Description

Method for informing multimedia broadcast/multicast service radio bearer configuration parameters

The present invention relates to a multimedia broadcast/multicast service (MBMS) implementation technique, and more particularly to a method for notifying MBMS service radio bearer (RB) configuration parameters. Background of the invention

Multicast and broadcast are technologies that transfer data from one data source to multiple destinations. In a conventional mobile network, a cell broadcast service (CBS: Cell Broadcast Service) allows low-bit rate data to be transmitted to all users through a cell shared broadcast channel, which belongs to a message type service.

Nowadays, the demand for mobile communication is no longer satisfied with the telephone and message services. With the rapid development of the Internet, a large number of multimedia services have emerged. Some of these application services require multiple users to receive the same data at the same time, such as video on demand, TV. Broadcast, video conferencing, online education, interactive games, etc. Compared with general data, these mobile multimedia services are characterized by large data volume, long duration, and delay sensitivity. The current IP multicast technology is only applicable to wired IP networks, not to mobile networks, because mobile networks have specific network structures, functional entities, and wireless interfaces, which are different from wired IP networks.

In order to effectively utilize mobile network resources, WCDMA/GSM Global Standards Organization 3GPP proposes multicast and broadcast services (MBMS), which provides a point-to-multipoint service in which data sources send data to multiple users in a mobile network, realizing network resources. Sharing, improve the utilization of network resources, especially the air interface resources. MBMS defined by 3GPP can not only achieve low-speed message-like multicast and broadcast in pure text, but also realize multicast and broadcast of high-speed multimedia services, which undoubtedly conforms to the trend of future mobile data development.

The structural model of the MBMS business system is shown in Figure 1. In order to support the MBMS service, a mobile network function entity has been added. The broadcast multicast service center BM-SC is a content provider. The entry, for authorizing and initiating the MBMS bearer service in the mobile network, and transmitting the MBMS content according to a predetermined time schedule. In addition, User Equipment (UE), Universal Terrestrial Radio Access Network (UTRAN), GSM EDGE Radio Access Network (GARAN), Serving GPRS (Serving GPRS) Support Node, SGSN), Gateway GPRS Support Node (GGSN) and other functional entities are enhanced to add MBMS-related functions.

MBMS includes multicast mode and broadcast mode. The multicast mode requires the user to subscribe to the corresponding multicast group, perform service activation, and generate corresponding accounting information. Because the multicast and broadcast modes differ in business requirements, their business processes are different.

The MBMS service has two modes when transmitting between UTRAN and UE: Point-to-Multipoint (PTM) mode and Point-to-Point (PTP) mode. The PTM mode transmits the same data through the MBMS point-to-multipoint traffic channel (MTCH) logical channel, and all UEs that join the multicast service or are interested in the broadcast service can receive the PTP mode through the dedicated mode. The Dedicated Channel (DTCH) logical channel transmits data, and only one corresponding UE can receive it.

The specific process for a user to receive an MBMS multicast service is as follows:

1. User subscription (Subscription): Establish a connection between the user and the service provider;

2. Service announcement: informs the user of the relevant information of the MBMS service;

3, join (joining): The user informs the network to prepare to receive the MBMS service;

4, Session Start (Session Start): BM-SC is ready to send data;

5, MBMS Notification: RNC informs the user of MBMS multicast data transmission;

6, the data transmission process; 7. Session Stop: The BM-SC is not ready to send data, and the bearer resources can be released.

8. leaving: The user is no longer a member of the MBMS multicast group.

In the MBMS multicast service flow, the two steps of user join and session start are independent, that is, a user may join a multicast service before the session starts or during the session after the session starts.

The MBMS Point-to-Multipoint Control Channel (MCCH) is a channel for transmitting MBMS control information. The contents include at least: MBMS SERVICE INFORMATION, MBMS RADIO BEARER INFORMATION, MBMS NEIGHBORING CELL INFORMATION, and the like.

Before the user receives the MBMS data and ends the data reception, the RNC informs the user that the radio bearer configuration parameter and the radio bearer configuration parameter change are notified to the user when receiving the MBMS service.

The steps for notifying the user of the MBMS service radio bearer parameters in the current protocol are as follows:

1. After receiving the Session Start indication from a certain MBMS service of the CN, the UTRAN performs a User Counting process as needed.

2. According to the result of Counting, the UTRAN determines whether to adopt the PTM bearer mode or the PTP bearer mode.

3. If the UTRAN decides to use the PTM mode, the UTRAN configures the radio bearer configuration parameters related to the service and updates the corresponding information on the MCCH: MBMS SERVICE INFORMATION and MBMS RADIO BEARER INFORMATION, and updates the MBMS service identifier (MBMS) in the information. Identity, MBMS ID) and PTM information of the MBMS service.

31. Discontinuous Reception (DRX) wakeu State, UE and CELL-FACH in idle state, CELL-PCH and URA-PCH read MBMS Notification (MBMS Notification, MBMS NI), if MBMS NI is detected, read MCCH at preset time to obtain RB Configure MBMS service control information for parameter information.

After receiving the MBMS service information and the configuration parameter information, the UE may receive the MBMS service by using the RB configuration parameter information indicated on the MCCH.

4. If the UTRAN decides to use the PTP mode, the UTRAN will use the traditional paging mechanism to notify the UE in the CELL-PCH state to perform cell update, or notify the UE in the Idle state to establish an RRC connection, and further UTRAN through an RRC procedure such as an RB setup procedure. Establish a PTP RB.

41. The UE establishes a PTP RB bearer by using an RRC procedure selected by the UTRAN.

5. UTRAN Update The MBMS SERVICE INFORMATION on the MCCH informs the MBMS service control information associated with the user who newly joined or just entered the cell.

The problems with the prior art are:

For each MBMS service with a determined bearer mode, the RB configuration parameter information of the service needs to be notified by the MCCH.

The protocol specifies a large number of RB configuration parameter information to be transmitted, such as: information of physical channels of each logical channel, frequency information, activation time information for enabling the configuration, core network (CN) information, and some default information.

That is to say, the amount of information of the RB configuration parameter information that needs to be transmitted on the MCCH channel is relatively large, so that it has a very serious resource occupation for the MCCH with limited capacity. According to the existing protocol, even if several MBMS services use a combination of configuration parameters, they must be sent multiple times, which is a waste of MCCH resources and air interface resources.

The MCCH is the only control information channel for all MBMS services, so there is a lot of control information to be carried. If you can reduce the configuration parameters that need to be transmitted on the MCCH, The amount of information, then it will be very beneficial to reduce the data reception error caused by the transmission configuration parameter error, and also reduce the amount of information transmitted by the air interface. Summary of the invention

In view of this, the main object of the present invention is to provide a plurality of methods for notifying MBMS Service Radio Bearer (RB) configuration parameters to effectively reduce the amount of information transmitted on the MCCH channel.

Although the MBMS service is very rich, its Quality of Service (QoS) type is relatively small. From the current R6 agreement, in terms of the big aspect, there are only two types of services, streaming and background. The transport channel used in the actual transmission of the MBMS service: Forward Access Channel (FACH) and physical channel: The number of Secondary Common Control Physical Channel (SCCPCH) is also limited, which can be said to be actually available. The RB configuration parameter combination is relatively small compared to the rich MBMS service.

Therefore, it is perfectly possible to identify or classify these limited configuration parameters, and broadcast correspondingly on the broadcast channel and the MCCH channel, effectively reducing the amount of information transmitted on the MCCH channel. Accordingly, the present invention provides the following four methods for notifying the MBMS service radio bearer configuration parameters:

The first method for notifying the MBMS service radio bearer configuration parameter provided by the present invention is to set a corresponding identifier for each RB configuration parameter combination information for the MBMS service; the method further includes the following steps:

A. periodically broadcast the RB configuration parameter combination information and the corresponding identifier on the cell broadcast channel BCH;

After the network side determines to transmit the MBMS service, select a configuration parameter combination, and broadcast the corresponding identifier of the selected configuration parameter combination in the MBMS control channel MCCH; or send the selected configuration parameter to the UE through the Paging or DCCH dedicated channel. Combined correspondence Identification

C. The user equipment UE with the MBMS service function obtains the configuration parameter combination information and the corresponding identifier from the BCH; and receives the identifier of the configuration parameter combination used by the current MBMS service from the MCCH, or receives through the Paging or DCCH dedicated channel. The identifier of the configuration parameter combination used by the current MBMS service, and the RB configuration parameter used by the current MBMS service is obtained according to the configuration parameter combination information corresponding to the identifier in the BCH.

If the UE crosses the neighboring cell from the local cell, if the configuration parameter combination used by the same MBMS service of the neighboring cell is one of the current multiple MBMS service configuration parameter combinations of the current cell, the neighboring cell RB configuration parameter in the MCCH channel is used. Only the identification information corresponding to the configuration parameter in the local cell is broadcasted. Otherwise, the configuration parameter combination information used by the neighboring cell for the MBMS service is broadcasted in the neighboring cell RB configuration parameter in the MCCH channel.

The BCH uses the SIB type newly defined by the network side to broadcast configuration parameter combination information for the MBMS service. The new SIB type has multiple occurrences, and each occurrence corresponds to a combination of configuration parameters, and the corresponding corresponding to the occurrence is broadcasted in the BCH. Occurrence id identifier;

The MCCH channel only needs to broadcast the occurrence id identifier corresponding to the selected configuration parameter combination.

In the step C, the UE obtains the occurrence id information corresponding to the current MBMS service from the MCCH channel, and combines the configuration parameter combination information corresponding to the occurrence id in the broadcast channel to obtain the configuration parameter used by the current MBMS service.

The BCH broadcasts the configuration parameter combination information for the MBMS service by using an SIB type in the existing protocol; and each of the SIB types corresponds to a configuration parameter combination, and the occurrence ratio is broadcasted in the broadcast channel. The occurrence id identifier; only the occurrence id identifier corresponding to the selected configuration parameter combination is broadcasted in the MCCH channel; In the step C, the UE obtains the occurrence id information corresponding to the current MBMS service from the MCCH channel, and combines the configuration parameter combination information corresponding to the occurrence id in the broadcast channel to obtain the configuration parameter used by the current MBMS service.

The SIB type in the existing protocol is SIB16.

If the UE enters the neighboring cell from the local cell, if the configuration parameter combination used by the same MBMS service of the neighboring cell is one of the current multiple MBMS service configuration parameter combinations of the current cell, the configuration parameter combination is simultaneously broadcasted in the MCCH channel. The corresponding occurrence id information of the local cell, otherwise, the configuration parameter combination information used by the neighboring cell for the MBMS service is broadcasted in the MCCH channel.

The period of each occurrence is predetermined by the RRC based on the frequency of use of the combination of configuration parameters used by the various MBMS services broadcast on the current broadcast channel.

When the RB configuration parameter of the current MBMS service is changed, and the changed RB configuration parameter has been set with the corresponding occurrence id, the network side will notify the UE through the MCCH channel by the occurrence id corresponding to the changed configuration information, and the UE receives the MCCH channel. After the notification information, the modified configuration parameters used by the MBMS service are obtained according to the configuration parameter combination information corresponding to the identifier in the BCH.

When the RB configuration parameter of the current MBMS service is changed, and the corresponding VR configuration parameter combination is not set with the corresponding occurrence id, the network side sets the corresponding occurrence id for the RB configuration parameter combination, and modifies the corresponding configuration information on the broadcast channel. The RB configuration parameter combination setting and the corresponding occurrence id are sent to the UE in the BCH; and the occurrence id corresponding to the changed configuration information is notified to the UE through the MCCH channel;

After receiving the notification information of the MCCH channel, the UE receives the configuration parameter combination information corresponding to the occurrence id in the broadcast channel, and obtains the modified configuration parameter used by the MBMS service.

When the RB configuration parameters of the current MBMS service change, and the changed RB configuration The parameter combination adopts an occurrence id corresponding to the change; the corresponding configuration information on the broadcast channel is modified, and the new RB configuration parameter combination information corresponding to the occurrence id is sent to the UE in the BCH;

After receiving the notification information of the MCCH channel, the UE receives the configuration parameter combination information corresponding to the occurrence in the broadcast channel, and obtains the modified configuration parameter used by the MBMS service.

When the configuration parameter of the current MBMS service is changed, and the corresponding advertised id is set in the changed RB configuration parameter, the RRC will notify the UE of the occurrence id corresponding to the changed configuration parameter information through the Paging or DCCH dedicated channel.

If the changed RB configuration parameter combination does not set the corresponding occurrence id, the RRC notifies the UE of the occurrence id corresponding to the changed configuration parameter information through the Paging or DCCH dedicated channel; and simultaneously modifies the corresponding configuration parameter information on the broadcast channel; After the notification information is received, the configuration parameter information corresponding to the occurrence id in the broadcast channel is received again, and the modified configuration parameter used by the MBMS service is obtained.

When the configuration parameters of the current MBMS service change, the MCCH channel sends the changed configuration parameters to the UE, and the UE directly receives the changed configuration parameters from the MCCH channel.

If the corresponding occurrence id is not set in the RB configuration parameter combination after the configuration parameter of the current MBMS service is changed, the network side further sets the corresponding oc ence id for the RB configuration parameter combination, and modifies the corresponding configuration information on the crowded channel, and the RB is modified. The configuration parameter combination information and the corresponding occurrence id are sent to the UE on the BCH.

The second method for notifying the MBMS service radio bearer configuration parameter provided by the present invention, the RB common configuration parameter for the MBMS service is configured as a default configuration in the protocol, and is a RB non-public configuration parameter for the MBMS service. The combined information sets the corresponding identifier; the method further includes the following steps:

A. periodically broadcasting the RB non-public configuration parameter combination on the cell broadcast channel BCH Information and corresponding identification;

B. After the network side determines to transmit the MBMS service, select a non-common configuration parameter combination, and broadcast the corresponding identifier of the selected non-public configuration parameter combination in the MBMS control channel MCCH; or send the UE to the UE through the Paging or DCCH dedicated channel. Corresponding identifier of the selected configuration parameter combination;

C. The UE with the MBMS service function obtains the non-common configuration parameter combination information and the corresponding identifier from the BCH; and receives the identifier of the configuration parameter combination used by the current MBMS service from the MCCH, or receives through the Paging or DCCH dedicated channel. The RB configuration parameter used by the current MBMS service is obtained according to the non-common configuration parameter combination information corresponding to the identifier in the BCH.

If the UE crosses the neighboring cell from the local cell, if the non-common configuration parameter combination used by the same MBMS service of the neighboring cell is one of the current multiple MBMS service non-public configuration parameter combinations of the current cell, the neighboring cell in the MCCH channel The RB configuration parameter only broadcasts the identification information corresponding to the non-common configuration parameter in the local cell. Otherwise, the neighboring cell RB configuration parameter in the MCCH channel is used to broadcast the non-public configuration parameter group of the neighboring cell for the MBMS service.

The BCH broadcasts the non-public configuration parameter combination information for the MBMS service by using the newly defined SIB type on the network side; the new SIB type has multiple occurrences, and each occurrence corresponds to a non-public configuration parameter combination, and is broadcast in the BCH. The occurrence id identifier corresponding to the occurrence;

The MCCH channel only needs to broadcast the occurrence id identifier corresponding to the selected non-public configuration parameter combination;

In the step C, the UE obtains the occurrence id information corresponding to the current MBMS service from the MCCH channel, and according to the non-public allocation corresponding to the occurrence id in the broadcast channel. The parameter combination information is combined with the common configuration parameters that are solidified in the protocol to obtain the complete configuration parameters used by the current MBMS service.

The BCH broadcasts non-public configuration parameter combination information for the MBMS service by using one of the existing SIB types; and causes each occurrence of the non-common configuration parameter in the SIB type to be combined in the broadcast channel. Broadcast the occurrence id identifier corresponding to the occurrence;

Only the occurrence id identifier corresponding to the selected non-public configuration parameter combination is broadcasted in the MCCH channel;

In the step C, the UE obtains the occurrence id information corresponding to the current MBMS service from the MCCH channel, and combines the non-public configuration parameter combination information corresponding to the occurrence id in the broadcast channel, and combines the common configuration parameters in the protocol to obtain the current MBMS. The complete configuration parameters used by the business.

The SIB type in the existing protocol is SIB16.

If the UE traverses the neighboring cell from the local cell, if the non-common configuration parameter combination used by the same MBMS service of the neighboring cell is one of the current multiple non-common configuration parameter combinations of the MBMS service, the UE simultaneously broadcasts the MCCH channel. The non-common configuration parameter combines the corresponding oc identification of the occurrence id in the local cell. Otherwise, the non-common configuration parameter combination information of the neighboring cell for the MBMS service is broadcasted in the MCCH channel.

The period of each occurrence is predetermined by the RRC based on the frequency of use of the non-common configuration parameter combination used by the various MBMS services broadcast on the current broadcast channel.

When the RB non-common configuration parameter of the current MBMS service is changed, and the changed RB non-public configuration parameter has the corresponding occurrence id, the network side will notify the UE of the occurrence id corresponding to the non-public configuration information that changes. After receiving the notification information of the MCCH channel, the UE obtains the modified non-public configuration parameter used by the MBMS service according to the non-public configuration parameter combination information corresponding to the identifier in the BCH. When the RB non-public configuration parameter of the current MBMS service is changed, and the changed RB non-common configuration parameter combination is not set with the corresponding occurrence id, the network side sets the corresponding oc ence id for the RB non-common configuration parameter combination, and changes the broadcast channel. Corresponding non-common configuration information, the RB non-common configuration parameter combination setting and the corresponding occurrence id are sent to the UE in the BCH; and the occurrence id corresponding to the changed non-public configuration information is notified to the UE through the MCCH channel;

After receiving the notification information of the MCCH channel, the UE receives the non-public configuration parameter combination information corresponding to the occurrence id in the broadcast channel, and obtains the modified non-public configuration parameter used by the MBMS service.

When the current RB non-public configuration parameters of the MBMS service change, and the changed

The RB non-common configuration parameter combination uses the occurrence id corresponding to the change; the corresponding configuration information on the broadcast channel is modified, and the new RB non-common configuration parameter combination information corresponding to the occurrence id is sent to the UE in the BCH;

After receiving the notification information of the MCCH channel, the UE receives the non-public configuration parameter combination information corresponding to the occurrence id in the broadcast channel again, and obtains the modified configuration parameter used by the MBMS service.

When the configuration parameter of the current MBMS service is changed, and the changed RB non-public configuration parameter has the corresponding occurrence id, the RRC will notify the UE of the occurrence id corresponding to the non-public configuration information that has changed through the Paging or DCCH dedicated channel; If the changed RB non-common configuration parameter combination is not set with the corresponding occurrence id, the |U RRC notifies the UE corresponding to the occurrence id corresponding to the non-common configuration information that is changed through the Paging or DCCH dedicated channel; and simultaneously modifies the corresponding non-distribution on the broadcast channel Public configuration parameter information; after receiving the notification information, the UE receives the non-public configuration parameter information corresponding to the occurrence id in the broadcast channel, and obtains the modified configuration parameter used by the MBMS service. When the non-public configuration parameter of the current MBMS service changes, the MCCH channel sends a changed non-public configuration parameter to the UE, and the UE directly receives the changed non-public configuration parameter from the MCCH channel.

If the corresponding occurrence id is not set in the RB non-public configuration parameter combination after the non-public configuration parameter of the current MBMS service is changed, the network further sets a corresponding oc ence id for the RB non-common configuration parameter combination, and modifies the corresponding non-distribution on the broadcast channel. The public configuration information is sent to the UE in the BCH by using the RB non-common configuration parameter combination information and the corresponding occurrence id.

The third method for notifying the radio bearer configuration parameter of the MBMS service provided by the present invention includes:

A. The network side broadcasts the RB common configuration parameters of the MBMS service on the BCH periodically;

B. After determining that the MBMS service is transmitted, the network side determines the configuration parameter of the MBMS service, and broadcasts the MBMS service to the UE in the MCCH; or sends the non-public configuration parameter used by the current MBMS service through the Paging or DCCH dedicated channel;

C. The public configuration parameter obtained by the UE having the MBMS service function from the BCH is used to receive the current MBMS service from the MCCH by using the non-public configuration parameter used for receiving the current MBMS service from the MCCH or using the Paging or DCCH dedicated channel. The non-public configuration parameters are combined to obtain the RB configuration parameters used by the current MBMS service.

The method for informing the MBMS service radio bearer configuration parameter provided by the present invention includes: solidifying the RB common configuration parameter for the MBMS service as a default configuration in the protocol, the method further comprising the following steps:

A. After determining the MBMS service, the network side determines the configuration parameters of the MBMS service, and broadcasts the non-public configuration parameters to the UE in the MCCH; or sends the non-public configuration parameters used by the current MBMS service through the Paging or DCCH dedicated channel. ;

B. The UE with the MBMS service function receives the current MBMS service from the MCCH. The non-public configuration parameters used, or the non-public configuration parameters used by the current MBMS service are received through the Paging or DCCH dedicated channel, and combined with the RB common configuration parameters that are solidified in the protocol to obtain the RB configuration parameters used by the current MBMS service. .

It can be seen from the foregoing technical solutions that the four methods for notifying the radio bearer configuration parameters of the MBMS service of the present invention are reduced by sending the identifier of the RB configuration parameter only on the MCCH channel, or sending the non-public RB configuration parameter information only in the MCCH. The amount of information of the RB configuration parameters transmitted by the MCCH channel, and is advantageous for reducing RB configuration parameter transmission errors and resulting data reception errors.

Mode for carrying out the invention

In order to make the objects, technical solutions and advantages of the present invention more clear, the following describes the four methods for notifying the radio bearer configuration parameters of the MBMS service provided by the present invention with reference to the accompanying drawings.

The first method for notifying the MBMS service radio bearer configuration parameter is: setting a corresponding identifier for each RB configuration parameter combination information used for the MBMS service; the method further includes the following steps:

A. periodically broadcasting the RB configuration parameter combination information and the corresponding identifier on the cell broadcast channel BCH; After the network side determines to transmit the MBMS service, select a configuration parameter combination, and broadcast the corresponding identifier of the selected configuration parameter combination in the MBMS control channel MCCH; or send the selected configuration parameter to the UE through the Paging or DCCH dedicated channel. Corresponding identifier of the combination;

The first preferred embodiment of the present invention employs the first method of the present invention. In this embodiment, the network side sets a corresponding identifier for each RB configuration parameter combination information for the MBMS service in advance, and stores it in the UTRAN.

Referring to FIG. 2, FIG. 2 is a flow chart of transmitting RB configuration parameters in a first preferred embodiment of the present invention. The process includes the following steps:

Step 200: The UTRAN periodically broadcasts RB configuration parameter combination information and corresponding identifiers for the MBMS service on the BCH channel. After receiving the RB configuration parameter combination information and the corresponding identifier, the UE records. The UE may update the recorded RB configuration parameter combination information and the corresponding identifier after receiving the information, or may update the recorded RB configuration parameter combination information and the corresponding identifier when the information changes.

The broadcast here is that the network side combines in advance according to possible RB configuration parameters, and sets corresponding identifiers for each combination. Of course, in practical applications, some RB configuration parameters may change; when the RB configuration parameters themselves do not change, the combination of configuration parameters may also be reorganized. In this case, if some parameters in the RB configuration parameter combination are changed during the execution of the MBMS service, the network side may also modify the changed RB configuration parameter in the RB configuration parameter combination, and may configure the RB for the modified parameter. The parameter combination sets a new identifier, You can also keep the original logo, you need to notify the user when using the original logo;

During the MBMS service process, the configuration parameters are reorganized. The network side can set the corresponding identifier for the new RB configuration parameter combination, or use the original identifier. However, the user needs to be notified to receive the new RB configuration parameter combination information corresponding to the identifier.

The configuration parameter combination information may include wireless configuration bearer information and/or transmission channel configuration information and/or physical channel configuration information.

When the BCH broadcasts the configuration parameter combination information of the MBMS, the existing SIB type, such as the SIB16, may be used. However, this method may affect the existing UEs without the MBMS function. To avoid affecting these UEs, the network may also be in the network. A new MBMS-specific SIB is added to the side, which is conveniently identified as SIBmbms for description. The characteristics of this SIBmbms are the same as the existing SIB16, which uses multiple occurrence methods. The occurrence is identified by an occurrence id, and each configuration parameter combination corresponds to an occurrence id, and the configuration parameter combination information used by any MBMS service of the cell can be read from an occurrence in the SIBmbms.

The period of each occurrence is determined in advance by the radio resource control entity (RRC) in the RNC in the UTi based on the frequency of use of the configuration parameter combination used by the various MBMS services broadcast on the current broadcast channel.

Step 201: The UTRAN receives the MBMS session start indication sent by the core network, and performs step 202.

In step 202, the user counting process is performed, and the radio bearer mode of the MBMS service is determined. If the MBMS service adopts the PTP bearer mode, step 203 is performed. If the MBMS service adopts the PTM bearer mode, step 204 is performed.

Step 203: Establish a PTP RB with the UE, and end the process.

Step 204: The RC selects a suitable configuration parameter combination information from the stored configuration parameter combination information, and finds a corresponding identifier. The identifier in this embodiment may be an occurrence Ido In this step, the RRC can select the appropriate configuration parameter combination information according to the parameters that need to be configured for the current MBMS service.

Step 205: Send an identifier corresponding to the R configuration parameter combination information on the MCCH channel. That is, only the occurrence id corresponding to the configuration parameter combination used by the MBMS service is broadcast in the MCCH.

Step 206: The UE receives the identifier, and obtains corresponding RB configuration parameter combination information according to the record received from the BCH, as the RB configuration parameter of the current MBMS service. In this step, the corresponding RB configuration parameter combination information can be found according to the occurrence id.

Applying the foregoing steps, the UE can obtain the RB configuration parameter of the MBMS service by receiving the broadcast channel and the MCCH, and then can use the RB configuration according to the RB configuration parameter at the specified activation time, and receive the MBMS service when the service starts to be provided.

In this embodiment, if the UE crosses the neighboring cell from the local cell, if the configuration parameter combination used by the same MBMS service of the neighboring cell is one of the current multiple MBMS service configuration parameter combinations of the current cell, the UE simultaneously broadcasts in the MCCH channel. The configuration parameter combines the identification information corresponding to the current cell, otherwise, the configuration parameter combination information used by the neighboring cell for the MBMS service is broadcasted in the MCCH channel.

Specifically, if the BCH broadcasts the MBMS configuration, the SIB type is used, and if the neighboring cell uses one of the configuration modes of the cell, the MBMS NEIGHBORING CELL is used. In PTM RB INFORMATION, only the relationship id information corresponding to the configuration mode is broadcast, instead of all the configuration parameters. If the neighboring cell uses a configuration different from the local cell, all the configuration parameters are broadcast in the MBMS NEIGHBORING CELL PTM RB INFORMATION. information. If the neighboring cell uses the same identification information for the same configuration, no repeat broadcast is required in the MCCH channel.

In fact, during the MBMS service transmission, the network side may change the MBMS. RB configuration parameters of the service. If the R configuration parameter group used by the current MBMS service changes, and the changed RB configuration parameter has the corresponding occurrence id, the network side will notify the UE through the MCCH channel, and the UE will receive the corresponding occurrence id. After the notification information of the MCCH channel is obtained, the modified configuration parameter used by the MBMS service is obtained according to the configuration parameter combination information corresponding to the identifier in the BCH.

If the RB configuration parameter is changed, and the corresponding occurrence id is not set, the network side first sets the corresponding occurrence id for the RB configuration parameter combination, modifies the corresponding configuration information on the broadcast channel, and combines the RB configuration parameters. The information and the corresponding occurrence id are sent to the UE in the BCH; and the occurrence id corresponding to the changed configuration information is notified to the UE through the MCCH channel;

After receiving the notification information of the MCCH channel, the UE receives the configuration parameter combination information corresponding to the occurrence id in the broadcast channel again, and obtains the modified configuration parameter used by the MBMS service.

Of course, if the RB configuration parameters of the current MBMS service change, the network side can directly send the changed configuration parameters to the UE in the MBMS COMMON PTM RB INFORMATIO and MBMS CURRENT CELL PTM RB INFOUMATION of the MCCH channel. In this way, the UE does not need to re-receive the corresponding information on the BCH, and can directly receive the changed configuration parameters from the MCCH channel. This method is suitable for situations where the RB configuration parameters change less.

In this case, if the corresponding RB configuration parameter combination is not set with the corresponding occurrence id, the network side may further set a corresponding occurrence id for the RB configuration parameter combination, modify the corresponding configuration information on the broadcast channel, and configure the RB. The parameter combination setting and the corresponding occurrence id are sent to the UE on the BCH.

When the RB configuration parameter of the current MBMS service changes, and the changed RB configuration parameter combination adopts the corresponding ocence id before the change; then the corresponding allocation on the broadcast channel is modified. Set the information, and send the new RB configuration parameter combination information corresponding to the occurrence id to the UE in the BCH;

In addition, for the UE in the PTP connection to receive other updated RB configuration parameter information notifications, the following methods may be used:

In the PTP mode, the network side also sends configuration parameter combination information and its corresponding identifier on the BCH channel, and sends the identifier through the Paging or DCCH channel. During the establishment of the RB, the UE receives the identifier through the Paging or DCCH channel, and obtains configuration parameters used by the MBMS service according to the information received from the BCH channel.

The second method for notifying the MBMS service radio bearer configuration parameter of the present invention is: solidifying the RB common configuration parameter for the MBMS service as a default configuration in the protocol, and is a variety of RB non-public configuration parameters for the MBMS service. The combined information sets the corresponding identifier; the method further includes the following steps:

A. periodically broadcasting the RB non-public configuration parameter combination information and the corresponding identifier on the cell broadcast channel BCH; B. After the network side determines to transmit the MBMS service, select a non-common configuration parameter combination, and broadcast the corresponding identifier of the selected non-public configuration parameter combination in the MBMS control channel MCCH; or send the UE to the UE through the Paging or DCCH dedicated channel. Corresponding identifier of the selected configuration parameter combination;

The second preferred embodiment of the present invention employs the second method of the present invention. In this embodiment, the RB common configuration parameter for the MBMS service is configured as a default configuration in the protocol, and the RB common configuration parameters of the MBMS service may be stored in advance on the network side and the UE, and are various RBs for the MBMS service. The non-public configuration parameter combination information sets the corresponding identifier.

Which configuration parameters are RB common configuration parameters, which are RB non-public configuration parameters, are determined by the system, for example: The system determines that all MBMS services have the same CN information, the same frequency information is used, and of course some default information is The same, then the CN information, frequency information, and default information can be determined as RB common configuration parameters, and other configuration parameters can be RB non-public configuration parameters. These cured RB configuration parameters can also be changed through the entire reconfiguration process of the network.

Referring to FIG. 3, FIG. 3 is a flow chart of transmitting RB configuration parameters in a second preferred embodiment of the present invention. The process includes the following steps:

Step 300: The UTRAN periodically broadcasts RB non-common configuration parameter combination information and corresponding identifiers for the MBMS service on the BCH channel. After receiving the RB configuration parameter combination information and the corresponding identifier, the UE records. The UE can update the record every time the information is received. The RB configuration parameter combination information and the corresponding identifier may also update the recorded RB configuration parameter combination information and the corresponding identifier when the information changes.

This step is basically the same as the step 200 in the first preferred embodiment, except that the broadcast is not all RB configuration parameter combination information and the corresponding identifier, but the RB non-common configuration parameter combination information and the corresponding identifier. As in the first preferred embodiment, when the BCH broadcasts the RB non-common configuration parameter combination information of the MBMS, the existing SIB type, such as the SIB16, may be used, or the newly added SIB type may be used, and the specific method and the first preferred method are used. The embodiment is the same and will not be repeated here.

Step 301: The UTRAN receives the MBMS session start indication sent by the core network, and performs step 302.

Step 302: Perform a user counting process, and determine a radio bearer mode of the MBMS service. If the MBMS service adopts the PTP bearer mode, step 303 is performed. If the MBMS service adopts the PTM bearer mode, step 304 is performed.

Step 303: Establish a PTP RB with the UE, and end the process.

Step 304: The RRC selects a suitable configuration parameter combination information from the stored non-public configuration parameter combination information, and finds a corresponding identifier. The identifier in this embodiment may be an occurrence id. In this step, the RRC may select suitable configuration parameter combination information according to parameters that need to be configured for the current MBMS service.

Step 305: Send an identifier corresponding to the RB non-common configuration parameter combination information on the MCCH channel. That is, only the occurrence id corresponding to the non-public configuration parameter combination used by the MBMS service is broadcast in the MCCH.

Step 306: The UE receives the identifier, and obtains the corresponding RB non-common configuration parameter combination information according to the record received from the BCH, and combines it with the public configuration parameter that is solidified in the protocol, as the RB configuration parameter of the current MBMS service. In this step, the corresponding RB configuration parameter combination information can be found according to the occurrence id. Applying the foregoing steps, the UE can obtain the RB configuration parameter of the MBMS service by receiving the broadcast channel and the MCCH, and then can use the RB configuration according to the RB configuration parameter at the specified activation time, and receive the MBMS service when the service starts to be provided.

Similar to the first preferred embodiment, in this embodiment, if the UE crosses the neighboring cell from the local cell, if the non-common configuration parameter combination used by the same MBMS service of the neighboring cell is the current multiple MBMS services of the cell are not public. If one of the configuration parameter combinations is used, the non-common configuration parameter combination in the MCCH channel is simultaneously broadcasted, and the non-common configuration parameter combination information of the neighboring cell for the MBMS service is broadcasted in the MCCH channel. If the BCH broadcasts the MBMS configuration, the SIB type is used. For the mobile process of the UE across the cell, if the same service of the neighboring cell uses one of the configuration modes of the current cell, the MBMS neighbor information (MBMS NEIGHBORING CELL PTM RB) The information in the INFORMATION broadcast corresponds to the context id information of the corresponding configuration mode, instead of all the configuration parameters. If the neighboring cell uses a configuration different from the local cell, all the configuration parameter information is broadcast in the MBMS NEIGHBORING CELL PTM RB INFORMATION. If the neighboring cell uses the same identification information for the same configuration, no repeated broadcast is required in the MCCH channel.

In fact, during the MBMS service transmission process, the network side may change the RB configuration parameters of the MBMS service. If the non-public RB configuration parameter group used by the current MBMS service is changed, and the changed RB non-common configuration parameter combination information has been set with the corresponding occurrence id, the occurrence id corresponding to the non-public configuration information that changes on the network side is passed. The MCCH channel informs the UE that after receiving the notification information of the MCCH channel, the UE obtains the modified non-public configuration parameter used by the MBMS service according to the non-public configuration parameter combination information corresponding to the identifier in the BCH.

If the R3⁄4 non-public configuration parameters have changed, and these new parameters are not set to The corresponding occurrence id, the network side first sets the corresponding occurrence id for the RB non-common configuration parameter combination, and modifies the corresponding configuration information on the broadcast channel, and the RJB non-public configuration parameter combination information and the corresponding occurrence id are in the BCH to the UE. Transmitting; and notifying the UE through the MCCH channel by the occurrence id corresponding to the changed non-public configuration information;

Of course, if the current RB non-public configuration parameters of the MBMS service change, the network side can directly send the changed non-public configuration parameters to the UE in the MBMS COMMON PTM RB INFORMATION and the MBMS CURRENT CELL PTM RB INFOUMATION of the MCCH channel. In this way, the UE does not need to re-receive the corresponding information on the BCH, and can directly receive the changed non-public configuration parameters from the MCCH channel. This approach is suitable for situations where the RB non-common configuration parameters change less.

In this case, if the changed RB non-common configuration parameter combination does not set a corresponding occurrence id, the network side may further set a corresponding occurrence id for the RB non-common configuration parameter combination, and modify corresponding configuration information on the broadcast channel. The RB non-common configuration parameter combination setting and the corresponding occurrence id are sent to the UE in the BCH.

When the configuration parameter of the current MBMS service is changed, and the changed RB non-public configuration parameter has the corresponding occurrence id, the RRC will notify the UE of the occurrence id corresponding to the non-public configuration information that has changed through the Paging or DCCH dedicated channel; If the changed RB non-common configuration parameter combination does not set the corresponding occurrence id, the RRC will notify the UE of the occurrence id corresponding to the non-common configuration information that has changed through the Paging or DCCH dedicated channel; and modify the corresponding non-public configuration on the broadcast channel. Parameter information: After receiving the notification information, the UE receives the non-public configuration parameter information corresponding to the occurrence id in the broadcast channel, and obtains the modified configuration parameter used by the MBMS service.

The third method for notifying the MBMS service radio bearer configuration parameter of the present invention includes: A. The network side periodically broadcasts the RB common configuration parameter of the MBMS service on the BCH;

C. The public configuration parameter obtained by the UE having the MBMS service function from the BCH, and the non-public configuration parameter used for receiving the current MBMS service from the MCCH or receiving the current MBMS service through the Paging. or DCCH dedicated channel. The non-common configuration parameters used are combined to obtain the RB configuration parameters used by the current MBMS service.

A third preferred embodiment of the present invention employs the third method of the present invention. In the embodiment, the configuration parameters are the RB common configuration parameters, and the determination methods of the RB non-common configuration parameters are the same as the second preferred embodiment, and are not repeated here.

Referring to FIG. 4, FIG. 4 is a flow chart of transmitting RB configuration parameters in a third preferred embodiment of the present invention. The process includes the following steps:

Step 403: Establish a PTP RB with the UE, and end the process. Step 404: The RC determines the RB configuration parameter information of the current MBMS service, and obtains the RJB non-public configuration parameter information therein.

Step 405: Send the RB non-public configuration parameter information on the MCCH channel.

Step 406: The UE receives the RB non-common configuration parameter information, and combines it with the RB common configuration parameter information received from the BCH channel as the RB configuration parameter information of the current MBMS service.

Applying the above steps, the UE can obtain the complete RB configuration parameter of the MBMS service by receiving the broadcast channel and the MCCH, and then receiving the MBMS service at the specified activation time according to the R configuration parameter.

The fourth method for informing the MBMS service radio bearer configuration parameter is that the RB common configuration parameter for the MBMS service is used as a default configuration in the protocol, and the method further includes the following steps:

B. The UE with the MBMS service function receives the non-public configuration parameters used by the current MBMS service from the MCCH, or receives the non-public configuration parameters used by the current MBMS service through the Paging or DCCH dedicated channel, and solidifies it in the protocol.

These cured RB configuration parameters can also be changed through the entire reconfiguration process of the network.

The method for determining which configuration parameters are the RB common configuration parameters and which parameters are the RB non-public configuration parameters in this embodiment is the same as the second preferred embodiment, and is not repeated here. Referring to FIG. 5, FIG. 5 is a flowchart of transmitting RB configuration parameters in a fourth preferred embodiment of the present invention. The process includes the following steps:

Step 500: The UTRAN receives the MBMS session start indication sent by the core network, and performs step 501.

Step 501: Perform a user counting process, and determine a radio bearer mode of the MBMS service. If the current MBMS service adopts the PTP bearer mode, step 502 is performed; if the MBMS service adopts the PTM bearer mode, step 503 is performed.

Step 502: Establish a PTP RB with the UE, and end the process.

Step 503: The R C determines the RB configuration parameter information of the current MBMS service, and obtains the RB non-public configuration parameter information in the RB.

Step 504: Send the RB non-public configuration parameter information on the MCCH channel.

Step 505: The UE receives the RB non-public configuration parameter information, and combines it with the RB common configuration parameter information that is solidified in the protocol, as the RB configuration parameter information of the current MBMS service.

Applying the above steps, U can obtain the complete RB configuration parameter of the MBMS service by receiving the broadcast channel and the MCCH, and then receiving the MBMS service at the specified activation time according to the RB configuration parameter.
