Background

Proximity Services (ProSe) is proposed by The 3rd Generation Partnership Project (3 GPP), and one of The applications of ProSe is to enable two terminals in a relatively close distance to discover each other in a direct or indirect manner. In the process of discovering each other between two terminals, one terminal (announcing UE) of the two terminals (UE) is required to acquire ProSe broadcast resources from a base station (eNodeB), so as to broadcast a ProSe service identifier according to the acquired ProSe broadcast resources, so that the other terminal (monitering UE) of the two terminals discovers a broadcast terminal according to the broadcasted ProSe service identifier.

in the prior art, if a UE needs to enter a radio resource control connected state, so as to request an eNodeB to acquire a dedicated ProSe broadcast resource allocated to the UE, and broadcast a ProSe service identifier using the dedicated ProSe broadcast resource, the UE must be kept in a radio resource control connected state during this period, and once the UE is switched from the radio resource control connected state to an idle state, the dedicated ProSe broadcast resource allocated to the UE is no longer available. Obviously, in the prior art, the UE must remain in the radio resource control connected state to broadcast the ProSe service identifier using the proprietary ProSe broadcast resource, which results in increased power consumption of the UE.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.

fig. 1 is a flowchart illustrating a resource scheduling method according to a first embodiment of the present invention, as shown in fig. 1, including:

101. A Mobility Management Entity (MME) receives a first message.

the first message is sent to an MME by the UE through a target eNodeB when the target eNodeB resided after the UE cell is reselected is different from a source eNodeB resided before the UE cell is reselected; the first message is for requesting allocation of ProSe broadcast resources for the UE.

102. the MME instructs the destination eNodeB to allocate the ProSe broadcast resource requested by the first message to the UE.

Optionally, before the MME instructs the destination eNodeB to allocate resources to the UE, the MME generates a ProSe resource code (ProSe resource code), where the ProSe resource code includes a randomly generated random code and an eNodeB identifier of the destination eNodeB where the UE resides when the ProSe resource code is generated. And sending a ProSe broadcast resource allocation request containing a ProSe resource code to a target eNodeB of the UE, so that after the target eNodeB allocates the ProSe broadcast resources to the UE, a corresponding relation between the ProSe resource code and the ProSe broadcast resources allocated to the UE is established. The corresponding relation is used for releasing the ProSe broadcast resource corresponding to the ProSe resource code by the target eNodeB according to the ProSe resource code.

Or, optionally, the MME sends a ProSe broadcast resource allocation request including an identifier of the UE to a destination eNodeB of the UE, so that the destination eNodeB establishes a correspondence between the identifier of the UE and a ProSe broadcast resource allocated to the UE after allocating the ProSe broadcast resource to the UE according to the indication of the ProSe broadcast resource allocation request; and the corresponding relation is used for releasing the ProSe broadcast resource corresponding to the UE identifier by the target eNodeB according to the UE identifier.

further, the resource scheduling method may further include: the MME instructs a source eNodeB of the UE to release the ProSe broadcast resources that have been allocated to the UE.

optionally, after receiving the first message, the MME determines whether ProSe service information of the UE is already stored thereon, where the service information includes a ProSe resource code, and the ProSe service information indicates that a broadcast resource has been allocated to the UE. If the MME determines that the ProSe resource code of the UE is stored, sending a second message to the source eNodeB according to an eNodeB identifier in the ProSe resource code, namely a source eNodeB identifier; the second message is used for instructing the source eNodeB to release the ProSe broadcast resources which are allocated for the UE before, and the second message contains a ProSe resource code, so that the source eNodeB is matched with the corresponding ProSe broadcast resources according to the ProSe resource code; a first codeword in the ProSe resource code is randomly generated and a second codeword is used to identify the source eNodeB that allocates the ProSe broadcast resources.

it should be noted that the first message may be a service request message and/or a Tracking Area Update (TAU) message.

or, optionally, after receiving the first message, the MME determines whether ProSe service information of the UE is stored thereon, where the ProSe service information is used to indicate that a ProSe service exists on the UE and a ProSe broadcast resource has been allocated to the UE. If the MME determines that the ProSe service information of the UE is stored, a second message is sent to the source eNodeB; the second message is used for instructing the source eNodeB to release the broadcast resource that the source eNodeB has allocated for the UE, and the second message includes the identifier of the UE, so that the eNodeB matches the corresponding ProSe broadcast resource according to the identifier of the UE.

In the embodiment of the invention, when the target eNodeB resided after the cell reselection is carried out by the UE in the idle state is different from the source eNodeB resided before the cell reselection of the UE, the UE requests a network entity to acquire the ProSe broadcast resource distributed by the target eNodeB, and in addition, the source eNodeB can be triggered to release the ProSe broadcast resource distributed by the target eNodeB, thereby solving the technical problem that the UE in the prior art can broadcast the ProSe service identifier by using the special ProSe broadcast resource only when the UE is kept in a wireless resource control connection state, so that the electric quantity consumption of the UE is increased.

fig. 2 is a schematic flowchart of a resource scheduling method according to a second embodiment of the present invention, where before and after a cell reselection of a UE, an eNodeB is changed, the UE resides in an eNodeB B before the cell reselection, and the UE resides in an eNodeB a after the cell reselection in this embodiment, as shown in fig. 2, the resource scheduling method includes:

201. The UE performs a cell reselection procedure.

202. And the UE determines that the eNodeB where the UE resides is changed before and after cell reselection.

Specifically, the UE determines whether an eNodeB change has occurred according to the received broadcast message, that is, whether an eNodeB where the UE resides before and after cell reselection has changed, and if so, performs the subsequent steps.

203. If the resident eNodeBs before and after the UE cell reselection are changed and the UE has ongoing ProSe service, the UE sends a TAU message containing an indication of applying for ProSe broadcast resources to the currently resident eNodeB A.

204. eNodeB A judges whether MME serving UE changes, if MME does not change, then execute steps 204a-208 a; if the MME changes steps 204b-209b are performed.

it should be noted that, the eNodeB a determining whether the MME serving the UE changes refers to whether the MME serving the UE changes before and after the eNodeB a receives the TAU message, that is, whether the MME to which the UE is attached changes, when the MME changes, the source MME to which the UE is attached before the TAU procedure is called MME B, and the target MME to which the UE is reattached is called MME a currently attached. If the MME is not changed, the MME to which the UE is currently attached is recorded as MME A.

204a, if the eNodeB A determines that the MME serving the UE is not changed, sending the TAU message containing the indication of applying for the ProSe broadcast resource to the MME A serving the UE after the eNodeB A receives the TAU message.

205a, MME a determines whether ProSe service information of the UE is stored therein, if so, executes steps 206a-208 a; otherwise 208a is executed directly.

specifically, when the MME a stores ProSe service information of the UE, the MME a extracts an old Global Cell Identity (ECGI) that is already stored in the context of the UE, so that the subsequent MME a can determine, according to the old ECGI value, an eNodeB B where the UE resides last time, and perform a process of releasing ProSe broadcast resources allocated to the UE on the eNodeB B.

in this embodiment, the ProSe service information stored in the MME may specifically refer to ProSe broadcast service indication information, which indicates that the UE is executing a ProSe discovery service and allocates broadcast resources to the UE; or the ProSe service identifier, ProSe application ID, existing on the UE, optionally includes parameters of each ProSe application ID resource, such as bandwidth, power, time interval, and the like.

206a, MME A determines eNodeB B according to the old ECGI value and sends UE context release (UE context release) information carrying UE identification to eNodeB B, so that eNodeB releases UE context, including information such as UE identification release and broadcast resource distributed for UE.

the Identity of the UE may be an identifier of a UE such as an International Mobile Subscriber Identity (IMSI) or a Temporary Mobile Subscriber Identity (S-Temporary Mobile Subscriber Identity, S-TMSI).

207a, eNodeB B releases the context of the UE, and then sends a UE context release complete message to MME a.

after steps 206a, 207a are completed, the MME a deletes the old ECGI and saves the new ECGI contained in the TAU message sent by the UE in step 203.

208a, other flows of the TAU procedure are performed as normal procedures.

204B, if the eNodeB A judges that the MME serving the UE needs to be changed, the eNodeB A selects a new MME for the UE, the MME serving the UE after the selected eNodeB A receives the TAU message is taken as the MME A, the source MME to which the UE is attached before the process is taken as the MME B, and the eNodeB A sends the TAU message containing the ProSe broadcast resource application instruction to the MME A.

205B, MME A executes the process of obtaining UE context from MME B.
