Background technology
In the mobile communication system, in 3GPP Long Term Evolution (LTE, Long Term Evolution) communication standard, beep-page message is mapped on the Physical Downlink Shared Channel, sends on the resource location of descending shared control signal channel indication.At present, the specific practice of utilizing Physical Downlink Shared Channel to carry out paging is: network side adopts descending shared control signal channel bearing call Indication message, and at this moment, this descending shared control signal channel is called Page Indication Channel.The information that sends on Page Indication Channel comprises: paging indication (PI), the frequency of carrying the Physical Downlink Shared Channel of corresponding paging channel (PCH), time slot configuration information, but do not comprise static configuration informations such as coded system as PCH, modulation system, these static configuration informations are by regulation and stipulation or by system broadcast message notice terminal.Usually, identify Page Indication Channel with specific identification sign (ID), such as: the user ID (UE_ID) of utilizing paging ID to replace in the channel architecture of generic downlink shared control channel identifies Page Indication Channel; Terminal judges by the described specific ID of monitoring whether descending shared control signal channel is Page Indication Channel; After determining to be Page Indication Channel, terminal is determined the paging group under self earlier; Thereby learn the Page Indication Channel that oneself should be monitored; Then, according to discontinuous reception (DRX) cycle of being disposed, periodically the Page Indication Channel under self is received.
Can use different paging ID to distinguish between the above-mentioned Page Indication Channel, also can use different running time-frequency resource positions to distinguish.In the prior art, the channel architecture of Page Indication Channel comprises configuration information of paging ID, paging indication (PI), Physical Downlink Shared Channel or the like as shown in Table 1.

In the prior art scheme, the PI in the paging indicating message adopts the form of bit map (bitmap) to represent whether corresponding paging group is paged: when PI gets 1, represent that corresponding paging group is paged; When PI gets 0, represent that corresponding paging group is not paged.But, be subject to the capacity of descending shared control signal channel, can not carry too many PI in every Page Indication Channel, a general descending shared control signaling can only be carried the PI of dozens of paging group.So, when a plurality of paging group of needs paging simultaneously, may need to take many Page Indication Channels.And in the practical application of system; usually can there be up to a hundred paging groups simultaneously; in some cases; under system message change situation; network needs all terminals of paging to trigger their reading system broadcasts again, just needs to send many paging indicating messages, not only serious waste of resources according to existing paging scheme; and can be because paging indication take too much descending shared control signal channel resource, cause not having descending shared control signal channel can be used for dispatch user data.
Be paging information bearing method in the example explanation prior art with TDD system subframe structure below, Fig. 1 is Page Indication Channel and a paging channel corresponding relation schematic diagram in the prior art, among Fig. 1, TS2 to TS8 is the uplink service time slot, TS0, TS1 and TS9 to TS13 are the downlink business time slot, upper left little square frame is a dispatch in the downlink business time slot, and not having the dispatch of filling pattern is the general control signaling, is used for dispatch user data; Among the downlink business time slot TS9, the dispatch with filling pattern is represented Page Indication Channel, the different different Page Indication Channels of filling pattern representative; The pane that this dispatch back has same filling pattern is the Resource Block that is used for bearing call message that paging indication dispatch is dispatched, i.e. paging channel.
Under the situation of extensive paging, as shown in Figure 1, among the downlink business time slot TS9, network has been initiated paging to a plurality of paging groups, four Page Indication Channels have been used altogether, indicate a Resource Block in the configuration information territory of the Physical Downlink Shared Channel of every Page Indication Channel, be used to carry corresponding beep-page message.Owing to the terminal number of paging among every PCH is distinguished to some extent, so the size of the Resource Block that distributes is also different.Suppose that this downlink business time slot has only four descending shared control signal channels, as can be seen, because paging indication has taken whole descending shared control signal channels, dispatching downlink user data more among the TS9.
Obviously, under existing paging scheme, when network side was initiated extensive paging, paging indicating message need be carried by a large amount of descending shared control signal channels, and resource utilization is low.

Fig. 3 is the realization flow figure of paging indicating message bearing method of the present invention, and as shown in Figure 3, this method may further comprise the steps:
Step 11, base station are provided with main Page Indication Channel and auxilliary Page Indication Channel;
Here, the setting of main and auxiliary Page Indication Channel is by distributing different paging ID or specifying fixing resource location for main and auxiliary Page Indication Channel and realize for different Page Indication Channels.
Step 12, terminal are determined the paging group of the corresponding unique PI under self;
The definite of described paging group can use following scheme: a kind of is to stipulate paging grouping scheme by agreement, and rule of classification is write terminal that terminal is calculated according to rule of classification, can know the paging group that self is affiliated; Another kind is, base station regulation paging grouping scheme, and rule of classification broadcasted in system broadcast message, and terminal is determined paging group under self according to the system broadcast message that receives.
Step 13, paging indication is sent on main and auxiliary Page Indication Channel; The corresponding PCH positional information of all paging indications sends on main Page Indication Channel.
When step 14, the terminal paging group under self is paged, understand PCH, determine whether self is paged according to the PCH positional information on the main Page Indication Channel.
Here, describedly determine whether paged being meant if the discernible unique identification of terminal is arranged on the PCH, for example: the temporary user identifier (TMSI) of certain terminal is arranged on the PCH, and then this terminal check self is paged.
