Description

Method and equipment for notifying speaking right information
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for notifying speech right information.
Background
Fig. 1 is a schematic diagram of an MBMS (Multimedia Broadcast Multicast Service) logical architecture; the M1 interface is a user plane interface defined between an eNB (base station) and an MBMS GW (gateway), and is used to provide point-to-multipoint user plane data transmission based on IP multicast between the MBMS GW and the eNB; the M2 interface is a control plane interface defined between the eNB and MCE (MBMS coordination entity), and it is used for MBMS session management function and MBMS scheduling information provision function; the M3 interface is a control plane interface defined between an MME (Mobility Management Entity) and an MCE, and is used for an MBMS session Management function.
In a multi-cell joint transmission mode, MBSFN (Multimedia Broadcast multicast service Single Frequency Network) refers to synchronous transmission in multiple cells at the same time and at the same Frequency (that is, cells in the same MBSFN area are all at the same Frequency); the method can save frequency resources and improve the utilization rate of frequency spectrum; the method requires that a plurality of cells simultaneously transmit the completely same content, so that a UE (User Equipment) receiver can regard a plurality of MBSFN cells as a large cell; thus, the UE will not only not suffer from inter-cell interference of neighboring cell transmissions, but will also benefit from superposition of signals from multiple MBSFN cells.
It should be noted that both the MBMS dedicated cell and the MBMS/unicast mixed cell may adopt the MBSFN transmission mode; in addition, if advanced UE receiver technology is utilized, the problem of time difference of multipath propagation can be solved, so that the intra-cell interference is eliminated; the diversity effect brought by the multi-cell same-frequency transmission can also solve the problems of blind area coverage and the like, enhance the reliability of reception and improve the coverage rate.
The trunking communication system communicates in a half-duplex mode, acquires and releases a control channel through a Push To Talk (PTT) key during working, the channel utilization rate is high, and the call connection is fast; and users in the group share the downlink channel, so that the resource utilization rate is high; the cluster communication system can ensure the privacy and the safety of the conversation through voice encryption; preferentially distributing channels for high-priority users or services; communication in an emergency state is ensured through a fail-soft function; and the flexible multi-level grouping scheduling command function is realized through dynamic recombination.
At the stage that the current trunking communication system is developed into a broadband trunking communication system, based on the most advanced wireless transmission technology, such as an LTE (Long Term Evolution) technology, the leap of various functions and technologies of the trunking communication system can be realized; the broadband trunking communication system has the characteristics of diversified service types, diversified transmission modes, large bandwidth and high transmission rate; and supported services include voice, data, video, etc.; the transmission modes comprise unicast, group calling, multicast and the like, wherein the unicast mode works in a full-duplex mode, and the group calling and the multicast mode work in a half-duplex mode.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:
in the prior art, if a multi-cell joint transmission mode is adopted to provide group call session service for a user, core network equipment cannot inform UE of a specific group of session right indication information related to the group call session; and in the absence of the talk right indication information, the UEs in the specific group cannot preempt the talk right by initiating the talk right preemption (only the UE with the talk right is allowed to speak).

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment of the invention provides a method for notifying speech right information, which can be applied to a broadband trunking communication system based on LTE, and is used for sending speech right indication information related to a group call session from core network equipment to access network equipment and sending the speech right indication information to UE by the access network equipment when a network side provides group call session service for the UE in a multi-cell joint transmission mode so as to meet the requirement of dispatching the speech right indication information in the broadband trunking communication system, as shown in figure 2, the method comprises the following steps:
step 201, a core network device obtains a talk right indication information for a specific group call session; the core network device may include, but is not limited to, an MME.
In step 202, the core network device notifies the MCE of the talk right indication information for the specific group call session.
In the embodiment of the invention, in order to notify the MCE of the speaking right indication information, a notification signaling of the speaking right indication information and information carried in the notification signaling need to be designed on an M3 interface; in addition, when the core network device sends the talk right indication information to the MCE, a transmission network carrying an M3 interface between the core network device and the MCE cannot guarantee that the notification signaling arrives in sequence, and once the notification signaling of the talk right indication information is out of order, the talk right state stored by the cluster UE will be wrong, so that the situation that the notification signaling of the talk right indication information is out of order needs to be avoided.
Based on the above considerations, the notifying, by the core network device, the MCE of the talk right indication information for the specific group call session includes: the core network equipment informs the MCE of the talk right indication information aiming at the specific group calling session through a group calling session related M3AP (M3 interface application layer) message; or, the core network equipment informs the MCE of the talk right indication information for the specific group call session through the M3AP message related to the non-group call session.
In the first mode, the core network device notifies the MCE of the talk right indication information for a specific group call session through a group call session related M3AP message.
In the embodiment of the present invention, the M3AP message related to the group call session includes but is not limited to: speaking Right Indication message; and the Speaking Right Indication message at least carries MME MBMS M3AP ID, MCE MBMS M3AP ID, TGID, Speaking Right; the MME MBMS M3AP ID represents a temporary identifier allocated to the group call session by the core network equipment in the group call session establishment process; the MCE MBMS M3AP ID represents the temporary identifier allocated by the MCE to the group call session in the group call session establishment process; the TGID represents a NAS (Non Access Stratum) layer identity of the group; the Speaking Right indicates the Speaking Right occupation condition of the current group, and the Speaking Right occupation condition specifically includes two states of occupied state and idle state.
As shown in table 1, is an example of a format of the Speaking Right Indication message.
TABLE 1
Further, after the core network device notifies the MCE of the talk right indication information for a specific group call session through the group call session related M3AP message, and before the core network device receives the response message of the group call session related M3AP message from the MCE, the core network device does not initiate the talk right indication procedure for the same group call session (i.e., refuses to send the talk right indication information for the same group call session).
In this embodiment of the present invention, the response message of the M3AP message related to the group call session includes but is not limited to: speaking Right Response message; and the Speaking Right Response message at least carries MME MBMS M3AP ID and MCE MBMS M3AP ID; and the MME MBMS M3AP ID represents the temporary identifier allocated by the core network equipment for the group call session in the group call session establishment process; the MCE MBMS M3AP ID indicates a temporary identifier allocated by the MCE to the group call session during the group call session establishment.

TABLE 3
It should be noted that before the core network device notifies the MCE of the talk burst indication information for a specific group call session through the non-group call session related M3AP message (i.e., before the core network device sends the Speaking Right Notification message), it needs to start the timer Time0, and before the timer Time0 times out, it does not send new talk burst indication information for a group with the same TGID identifier (i.e., it rejects sending new talk burst indication information for a group with the same TGID); further, the Time interval set by the timer Time0 needs to be long enough to ensure that the talk right indication information sent by the core network device does not reach the MCE before the previous talk right indication information.
In step 203, the MCE receives the talk right indication information for the specific group call session from the core network device. In the embodiment of the present invention, the receiving, by the MCE, the talk right indication information for the specific group call session from the core network device includes: the MCE receives M3AP information related to the group calling session from core network equipment, wherein the M3AP information carries speaking right indication information aiming at the specific group calling session; or, the MCE receives an M3AP message related to the non-group call session from the core network device, which carries the talk right indication information for the specific group call session.

In step 204, the MCE notifies the access network device of the talk right indication information for the specific group call session.
In the embodiment of the invention, in order to notify the access network device of the talk right indication information, a notification signaling of the talk right indication information and information carried in the notification signaling need to be designed on an M2 interface; based on the above considerations, the MCE notifying the access network device of the talk right indication information for the specific group call session includes: the MCE merges the talk right indication information for different group call sessions or different groups received from the core network device in an MCCH (multicast Control Channel) message update period, generates a talk right information list including the talk right indication information for a specific group call session, and notifies the access network device (e.g., eNB) of the talk right information list through a message related to a non-group call session.
In the embodiment of the present invention, the message related to the non-group call session includes but is not limited to: a speak Right Indication message; and the Speaking Right Indication message at least carries MCCH Update Time, MBSFN Area ID, and Speaking Right List; the MCCH Update Time indicates the Time when the talk right indication information is transmitted on the MCCH channel; the MBSFN Area ID represents an MBSFN Area identifier for transmitting the speaking right indication information; the speakerpight list is a speaking right information list, and each information item in the speakerpight list is used for indicating the NAS layer identification of a specific group (the group information is identified by using TGID) and the speaking right occupation condition of the current group (the speaking right state condition is identified by using speakrgight), and the speaking right occupation condition specifically includes both occupied state and idle state.
As shown in table 4, is an example of a format of the Speaking Right Indication message.
