Specific embodiment

During the concurrent access network of substantial amounts of MTC terminal, network congestion is easily caused.Network side considers MTC The priority and time delay tolerance of terminal traffic, may temporarily refuse the access of MTC terminal.Work as MTC When terminal is denied access cell, can wait default a period of time (in R10 be 1~1000s) it Attempt access in same cell again afterwards.However, because the MTC terminal number for concurrently accessing is more, quilt The number for refusing the MTC terminal of access is also more.When multiple MTC terminals are accessed again again, can deposit In situation about being denied access again, cause MTC terminal be successfully accessed to network duration it is more long.

In embodiments of the present invention, when the RRC connection refused messages that network side is issued are received, i.e. quilt When network side refusal is accessed, attempted carrying out cell according to the Neighboring Cell List carried in RRC connection refused messages It is resident, rather than resident first service cell is continued to attempt to after waiting a period of time, such that it is able to make MTC terminal being capable of rapidly access network.

It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to Accompanying drawing is described in detail to specific embodiment of the invention.

The embodiment of the invention provides a kind of MTC terminal access control method, reference picture 1, below It is described in detail by specific steps.

Step S101, judges whether that initiating RRC connections to network side sets up request.

In specific implementation, when MTC terminal is present carries out the demand of business transmission with network side, can be with Wireless heterogeneous networks (Radio Resource Control, RRC) connection is initiated to network side set up request, To ask to be linked into Serving cell.

In embodiments of the present invention, when MTC terminal initiates RRC connection foundation requests to network side, the phase Hope and set up network connection with first service cell.

After RRC connection foundation requests are initiated to network side, before not yet completion RRC connections are set up, When i.e. MTC terminal is waiting the RRC connection establishment response message that network side is issued, step can be performed Rapid S102;Receiving the RRC connection establishment response message that network side is issued, or not to network side When initiating RRC connection foundation requests, can be with end operation flow.

Step S102, judges whether to receive the RRC connection refused messages that the network side is issued.

In specific implementation, network side can be according to the current load condition of first service cell or MTC The factors such as the service priority of terminal come judge whether refusal MTC terminal first service cell access. When network side refusal MTC terminal is linked into first service cell, RRC can be issued to MTC terminal Connection refused message.

For example, when network side detect the current load value of first service cell it is higher when, due to MTC ends It is relatively low that end service priority is generally set, to ensure that first service cell is provided normally for non-MTC terminal Business, then can first refuse MTC terminal and be linked into first service cell.

MTC terminal can perform step after the RRC connection refused messages that network side is issued are received S103;Otherwise, end operation flow.

Step S103, obtains the Neighboring Cell List for supporting MTC communication from the RRC connection refused messages.

In embodiments of the present invention, in RRC connection refused messages, support MTC can be carried and is led to The Neighboring Cell List of letter, can include the adjacent cell of one or more first service cells in Neighboring Cell List.

In embodiments of the present invention, after network side determines that refusal MTC terminal is accessed, can be in RRC Frequency and the support that MTC communication is supported around first service cell are carried in connection refused message Cell list on the frequency of MTC communication, namely first service cell Neighboring Cell List.

After Neighboring Cell List is got, Neighboring Cell List can be preserved, and perform step S104.

Step S104, attempts accessing the cell in the Neighboring Cell List.

In specific implementation, after the Neighboring Cell List carried in getting RRC connection refused messages, you can Attempt accessing to the cell in Neighboring Cell List successively.

In embodiments of the present invention, the cell in Neighboring Cell List can be provided with corresponding priority.Then MTC Terminal, can be according to the height of priority orders in the cell in attempting accessing Neighboring Cell List, preferential choosing The cell for selecting high priority carries out trial access.When attempting being successfully accessed in the cell of limit priority, Need not then continue to attempt to access other cells in Neighboring Cell List.When the cell in limit priority is attempted connecing When entering unsuccessfully, then can attempt accessing in the cell of secondary one-level priority.By that analogy, until MTC ends End is successfully accessed some cell into Neighboring Cell List.

The priority of the cell in Neighboring Cell List can be set in advance by network side.Implement in the present invention In example, the current loads value of the cell that network side can be in Neighboring Cell List is corresponding to set each cell Priority.The corresponding priority of each cell can be with its current loads value inverse correlation, the implication of inverse correlation For:The current loads value of cell is bigger, then its priority level initializing is lower;Conversely, cell is current negative Charge values are smaller, then its priority level initializing is higher.

Native region priority is set according to cell load value to be advantageous in that:In Neighboring Cell List, it is understood that there may be when The larger cell of preload value, in this case, if the larger cell of current loads value is set into height The cell of priority, then when there is multiple MTC terminals accesses, still suffer from being denied access possibility.Cause This, high priority is set to by by the relatively low cell of load value, it is possible to reduce MTC terminal is because cell The possibility that load value is higher and is denied access.

In embodiments of the present invention, in the cell in attempting accessing Neighboring Cell List, it is understood that there may be MTC ends The end scene that all of cell cannot be accessed in the neighbor list.RRC connection refusals are there is likely to be to disappear The scene of Neighboring Cell List is not carried in breath, now, MTC terminal cannot disappear from RRC connection refusals Neighboring Cell List is obtained in breath.

For above two scene, can only according to currently existing scheme, after certain preset duration is waited, Again RRC connections are initiated to network side and sets up request, to access first service cell.Wherein, when presetting Length can refer to initiate the duration that request is set up in connection again after refusal is connected specified in existing scheme, In LTE R8 standards, preset duration is 1~16s;In LTE R10 standards, preset duration is 1~1800s.

In existing scheme, when MTC terminal is denied access first service cell, MTC terminal meeting After waiting a period of time, access first service cell is reattempted to.However, as the MTC being rejected Terminal is more, and when initiating access request simultaneously, may still suffer from situation about being denied access.Work as MTC When terminal is repeatedly continuously refused to access, MTC terminal may cannot access to network for a long time.

And in embodiments of the present invention, when the RRC connection refused messages that network side is issued are received, i.e., When refusing to access by network side, carried out according to the Neighboring Cell List trial carried in RRC connection refused messages small Area is resident, rather than continuing to attempt to resident first service cell after waiting a period of time, such that it is able to Enable MTC terminal rapidly access network.

In specific implementation, before step S201 is performed, can also first judge that current first service is small Whether MTC communication is supported in area.When first service cell supports MTC communication, step S201 is just performed; Otherwise, the operation in the embodiment of the present invention is not performed.

When request is set up in the RRC connections for receiving MTC terminal initiation, step S202 can be performed; Conversely, when request is set up in the RRC connections for not receiving MTC terminal initiation, step can be repeated Rapid S201.

Step S202, judges whether to refuse the access of the MTC terminal.

In embodiments of the present invention, when network side is known the load value of first service cell is larger when, or When the grade of service of current MTC terminal is relatively low, for preferably for non-MTC terminal provides service, can be with Refuse the access of MTC terminal.

When the access of MTC terminal is refused, step S203 is performed;When the access of MTC terminal is allowed, Then service connection directly can be set up with MTC terminal, so that end operation flow.

Step S203, generates Neighboring Cell List.

The neighbour of the first service cell for supporting MTC communication can be included in specific implementation, in Neighboring Cell List Cell.

In embodiments of the present invention, network side can first obtain first service small when Neighboring Cell List is generated The load value of the adjacent cell of the corresponding all support MTC communications in area, afterwards by all support MTC communications Adjacent cell load value be compared with a preset value successively, by load value less than preset value adjacent cell It is added in Neighboring Cell List, so as to generate Neighboring Cell List.

In the neighbor list, the corresponding precedence information of each cell can also be included.Network side can basis The current loads value of the cell in Neighboring Cell List sets the corresponding priority of each cell.Cell it is current Load value is bigger, then its priority level initializing is lower;Conversely, the current loads value of cell is smaller, then its Priority level initializing it is higher.

After Neighboring Cell List is generated, step S204 is performed.

Step S204, RRC connection refused messages are sent to the MTC terminal.

In specific implementation, step can be included in the RRC connection refused messages to MTC terminal transmission The Neighboring Cell List generated in S203.After MTC terminal receives Neighboring Cell List, can attempt accessing neighbour Cell in area's list.
