The technical field

[1] the Present invention relates to a multimedia broadcast/multicast service (MBMS", and more specifically to transmission and reception of data and control information for a multimedia broadcast/multicast service MBMS".

The level of technology

[2] Universal mobile telecommunications system UMTS is a mobile communication system of the third generation, which was the result of the evolution of global system for mobile communications "GSM", which is a European standard. The purpose of the universal mobile telecommunication system UMTS is the provision of mobile communication services of high quality on the basis of the core network of GSM and broadband multiple access code division of channels.

[3] Structure 1 network universal mobile telecommunications system UMTS is shown in figure 1. The mobile terminal or subscriber unit 2 "UE" is connected to a core network 4 "CN" through "UTRAN" - ground network 6 radio access universal mobile telecommunications system. Terrestrial radio access network from 6 "UTRAN configures (configures) channel radio access, provides support and manages data exchange between terminal 2 "UE and core network 4 and achieving the appropriate t is ebouaney to the quality of services across the end-to-end route data.

[4] Terrestrial radio access network from 6 "UTRAN" contains several subsystems 8 radio "RNS", each of which contains a single controller 10 refers to "RNC" for multiple base stations or wireless base stations 12 - "Nodes". The controller 10 refers to "RNC", connected to the base station 12, is a managing controller radio network "RNC", functioning as a distribution and control in relation to shares, issued by any number of terminals 2 "UE", working in the same cell. In the wireless base station Node has one or more cells. The main controller 10 refers to "RNC manages traffic information, controls the overload of the cells and the acceptance of a new network of radio channels. Each wireless base station 12 "Node" may receive a signal on the rising channel from terminal 2 to transmit signals on its downward channel to the terminal 2. Each wireless base station 12 "Node" serves as an access point, providing the terminal 2 can connect to terrestrial networks 6 radio access "UTRAN", and the controller 10 refers to "RNC" serves as an access point, connecting the respective base stations "Node In the" core network 4.

[5] number of radio network subsystems 8 terrestrial network 6 wireless access "UTRAN" serving radio network controller 10 "RNC" is Soboh the radio network controller "RNC", managing the allocated radio resource for the purpose of providing services to a particular terminal 2 "UE", it is the access point to the core network 4 to send data to a specific terminal "UE". All other radio network controllers 10 "RNC", connected to the terminals 2 "UE"are the drift radio network controllers "RNC", so that only one serving radio network controller "RNC" connects the terminal UE" to the underlying network 4 via terrestrial radio access network from 6 "UTRAN". The drift radio network controllers 10 "RNC" facilitate the routing of user data and distribute codes as a shared resource.

[6] the Interface between the terminal 2 "UE" and terrestrial radio access network from 6 "UTRAN" implemented by the air interface Protocol, established in accordance with the specifications of the radio access network, characterized by the physical layer (L1), the data link layer (L2) and network level (L3), described, for example, in the specifications of the "Project on cooperation with third generation 3GPP". These levels are based on the lower three levels of the model of the future interconnection of open systems (OSI), is well known in communication systems.

[7] the structure of the air interface Protocol is illustrated in figure 2. As shown, the air interface Protocol is divided horizontally at the physical layer, data link layer and network layer, and particularistically on the user plane for transmitting a data stream, such as speech signals and packet data Protocol of the Internet, and a control plane for transmitting control information for maintenance and management interface.

[8] the Physical layer (PHY) provides a service for the transmission of data to the upper level and through the transport channels associated with level access control environment "MAC". Level access control environment "MAC and the physical layer to communicate via the transport channel. In addition, through the physical channel data being transferred between different physical layers, namely, between physical layers of a transmitting side (transmitter) and a receiving side (receiver).

[9] the access control environment "MAC" second level management ensures the delivery of services in transmission of information on the upstream level and is connected via a logical channel with level control channel "RLC". Level control channel "RLC" of the second level (L2) supports reliable data transfer and can perform the functions of segmentation and concatenation (serial connection) service data units "SDU" control channel "RLC", taken from upstream level.

[10] the Level of radio resource management "RRC", located in the lower part of the third level (L3)set the n only in the control plane and manages the transport channels and physical channels in relation to institutions, reconfiguration and release of radio channels. Channel "RB" refers to the service provided with the use of lower levels, such as level control channel "RLC" or level access control environment "MAC" to transfer data between the mobile terminal UE and terrestrial radio access network from 6 "UTRAN". Usually when creating a channel determined by the control characteristics of the hierarchical level and a channel required for providing specific services to help you set the appropriate parameters and operating procedures.

[11] When creating a channel determined by the control characteristics of the hierarchical level and a channel required for providing specific services to help you set the appropriate parameters and operating procedures. When a connection is established to ensure the transfer between the level of radio resource management "RRC" specific "UE" 2 and level radio resource management "RRC" terrestrial network 6 wireless access "UTRAN", then we say that terminal 2 "UE" in the "RRC connection". In the absence of such connection terminal 2 "UE" is in a wait state.

[12] Next will be described the service is a multimedia broadcast/multicast service ("MBMS" or service "MBMS). Multimedia broadcast/multicast maintenance the lid "MBMS" is a way of supplying a stream or background services on multiple mobile terminals UE", using the downward channel is a multimedia broadcast/multicast service, which uses at least one multipoint radio links per subscriber with multiple and one channel of direct communication. One service is a multimedia broadcast/multicast service MBMS includes one or more communication sessions, and the data of the multimedia broadcast/multicast service MBMS to be transferred to more than one terminal through the radio channel multimedia broadcast/multicast service (hereinafter "channel-MBMS") only during a communication session.

[13] Service MBMS can be carried out in broadcast or multicast mode. Broadcast mode is used for transmitting multimedia data to all users 2 "UE" in the area of broadcasting, for example in areas where it is available. Multicast mode is used for transmitting multimedia data to a specific group of terminals 2 "UE" in the zone multicast, broadcast, such as in areas where available multicast service.

[14] Terrestrial radio access network from 6 "UTRAN provides the MBMS service to the terminal 2 "UE"using the radio channel "RB". The radio channels used by terrestrial radio access network from 6 "UTRAN", can be classified as direct radio with the connection (point-to-point radio channels) of the type "point-to-point or multi-point radio point - the set of points". The direct radio communication is a bidirectional radio channels and include a dedicated logical channel traffic (information channel DTCH dedicated transport channel DCH and the dedicated physical channel DPCH or channel SCCPCH"-supporting the General Manager of the physical channel.

[15] As shown in figure 3, multi-point radio point - set of points represents a unidirectional downlink channel includes a logical channel MTSN" (multipoint channel traffic multimedia broadcast/multicast service MBMS", then multimedia multipoint channel traffic MDN"), a transport channel direct access "FACH" and supporting the General Manager of the physical channel SCCPCH". Logical channel MTSN" is configured for each service "MBMS", supplied by a single cell, and is used to transmit the user plane data of a particular service "MBMS" to the set terminal "UE".

[16] figure 3 shows a diagram illustrating the mapping of channels for MBMS". According to figure 3 multipoint radio link-type point - to-multi point" includes logical multimedia multipoint channel traffic MTSN", the transport channel direct access "FACH" and supporting the General Manager of the physical channel SCCPCH". Logical channel MTSN" to figurines for each service "MBMS", we offer a single cell, and is used for transmission of user plane data services "MBMS" set terminal "UE".

[17] As shown in figure 3, the logical channel "MSN" (control channel multimedia broadcast/multicast service control channel MBMS") is a multipoint channel downlink and is used for transmitting control information of a multimedia broadcast/ multicast service MBMS". Logical channel MSN" is displayed in the transport channel direct access "FACH", and a transport channel direct access "FACH" is displayed in the subsidiary General Manager of the physical channel SCCPCH". One cell has a single logical channel "MSN".

[18] figure 4 shows a schematic diagram of data transmission on the control channel multimedia broadcast/multicast service "MSN". Information of the logical channel "MSN" is transmitted periodically in accordance with a period of change and repetition period. Information of the logical channel "MSN" is divided into critical and non-critical. The difference between critical and non-critical information is that non-critical information can be changed in the change period or in the period of repetition, and critical information can be MEAs is replaced only in the period of change. Therefore, when the transmission of critical information is repeated once during each repetition period, and transmitting the modified critical information can occur only at the beginning of the period changes.

[19] Information of the logical channel "MSN" contains one or more control messages multimedia broadcast/multicast service MBMS" (for example, message-level radio resource management "RRC", information about the changed services "MBMS" ("MSI-message"), information on an unmodified services "MBMS" ("USI-message"), information about multipoint radio "MBMS" and information about the access/information about the communication session, etc). Among these messages is considered non-critical access information (information about the communication session), and all other informational messages logical channel "MSN" are considered as critical information.

[20] Information about the communication session is used to control the measurement process. Based on the information on the communication terminal UE performs the procedure RRC connection", the procedure cell update or URA update procedure by transmitting a response message process measurements, such as response message on the "RRC connection", the message about the update of a cell or an update message "URA".

[21] Since all messages transmits terrestrial network for the access UTRAN", the message is transmitted from the transmitter identifier "MBMS"if this message contains information about a particular service. When the transmitter identifier "MBMS" is formed with the communication session identifier "MBMS" and the service ID "MBMS". For example, when you want to send information about the changed services "MBMS" - "MSI message", then "MSI" message contains the session ID connection "MBMS" together with information about the service represented by the service ID "MBMS".

[22] Terrestrial radio access network "UTRAN periodically transmits a physical channel indicator on the service notification "MBMS" - "MICH"to indicate whether the updated information of the logical channel "MSN" during the period of change. Thus, the terminal UE"seeking only a particular service "MBMS", does not accept information channels "MSN" or "MDN" until then, until the start of the session for this particular service and "MBMS". However, the terminal UE periodically receives the channel indicator on the service notification "MBMS" - "MICH". Updating information of the logical channel "MSN" refers to creating, adding, modifying and/or removing a specific item information of the logical channel "MSN".

[23] in Addition, terrestrial radio access network "UTRAN periodically transmits "MSI" message physical channel indicator notification services the e-MBMS" - "MICH"to indicate whether the updated information of the logical channel "MSN". "MSI message contains information about the IDs of all of the services that have been updated in the current cell in the period of change, and the desired operational information for the service to which you subscribe to "UE". Here, as information about the identifiers an identifier is used for the transmission of MBMS". The ID of the transmission of MBMS consists of a service identifier "MBMS", which specifies a particular service, or the ID of the transmission of MBMS consists of a service identifier "MBMS" with the communication session identifier "MBMS", which indicates a specific session of a particular service. Of the current services provided in a given cell, the ID information for services unchanged in the period of change, is passed through the "USI"messages. In this case, information about the ID of this service, an identifier is used to transfer MBMS".

[24] When a session starts, the specific services "MBMS", the radio access network "UTRAN sends a notification indicator "NI". The specified notification indicator "NI" is the indicator that provides the notification to accept the message of the logical channel "MSN" terminal "UE"seeking a particular service "MBMS". Upon receipt of the notification indicator "NI" in the channel indicator notice is Melania about the "MBMS" - "MICH" terminal "UE" takes the logical channel "MSN for a specified period changes specified by the channel "MICH". While receiving logical channel "MSN terminal UE first receives "MSI" message to determine whether the updated during the period changes required to the user "UE" service "MBMS", and then if an update exists, receives updated information of the logical channel "MSN". The terminal UE can find a list of all services provided by the current cell by receiving transmitted "MSI messages about changed services "USI message" on an unmodified services throughout the period of change.

[25] Thus, the terminal UE", wishes to receive a particular service "MBMS" using multi-point radio point - multi-point, takes on the channel MSN" information of the logical channel "MSN", which includes information on the radio channel, and, using this information, establishes a multi-point radio point - multi-point. After establishing multipoint radio terminal UE continuously receives the subsidiary General Manager of the physical channel SCCPCH", which corresponds to the channel MTSN to get specific data services "MBMS"crossing the channel "MTCN".

[26] the radio access Network "UTRAN can transmit multimedia data shirokanedai the high/multicast service MBMS" channel "MTSN in intermittent mode. In this case, as shown in figure 3, the radio access network "UTRAN periodically transmits to the terminal UE message channel planning services "MBMS" - "MSCH" auxiliary common control physical channel SCCPCH", which corresponds to the channel MTSN". The message is planning to announce the start of transmission and duration of data transmission services "MBMS", which are transmitted during one planning period. With this purpose, the radio access network "UTRAN" must inform the user "UE" period information transmission planning.

Disclosure of the invention

Technical problem

[27] As described above, at the present level terminal equipment "UE" receives data about the service after receiving the service information about services unidirectional channel. Thus, if one service subscriber data is to be retrieved about the services of multiple channels, the terminal UE performs actions accordingly to receive data services each channel after receiving the service information about the services each channel independently.

[28] Thus, when the terminal UE accepts the subscription service, the terminal UE must independently obtain official information about the services of multiple channels. This is a problem because the terminal UE" ineffective takes office in which ormatio about the services of multiple channels. So you need a way to send and receive services "MBMS in a mobile communication system in a more efficient manner.

Technical solution

[29] Thus, the present invention provides a method of transmitting MBMS services with the goal of effectively receiving services multimedia broadcast/multicast service MBMS" terminal "UE".

[30] To achieve this, the present invention provides a method of receiving multimedia services in a mobile communication system, containing the reception control information of the first unidirectional channel in a top-down control channel; receiving control information of the second unidirectional channel on this downward control channel based on the adopted control information of the first unidirectional channel; and receiving data of the second unidirectional channel in a top-down data transmission channel using the accepted management information about the second unidirectional channel.

[31] the Downward control channel may be at least one of the following channels: a control channel of a multimedia broadcast/multicast service "MSN" and the channel indicator on the service notification "MBMS" - "MICH".

[32] Downlink data channel may be at least one of the following channels: channel multimedia traffic Shirokova the nutrient/multicast service MBMS" - "MTCN and a dedicated channel traffic "DTCH".

An example of carrying out the invention

[41] One aspect of the present invention relates to the understanding of the inventors of the problems of the modern level the equipment, as described above, and those which will be explained later. Based on this understanding have been created distinctive features of the present invention.

[42] the Present invention relates to a more efficient way of sending and receiving data and control information for a multimedia broadcast/multicast service MBMS". To this end the present invention can provide a mobile communication system having a first unidirectional data channel and the second unidirectional data channel for the same services and transmitting different data streams of the same services using the first and second unidirectional channels, respectively. Consumer "UE" (i.e. mobile terminal) can effectively take the service "MBMS" by receiving the second unidirectional channel based on the first channel received through the downward control channel.

[43] the First unidirectional channel and the second unidirectional channel can provide the same service, each channel has a respectively different quality of service (QoS). In addition, the first unidirectional channel and the second unidirectional channel can transmit/receive streaming data services through a variety of shared physical channels, using different codes channels. When e is om data of the first channel and the second channel after receiving the terminal UE can be combined.

[44] the Service may be a service multimedia broadcast/multicast service MBMS and the first unidirectional channel and/or the second unidirectional channel can be a channel for MBMS".

[45] the First unidirectional channel and/or the second unidirectional channel may use point-to-point dedicated channel traffic "DTCH" (communication) or multimedia multipoint (multicast) channel traffic MTSN" for services "MBMS".

[46] the Downward control channel may represent at least one of the following channels: a control channel of a multimedia broadcast/multicast service "MSN" and the channel indicator on the service notification "MBMS" - "MICH".

[47] Although the present invention is shown implemented in the mobile communication system, such as a universal mobile telecommunication system UMTS", developed on the basis of the 3GPP standard, the present invention can also be applied in the communication system operating in accordance with other standards and specifications.

[48] the Method of transmitting and receiving control information for MBMS in accordance with one example embodiment of the invention shown in figure 5.

[49] As shown in figure 5, it can be assumed that the terminal UE already knows binding services in many channel is in, for example, the service channel 1 and channel 2, to the service of a particular user. The network may notify the UE that the service channel 1 and channel 2 are interconnected services. For example, the network may inform the user "UE", that channel 1 is designed to "UE supporting version 6 or above 3GPP (hereinafter referred to as "UE version 6")and the service channel 2 is designed for terminal UE that supports version 7 or above 3GPP (hereinafter referred to as "UE version 7"). When this terminal UE may be in an active state and for channel 1 and for channel 2, or the terminal UE may be in an active state only for channel 2.

[50] First terrestrial network UTRAN may transmit the terminal UE" information about the service channel 1 through channel indicator on the service notification "MBMS" - "MICH" (S10). After identifying the notification indicator "NI" services channel 1 channel "MICH" terminal "UE may attempt to receive information about the service on the control channel multimedia broadcast/multicast service "MSN".

[51] Terrestrial network UTRAN may transmit information about the service service channel 1 through messages Information about the changed services "MBMS" - "MSI" message on the control channel MSN" (S11). Terrestrial network UTRAN may also before the th information about the service service channel 2 by means of the message "Information about the changed services "MBMS" - "MSI message or message Information unmodified services "MBMS" - "USI message". Thus, the user UE may receive information about the service service channel" through "MSI messages or to receive information about the service service channel 2 via MSI messages" or "USI"messages.

[52] In the message with information about the access network UTRAN can transmit the necessary information of the measurement process, if for channel 1 or for services channel 2 requires the measurement process (S12). Namely network UTRAN can transmit the necessary information to process measurements for channel 1 by receiving messages with information about the access, if the service channel 1 or service channel of the service information necessary for execution of the measurement process. When this information is needed about the process of measurement may indicate the likelihood of transmission of response information about the access channel random access "RACH". This can indicate the likelihood of transmission.

[53] When a message with information on access, there is only information about the service channel 1, the network UTRAN may assign a different priority to the service channel 1 and the channel 2. For example, for terminal "UE", which takes only service channel 1, or for terminal UE, which takes only service channel 2 can be made of different settings KL the SSA services access channel random access "RACH", signature channel "RACH", the interval of the access channel RACH" and the priority of the logical channel.

[54] it is Also possible that the network "UTRAN" can function to include a message with information about the access probability coefficients and services channel 1 and for channel 2. In this case, the terminal UE can decide to give an answer for the probability factor, for which the service channel based on the capabilities of the terminal UE (for example, depending on the UE supports version 6 or 7). For example, "UE supporting version 6 or above, may send the response message to count, using a probabilistic factor for channel 1, and "UE supporting version 7 or above, may send the response message to count, using a probabilistic factor for channel 2.

[55] When you need the measurement process services channel 1 or service channel 2 from the message with information about the service, the terminal UE may transmit a response message for counting, based on the information about the measurement process for receiving services channel 1 (S13). When a response message for the calculation can include the Indicator Version" ("RI") to represent the version number of the terminal UE". In addition, if a response message for counting is a request message "RRC connection, the indicator version of "RI" can the t to be included in the request message"RRC connection or a completion message for establishing the "RRC connection". The response message for counting may also be included in the update message cell or in an update message "URA".

[56] After execution of step SI3 terrestrial network UTRAN may determine whether to use point-to-point unidirectional channel direct connection or multipoint unidirectional channel for channel 1 and for channel 2, and then may transmit information about the radio channel in the "UE" for setup (or install) a unidirectional channel (S14). Network UTRAN may provide information about the unidirectional channel on the control channel multimedia broadcast/multicast service "MSN"if the specified specific channel is multi-channel and dedicated control channel DCCH"if the specific channel is a point-to-point radio link direct link. When this terminal UE can receive information about configuring radio channels "MSN" or "DCCH". The terminal UE that supports version 6, you may only configure a channel for a service, channel 1, and the terminal UE that supports version 7 or higher, you can configure the channel for channel 1 and for channel 2. In addition, if the network UTRAN decides not to provide the service channel 2, the terminal UE that supports version 7 or higher, you can configure only radika the al for channel 1.

[57] After that, the network UTRAN can transmit data services channel 1 and services channel 2 configured for unidirectional channel (S15). Here the service channel 1 can be transmitted over channels: multimedia multipoint channel traffic MTSN" No. 1 or a dedicated channel traffic "DTCH" No. 1, depending on the type of services "MBMS" (i.e. multicast service or point-to-point service), while the service channel 2 can be transmitted over channels "MTCN" No. 2 or "DTCH" No. 2. Multimedia multipoint channel traffic MTSN" No. 1 can be displayed on the subsidiary General Manager of the physical channel SCCPCH # 1 and then transmitted, and the channel MTCN No. 2 can be displayed on the subsidiary General Manager of the physical channel SCCPCH" No. 2 and then transmitted. When version 6 terminal UE can receive data only service channel 1 to channel MTSN" or "DTCH". When version 7 or higher terminal UE can receive data only service channel 2 or merge data services channel 1 and services channel 2 after taking the services of both channels. If the network UTRAN decides not to provide the service channel 2, the terminal UE" with version 7 can only accept data services channel 1.

[58] This feature of the present invention may be implemented or used in different situations. Usually due to the individual characteristics of "UE" (i.e. mobile terminal) porealizatsii of the present invention it is necessary to consider a variety of factors, such as degree of mobility, limited CPU, limited memory constraints on the power consumption of the battery, a relatively small display screen, etc. to achieve a compromise between all of these aforementioned factors. Thus, in the present invention, the service channel 1 and channel 2 can be combined, based on the capabilities of the terminal UE". For example, if channel 1 is provided with a relatively high quality of services (for example, when the highest processing speed (saline) 192 kbit per second for audio), and in channel 2 is provided with a relatively low quality of services (for example, when the highest processing speed (saline) 64 kbit per second for audio), based on the capabilities of the terminal UE, which supports audio only at the highest processing speed of 128 kilobits per second, by combining the services of channel 1 and services channel 2 can be obtained intermediate quality (i.e. the highest processing speed 128 kbit per second for audio). Because the present invention allows to take the control information and/or data services channel 2 on the basis of control information and/or data services channel 1, then the overall quality of services may be improved, while also taking into account the capabilities of the terminal UE". This concept of bundling different quality in the field of services "MBMS" understandable for specialists in this field of technology, and the present invention can be used in different types of quality of service (i.e. the display settings, autoparametric, parameters, settings file, and so on).

[59] we Can say that the present invention provides a method of receiving multimedia services from the network by the mobile terminal, the method includes receiving control information of the first unidirectional channel through the downward control channel; receiving control information of the second unidirectional channel through the downlink control channel based on the received control information of the specified first channel; receiving data on the second unidirectional channel via top-down data channel using the accepted control information specified second channel, the decision to use the first or the second unidirectional channel based on the capabilities of the mobile terminal, when it is tried to accept the system information on the control channel multimedia broadcast/multicast service "MSN", when a mobile terminal according to the channel indicator on the service notification "MBMS" - "MICH" identifies information about the notification lights the re "NI", and receive information on access to information of the first radio channel when the required measurement process, at least one of the channels of the first unidirectional channel or the second unidirectional channel; in a specified way downward control channel is at least one of the following channels: managing the MBMS channel (MSN) and the channel indicator on the service notification "MBMS" - "MICH", downlink data channel is at least one of the following channels: channel traffic multimedia broadcast/multicast service MBMS" - "MTCN and a dedicated channel traffic "DTCH", the first unidirectional channel and the second unidirectional channel respectively have different quality of service (QoS), the first unidirectional channel and the second unidirectional channel received through a variety of common physical channels with different channel codes, the first one-way channel and the second unidirectional channel after reception are combined together, the control information of the first unidirectional channel is received by the mobile terminal through a modified service information about the changed services "MSI" control channel "MSN", the control information of the second channel is received by the mobile terminal through the information about the changed services "MSI" or through information what s on unmodified services "USI" control channel "MSN", the response to the access information includes an indicator of the version of "RI", a multimedia service is a multicast service and/or service multimedia broadcast/multicast service MBMS", the first unidirectional channel and the second unidirectional channel used in the same multicast service, the first unidirectional channel and the second unidirectional channel belong to the service channel "MBMS", the first unidirectional channel and the second unidirectional channel created in a single cell, and the access information includes a probability factor indicating the probability to transmit the response to information about the access channel random access "RACH".

[60] furthermore, the present invention can provide a method of transferring services multimedia broadcast/multicast service MBMS" from the network to the mobile terminal, the method includes sending control information of the first unidirectional channel through the downward control channel; sending control information of the second unidirectional channel through the downward control channel, where the control information of the second unidirectional channel based on the control information of the first unidirectional channel; sending to the mobile terminal, information access, where info is the information about the access contains settings for the counting procedure for the first unidirectional channel, assigning different priorities to the first unidirectional channel and the second unidirectional channel based on at least one of the following: class of service access channel RACH", the signature of the channel RACH", the interval of the access channel RACH" and the priority of the logical channel; receiving a response message count procedure, where the response message count procedure includes the indicator; determining, will be used point-to-point communication or multipoint channel for the first and/or second unidirectional channels; sending to the mobile terminal information for configuring unidirectional channel through the control channel MBMS" - (MSN if it is determined multipoint channel; sending to the mobile terminal information for configuring unidirectional communication through the dedicated control channel DCCH", if it is determined a one-point channel; sending data over the first and second unidirectional channels, at least through one of the channels: channel traffic multimedia broadcast/multicast service MBMS" - "MTCN and a dedicated channel traffic "DTCH", where the downlink control channel is at least one of the channels: a control channel of a multimedia broadcast/ multicast service "MSN and channel the notification light on the servant "MBMS" - "MICH", the control information of the first unidirectional channel is contained in the message Information about the changed MBMS services" - "MSI message in the control channel MSN", the control information of the second unidirectional channel is contained at least in one of the messages in the message "Information about the changed MBMS services" - "MSI message or message Information unmodified MBMS services" - "USI message in the control channel MSN", the process parameter measurement is a probability factor that indicates the ability to transmit the answer information on the access channel random access "RACH".
