Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
Consult Fig. 1 for introducing the network topology schematic diagram of relaying in the cell mobile communication systems, the a plurality of sub-districts of control are responsible in base station 1, the relaying 4 that is provided with in the cellular system can the Extended Cell edges cover, be positioned at 3 middle on relaying of sub-district and can increase capacity, and relaying 2 can solve the communication of shadow region, therefore the introducing of relaying can obtain the capacity in the higher unit area, improve the experience of Cell Edge User, and its cost is lower than the base station, therefore reasonably use relaying to replace the base station to carry out layout, can reach the purpose that reduces the cost of arranging net.
It is a kind of in the cellular system of introducing relaying that the specific embodiment of the invention provides, in order to adjudicate the admittance control method whether user can insert, adopt relaying and the base stations united access of carrying out to adjudicate, during information that certain user in a relaying receives its overlay area asks to insert, resource requirement or quality of service requirement that traffic load that this relaying is current with it and request insert the user are sent to the base station, this base station is according to the current business information on load of this relaying, and in conjunction with the summation of the surplus resources of the surplus resources of base station self and these all relayings of base station coverage area, whether synthetic determination admits user's access request, afterwards result of determination is fed back to this relaying, the result of determination of this base station feedback is notified to the user by this relaying.
Consult the workflow diagram of Fig. 2 for the described admittance control method of first embodiment of the invention, at first, when at step S201, after relaying receives the access request that its compass of competency user sends, current business load and user's to be accessed resource requirement information is sent to the base station of this relaying of administration, as step S202, judge whether to admit this user's access by this base station.
In step S202, described relaying is specifically as follows two kinds to the mode of described base station reporting service load, a kind of is the access request that no matter whether receives the user, all reports the current business load to this base station periodically, to allow this base station understand the occupation condition of this relaying in real time; A kind of is only when this relaying receives the access request that the user sends, and just reports the current business load to this base station.
In addition, the characterizing method of the traffic load that reports to described base station of described relaying is specifically as follows: the total amount of statistics resource occupation of this relaying in the past period and the ratio of available resources quantity; Or the average transmission rate summation of all accessed users' acquisitions under statistics interior this relaying administration of the past period and the ratio of the transmission rate that the beehive network system resource is provided; Or the difference between the demand summation of the statistics average transmission rate summation that the accessed user obtains in the past period and described accessed user's speed.
Described relaying is quality of service requirement (qos requirement) or resource requirement quantity to the user's to be accessed that described base station reports resource requirement information.Qos requirement comprises information such as the service speed, delay requirement of customer service application to be accessed, and this relaying can directly be transmitted this user's to be accessed qos requirement to this base station; Resource requirement quantity is that this relaying is transmitted to this base station with it after also can converting out this resource requirement quantity according to this user's resource needed quantity to be accessed of service of this user's to be accessed qos requirement and channel condition conversion.
At step S203, described base station receives the current business load of described relaying transmission and user's to be accessed resource requirement information;
Afterwards, enter step S204, the surplus resources quantity that described relaying is judged in described base station whether and the difference between user's resource needed quantity to be accessed whether greater than one first default value, in order to judge whether allow this user to insert this relaying according to the surplus resources of this relaying.If the surplus resources quantity of this relaying of judgement and the difference between this user's resource needed quantity to be accessed are greater than this first default value, then the judgement of accepting this user's request is made in this base station, allow this user to be accessed to insert this relaying, also be execution in step S206, this base station feeds back to this relaying with this result of determination afterwards, and this result of determination is sent to this user to be accessed by this relaying, execution in step S208, and before this relaying feeds back to user to be accessed with result of determination, this relaying at first distributes control channel (or directly dividing the system resource that is used in the transmission data) and corresponding software and hardware resources for this user to be accessed, notify this user to insert afterwards, follow-uply will be used in the system resource of transmitting data or the system resource that is used to transmit data that the user directly uses distribution for this user divides by this control channel.
If in step S204, judge that the surplus resources quantity of described relaying and the difference between user's resource needed quantity to be accessed are less than described first default value, the present residual resource summation of other relayings and this base station self under its compass of competency is further detected in then described base station, judge that the surplus resources quantity of this base station and all relayings and the difference between the required resource quantity of this user to be accessed whether greater than one second default value, also are execution in step S205;
If the judged result of step S205 is a "Yes", the difference that also is the surplus resources quantity of all relayings under the administration of described base station and described base station and user's resource needed quantity to be accessed is greater than second default value, then the judgement of accepting this user's request is made in this base station, execution in step S206, and result of determination is fed back to this user's to be accessed relaying, self and other relayings reclaim resources from this base station simultaneously, and this relaying of inserting to this user the resource allocation of reclaiming; This relaying feeds back to this user with the result of determination of this base station, execution in step S208, and in this step, this relaying also upgrades its resource pool, for this user to be accessed distributes control channel (or directly dividing the system resource that is used in the transmission data) and corresponding software and hardware resources, notify the user to insert, follow-uply will be used in the system resource of transmission data or the system resource that is used to transmit data that this user can directly use distribution for this user divides by this control channel.
If the judged result of step S205 is a "No", the difference that also is the surplus resources quantity of all relayings under the administration of described base station and this base station and user's resource needed quantity to be accessed is less than second default value, then the judgement that refusal is accepted this user's request is made in this base station, execution in step S207, this base station feeds back to this relaying with this result of determination afterwards, and this result of determination is sent to this user to be accessed, execution in step S208 by this relaying.
In addition, in step S206, when the judgement of accepting user request is made in this base station, also to set up the communication resource between base station and the core net for this user.
Based on this, the described admittance control method of first embodiment of the invention, introduce the base station and carry out the access judgement, when a certain relaying can not insert the user inadequately owing to own resource, the summation of himself the surplus resources and the surplus resources of other relayings under the described base station administration can be detected in the base station, comprehensively judge whether to admit described user's access request, and be relay distribution resource under the user to be accessed, thereby the resource of system is fully used, and effectively improve the success rate of user when inserting, and then the satisfaction when increasing the user and inserting.
Consult the workflow diagram of Fig. 3 for the described admittance control method of second embodiment of the invention, consult this figure, in a second embodiment, when at step S301, after relaying receives user's access request, at first the relaying of asking to insert by this user judges whether to accept this user's to be accessed request, execution in step S302, in this step, this relaying judges according to resource operating position of himself and this user's to be accessed resource requirement information, judges that whether the surplus resources quantity of this relaying and the difference between the required resource quantity of this user to be accessed are greater than described first default value; If judged result is for being, then this relaying is made the judgement of accepting this user's request to be accessed, execution in step S306, and this result of determination sent to this user to be accessed, be step S308, and this relaying distributes control channel (or directly dividing the system resource that is used in the transmission data) and corresponding software and hardware resources for this user, and notify the user to insert, simultaneously with the base station of this relaying of result of determination notice administration, by the base station be responsible for setting up and core net between the communication resource.
If in step S302, described relaying judges that the surplus resources quantity of this relaying and the difference between the required resource quantity of described user to be accessed are less than described first default value, then this relaying is made refusal and is accepted the judgement that this user inserts request, execution in step S303 afterwards; At step S303, this relaying sends to current business load and this user's to be accessed resource requirement information the base station of this relaying of administration.
At step S304, described base station receives the current business load of described relaying transmission and user's to be accessed resource requirement information.
At step S305, current business information on load that described base station provides according to described relaying and described user's to be accessed resource requirement information are done further judgement, and detect the present residual resource summation of other relayings and this base station self under its compass of competency, judge that the surplus resources quantity summation of this base station and all relayings and the difference between the required resource quantity of this user to be accessed whether greater than second default value, also are execution in step S305;
If the judged result of step S305 is a "Yes", the difference that also is the surplus resources quantity of all relayings under the administration of described base station and described base station and user's resource needed quantity to be accessed is greater than one second default value, then the judgement of accepting this user's request is made in this base station, execution in step S306, and result of determination is fed back to this user's to be accessed relaying, self and other relayings reclaim resources from this base station simultaneously, and the relaying of inserting to this user the resource allocation of reclaiming; This relaying feeds back to this user with the result of determination of this base station, execution in step S308, and in this step, this relaying also upgrades its resource pool, for this user to be accessed distributes control channel (or directly dividing the system resource that is used in the transmission data) and corresponding software and hardware resources, notify the user to insert, follow-uply will be used in the system resource of transmission data or the system resource that is used to transmit data that this user can directly use distribution for this user divides by this control channel.
If the judged result of step S305 is a "No", the difference that also is the surplus resources quantity of all relayings under the administration of described base station and described base station and user's resource needed quantity to be accessed is less than one second default value, then the judgement that refusal is accepted this user's request is made in this base station, execution in step S307, this base station feeds back to this relaying with this result of determination afterwards, and this result of determination is sent to this user to be accessed, execution in step S308 by this relaying.
The described admittance control method of second embodiment of the invention, judgement at first, judge whether to allow the user to insert, when can insert the user by relaying according to the current resource user mode of relaying, the user can be fed back to rapidly, thereby the time delay that the user inserts can be reduced; When the current resource of relaying does not allow the user to insert, further carry out synthetic determination by the base station, the base station according to himself surplus resources with and the compass of competency under the summation of surplus resources of other relayings, whether synthetic determination can insert the user, and be user resource allocation, therefore can effectively improve the success rate that the user inserts, the resource of system is fully used, thereby also can improve the satisfaction of system user.
Therefore, comprehensively the above, the described control method of the specific embodiment of the invention, adopt base station and relaying to carry out the mode of cascading judgement, can effectively improve the success rate of user when inserting, the satisfaction when increasing the user and inserting, and improve usage factor of system resource simultaneously.
