What is transmitted between the SGW of PGW-s and UE attachment is the content of the scheduled unicast services of the UE.Between PGW-s and UE There are corresponding relationship, a PGW-s can provide unicast services for each SGW the being connected thereto UE connected." second PGW " is the PGW of the content of the unicast services of transmission objectives UE.

It should be noted that may include one or more PGW-g in a system, and one or more PGW-s；Its In, any one PGW-g and any one PGW-s can be two independent functional modules in same equipment, or Two independent equipment.

It referring to fig. 2, is the system architecture schematic diagram of transmission unicast services and multicast services provided in an embodiment of the present invention.Figure System shown in 2 include: GCS AS, the one or more PGW-g being connect with GCS AS, one connect with GCS AS or Multiple PGW-s, and the one or more SGW being connect with each PGW-s.In addition, multiple PGW-s also can connect it is same SGW, a SGW can connect one or more UE.It should be noted that when specific implementation, with the movement of UE, each PGW- G may send the content of multicast services to any SGW, therefore theoretically, each PGW-g can connect with the SGW in system It connects.Certainly, in actual implementation, specific PGW-g can also be connect with specific one in system or multiple SGW.

2), the first PCRF (Policy and Charging Rules Function, "Policy and Charging Rules Function) and 2nd PCRF

Each PGW is managed by a PCRF, and in the embodiment of the present invention, the PCRF for managing PGW-g is known as group It broadcasts service and the PCRF, i.e. PCRF-g of session management is provided；It is known as the PCRF for managing PGW-s to provide session management for unicast services PCRF, i.e. PCRF-s.

PCRF-g manages PGW-g, can specifically include: PCRF-g determines the PGW-g of one multicast services of transmission；Alternatively, PCRF-g instruction PGW-g establishes multicast services etc..One PCRF-g can manage one or more PGW-g.One PCRF-g with There are corresponding relationship, a PCRF can provide session management for one or more multicast services for multicast services." the first PCRF " It is to provide the PCRF-g of session management for target multicast services.

PCRF-s manages PGW-s, can specifically include: PCRF-s establishes PCC (Policy and to PGW-s instruction Charging Control, strategy and charging control) rule；Alternatively, sending information etc. to SGW by PGW-s.One PCRF-s One or more PGW-s can be managed.One between PCRF-s and UE there are corresponding relationship, a PCRF-s can be to be attached to The unicast services for the UE on each PGW-s that the PCRF-s is managed provide session management." the 2nd PCRF " is for target UE Unicast services provide session management PCRF-s.

3), "and/or" herein is only a kind of incidence relation for describing affiliated partner, indicates that there may be three kinds of passes System, for example, A and/or B, can indicate: individualism A exists simultaneously A and B, these three situations of individualism B." multiple " are Refer to two or more.

It should be noted that specific implementation when, transmitting terminal herein to receiving end send any one request message it Afterwards, it can receive the corresponding response message of the request message of receiving end reply.Wherein, transmitting terminal here and receiving end It can be any one equipment herein respectively.

Referring to Fig. 3, the system architecture schematic diagram controlled for a kind of pair of multicast services provided in an embodiment of the present invention.Its In, " control " here includes: policy control and/or charging control etc..System shown in Fig. 3 includes: for target multicast services First PCRF of session management is provided；In addition it can the first PGW including GCS AS and the content of transmission objectives multicast services.

First PCRF, for receiving the mark of the target multicast services from GCS AS, and according to target multicast services It identifies and determines the first PGW；So that the content of received target multicast services is sent to by the first PGW subscribes target multicast services Target UE.

Wherein, the first PCRF can receive the mark of the target multicast services from GCS AS by direct or indirect mode Know.One PCRF-g can manage one or more PGW-g, therefore one or more PGW- that the first PCRF needs to manage from it The PGW-g, i.e. the first PGW of the content of transmission objectives multicast services are determined in g.

First PGW received target multicast services content, may include: the first PGW receive GCS AS send mesh Mark the content of multicast services.Specific: the first PGW receives the content of the target multicast services of GCS AS push.Under present case, If having been set up target multicast services in system, the first PGW is receiving the target multicast services of GCS AS push Content；If can realize the first PGW according to hereafter optional implementation there are no target multicast services are established in system Receive the purpose of the content of the target multicast services of GCS AS push.

" subscribing the target UE of target multicast services " can be subscribe target multicast services any one or more UE.One UE can make a reservation for one or more multicast services, " target multicast services " can for target UE it is scheduled any one Multicast services." marks of target multicast services " can be that (Temporary Mobile Group Identity, faces for TMGI When mobile group designation) or TMGI and Flow ID (traffic identifier) combination.

Above provide the systems that a kind of pair of multicast services are controlled.

Due to not distinguishing the PGW of transmission unicast services and the PGW of transport multicast service in the prior art, that is to say, that same The scheduled all unicast services of one UE and all multicast services pass through the PGW that the UE adheres to and are transferred to the UE.It therefore can be with Deduce a kind of technical solution of possible control multicast services: GCS AS adheres to each UE for subscribing same multicast services PGW send the contents of the multicast services；Each PGW of the content of the multicast services is received to connected to it each attached The content for thering is the SGW for the UE for subscribing the multicast services to send the multicast services；Receive the every of the content of the multicast services A SGW sends the content of the multicast services to the UE for subscribing the multicast services attached thereto respectively.Wherein, a UE is attached PGW refer to the PGW connected when UE access PDN；The PGW not only provides unicast services for the UE but also provides multicast services.

In the above-mentioned technical solution deduced, as multiple same SGW of PGW connection, if being attached on multiple PGW Multiple UE subscribe the same multicast services, and multiple UE is attached on the same SGW, then in multiple PGW Each PGW can send the content of the multicast services to the SGW, that is to say, that and the SGW can receive duplicate information, thus Lead to the waste of Internet resources.

And the present invention is implemented in the system controlled multicast services provided, is determined and is passed according to the mark of multicast services The PGW of the defeated multicast services, that is to say, that the content of the same multicast services is transmitted by the same PGW.In this way, predetermined The SGW of the UE attachment of one multicast services would only receive the interior of the multicast services for transmitting that the PGW of the multicast services is sent Hold, therefore be able to solve in the above-mentioned technical solution deduced, because the same SGW can receive same group that multiple PGW are sent The problem of broadcasting the waste of Internet resources caused by the content of service.

The first PCRF in above system may include memory, receiver, processor and system in hardware realization Bus；It wherein, between memory, receiver and processor is coupled by bus system, wherein bus system is removed It can also include power bus, control bus and status signal bus in addition etc. except data/address bus.

Receiver, for receiving the mark of the target multicast services from GCS AS.

Memory, for storing one group of code；The code is true according to the mark of target multicast services for control processor Fixed first PGW；So that the content of received target multicast services is sent to by the first PGW subscribes the target of target multicast services UE。

Wherein, memory may include high speed RAM memory, it is also possible to further include nonvolatile memory (non- Volatile memory), a for example, at least magnetic disk storage.Processor can be CPU (Central Processing Unit, central processing unit), microprocessor, single-chip microcontroller etc..

It should be noted that the function in conjunction with performed by the first PCRF in following systems, in hardware realization, this first PCRF can also include transmitter, which is used to send communication data to other equipment (such as the first PGW etc.).Transmitter It can be individually present with receiver, can also close and set composition transceiver.

Optionally, as shown in fig. 4 or 5, which can also include the SGW of target UE attachment；In this case, the first PGW, It is specifically used for: sends the content of target multicast services to SGW using target multicast bear, so that SGW utilizes target EPS (Evolved Packet System, evolved packet system) carries the content that target multicast services are sent to target UE.

Wherein, " target multicast bear " refers to required when the transmission objectives multicast services established between the first PGW and SGW The multicast bear wanted.Multicast bear is one-to-one with multicast services.Under present case, target multicast bear may have been deposited , it is also possible to it is not present；If it does not exist, then need to establish target multicast bear, specific implementation process can be with reference to hereafter.It needs It is noted that need using target multicast services as multiple UE, and when multiple UE is connected on multiple SGW, need the Multicast bear is established respectively between one PGW and multiple SGW.

" target EPS carrying " refer to established between SGW and target UE to target UE transmission objectives multicast services when it is required The EPS carrying wanted.EPS carrying is one-to-one with UE.Under present case, target multicast bear may be had existed, can also It can be not present；If it does not exist, then need to establish target EPS carrying, specific implementation process can be with reference to hereafter.It needs to illustrate It is, when multiple UE under a SGW are needed using target multicast services, to need to build respectively between the SGW and multiple UE Vertical EPS carrying.

For example, it is assumed that having 3 UE, i.e. UE1, UE2 and UE3, need using target multicast services, and UE1 is connected to On SGW1, UE2 and UE3 are connected on SGW2, and the PGW-g of transmission objectives multicast services is PGW-g1；So, it needs in PGW-g1 Target multicast bear is established between SGW1 and between PGW-g1 and SGW2, and between SGW1 and UE1, SGW2 and UE2 Between and SGW2 and UE3 between establish corresponding target EPS carrying respectively.

Optionally, each equipment in the system can be by executing following manner 1,2,3, to realize that the first PCRF is received The mark of target multicast services from GCS AS.Wherein, in mode 1,2, session pipe is provided by the unicast services of target UE 2nd PCRF of reason determines the first PCRF；In mode 3, the first PCRF is determined by GCS AS.

Mode 1: the first PCRF is determined by the 2nd PCRF, and the first PCRF and the 2nd PCRF are independent two equipment.Such as Shown in Fig. 4, by a kind of applicable system architecture schematic diagram of mode 1.

In this approach, each equipment in the system is for executing following functions:

GCS AS for receiving the request message using target multicast services from target UE, and will use target group The request message for broadcasting service is sent to the 2nd PCRF；Wherein, using including target UE in the request message of target multicast services The mark of mark and target multicast services.

2nd PCRF, for being mentioned according to the mark and preset multicast services of target multicast services with for multicast services For the corresponding relationship of the PCRF of session management, the first PCRF is determined；And the mark of target multicast services is sent to the first PCRF.

For example, when a UE is needed using some multicast services, it includes the UE which can send to GCS AS Mark and the multicast services mark the request message using target multicast services；Wherein, which is target UE, the group Broadcasting service is target multicast services.

" mark of target UE " can be any one character or character string for being capable of different UE in compartment system.Example Such as, (Internet Protocol, the network protocol) address IP of target UE or the IP address of target UE be can be and connect The combination etc. for receiving the port numbers of the content of target multicast services, is also possible to the information for the mark that other can obtain target UE, The present invention is without limitation.It should be noted that when not including the end for receiving the content of target multicast services in the mark of target UE When slogan, the SGW of UE attachment can send the content of target multicast services to the port numbers of a default of target UE；Wherein, What the port numbers of the default can be appointed in advance for SGW and target UE.

It can also include QoS (Quality of Service, Service Quality in " using the request message of target multicast services " Amount), the QoS for needing to meet when which is the content of transmission objectives multicast services.Illustratively, which specifically includes following letter One or more of breath: the bandwidth requirement, delay requirement of required satisfaction, the bit error rate when content of transmission objectives multicast services It is required that etc..

It should be noted that may include one or more PCRF-g in system, a multicast clothes are capable of providing in system , can be according to the corresponding PCRF-g of the good multicast services of certain rule settings when business, and store the multicast services and the PCRF- Corresponding relationship between g.In this way, the 2nd PCRF can be when receiving the request message using target multicast services, according to this Corresponding relationship determines the corresponding PCRF-g of the mark of target multicast services, i.e. the first PCRF.

2nd PCRF can directly take according to target multicast after receiving the request message using target multicast services The corresponding relationship of the mark of business and preset multicast services and the PCRF that session management is provided for multicast services, determines first PCRF.2nd PCRF can also be after receiving the request message using target multicast services, it is first determined whether authorizes mesh It marks UE and uses target multicast services；Then after determining authorization, according to the mark of target multicast services and preset multicast The corresponding relationship of service and the PCRF that session management is provided for multicast services, determines the first PCRF；And it replys and authorizes to GCS AS Target UE uses the response message of target multicast services.In addition, however, it is determined that do not authorize, then do not authorize target UE to GCS AS reply Use the response message of target multicast services.Illustratively, the 2nd PCRF determines whether that target UE is authorized to take using target multicast Business, can specifically include: the 2nd PCRF determines whether target UE has contracted, i.e., whether subscribes target multicast services；With/ Or, the 2nd PCRF determines whether system is capable of providing the target multicast services for meeting certain QoS under present case, wherein the QoS It can be the QoS carried in the request message using target multicast services, or the QoS defaulted in the 2nd PCRF.

Mode 2: the first PCRF is determined by the 2nd PCRF, and the first PCRF and the 2nd PCRF are the same equipment, specifically Independent two functional modules in the same equipment.As shown in figure 5, a kind of system architecture schematic diagram being applicable in by mode 2.

2nd PCRF, for being mentioned according to the mark and preset multicast services of target multicast services with for multicast services It for the corresponding relationship of the PCRF of session management, determines that the 2nd PCRF is to provide the PCRF of target multicast services, that is, determines second PCRF and the first PCRF is same equipment.

In mode 2, the 2nd PCRF is identical as the first PCRF, in this case, the first PCRF receive from GCS AS The mark of target multicast services, specifically: the 2nd PCRF (or the first PCRF) receives the use target multicast that GCS AS is sent and takes The request message of business.

Mode 3: the first PCRF is determined by GCS AS.

GCS AS, for receiving the request message using target multicast services from target UE, wherein use target group Broadcast the mark of the mark and target multicast services in the request message of service including target UE；And according to the mark of target multicast services The corresponding relationship of knowledge and preset multicast services and the PCRF that session management is provided for multicast services, determines the first PCRF, and The mark of target multicast services is sent to the first PCRF.

It should be noted that can also include the 2nd PCRF, the system architecture being applicable in the system in mode 3 Schematic diagram can be as shown in Figure 5 or Figure 6.In this case, being based on system shown in fig. 6, the first PCRF is also used to the 2nd PCRF The request message for using target multicast services is sent, so that the 2nd PCRF can be realized according to content provided below to multicast The control of service.

Optionally, it when the first PCRF determines a PGW according to the mark of target multicast services, can specifically include: according to The mark of target multicast services, it is determined whether establish target multicast services；If establishing target multicast services, transmission is inquired The PGW of target multicast services, and using the PGW inquired as the first PGW；If not establishing target multicast services, according to pre- If rule determines the first PGW.

It should be noted that when GCS AS receives the content request message of some multicast services of PGW-g transmission Later, the content of the multicast services can be just pushed to the PGW-g.And a PGW-g is to receive the management PGW-g What PCRF-g was issued establishes after the instruction message of the session of the multicast services, can just trigger to GCS AS and send the multicast services Content request message.Also, works as PGW-g and send the content request message of the multicast services to GCS AS, and receive this and ask After asking message to correspond to response message, that is, think to have been set up the multicast services.Therefore, PCRF-g is able to know whether to establish Its corresponding each multicast services, i.e. the first PCRF are able to know whether to have been set up target multicast services.Further, First PCRF can inquire the PGW-g (i.e. the first PGW) of transmission objectives multicast services.

For example, if under present case, there is the UE that target multicast services are used in system, then in system Establish target multicast services；If under present case, it, then may be there is no the UE of target multicast services is used in system Target multicast services are had been set up before present case, but has been cancelled or has not been cancelled also, it is also possible to from not setting up Cross target multicast services.

First PCRF directly can determine first according to preset rules after target multicast services are not established in determination PGW.Whether the first PCRF can also be after target multicast services not be established in determination, it is first determined authorize and establish target multicast Service；Then after determining that target multicast services are established in authorization, the first PGW is determined according to preset rules.Wherein, the first PCRF The loading condition etc. for some or all PGW-g that can be managed according to it, it is determined whether target multicast services are established in authorization. " the first PCRF determines the first PGW according to preset rules " specifically may be implemented are as follows: the first PCRF is according to the principle etc. of load balancing A PGW-g for selecting it to be managed is as the first PGW.

Based on the optional implementation, further, the first PCRF is also used to executing according to preset rules determination After first PGW, the request message for establishing the session of target multicast services is sent to the first PGW；First PGW is for receiving It establishes after the request message of the session of target multicast services, the content request message of target multicast services is sent to GCS AS； Wherein, the content request message of target multicast services is used to indicate the content that GCS AS sends target multicast services to the first PGW.

It should be noted that the request message for establishing the session of target multicast services, which is used to indicate the first PGW, establishes first Communication tunnel between PGW and GCS AS；GCS AS disappears in the content requests for the target multicast services for receiving the first PGW transmission After breath, the corresponding response message of the request message can be replied to the first PGW；About target between first PGW and GCS AS The content request message of multicast services, and the optionally interactive process about the corresponding response message of the request message Establishment process with the communication tunnel being considered between the first PGW and GCS AS.

The further alternative implementation it also will be understood that are as follows: the first PCRF indicate the first PGW establish target multicast clothes The process of business.Since the process is related with the mark of target multicast services, and it is unrelated with the mark of target UE, therefore, theoretically, When subscribing any UE application of target multicast services using target multicast services, the first PCRF can indicate that the first PGW is built Vertical target multicast services；In fact, when the first PCRF can one of UE application use target multicast services when, establish target Multicast services, and when subsequent UE application uses target multicast services, directly use target multicast services.

In the further alternative implementation, when first in all UE that target UE is predeterminated target multicast services Apply for the UE of target multicast services, and this application (i.e. this sends to GCS AS and uses request message) is that the UE applies for the first time When target multicast services, target multicast services are not set up in system also.That is, technical side provided in an embodiment of the present invention Case allows not establish in the case where having UE to subscribe target multicast services and using target multicast services without UE application Target multicast services；When having UE application using target multicast services, target multicast services are just established, money can be saved in this way Source.This point is different from the technical solution deduced, wherein as long as there is UE to subscribe target multicast in the technical solution deduced Service, system just need to establish target multicast services, and continuously send to all UE for subscribing target multicast services The content of target multicast services.

In the concrete realization, as one embodiment, the first PGW can be also used for establishing target multicast services receiving Session request message after, be target multicast services reserved target multicast load-bearing resource；And target is being sent to GCS AS After the content request message of multicast services, the corresponding response of request message for establishing target multicast services is replied to the first PCRF Message.Wherein, establish may include in the session request of multicast services target multicast services mark；Optionally, it can also wrap Include mark and/or the QoS of target multicast bear etc. of GCS AS.Wherein, the QoS of target multicast bear can be with are as follows: uses target Entrained QoS in the request message of multicast services；Specifically, GCS AS receives the request message using target multicast services In entrained QoS, and the first PGW is transferred to through the first PCRF, alternatively, being transferred to first through the 2nd PCRF and the first PCRF PGW。

Illustratively illustrate that target multicast bear is established in triggering, target EPS carrying is established in triggering below, and triggering is established The process of binding relationship between target multicast bear and target EPS carrying:

The process of target multicast bear is established in triggering:

2nd PCRF is also used to after the mark for getting the first PGW, the content of the unicast services through transmission objectives UE The 2nd PGW to SGW send the first PGW mark；So that SGW determines whether establish target multicast between SGW and the first PGW Carrying, and when target multicast bear is not established in determination, establish target multicast bear.

Wherein, the 2nd PCRF obtains the mark of the first PGW, specifically may be implemented are as follows: if the first PCRF and the 2nd PCRF is Two independent equipment, then the 2nd PCRF receives the mark for the first PGW that the first PCRF is sent；If the first PCRF and the 2nd PCRF It is the same equipment, then the 2nd PCRF (i.e. the first PCRF) determines the mark of the first PGW according to the mark of target multicast services.

It should be noted that being generally not provided with communication interface between PCRF-s and SGW, need to lead between PCRF-s and SGW PGW is crossed to carry out information exchange；It is unrelated with UE since PGW-g is the PGW of transport multicast service, i.e., it cannot identify UE, therefore It cannot know which SGW UE is connected on, and PGW-s is the PGW for transmitting unicast services, can identify UE, therefore can know Which SGW UE is connected on, it follows that information exchange can be carried out between PCRF-s and SGW by PGW-s, i.e., second Information exchange is carried out by the 2nd PGW between PCRF and SGW.Similar, since PCRF-g is used for managing PGW-g, PCRF-s In management PGW-s, therefore, PCRF-g, which cannot be identified, can carry out information by PCRF-s between PGW-s, PCRF-g and PGW-s Interaction carries out information exchange by the 2nd PCRF that is, between the first PCRF and the 2nd PGW.

If under present case, there is the UE that target multicast services are used in system, then have been set up mesh in system Mark multicast bear；If, then may be in present case there is no the UE that target multicast services are used in system under present case Target multicast bear is had been set up before, but has been released or has also been not released, it is also possible to from not setting up mark group of looking over so as to check Broadcast carrying.

SGW establishes target multicast bear, can specifically include: SGW sends the control for establishing target multicast services to the first PGW The request message of Area Objects multicast bear processed and user's Area Objects multicast bear, so as to establish target group between the first PGW and SGW Broadcast carrying.Further, the QoS of the target multicast bear according to received by the first PGW establishes target multicast bear.

The process of target EPS carrying is established in triggering:

2nd PCRF is also used to after the request message using target multicast services for receiving GCS AS transmission, to 2nd PGW of the content of the unicast services of transmission objectives UE send PCC (Policy and Charging Control, strategy with Charging control) rule, it is carried so that the 2nd PGW establishes target EPS according to PCC rule；It wherein, include target UE in PCC rule Mark and target multicast services mark.

Wherein, the 2nd PGW establishes target EPS carrying, can specifically include: the 2nd PGW establishes target EPS to SGW transmission The request message of carrying, wherein include PCC rule in the request message；So that between SGW and the 2nd PGW and SGW with Target EPS carrying is established between target UE respectively.

It can also include the QoS etc. of target EPS carrying in PCC rule, wherein the QoS can be to be taken using target multicast Entrained QoS in business.

It should be noted that needing to establish target EPS carrying between SGW and target UE when specific implementation, it is also desirable to Target EPS carrying is established between SGW and the 2nd PGW, but in technical solution provided in an embodiment of the present invention, only utilizes SGW The target EPS carrying established between target UE.And due to being built between SGW and target UE and between SGW and the 2nd PGW Vertical target EPS carrying is an overall process, as long as therefore determining whether that establishing target EPS between SGW and the 2nd PGW holds It carries, that is, can be determined whether to establish target EPS carrying between SGW and target UE.

It is further to note that when SGW1 (SGW being outlined above) detects that the range that UE is covered from it is moved When moving in the range of another SGW (following be known as SGW2) covering, above-mentioned PCC rule can be sent to SGW2 so that SGW2 with Required EPS carrying when the content of transmission objectives multicast services is established between 2nd PGW.The process is properly termed as EPS carrying Handoff procedure.In addition, SGW1 can be after handoff procedure completion, delete target multicast bear and target EPS carry it Between binding relationship.Further, when none of EPS carrying is bound with target multicast bear, SGW1 can be with Discharge target multicast bear.

The embodiment of the present invention establishes target EPS carrying to triggering and triggers the elder generation between the process for establishing target multicast bear Sequence is without limiting afterwards.

The process of the binding relationship between target multicast bear and target EPS carrying is established in triggering:

2nd PCRF is also used to after the request message using target multicast services for receiving GCS AS transmission, to 2nd PGW of the content of the unicast services of transmission objectives UE sends the request message for using target multicast services；So that the 2nd PGW Bind-request message is sent to SGW；Wherein, the mark of the mark in bind-request message including target UE and target multicast services The mark of the mark and/or target EPS of knowledge and target multicast bear carrying, for making SGW according to bind-request message, In After establishing target multicast bear and target EPS carrying, the mark of bound targets UE, the mark of target multicast services, target The mark of mark and target the EPS carrying of multicast bear.

Wherein, the 2nd PGW sends bind-request message to SGW, and can specifically include: the 2nd PGW is establishing target group After broadcasting at least one of carrying and target EPS carrying, bind-request message is sent to SGW." establishing target multicast bear " And/or " establish target EPS carrying " can be and be established in above-mentioned optional implementation, can also target UE to What GCS AS had had built up when sending using target multicast services.

Above provide target UE application using target multicast services scene under, each module or entity device in system The function that can be realized；Illustrate that the field of target multicast services is cancelled using target multicast services and cancelled in target UE request below Under scape, function that each equipment in system can be realized:

Cancel the scene for using target multicast services:

2nd PCRF is also used to receive the request message that the cancellation from target UE uses target multicast services；And to biography 2nd PGW of the content of the unicast services of defeated target UE sends the request message cancelled and use target multicast services；So that second PGW according to cancel use target multicast services request message, to SGW send release target EPS carry request message and/or The request message of delete target multicast bear and the binding relationship of target EPS carrying；Wherein, the request of release target EPS carrying Message, for making the SGW release target EPS carrying, delete target multicast bear is asked with the target EPS binding relationship carried Ask message for making SGW delete the binding relationship.

Wherein, when target UE do not use target multicast services when, can to GCS AS send including target UE mark and The cancellation of the mark of target multicast services uses the request message of multicast services；Wherein, cancel and being disappeared using the request of multicast services Content of the breath for requesting no longer to receive the target multicast services that GCS AS is provided.GCS AS can be sent to the 2nd PCRF to be cancelled Use the request message of target multicast services.The optional implementation can be improved the flexibility that UE uses multicast services, together When can save resource.

Further, the first PCRF is also used to receive the cancellation from target UE and is disappeared using the request of target multicast services Breath；And according to the request message cancelled using target multicast services, when determining no any UE using target multicast services, to First PGW sends the request message of release target multicast bear, so that the first PGW discharges target multicast bear.

Wherein, the first PCRF can be received the cancellation that GCS AS is sent and be taken using target multicast directly or through the 2nd PCRF The request message of business.The further alternative implementation discharges target group when no any UE uses target multicast services Service is broadcast, resource can be saved in this way.

Cancel the scene of target multicast services:

First PCRF is also used to receive BM-SC (Broadcast Multicast-Service Centre, broadcast multi-broadcasting Service centre) or the expired notification message of mark of target multicast services that sends of the first PGW；And according to the notification message to Two PCRF send the request message for cancelling target multicast services.

2nd PCRF, the 2nd PGW for being also used to the content of the unicast services through transmission objectives UE is sent to SGW cancels target The request message of multicast services；So that SGW is according to the request message for cancelling target multicast services, delete target multicast bear and mesh Mark the binding relationship of EPS carrying.

For example, the mark of multicast services is GCS AS to BM-SC application, and the mark of multicast services is general only one Periodically come into force in limit.When specific implementation, the first PCRF or the first PGW can be to the expired things of mark of BM-SC subscription multicast services Part；In this way, when BM-SC determine target multicast services mark it is expired when, can be sent to the first PCRF or the first PGW and cancel target The instruction message of multicast services.Wherein, when the first PGW subscribes to the mark expired events of multicast services to BM-SC, the first PGW The instruction message can be sent to the first PCRF when receiving the instruction message of cancellation target multicast services of BM-SC transmission. It is, moreover, an optional that can also include cancelling the reason of target multicast identifies, the i.e. mark of target multicast services in the instruction message It is expired.

Further alternative, the first PCRF is also used in the target multicast services for receiving BM-SC or the first PGW transmission The expired notification message of mark after, the request message of release target multicast bear is sent to the first PGW；So that the first PGW Discharge target multicast bear.
