Specific embodiments of the present invention have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
The session processing method provided by the invention can be applied to the broadband trunking communication system shown in fig. 2. As shown in fig. 2, the communication system includes: TCF, base Station (BS) and a plurality of terminal equipments (terminal equipment, TE), two TEs are exemplarily shown in fig. 2.
The TCF is used as a core network device of the broadband trunking communication system, and may process data sent by the BS, where the process includes, but is not limited to: store data, forward data to the remaining TCFs, forward data sent by the remaining TCFs to the BS.
Wherein the BS is used for, but not limited to: data sent by the TE is sent to the TCF, data sent by the TCF is forwarded to the TE, the TE is paged, registration, attachment, etc. are performed on the TE.
The TE can be a handheld station, a vehicle-mounted station, a data terminal or an individual backpack terminal. Taking the most number of handheld tables as an example, the mode of the handheld tables is mainly a large-size touch screen, and front and rear high-definition cameras and a large-capacity battery are configured. Some terminals are compatible with private network and public network frequency bands and support double-network double-standby.
It is understood that the TCF and BS, TE may communicate with each other via a wireless network.
It can be seen that, in the broadband trunking communication system shown in fig. 2, only one TCF, one base station, and a plurality of terminal devices under the base station are shown, in practical application, different TCFs may also communicate, as shown in fig. 3, there are two TCF entities TCF1 and TCF2, and two TCF entities may communicate between them, base station BS1 exists under TCF1, base station BS2 exists under TCF2, three terminal devices TE1, TE2, and TE3 are connected in BS1, two terminal devices TE4 and TE5 are connected in BS2, based on the broadband trunking communication system shown in fig. 3, any terminal device under BS1 may communicate with any terminal device under BS2, for example, TE1 and TE4 may communicate, TE1 may transmit data to BS1, BS1 may transmit data to TCF1, TCF1 may transmit data to TCF2, TCF2 may transmit data to BS2, BS2 may transmit data to terminal device TE4, and similarly, 4 may also transmit data to BS1, TE2, and TE1.
The foregoing TE-to-TE communication may be referred to as a session, the data sent may be voice data, the communication is SIP-based communication, SIP refers to a multimedia communication protocol established by the internet engineering task force (internet engineering task force, IETF), which is a text-based application layer control protocol for creating, modifying and releasing sessions for one or more participants, which may communicate by way of a single call or group call or a mixture of both.
When a session is performed between the TEs, each TCF (for example, TCF 2) locally stores corresponding session information, and after the TCF2 is restarted, the TCF2 can process the session information; while the remaining TCFs (e.g., TCF 1) in communication with the TCF2 also need to process session information on the TCF1 after detecting the TCF2 restart through heartbeat messages. In some cases, TCF1 cannot process session information on TCF1 in time. For example, as shown in fig. 4, when the restart is completed between the response message "200OK" replied by TCF2 and the transmission of the next heartbeat message by TCF1, TCF1 cannot determine that TCF2 is restarted, and thus cannot process the session information on TCF1 in time.
In order to solve the above-mentioned problem, as shown in fig. 5, the TCF2 according to the embodiment of the present invention sends notification information to the TCF1 after restarting, so that the TCF1 processes session information on the TCF1 according to the notification information. In this way, the TCF2 sends notification information to the TCF1 every time of restart, so that the TCF1 processes session information after each time of restart of the TCF2, and the problem that the TCF1 does not process session information due to the fact that the TCF1 does not detect the restart of the TCF2 through a heartbeat message in fig. 4 is avoided. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 6 is a flowchart of steps of a session processing method according to an exemplary embodiment, applied to a first cluster control function entity (hereinafter referred to as a first TCF), which communicates with a second cluster control function entity (hereinafter referred to as a second TCF), including S101 and S102:
s101, receiving notification information sent by the second TCF, wherein the notification information is used for notifying the first TCF of restarting the second TCF.
Wherein the first TCF is any TCF in the broadband cluster system that can communicate with the second TCF, and the second TCF is any TCF that can communicate with the first TCF.
In the embodiment of the invention, the notification information is information that the second TCF sends to the first TCF after restarting, and the second TCF deletes session information on the second TCF before restarting.
It may be understood that the notification information may be carried in any of the second TCF to the first TCF, and the notification information may be used as one of fields in the message, where the length of the field may be preset according to a rule, which is not limited in the embodiment of the present invention. For example, this field may be a bit, with a "1" representing that it has been restarted, and a "0" or other value representing that it has not been restarted.
Optionally, in an example of the embodiment of the present invention, the notification information is carried in a heartbeat message sent by the second TCF to the first TCF, where the heartbeat message includes, in addition to an optional TCF domain name, an optional TCF network protocol (internet protocol, IP) address, an optional TCF port, a starting TCF domain name, a starting TCF IP address, a starting TCF port, a destination TCF domain name, a destination TCF IP address, a destination TCF port, a session identifier, an allowed operation instruction, a maximum hop count, and a command sequence carried before. After the first TCF receives the heartbeat message carrying the communication information, it is necessary to perform not only processing of the session information but also conventional processing of the heartbeat message, for example, reply of the heartbeat message.
S102, responding to the notification information, and processing session information associated with the second TCF in the first TCF.
Specifically, firstly, session information of which TCF information is second TCF information is obtained from session information stored in a first TCF, and session information associated with the second TCF is obtained; then, the session information may be deleted from the first TCF, and transmission resources used by the session corresponding to the session information may be released.
In practical application, the session information can be deleted and the transmission resources can be released according to the rest of the session information.
Optionally, in an example of the embodiment of the present invention, S102 includes S1021:
s1021, according to the session type corresponding to the session information, processing the session information associated with the second TCF in the first TCF.
Among others, session types may include, but are not limited to: single call and group call. The session type usually exists in the session information, and can be determined from the number of the terminal devices in the session information, if the number of the terminal devices is 2, the session type is determined to be a single call; if the number of the terminal devices is more than 2, determining the session type as group call.
A session of the single call type is a session between two terminal devices for which both users can act as a calling party, e.g. for two terminal devices TE1 and TE4 as in fig. 3, user USR1 of TE1 can act as a calling party and user USR4 of TE4 can act as a called party. Both the calling and called subscribers may send voice data to each other, e.g., TE1 sends voice data of user USR1 to BS1, BS1 sends voice data of user USR1 to TCF1, TCF1 sends voice data of user USR1 to TCF2, TCF2 sends voice data of user USR1 to BS2, BS2 sends voice data of user USR1 to TE4, and TE4 plays the voice data to USR4. Similarly, the voice data of the user USR4 may be sequentially sent to TE1 through TE4, BS2, TCF1, and BS1, and the TE1 plays the voice data to USR1.
The group call type session refers to a session between more than two terminal devices, wherein a user of one terminal device is used as a main speaking user, and users of the other terminal devices are used as monitoring users, so that voice data of the main speaking user is sent to terminals of the other users through the terminal devices of the main speaking user. For group calls, there is a group control function (group trunking control function, G-TCF) as shown in fig. 7 for implementing data forwarding between the remaining TCFs, i.e. receiving data of one of the TCFs and forwarding the data to another one or more TCFs. It is understood that G-TCF is a central role. For a group call, its home subscriber is subscriber USR1 of TE1 shown in fig. 7, the listening subscriber is subscriber USR4 and USR6 corresponding to TE4 and TE6 shown in fig. 7, respectively, the voice data of USR1 is sent to BS1 through TE1, BS1 sends the voice data of USR1 to TCF1, TCF1 sends the voice data of USR1 to G-TCF, G-TCF sends the voice data of USR1 to TCF2 and TCF3, TCF2 sends the voice data of USR1 to BS2, BS2 sends the voice data of USR1 to TE4, TE4 plays the voice data of USR1 to subscriber USR4, TCF3 sends the voice data of USR1 to BS3, BS3 sends the voice data of USR1 to TE6, and TE6 plays the voice data of USR1 to subscriber USR6.
In practical applications, the transmission resources used by the links from TCF to G-TCF may be referred to as uplink transmission resources, and the transmission resources used by the links from G-TCF to TCF may be referred to as downlink transmission resources. For example, in the group call process, the transmission resources used by the links between TCF1 to G-TCF are uplink transmission resources, and the transmission resources used by the links between G-TCF to TCF2 and TCF3 are downlink transmission resources.
Based on the session type, the embodiment of the invention can process the session information and release the transmission resources according to the session type, wherein the released transmission resources comprise uplink transmission resources and downlink transmission resources.
Optionally, in an example of the embodiment of the present invention, the above S1021 includes S10211 to S10212:
s10211, if the session type corresponding to the session information is a single call type, releasing the target transmission resource between the first TCF and the second TCF, and deleting the session information in the first TCF, wherein the target transmission resource corresponds to the session information.
It will be appreciated that for a single call type session, there may be two TCFs, one of which is the TCF to which the base station to which the terminal device of the calling subscriber has access belongs, which may be referred to as the TCF of the calling subscriber, and the other TCF is the TCF to which the base station to which the terminal device of the called subscriber has access belongs, which may be referred to as the TCF of the called subscriber. The first TCF can be the TCF of the calling user, and the second TCF can be the TCF of the called user, so that the notification information is sent to the TCF of the called user after the TCF of the calling user is restarted, and the session information is deleted and the target transmission resource is released; or the first TCF may be the TCF of the called party, and the second TCF may be the TCF of the calling party, so that after the TCF of the called party is restarted, notification information is sent to the TCF of the calling party, so that the session information is deleted and the target transmission resource is released.
Wherein the target transmission resource is a transmission resource between a first TCF and a second TCF used by the session of the single call type. For example, as in the foregoing example of the session of the single call type between USR1 and USR4 in S1021, after TCF1 sends notification information to TCF2, TCF2 deletes session information of the session of the single call type in TCF2, and releases transmission resources of TCF1 to TCF2 occupied by the session and/or transmission resources of TCF2 to TCF1 occupied by the session.
S10212, if the session type corresponding to the session information is the group call type, processing the session information according to the type of the second TCF.
Wherein the types of the second TCF may include, but are not limited to: the TCF of the user is mainly spoken, the TCF of the user is monitored. In an embodiment of the present invention, when a second TCF of a different type is restarted, a first TCF in communication therewith may perform different processing. The TCF of the talkback user may also be referred to as H-TCF, and the TCF of the listening user may also be referred to as V-TCF.
Optionally, in an example of the embodiment of the present invention, the processing the session information according to the type of the second TCF in S10212 includes S102121:
s102121, if the second TCF is the H-TCF corresponding to the session information, releasing the target transmission resource from the second TCF to the first TCF, wherein the target transmission resource corresponds to the session information.
In a group call type session, when the H-TCF is restarted, the H-TCF acts as a second TCF, and the first TCF is the G-TCF because the H-TCF communicates with the G-TCF. For example, for the session example of the group call type in S1021 above, TCF1 is H-TCF, TCF1 sends notification information to G-TCF after restarting, and G-TCF releases transmission resources between TCF1 to G-TCF.
It may be appreciated that when the H-TCF is restarted, the H-TCF may not send data to the G-TCF any more, so that transmission resources from the H-TCF to the G-TCF used by the group call type session may be released, and at this time, session information of the session may not be deleted, and the session is in an idle state.
Optionally, in an example of an embodiment of the present invention, based on S102121, the method further includes S102122:
s102122, starting an idle timer, and deleting session information in the first TCF when the idle timer times out.
In the embodiment of the present invention, the idle timer is started while or after the session enters the idle state, the session is in the idle state before the idle timer times out, the session information in the first TCF is not deleted, and the session is in the end state after the idle timer times out, the session information in the first TCF is deleted.
Optionally, in an example of the embodiment of the present invention, the processing the session information according to the type of the second TCF in S10212 includes S102122:
s102122, if the second TCF is the G-TCF corresponding to the session information, releasing the target transmission resource between the second TCF and the first TCF, and deleting the session information in the first TCF, wherein the target transmission resource corresponds to the session information.
It will be appreciated that since the G-TCF is a central role in the session, the remaining TCFs are dependent on the G-TCF, so that the remaining TCFs need to process session information after the G-TCF is restarted.
Specifically, when a G-TCF restarts, it may send notification information to one or more TCFs with which it communicates, such that each TCF with which the G-TCF communicates releases transmission resources between the G-TCF and each TCF. The TCF that receives the notification information includes: the H-TCF, V-TCF, releasing the target transmission resources between the second TCF and the first TCF includes: and releasing the target transmission resource between the second TCF and the first TCF according to the type of the first TCF. When the TCF receiving the notification information is H-TCF, releasing transmission resources from the H-TCF to the G-TCF; and when the TCF receiving the notification information is V-TCF, releasing the transmission resources from the G-TCF to the H-TCF. For example, for the group call type session example in S1021, if the G-TCF is restarted, it sends notification information to TCF1, TCF2, and TCF3, TCF1 is H-TCF, which may release the transmission resources of TCF1 to G-TCF and delete the session information in TCF1, TCF2 and TCF3 are V-TCF, TCF2 releases the transmission resources of G-TCF to TCF2 and deletes the session information in TCF2, and TCF3 releases the transmission resources of G-TCF to TCF3 and deletes the session information in TCF 3.
Optionally, in an example of the embodiment of the present invention, the processing the session information according to the type of the second TCF in S10212 includes S102123:
s102123, if the second TCF is the V-TCF corresponding to the session information, releasing the target transmission resource from the first cluster control function entity to the second TCF, wherein the target transmission resource corresponds to the session information.
It is understood that the first TCF is a G-TCF because the second TCF is a V-TCF and the V-TCF communicates with the G-TCF. When the G-TCF receives the notification information of the V-TCF, the G-TCF releases transmission resources between the G-TCF and the V-TCF. In addition, since the V-TCF only receives data from the G-TCF, the restarting of the V-TCF does not affect the group call type session, the session remains in the original state, and the G-TCF does not delete the session information. For example, for the group call type session example in S1021 above, when TCF2 restarts, it sends notification information to G-TCF, which releases the transmission resources of G-TCF to TCF2, but does not delete session information on G-TCF.
