Description
Technical field:
The present invention relates to the mobile communication technology field, be meant a kind of method of in mobile communication, using data terminal equipment AT interface processing circuit domain voice service affair especially.
Background technology:
Along with development of wireless communication devices, various wireless products are increasingly extensive such as the application of products such as wireless network card.There are many products between data terminal equipment (DTE) and data communications equipment (DCE), to use the AT interface command to carry out communication interface." data terminal equipment " is meant the data processing equipment type with easy-operating man-machine interface (or keyboard), as PC." data communications equipment " is meant foundation, keeps or stop the device type of data link, as wireless network card.
In the 3GPP agreement, pair part that the AT order defines is arranged specially.But calling for circuit domain, initiatively discharge the situation of link for the other side, not having special AT orders and handles, but the return value of being used as the order ATD that sets up link is handled, but so, can cause data terminal equipment will in connection procedure, wait for returning of ATD always,, reduce availability so can not well carry out operation such as state switching.
Now, a kind of as the telecommunications supplementary service of the MPTY function in the wireless telecommunications by extensive use gradually.The definition of MultiParty Service is: the calling of a maintenance and the calling of an activation are arranged among the mobile subscriber, and each calling is all replied, this mobile subscriber can carry out MultiParty Service so, in case be activated in many ways, far-end can be added into, disconnection or separation (from Multi-Way Calling, separate, but still keep being connected) with this user.When the contracted user initiates MPTY, network will be linked this user and all far-ends in the Multi-Way Calling, but this user and all far-end mutual communication to each other.In the MPTY process, if the words of a square tube wherein are by initiatively on-hook of the other side, this moment, portable terminal received the message of on-hook from air interface, but there is not special description in agreement because of AT order for this part yet, so it is that in the MPTY which side hung up the telephone that the method for needing is discerned, thereby carries out correct state transition.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of method is provided, and solves data terminal equipment under the situation that the other side initiatively discharges the situation of link or a side is initiatively hung up in MPTY, can in time carry out the state switching.
The present invention solves processing to onhook event by a kind of expansion AT command, and expansion AT command of definition is used for sign and receives onhook event earlier; Data communications equipment will be called out link information and be increased in the call list; When receiving the incident that disconnects connection in MPTY, data communications equipment inquires the calling sequence number and the described expansion AT command of the connection of current disconnection and forms a new order according to the stored calls list information, send to data terminal equipment; After data terminal equipment receives this order,,, learn the information that corresponding user has broken from network, thereby switch current state according to the calling sequence number in the order by resolving this order.
In common conversation, data communications equipment is received certain user's calling or data communications equipment active call user, after link connects, data communications equipment is increased to this link information in the call list of oneself, and data terminal equipment can be found the calling sequence number of this calling from data communications equipment by the order of 3GPP agreement regulation.
When data communications equipment and a plurality of user carry out MPTY, in the call list of data communications equipment, safeguard many call-informations, data terminal equipment uses the order of 3GPP agreement regulation can obtain them to distinguish corresponding calling sequence number.
The present invention is used for the information that data communications equipment informs that the communication terminal equipment link disconnects by having expanded a new order, can in time the calling party who disconnects be switched.Make the processing of speech events more clear, succinct.
Description of drawings:
Fig. 1 is the connection layout of data terminal equipment and data communications equipment;
Fig. 2 is a flow chart of the present invention.
Embodiment
Fig. 1 is the connection layout of data terminal equipment and data communications equipment; Module 1 is a data terminal equipment among the figure, and module 3 is a data communications equipment, and data terminal equipment and data communications equipment are mutual by AT order (2).Module 5 is actual mobile network, and module 3 data communications equipments and network are mutual by air interface (4).
Fig. 2 is a flow chart of the present invention.Pre-defined AT order, for example HANGUP gives data terminal equipment with this AT command report, notifies the terminal equipment link to disconnect.
After data terminal equipment was received this AT order, just knowing had calling to disconnect.But if MPTY, phone has been hung up in which side of knowing that we can not be clear and definite, and in order to solve in the MPTY the identification problem of on-hook side, we expand this order, have increased the calling sequence number of on-hook side.Call out sequence number and be the numbering of the call list of stipulating in the 3GPP agreement, comprise own calling of initiatively transfering to and the calling that receives in the call list, this tabulation sequence number is since 1.
When increased the calling sequence number in the HANGUP order after, wireless telecommunications system sends to data terminal equipment with this AT order, after data terminal equipment is received this AT order then, finds the call information of this calling sequence number correspondence.Need not then more to judge again, just can learn which calling breaks from network, handles getting final product accordingly.Thereby simplified handling process, made the processing of speech events more clear, succinct.
Being divided into two kinds of implementations below is described:
First kind of implementation, in the common conversation:
Wireless telecommunications system receives the calling or the wireless telecommunications system active call party A-subscriber of party A-subscriber's (number is 02912345678), and after link connected, data communications equipment was increased to this link information in the call list of oneself.
Data terminal equipment can be found the calling sequence number of this calling from data communications equipment by the AT+CLCC order of 3gpp agreement regulation:
+CLCC：1，1，0，0，0，″02912345678″，128，″80529E516C5BA4″
According to agreement, first parameter of CLCC order return results is called out sequence number exactly, and the connection sequence number of learning the party A-subscriber thus is 1;
When the data communication module receives the incident that connects that disconnects from air interface, the calling sequence number that to can find the connection of current disconnection according to the stored calls list information is 1, use this sequence number and HANGUP to form AT order: hangup:1, data terminal equipment is issued in this AT order, after data terminal equipment has received this AT that reports order, by resolving this order, according to the calling sequence number that obtains, learning that user A has disconnected with oneself from network is connected, and switches current state in view of the above to idle condition.
Second kind of implementation, in the MPTY:
As wireless telecommunications system and party A-subscriber's (number is 02912345678) and party B-subscriber's (number is 02922345678) when carrying out MPTY, will safeguard two call-informations in the call list of data communications equipment.And the call list that data terminal equipment uses the AT+CLCC order to find is:
+CLCC：1，1，0，0，0，″02912345678″，128，″80529E516C5BA4″
+CLCC：2，1，0，0，0，″02922345678″，128，″80529E516C5BA4″
Data terminal equipment can obtain these two numbers and they distinguish corresponding calling sequence number:
It is 1 that the party A-subscriber calls out sequence number
It is 2 that the party B-subscriber calls out sequence number
When the data communication module receives the incident that disconnect to connect from air interface, the calling sequence number that will can find the connection of current disconnection according to the stored calls list information is 2, forms the AT order:
hangup：2
And this AT order issued data terminal equipment, after data terminal equipment has received this AT that reports order, will be according to calling out sequence number, learn user B from network and own disconnection be connected, switch current state in view of the above and arrive corresponding state.
