Abstract
The invention discloses an overload control method and a device of controlling a channel in a wireless communication system, which is used in overload control of a page message. The method includes: step 1), the wireless communication system sends a paging message for paging receiving terminal; step 2), the control channel of the prior cell judges whether total length of the page message joining a forward queue exceeds a maximum message length borne by the prior periodic control channel; if exceeding, judging whether the page message can join the forward queue according to time preference and priority principle; if the page message can join the forward queue, adding the page message into the forward queue and send the page message according to the forward queue. The invention realizes reasonable control and selection of the page message when the page message to be sent by AN on the control channel exceeds the control channel bearing capability, and prevents normal overhead message transmit from being blocked by excessive page messages on AN control channel.
Description
Technical field
The present invention relates to wireless communication system, particularly relate to the overload controlling method and the device thereof of control channel in a kind of wireless communication system.
Background technology
CDMA2000 1X EVDO technology is a branch of CDMA2000 standard series, provides support for the high speed wireless data business specially.Can with the common networking of CDMA2000 1X network that speech business and low-speed data service are provided, use the bandwidth under the different frequent points.Wherein CDMA is (CodeDivision Multiple Access) code division multiple access, and EVDO is (Evolution Data Only/EvolutionData Optimized, the data, services of evolution, optimization).
CDMA2000 1X EVDO forward channel adopts time division way, and all users share the forward direction time slot of this sector in the sector.Wherein control channel is the common signal channel of all users in the sector, the control channel in a sector.Two kinds of important messages of control channel carrying:
1) a kind of is Overhead Message, and accessing terminal, (Access Terminate AT) is known access network (Access Network, basic configuration information AN) by Overhead Message;
2) a kind of is user-dependent service messages such as beep-page message, traffic-channel assignment message.
Overhead Message comprises synchronization message, quick configuration messages, inserts message, sector message, reverse rate restriction of message and broadcast overhead messages, and these Overhead Messages are to go out every certain synchronization control channel cycle timed sending.
User-dependent service messages such as beep-page message, traffic-channel assignment message are that aperiodicity produces, and beep-page message particularly might produce a large amount of beep-page message call access terminal AT at access network AN sometime, has very strong burst feature.It is exactly to send at the listening period of access terminal AT that beep-page message also has characteristics, is responsible for being in the access terminal AT of resting state and can't receives the beep-page message that access network AN sends.
Because beep-page message has above-mentioned feature, sudden when promptly producing, a large amount of property, the periodicity during transmission can produce great impact to systematic function when access network AN experiences this situation.Normal Overhead Message sends if a large amount of beep-page messages blocks the sub-district, can cause the forward signal of this sub-district to lose, and access terminal AT can't connecting system, and systematic function is produced significant impact.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is made further more detailed description.
As shown in Figure 1, be the overload controlling method flow chart of beep-page message of the present invention.In Fig. 1, system carries out selecting based on time sequencing and priority to beep-page message.Carry out caching process for the beep-page message that surpasses current period control channel bearing capacity,, then abandon this beep-page message if the formation in next transmission cycle is still transshipped.
This overload controlling method runs on access network AN, the corresponding algorithm copy of sector control channel, and it is based on time priority principle and priority principle.Specifically, when access network AN produces a large amount of beep-page message, preferentially send the sector Overhead Message, putting before this,, then carry out following processing according to following two principle if control channel also has bearing space.
A1) time priority principle, promptly early to beep-page message preferentially send;
A2) priority principle if several beep-page messages arrive in the scope sometime, then preferentially sends the high beep-page message of priority, and if do not have bearing space, then these beep-page messages are carried out caching process.
Step 101, CDMA 1X EVDO communication system is carried out system initialization;
In this step, the maximum message length that control channel can carry is different because of the rate configuration of control channel.
Step 104 if beep-page message does not transship, is then constructed the transmit queue of beep-page message, after the wait delivery time arrives, according to transmit queue beep-page message is sent to access terminal AT by airlink;
Particularly, the time priority principle is meant for many beep-page messages, and early to beep-page message early sends, and if time range can't be distinguished, then the beep-page message that priority is high preferentially sends;
As shown in Figure 2, be the overloading control device structure chart of beep-page message of the present invention.This device 200 comprises access terminal AT 25, also comprises:
Overload judge module 22, connection message paging module 21 is used for judging by the control channel of current area whether the total length behind the beep-page message adding transmit queue surpasses the maximum message length that the current period control channel can carry;
Wherein, the maximum message length that can carry of control channel is determined according to the rate configuration of control channel.
When the total length after beep-page message adds transmit queue surpassed the maximum message length that the current period control channel can carry, the processing module 23 of transshipping was directly constructed the transmit queue of beep-page message.
When judging that according to time priority principle and priority principle beep-page message can not add transmit queue, 23 pairs of beep-page messages of overload processing module carry out caching process, and the transmit queue that sends the cycle when the next one of control channel abandons this beep-page message when being in full state.
The overload controlling method of the control channel that the present invention proposes also is specially adapted in the wireless telecommunication system of time division way, and all users share the scene of down-chain resource in the group by the forward direction time-derived channel.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
