In order to make those skilled in the art person understand the scheme of the embodiment of the invention better, the embodiment of the invention is done further to specify below in conjunction with accompanying drawing and execution mode.

At the terminal after network side send to insert request; If there is channel to distribute; Network side can send assignment immediately (IMMEDIATE ASSIGNMENT) message (assignation information that only comprises a terminal) or expand assignment immediately (IMMEDIATE ASSIGNMENTEXTENDED) message (assignation information that comprises two terminals simultaneously) to the terminal through CCCH, is used for to the terminal distribution Dedicated Signaling Channel; Can not distribute if there is channel, network side can send assignment refuse information immediately (IMMEDIATE ASSIGNMENT REJECT) to the terminal through CCCH.In addition, for the terminal under the idle condition or as called terminal, network side can send paging (PAGING) message and come triggering terminal to carry out certain territory establishment of connection.

For this reason; The method and apparatus that embodiment of the invention control terminal inserts, network side carries corresponding indication information in above-mentioned these descending control messages, so that will take place when congested in that network is congested maybe; Make the terminal of some low priorities after waiting for certain hour, initiate at random to insert; Perhaps make the terminal of some low priorities in the certain hour scope, in the time slot scope of radio frames, initiate at random to insert, thereby the access of control terminal effectively reduce access interference.Correspondingly; Embodiment of the invention terminal access method and equipment; Monitor and corresponding all the descending CCCHs of its place paging group before send inserting request message and/or afterwards at the low priority terminal, receives descending control messages; If comprise above-mentioned refusal indication information in the descending control messages that receives; Then can refuse indication information and after waiting for certain hour, initiate at random again to insert, perhaps in the certain hour scope, initiate to insert in the time slot scope in radio frames at random, thereby reduce network congestion effectively, reduce access interference according to this.

As shown in Figure 1, be the flow chart of the method for embodiment of the invention control terminal access, may further comprise the steps:

Step 101, network side are added the refusal indication information in descending control messages, this refusal indication information comprises: the value of refusal timer, and to initiate access in the very first time section of indicating terminal after waiting for above-mentioned refusal timer expiry at random.

Particularly; Congested difference on opportunity takes place according to network side; Add above-mentioned refusal indication information in any one or more descending control messages that network side can be mentioned in front; The value of above-mentioned very first time section can be the value of network side and end side agreement, also can indicate through the information that network side is added in the above-mentioned descending control messages.Such as:

(1) utilize channel type (Channel Type) field in the immediate assignment message to represent above-mentioned refusal indication information, following such as Channel Type is carried out new definition:

00000 low priority terminal wait inserts in very first time section after 10 seconds at random;

00001 low priority terminal wait inserts in very first time section after 15 seconds at random;

00010 low priority terminal wait inserts in very first time section after 20 seconds at random.

......

(2) residue of the assignment immediately in immediate assignment message field (IA Rest Octets); The refusal of assignment immediately residue field (IAR Rest Octets) or idle half field (SpareHalf Octet) in the assignment refuse information immediately; Expansion assignment immediately residue field (IAX Rest Octets) in the expansion immediate assignment message; Add the refusal indication information in paging Class1 residue field (P1 Rest Octets) in the beep-page message or paging type 2 residue fields (P2Rest Octets) or the paging type 3 residue fields (P3 Rest Octets).

Such as in above-mentioned these fields, increasing a new field, be used for representing above-mentioned refusal indication information, this refusal indication information comprises and is used to the parameter of indicating the parameter of the value of refusing timer and being used to indicate the value of very first time section, and is specific as follows:

{

......

{0|1＜Reject?timer?value：bit(2)＞}

{0|1＜Access?time?scope：bit(2)＞}

}

Wherein, parameters R eject timer value can define as follows:

00 low priority terminal wait inserts in very first time section after 10 seconds at random;

01 low priority terminal wait inserts in very first time section after 15 seconds at random;

10 low priority terminal waits insert in very first time section after 20 seconds at random;

11 low priority terminal waits insert in very first time section after 25 seconds at random.

Parameter A ccess time scope can define as follows:

The randomization in 20 seconds scopes of 00 terminal inserts;

The randomization in 30 seconds scopes of 01 terminal inserts;

The randomization in 40 seconds scopes of 10 terminals inserts;

The randomization in 50 seconds scopes of 11 terminals inserts.

Need to prove that just for example, the embodiment of the invention is not done qualification to this for the bit number of above-mentioned parameter and time value, such as, bit number also can be 3 bits or 4 bits.

In addition, above-mentionedly be used for indicating the parameter A ccess time scope of the value of very first time section also can be added on system message, network side is notified to the terminal through the value that broadcast mode should very first time section.

Step 102, network side is handed down to the terminal with above-mentioned descending control messages.

This shows; The method that embodiment of the invention control terminal inserts; Network side carries the refusal indication information in descending control messages, the terminal that has low priority with refusal initiated to insert in certain period, thereby can will take place when congested in that network is congested maybe; The access of control terminal effectively reduces access interference.

In another embodiment of method that control terminal of the present invention inserts; Network side also can further divide into groups to the low priority terminal before the descending control messages of having added the refusal indication information is handed down to the terminal, and optionally refuses one or more groups low priority terminal through said refusal indication information and initiate to insert.

Concrete packet mode can have various ways, such as:

Can be divided into different groups according to the different or signatory grade of the priority at low priority terminal; Perhaps, number divide into groups according to the SIM at terminal, last is that 0 and/or 1 low priority terminating is gone into like the refusal card number; Perhaps divide into groups, select the terminal of the low priority of certain percentage to insert according to the network load situation like network side, as 10% with the mode that produces random number; 20%.....90%, after the terminal receives the refusal indication information, at first between 1 to 100, produce a random number; Judge then whether this random number is in unaccepted scope; The indication information that issues like network be 20% have a low priority terminal wait after 10 seconds at a time between in the scope randomization insert, if the random number that the terminal produces is 18, then this terminal is in being rejected the scope of access; If the random number that the terminal produces is greater than 20, then not in being rejected the scope of access.

Under above-mentioned these situation, above-mentioned refusal indication information also can further comprise: group information.The value of above-mentioned refusal timer is the value of the refusal timer of the starting terminal in the grouping of above-mentioned group of information indication.Certainly, network side also can be taken all factors into consideration above-mentioned various different situations, and packets of information such as relevant terminal grade, grouping are contained in the above-mentioned refusal indication information.

For example, utilize Channel Type in the immediate assignment message to refuse the indication information definition,, can define as follows with refusal on the same group low priority terminal not:

00000 all terminal waits with low priority after 10 seconds in the very first time section randomization insert;

00001 all terminal waits with low priority after 20 seconds in the very first time section randomization insert;

00010 all terminal waits with low priority after 30 seconds in the very first time section randomization insert;

00011 all terminal waits with low priority after 40 seconds in the very first time section randomization insert;

00100 belongs to the randomization access in very first time section after 10 seconds of the terminal wait with low priority of group one;

00101 belongs to the randomization access in very first time section after 20 seconds of the terminal wait with low priority of group one;

00110 belongs to the randomization access in very first time section after 30 seconds of the terminal wait with low priority of group one;

00111 belongs to the randomization access in very first time section after 40 seconds of the terminal wait with low priority of group one;

Again for example, utilize the Channel Type in the immediate assignment message to refuse the indication information definition, the low priority terminal with refusal different SIM card number can define as follows:

00010 have low priority and SIM number position, end be 0 terminal wait after 10 seconds in the very first time section randomization insert;

00011 have low priority and SIM number position, end be 0 terminal wait after 20 seconds in the very first time section randomization insert;

00100 have low priority and SIM number position, end be 1 terminal wait after 10 seconds in the very first time section randomization insert;

00101 have low priority and SIM number position, end be 1 terminal wait after 20 seconds in the very first time section randomization insert;

00110 have low priority and SIM number position, end be 2 terminal wait after 10 seconds in the very first time section randomization insert;

00111 have low priority and SIM number position, end be 2 terminal wait after 20 seconds in the very first time section randomization insert;

10100 have low priority and SIM number position, end be 9 terminal wait after 10 seconds in the very first time section randomization insert;

10100 have low priority and SIM number position, end be 9 terminal wait after 20 seconds in the very first time section randomization insert.

Again for example, utilize the Channel Type in the immediate assignment message to refuse the indication information definition, the low priority terminal so that refusal divides into groups according to the mode that produces random number can be defined as follows:

00,010 10% has the randomization access in very first time section after 10 seconds of low priority terminal wait;

00,011 10% has terminal wait randomization access in very first time section after 20 seconds of low priority;

00,100 20% has terminal wait randomization access in very first time section after 10 seconds of low priority;

00,101 20% has terminal wait randomization access in very first time section after 20 seconds of low priority;

00,110 30% has terminal wait randomization access in very first time section after 10 seconds of low priority;

00,111 30% has terminal wait randomization access in very first time section after 20 seconds of low priority;

......

10,000 90% have terminal wait randomization access in very first time section after 10 seconds of low priority;

10,000 90% have terminal wait randomization access in very first time section after 20 seconds of low priority.

Equally; Network side also can be added on the refusal indication information at the low priority terminal of above-mentioned various grouping situation in the specific fields in following one or more descending control messages, and this specific fields can be: IAX Rest Octets field, the P1Rest Octets field in the beep-page message or P2Rest Octets field or P3Rest Octets field in the IA Rest Octets field in the immediate assignment message, the IAR Rest Octets field in the assignment refuse information immediately or Spare Half Octet field, the expansion immediate assignment message.

In addition, also can the information of above-mentioned very first time section be added in above-mentioned these specific fields.

Comprise the parameter of the value that is used to indicate the refusal timer and be used to indicate the parameter of the value of very first time section such as, above-mentioned refusal indication information, specific as follows:

{

......

{0|1＜Reject?timer?value：bit(5)＞}

{0|1＜Access?time?scope：bit(2)＞}

}

For example, above-mentionedly be used to indicate the parameters R eject timer value of the value of refusal timer can define as follows:

......

11100 belong to the randomization access in very first time section after 10 seconds of the terminal wait with low priority of group seven;

11101 belong to the randomization access in very first time section after 20 seconds of the terminal wait with low priority of group seven;

11110 belong to the randomization access in very first time section after 30 seconds of the terminal wait with low priority of group seven;

11111 belong to the randomization access in very first time section after 40 seconds of the terminal wait with low priority of group seven.

Again for example, above-mentioned parameter Reject timer value can define as follows during the low priority terminal of refusal different SIM card number:

......

Above-mentioned parameter Rejecttimer value can define as follows when more for example, refusal utilized the mode of generation random number to refuse the low priority terminal:

......

Parameter A ccess time scope can define as follows:

00 have a low priority terminal randomization in 20 seconds scopes insert;

01 have a low priority terminal randomization in 30 seconds scopes insert;

10 have a low priority terminal randomization in 40 seconds scopes insert;

11 have a low priority terminal randomization in 50 seconds scopes insert.

Need to prove that just for example, the embodiment of the invention is not done qualification to this for the bit number of above-mentioned parameter and time value, such as, also can be 3 bits or 4 bits.

In addition, network side also can be used for indicating the parameter A ccess timescope of the value of very first time section to be added on system message with above-mentioned, and value that should very first time section by broadcast mode is notified to the terminal that needs refusal to insert.

The low priority terminal that more for example, can utilize AC in the existing standard (Access Control, access control) mode to refuse not on the same group initiates to insert; Concrete mode is: the terminal is divided into different classes, and network side can be refused the terminal of a certain class or multiclass simultaneously and initiate to insert, and for example the terminal is divided into different 10 types; Bitmap incoming letter with 10; One type of each expression representes that this Terminal Type is rejected when certain position is 1, such as:

The 0000001001 expression first kind and the 4th type of low priority terminal are rejected access;

Second type of low priority terminal of 0000000010 expression is rejected access;

Class under the terminal is found is rejected when initiating the access request, starts the refusal timer according to the value that issues the refusal timer in the message, in certain section time range, initiates at random behind the wait refusal timer expiry to insert.

Specifically be embodied as the refusal indication information that network side refuses the low priority terminal with the above-mentioned AC of utilization mode and be added in the specific fields in following one or more descending control messages, this specific fields can be: the IAX Rest Octets field in the IA Rest Octets field in the immediate assignment message, the IAR RestOctets field in the assignment refuse information immediately or Spare Half Octet field, the expansion immediate assignment message, P1Rest Octets field or P2Rest Octets field or the P3RestOctets field in the beep-page message.

Above-mentioned refusal indication information comprises the parameter of the value that is used to indicate the refusal timer and is used to indicate the parameter of the value of very first time section, and is specific as follows:

{

......

{0|1＜Access?Control?Class：bit(10)＞}

{0|1＜Reject?timer?value：bit(2)＞}

{0|1＜Access?time?scope：bit(2)＞}

}

Parameter A ccess Control Class is used for representing that which kind of or which type terminal is rejected;

Parameters R eject timer value can define as follows:

The value of 00 timer is 10 seconds;

The value of 01 timer is 20 seconds;

The value of 10 timers is 30 seconds;

The value of 11 timers is 40 seconds;
