Table one
An existing MBMS conversation procedure comprises two parts: at first partly notify a MBMS session of RNC to be about to begin by core net; Be that BSC/RNC foundation is used for the Radio Resource of MBMS transmission data to necessity of UE interested then.Wherein, whether BSC/RNC sets up radio bearer, and the radio bearer of setting up point-to-point is still put the radio bearer of multiple spot, is determined by carrying out counting process by BSC/RNC.
When BM-SC is ready to send data, trigger the MBMS session and begin process.The session process that begins activates in the network and is used for the bearing resource of all needs of MBMS transmission data, and notifies interested UE to be about to begin transfer of data.By this process, BM-SC offers interested relevant network node with QoS, MBMS business domains, the estimation length of session parameter session attributes such as (if present) of MBMS.By this process, can cause relevant RNC and carry out conversation informing at Access Network, the community user counting, radio bearer type is selected, work such as wireless and wired load plane foundation.
At network configuration shown in Figure 2, below the conversation procedure of prior art MBMS is introduced.
Referring to Fig. 3, Fig. 3 begins schematic flow sheet for prior art MBMS session.This flow process may further comprise the steps:
Step 301, the GGSN that BM-SC preserves in " downstream node listing " parameter in its corresponding MBMS bearer context sends session and begins request message (Session Start Request), the indication transmission that is about to begin, and the status attribute that the MBMS bearer context is set is " activation ".QoS, MBMS business domains are provided in this request, have estimated the session attributes such as length of this session.
Step 302, after GGSN receives that session begins request message, the session attribute that provides in this message is provided in the middle of the MBMS bearer context, the status attribute that the MBMS bearer context is set is " activation ", and begins response message (Session Start Response) to session of BM-SC transmission.
Step 303, the SGSN that GGSN preserves in " downstream node listing " parameter in its corresponding MBMS bearer context sends a MBMS session and begins request message (MBMS SessionStart Request).
Step 304, after SGSN receives that the MBMS session begins request message, in the middle of the MBMS bearer context, preserve session attribute, and the status attribute that the MBMS bearer context is set is " activation ", send a MBMS session to GGSN and begin response message (MBMS Session StartResponse), the tunnel destination node sign (TEID) that is used for load plane is provided in this message, has been used for GGSN and sends the MBMS data.
Step 305, SGSN sends a MBMS session and begins request message (MBMS Session Start Request) to each BSC/RNC that links to each other with this SGSN, has comprised session attribute in this message.
Step 306, BSC/RNC judges it whether in the MBMS business domains, if BSC/RNC in the MBMS business domains, then earlier in the MBMS bearer context, preserves session attribute, the status attribute that the MBMS bearer context is set is " activation ", execution in step 307 then; Otherwise direct execution in step 307.
Step 307, BSC/RNC sends a MBMS session to SGSN and begins response message (MBMS Session Start Request).
A BSC/RNC has received a plurality of MBMS sessions and has begun request message, carries Iu load plane parameter in the message, only returns a MBMS session and begins response message, is used to set up an Iu planes carry that arrives a SGSN.
If BSC/RNC is in the MBMS business domains, then BSC/RNC begins to comprise TEID in the response message in the MBMS session, is used for the Iu load plane that this SGSN is used to send the MBMS data.
If BSC/RNC is not in the MBMS business domains, then it begins in the response message to the MBMS session that SGSN sends, and BSC/RNC is not in the MBMS business domains in indication.
Then, BSC/RNC just can set up in the MBMS business domains and be used for the Radio Resource of MBMS transmission data to necessity of UE interested.
In the prior art, after BSC/RNC received that MBMS session that SGSN sends begins message, the number of users that expectation in each sub-district in this BSC/RNC is received this MBMS session was added up, thereby whether decision sends the MBMS session data in this sub-district.
Referring to Fig. 4, the flow chart that Fig. 4 adds up the reception user for BSC/RNC.This flow process comprises following three steps:
Step 401, BSC/RNC has activated this MBMS business in the sub-district UE sends apply for information, inquires whether this UE receives this MBMS session.
Step 402 agrees that the UE that receives this MBMS session returns inquiry response messages to BSC/RNC.
Step 403, BSC/RNC agrees that to having returned the UE that receives response adds up, and determines to receive number of users according to statistics.Concrete method is: if the UE that is inquired agrees to receive this MBMS session, then BSC/RNC has returned this and has agreed that the UE that receives response charges to the number of users that expectation receives this MBMS session; Otherwise BSC/RNC will not charge to the number of users that expectation receives this MBMS session to this UE.
BSC/RNC has set in advance a user number counting threshold value, if after all UE that return response have been added up, the total number that expectation receives the user of this MBMS session does not reach the user number counting threshold value, and then this total number is exactly the reception number of users that the radio bearer mode is set up in decision.If the UE that returns response is being carried out in the statistic processes, the total number that expectation receives the user of this MBMS session has reached the number of users threshold value, then BSC/RNC stops to receive the inquiry response messages that other UE return, and the user number counting threshold value is exactly the reception number of users that the radio bearer mode is set up in decision.
BSC/RNC is according to the number of users of this MBMS session of expectation reception, and whether decision sends.If send, also receive the number of users of this MBMS session and the mode that other RRM algorithms determine to set up accordingly the Radio Resource carrying according to expectation.Fewer at the number of users that expectation receives, just number of users does not reach under the situation of counting threshold value, adopts the transmission means of point-to-point; Many at number of users, just number of users reaches under the situation of counting threshold value, adopts the transmission means of point to multiple spot.
At present, the MBMS business can be carried multiple business, comprises that video, audio frequency need the user to confirm the business that receives like this; Comprising such as text, little picture, file download, advertisement etc. does not need the user to confirm the business that receives yet.If these do not need the user to confirm that the service-user that receives proceeds inquiry and BSC/RNC is also to having added the back, the load and the mutual complexity of network signal of wave point have then been increased.Also increased simultaneously the answering of UE, power consumption more.

Step 305, SGSN is to each BSC/RNC that links to each other with this SGSN, send a MBMS session and begin request message (MBMS Session Start Request), comprised session attribute in this message, this message has also been carried simultaneously and has been set to invalid inquiry sign.
Step 306, BSC/RNC judges it whether in the MBMS business domains, if BSC/RNC in the MBMS business domains, then earlier in the MBMS bearer context, preserves session attribute, the status attribute that the MBMS bearer context is set is " activation ", execution in step 307 then; Otherwise direct execution in step 307.
Step 307, BSC/RNC sends a MBMS session to SGSN and begins response message (MBMS Session Start Request).
A BSC/RNC has received a plurality of MBMS sessions and has begun request message, carries Iu load plane parameter in the message, only returns a MBMS session and begins response message, is used to set up an Iu planes carry that arrives a SGSN.
If BSC/RNC is in the MBMS business domains, then BSC/RNC begins to comprise TEID in the response message in the MBMS session, is used for the Iu load plane that this SGSN is used to send the MBMS data.
If BSC/RNC is not in the MBMS business domains, then it begins in the response message to the MBMS session that SGSN sends, and BSC/RNC is not in the MBMS business domains in indication.
Then, BSC/RNC just can set up in the MBMS business domains and be used for the Radio Resource of MBMS transmission data to necessity of UE interested.
After BSC/RNC received that MBMS session that SGSN sends begins message, the number of users that expectation in each sub-district in this BSC/RNC is received this MBMS session was added up, thereby whether decision sends the MBMS session data in this sub-district.
Referring to Fig. 5, Fig. 5 sets up the flow chart of Radio Resource for BSC/RNC in a preferred embodiment of the present invention.In the present embodiment, BSC/RNC has set in advance a user number counting threshold value by the method that prior art is provided with the user number counting threshold value.This flow process may further comprise the steps:
Step 501, the MBMS session that BSC/RNC receives the SGSN transmission begins message.
Whether the inquiry sign that step 502, the MBMS session that the BSC/RNC judgement receives begin in the message is effective, if effectively, then execution in step 503; Otherwise execution in step 504.
In the present embodiment, it is invalid that BM-SC inquires that according to Business Nature sign is set to, so the direct execution in step 504 of present embodiment.
Step 503 is carried out the prior art flow process, and the UE that returns inquiry response messages is added up, and determines to receive number of users by the number of the UE that adds up.Execution in step 505 then.
Existing procedure described here, BSC/RNC shown in Figure 4 exactly is to receiving the flow process that the user adds up.
Step 504 all is ready to receive the number that this session determines to receive the user according to the user of all activated this MBMS business.Specifically may further comprise the steps:
A, BSC/RNC have activated this MBMS business in the sub-district UE sends the counting request;
B, the UE that all receive that counting is asked respond to the BSC/RNC feedback count;
C, BSC/RNC add up the UE of feedback count response; Determine to receive user's number by the UE number of statistics.
After if the UE that BSC/RNC responds all feedback count has added up, the UE number of statistics does not reach predetermined user counting threshold value, and then Tong Ji UE number is defined as receiving user's number;
If the UE of feedback count response is carried out in the statistic processes at BSC/RNC, the UE number of statistics has reached predetermined user counting threshold value, then BSC/RNC stops to receive the counting response of UE feedback, and predetermined user is counted the number that threshold value is defined as receiving the user.
Step 505, BSC/RNC sets up the Radio Resource carrying according to the number of users decision transmission means that expectation receives this MBMS session.
Same as the prior art, if decision sends, also receive the number of users of this MBMS session and the mode that other RRM algorithms determine to set up accordingly the Radio Resource carrying according to expectation.Fewer at the number of users that expectation receives, just do not reach under the situation of user number counting threshold value, adopt the transmission means of point-to-point; Many at number of users, just reached under the situation of user number counting threshold value, adopt the transmission means of point to multiple spot.
MBMS business of the present invention is meant multicast service.Because multicast service only sends corresponding information to the user who has subscribed to some information, the broadcasting service then user of all in wireless network sends information, therefore, multicast service need be added up receiving the user, and broadcasting service does not need to add up receiving the user.
By the above embodiments as seen, for not needing the user to confirm the business that receives such as text, little picture, file download, advertisement etc., adopt and determine among this MBMS of the present invention to receive after the method for number of users, reduce the waste of radio network interface resource, simplified the network signal flow process.Avoid unnecessary UE answering, made UE power saving more, increased the stand-by time of UE.
