A method and eMBMS-enabled infrastructure device are disclosed that provide an updated mechanism for a client, or user equipment (UE), to report its location such that an eMBMS-enabled application desiring eMBMS location information can uniquely identify the MBSFN in which the UE is located. The method and eMBMS-enabled infrastructure device identify an eMBMS area associated with a user equipment UE by receiving, from the UE, a Multicast Broadcast Single Frequency Network (MBSFN) Area update message from a user equipment, wherein the MBSFN Area update message uniquely identifies an MBSFN Area and includes an extension identifier derived from one or more of a cell identifier, an eNodeB identifier, an identifier of a group of cells, a service identifier, a tracking area identifier, and a paging area identifier, and optionally further may include an MBSFN AreaID, and determining an MBSFN Area serving the user equipment based on the received eMBMS area identifier.

The invention discloses a resource scheduling method, device and base station for long-term evolution system multicast broadcasting service. The method comprises the steps that the base station identifies whether the number of users meets the predetermined first broadcasting threshold condition in a predetermined cycle or in real time according to the number of the users subscribing the eMBMS service in a multicast broadcasting single frequency network (MBSFN) region; the number, meeting the first broadcasting threshold value, of the users is responded, the base station distributes multicast broadcasting subframes BMS to serve as service subframes, and a control channel comprised by the BMS contains instruction information of service data received by a user terminal through a data channel; the number, which does not meet the first broadcasting threshold value, of the users is responded, unicast subframes are distributed to serve as the service subframes, and the service data are borne; the base station inserts the service subframes in a downlink data frame sequence, and sends the data frame sequence to the user terminal in the MBSFN region. According to the technical scheme, scheduling modes of the base station can be flexibly switched between the multicast broadcasting mode and the unicast broadcasting mode, and the flexibility and the resource utilization rate of eMBMS service resource scheduling are improved.

A method and system for requesting a Physical PMCH are provided. The method includes: user equipment determines a target cell to be immigrated which is adjacent to a cell where the user equipment is located; and if the user equipment judges that a preconfigured Multicast Broadcast Single Frequency Network (MBSFN) area in the adjacent target cell does not comprise the MBSFN area used by the Multimedia Broadcast Multicast Service (MBMS) service / group call currently received by the user equipment, the user equipment requests a network side equipment to allocate a PMCH for the currently received MBMS service / group call. According to the technical solution provided in the present invention, the service continuity of the PTT communication user in a receiving state during the moving process is implemented.

The invention discloses a method and a device for transmitting multimedia broadcast and multicast service (MBMS) control data. When the MBMS control data is sent, subframes for carrying MSBM broadcast channels and synchronizing channels all adopt a method and a device for sending with a single cell, thereby avoiding the problem that UE in a cell of two multicast broadcast single frequency network (MBSFN) overlapped areas cannot determine how to deploy physical broadcast channels on the premise of guaranteeing lower sending complexity. Furthermore, physical multicast control channel (P-MCCH) is also transmitted by the subframes, thus the problem that the UE of a non-overlapped part of an area covered with overlapped MBSFN cannot receive specific MBMS data after receiving P-MCCH and secondary multicast control channel (S-MCCH) is further solved so as to reduce the complexity for sending the MBMS control data of a system under the condition of covering different MBSFN areas.

The invention discloses an information reporting / receiving method and device and a bearer establishing method and device. The information receiving method is characterized by comprising that terminal equipment sends indication information to an access network node, wherein the indication information is used for indicating that information to be reported by the terminal equipment is information to be sent on time and frequency resources corresponding to a multicast broadcast single frequency network area; the access network node requests network-side equipment to establish a service bearer for the information to be reported by the terminal equipment; the network-side equipment establishes a service bearer, wherein the service bearer comprises a wireless bearer used by the terminal equipment for reporting information to the access network node and notifying configuration information of the service bearer established by the access network node; and the access network node configures a wireless bearer for the information to be reported of the terminal equipment according to the configuration information, notifies the terminal equipment to report the information on the configured wireless bearer, and receives the information reported by the terminal equipment on the configured wireless bearer. According to the invention, the terminal equipment receives a notification; and information is collected, and the information is reported on the wireless bearer according to the configuration information. By adopting the method and device disclosed by the invention, requirements of services having specific requirements for time delay can be met.

The invention discloses a method, a system and a device for transmitting an enhanced type multimedia broadcast multicast service (EMBMS), which are applied to improving the EMBMS receiving quality of a user terminal. A method for receiving the EMBMS is applied to the process of receiving the EMBMS by the user terminal in an idle state by using multi-cell point-to-multipoint mode resources in a multicast broadcast single frequency network, and comprises the following steps that: the user terminal sends an EMBMS request message to a network side; the user terminal receives configuration information of single-cell point-to-multipoint mode resources established by the network side for transmitting the EMBMS; and the user terminal acquires the new resources allocated by the network side for transmitting the EMBMS, and uses the resources to receive the EMBMS. The method, the system and the device are mainly applied to transmitting and receiving the EMBMS in the multicast broadcast single frequency network, improving the EMBMS receiving quality, and ensuring the EMBMS receiving continuity.

The invention discloses a method and system for realizing MBMS (Multimedia Broadcast Multicast Service) service scheduling. The method comprises the following steps of: setting a scheduling condition in a scheduling network element; and scheduling the multimedia broadcast multicast service (MBMS) service by taking a cell in a multicast broadcast single frequency network (MBSFN) region as an object according to the scheduling condition. According to the method, the MBMS service scheduling by taking the cell in the MBSFN region as an object is realized, and transmission of the MBMS service in the cell is prevented from being closed in a cell where no user receives the MBMS service, or when the number of users receiving the MBMS service in the cell is lower than a threshold, so that the utilization ratio of wireless resources is increased, and waste of transmission power is avoided.
