Description

Method and system for counting user equipment information in multimedia broadcast multicast service

Technical Field

The present invention relates to a User Equipment (UE) feedback technology in a Multimedia Broadcast Multicast Service (MBMS) system, and in particular, to a method and a system for counting UE information in a Multimedia Broadcast multicast service.

Background

In order to efficiently utilize mobile network resources, the third generation partnership Project (3 GPP), a technology for transmitting data from a data source to a plurality of target mobile terminals, proposes an MBMS service, which enables sharing of network (including core and access networks) resources and improves utilization of network resources, particularly air interface resources.

In a Long Term Evolution (LTE) system, when a UE is notified that a certain MBMS service is about to change, the change may be session start, service bearer update, session stop, or the like, a Downlink Control Information (DCI) and an MBMS Radio network temporary Identifier (M-RNTI) may be first sent on a Physical Downlink Control Channel (PDCCH), and then the UE further reads a specific MBMS point-to-multipoint Control Channel (MCCH, MBMS point-to-multipoint Control Channel) message according to related information in the DCI, which is called an MCCH notification (notification Control Channel) mechanism. The MCCH is to transmit specific service configuration parameters, such as a service Identifier (ID), a Radio Link Control (RLC) parameter of a service, a Media Access Control (MAC) parameter, a physical layer configuration parameter, and the like.

In the LTE system, there are two bearer modes for MBMS: a broadcast mode and an enhanced broadcast mode. Without the multicast mode, the network side cannot know which MBMS services the UE receives and/or is ready to receive. The enhanced broadcast is between broadcast and multicast, and the advantages of simple flow in the broadcast and resource optimization in the multicast are absorbed. When using the MBMS enhanced broadcast bearer, registration/deregistration from the UE to a broadcast multicast Service Center (BM-SC) can be achieved only through a join/leave procedure at an application layer without signaling interaction and information storage at a bearer network layer. Enhanced broadcast is an optimization and extension to broadcast, such as in an access network, which does not send data to those cells that do not receive a UE. For the MBMS service in enhanced mode, the state and Number of UEs receiving the MBMS service need to be considered when configuring a System Frame Number (SFN) and allocating resources, so that UE information for receiving/or preparing to receive the MBMS service needs to be fed back, which is called as uplink feedback of MBMS. In order to activate/deactivate a multicast/broadcast single frequency network (MBSFN) transmission mode in 3GPP Rel10MBMS, the network side needs to obtain the receiving status information of the UE, such as the UE number information of the receiving a given MBMS service.

In order to enable the network side to obtain the number of users having the MBMS service requirement in each cell, the MBMS system introduces a counting process.

The counting process refers to a process of counting the number of users receiving and preparing to receive a certain MBMS service in a cell initiated by a network side when a session (session) of the MBMS service starts or during the session (also called counting) process, so as to determine whether to use an MBSFN transmission mode. When the network side prepares to initiate the counting/recounting process, the identification and access probability of the MBMS service are added into the access information (access info) of the MCCH. The reason for using the access probability is that all users are not required to establish a connection for feedback, as long as the feedback quantity may reach a threshold, otherwise, uplink congestion may be caused when there are many Idle (Idle) state users. However, the conventional counting process can only simply count the number of UEs receiving and ready to receive, and cannot provide an accurate reference basis for the adjustment of the service sending method on the network side, and cannot meet the requirement that an operator knows the service acceptance.

the feedback information further comprises one or more of the following: UE receiving capability indication, satisfaction/interest, UE ID, etc., where the UE receiving capability indication is used to indicate the capability of the UE to receive the MBMS service, and may be represented by one bit, and this information is used to improve service continuity during the UE moving process, for example: the network side can switch the UE to the MBSFN cell preferentially according to the information; the satisfaction/interestingness includes: satisfaction, dissatisfaction, interest, disinterest.

The invention is further described in detail below with reference to the figures and the specific embodiments.

The method for counting UE information in MBMS service of the present invention, as shown in FIG. 1, comprises the following steps:

step 101: presetting a triggering condition fed back by the UE;

in this step, a feedback period may be preset, and when the feedback time is up, the UE sends feedback information; or the network side sends a feedback request, and the UE sends feedback information according to the feedback request after receiving the feedback request; or, a feedback event is preset, and when the feedback event occurs, the UE is triggered to send feedback information;

the feedback period can be selected by the UE, or the network side can be designated by RRC message or MAC message; further, the feedback period selected by the UE may be one or more MCCH modification periods or MBMS service channel (MCH) scheduling periods; further, the period is generally less than the duration of the service session;

the feedback event can be session start, session end, bearer change, cell update, or cell handover;

the network side may send the feedback request by instructing the UE to send the feedback information through an RRC message or an MAC message, and preferably, the RRC message may be an MCCH message or a system message;

the feedback request comprises a service identifier, a service state and a probability factor, wherein the service state comprises that a service is in progress, the service is sent and the service is not sent; the probability factor is used for indicating the number of the UE which simultaneously sends the feedback information, if the probability factor is 0.5, the UE which receives the service request randomly takes a value between 0 and 1, and the UE with the value less than 0.5 sends the feedback information; supposing that 3 services in the MBSFN area need to be subjected to feedback statistics, wherein the service A is transmitting through the MBSFN, the service B does not start the MBSFN transmission yet, and the MBSFN transmission of the service C is finished; PF-a indicates a probability factor for controlling the number of UEs that simultaneously transmit feedback information for service a; PF-B indicates a probability factor for controlling the number of UEs that simultaneously transmit feedback information for service B; PF-C indicates a probability factor for controlling the number of UEs that simultaneously transmit feedback information for service C; the feedback request is shown in table 1:

service identification	Traffic state	Probability factor
			A	The business is ongoing	PF-A
B	The service has not been sent	PF-B
			C	The service has already been sent	PF-C

TABLE 1

In the above, after triggering the UE feedback, the UE may continue to send feedback information according to the feedback cycle, or trigger the feedback according to the feedback event.

Step 102: the UE sends feedback information to a network side according to the trigger condition;

in this step, the UE refers to a UE with MBMS receiving capability, and may be in an RRC connected state or an RRC idle state, and may be receiving a service or not receiving a service;

the feedback information includes: service identification, and at least one of the following UE state and area identification;

the UE status may be at least one of: received, not received, ready to receive, receiving, stopping receiving, receiving a bearer change, cell update, cell switch, etc.; the area identification is: MBSFN area ID or notification indication; the service identification comprises: TMGI, and/or MBMS service ID, and/or PMCH ID, and/or LCID, and/or session ID, and/or service list index, and/or service navigation identifier, etc.;

the feedback information further comprises one or more of the following: the UE receiving capability indication is used for indicating the capability of the UE for receiving the MBSFN transmission, can be represented by one bit and is mainly used for improving service continuity in the UE moving process; the satisfaction/interestingness includes: satisfaction, dissatisfaction, interest and disinterest, wherein four options of satisfaction, dissatisfaction, interest and disinterest are provided through an interface and are selected by a user;

for example, assume that there are 3 services in the MBSFN area that need to perform feedback statistics, where service a is transmitting through MBSFN, service B has not started MBSFN transmission yet, and MBSFN transmission of service C has ended; UE-1, 2, 3 has MBSFN reception capability, UE-4 has no MBSFN reception capability:

(1) UE-1 is receiving service A through MBSFN, UE-1 is interested in receiving service B, UE-1 has not received service C, and the feedback information of UE-1 is shown in Table 2:

service identification	UE identity	UE status	UE reception capability indication	Satisfaction/interest
					A	1	Is receiving	1	Satisfaction
B	1	Has not received	1	Of interest
					C	1	Has not received	1	Is not interested in

TABLE 2

(2) UE-2 just enters the MBSFN area, does not receive service A through the MBSFN (receives service A through unicast), UE-2 is not interested in receiving service B, and UE-2 receives service C; the feedback information of UE-2 is shown in Table 3:

service identification	UE identity	UE status	UE reception capability indication	Satisfaction/interest
					A	2	Cell update	1	Of interest
B	2	Has not received	1	Is not interested in
					C	2	Has received	1	Is not satisfied with

TABLE 3

(3) UE-3 does not receive service A, UE-3 is interested in receiving service B, UE-3 has received service C, and the feedback information of UE-3 is shown in Table 4:

service identification	UE identity	UE status	UE reception capability indication	Satisfaction/interest
					A	3	Ready to receive	1	Of interest
B	3	Has not received	1	Of interest
					C	3	Has received	1	Satisfaction

TABLE 4

(4) UE-4 receives service A through unicast, UE-4 is interested in receiving service B, UE-4 has not received service C, and the feedback of UE-4 is shown in Table 5:

service identification	UE identity	UE status	UE reception capability indication	Satisfaction/interest
					A	4	Has not received	0	Of interest
B	4	Has not received	0	Of interest
					C	4	Has not received	0	Is not interested in

TABLE 5

Generally, the feedback information of the UE is carried in at least one of the following: RRC connection request information, or RRC connection reconfiguration complete information, or RRC connection reestablishment request information, or RRC connection reestablishment complete information, or connection establishment complete information, or cell update information, or random access request information, or measurement report, or media access control element (MAC CE);

when the UE is triggered according to a trigger condition and sends feedback information to a network side, if the UE is scheduled, the UE sends the feedback information through the existing uplink resource, otherwise, the UE requests the uplink resource to send the feedback information through a Scheduling Request (SR) or a Buffer Status Report (BSR);

further, in this step, when the UE sends the feedback information to the network side according to the trigger condition, the UE prompts the user whether to close the feedback function, and when the user selects to close, the UE does not send the feedback information, that is, the user may determine whether to participate in the feedback.

Step 103: the network side carries out statistics on the feedback information;

specifically, the network side performs statistics according to feedback information of the UE within a period of time; the period of time is within the duration of the service session, namely the period of time is less than the duration of the service session; the period of time may be indicated by a timer, that is, when the UE feedback starts, the timer is started, and when the timer is 0, the network side stops receiving the feedback information.

The network side performs statistics on the feedback information, for example: the network side counts the number of the UE in different states under each service according to the UE state, the area identification and the service identification in the feedback information; further, if the feedback information also includes satisfaction/interest, the satisfaction/interest of the user to each service can be counted;

in the period of time, if the network side does not receive the UE feedback information, the network side considers that the UE stops receiving or is not ready to receive the MBMS service; in the period of time, the network side receives a plurality of feedback information of the same UE, and the network side can count the feedback information once;

further, if the system of the MBMS service further includes UEs before Rel-10 system, such as Rel-9 UEs, since Rel-9 UEs have no feedback capability, but a scaling factor can be determined by the ratio of Rel-9 UEs to Rel-10 UEs in the system of the MBMS service, so as to approximately estimate the number of UEs in all MBMS service in the system.

Step 104: the network side adjusts the service sending mode according to the statistical result;

specifically, the network side adjusts the service sending mode according to the counted number of the UEs in different states under each service, for example, when the number of the UEs in a certain service and in a state of being prepared for receiving and being received is larger than a preset threshold value, the network side activates MBSFN transmission for the service, and conversely, when the number of the UEs in a certain service and in a state of being prepared for receiving and being received is smaller than a preset threshold value, the network side deactivates MBSFN transmission for the service; further, the network side adjusts the service sending mode according to the counted capability of the UE for receiving the MBSFN transmission and the satisfaction/interest degree of the user to each service;

the transmission mode adjustment refers to the activation or deactivation of MBSFN transmission by a network side; the activating MBSFN transmission refers to transmitting the MBMS service in an MBSFN mode in an MBSFN area, and the deactivating MBSFN transmission refers to stopping transmitting the MBMS service in the MBSFN area. The service for deactivating MBSFN transmission can be continuously transmitted in a unicast mode;

the deactivation of MBSFN transmission generally needs to inform the UE in advance, and generally cannot influence the existing service session process;

for the UE in the RRC Idle state before deactivation, the UE in the RRC Idle state may be transferred to the RRC Connected state through RRC signaling or other high layer signaling, so that the UE continues to receive the service in a unicast manner after deactivation.

In order to implement the above method, the present invention further provides a system for counting UE information in an MBMS service, as shown in fig. 2, the system includes: at least one UE21, a network side 22; wherein,

in this step, the UE obtains the UE state of the service corresponding to the service identifier according to the service identifier in the feedback request, and sends feedback information to the network side; the feedback information includes: UE state, area identification and service identification; the UE status may be at least one of: received, not received, ready to receive, receiving, stopping receiving, receiving a bearer change, cell update, cell switch, etc.; the area identification is: MBSFN area ID or notification indication; the service identification comprises: TMGI, and/or MBMS service ID, and/or PMCH ID, and/or LCID, and/or session ID, and/or service list index, and/or service navigation identifier, etc.;

the feedback information further comprises one or more of the following: UE reception capability indication, satisfaction/interest, UE ID, etc., where the UE reception capability indication is used to indicate a capability of the UE to receive the MBSFN transmission and may be represented by one bit; the satisfaction/interestingness includes: satisfaction, dissatisfaction, interest and disinterest, wherein four options of satisfaction, dissatisfaction, interest and disinterest are provided through an interface and are selected by a user;

Step 403: the network side carries out statistics on the feedback information;

Step 404: the network side adjusts the service sending mode according to the statistical result;

Example three:

in this embodiment, after the MBMS service is finished, the UE sends the feedback information, where the finished MBMS service means that MBSFN transmission of the MBMS service is finished, but the service may also be in unicast transmission, so as to implement a method for counting UE information in the MBMS service, as shown in fig. 5, the method includes the following steps:

step 501: setting the time for sending the feedback request at a network side in advance, and sending the feedback request at the time of the time by the network side;
