Description

Communication method, device and system

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication method, apparatus, and system.

Background

A Mobility Management Entity (MME) pool (MMEPOOL) mechanism is introduced in the 3GPP standard, which can implement resource sharing and load balancing among multiple MMEs. Specifically, the MME pool is composed of one or more MMEs, all MMEs in the MME pool correspond to the same Tracking Area (TA), and a base station (eNB) in the Tracking Area is fully connected to the MMEs in the MME pool (i.e., the eNB is simultaneously connected to each MME in the MME pool). When a User Equipment (UE) newly enters the tracking area, an eNB selects a certain MME in an MME pool for the UE to attach according to a load balancing mechanism; when the UE roams in the MME pool, the MME serves the UE, and switching among the MMEs is not needed.

In the prior art, the load balancing function of the MME pool enables the MME pool to have a certain disaster tolerance capability. For example: when a certain MME in the MME pool has a fault, after the eNB identifies the fault of the MME, the faulty MME is not considered when MME selection is carried out on newly accessed UE; and for the UE which is registered in the faulty MME, the eNB transfers the new service initiated by the UE to other normal MME in the MME pool.

However, when the UE registered in the failed MME does not actively initiate a new service, the UE only performs registration in another normal MME through a periodic Tracking Area Update (TAU) procedure. However, the TAU period is long (generally about one hour), during which the called service of the UE is not reachable, which affects the service of the user.

Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present invention, and as shown in fig. 1, the communication system includes: MME pool, base station and terminal. Wherein, the MME pool is composed of one or more MMEs, all MMEs in the MME pool correspond to the same Tracking Area (TA), and a base station (eNB) in the Tracking Area is fully connected with the MMEs in the MME pool (i.e. the eNB is simultaneously connected to each MME in the MME pool). The UE may access the network through one of the base stations in fig. 1, and register with any MME in the MME pool.

As shown in fig. 1, in the networking of the MME pool, since the eNB is connected to a plurality of MMEs in the MME pool, when a UE in a tracking area corresponding to the MME pool initiates a new service, the eNB may select one MME from the pool for the UE according to a load balancing principle.

For descriptive purposes, the MME pool networking shown in fig. 1 is simplified, assuming that MME1 and MME2 are included in the MME pool, the eNB is connected to MME1 and MME2, respectively. The following describes the load balancing procedure of the MME pool.

Assuming that the effective user capacity of the MME1 is 4 and the effective user capacity of the MME2 is 3, the eNB will access the UE to the MME1 and the MME2 according to a ratio of 4:3, and the specific distribution effect depends on the implementation manner of the eNB. It can be understood that the eNB needs to first obtain load weight information of each MME.

In one embodiment, when the eNB establishes S1 connection with each MME, the MME notifies the eNB of its own load weight. Specifically, a user respectively configures the load weight of each MME according to the proportional relation of the available capacity of each MME in an MME pool; the MME stores respective load weight, the eNB initiates an SCTP establishment request to the MME and the establishment is successful, the eNB sends an S1Setup Req message to the MME to establish S1 connection, the MME sends an S1Setup Rsp message to the eNB to retransmit the load weight of the MME to the eNB, and the eNB stores the load weight information of the MME as a basis for selecting the MME when the UE is accessed.

In another embodiment, the MME notifies the eNB of its own load weight after the connection setup at S1. Specifically, a user modifies the load weight of the MME according to the network condition, the MME stores the modified load weight, and the MME actively sends an MME configuration update message to all connected enbs, wherein the MME configuration update message carries the load weight information of the MME, and the eNB updates the load weight of the MME, which is used as a basis for selecting the MME during subsequent UE access.

Through the process of load balancing of the MME networking, the MME pool has certain disaster tolerance capability. When a certain MME in the MME pool has a fault, the eNB can identify that the MME is in a fault state by monitoring the state of the S1 link, and further, when the eNB selects the MME of a newly accessed user, the faulty MME is not considered any more, so that disaster recovery of the MME pool is realized.

However, for a UE that has been registered in a failed MME, in the prior art, only when the UE actively initiates a new service, the eNB will select a normal MME in the MME pool for the UE to register. Under the condition that the UE does not actively initiate a new service, the UE only realizes registration in other normal MME through a periodic TAU flow. Because the TAU period is long (generally about one hour), the called service of the UE is not reachable during this period, which affects the service of the user.

In the communication system provided by the embodiment of the invention, when the eNB detects the failure of the MME in the MME pool, the eNB can timely inform the UE to re-register to other normal MMEs in the MME pool, thereby avoiding influencing the service of the user.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a first flowchart of a communication method according to an embodiment of the present invention, where the method of this embodiment may be executed by any eNB shown in fig. 1, and as shown in fig. 2, the method of this embodiment may include:

s201: and determining the state of each MME according to the state of an S1 link between the base station and each MME in the MME pool.

S202: and acquiring an identifier of a first MME according to the state of each MME, wherein the first MME is the MME in the failure state in the MME pool.

Specifically, the eNB may monitor, in real time or periodically, the S1 link state between the base station and each MME, and for a certain S1 link, if the S1 link state is normal, it may be determined that the corresponding MME is in a normal state; if the S1 link status is abnormal, it may be determined that the corresponding MME is in a failure status.

And when one or more MME in the MMEs are determined to be in the fault state, acquiring the identification of the MME in the fault state. In specific implementation, when the eNB establishes S1 connection with each MME, the eNB has already acquired the identification information of each MME and has already established a correspondence between each S1 link and each MME identification, and according to the correspondence, the eNB can acquire the identification of the MME corresponding to the S1 link in the abnormal state.

S203: broadcasting a first message to a terminal, wherein the first message comprises an identifier of the first MME, so that the terminal which is registered to the first MME is re-registered to a second MME through a network registration process, and the second MME is an MME in a normal state in the MME pool.

After the eNB acquires the identifier of the MME in the failure state, the eNB may broadcast a first message to all UEs accessing the eNB, and the first message carries the identifier of the MME in the failure state.

The first message may multiplex an existing message in the prior art, or may be implemented by negotiating to add a new message between the eNB and the UE.

It can be understood that, at a certain time, there may be one or more MMEs in the MME pool in the failure state, and therefore, the first message may include an identifier of one first MME or may include identifiers of a plurality of first MMEs, and the embodiment does not specifically limit the number of the identifiers of the first MME included in the first message.

Since the eNB sends the first message in a broadcast manner, all UEs accessing the eNB may receive the first message. After receiving the first message, the UE may determine whether it is registered in the failed MME according to the identifier of the failed MME carried in the first message, and if so, may re-register the failed MME in the normal MME pool through a network registration procedure.

Specifically, when the UE accesses the network, the network may allocate a Globally unique temporary UE Identity (GUTI) to the UE, where the GUTI includes an identifier of an MME registered by the UE. Therefore, after the UE accesses the network, the UE can obtain the identity of the MME that has registered itself according to the received GUTI. Further, the UE may compare the identifier of the MME that has registered with the identifier of the MME in the failure state carried in the first message, and if the identifier of the MME is the same as the identifier of the MME in the failure state, determine that the UE is registered in the MME in the failure state.

After the UE judges that the UE is in the MME in the fault state, the UE can be registered to the MME in the normal state in the MME pool again through the existing network registration process. The network registration procedure is not limited in this embodiment.

According to the communication method provided by the embodiment of the invention, the state of each MME is determined according to the state of an S1 link between the base station and each MME in an MME pool, the identifier of a first MME is obtained according to the state of each MME, the first MME is the MME in a fault state in the MME pool, a first message is broadcasted to a terminal, the first message comprises the identifier of the first MME, so that the terminal which is registered to the first MME is re-registered to a second MME through a network registration process, and the second MME is the MME in a normal state in the MME pool; by the communication method, after the MME in the MME pool has a fault, the UE which is registered in the MME can timely acquire the state of the MME and timely re-register in the MME in a normal state in the MME pool through a network registration process, so that the UE cannot be in a service unreachable state for a long time, and the service of a user is prevented from being influenced.

Optionally, the broadcast duration of the paging message is less than a period of updating TAU in the tracking area.

S304: the terminal determines whether the identity of the registered MME is the same as the identity of the first MME, and if so, executes S305.

S305: and the terminal sends an attachment request to the base station and registers according to a second MME in an MME pool selected by the base station for the UE in the attachment process, wherein the second MME is an MME in a normal state in the MME pool.

In this embodiment, after receiving the paging message, the UE immediately sends an attach request to the eNB if it is determined that the identifier of the MME that has registered with the UE is the same as the identifier of the first MME carried in the paging message.

S403: and broadcasting a system message to the UE by the base station, wherein the system message comprises the identifier of the first MME.

In this embodiment, after detecting that an MME in the MME pool fails, the eNB broadcasts the identifier of the MME in the failure state to the UE through a system message. The system message may be an mib (master Information block) message, or may be any one of sib (system Information blocks) messages, which is not specifically limited in this embodiment.

Optionally, the broadcast duration of the system message is less than the period of tracking area update TAU.
