Description
Technical field
The present invention relates to multimedia broadcasting and multicast service (being called for short MBMS), particularly a kind of method of notifying MBMS relevant information.
Background technology
MBMS is formulating relevant criterion for it to carry out a standardized new business in the 3-G (Generation Three mobile communication system) partner program.The MBMS business is a kind of unidirectional point to the business of multipoint system (promptly broadcasting out multi-medium data from single data source is sent to a plurality of users through Network Transmission and receives).The maximum characteristics of this business are that it can effectively utilize Radio Resource and Internet resources.The MBMS business is mainly used in the wireless communication network system, as Wideband Code Division Multiple Access (WCDMA) communication system, and global system for mobile communications etc.The transmission of business datum will be passed through basically among the MBMS: transmission in data source transmission, go-between transmission, the purpose cell null, user receive such plurality of processes.Fig. 3 is a wireless communication system logical network equipment drawing that the MBMS business can be provided, and in fact MBMS has utilized general grouped wireless data service (hereinafter to be referred as GPRS) network as core transport network in the figure.As shown in Figure 3, broadcasting and multicast service center (hereinafter to be referred as BM-SC) are the data sources that sends the MBMS business datum; Gateway GPRS Support Node (hereinafter to be referred as GGSN) is used for being connected of GRPS network and external network (as the INTERNET network); Gateway GPRS Support Node connects BM-SC and the MBMS data is sent to specific Serving GPRS Support Node (hereinafter to be referred as SGSN) in the MBMS business; CBC is the data source of Cell Broadcast CB, by with CBC and BM-SC interconnection, makes CBC that MBMS can be provided professional declaration function in MBMS; SGSN is used for that UE is carried out access control and mobile management and simultaneously the MBMS data of coming from GGSN is sent to specific radio-cell controller (hereinafter to be referred as RNC); RNC is used for controlling one group of base station and multi-medium data is sent to specific base stations; Aerial physical channel is set up for the MBMS business of certain sub-district in the base station under the control of RNC; Subscriber terminal equipment (hereinafter to be referred as UE) is the terminal equipment that receives the MBMS data.
Provided the MBMS business among Fig. 4 and be established to all processes that end user is left from business declaration, user's adding, service announcements, radio bearer.
401 subscribe to the contact of setting up between user and the service provider, and authorized user can receive relevant MBMS service.
The MBMS business that 402 professional declarations notify the user to provide.For example, system in the afternoon 7:00 relay a football match in areas of Beijing.
403 add the expression users adds a group, promptly the user tell network he or she be ready to receive this multicast service.
404 MBMS sessions begin to represent that being established as the MBMS transfer of data sets up Internet resources.
405 MBMS notice is informed the MBMS transfer of data that the user will carry out at once.
406 data transfer representation MBMS business data transmission are to user's process.
407 MBMS conversation ends are represented after the MBMS business data transmission is finished, releasing network resources.408 leave and add correspondingly with 403, and the expression user will leave a group, does not promptly rethink to receive certain professional data.
The MBMS business the mode that normally adopts point-to-multipoint is provided, in cable network and wave point transmission, all only transmit a piece of data, can save Internet resources and air interface resource like this, the resource of especially aerial spreading code.But when the number of users that receives certain MBMS business in sub-district is less,, not that the point-to-multipoint Channel Transmission can be saved resource, and be to use many point-to-point transmission channels can the better utilization Internet resources from the transmitting power of base station.Number of users critical value that the MBMS system has been each little area definition, i.e. the boundary of point-to-multipoint Channel Transmission and point-to-point channel transmission conversion.When number of users during greater than this critical value, network is set (when service conversation begins) or conversion (service conversation carry out in) with the relevant information of this sub-district and is the point-to-multipoint pattern, promptly uses Common transport channel.Otherwise when number of users during less than this critical value, network is set (when service conversation begins) or conversion (service conversation carry out in) with the relevant information of this sub-district and is ad hoc mode, promptly uses dedicated transmission channel.
In the WCDMA system, the mode of setting up of Common transport channel and dedicated transmission channel and process are different fully, and the residing RRC state of subscriber equipment when using different transmission channel also is different.
In the WCDMA system, the residing state of user, the angle that connects from Radio Resource control (RRC) has five: idle condition (idle), cell paging channel status (cell_pch), cell downlink access channel state (cell_fach), cell dedicated channel status (cell_dch) and URA paging channel state (ura_pch).In these five states, for the MBMS business, the data of can accepting business.But special requirement for restriction is arranged under some situation.Other states except idle condition, we can say that subscriber equipment is in connection status.
When subscriber equipment was in idle condition, it may be received in the MBMS data of point-to-multipoint channel, but because its with radio network controller (RNC) between do not have RRC to be connected, this subscriber equipment can not receive other business datums.When free subscriber carries out the sub-district when reselecting, generally do not carry out any communication between subscriber equipment and the network, subscriber equipment self is by measuring the sub-district that changes current place.These processes have a detailed description at the protocol specification of WCDMA, do not do at this and give unnecessary details.
When subscriber equipment is in the cell paging channel status, it is also only to be received in the MBMS data of point-to-multipoint channel, but it with radio network controller between have RRC to be connected, thereby network can find this subscriber equipment by send message on paging channel.This subscriber equipment also can be initiated up signaling at any time and be connected, and carries out mutual between the network.When this subscriber equipment moved new sub-district, it will be done the sub-district and reselect, in case subscriber equipment moves to a new sub-district and selected this letter sub-district as its purpose sub-district, it will send message to network so, its present position of informing network.This process is normally finished by cell update.
When subscriber equipment was in descending access channel state, it not only may be received in the MBMS data of point-to-multipoint channel, and can go up the proprietary data that receives this subscriber equipment at descending access channel (FACH).Although the transmission of MBMS data may may not transmitted on same physical channel with the proprietary data of subscriber equipment, as long as subscriber equipment is had the ability, it just can receive MBMS data and proprietary data simultaneously.Have RRC to be connected between the subscriber equipment of this state and radio network controller, network allocation is given its Dedicated Control Channel (DCCH), make it with network between can keep at any time communicating by letter.This subscriber equipment can be initiated up signaling at any time and be connected, and carries out mutual between the network.When this subscriber equipment moved new sub-district, it will be done the sub-district and reselect, in case subscriber equipment moves to a new sub-district and selected this letter sub-district as its purpose sub-district, it will send message to network so, its present position of informing network.This process is normally finished by cell update.
When subscriber equipment was in cell dedicated channel status, it not only can receive the MBMS data, and can receive and send the proprietary data of this subscriber equipment on the dedicated channel (DCH) of network to its configuration.The transmission of MBMS data may may not transmitted on same physical channel with the proprietary data of subscriber equipment, but as long as subscriber equipment is had the ability, it just can receive MBMS data and proprietary data simultaneously.It may be because the cause of proprietary business also may be because the MBMS business of user sub-district of living in is the cause that provides by dedicated channel that subscriber equipment is in this state.Have RRC to be connected between the subscriber equipment of this state and radio network controller, network allocation is given its Dedicated Control Channel (DCCH), make it with network between can keep at any time communicating by letter.This subscriber equipment can be initiated up-downgoing signaling and transfer of data at any time, and carries out mutual between the network.When this subscriber equipment moved new sub-district, it will do cell measurement, measurement report was given its service wireless network controller.If network is found the enough good in purpose cell signal quality of this user report, network just may allow subscriber equipment set up new Radio Link in new sub-district, and (if the user has only this professional relevant information of MBMS business and Target cell is point-to-point, perhaps this user has other dedicated service), this subscriber equipment will be set up the point-to-multipoint channel between itself and network else if, and correspondingly, the state of subscriber equipment can be transferred to descending access channel state or cell paging channel status, generally do not advise this subscriber equipment is transferred to URA paging channel state, because user's mobility is to be unit with URA (generally comprising a plurality of sub-districts) under this state, be not easy to add up number of users.
When subscriber equipment was in URA paging channel state, it was also only accepting the MBMS data, but it with radio network controller between have RRC to be connected, thereby network can find this subscriber equipment by send message on paging channel.This subscriber equipment also can be initiated up signaling at any time and be connected, and mutual between the network.When this subscriber equipment moves to new sub-district, from system information, know the URA sign of new sub-district, if the URA of new sub-district sign and old sub-district is the same, this subscriber equipment does not carry out with network alternately.And in case the URA of new and old sub-district sign is inconsistent, it will be URA and reselect, and this process is normally more newly arrived by URA and finished.
When the subscriber equipment that is in connection status is mobile between different RNCs, between these two RNC the Iur interface is arranged.The original RNC of subscriber equipment is called its Serving RNC (SRNC), and the new RNC that moves to is called its Drift Radio Network Controller (DRNC).
Because the present invention is relevant with the process of cell update, be reference at this with Fig. 9, the process of cell update is once described.
When subscriber equipment moves to the edge of a plurality of sub-districts, currently just can die down at the cell signal of received signal, subscriber equipment can scan the signal strength signal intensity of other sub-districts.Satisfy the condition that the sub-district is reselected if find the signal strength signal intensity of new sub-district, it is synchronous that subscriber equipment will carry out the sub-district in new sub-district so, obtains new sub-district P-CCPCH channel, read system information.From system information, subscriber equipment obtains the configuration information of the up RACH of access channel immediately, behind the transmission channel and physical channel of the intact up channel of user device configuration, just can send information to network.
The subscriber equipment that is in cell paging channel status and cell downlink access channel state will send RRC message " cell update " to network at this moment, and after the DRNC of subscriber equipment received this message, it can check whether this message identifies with U-RNTI.If DRNC is encapsulated into this message in the Iur message " up signaling transmission indication ", what comprise as the L3 information among Fig. 9 is exactly cell update message by the subscriber equipment transmission.After SRNC received " up signaling transmission indication ", it can be decoded to it, learns that UE has entered new sub-district.SRNC can send the cell update acknowledge message to UE according to the state of subscriber equipment.If SRNC decision UE is the cell paging channel status, SRNC sends " downlink signaling transmission indication " message to DRNC so, carries the cell update acknowledge message in this message.If SRNC decision UE state is the cell downlink access channel state, SRNC sends packet to DRNC so, wherein carries the cell update acknowledge message, and this packet sends to subscriber equipment by DRNC.
The present invention is only relevant with the cell downlink access channel state with the cell paging channel status, because idle condition, the sub-district of the subscriber equipment of URA paging channel state and cell dedicated channel status is reselected complete different with these two kinds, therefore not within limit of consideration of the present invention.The subscriber equipment of this two states is all wanted the first information of obtaining current area from system information because carry out the sub-district when reselecting at it, sends up signaling then.And carry out on multicast control channel (MCCH) about the broadcasting of MBMS type of service, therefore when network sends signaling the relevant information channel type for example of not knowing to support this MBMS business at these three kinds of subscriber equipmenies.And if the relevant information that network does not know to support MBMS business channel type for example, the SRNC of subscriber equipment does not just know what message this sends to DRNC, thereby can not guarantee how subscriber equipment obtains the MBMS business datum quickly and accurately.
Summary of the invention
The method that the purpose of this invention is to provide a kind of notifying MBMS relevant information, newly select for example channel type of relevant information that this user of SRNC of the DRNC notifying user equipment of sub-district receiving the MBMS business by subscriber equipment, whether belong to multicast area and radio bearer information, thereby make SRNC send correct signaling to DRNC, for this MBMS business is set up transmission channel fast, thereby reduce loss of user data.
For achieving the above object, a kind of method of notifying MBMS relevant information comprises step:
When subscriber equipment moves to new sub-district, send cell update message to DRNC;
DRNC checks the message received from UE and the MBMS business about this subscriber equipment of its preservation;
DRNC informs SRNC with these MBMS business in the relevant information of new sub-district;
When SRNC found that the relevant information of the business that current user equipment is receiving is included in this message, it was according to the order of relevant information decision to the DRNC transmission.
The present invention is by allowing DRNC tell the relevant information of the MBMS business that the SRNC subscriber equipment is receiving, thereby can reduce the amount of data lost when the gravity treatment of sub-district, assists state that SRNC determines that fast UE need enter etc.

Embodiment
Below, correct example that present invention will be described in detail with reference to the accompanying.Below only the part of understanding necessity of the present invention is described, can omit to some extent other part in order to give top priority to what is the most important.
The present invention has two different prerequisites, and inventive method is different along with the difference of prerequisite.First prerequisite is that the SRNC of subscriber equipment can preserve among its DRNC the relevant information of ongoing MBMS business in some sub-district, and for example whether channel type belongs to multicast area and radio bearer information.
The SRNC that second prerequisite is subscriber equipment does not preserve among its DRNC the relevant information of ongoing MBMS business in some sub-district, and for example whether channel type belongs to multicast area and radio bearer information.
The present invention is only moving to a new RNC when subscriber equipment, and this RNC could adopt after having preserved the MBMS service identification of subscriber equipment.
Fig. 1 has provided the signaling process that the present invention is based on second prerequisite.
When the subscriber equipment that is in cell_fach and cell_pch moves to new sub-district, if the signal quality of the Common Pilot Channel of the new sub-district that subscriber equipment is measured satisfies certain cell selecting rule, subscriber equipment will send cell update message 101 to its SRNC so.This message upward sends in up Common Control Channel (CCCH).After subscriber equipment moved to new sub-district, it will read new system information of subdistricts, thereby learnt the configuration parameter of S-CCPCH and PRACH in the new sub-district.After subscriber equipment is selected the S-CCPCH that oneself listens to according to the method for stipulating in the present RRC protocol specification and is used for sending the PRACH of uplink information, subscriber equipment is mapped to the RACH channel that comprises among the PRACH with CCCH and gets on, and the DRNC under new sub-district sends cell update message.
Fig. 1 is described 102, when DRNC receives after the message of CCCH transmission, check the content of this message.After DRNC knows that this message is cell update, can determine which the SRNC of this subscriber equipment is by the sign U-RNTI that checks subscriber equipment.The U-RNTI of subscriber equipment is distributed by its SRNC, and this sign comprises two parts: temporary mark S-RNTI and its SRNC sign of being distributed to subscriber equipment by SRNC.DRNC just can know by SRNC sign this signaling is transmitted to that RNC.On the Iur interface, be used for being " up signaling transmission indication " to the message that another RNC transmits the subscriber equipment signaling of receiving from CCCH that this message is that the SCCP with connectionless-mode transmits from a RNC.When transmitting, DRNC will be encapsulated into from the RRC signaling that subscriber equipment is received in " L3 information " information unit of this message.DRNC checks whether set up customer equipment context (this is at the cell_fach subscriber equipment) for this subscriber equipment, and this customer equipment context is to generate when subscriber equipment enters the sub-district of being controlled by this RNC for the first time.If no, DRNC reexamines the U-RNTI (this is at the cell_pch subscriber equipment) that whether comprises this subscriber equipment in the MBMS business contexts.If also do not have, DRNC operates according to prior art so, and this situation is not within solution scope of the present invention.For the cell_fach subscriber equipment, if DRNC has set up customer equipment context for it, DRNC has known all MBMS business that UE subscribes to certainly or has known those ongoing MBMS business so, this depends on the method that business contexts is set up, because it doesn't matter with the present invention, do not give unnecessary details at this.DRNC upgrades the MBMS business contexts of new sub-district, UE place, customer equipment identification is joined in the context of related service of related cell to go, and customer equipment identification is deleted from the business contexts of the related service of old sub-district.DRNC will carry out for example channel type of professional service identification and corresponding relevant information, whether belong to multicast area and radio bearer parameter and be included in the up signaling transmission indicating information.This may relate to a plurality of ongoing business, just comprises the relevant information of a plurality of business like this in this message.Certainly also to comprise other information units in this message, the C-RNTI of subscriber equipment for example, the initial indications of public transmission channel resource etc. are the information of specification description now.Radio bearer information is just to transmit when the channel type of Target cell is the point-to-multipoint mode.If owing to this mobility of user equipment causes the MBMS traffic channel types by the point-to-point point-to-multipoint that becomes, this message can also be indicated SRNC channel type conversion so, and the sign at other subscriber equipmenies of this SRNC that has influence on.After SRNC finds the channel type conversion, other subscriber equipment dedicated channel are configured to common signal channel.The configuration of common channel parameter can be transmitted by SRNC, also can read MCCH by subscriber equipment and obtain.If the DRNC pointer is to some MBMS business, this sub-district does not belong to multicast area, and SRNC can move to idle condition with subscriber equipment so, and with this information notifying user equipment.
Fig. 1 is described 103, after SRNC receives the up signaling transmission of the message that transmits from DRNC indication, determines according to the existing protocol standard how this handles.Because it doesn't matter for this and the present invention, do not give unnecessary details at this.When SRNC found that the relevant information of the business that current user equipment is receiving is included in this message, it will be to the signaling of DRNC transmission according to the relevant information decision.For example, if it is point-to-point mode that Target cell provides professional relevant information, SRNC will send Radio Link to DRNC and set up request message so, thereby for subscriber equipment is set up Radio Link in new sub-district, provide dedicated channel, then configure dedicated channel in sending to " cell update affirmation " message of subscriber equipment.The process of describing in this method and the existing standard of setting up Radio Link is the same, does not give unnecessary details at this.If it is the point-to-multipoint mode that Target cell provides professional relevant information, it is Common transport channel, SRNC is according to actual needs for subscriber equipment is established as the Common transport channel that dedicated service provides transmission channel so, and it is inferior perhaps to determine to allow subscriber equipment still be in the CELL_PCH state.SRNC can also carry the beared information of common signal channel in the message cell update of issuing subscriber equipment is confirmed.SRNC can also not belong to multicast area in sub-district, the present place of notifying user equipment.
Fig. 1 is described 104, if the RRC message that sends subscriber equipment by SRNC sends on CCCH, this RRC message is delivered to DRNC by " downlink signaling transmission " message so, and DRNC sends to subscriber equipment with it on CCCH.Otherwise if this message sends on DCCH, DRNC does not need to do any extra process.
Fig. 2 provides is based on signaling process under first prerequisite.
Fig. 2 is described 201, and when being in cell_fach, when the subscriber equipment of cell_pch carried out cell update, UE can send the RRC message of cell update in the new sub-district of selecting.This message upward sends in up Common Control Channel (CCCH).
Fig. 2 is described 202, when DRNC receives after the message of CCCH transmission, check the content of this message.After DRNC knows that this message is cell update, can determine which the SRNC of this subscriber equipment is by the sign U-RNTI that checks subscriber equipment.The U-RNTI of subscriber equipment is distributed by its SRNC, and this sign comprises two parts: temporary mark S-RNTI and its SRNC sign of being distributed to subscriber equipment by SRNC.DRNC just can know by SRNC sign this signaling is transmitted to that RNC.On the Iur interface, be used for being " up signaling transmission indication " to the message that another RNC transmits the subscriber equipment signaling of receiving from CCCH that this message is that the SCCP with connectionless-mode transmits from a RNC.When transmitting, DRNC will be encapsulated into from the RRC signaling that subscriber equipment is received in " L3 information " information unit of this message.DRNC checks whether set up customer equipment context (this is at the cell_fach subscriber equipment) for this subscriber equipment, and this customer equipment context is to generate when subscriber equipment enters the sub-district of being controlled by this RNC for the first time.If no, DRNC reexamines the U-RNTI (this is at cell_fach and cell_pch subscriber equipment) that whether comprises this subscriber equipment in the MBMS business contexts.If also do not have, DRNC operates according to prior art so, and this situation is not within solution scope of the present invention.For the cell_fach subscriber equipment, if DRNC has set up customer equipment context for it, DRNC has known all MBMS business that UE subscribes to certainly or has known those ongoing MBMS business so, this depends on the method for setting up with business contexts, because it doesn't matter with the present invention, do not give unnecessary details at this.DRNC upgrades the MBMS business contexts of new sub-district, UE place, customer equipment identification is joined in the context of related service of related cell to go, and customer equipment identification is deleted from the business contexts of the related service of old sub-district.DRNC judge whether once with in this sub-district about the relevant information of some ongoing MBMS business channel type for example, whether belong to multicast area and radio bearer parameter sends SRNC to.If no, DRNC will with in this sub-district about the relevant information of some ongoing MBMS business for example channel type and radio bearer parameter be included in the up signaling transmission indicating information, otherwise just do not need to transmit.This may relate to a plurality of ongoing business, just comprises the relevant information of a plurality of business like this in this message.Certainly also to comprise other information units in this message, the C-RNTI of subscriber equipment for example, the initial indications of public transmission channel resource etc. are the information of specification description now.Radio bearer information is just to transmit when the channel type of Target cell is the point-to-multipoint mode.If owing to this mobility of user equipment causes the MBMS traffic channel types by the point-to-point point-to-multipoint that becomes, this message can also be indicated SRNC channel type conversion so, and the identification list at other subscriber equipmenies of this SRNC that has influence on.After SRNC finds the channel type conversion, other subscriber equipment dedicated channel are configured to common signal channel.The configuration of common channel parameter can be transmitted by SRNC, also can read MCCH by subscriber equipment and obtain.If the DRNC pointer is to some MBMS business, this sub-district does not belong to multicast area, and SRNC can move to idle condition with subscriber equipment so, and with this information notifying user equipment.
Fig. 2 described 203, after SRNC receives the up signaling transmission of the message that transmits from DRNC indication, if wherein comprise the relevant information of some MBMS business in some sub-district, SRNC will preserve these information, then will be to the signaling of DRNC transmission according to the relevant information decision of preserving.For example, be point-to-point mode if Target cell provides professional relevant information, SRNC will send Radio Link to DRNC and set up request message so, thereby sets up Radio Link for subscriber equipment in new sub-district, and dedicated channel is provided.The process of describing in this method and the existing standard of setting up Radio Link is the same, does not give unnecessary details at this.If it is the point-to-multipoint mode that Target cell provides professional relevant information, it is Common transport channel, SRNC is according to actual needs for subscriber equipment is established as the Common transport channel that dedicated service provides transmission channel so, and it is inferior perhaps to determine to allow subscriber equipment still be in the CELL_PCH state.SRNC can also carry the beared information of common signal channel in the message cell update of issuing subscriber equipment is confirmed.SRNC can also not belong to multicast area in sub-district, the present place of notifying user equipment.
Fig. 2 is described 204, if the RRC message that sends subscriber equipment by SRNC sends on CCCH, this RRC message is delivered to DRNC by " downlink signaling transmission " message so, and DRNC sends to subscriber equipment with it on CCCH.Otherwise if this message sends on DCCH, DRNC does not need to do any extra process.
The node processing flow process of DRNC
Fig. 5 has described the node processing flow process based on the DRNC of second prerequisite.
In 501 stages, DRNC receives from the message of subscriber equipment and SRNC transmission.
In 502 stages, DRNC judges whether the message of receiving comes identifying user equipment or DRNC to judge whether this message is cell update with U-RNTI.If then turn to 503, otherwise turn to 501.DRNC checks the sign that whether comprises this subscriber equipment in context that whether this subscriber equipment is arranged or the MBMS context.If then turn to 504, otherwise turn to 501.In 504 stages, DRNC checks whether the sub-district at this subscriber equipment place is different with last sub-district, if equally then turn to 501.If different, reexamine new sub-district and whether belong to multicast area at some business, if belong to multicast area, then turn to 505, otherwise turn to 508.In 505 stages, DRNC upgrades the MBMS context of new and old sub-district, is about in the old sub-district deletion of the customer equipment identification in the MBMS business contexts, it is joined in the MBMS business contexts of new sub-district go, and turns to 506.506 stages, judge because whether the adding of this subscriber equipment causes channel type by the point-to-point point-to-multipoint that is converted to, if then turn to 507, otherwise turn to 508.507 stages, DRNC sends up signaling transmission indicating information to the SRNC of subscriber equipment, wherein comprise ongoing MBMS business in the relevant information of new sub-district for example channel type and radio bearer channel parameter, and the DRNC sign at other subscriber equipmenies of SRNC that in this message, also comprises the channel switch indication and have influence on.In 508 stages, DRNC sends up signaling transmission indicating information to the SRNC of subscriber equipment, wherein comprises ongoing MBMS business at the relevant information of new sub-district channel type for example, perhaps whether belongs to multicast area.If channel type is a point-to-multipoint, this message also comprises radio bearer parameter so.
Fig. 6 has described the node processing flow process based on the DRNC of first prerequisite.
In 601 stages, DRNC receives from the message of UE and SRNC transmission.
In 602 stages, DRNC judges whether the message of receiving comes identifying user equipment or DRNC to judge whether this message is cell update with U-RNTI.If then turn to 603, otherwise turn to 601.DRNC checks the sign that whether comprises this subscriber equipment in context that whether this subscriber equipment is arranged or the MBMS context.If then turn to 604, otherwise turn to 601.In 604 stages, DRNC checks whether the sub-district at this subscriber equipment place is different with last sub-district, if equally then turn to 501.If different, reexamine new sub-district and whether belong to multicast area at some business, if belong to multicast area,, otherwise turn to 606 if then turn to 605.In 605 stages, DRNC upgrades the MBMS context of new and old sub-district, is about in the old sub-district deletion of the customer equipment identification in the MBMS business contexts, it is joined in the MBMS business contexts of new sub-district go, and turns to 606.In 606 stages, DRNC judges whether to send about this sub-district at the relevant information such as the channel type of certain MBMS business or whether belong to multicast area, if whether the point-to-multipoint channel sent radio bearer information to SRNC.If then in the up signaling transmission indication that SRNC sends, needn't comprise relevant information at DRNC.Otherwise comprise these contents.If because the adding of this subscriber equipment causes channel type by the point-to-point point-to-multipoint that is converted to, the DRNC sign at other subscriber equipmenies of SRNC that can in this message, comprise the channel switch indication and have influence on so.
The node processing flow process of SRNC
