Description

A kind of method of user joining multimedia broadcast/multicast service

Technical field

The present invention relates to the professional realization technology of multi-medium broadcast/group broadcast (MBMS), particularly a kind of user adds the method for MBMS business.

Background technology

Multicast and broadcasting are a kind of technology that transmits data from a data source to a plurality of targets.In traditional mobile network, cell broadcaste service (CBS:Cell Broadcast Service) allows low bit rate data to share broadcast channel to all users' transmissions by the sub-district, belongs to information series business.

Now, people no longer are satisfied with phone and messaging service to the demand of mobile communication, fast development along with Internet, a large amount of multimedia services emerge, the some of them applied business requires a plurality of users can receive identical data simultaneously, as video request program, television broadcasting, video conference, online education, interactive game etc.These mobile multi-media services are compared with general data, have characteristics such as data volume is big, longer duration, delay sensitive.Present IP multicasting technology only is applicable to wired IP network, is not suitable for the mobile network, because the mobile network has particular network structure, functional entity and wave point, these are all different with wired IP network.

In order to effectively utilize mobile network resource, the WCDMA/GSM global standardsization organize 3GPP to propose multimedia broadcast/multicast service (MBMS:Multimedia Broadcast/Multicast Service), in the mobile network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, improve utilization rate of network resource, the utilance of the interface resource of especially eating dishes without rice or wine.The MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of following mobile data development undoubtedly.

In order to support the MBMS business, increased mobile network functional entity---broadcast multicast service center BM-SC among the mobile network newly, it is content provider's a inlet, be used for authorizing and initiating the MBMS bearer service at mobile network, and plan transmits the MBMS content to schedule.In addition, functional entitys such as subscriber equipment (UE), land radio access web (UTRAN), GERAN, SGSN, GGSN strengthen, and have increased the relevant function of MBMS.

Such network configuration is referring to Fig. 1, and Fig. 1 is for supporting the wireless network architecture schematic diagram of multicast/broadcast business.Wherein, broadcast/multicast service center (BM-SC) is passed through Gmb interface or Gi interface and gateway general packet radio service (GPRS) support node (GGSN, Gateway GPRS SupportNode) and is linked to each other, and a BM-SC can link to each other with a plurality of GGSN; GGSN links to each other by Gn/Gp interface and Serving GPRS Support Node (SGSN, Serving GPRS Support Node), and a GGSN can link to each other with a plurality of SGSN; SGSN can link to each other with universal mobile telecommunications system (UMTS) land radio access web (UTRAN) by the Iu interface, UTRAN links to each other with communication terminal by the Uu interface then, SGSN also can strengthen wireless access network (GERAN) by Iu/Gb interface and global system for mobile communications (GSM) and link to each other, and GERAN links to each other with communication terminal by Um Interface then.

MBMS comprises multicast pattern and broadcast mode.The distinctive points of multicast service and broadcasting service only is: multicast service only sends corresponding information to the user who has subscribed to some information, and the broadcasting service then user of all in wireless network sends information.Multicast pattern needs user's corresponding multicast group of contracting, and carries out activation of service, and produces corresponding charge information.Because it is different that multicast and broadcast mode exist, cause also difference of its operation flow on business demand.

Send information because the broadcasting service of MBMS is all users in wireless network, do not need user's adition process, so followingly only the multicast service process of MBMS is described.

Referring to Fig. 2, Fig. 2 is the entire flow of user's receiving multicast business, comprising: subscription (Subscription), service statement (Service announcement), adding (Joining), session begin (Session Start), MBMS notice (MBMS notification), transfer of data (Datatransfer), conversation end (Session Stop) and leave (Leaving) process.

Wherein, the Subscription process is used for allowing the user subscribe to required MBMS service in advance.

Service announcement process is used for by the current service that can provide of BM-SC declaration.

The Joining process is a MBMS activating multicast service process, UE is in the Joining process, informing network self is ready to become the member of current multicast group, receive corresponding professional multicast packet, this Joining process can be created the MBMS UE context of record UE information in the UE of network and adding multicast group.

In the Session Start process, BM-SC is ready to transfer of data, and informing network is set up the bearing resource of corresponding core net and Access Network.

MBMS notification process is used to notify UE MBMS multicast conversation to be about to begin.

In the Data transfer process, BM-SC transfers data to UE by the bearing resource that session begins to set up in the process.

The bearing resource that Session Stop process is used for Session Start process is set up discharges.

The Leaving process makes the subscriber in the group leave multicast group, i.e. user's receiving multicast data no longer, and this process can be with corresponding MBMS UE context deletion.

In MBMS multicast service flow process, the user add and session to begin two steps be separate, that is to say a user may be before session begins also may the session after session begins carry out in multicast service of adding.

It is to show that he is ready to receive this business that the user adds certain business actual, and after the manual business of selecting to like of user, UE just initiates to add the process of this MBMS business to network side.

The process that the user adds a MBMS business is a Non-Access Stratum (NAS) process.This process is generally speaking fairly simple, and according to the regulation in the agreement [1], at present the NAS adition process comprises totally 4 steps of following two stages:

In first stage, in the service selection stage, comprising: step 1, user select a MBMS business.

In second stage, transmission joins request the stage, comprising:

The NAS indication Access Layer (AS) of step 2, UE adds this MBMS business.

Step 3 after AS receives indication, is set up the RRC connection or is carried out cell updating course according to the state of current UE.Concrete grammar is:

Prepare to add certain MBMS business if A is in the UE of free time (IDLE) state, these UE need carry out the RRC connection and set up process so;

If B be in UTRAN Acceditation Area-paging channel (URA-PCH) and sub-district-paging channel and (CELL-PCH) user of state prepare to add certain MBMS business, these UE need at first carry out cell updating course so.

Step 4, AS send to core net with user's message that joins request, and add this MBMS business.

After the UE adding business, all created among network side and the UE should business MBMS UE context.Like this, UE can accurately receive this MBMS business datum.

Under the UE open state, when the user will stop to receive certain MBMS business, manual earlier selected this business, UE initiates to go adition process to network side then, go adition process similar to adition process, just the informing network side stops to receive this business, and network side and UE delete this professional MBMSUE context respectively.Like this, UE can not receive this MBMS business datum again.

In addition, when the UE normal shutdown, network side and UE can delete all professional MBMS UE contexts of UE respectively.Like this, when UE starts shooting again, can not receive the MBMS business datum that adds before the shutdown again.UE must reselect, add again if also will add certain MBMS business.

From top prior art process as can be seen, the user has added certain MBMS business, and shutdown back UE does not store the business of adding.Therefore, when each UE started shooting again, even relatively hobby and the often business of adding still need the manual selection of user to add this business again, operating procedure was very loaded down with trivial details for the user like this.

In fact, the user for to add professional fancy grade be different.Give an example, certain user is to some business, and is interested especially such as weather forecast, after he adds this business so, just wishes all to obtain this service always; And for entertainment news, then may be that certain is interesting, be not interested all the time.

As seen, the prior art scheme can't reflect the fancy grade of user for different business adding, more can't add the MBMS business in different ways according to the user preferences degree.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of user to add the method for MBMS business, and this method can reflect the fancy grade of user for different business adding.Further purpose of the present invention is to add functions such as MBMS business automatically according to user's fancy grade realization.

For achieving the above object, technical scheme of the present invention specifically is achieved in that

The method of a kind of user joining multimedia broadcast/multicast MBMS business, this method comprises:

In the service selection stage of the professional adition process of a MBMS, after UE received the business of user's selection, the prompting user was an occasional service or long-time professional with this business setting;

If this business setting is long-time professional, the business information that this is professional is stored among the UE;

Carry out the join request step in stage of follow-up transmission in the adition process.

Wherein, the method for the long-time professional business information of described storage can for: the business information of each long-time MBMS business is stored in the service lists.

The described service selection stage in the professional adition process of a MBMS, the professional back prompting user that UE reception user selects is that occasional service or professional for a long time step may further include with this business setting: read service lists, judge whether this professional business information has been stored in the service lists, if then point out the user whether to reset the adding type, if not, if then be that described this business setting is carried out for long-time professional in occasional service or long-time professional back with this business setting, the business information that this is professional is stored in the step among the UE, otherwise carries out the join request step in stage of follow-up transmission in the described adition process.

The MBMS business setting that the user will need once to add is an occasional service; With the permanent MBMS business setting that adds of needs is long-time professional;

The method of the business information of the long-time MBMS business of described storage is: the service identification of each long-time MBMS business is stored in the service lists.

This method may further include:

When restarting after the UE shutdown, UE reads the service identification of each long-time MBMS business from service lists, and the long-time business in the service lists is carried out the join request step in stage of follow-up transmission in the described adition process one by one.

The MBMS business setting that the user will need once to add is an occasional service; The MBMS business setting that need add at finite time is long-time professional;

The method of the business information of each long-time MBMS business of described storage is: the service identification of each long-time MBMS business and the joining day of user's setting are stored in the service lists.

This method may further include:

C, carry out the join request step in stage of follow-up transmission in the adition process.

The present invention has numerous embodiments, can the adding type be set by the joining day, also can the adding type be set by adding indegree.Below be elaborated respectively for three embodiment.

By the joining day adding type is set, can two kinds of situations: be set to occasional service or permanent customer service, also can be set to occasional service or finite time business.

Embodiment one:

In this enforcement, the user is set to occasional service or permanent professional by the time.Present embodiment is provided with a service lists that is used to store the business information of permanent business in UE, referring to Fig. 3, Fig. 3 is the manual schematic flow sheet that adds the MBMS business of the present invention's first preferred embodiment.It may further comprise the steps:

Step 301, UE receives the MBMS business that the user selects.

Step 302 reads service lists, and whether judge has this professional business information such as service identification in the service lists, if having, then execution in step 303; Otherwise execution in step 304.

In the present embodiment, can revise the setting of user, certainly, also can not read service lists here and judge, and directly point out the user that the adding type is set by this step to business adding type.

Step 303, whether the prompting user resets the adding type, if execution in step 305 then, otherwise execution in step 308.

Step 304, the adding type that the prompting user is provided with this business is an occasional service or permanent professional.

Step 305 is provided with the adding type of this business.

Step 306 judges whether this business is permanent business, if then execution in step 307, otherwise execution in step 308.

Step 307, the business information such as service identification that this is professional store in the service lists.

Step 308, the NAS indication AS of UE adds this MBMS business.

Step 309 is carried out RRC according to the UE current state and is connected or cell update.

Step 310, AS sends to network side with the information of joining request, and adds this MBMS business.

Step 308 in the present embodiment～310 are exactly join request three steps in stage of the transmission of prior art.

Like this, behind the UE cycle power, UE just can directly read the service identification of each permanent MBMS business from service lists, then the long-time business in the service lists is carried out three steps that send the stage that joins request one by one, thereby realize adding automatically the MBMS business, detailed process is referring to Fig. 4, and Fig. 4 adds the schematic flow sheet of MBMS business automatically for after the UE start is restarted in embodiment illustrated in fig. 3.This flow process may further comprise the steps:

Step 401 reads service lists.

Step 402 is selected a business.

Step 403 sends the stage step that joins request at this business execution.

Step 404 judges whether to also have unselected business, if then return step 402, otherwise finishes.

As seen, use the present invention's can very simply realize starting shooting automatic adding MBMS business function after restarting.

Embodiment two:

In this enforcement, the user is set to occasional service or finite time business by the time.Present embodiment is provided with a service lists that is used for the business information of memory limited time business in UE.The flow process of the manual adding of present embodiment MBMS business and schematic flow sheet embodiment illustrated in fig. 3 are basic identical, and difference only is that the business information of storing in the service lists in the present embodiment comprises service identification and professional joining day.The joining day of storing in the present embodiment can be the concluding time that the user is provided with, and also can be after the user is provided with the time period, the concluding time that system-computed goes out.

Like this, behind the UE cycle power, UE just can directly read the service identification of each finite time MBMS business from service lists, carry out three steps that send the stage that joins request then, thereby realize adding automatically the MBMS business, detailed process is referring to Fig. 5, after Fig. 5 is restarted for the present invention second preferred embodiment UE starts shooting, automatically add the schematic flow sheet of MBMS business, it may further comprise the steps:

Step 501 reads service lists.

Step 502 is selected a business.

Step 503 is judged the current time whether in the joining day that the user is provided with, if execution in step 508 then, otherwise execution in step 504.

Step 504, whether the prompting user continues, if execution in step 506 then, otherwise execution in step 505.

During practical application, also can not reresent the user, so long as surpass user's joining day, with regard to execution in step 510.

Step 505, after service identification that should business in the deletion service lists, the joining day deletion, execution in step 510.

Step 506, whether the prompting user is the finite time business with this business setting also, if execution in step 508 then, otherwise execution in step 507.

Step 507, after service identification that should business in the deletion service lists, the joining day deletion, execution in step 509.

Step 508, revise in the service lists should business joining day.

Step 509 sends the stage step that joins request at this business execution.

Step 510 judges whether to also have unselected business, if then return step 502, otherwise finishes.

Embodiment three:

In this enforcement, the user is set to occasional service or long-time professional by adding indegree.Present embodiment is provided with a service lists that is used to store the business information of long-time business in UE, its adition process may further comprise the steps: referring to Fig. 6, Fig. 6 is the manual schematic flow sheet that adds the MBMS business of the present invention's the 3rd preferred embodiment.This flow process may further comprise the steps:

Step 601, UE receives the MBMS business that the user selects.

Step 602, the prompting user selects to add type.

Step 603 is provided with the adding type of this business.

Step 604 judges whether to be long-time business, if then execution in step 605; Otherwise execution in step 606.

Step 605, the service identification that this is professional stores in the service lists with business information such as adding indegree.Step 606 sends the stage step that joins request at this business execution.

Step 607, carry out add successfully after, the indegree that adds of this business is subtracted 1.

Step 608 judges whether the professional number of times that this moment should business is less than or equal to 0, if then execution in step 609, otherwise execution in step 610.

Step 609, delete in this service lists should business the indegree that adds, finish.

Step 610, upgrade in the service lists should business the indegree that adds, finish.

Like this, behind the UE cycle power, UE just can directly read the service identification of each long-time MBMS business and add indegree from service lists, then the long-time business in the service lists is carried out three steps that send the stage that joins request one by one, detailed process and Fig. 4 flow process are basic identical, after just each business joins request three steps in stage, carry out above-mentioned steps 607～610 earlier, add next professional again.

In addition, user of the present invention can also be according to individual's hobby to long-time business setting priority, and together be stored in the service lists with this professional business information.

Like this, when restarting after the UE shutdown, UE can read the business information and the priority of each long-time MBMS business from service lists, again according to the order of priority, one by one long-time business is carried out the adition process of described three embodiment.

If user also occasional service is set to lowest priority, so when the user selects to add the MBMS business, UE according to priority order is shown to the user with each MBMS business, the user can select according to the personal like, this helps the user when network can't receive all and joins request, and selects.

By time or number of times the adding type is set respectively in the foregoing description, also can promptly be provided with by the time in an implementation process and also presses the number of times setting, processing procedure is same as the previously described embodiments respectively.
