Abstract
The present invention discloses a method for automatically reregistering PTT of a wireless communication terminal. After an IP address of a wireless communication terminal is recovered or the terminal is logged out, the wireless communication terminal can automatically register to obtain the IP address and build communication with a PTT server, so that users can normally use the PTT function of the terminal. The method ensures that the PTT of a wireless communication terminal is always in an on-line state and keeps connection. The course of automatic register is simple and quick, which brings much convenience to terminal users.
Description
Technical field
The invention belongs to the mobile communication technology field, more specifically to the solution of the wireless cluster communication terminal registration of public's mobile system.
Technical background
The realization of group service is that a plurality of intercoms are formed a wireless dispatch system, need not network, just can use under the situation that need not to apply for a license, and is therefore used widely in a lot of industries, department; For go out, activity such as shopping brought very big facility and enjoyment.But the wireless dispatch system coverage of not having network support is little, and the availability of frequency spectrum is low, also can't guarantee at aspects such as safety, management.For this reason, the large-scale cluster system of network support occurred having, by common spectrum and facility, the interconnected area of coverage is to obtain the bigger coverage and the frequency spectrum of high usage.Group system need be set up wireless subsystem (RFSS), integral subsystem (DSS) and interconnection subsystem (ISS); By wired, wireless transfer channel each zone is linked to each other, can handle each interregional call setup, user's registration, control and management etc.
But public mobile network comprises that GSM and cdma network have wide area roaming, toll message, and advantage such as professional abundant is that existing group system institute can't provide, and as if public mobile network and group system being combined, will make mobile communication convenient.
The PTT business that occurs realizes being similar to the function of group system business in the public's mobile radio system at present, for the group communication of setting up fast provides safe control and scheduling mechanism, and utilize current public network advantages and business, merge, enrich the business of group system, need not other establishing network, be general wireless dispatch system and group system realization wide area roaming and toll message, and the certain safety and the function of control and management are provided.
The Chinese meaning of PTT (push to talk) is a press-and-talk, also is PTT.Be a kind of technology based on VOIP (voice over IP), the function of similar intercom.The user only need just can carry out session services with the other side by a key, and PTT can also realize the group calling function, carries out one-to-many directly conversation simultaneously, especially is fit to needs and group or the individual user who frequently is interrupted conversation.PTT is a business of setting up conversation in the mobile communication fast, utilizes this technology, can realize one to one or the cluster service function of one-to-many in the scope that cdma network covers very easily.
The PTT function only could be used after the terminal registration success, because this technology is based on the technology of VOIP, must obtain an IP address during registration.But in present wireless network resource, the IP address is very rare, and terminal is after idle a period of time, and the base station can be regained the IP address of this terminal.In ptt server, the control resource is also relatively more rare, and behind the certain hour, ptt server also can be this terminal log-down excessively.
Summary of the invention
Purpose of the present invention, just be to solve portable terminal after idle a period of time, can't use the problem of PTT function, propose the automatically heavy method of registration of a kind of radio communication terminal PTT, when the IP address of wireless communication terminal is recovered or after terminal is canceled, wireless communication terminal can be set up new registration procedure automatically, obtain the IP address, set up with ptt server and communicate by letter, the user can normally use the PTT function of terminal like this, accomplish onlinely always, keep to connect.Automatically heavy enrollment process is simply quick, brings bigger convenience to the terminal use.
After wireless communication terminal is canceled, carry out the method that PTT heavily registers automatically, may further comprise the steps:
(1) ptt server sends signaling by network to wireless communication terminal, notifies it to be canceled;
(2) wireless communication terminal is received signaling, judges whether its IP address is recovered, if be recovered, set up PPP and connects, and obtains its IP address and sends the registration request, if be not recovered, directly sends the registration request;
(3) the ptt server authentication is passed through, and issues correct response of wireless communication terminal;
(4) wireless communication terminal is received the response of ptt server, sets up communication.
Because in wireless network, the control Resources Department of IP address and ptt server is relatively more rare, the connection of wireless communication terminal and registration request may be rejected, according to above method, if connect or registration request failure, just wireless communication terminal restarts to connect or registration, so just there is a problem, if present network condition is very bad, connect or registration request failure always, then the registration of wireless communication terminal can repeat down always.Cause the quick minimizing of terminal battery electricity quantity like this and might influence other operation.In order to address this problem, we can take such countermeasure, if wireless communication terminal is continuous, (be generally 3 times) registration failure several times, illustrate that present network condition is very bad, terminal stops automatically the heavily step of registration, and prompting user PTT function is unavailable on display screen, if the user need use the PTT function, then manually initiate registration over time.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is connection side's block diagram of the present invention;
Fig. 2 is that wireless communication terminal IP of the present invention address is recovered the flow chart that heavily register automatically the back;
Fig. 3 is that wireless communication terminal of the present invention is canceled the flow chart that heavily register automatically the back.
Embodiment
As shown in Figure 1, the PTT business is that the group service function is provided on public cellular network, do not need to build special-purpose cluster network, the PTT business just can be carried out on present CDMA1X network, as a kind of value-added service, owing to the restriction of resources such as the time delay that is subjected to existing network, bandwidth, the group number of PTT, group's capacity have certain restriction.The CDMA1X network equipment comprises the BTS base station transceiver, BSC base station controller, PCF (Packet control function) and PDSN (Packet data service node).Ptt server is responsible for handling the SIP signaling from the PTT terminal use, comprises PTT user's registration, group call process etc., provide the interface of network management and configuration the PTT business to be configured to system manager or dispatcher, simultaneously, provide user rs authentication and billing function, AAA is an AUC.The PTT wireless communication terminal possesses PTT talk button and hand-free function.
As shown in Figure 2, wireless communication terminal is because the free time of a period of time, called out the back free time 20 minutes such as hanging up, its IP address is recovered, at this moment signaling is sent to wireless communication terminal in the base station, notify its IP address to be recovered, wireless communication terminal is received signaling, set up PPP and connect, obtain the IP address, wireless communication terminal sends the registration request to ptt server, the ptt server authentication is passed through, issue correct response of wireless communication terminal, wireless communication terminal is received the response of ptt server, sets up communication.The success of terminal registration this moment, this terminal just can have been used the cluster service function.
The function that PPP (Point-to-Point Protocol peer-peer protocol) obtains the IP address is realized by ppp protocol.
As shown in Figure 3, wireless communication terminal after wireless communication terminal is canceled, carries out the method that PTT heavily registers automatically because free time or the other reasons of a period of time may be nullified by ptt server, may further comprise the steps:
Ptt server sends signaling by network to wireless communication terminal, notifies it to be canceled; Wireless communication terminal is received signaling, judges whether its IP address is recovered, if be recovered, set up PPP and connects, if be not recovered, sends the registration request; The ptt server authentication is passed through, and issues correct response of wireless communication terminal; Wireless communication terminal is received the corresponding of ptt server, sets up communication.Can normally use the group service of PTT.
If present network condition is very bad, connection that wireless communication terminal is continuous 3 times or registration request are all failed, in order not influence the electric weight of other operation and saving end cell, terminal stops automatically the heavily step of registration, and prompting user PTT function is unavailable on display screen.
