The present invention relates to a terminal paging determination method in an FA assigned to a mobile communication broadcast service. More specifically, when processing a paging message (Page Message) to deliver packet data to the terminal in a frequency assignment (FA) assigned for broadcasting / multicast service (BCMCS) information of the terminal (current BCMCS service of the And then determine whether or not to deliver the paging message.

The broadcasting service is expected to be implemented according to the development of mobile communication technology. In the synchronous network centered on CDMA (Code Division Multiple Access), broadcasting service is planned to be implemented through BCMCS (Broadcast / Multicast Service) in 1xEV-DO network in 2005.Asynchronous network centered on WCDMA MBMS is progressing mainly in

In 2004, satellite DMB, which uses broadcast satellites, is scheduled to be commercialized. Among them, BCMCS is briefly described as follows.

BCMCS (Broadcast / Multicast Service) is a service that provides the same information (multimedia including streaming, text message, voice, etc.) to multiple users through one link, and eliminates repeated transmission of the same information in a wireless section. .

In general terms, the distinction between Broadcast Service (BCS) and Multicast Service (MCS) is that MCS user groups have a limited membership, which requires membership to be a member of a specific user group, and information is sent only to subscribed members. Is the form.

BCS is a service that transmits information in the form of broadcasting on a boundary of a specific area (cells, sectors, etc.). For example, location information and traffic information based on a specific area may be used. Divided into

BCMCS began discussions with domestic operators who built the 1X EV-DO network, Japan's KDDI, Qualcomm, and Samsung Electronics, insisting on the need for BCMCS in the 1X EV-DO system. Is in.

Like the existing 1xEV-DO service, the BCMCS service provides a plurality of broadcast service contents, such as a time division multiplex (TDM), by dividing them into time slots in the same FA.

Therefore, a specific slot is transmitted by separating the time slot into a movie channel and another slot into a music channel, and the terminal receives information through an overhead message continuously transmitted by the system before the broadcast service. Check and receive the desired broadcast contents in the slot according to the information.

However, in the conventional mobile communication technology (IS-95, CDMA2000 1X, etc.) there is a limit in providing a broadcast service according to the technical limitations, and thus could not be smoothly provided.

In other words, the prior art scheme fundamentally solves the problem of not being able to accommodate a large number of customers at the same time due to bandwidth limitations as different wireless channels and RP channels (channels from the access network to the PDSN) are allocated to each user. Have

Therefore, the current broadcasting service in the mobile communication network requires a technology for smoothly providing the broadcasting service regardless of the number of customers by minimizing the network resources required for the broadcasting service by setting up a channel for a separate broadcasting service. .

The present invention is to solve the above problems, the present invention is to provide the information of the terminal (current BCMCS) when processing the paging message to deliver the packet data to the terminal in the FA assigned for the broadcast / multicast service (BCMCS) After checking whether the service has been received), the purpose of the present invention is to determine whether paging is delivered or not, thereby minimizing the influence of other terminals receiving the broadcast / multicast service (BCMCS) to provide excellent broadcast service quality. .

As the technical idea for achieving the above object of the present invention

A terminal paging determination method in a mobile communication broadcasting service system,

A first step of receiving packet data at an FA allocated for broadcast / multicast service (BCMCS);

A second step of retrieving information of a corresponding terminal to deliver the received packet data to a terminal;

Determining whether the corresponding terminal receives a current broadcast / multicast service (BCMCS);

As a result, when the terminal is currently receiving a broadcast / multicast service (BCMCS), after searching for a slot that is not allocated in the FA, the terminal determines a paging message in a slot other than the slot allocated for the BCMCS to the terminal. A terminal paging determination method comprising a fourth step of transmitting.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a block diagram of a broadcast / multicast service (BCMCS) system according to the present invention.

1, a mobile station (MS) 10; A base station controller (BSC) / packet control function (PCF) 20; A packet data serving node (PDSN) 30; Authentication, Authorization and Accounting server (AAA) 40; A broadcast / multicast controller (BCMCS Controller) 50; Broadcast / multicast content server (BCMCS Content Server) 60; And broadcast / multicast content provider (BCMCS Content Provider) 70 are configured to interwork with each other.

At this time, the solid line represents the signaling signal line, the dashed-dotted line represents the BCMCS traffic signal line before encryption, and the dotted line represents the BCMCS traffic signal line after encryption.

The packet data serving node (PDSN) 30 supports a protocol for supporting a broadcast service, and plays a role of establishing and releasing a connection with a base station controller (BSC) / packet controller (PCF) 20.

In addition, the mobile station 10 confirms the subscription of the broadcast service from the authentication server (AAA) 40, and permits the base station to allocate the radio channel for the broadcast service and the network resource.

The broadcast / multicast controller (BCMCS Controller) 50 manages subscriber profile information related to a subscription state of the mobile terminal 10, and generates and transmits an authentication key to the corresponding terminal.

The broadcast / multicast content server (BCMCS Content Server) 60 provides multimedia content for broadcasting and encrypts source content.

The broadcast / multicast content provider (BCMCS Content Provider) 70 serves to inform whether a specific broadcast / multicast can be received through HTTP, SAP, SDP, and the like.

In the access network illustrated in FIG. 1, a broadcast service may be provided by assigning a separate FA (Frequency Assignment) according to the degree of broadcast / multicast service (BCMCS), or assigned to an existing 1xEV-DO. The FA can provide broadcast services.

The mobile communication broadcast service of the present invention configured as described above is provided to the customer terminal through the following process.

First, a mobile terminal 10 to receive a broadcast service requests user authentication to the authentication server 40, and the authentication server 40 receives subscriber profile information and broadcast / multicast content from the broadcast / multicast controller 50. Based on whether or not broadcast reception is possible from the provider 70, a broadcast service permission is received as a response thereto.

Then, when the session information for the broadcast service is received from the broadcast / multicast content server 60, the mobile terminal 10 transmits to the broadcast content in order to request the broadcast service to be received from the packet data serving node 30. Related information, that is, BCMCS_ID and multicast IP address, is transmitted to the packet data serving node 30.

When the response to the request is received, the mobile terminal 10 transmits the BCMCS_ID and the multicast IP address to the base station controller / packet controller 20 to register the broadcast service to be received.

In response, the base station controller / packet control unit 20 transmits data for the broadcast service, and the mobile terminal 10 can receive data of the broadcast service to be received.

2 is a flowchart illustrating a terminal paging determination method in an FA allocated to a mobile communication broadcast service according to the present invention.

First, the mobile terminal 10 that wants to receive the broadcast / multicast service (BCMCS) requests user authentication from the authentication server 40, and the authentication server 40 receives subscriber profile information from the broadcast / multicast controller 50. And a broadcast / multicast service permission in response to the broadcast / multicast content provider 70 based on whether broadcast reception is possible.

In this state, FA (Frequency Assignment) allocated for the broadcast / multicast service (BCMCS) in order to deliver the packet data (Packet Data) received from the packet data serving node (PDSN) 30 to the terminal 10; When the paging message is processed, information of the terminal 10 is retrieved (S10 to S20).

In this case, the BCMCS system recognizes a connection state between the terminal and the BCMCS system through a registration process in which the corresponding terminal 10 accesses the system or periodically transmits information, and registers the transmission from the corresponding terminal 10. Through the message, the terminal can know whether the terminal uses the BCMCS service and the terminal information about which content is being received.

In addition, in the access network of the BCMCS system, a broadcast service can be provided by assigning a separate FA according to the degree of broadcasting / multicast service (BCMCS), and the broadcast service can be provided by a FA allocated to the existing 1xEV-DO. Can provide.

Subsequently, by searching for the information of the terminal 10, it is determined whether the terminal 10 is currently receiving a broadcast / multicast (BCMCS) service (S30).

As a result of the determination in step S30, when the terminal 10 is a subscriber currently receiving broadcast / multicast (BCMCS) service, a slot allocated for the broadcast / multicast (BCMCS) (that is, for broadcast content) After allocating slots, transmission slots of overhead messages, etc., and searching for slots that are not allocated for broadcast / multicast (BCMCS) but not slots allocated for BCMCS (S40). In operation S50, a slot for transmitting a paging message to the corresponding terminal 10 is determined.

Thereafter, a paging message is transmitted to the terminal 10 in the determined slot (S60).

As a result of the determination in step S30, the general subscriber that the terminal 10 is not currently receiving a broadcast / multicast (BCMCS) service is processed in the same manner as the paging method performed by the existing 1xEV-DO. (S70).

That is, in the BCMCS system, a hash function is performed with a session seed, which is stored terminal information, or a paging message is assigned to a specific slot in accordance with a standard control channel cycle. Message) is transmitted to the terminal 10.

As described above, according to the method for determining terminal paging in a FA allocated to a mobile communication broadcast service according to the present invention, a paging message processing is performed to deliver packet data to a corresponding terminal in a FA allocated for a broadcast / multicast service (BCMCS). When checking the information of the terminal, by determining whether or not to deliver the paging can minimize the influence of other terminals receiving the broadcast / multicast service (BCMCS) can provide excellent broadcast service quality.
