message, wherein the message is The element includes the MBMS service ID information of the MBMS service and the corresponding cell ID information; and the message cell is sent to the user equipment.

According to a second aspect of the present invention, a device for transmitting a message to a user equipment in a service area is provided, where a plurality of carrier component cells of a carrier aggregation are included in a service area, where a current cell group of the user equipment is located One of the carrier component cells, the message is a message of MBMS service information of one or more neighboring cells in the service area of the same geographical area, and the method includes: a device for defining a message cell of the message The message cell includes the MBMS service ID information of the MBMS service and the corresponding cell ID information; and means for transmitting the message cell to the user equipment.

In the above two aspects, preferably, the message cell is MBMS control frequency. New cell of the channel (MCCH) message. The message cell is preferably included in the system information block SIB5 or SIB13.

According to a third aspect of the present invention, a method for receiving a message by a user equipment in a service area is provided, where a plurality of carrier component cells of a carrier aggregation are included in a service area, where a current cell group of the user equipment is located One of the carrier component cells, the message is a message of MBMS service information of one or more neighboring cells in the service area of the same geographical area, and the method includes: receiving a message cell, where the message cell includes The MBMS service ID information of the MBMS service and the corresponding cell ID information; obtaining the MBMS service ID of the neighboring cell according to the message cell; and acquiring the corresponding MBMS service according to the MBMS service ID.

According to a fourth aspect of the present invention, a device for receiving a message by a user equipment in a service area is provided, where a plurality of carrier component cells of a carrier aggregation are included in a service area, where a current cell of the user equipment is located One of the carrier component cells, the message is a message of MBMS service information of one or more neighboring cells in the service area of the same geographical area, and the device includes: means for receiving the message cell, wherein The message cell includes the MBMS service ID information of the MBMS service and the corresponding cell ID information; means for obtaining the MBMS service ID of the neighboring cell according to the message cell; and means for obtaining the corresponding MBMS service according to the MBMS service ID.

By using the method and device of the present invention for transmitting a message to a user equipment in a service area, the MBMS capable user equipment can be obtained related to all MBMS services in the service area in which it is located. The MBMS service information is further based on the MBMS service information to receive the MBMS service of interest.

Other objects and effects of the present invention will become more apparent from the detailed description of the invention.

In all of the following figures, the same reference numerals indicate the same or similar features or functions.

Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Figure 1 schematically illustrates an environment in which the present invention may be implemented.

As shown in FIG. 1, without loss of generality, the service area 1 includes an MBSFN area 1 that provides MBMS service 1, a non-MBSFN area 2 that does not provide any MBMS service, and an MBSFN area 3 that provides MBMS service 2. It should be understood that the service area may include any number of MBSFN areas or non-MBSFN areas. The cell 1 and the cell 2 constitute the MBSFN area 1 in the service area 1, and in the MBSFN area 1, the MBMS service 1 is provided by the carrier component 1 to the user equipment connected to the node B of the cell 1 or the cell 2. The cell 3 constitutes a non-MBSFN area in the service area 1, in which the non-MBMS service is provided by the carrier component 2 to the user equipment connected to the Node B of the cell 3 without providing any MBMS service. The cell 4 and the cell 5 constitute the MBSFN area 2 in the service area 1, in which the MBMS service 2 is provided by the carrier component 3 to the user equipment connected to the node B of the cell 4 or the cell 5. It should be understood that any number of cells may be included in an MBSFN area or a non-MBSFN area, and each cell may serve any number of user equipments. In order not to obscure the present invention, Node B is not shown in the figure.

In the prior art, for example, the user equipment UE 11 connected to the Node B of the cell 1 can only obtain MBMS service information about the MBMS service 1 and receive the MBMS service 1. Although the UE 11 is located in the service area 1, it cannot know the information related to other MBMS services (for example, MBMS service 2) in the service area 1, and is even less able to receive the MBMS service 2. Similarly, the user equipment UE 41 connected to the Node B of the cell 4 can only obtain MBMS service information about the MBMS service 2 and receive the MBMS service 2. Although the UE 41 is located in the service area 1, it cannot know the information related to other MBMS services (for example, MBMS service 1) in the service area 1, and is even less able to receive the MBMS service 1. For the user equipment UE 31 connected to the Node B of the cell 3, the cell 3 is a non-MBMS serving cell. Therefore, although the user equipment UE 31 is located in the service area 1, the MBMS service information related to any MBMS service (for example, MBMS service 1 and MBMS service 2) in the service area 1 cannot be known and any MBMS service is received.

In order to provide the related information of the MBMS service of other neighboring cells (for example, cell 4 and cell 5) to the user equipment UE 11 connected to the Node B of the cell 1, it may directly transmit on the MCCH of the cell 1 of the current carrier component 1. MBMS service information of other neighboring cells.

However, it is inefficient to directly transmit the overall MBMS service configuration message of the cell of other adjacent carrier components to the user equipment, because the amount of information to be sent is relatively large, and not all MBMS services are The user of the user device wishes to receive it.

Therefore, since the MBMS service can be uniquely identified by the MBMS service ID information, preferably, according to an embodiment of the present invention, only the message of the MBMS service ID information of the cells of other adjacent carrier components is sent to the user setting. The device (eg user device UE 11) is not the overall MBMS service configuration information itself.

2 is a flow chart that schematically illustrates a method of transmitting a message to a user device in accordance with one embodiment of the present invention.

The method 200 as shown in FIG. 2 is implemented in an environment such as that shown in FIG. The service area to which the method 200 is applied includes a plurality of carrier component cells of the carrier aggregation, where the current cell is located in one of the plurality of carrier component cells, and the message is in the same geographical area as the current cell. The method 200 includes, in step S210, a message cell that defines the message, where the message cell includes the MBMS service ID information of the MBMS service and the corresponding cell ID information, where the message of the MBMS service information of the one or more neighboring cells in the area is used; And in step S220, the message cell is sent to the user equipment.

For example, referring to FIG. 1 , the user equipment UE 11 is taken as an example, and the message defined by the method of the present invention is sent to the user equipment UE 11 in the service area 1. The user equipment UE 11 is located in the current cell, and the user is located in the current cell. The current cell Cell 1 in which the device UE 11 is located is one of a plurality of carrier component cells. The message is related to the MBMS service of one or more neighboring cells (Cell 2, Cell 3, Cell 4, and/or Cell 5, etc.) in the service area 1 of the current cell 1 in the same geographical area, in the cell 1 And different neighboring cells provide different MBMS services (eg, MBMS service 1 or 2, etc.) or no MBMS services (eg, cell 3) by different carrier components (eg, carrier component 1, 2 or 3). A message cell defining a message, wherein the message cell can include an MBMS service of an MBMS service (eg, MBMS service 2) of a neighboring cell ID information. Preferably, the message cell further includes cell ID information of a neighboring cell (e.g., cell 4 and cell 5) to which the corresponding carrier component belongs. The message cell is then sent to the user equipment UE 11.

However, in this way, for a cell (eg, cell 3) to which a carrier component (eg, carrier component 2) that does not currently belong to any MBSFN region belongs, there is no MBMS-related configuration information and a control plane channel MCCH associated with the MBMS service. The user equipment thus connected to the Node B of the cell 3, for example, the UE 31 will not be able to obtain the MBMS service information of other neighboring cells.

To this end, in accordance with a preferred embodiment of the present invention, the message cell is a new message cell of the MCCH message, such as a "neighCellMbmsInfoList" cell, to indicate MBMS service information for the neighboring cell. The cell is sent to the user equipment of the cell by the MCCH channel to make the user equipment know the MBMS service information of the neighboring cell. Preferably, the new MCCH message cell may include MBMS service ID information and corresponding cell ID information. More preferably, the MBMS service ID information may include inter-frequency neighbor cell MBMS service ID information and intra-frequency neighbor cell MBMS service ID information.

The "neighCellMbmsInfoList" cell can be defined in detail as follows:

"neighCellMbmsInfoList" cell

Further preferably, for the above preferred embodiment, in order to enable a carrier component cell located in a non-MBSFN area that does not provide MBMS service The user equipment in (for example, cell 3) can also obtain the information related to the MBMS service of the neighboring cell in the service area 1 and receive the corresponding MBMS service, and the system information block SIB13 needs to cooperate, because The relevant MBSFN subframe resources and MCCH configuration information are defined in SIB13. For example, the method according to the present invention further includes: modifying the definition of the current SIB 13 to indicate MCCH configuration information to a cell that does not belong to any MBSFN area (ie, does not provide an MBMS service), and of course the SIB 13 may directly include other neighboring cells. Information about MBMS services. More specifically, the value range of the cell "MBSFN-AreaInfoList" of the SIB 13 can be modified according to the method of the present invention such that the SIB 13 includes an empty MBSFN area information list indicating that the carrier component cell does not belong to any MBSFN area.

Alternatively, in the SIB 13, a preset value may be defined for the cell related to the MBSFN area in the system information block SIB13, where the preset value indicates that the carrier component cell does not belong to any MBSFN area, where the MBSFN area is to provide the MBMS service. region. For example, if the current cell (cell 3) of the user equipment (for example, the UE 31) does not belong to any MBSFN area, the preset value is sent to the current cell, so that the current cell has the MCCH channel, so that the user equipment UE 31 obtains other phases. A message cell of an MBMS service ID of a cell adjacent to the carrier component, and receiving a corresponding MBMS service according to the message cell.

According to another preferred embodiment of the present invention, the information cell related to the MBMS service of the neighboring cell may not be transmitted on the MCCH channel, but the information cell related to the MBMS service of the neighboring cell may be included in the system information area. Letter to the user equipment of the carrier component cell in the service area No. sent.

For example, in a preferred embodiment, method 200 includes a new message cell in SIB 13 to signal information about the MBMS service provided by the neighboring cell, which may be represented, for example, as a "neighCellMbmsInfoList" cell.

In another preferred embodiment, the method 200 is associated with a message cell associated with the MBMS service provided by the neighboring cell for inclusion in the SIB5 for signaling. System Information Block Type 5 (SIB5) is defined in the current RRC Agreement TS36.331 for related information of inter-frequency cell reselection. According to the preferred embodiment, the SIB5 can be used to notify the user in the carrier component cell of the related information of the MBMS service of the neighboring cell. In particular, SIB5 may include information related to inter-frequency carriers of all neighboring cells including the carrier component. Therefore, a cell (for example, MBMS service ID information) "mbms-ServiceIdList" field associated with an MBMS service of another carrier component cell (which may also be referred to as a neighbor cell) may be added to the "interFreqNeighCellInfo" cell of SIB5. . As shown in the following table, the detailed definition of "mbms-ServiceIdList" is included in SIB5:

System information block type 5 cells

The newly added field "mbms-ServiceIdList" indicates the MBMS service ID information list of the MBMS service provided by the inter-frequency neighboring cell.

In the above preferred embodiment in which the cell related to the MBMS service of the neighboring cell to be transmitted is included in the SIB5 and the SIB13 for signal transmission, the processing of the signaling mechanism is implemented by the following steps.

In the service area, the cell modification of SIB5 or SIB13 is triggered when a service session starts or stops. Node B updates SIB5 or SIB13 (depending on Whether SIB5 or SIB13 is modified), and the update is sent to the user device by paging message. In addition, the Node B further sends the modified SIB5 or SIB13 to the user equipment.
