Abstract
A calling resource managing method for microcellular system includes simultaneously creating all processes needed by n+l calls (where n is the number of channels supported by base station) when system is initialized, applying call resource when a call is initilized, applying call resource when a paging message is going to emit and the called user is in response, restoring all processes and associated data in relative call resource to initial state when call is finished, and ejecting the undesired call. Its advantages include high efficiency and durable stability of system.
Description
The present invention relates to the calling resource managing method in the radio communication micro cellular system, more specifically relate to the calling resource managing method in personnel hand system (the to call PHS in the following text) base station system.
For micro cellular system, its base station range is smaller, and the number of base stations in the General System is also many, therefore to the stability requirement of base station also than higher.Simultaneously because the channel number of a base station is limited, be assumed to be n, and some the time have and inevitably have m (the individual user of m＞n) attempts to set up on same base station call out simultaneously, limited by the limited number of channel, this moment, n calling should be accepted and set up in the base station, refusal (m-n) individual calling simultaneously.Existing calling system is in order to realize the control of above-mentioned call flow, in running, often call out and the release resource by setting up at any time, constantly create process and the end process realizes, this method causes memory overflow easily, influence the long-time stability of system, and lower efficiency, leading to system abnormity in order to handle abnormal conditions such as establishment process failure simultaneously, it is complicated to handle.
For overcoming above-mentioned shortcoming of the prior art, the invention provides a kind of reliable and stable calling resource managing way.
For realizing purpose of the present invention, provide following technical scheme:
The present invention creates all processes when system start-up, and with all with call out the call resources that relevant process is divided into one group of group, in calling procedure, be that unit carries out with the call resources, apply for call resources when initiating when calling out, call release resource during end of calling returns to init state with the process related data simultaneously; The distribution of call resources and release are controlled realization by calling out the master control process.
The channel number that base station is supported is set at n, that is to say that a base station can only accept n calling at most simultaneously, and calling out then for all the other must refusal, discharges and produces idle channel up to having to call out.The present invention creates (n+1) group calls in several process resource when system start-up, and allow all calling control subsystem all be in suspended state, after the system start-up success, n group resource is wherein adjourned to operating state, and remaining one group of process resource still is in suspended state, is referred to as to hang up resource; When a calling is assigned to the hang-up resource, this calling will be rejected, therefore this call resources can be distributed to the calling that all need be refused, most typical situation is exactly as m (m＞when n) individual calling is initiated, (m-n) individual call request is all sent to the associated process of this call resources.The suspended state of when operation force to be released in the base station all calling control subsystem all being moved into is refused all call requests.
In order to further specify method of the present invention, the basic conception that wherein relates to is described as follows: a group calls in several resource: it is necessary to constitute a full call institute, and all separate processes are collectively referred to as " a group calls in several resource " between difference is called out simultaneously.Each is called out all needs one group of independently call resources.
Being implemented as follows of purpose of the present invention:
1) system initialization: system's electricity starts, and creates and realizes that simultaneously n+1 is called out needed all processes, and process is in suspended state; The associated process of call resources in the system in case create is finished, and its corresponding relation with call resources number is also just established, and number can find process numbers that all are correlated with from database by call resources that is:; Wherein n puts calling party's number of being supported for system's full configuration; After the system initialization success wherein the associated process of n group calls in several resource be changed to operating state, still have all associated process of a group calls in several resource to be in suspended state this moment;
2) user makes a call, when receiving user's setup requests, call out the master control process and inquire if idle available call resources is arranged, this setup requests is transmitted to the associated process of this call resources, all processes by this call resources inside of calling out cooperate independently to be finished; Do not have idle available call resources if calling master control process inquires, then setup requests is forwarded to the associated process of hanging up call resources, by the associated process refusal calling this time of this call resources inside;
3) when the paging breath of calling called subscriber requires to send, call out the master control process and receive the called request of paging, directly send beep-page message by physical layer behind the framing; The called subscriber can initiate a call request earlier when called subscriber answer, just applies for call resources this moment;
4) customer call finishes, and after the associated process of call resources inside was received and called out Release complete, notification call master control process discharged this call resources by calling out the master control process, this call resources is changed to the free time that is:, waits for next time and calls.Wherein all processes of call resources inside should be got back to init state after calling out the release end, and this is by process status
Machine guarantees.
Method provided by the present invention proposes just to create all relevant processes when system start-up, comprises that full configuration deposits all processes that can realize normal call and one group and is used to refuse all processes that all do not expect " the hang-up call resources " called out.Process is not created with call setup or end or is finished, and the maximum like this leakage that prevents internal memory has guaranteed the long-time stability of system; Owing to need not constantly to create process and end process, improve efficient simultaneously, greatly reduced the abnormality processing that causes owing to the process creation failure.
Below in conjunction with drawings and Examples, further specify technical scheme of the present invention.
