Description
本發明係關於多媒體廣播群播服務(MBMS)通訊技術。更具體而言,本發明係關於用於發送及接收MBMS服務相關訊息的方法及設備,以確保具有MBMS能力之使用者設備接收MBMS服務。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.
本部分旨在對申請專利範圍中細述之本發明提供背景或上下文。此處之描述可包括可能被探究過之概念,但未必都是之前已經想到或探究之那些概念。因此,除了在此明確指出之外,本部分提及之內容對於本申請之說明書及申請專利範圍而言並非先前技術,且並不因為包括在本部分中就承認其為先前技術。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.
第三代合作夥伴計畫(3GPP)已經定義了MBMS,用於同時將多媒體內容遞送至大的接收器集合。3GPP已經公佈了MBMS規範集合,其覆蓋了此服務自無線電存取至內容遞送應用及協定之所有方面。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.
載波聚合(CA)係LTE-A中之一種技術,其藉由聚合多個載波來服務使用者設備。眾所周知,在群播廣播單頻網路(MBSFN)中,使用者設備UE都可接收MBMS(多媒體廣播群播服務)服務。但是,針對MBMS之服務區域(SA)之定義係一個地理概念。它定義了提供MBMS服務之地理區域。另一方面,對於MBSFN區域定義而言,它組合了服務區域及頻率層(換言之載波集合(CA)下之載波分量),其中,針 對MBMS服務MBSFN傳輸定義了地理區域及頻帶。由此可以很清楚,MBSNF區域及服務區域皆係服務特定的而非使用者設備特定的。且MBSNF區域及服務區域皆係與具體地理區域相對應的。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.
在服務區域中,在相同服務區域(相同地理區域)中可配置有多個載波分量。對於一個使用者設備定義了主小區(PCell)及輔小區(SCell)。在一個服務區域中之不同使用者設備按照其頻道條件具有不同之主小區。由此可以很清楚,服務區域中之主小區及輔小區係使用者設備特定的。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.
存在如下佈局方案:在相同地理區域中重疊之多個載波分量小區屬於相同服務區域。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.
然而,當前MBMS服務之提供總是在一個經判定頻率載波中進行預組態。然而,此種方案存在如下問題。由於不同使用者設備因不同頻道條件而連接至不同主小區(不同載波分量小區),且不同載波分量將被配置在不同之相鄰小區中。這導致不可能使在一個地理區域中具有MBMS能力之所有UE都接收到所有MBMS服務。另外,連接至一個載波分量小區之使用者設備無法獲得在該服務區域中(地理位置區域)之MBMS服務提供資訊之所有知識。也就是說,連接至其主小區之使用者設備只能獲知其主小區提供之MBMS服務之相關訊息並進而接收其主小區提供之MBMS服務(若存在),而無法獲知其未連接至之輔小區提供之MBMS服務(若存在)之相關訊息並進而無法接收其輔小區提供之MBMS服務。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.
因此,本發明之目的係提供一種方案,以提供一種用於發送及接收MBMS服務相關訊息的方法及設備,以確保具有MBMS能力之使用者設備能夠獲知其所在服務區域(地理位置區域)中之所有MBMS服務之相關資訊並進而接收感興趣之MBMS服務。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).

在所有之下述附圖中,相同之標號表示具有相同、相似或相應之特徵或功能。In all of the following figures, the same reference numerals indicate the same or similar features or functions.
以下參考附圖來詳細描述本發明之實施方式。Embodiments of the present invention are described in detail below with reference to the accompanying drawings.
圖1示意性地示出了本發明可在其中實施之環境。Figure 1 schematically illustrates an environment in which the present invention may be implemented.
如圖1所示,不失一般性,在服務區域1中,包含有提供MBMS服務1之MBSFN區域1、不提供任何MBMS服務之非MBSFN區域2以及提供MBMS服務2之MBSFN區域3。應理解,服務區域可包含任意數量之MBSFN區域或非MBSFN區域。小區1及小區2構成服務區域1中之MBSFN區域1,在該MBSFN區域1中藉由載波分量1提供MBMS服務1至連接至小區1或小區2之節點B之使用者設備。小區3構成服務區域1中之非MBSFN區域,在該非MBSFN區域中藉由載波分量2提供非MBMS服務至連接至小區3之節點B之使用者設備,而不提供任何MBMS服務。小區4及小區5構成服務區域1中之MBSFN區域2,在該MBSFN區域2中藉由載波分量3提供MBMS服務2至連接至小區4或小區5之節點B之使用者設備。應理解,在MBSFN區域或非MBSFN區域中可包含任意數量之小區,每個小區可服務任意數量之使用者設備。為了不模糊本發明,在圖中未示出節點B。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.
在先前技術中,例如連接至小區1之節點B之使用者設備UE 11只可獲得有關MBMS服務1之MBMS服務資訊以及接收MBMS服務1。雖然UE 11位於服務區域1,但卻無法獲知服務區域1中其他MBMS服務(例如MBMS服務2)相關之資訊,更無法接收MBMS服務2。類似地,連接至小區4之節點B之使用者設備UE 41只可獲得有關MBMS服務2之MBMS服務資訊以及接收MBMS服務2。雖然UE 41位於服務區域1,但卻無法獲知服務區域1中其他MBMS服務(例如,MBMS服務1)相關之資訊,更無法接收MBMS服務1。對於連接至小區3之節點B之使用者設備UE 31,由於小區3係非MBMS服務小區。因此,雖然使用者設備UE 31位於服務區域1,但卻無法獲知服務區域1中任何MBMS服務(例如,MBMS服務1及MBMS服務2)相關之MBMS服務資訊以及接收任何MBMS服務。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.
為了提供其他相鄰小區(例如,小區4及小區5)之MBMS服務之相關訊息至連接至小區1之節點B之使用者設備UE 11,可直接在當前載波分量1之小區1之MCCH上發送其他相鄰小區之MBMS服務資訊。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.
但是,將其他相鄰載波分量之小區之整體MBMS服務組態訊息直接發送至其中之使用者設備比較低效,因為需要發送之訊息量相對而言比較大,且其中並非所有的MBMS服務皆係使用者設備之用戶所希望接收的。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.
因此,由於MBMS服務可由MBMS服務ID資訊來唯一地標識,較佳地,根據本發明之實施方式,僅將其他相鄰載波分量之小區之MBMS服務ID資訊之訊息發送至使用者設 備(例如使用者設備UE 11),而非整體MBMS服務組態資訊本身。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.
圖2示意性地示出了根據本發明之一個實施方式之將訊息發送至使用者設備之方法之流程圖。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.
如圖2所示之方法200在例如圖1所示之環境中實現。在方法200所應用之服務區域中包含載波聚合之多個載波分量小區,其中使用者設備所位於之當前小區係多個載波分量小區中之一個小區,訊息係與當前小區位於相同地理區域之服務區域中之一個或多個相鄰小區之MBMS服務資訊之訊息,方法200包括步驟S210,定義該訊息之訊息信元,其中訊息信元包含MBMS服務之MBMS服務ID資訊及對應之小區ID資訊;以及步驟S220,將訊息信元發送至使用者設備。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.
例如,參見圖1,以使用者設備UE 11為例,在該服務區域1中將本發明方法所定義之訊息發送至使用者設備UE 11,其中使用者設備UE 11位於當前小區中,使用者設備UE 11所位於之當前小區Cell 1係多個載波分量小區中之一個小區。訊息係與當前小區1位於相同地理區域之服務區域1中之一個或多個相鄰小區(小區2、小區3、小區4及/或小區5等等)之MBMS服務相關之訊息,在小區1及相鄰小區中藉由不同載波分量(例如,載波分量1、2或3)提供不同MBMS服務(例如,MBMS服務1或2等)或不提供MBMS服務(例如,小區3)。定義訊息之訊息信元,其中訊息信元可包含相鄰小區之MBMS服務(例如MBMS服務2)之MBMS服務 ID資訊。較佳地,訊息信元進一步可包含對應載波分量所屬之相鄰小區(例如小區4及小區5)之小區ID資訊。然後,將訊息信元發送至使用者設備UE 11。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.
但是,以此方式,對於當前不屬於任何MBSFN區域之載波分量(例如載波分量2)所屬之小區(例如小區3),不存在任何MBMS相關之組態資訊及與MBMS服務相關之控制平面頻道MCCH,由此連接至小區3之節點B之使用者設備,例如UE 31將無法獲得其他相鄰小區之MBMS服務資訊。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.
為此目的,根據本發明之一個較佳實施方式,訊息信元係MCCH訊息之新訊息信元,例如「neighCellMbmsInfoList」信元,來指示相鄰小區之MBMS服務資訊。藉由MCCH頻道將該信元發送至小區之使用者設備來使該使用者設備獲知相鄰小區之MBMS服務資訊。較佳地,在該新MCCH訊息信元中,可包括MBMS服務ID資訊及對應之小區ID資訊。更佳地,MBMS服務ID資訊可包括頻間相鄰小區MBMS服務ID資訊及頻內相鄰小區MBMS服務ID資訊。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.
可如下詳細定義「neighCellMbmsInfoList」信元:The "neighCellMbmsInfoList" cell can be defined in detail as follows:
進一步較佳地,對於上述較佳實施方式而言,為了使位於不提供MBMS服務之非MBSFN區域中之載波分量小區 (例如,小區3)中之使用者設備也能獲得與其所處之服務區域1中相鄰小區之MBMS服務相關之資訊並進而接收相應之MBMS服務,需要系統資訊區塊SIB13進行協作,因為在SIB13中定義了相關之MBSFN子訊框資源及MCCH組態資訊。例如,根據本發明之方法進一步包括:修改當前SIB13之定義,以便向不屬於任何MBSFN區域(亦即,不提供MBMS服務)之小區指示MCCH組態資訊,當然SIB13也可直接包含其他相鄰小區之MBMS服務相關之資訊。更具體而言,根據本發明之方法可修改SIB13之信元「MBSFN-AreaInfoList」之值範圍,使SIB13包含指示載波分量小區不屬於任何MBSFN區域之空MBSFN區域資訊清單。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.
可替換地,可在SIB13中,針對系統資訊區塊SIB13中與MBSFN區域相關之信元定義一個預設值,預設值指示載波分量小區不屬於任何MBSFN區域,其中MBSFN區域為提供MBMS服務之區域。例如,若使用者設備(例如UE 31)之當前小區(小區3)不屬於任何MBSFN區域,則將預設值發送至當前小區,使得當前小區具有MCCH頻道,從而使用者設備UE 31獲得其他相鄰載波分量之小區之MBMS服務ID之訊息信元,且根據該訊息信元,接收相應之MBMS服務。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.
根據本發明之另一較佳實施方式,可不在MCCH頻道上發送與相鄰小區之MBMS服務相關之訊息信元,而是將與相鄰小區之MBMS服務相關之訊息信元包含在系統資訊區塊中而對服務區域中之載波分量小區之使用者設備進行信 號發送。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.
