- the first embodiment of the present application provides a method for selecting a core network device.
- the access network device selects a core network device for the accessed UE.
- the method may be applicable to the MTC UE.
- the core network device may be a Serving GPRS Supporting Node (SGSN), and the access network device may be an RNC
- the core network device may be a Mobility Management Entity (MME), and the access network device may be an e-Node B.
- MME Mobility Management Entity
- the method for selecting the core network device includes the following steps:
- Step 301 The access network device (RNC or e-Node B) determines the device type of the UE.
- the access network device needs to determine the device type of the UE, and the device type of the UE may be Non-MTC. If the device type of the UE is a non-MTC UE, step 302 is performed; when the device type of the UE is an MTC UE, step 303 is performed.
- Step 302 The access network device selects a core network device (such as an SGSN or an MME) to be accessed by the UE, and the selection mode is implemented in the existing manner, and is not repeatedly described in the embodiment of the present application.
- a core network device such as an SGSN or an MME
- Step 303 The access network device determines an MTC group identifier corresponding to the UE.
- the MTC UEs may be grouped into an MTC group and differentiated by using the MTC group identifier. Therefore, when determining that the UE is an MTC UE, the access network device may The MTC group identifier corresponding to the MTC UE is determined.
- the core network device GGSN or SGW of the 3G mobile communication network or the 4G mobile communication network may allocate bearer resources according to the MTC group identifier, and the MTC UE may access the 3G mobile communication network or 4G.
- the bearer resources corresponding to the MTC group to which it belongs are used to solve the problem that a large number of network resources are occupied when a large number of MTC UEs access the 3G mobile communication network or the 4G mobile communication network.
- Step 304 The access network device determines whether the MTC group identifier has a corresponding core network device. When the MTC group identifier corresponds to the core network device, step 305 is performed. When the MTC group identifier does not correspond to the core network device, step 306 is performed. .
- the access network device also needs to maintain the correspondence between the MTC group identifier and the core network device. It is to be noted that, based on the correspondence, for the MTC UE accessing the mobile communication network in the MTC group, the MTC UE may determine that the MTC group identifier does not correspond to the core network device; The group is not the first MTC UE to access the mobile communication network. During the access process of the MTC UE, it can be determined that the MTC group identifier corresponds to the core network device.
- Step 305 The access network device selects a core network device corresponding to the MTC group identifier as the core network device accessed by the UE.
- UE1, UE2, and UE3 are all MTC UEs, and UE1, UE2, and UE3 are composed.
- the MTC group is identified by using the MTC group identifier A. It is assumed that the UE1 first accesses the mobile communication network, and the core network device selected by the access network device for the UE1 is the core network device A; then when the UE2 accesses the mobile communication network It is determined that the MTC group identifier A corresponding to UE2 has a corresponding core network device A, and the access network device selects the core network device A as the core network device accessed by UE2; for the type, the access network device will also select the The core network device A serves as the core network device accessed by the UE3.
- Step 306 The access network device selects the core network device as the core network device accessed by the UE from the core network device pool, and records the correspondence between the MTC group identifier corresponding to the UE and the selected core network device.

- the weight of the core network device and the preset policy the core network device is selected from the core network device pool as the core network device accessed by the UE in the MTC group.
- the preset policy may be: making the selection probability of each core network device proportional The weight of each core network device.
- a core network device is usually organized in a pool manner; when a UE accesses a 3G mobile communication network or a 4G mobile communication network, the access network device firstly accesses the core network device.
- the pool determines the core network device to be accessed for the UE; after that, the selected core network device requests the GGSN or the SGW to allocate the bearer resource, and notifies the access network device of the allocation result of the GGSN or the SGW;
- a bearer resource is allocated to the UE, and a binding relationship is established.
- the core network device notifies the GGSN or the SGW of the allocation result, and the GGSN or the SGW establishes a binding relationship.
- the access network device selects the core network device from the core network device pool as the core network device that the UE accesses, and specifically: the access network device is configured from the core network device pool according to the load balancing principle.
- the UE determines the core network device to access. Specifically, each core network device in the core network device pool allocates a weight according to its capacity, and the access network device selects the core network device according to the weight, so that the selection probability of each core network device is proportional to the weight, thereby Load balancing between core network devices in the core network device pool.

- the selection process of the core network device does not distinguish the UE type, and does not distinguish the MTC group to which the MTC UE belongs;
- the MTC UEs are evenly distributed on the core network devices in the core network device pool. Since the bearer allocation process of the core network is triggered by the selected core network device, the existing MTC group cannot be implemented in the prior art.
- the MTC UE uses the requirements of the public core network to carry resources.
- the MTC UE accesses the core network and occupies a large number of networks. The problem of resources.
- the access network device in the networking mode of the core network device, the access network device needs to consider the device type of the UE (such as the MTC UE or It is a non-MTC UE and information such as the MTC group identifier to which the MTC UE belongs, so that when a large number of MTC UEs access the 3G mobile communication or the 4G mobile communication network, the problem of occupying a large amount of core network resources is solved; and the same MTC group can be made.
