Fig. 3 is the method flow diagram of a kind of retransmitting message of one embodiment of the invention explanation.Refer to Fig. 3,
The method of the present embodiment is applicable to user's equipment 110 of the communication system 100 and Fig. 2 of Fig. 1.Hereafter
In, by the every component description embodiment of the present invention in collocation communication system 100 and user's equipment 110
Described method.Each flow process of this method can adjust therewith according to implementing situation, and is not limited in
This.
In step S310, processor 116 please by the mandate that transceiver 113 transmits for proximity service
The first message asked, and start the first timer.Specifically, in the direct heuristic process of ProSe,
User's equipment 110 receives after upper strata (for example, ProSe application program) is for the request of declaration,
Can carry out announcing request process, to obtain at the user's equipment room with the service enable of other proximity
The upper proximity service announced of interface (for example, the PC5 interface between user's equipment 110a and 110b) should
With procedure code (ProSe Application Code).Now, user's equipment 110 can transmit e.g.
Explore the first message of request (DISCOVERY_REQUEST) to ProSe function 135 (for example,
By PC3 interface), to obtain at public Land Mobile Network (the Public Land Mobile of registration
Network, be called for short PLMN) mandate.Wherein, this first message for example includes that proximity is served by journey
Sequence identification code (ProSe Application identification (ID)), issued transaction identification code (transaction
ID) it, is set to instruction (command) and user's EIC equipment identification code of " announcing (announce) "
Data such as (UE identity).
Additionally, react on the transmission of the first message, (for example, processor 116 starts the first timer
T3901).The clocking value of this timer e.g. 30 seconds, 40 seconds or 60 seconds etc..
It should be noted that, the signaling paths between user's equipment 110 and ProSe function 135 may pass through
One or more network entities (for example, MME the 131st, HSS 133 etc.), the embodiment of the present invention not office
Limit above-mentioned transmission path or method.
Then, in step S330, if being received by transceiver 113 not yet when the first timer expires
To the second message in response to the first message, then start the second timer.Before the second timer expires,
Do not retransferred the first message by transceiver 113.Specifically, base station the 120th, core network 130
It may happen that any network problem, or and user's equipment 110 between line generation problem, this will
The second message causing user's equipment 110 cannot receive in response to the first message (for example, explores sound
Answer (DISCOVERY_RESPONSE)).Owing to these networks or wiring issue possibility will not be immediately
Recover normal, if retransmitting the first message when therefore the first timer expires immediately, then may or cannot be
First timer receives the second message before expiring.So constantly retransmit the first message at short notice, probably
Cause the power of battery improper consume and cause signaling traffic burden.Accordingly, the embodiment of the present invention just additionally opens
Dynamic second timer (for example, T3902), to allow user's equipment before the second timer expires, no longer
Transmit the first signal.In one embodiment, user's equipment 110 can wait until that network or wiring issue recover
After normal and when the second timer expires, just transmit the first message by transceiver 113 and reinitialize
Announce request process, and restart the first timer.
In another embodiment, before the second timer expires, processor 116 is also by transceiver 113
Close and existing safe line between ProSe function 135.Therefore, during this period of time, transceiver 113
Will not receive or not react on the second message that ProSe function 135 is replied.And arrive at the second timer
During the phase, processor 116 can be set up by transceiver 113 again and safety new between ProSe function 135 connects
Line, with first message that retransfers.
In further embodiments, the clocking value of the second timer is also multiplied by multiple value (example by processor 116
Such as the 2nd, 3 or 5 etc.).Aforementioned network or wiring issue may through the first timer and the second timer,
Still cannot revert to normal condition.In this scenario, user's equipment 110 may or cannot receive
Second message.Accordingly, when next first timer expires, processor 116 just extends second with multiple
The clocking value of timer, to allow user's equipment 110 extend the time that Holding Problem recovers.And at some
In embodiment, the second timer also has timing maximum (for example, 30 minutes, 40 minutes etc.).If
The clocking value of the second timer is more than timing maximum, then processor 116 is by the clocking value of the second timer
It is set to timing maximum.
For example, the initial clocking value of the first timer and the second timer is 1 minute, and second
When secondary first timer expires, if user's equipment 110 does not receives the second message, processor 116 yet
Just the clocking value of the second timer is set to 2 minutes, and starts the second timer.And third time, the 4th
The first secondary timer expire and afterwards just the rest may be inferred extend the second timer expiration time.Assume
Timing maximum is 30 minutes, if when the clocking value of the second timer is also 30 minutes, then again next
When secondary first timer expires, then processor 116 clocking value of the second timer will be set to 30 minutes.
Thereby, in addition to extending the stand-by period, the long stand-by period also can be avoided to allow user feel not
Convenient.
It should be noted that, in other embodiments, if expiring to the first timer after the first timer initiation
Before, user's equipment 110 receives the second message, then processor 116 can stop the first timer.And
And, processor 116 also will not start the second timer subsequently.
For helping to understand the embodiment of the present invention, example explanation user's equipment 110 and ProSe below will be lifted
Declaration request process between function 135.
Fig. 4 be the embodiment of the present invention declaration request process in user's equipment 110 and ProSe function 135
Between interaction diagrams.Refer to Fig. 4, in step S410, user's equipment 110 starts the first meter
When device, and transmit exploration request (DISCOVERY_REQUEST) to ProSe function 135.Assume
The clocking value of the first timer is 30 seconds.If the probe response from ProSe function 135
(DISCOVERY_RESPONSE) transmitting unsuccessfully (step S440), ProSe function 135 cannot
Receive DISCOVERY_REQUEST, or ProSe function 135 cannot transmit
DISCOVERY_RESPONSE, processor 116, until the first timer expires, will start
Two timers (step S460), but do not transmit DISCOVERY_REQUEST by transceiver 113.
The clocking value assuming the second timer is one minute.Processor 116 until the second timer expires (i.e.,
After one minute), the first timer will be again started up, and transmitted by transceiver 113
DISCOVERY_REQUEST (step S470).
