Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms first and second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to the listed steps or elements but may include steps or elements not expressly listed.
The communication system aimed at in the embodiment of the invention can comprise a base station, a transmitting terminal and a receiving terminal, wherein the transmitting terminal is used for transmitting voice information to the receiving terminal through the base station, and the base station realizes the establishment of communication service channels of the transmitting terminal and the receiving and forwarding of the voice information.
The method generally comprises the steps that inter-cell switching is carried out in the voice communication process between terminals, for the cell switching process in voice transmission, a passive transmission stopping mode is adopted, namely, when the terminal detects that the field intensity of the terminal is weak or the field intensity of the adjacent station is strong, a signaling request non-participating station service channel (P_EMSU_RESELECT signaling) is embedded in a voice super frame of the local station service channel, after the system processes the signaling, non-participating station service channel information is acquired, RC (reverse information) is issued to interrupt the transmission of the terminal, the terminal is switched to a receiving state to acquire the non-participating station service channel information (P_BCAST signaling) broadcasted by the base station, and the terminal is switched to the service channel after receiving the non-participating station service channel information, and retransmits a voice head, an encryption head and voice.
The other is to actively stop transmitting, when the terminal detects that the field intensity of the own station is weak and the field intensity of the adjacent station is strong, the terminal actively stops transmitting voice, requests a service channel (P_RESELECT signaling) of a non-participating station on the service channel of the own station through complete signaling, and then the terminal is switched to a receiving state; after the system processes the signaling, it obtains the non-participated station service channel information, broadcasts the non-participated station service channel information (P_BCAST signaling), and after receiving it, the terminal switches to the service channel to retransmit the voice header, encryption header and voice.
However, in both existing schemes, there is a process that the terminal changes from a voice transmitting state to a signaling receiving state and retransmits the voice header and the encrypted header information, so that the foregoing process may cause discontinuous voice transmission, and word dropping occurs, which affects the user experience.
Accordingly, in an embodiment of the present invention, there is provided a transmission handover method, referring to fig. 1, which shows a flow chart of the method when applied to a base station, the method includes:
s101, receiving a service channel request instruction of a target base station.
The traffic channel request command is a command that the transmitting terminal requests information by embedding the base station in the voice superframe under specific conditions. The voice super frame is a group of voice frames, so that information can be conveniently embedded.
When the transmitting terminal detects that the field intensity of the transmitting terminal is weak and the field intensity of the neighboring station is strong, a signaling request non-participating station (wherein the non-participating station refers to a base station except for the base station to which the transmitting terminal is currently connected) is embedded in a voice super frame of the traffic channel of the transmitting terminal (P_EMSU_RESELECT signaling).
S102, processing the service channel request instruction to obtain the service channel information of the target base station. The target base station service channel information is the service channel information of the base station to which the transmitting terminal is to be switched.
S103, feeding back the target base station service channel information to the transmitting terminal in a target mode, so that the transmitting terminal switches the voice transmitting service to the target base station service channel.
The target mode characterizes a mode of continuously issuing a plurality of reverse messages.
The base station processes the instruction after receiving the instruction to obtain the non-participating station service channel information, namely, the base station sends the instruction to the specific core network after receiving the service channel request instruction, so that the specific core network obtains the service channel information of the target base station and feeds back the information to the base station, and the base station obtains the service channel information. The transmitting terminal can be informed of the non-participating station service channel information by continuously transmitting a plurality of RC (reverse information), and the terminal switches to the service channel after receiving the information and then transmits voice, so that the voice continuity is ensured.
The method for sending channel information by the base station includes the following steps that the target base station service channel information is fed back to the transmitting terminal in a target mode, and the method includes the following steps:
if the adjacent time slot of the base station is idle, continuously transmitting reverse information in the adjacent time slot, so that the transmitting terminal obtains the service channel information of the target base station; and if the adjacent time slot of the base station is idle, transmitting reverse information in the adjacent time slot in a target period, so that the transmitting terminal obtains the service channel information of the target base station.
And if the adjacent time slot of the base station is busy, generating target information by embedding reverse information in the voice superframe of the adjacent time slot, and transmitting the target information to the transmitting terminal, so that the transmitting terminal obtains the service channel information of the target base station.
The base station continuously issues RC in two ways: the neighbor slots are busy or idle. When the adjacent time slot is idle, RC information can be continuously issued in the adjacent time slot, such as 4 continuous voice superframes, if more information is needed, the number of continuous RCs can be increased, as can be seen in FIG. 1, the RC information can be issued discontinuously, and the period is arbitrary, namely, RC information is issued in a determined target period, so that a plurality of RC information can be issued; when the adjacent time slot is busy, the RC information can be embedded in the F frame in the voice superframe of the adjacent time slot in fig. 2, the current service channel information needs to be formed by 4 RC packets, and similarly, a plurality of superframes can be expanded to contain more service channel information, and fig. 2 can be seen specifically. Fig. 2 (a) is a schematic diagram of transmitting RC information with idle neighbor time slots, and fig. 2 (b) is a schematic diagram of transmitting RC information with busy neighbor time slots. Note that if the voice super frame includes A, B, C, D, E, F frames, RC information may be embedded in frames other than the a frame, and since the first frame, i.e., the a frame, generally includes synchronization information having a specific function, RC information may be embedded in any one of B, C, D, E, F frames to facilitate the embedding of information.
The method of continuously transmitting a plurality of RCs (reverse signaling, without completely switching the receiving state between two time slots, and switching the receiving state between adjacent time slots of the transmitting time slot) is one of the innovative points of the present invention, and replaces the single signaling in the existing scheme, and in the single RC signaling transmitting process, the single RC signaling transmitting process interrupts the terminal transmitting, and the terminal switches from the voice transmitting state to the receiving state to acquire the non-participating station service channel information broadcasted by the base station. In the invention, by issuing a plurality of continuous RC signaling, the adjacent station service information can be issued by the way of RC packet without completely receiving the state in two time slots, and the terminal switches channels and keeps transmitting after completely receiving the information without switching to the receiving state and then switching channels through a single RC. The terminal is prevented from being in a receiving state in 2 time slots, so that continuous transmission of voice is continued.
Correspondingly, in the embodiment of the present invention, there is also provided a transmission handover method applied to a transmitting terminal, referring to fig. 3, the method may include the steps of:
s201, detecting field intensity information currently corresponding to the transmitting terminal;
s202, judging whether the field intensity information meets a specific condition, and if so, executing S203;
s203, sending a service channel request instruction to a base station;
the specific conditions comprise that the field intensity of the current corresponding base station is smaller than a preset first threshold value and/or the field intensity of the adjacent base station of the transmitting terminal is larger than a preset second threshold value;
s204, receiving target base station business channel information fed back by the base station, wherein the target base station business channel information is reverse information fed back by the base station in a target mode after receiving a business channel request instruction;
s205, switching the voice transmission service to the service channel of the target base station.
It should be noted that, the specific condition is a condition that the field intensity of the own station (i.e. the base station to which the transmitting terminal is currently connected) representing the transmitting terminal is weak and/or the field intensity of the neighboring station is strong, and the selection of the corresponding first threshold and the second threshold may be determined according to the information of the field intensity of the own station, or may be determined according to the communication requirement of the transmitting terminal.
After determining the traffic channel information of the target base station, the transmitting terminal may switch the currently connected base station to connect with the target base station, so as to continue to transmit voice information.
On the basis of the above embodiment, the sending a traffic channel request instruction to the base station includes:
and embedding a signaling request for requesting the target base station in a voice superframe of the service channel to generate a service channel request instruction.
To ensure successful handoff, the present invention also provides a process for ensuring handoff stability, the method further comprising:
transmitting a target channel request instruction to a base station, the target channel request instruction including specified handoff base station information;
and responding to the feedback of the base station to the transmitting terminal of the traffic channel information of the appointed cross-region base station, and switching the voice transmitting service to the traffic channel of the target base station.
In an embodiment of the present application, further includes:
the field intensity information meets the specific condition, and a first service channel request instruction is sent to the base station, wherein the first service channel request instruction is marked with information that the base station realizes switching to a target base station by sending a reverse information group in a service signal instruction;
and if the target base station service channel information fed back by the base station is not received or the field intensity of the base station corresponding to the transmitting terminal is smaller than a third threshold value, sending a second service channel request instruction to the base station, wherein the second service channel request instruction is marked with information for requesting the target base station, and the transmitting terminal is converted from a voice transmitting state to a signaling receiving state for the base station, wherein the third threshold value is smaller than the first threshold value.
In this embodiment, a seamless handover or a fast handover is implemented, i.e. marking corresponding information in the traffic channel may enable the base station to implement a corresponding handover scheme by performing the corresponding procedure, in this embodiment, marking in the first traffic channel request is that in the embodiment of the present invention, a seamless handover is implemented by sending an RC packet.
On the basis of the above embodiment, if the handover to the target base station is impossible by the first traffic channel request command, in order to ensure that the handover is successful, that is, the transmitting terminal can be switched from the current base station to the target base station, when the transmitting terminal does not receive the target base station channel information fed back by the base station or the field intensity of the base station corresponding to the transmitting terminal is extremely small, that is, is smaller than the third threshold, and the third threshold is smaller than the first threshold in the specific condition corresponding to the sending of the first traffic channel command. At this time, a second traffic channel request command is sent to the target base station, where the second traffic channel request command is marked with information requesting the target base station, that is, the transmitting terminal changes from a voice transmitting state to a signaling receiving state for the base station, and concretely, two modes may be included, on one hand, the transmitting terminal passively stops transmitting voice information, a traffic channel (p_emsu_response signaling) of a signaling requesting non-participating station is embedded in a voice superframe of a local station traffic channel, after the system processes the signaling, non-participating station traffic channel information is obtained, transmitting RC (reverse information) is issued to interrupt terminal transmission, the terminal changes to a receiving state to obtain non-participating station traffic channel information (p_bcast signaling) broadcasted by the base station, and after the terminal receives the voice information, the terminal switches to a traffic channel, and retransmits the voice header, the encryption header and the voice. On the other hand, the transmitting terminal actively stops voice transmission, requests a service channel (P_RESELECT signaling) of a non-participating station on a service channel of the self-station through complete signaling, and then the terminal is switched to a receiving state; after the system processes the signaling, it obtains the non-participated station service channel information, broadcasts the non-participated station service channel information (P_BCAST signaling), and after receiving it, the terminal switches to the service channel to retransmit the voice header, encryption header and voice.
I.e. the procedure may be seamless or fast-handoff, in particular by marking in the signaling p_emsu_reserve (traffic channel (p_emsu_reserve signaling)) when traffic channel information of non-participating stations is applied, so that the base station implements a seamless handoff scheme by means of issuing RC-packets, and marking in the p_emsu_reserve signaling so that the handoff is implemented by means of a fast handoff word scheme when no base station acknowledgement or field strength is continuously received until a handoff is necessary.
