Embodiment
One of method purpose of call terminal proposed by the invention is to make paging Fang Buxu send beacon always, can the paging target terminal.For this reason, method of the present invention may further comprise the steps: at first, network sends a paging unit 10, and with reference to shown in Figure 1, the duration of paging unit is T0.Comprise many sync beacon of being convenient to detect in the paging unit, and comprised paging data.In end side, understand to collect paging, wherein T＜T0 less than time interval T.The method of receiving paging comprises: search sync beacon, if search sync beacon, then terminal can utilize sync beacon to carry out synchronously, and paging data is collected in the position of just arranging in paging unit then.
Because T＜T0, therefore in the paging unit time-continuing process, the terminal paging of always having an opportunity to collect.It should be noted that the present invention does not limit the form of beacon and paging data, can use any form that can achieve the goal; The present invention does not limit the aligning method of beacon and paging data yet, can be designed voluntarily by the user; In addition, the present invention does not limit paging duration T 0 and receipts paging interval T yet, and can be set as required by the user.
Exemplify concrete wireless communication system and frame structure below and describe method in the paging of the present invention.
Fig. 2 is the paging unit structure chart according to one embodiment of the present of invention.As an example, present embodiment for example is to be used for gsm communication system, and paging unit is made up of the GSM frame.Wherein, F represents GSM Frequency Correction Burst (GSM frequency correction burst), S represents GSM Synchronize Burst (GSM synchronization burst), and P represents GSM Normal Burst (GSM normal burst), and I represents Idle Frame (idle frame).S is sync beacon, and P is a Frame.In addition, the time of each frame is 120/26ms.
If M=19, so the paging unit duration in this example:
T0＝19＊26＊(120/26)ms＝2280ms。
Beacon in this example is the S frame, comprises FN (Frame Number, frame number) in its data, the FN=1 in first S frame of each paging unit.
Receiving paging interval T in this example should be less than T0, and those skilled in the art as can be known, and the setting of T should guarantee that also terminal can receive paging data piece P0～P3 all in the M-1 subelement.For this reason, T for example is less than 18*26* (120/26)=2160ms.For instance, T=2118ms, the every 2118ms of standby terminal collects paging unit once, if find beacon S, decoding obtains the frame number FN of S frame, carry out synchronously after, terminal can be in 468,469 of agreement, 470,471 frames are collected paging data piece P0,474,475,476,477 frames are collected paging data piece P1,481,482,483,484 frames are collected paging data piece P2,487,488,489,490 frames are collected paging data piece P3.
The paging unit structure chart of Fig. 3 an alternative embodiment of the invention.As an example, present embodiment is to be used for the TD-SCDMA communication system, and paging unit all is made up of the TD-SCDMA burst structure.In the embodiment shown in fig. 3, paging unit 30 comprises a plurality of subelements, and each subelement comprises the DwPTS (descending pilot frequency time slot) as sync beacon, and comprises paging data separately.
Specifically, paging unit is made up of M multi-frame, and each multi-frame comprises a plurality of subframes (shown in the figure 4), duration 5ms as i multi-frame.
In each subframe, TS0-TS6 represents 7 time slots, all adopts the system burst structure among the TD-SCDMA, its structure as shown in Figure 4, length 864chips; DwPTS represents descending pilot frequency time slot, adopts the DwPTS burst structure among the TDS-CDMA, its structure as shown in Figure 5, length 96chips; GP represents free time, length 256chips in addition.
If M=100, then paging unit duration:
T0＝100＊4＊5ms＝2000ms。
Sync beacon DwPTS in this example sends between paging periods always, and the used SYNC_DL of the DwPTS in subframe # 4i～#4i+3 is respectively 4 different SYNC_DL, is designated as SYNC_DL_A, SYNC_DL_B, SYNC_DL_C, SYNC_DL_D.In addition, TS0 sends between paging periods always, the TS1-TS6 free time, has comprised paging data piece and multiple frame number in the entrained data of 4 TS0 of subframe # 4i-#4i+3.Wherein the paging data piece of each subframe # 4i-#4i+3 is formed complete paging data jointly.
Receiving paging interval T in this example should be less than T0, and those skilled in the art as can be known, and the setting of T should guarantee that also terminal can receive paging data pieces all in the M-1 subelement.For this reason, T for example is less than 99*4*5=1980ms.T in this example is 1900ms.
In paging, the every 1900ms of standby terminal collects paging, if search DwPTS, then continue to collect DwPTS, up to it is SYNC_DL_D, be next multi-frame (establishing multiple frame number is i) then as can be known afterwards, collect 4 data that TS0 is entrained of its subframe # 4i-#4i+3, obtain paging data.
In addition, as a kind of conversion to the foregoing description, in the M of the paging unit of another embodiment of the present invention subelement (being multi-frame), have only multiple frame number i in the entrained data of 4 TS0 of the subframe # 4i of 0～(M-2) individual subelement～#4i+3 and do not have paging data, and (M-1) in the individual multi-frame, multiple frame number i and paging data piece have been comprised in the entrained data of 4 TS0 of subframe # 4i-#4i+3.
Receiving paging interval T in this example also should be less than T0, and those skilled in the art as can be known, and the setting of T should guarantee that also terminal can receive the multiple frame number i in the M-2 subelement at the latest, and can receive paging data pieces all in the M-1 subelement.For this reason, T for example is less than 98*4*5=1960ms.T in this example is 1900ms.
In paging, the for example every 1900ms of standby terminal collects paging, if search DwPTS, then continuing to collect DwPTS, is SYNC_DL_D up to it, is next multi-frame (establishing multiple frame number is i) then as can be known afterwards, collect 4 data that TS0 is entrained of its subframe # 4i-#4i+3, obtain multiple frame number i, just (behind (M-1)-i) * 20ms, can receive the paging data piece as can be known.
By the foregoing description as seen, by paging method described in the invention, paging side does not need to send beacon always and gets final product the paging target terminal, so the present invention can save the resource cost of wireless communication system, the raising communication efficiency.
