Accessing terminal from from the TD_Zone_IE () or MBS_Zone_IE () of the DL-MAP message received by system of receiving broadcast service detects MBS realm identifier, and by detected new MBS realm identifier compared with its old MBS realm identifier.If the new MBS realm identifier received is different from old MBS realm identifier, then access terminal send about multicast ip address, port numbers, key, CID and such as broadcast relevant information and so on request to access point, recognize it and entered a new MBS region.Subsequently, access terminal from access point and receive the relevant information of broadcast, and continue to receive broadcast.
Fig. 7 illustrates according to the first embodiment of the present invention, for changing the message flow diagram of the process in MBS region.With reference to Fig. 7, in step 102, if need to receive broadcast, then access terminal the relevant information obtained from the cell-of-origin of MBS realm identifier=1 about broadcast program.At this, the relevant information about broadcast program can comprise the list of broadcast in service or available service.In step 104, by Dynamic Service Addition Request (DSA-REQ), access terminal send about picture for from cell-of-origin reception about the request of the information the CID of the data (image, speech, text, etc.) of broadcast program and key to access point or base station.In this moment, accessing terminal transfers to access point together by the multicast ip address about respective program.In step 106, dynamic service-the x of the validity of access point transmission instruction request receives (DSX-RVD) to accessing terminal, and then in step 108, transmission dynamic service increases response (DSA-RSP) (response of the supportable of instruction QoS) to accessing terminal.DSA-RSP comprises the information as the CID for receiving broadcast from cell-of-origin and key.Then, in step 110, response DSA-RSP, this terminal transmission dynamic service increases confirmation (DSA-ACK) to access point, and uses this receives information to broadcast in step 112.That is, access terminal from the DL-MAP source codec received by cell-of-origin, and start to receive the physical channel of the CID having desired program.Access terminal and store included by DL-MAP message, the MBS zone identifier value of cell-of-origin, that is, " 1 ".
If accessed terminal in step 114 move to Target cell, then this accesses terminal from Target cell and receives DL-MAP message, and in step 116, by analyzing TD_Zone_IE or MBS_Zone_IE of DL-MAP message, detect the MBS realm identifier " 2 " of Target cell.Because the MBS realm identifier " 2 " of Target cell is different from MBS realm identifier " 1 " previously stored therein, so, in step 118, if needed, access terminal the request of transmission for the relevant information of the reception of new broadcast program to Target cell, determines that it can not receive current broadcast continuously.If needed, access terminal and change Alertness into, it can transmit the request of the information of being correlated with about new broadcast program reception wherein.Thereafter, in step 120, in order to inquire whether its broadcast just received in cell-of-origin is available in Target cell, the transmission DSA-REQ message that accesses terminal is to Target cell.After step 122 receives DSX_RVD from Target cell, and then to receive the DSA_RSP comprising the information that new broadcast reception is correlated with from Target cell in step 124 after, in step 126, response DSX_RVD and DSA_RSP, access terminal transmission DSA_ACK, and in step 128 from Target cell receiving broadcast service.Then access terminal store M BS realm identifier " 2 ".The broadcast just received in cell-of-origin if accessed terminal is disabled in Target cell, then access terminal and obtain the list of available programs from Target cell, and start the reception of new broadcast program.
Fig. 8 illustrates according to the first embodiment of the present invention, the flow chart of the operation accessed terminal.With reference to Fig. 8, in step 200, access terminal from the access point of cell-of-origin and obtain programme information, and in step 202, obtain physic channel information (CID and key) corresponding to user-selected broadcast program and MBS realm identifier from access point or base station.In step 204, access terminal the MBS realm identifier stored about its current region, and in step 206, use this physic channel information from cell-of-origin receiving broadcast service.
In step 208, if receive DL-MAP message from the access point of Target cell, then in step 210, access terminal and determine whether MBS realm identifier included in received DL-MAP message equals MBS realm identifier stored therein.If MBS realm identifier is equal to each other, then accessing terminal turns back to step 206, with receiving broadcast service continuously.But, if MBS realm identifier is unequal each other, then accesses terminal and proceed to the step 212 that it stores received MBS realm identifier again.In step 214, access terminal and notify his/her leaving from the old MBS region corresponding to old broadcast program of user.This leave message can be provided to user by liquid crystal display (LCD) panel, loud speaker or vibrator.In step 216, access terminal and attempt being used in the physic channel information just used in cell-of-origin, and receive broadcast program in Target cell.The process of step 216 is selectable.That is, even if when about identical broadcasting service, during cell change, also transmit in the same way in the system of broadcast program, the process of step 216 is performed.Otherwise, the process of step 216 can be skipped.At this, suppose the process performing step 216.
After the failure of reception broadcast program, in step 218, the request of the physic channel information of the broadcast program that the transmission that accesses terminal receives from cell-of-origin just continuously about it is to the access point of Target cell.In step 220, the request of response physic channel information, accesses terminal and determines whether to receive the instruction information of the availability of broadcast program and the physic channel information about this broadcast program Target cell from Target cell.If received this information, then access terminal and turned back to included by its use in the response message, about the physic channel information of this broadcast program, received the step 206 of broadcast program continuously.
But, if also do not receive the instruction information of the availability of broadcast program and the physic channel information about this broadcast program in Target cell, then in step 222, access terminal and inquire user whether he/her will receive new broadcast program.Can be done this by show text message or icon on the lcd panel to inquire about.If user expects to receive new broadcast program, if that is, input is about the request signal of new broadcasting service, then the request of transmission about the required information about broadcast program that access terminal is to the access point of Target cell.After this, accessing terminal and turn back to step 200, with the information by obtaining the new broadcast program selected by associated subscriber, receiving new broadcast program from Target cell.If user undesirably receives new broadcast program, then in step 224, access terminal and stop old broadcast program.

Second embodiment of the present invention CID identifies MBS region.The broadcast program transmitted from an access point has himself unique CID.Therefore, the community that the second embodiment has the program of identical CID with transmission forms a MBS region.Thus, the community of transmitting multiple program has multiple MBS realm identifier.
Fig. 9 illustrates according to a second embodiment of the present invention, has the diagram of the configuration of the community of multiple MBS realm identifier.As illustrated in, there are 3 MBS regions A, B, C.This MBS area transmissions has the program of the different CID of CID# 1, CID#2 and CID#3, and comprises 4 communities.Community # 1 belongs to 2 MBS region A and C, because its transmission has the program of CID# 1 and CID#3.Community #4 only belongs to a MBS region C, because it only transmits the program with CID#3.
Each of community passes through the MBS zone identifier list of at least one that DL-MAP transmission of messages indicates the MBS region of himself.Community each in access terminal and obtain MBS zone identifier list by analyzing this DL-MAP message.MBS zone identifier list is included in TD_Zone_IE or MBS_Zone_IE by DL-MAP message.
Figure 10 illustrates according to a second embodiment of the present invention, comprises the diagram of the form of message of the situation of MBS zone identifier list about the TD_Zone_IE in DL-MAP message.As illustrated in, TD_Zone_IE comprises 4 Bits Expanding DIUC, 4 bit length territories, the N_MBS_Zone_identifier of number of 8 instruction MBS realm identifiers and the MBS realm identifier for identifying current region.Expansion DIUC represents the DIUC of TD_Zone_IE.
Figure 11 illustrates according to a second embodiment of the present invention, comprises the diagram of the form of message of the situation of MBS zone identifier list about the MBS_Zone_IE in DL-MAP message.As illustrated in, MBS_Zone_IE comprises 4 Bits Expanding DIUC, 4 bit length territories and multiple MBS realm identifier.The number of MBS realm identifier can be determined by length field.Expansion DIUC represents the DIUC of MBS_Zone_IE.
Accessing terminal from from the TD_Zone_IE () or MBS_Zone_IE () of the DL-MAP message received by this system of receiving broadcast service detects MBS zone identifier list, and by compared with MBS realm identifier old to detected MBS zone identifier list and its.If do not comprise old MBS realm identifier in this MBS zone identifier list, then access terminal and can send request about multicast ip address, port numbers, key, CID and such as relevant information of broadcast and so on to access point, recognize it and entered a new MBS region.Subsequently, access terminal from access point and receive the relevant information of broadcast, and continue to receive broadcast.
As described above, access point uses the current community of DL-MAP message identification to belong to which MBS.By DSA-RSP message instead of DL-MAP transmission of messages about the Mapping information in MBS region being mapped to CID.If accessed terminal, transmission is for asking the DSA-REQ message of desired broadcast program to access point, then respond DSA-REQ message, access point uses DSA-RSP message, and the Mapping information in the CID providing asked broadcast program and the MBS region being mapped to this CID is to accessing terminal.MBS zone identifier information in DSA-RSP message configures as illustrated in table 1.
Table 1
| Type | Length | Value | Scope |
| [145/146].29 | 8 | MBS realm identifier | DSA-RSP |
Access terminal its MBS zone identifier list MY_ZONE_ID_LIST of self registered wherein of management, and total MBS zone identifier list ZONE_ID_LIST.MY_ZONE_ID_LIST comprises at least one MBS realm identifier corresponding to the current CID just received that accesses terminal.ZONE_ID_LIST comprises all MBS realm identifiers belonging to current community, that is, all MBS realm identifiers obtained from DL-MAP message.Hereafter the management of list will described.
First, the situation in the MBS region left accessing terminal belonging to it is described.From the MBS zone identifier list received by new community, not comprising the MBS realm identifier of the CID just received corresponding to accessing terminal, accessing terminal and detecting its old MBS realm identifier from MY_ZONE_ID_LIST and ZONE_ID_LIST.In this situation, the access point of the transmission DSA-REQ message that accesses terminal to new community, and then determine whether the broadcast program being received the CID just received corresponding to it by another physical channel.If have received this broadcast program by another physical channel, then then the corresponding MBS realm identifier of this new community of increase that accesses terminal to MY_ZONE_ID_LIST, and receives this broadcast program continuously.But, if do not transmit this broadcast program, then access terminal from the access point of new community and receive the relevant information of broadcast program, and notify that user can use new program.
Secondly, the situation that the MBS zone identifier list by the MBS region leaving himself to accessing terminal but received by the access point from new community comprises MY_ZONE_ID_LIST describes.Namely, the MBS region of the current received program of transmission is left if accessed terminal, but current received program equals the program of broadcasting from Target cell, then access terminal from Target cell and receive ZONE_ID_LIST, and received ZONE_ID_LIST is updated to MBS zone identifier list, and receive its old broadcast just received continuously.Access terminal and can transmit DSA-REQ message or another request message, to obtain and broadcast related out of Memory.
When entering a new MBS region when accessing terminal, under user request, this accesses terminal and accesses the access point of new community, and receives the information relevant with the broadcast program provided in corresponding MBS region, and according to this broadcast program information, notify user's available broadcast programs.If user expects to receive this broadcast program, then access terminal and start to receive new broadcast program.
Aforementioned description is done with reference to Fig. 9.Access terminal in 12 Zheng community #2 and receive broadcast with CID#3.In the #2 of community, accessing terminal 12 belongs to MBS region C, and the DL-MAP message of community #2 comprises MBS zone identifier list { A, C}.If accessed terminal, 12 move to community #3, then this access terminal 12 in the #3 of community receive comprise MBS zone identifier list { the DL-MAP message of B, C}.In this situation, because community #3 also belongs to MBS region C, access terminal 12 continuously with CID#3 reception broadcast, and do not transmit the request of the information of being correlated with about new broadcast.Under user request, the request of the information that 12 transmission that access terminal are correlated with about broadcast program to the community #3 in the C of MBS region, and is attempted receiving new broadcast program.
As another example, suppose that receiving accessing terminal of broadcast with CID# 1 in the #2 of Zheng community 12 moves to community #3.In this situation, { B, C}, recognize it and can not receive broadcast with CID# 1 in #3 of Zai community, and stop receiving broadcast with CID# 1 by analyzing the MBS zone identifier list of community #3 to access terminal 12.In another situation, in order to determine whether it can receive its old broadcast program with another CID continuously, the access point of the 12 transmission DSA-REQ message that access terminal to community #3.The result of the DSA-RSP message received as analyzing responding DSA-REQ message, if determine the broadcast program that community #3 is just providing old, then access terminal its MY_ZONE_ID_LIST of 12 renewals, and receive broadcast program from community #3 continuously.But if community #3 does not provide this broadcast program, then in order to obtain available new broadcast program, under user request, the request of the information that 12 transmission that access terminal are correlated with about broadcast program is to the access point of community #3.
Another example, supposes that just in the community #4 of MBS region C, receiving accessing terminal of broadcast with CID#3 14 moves to community #2 in the A of MBS region.In this situation, 14 move to new MBS region A because access terminal, it sends request about the relevant information for receiving broadcast program to community #2.If user expects to do like this, then accessing terminal 14 receives its old broadcast program with CID#3 continuously.
Figure 12 A to 12C illustrates according to a second embodiment of the present invention, the flow chart of the MBS zone change operation accessed terminal.
With reference to Figure 12 A, in step 302, access terminal from the access point of cell-of-origin or base station and obtain broadcast program information, and in step 304, on the basis of request, obtain corresponding to the physic channel information (CID and key) of user-selected broadcast program and MBS realm identifier from access point.In step 306, accessing terminal is increased to this MBS realm identifier in its MY_ZONE_ID_LIST, and in step 308, uses this physic channel information to receive broadcast.The ZONE_ID_LIST accessed terminal comprises the MBS realm identifier in all MBS regions be mapped to belonging to cell-of-origin.
When to move to contiguous Target cell from cell-of-origin when accessing terminal, if in step 310, DL-MAP message is received from the access point of Target cell, then in step 312, access terminal and determine whether MBS zone identifier list included in received DL-MAP message equals ZONE_ID_LIST.If they are equal to each other, then access terminal and turn back to step 308, to receive broadcast continuously.But, if they are unequal each other, then access terminal and proceed to step 314, to determine that it has entered a new MBS region, still only have left old MBS region.
In step 314, access terminal and determine whether comprise MY_ZONE_ID_LIST in received MBS zone identifier list.If do not comprise MY_ZONE_ID_LIST in received MBS zone identifier list, then accessing terminal proceeds to the step 332 of Figure 12 B, determines that it have left the MBS region corresponding to its old broadcast program.
With reference to Figure 12 B, in step 332, access terminal and ZONE_ID_LIST is updated to received MBS zone identifier list, and in step 334, notify user's leaving from old MBS region, selectively, can between following step 336 and 340, or between following step 344 and 346, perform the process of step 334.In step 336, access terminal and attempt being used in the old physic channel information used in cell-of-origin, receive broadcast program from Target cell, and determine whether it successfully receives broadcast program from Target cell.If accessed terminal successfully receive broadcast program from Target cell, then accessing terminal turns back to step 308, to receive broadcast program continuously.But fail to receive broadcast program if accessed terminal, then accessing terminal proceeds to step 340.
In step 340, access terminal from MY_ZONE_ID_LIST, delete the MBS realm identifier in the MBS region corresponding to unavailable physical channel, and in step 342, transmit about being used for the request of the physic channel information receiving old broadcast program to the access point of Target cell.In step 344, access terminal and determine whether that response request have received the information of the availability of the old broadcast program of instruction from the access point of Target cell.If in Target cell, old broadcast program is available, then receive the physic channel information for receiving old broadcast program together from Target cell.If in Target cell, broadcast program is available, then accessing terminal turns back to step 308, to use this physic channel information, receives old broadcast program continuously from Target cell.
In step 344, if determine that broadcast program old in Target cell is disabled, then in step 346, access terminal and inquire user whether he/her will receive new broadcast program.If user expects to receive new broadcast program, then access terminal and turn back to step 302, obtain broadcast program information and physic channel information with the access point from Target cell, and receive new broadcast program.Otherwise, in step 348, access terminal and stop old broadcast program.
But, in step 314, if determine to comprise MY_ZONE_ID_LIST in received MBS zone identifier list, then access terminal and proceed to step 316, determine that it does not also leave its old belonging MBS zone, but exist and access terminal and will enter new MBS region or leave the possibility in its old non-belonging MBS region.At this, term " old belonging MBS zone " refers to the MBS region of the broadcast program just received corresponding to accessing terminal, and term " old non-belonging MBS region " refers to not receive corresponding to accessing terminal, but the MBS region of the broadcast program that can provide in cell-of-origin.
In step 316, access terminal and determine, except ZONE_ID_LIST, whether received MBS zone identifier list comprises a MBS realm identifier further.If except ZONE_ID_LIST, received MBS zone identifier list comprises a MBS realm identifier further, then in step 320, accessing terminal to arrange indicates the EnterZone entering new MBS region to be yes.Otherwise in step 318, it is no for accessing terminal and arranging EnterZone.In memory included in an access terminal, EnterZone can be realized as a mark.In step 322, access terminal and determine, except received MBS zone identifier list, whether ZONE_ID_LIST comprises a MBS realm identifier further.If except received MBS zone identifier list, ZONE_ID_LIST comprises a MBS realm identifier further, then in step 326, it is no for accessing terminal and arranging instruction from the ExitZone left in its old non-belonging MBS region.Otherwise in step 324, it is yes for accessing terminal and arranging this ExitZone.Equally, can access terminal in included memory using ExitZone as one mark and realize.EnterZone and ExitZone is determined in step 12C.
In the step 328 of Figure 12 C, if EnterZone and ExitZone both, then accessing terminal proceeds to step 350, determines that it leaves its old non-belonging MBS region, and enters new MBS region.But in step 330, if EnterZone is for being and ExitZone is no, then accessing terminal proceeds to step 364, determines that it enters new MBS region.In other situation, access terminal and proceed to step 358, determine that it does not also enter new MBS region, but have left its old non-belonging MBS region.
