Fig. 5 is the schematic flow sheet that the present invention realizes neighbouring the second embodiment directly found, second implements Example provides alien frequencies to support the neighbouring transmission directly found instruction for base station for idle UE, and terminal is read in idle state Obtain the scene of the configuration information sending resource pool after taking alien frequencies SIB, implement and comprise the following steps:

Step 500: neighbouring for the alien frequencies support transmission instruction directly found is carried and disappeared in system broadcasts by base station Breath is sent to terminal.

In second embodiment, it is assumed that it is that terminal is autonomous that alien frequencies closes on the type sending resource pool of directly discovery Select resource.

By network management configuration or by inter-base station interface, base station such as eNB obtains and can support on other carrier frequency The neighbouring transmission information directly found, is belonged to including the alien frequencies that can support the neighbouring transmission directly found Frequency information, and PLMN list information.

Step 501: terminal supports the neighbouring transmission directly found instruction according to the alien frequencies received, and passes through Listen to alien frequencies system broadcast message and obtain the neighbouring configuration information sending resource pool directly found.

In this step, terminal can be supported neighbouring according to the alien frequencies received when Serving cell Idle state The transmission instruction directly found, actively receives alien frequencies system broadcast message, it is thus achieved that alien frequencies is neighbouring directly to be found Send resource pool configuration information.

Step 502: terminal uses the neighbouring transmission resource pool directly found of the alien frequencies obtained to send neighbouring straight The existing message of sending and receiving.

When terminal is in Idle state, if received, alien frequencies in described system broadcast message is neighbouring directly to be found The configuration information sending resource pool, type now be terminal from main separation resource type, therefore, eventually It is neighbouring that end can use the transmission resource pool on the carrier frequency of acquisition to send in the case of not changing Serving cell Directly find message.

Fig. 6 is the flow process signal that the present invention realizes neighbouring the 3rd embodiment directly found and the 4th embodiment Figure, the 3rd embodiment is for guiding idle UE to enter connected state, and base station directly configures resource in dedicated signaling The scene of the configuration information in pond, as shown in Figure 6, implements and comprises the following steps:

Step 600: neighbouring for the alien frequencies support transmission instruction directly found is carried and disappeared in system broadcasts by base station Breath is sent to terminal.

In the present embodiment, it is assumed that in base station broadcast and do not differentiate between Serving cell or alien-frequency district and support neighbour The nearly transmission directly found.Such as, base station such as eNB can be in system broadcast message 19 (SIB19) Indicate it to support neighbouring directly discovery, but the configuration information of resource pool is not provided.

Step 601: terminal enters connected state, sends neighbouring directly discovery and asks to base station.

Support after the transmission instruction directly found when terminal receives in system broadcast message, if Terminal needs to send adjacent to directly finding that request (is asked as the software of terminal high level there is a need to transmit neighbouring discovery Will trigger when asking), then terminal can actively enter connected state.

Terminal can carry neighbouring direct in the Side link UE Information message of RRC information Now ask.

Step 602: base station receives neighbouring directly discovery and asks, by neighbouring for the alien frequencies transmission directly found The configuration information of resource pool carries and is sent to terminal in configuration message.

In this step, base station directly will can be sent out with frequency and/or alien frequencies are neighbouring according to load condition between carrier frequency The configuration information sending resource pool is sent to terminal；

Further, base station can also suitably send joining of resource pool according to the prioritizing selection that arranges of self Confidence breath is sent to terminal, and the heavier transmission resource pool of such as load is placed on list front end, and load is lighter Send resource pool and come list rear end, so, in order to terminal selects to send resource according to the order of list Pond.

In the present embodiment, the type sending resource pool includes that terminal primary resource selects, or scheduling resource is joined Put.

Configuration message in this step can be that RRC connection reconfigures (RRC Connection Reconfiguration) message, such as new field are for indicating the neighbouring transmission resource directly found of alien frequencies Pond.Simultaneously, the present embodiment can also include: the transmission resource pool of the discovery of Serving cell also may be used In configuration message, it is sent to terminal to carry simultaneously.

Step 603: the neighbouring transmission resource pool directly found that terminal use obtains sends adjacent to directly sending out Now ask.

In this step, when terminal is in connected state, also include: check that the neighbouring of base station configuration directly finds Resource pool, checks whether mandate and/or PLMN allow to use.If base station is the high preferential of terminal distribution The transmission resource pool of level does not allow to use, and terminal continues checking for the resource pool of second priority.After selecting successfully, Terminal can use the transmission resource pool on selected carrier frequency to send neighbour in the case of not changing Serving cell Closely directly find message.

Referring still to Fig. 6, the 4th embodiment is for guiding idle UE to enter connected state, and base station guiding terminal goes Read the scene of alien frequencies SIB, unlike the 3rd embodiment:

Step 602, the present embodiment are base station is according to load condition between carrier frequency, it is judged that need at alien frequencies Upper transmission, is allocated to terminal by neighbouring for the alien frequencies support transmission instruction directly found；

By network management configuration or by inter-base station interface, base station such as eNB obtains and can support on other carrier frequency The neighbouring transmission information directly found, is belonged to including the alien frequencies that can support the neighbouring transmission directly found Frequency information and PLMN list information.

Further, base station can also configure the transmission resource that this carrier frequency, i.e. Serving cell find simultaneously Pond.So, when terminal selects failure or other reasons cannot use alien frequencies resource pool because of PLMN, can To use the resource pool of this Serving cell to carry out the neighbouring transmission directly finding message.

Unlike the 3rd embodiment, now, the type of alien frequencies resource pool can only be primary resource choosing.

But, the type sending resource pool that Serving cell finds can include that terminal primary resource selects, Or scheduling resource configuration.

In step 603, the present embodiment implements and is: when terminal is in connected state, checks that alien frequencies props up Hold the neighbouring mandate sent in instruction directly found and/or whether PLMN allows to use, if do not permitted Permitted to use, then, base station checks the resource pool self whether being also configured with Serving cell；If passed through Authorizing and/or PLMN checks, terminal reads in the system broadcasts resource information on alien frequencies when connected state Send resource pool configuration information；

Then, terminal can use the transmission on the carrier frequency of acquisition to provide in the case of not changing Serving cell Pond, source sends adjacent to directly finding message.
